Why focus on close reading?
“One of the key requirements of the Common Core State Standards for Reading is that all students…
must be able to read and comprehend independently and proficiently the kinds of complex texts
commonly found in college and careers.”
CCSS Appendix A, pg. 2
Through close reading of complex text, students can develop thinking strategies and perseverance
required to understand and be successful with difficult or unfamiliar texts. Close reading engages the
reader in a thorough analysis of the text. The only evidence or information the reader relies on is
what the author has directly included in the text.
Effective close reading instruction motivates and rewards all students for reading inquisitively;
focuses on building knowledge through the strategic use of text-dependent questions; and prepares
students for the kinds of reading tasks they will encounter in college and careers.
A characteristic of close reading is that teachers use text-dependent questions to prompt students to
return to the text. Students are guided to deeply analyze and appreciate various aspects of the text,
such as key vocabulary and how its meaning is shaped by context; to focus on the author’s word
choices and repetition, specific sentences, literary devices, or how particular passages contain
information that is key to the learning (literal meaning); to determine inferential meaning (mood,
tone, author’s purpose) and make connections.
Close reading instruction facilitated by a skilled teacher is one of many research-based outcomes that
can help students become independent and proficient readers of increasingly complex texts.
The following text exemplars are taken from the Common Core State Standards Appendix B
http://www.corestandards.org/assets/Appendix_B.pdf and will provide teachers with a starting point
for introducing authentic text into their classroom routine. A selection of text-dependent questions
and performance tasks have been provided with each exemplary text for teachers to use as they
incorporate the goal of close reading into their instruction. Academic vocabulary has also been
highlighted that may need to be defined before teachers use the selected text.

(1992)
Mars is very cold and very dry. Scattered across the surface are many giant volcanoes. Lava covers much
of the land.
In Mars’ northern half, or hemisphere, is a huge raised area. It is about 2,500 miles wide. Astronomers
call this the Great Tharsis Bulge.
There are four mammoth volcanoes on the Great Tharsis Bulge. The largest one is Mount Olympus, or
Olympus Mons. It is the biggest mountain on Mars. Some think it may be the largest mountain in the
entire solar system.
Mount Olympus is 15 miles high. At its peak is a 50 mile wide basin. Its base is 375 miles across. That’s
nearly as big as the state of Texas!
Mauna Loa, in Hawaii, is the largest volcano on earth. Yet, compared to Mount Olympus, Mauna Loa
looks like a little hill. The Hawaiian volcano is only 5½ miles high. Its base, on the bottom of the Pacific
Ocean, is just 124 miles wide.
Each of the three other volcanoes in the Great Tharsis Bulge are over 10 miles high. They are named
Arsia Mons, Pavonis Mons, and Ascraeus Mons.

Simon, Seymour. Horses. New York: HarperCollins, 2006. (2006)
Horses move in four natural ways, called gaits or paces. They walk, trot, canter, and gallop. The walk is
the slowest gait and the gallop is the fastest.
When a horse walks, each hoof leaves the ground at a different time. It moves one hind leg first, and
then the front leg on the same side; then the other hind leg and the other front leg. When a horse walks,
its body swings gently with each stride.
When a horse trots, its legs move in pairs, left front leg with right hind leg, and right front leg with left
hind leg. When a horse canters, the hind legs and one front leg move together, and then the hind legs
and the other foreleg move together.
The gallop is like a much faster walk, where each hoof hits the ground one after another. When a horse
gallops, all four of its hooves may be flying off the ground at the same time.
Horses are usually described by their coat colors and by the white markings on their faces, bodies, legs,
and hooves.
Brown horses range in color from dark brown bays and chestnuts to golden browns, such as palominos,
and lighter browns such as roans and duns.
Partly colored horses are called pintos or paints. Colorless, pure-white horses—albinos—are rare. Most
horses that look white are actually gray.
Skewbalds have brown-and-white patches. Piebalds have black and white patches. Spotteds have dark
spots on a white coat or white spots on a dark coat.

Lauber, Patricia. Hurricanes: Earth’s Mightiest Storms. New York: Scholastic, 1996. (1996)
From “The Making of a Hurricane”
Great whirling storms roar out of the oceans in many parts of the world. They are called by several
names—hurricane, typhoon, and cyclone are the three most familiar ones. But no matter what they are
called, they are all the same sort of storm. They are born in the same way, in tropical waters. They
develop the same way, feeding on warm, moist air. And they do the same kind of damage, both ashore
and at sea. Other storms may cover a bigger area or have higher winds, but none can match both the
size and the fury of hurricanes. They are earth’s mightiest storms.
Like all storms, they take place in the atmosphere, the envelope of air that surrounds the earth and
presses on its surface. The pressure at any one place is always changing. There are days when air is
sinking and the atmosphere presses harder on the surface. These are the times of high pressure. There
are days when a lot of air is rising and the atmosphere does not press down as hard. These are times of
low pressure. Low-pressure areas over warm oceans give birth to hurricanes.

In early times, no one knew how volcanoes formed or why they spouted red-hot molten rock. In modern
times, scientists began to study volcanoes. They still don’t know all the answers, but they know much
about how a volcano works.
Our planet is made up of many layers of rock. The top layers of solid rock are called the crust. Deep
beneath the crust is the mantle, where it is so hot that some rock melts. The melted, or molten, rock is
called magma.
Volcanoes are formed when magma pushes its way up through the crack in Earth’s crust. This is called a
volcanic eruption. When magma pours forth on the surface, it is called lava.

Hall, Leslie. “Seeing Eye to Eye.” National Geographic Explorer. September 2009. (2009)
A hungry falcon soars high above Earth. Its sharp eyes scan the ground. Suddenly, it spies something
moving in the grass. The falcon dives toward it.
Far below, a gray field mouse scurries through the grass. Its dark, beady eyes search constantly for
danger. With eyes on either side of its head, the mouse can see almost everything around it.
Will the mouse see the falcon in time to escape? Or, will the speedy falcon catch the prey it spied from
far above? Whatever happens, one thing is clear: Without eyes, neither animal has a good chance.
Why? Eyes help many animals make sense of the world around them - and survive. Eyes can guide the
falcon to dinner or help the mouse see a perfect place to hide.
Animal eyes come in many different shapes, sizes, colors, and even numbers. Yet they do the same job.
They all catch light. With help from the brain, eyes turn light into sight.
Eyes work in the same way for people. Look at this page. You may think you see words and pictures.
Believe it or not, you don’t. All you see is light bouncing off the page. How is this possible? The secret is
in the rules of light.
Light Rules
Light is a form of energy, like heat or sound. It can come from a natural source, like the sun, or artificial
sources, like a lamp or a flashlight.
Light is the fastest known thing. It travels in waves and in nearly straight lines. In air, it can speed
299,700 kilometers (186,200 miles) per second. It can race from the sun to Earth in just over eight
minutes! Light doesn’t always travel so fast. For example, water or glass can slow light down, but just a
bit.
Light may seem to break all driving speed laws. Yet there are certain rules it always follows. Light
reflects, or bounces off objects. It also refracts, or bends. And it can be absorbed, or soaked up, by
objects. These rules of light affect what, and how, we see.
Light! Eyes!
Imagine this scene: You’re at your desk happily reading Explorer magazine. Light from your desk lamp
scatters in all directions.
Light hits the page. Some bounces off the page, or reflects. It changes direction. It’s a little like how
sound bounces off a wall. Now some of this reflected light is traveling right toward your face. Don’t
duck! For you to see Explorer, some of this light has to enter your eyes. Objects become visible when
light bounces off them.
Your eyes are light catchers. Yet it takes more than catching light to see an image. Your eyes also have to
bend light. Here’s how.
First, light hits your cornea. That’s the clear covering on the front of your eyeball. The cornea refracts, or
bends, light.
And Action!
Is your cornea super strong? No! Think about how light travels more slowly through water. The same
thing happens in your cornea. As light passes through the cornea, it slows down. That makes the light
change direction, or bend.
Next, light enters your pupil, the dark center part of your eye. It passes through your lens. The lens
bends light, too. What’s the big deal about bending light? That’s how your eyes focus, or aim the light to
make a clear image.
The image appears on your retina at the back of your eyeball. It’s like a movie. Playing Today at a
Theater in Your Eye: Explorer magazine! There’s only one problem. The image is upside down. Luckily,
your brain flips the image right side up. That’s pretty smart!

Ronan, Colin A. “Telescopes.” The New Book of Knowledge. New York: Scholastic, 2010. (2010)
You can see planets, stars, and other objects in space just by looking up on a clear night. But to really see
them--to observe the craters on the moon, the rings around Saturn, and the countless other wonders in
our sky--you must use a telescope.
A telescope is an instrument used to produce magnified (enlarged) images of distant objects. It does this
by gathering and focusing the light or other forms of electromagnetic radiation emitted or reflected by
those objects. The word “telescope” comes from two Greek words meaning “far” and “see.”
Kinds of Telescopes
There are many different types of telescopes, both optical and non-optical. Optical telescopes are
designed to focus visible light. Non-optical telescopes are designed to detect kinds of electromagnetic
radiation that are invisible to the human eye. These include radio waves, infrared radiation, X rays,
ultraviolet radiation, and gamma rays. The word “optical” means “making use of light.”
Some telescopes are launched into space. These telescopes gain clearer views. And they can collect
forms of electromagnetic radiation that are absorbed by the Earth’s atmosphere and do not reach the
ground.
Optical Telescopes
Different types of optical telescopes gather and focus light in different ways. Refracting telescopes, or
refractors, use lenses. Reflecting telescopes, or reflectors, use mirrors. And catadioptric telescopes, or
catadioptrics, use a combination of lenses and mirrors. The main lens or mirror in an optical telescope is
called the objective.
Refracting Telescopes. A refracting telescope is typically a long, tube-shaped instrument. The objective is
a system of lenses at the front end of the tube (the end facing the sky). When light strikes the lenses, it
is bent and brought to a focus within the tube. This forms an image of a distant object. This image can
be magnified by the eyepiece. This consists of a group of small lenses at the back of the tube. A camera
can replace or be added to the eyepiece. Then photographs can be taken of celestial objects. For many
years, these cameras used film. Today most are equipped with charge-coupled devices (CCD’s). These
devices use semiconductor chips to electronically capture images. CCD’s are similar to the devices in
home digital cameras and video camcorders. However, the CCD’s used by astronomers are usually
extremely sensitive to light.

“Geology.” U*X*L Encyclopedia of Science. Edited by Rob Nagel. Farmington Hills, Mich.: Gale
Cengage Learning, 2007. (2007)
Geology is the scientific study of Earth. Geologists study the planet—its formation, its internal structure,
its materials, its chemical and physical processes, and its history. Mountains, valleys, plains, sea floors,
minerals, rocks, fossils, and the processes that create and destroy each of these are all the domain of
the geologist. Geology is divided into two broad categories of study: physical geology and historical
geology.
Physical geology is concerned with the processes occurring on or below the surface of Earth and the
materials on which they operate. These processes include volcanic eruptions, landslides, earthquakes,
and floods. Materials include rocks, air, seawater, soils, and sediment. Physical geology further divides
into more specific branches, each of which deals with its own part of Earth’s materials, landforms, and
processes. Mineralogy and petrology investigate the composition and origin of minerals and rocks.
Volcanologists study lava, rocks, and gases on live, dormant, and extinct volcanoes. Seismologists use
instruments to monitor and predict earthquakes and volcanic eruptions.
Historical geology is concerned with the chronology of events, both physical and biological, that have
taken place in Earth’s history. Paleontologists study fossils (remains of ancient life) for evidence of the
evolution of life on Earth. Fossils not only relate evolution, but also speak of the environment in which
the organism lived. Corals in rocks at the top of the Grand Canyon in Arizona, for example, show a
shallow sea flooded the area around 290 million years ago. In addition, by determining the ages and
types of rocks around the world, geologists piece together continental and oceanic history over the past
few billion years. Plate tectonics (the study of the movement of the sections of Earth’s crust) adds to
Earth’s story with details of the changing configuration of the continents and oceans.

“Space Probe.” Astronomy & Space: From the Big Bang to the Big Crunch. Edited by Phillis Engelbert.
Farmington Hills, Mich.: Gale Cengage Learning, 2009. (2009)
A space probe is an unpiloted spacecraft that leaves Earth’s orbit to explore the Moon, planets,
asteroids, comets, or other objects in outer space as directed by onboard computers and/or instructions
sent from Earth. The purpose of such missions is to make scientific observations, such as taking pictures,
measuring atmospheric conditions, and collecting soil samples, and to bring or report the data back to
Earth.
Numerous space probes have been launched since the former Soviet Union first fired Luna 1 toward the
Moon in 1959. Probes have now visited each of the eight planets in the solar system.
In fact, two probes—Voyager 1 and Voyager 2—are approaching the edge of the solar system, for their
eventual trip into the interstellar medium. By January 2008 Voyager 1 was about 9.4 billion miles (15.2
billion kilometers) from the Sun and in May 2008 it entered the heliosheath (the boundary where the
solar wind is thought to end), which is the area that roughly divides the solar system from interstellar
space. Voyager 2 is not quite as far as its sister probe. Voyager 1 is expected to be the first human space
probe to leave the solar system. Both Voyager probes are still transmitting signals back to Earth. They
are expected to help gather further information as to the true boundary of the solar system.
The earliest probes traveled to the closest extraterrestrial target, the Moon. The former Soviet Union
launched a series of Luna probes that provided humans with first pictures of the far side of the Moon. In
1966, Luna 9 made the first successful landing on the Moon and sent back television footage from the
Moon’s surface.
The National Aeronautics and Space Administration (NASA) initially made several unsuccessful attempts
to send a probe to the Moon. Not until 1964 did a Ranger probe reach its mark and send back thousands
of pictures. Then, a few months after Luna 9, NASA landed Surveyor on the Moon.
In the meantime, NASA was moving ahead with the first series of planetary probes, called Mariner.
Mariner 2 first reached the planet Venus in 1962. Later Mariner spacecrafts flew by Mars in 1964 and
1969, providing detailed images of that planet. In 1971, Mariner 9 became the first spacecraft to orbit
Mars. During its year in orbit, Mariner 9’s two television cameras transmitted footage of an intense
Martian dust storm, as well as images of 90 percent of the planet’s surface and the two Martian natural
satellites (moons).
Encounters were also made with Mars in 1976 by the U.S. probes Viking 1 and Viking 2. Each Viking
spacecraft consisted of both an orbiter and a lander. Viking 1 made the first successful soft landing on
Mars on July 20, 1976. Soon after, Viking 2 landed on the opposite side of the planet. The Viking orbiters
made reports on the Martian weather and photographed almost the entire surface of the planet.

California Invasive Plant Council. Invasive Plant Inventory. http://www.calipc.org/ip/inventory/index.php. 2006–2010. (2010)
The Inventory categorizes plants as High, Moderate, or Limited, reflecting the level of each species’
negative ecological impact in California. Other factors, such as economic impact or difficulty of
management, are not included in this assessment. It is important to note that even Limited species are
invasive and should be of concern to land managers.
Although the impact of each plant varies regionally, its rating represents cumulative impacts statewide.
Therefore, a plant whose statewide impacts are categorized as Limited may have more severe impacts in
a particular region. Conversely, a plant categorized as having a High cumulative impact across California
may have very little impact in some regions.
The Inventory Review Committee, Cal-IPC staff, and volunteers drafted assessments for each plant
based on the formal criteria system described below. The committee solicited information from land
managers across the state to complement the available literature. Assessments were released for public
review before the committee finalized them. The 2006 list includes 39 High species, 65 Moderate
species, and 89 Limited species. Additional information, including updated observations, will be added
to this website periodically, with revisions tracked and dated.
Definitions
The Inventory categorizes “invasive non-native plants that threaten wildlands” according to the
definitions below.
Plants were evaluated only if they invade California wildlands with native habitat values. The Inventory
does not include plants found solely in areas of human-caused disturbance such as roadsides and
cultivated agricultural fields.
•
•
•
Wildlands are public and private lands that support native ecosystems, including some
working landscapes such as grazed rangeland and active timberland.
Non-native plants are species introduced to California after European contact and as a direct
or indirect result of human activity.
Invasive non-native plants that threaten wildlands are plants that 1) are not native to, yet
can spread into, wildland ecosystems, and that also 2) displace native species, hybridize with
native species, alter biological communities, or alter ecosystem processes.

Cannon, Annie J. “Classifying the Stars.” The Universe of Stars. Edited by Harlow Shapeley and Cecilia
H. Payne. Cambridge, Mass.: Harvard Observatory, 1926. (1926)
Sunlight and starlight are composed of waves of various lengths, which the eye, even aided by a
telescope, is unable to separate. We must use more than a telescope. In order to sort out the
component colors, the light must be dispersed by a prism, or split up by some other means. For
instance, sunbeams passing through rain drops, are transformed into the myriad-tinted rainbow. The
familiar rainbow spanning the sky is Nature’s most glorious demonstration that light is composed of
many colors.
The very beginning of our knowledge of the nature of a star dates back to 1672, when Isaac Newton
gave to the world the results of his experiments on passing sunlight through a prism. To describe the
beautiful band of rainbow tints, produced when sunlight was dispersed by his three-cornered piece of
glass, he took from the Latin the word spectrum, meaning an appearance. The rainbow is the spectrum
of the Sun.
[…]
In 1814, more than a century after Newton, the spectrum of the Sun was obtained in such purity that an
amazing detail was seen and studied by the German optician, Fraunhofer. He saw that the multiple
spectral tings, ranging from delicate violet to deep red, were crossed by hundreds of fine dark lines. In
other words, there were narrow gaps in the spectrum where certain shades were wholly blotted out.
We must remember that the word spectrum is applied not only to sunlight, but also to the light of any
glowing substance when its rays are sorted out by a prism or a grating.

Bronowski, Jacob, and Millicent Selsam. Biography of an Atom. New York: Harper, 1965. (1965)
The birth began in a young star. A young star is a mass of hydrogen nuclei. Because the star is hot (about
thirteen million degrees at the center), the nuclei cannot hold on to their electrons. The electrons
wander around. The nuclei of hydrogen—that is, the protons—are moving about very fast too. From
time to time one proton runs headlong into another. When this happens, one of the protons loses its
electric charge and changes into a neutron. The pair then cling together as a single nucleus of heavy
hydrogen. This nucleus will in time capture another proton. Now there is a nucleus with two protons
and one neutron, called light helium. When two of these nuclei smash into each other, two protons are
expelled in the process. This creates a nucleus of helium with two protons and two neutrons.
This is the fundamental process of fusion by which the primitive hydrogen of the universe is built up into
a new basic material, helium. In this process, energy is given off in the form of heat and light that make
the stars shine. It is the first stage in the birth of the heavier atoms.

Walker, Jearl. “Amusement Park Physics.” Roundabout: Readings from the Amateur Scientist in
Scientific American. New York: Scientific American, 1985. (1985)
From “Amusement Park Physics: Thinking About Physics While Scared to Death (on a Falling Roller
Coaster)”
The rides in an amusement park not only are fun but also demonstrate principles of physics. Among
them are rotational dynamics and energy conversion. I have been exploring the rides at Geauga Lake
Amusement Park near Cleveland and have found that nearly every ride offers a memorable lesson.
To me, the scariest rides at the park are the roller coasters. The Big Dipper is similar to many of the
roller coasters that have thrilled passengers for most of this century. The cars are pulled by chain to the
top of the highest hill along the track, released from the chain as the front of the car begins its descent,
the un-powered cars have almost no speed and only a small acceleration. As more cars get onto the
downward slope the acceleration increases. It peaks when all the cars are headed downward. The peak
value is the product of the acceleration generated by gravity and the sine of the slope of the track. A
steeper descent generates a greater acceleration, but packing the coaster with heavier passengers does
not.
When the coaster reaches the bottom of the valley and starts up the next hill, there is an instant when
the cars are symmetrically distributed in the valley. The acceleration is zero. As more cars ascend the
coaster begins to slow, reaching its lowest speed just as it is symmetrically positioned at the top of the
hill.
A roller coaster functions by means of transfers of energy. When the chain hauls the cars to the top of
the first hill, it does work on the cars, endowing them with gravitational potential energy, the energy of
a body in a gravitational field with respect to the distance of the body from some reference level such as
the ground. As the cars descend into the first valley, much of the stored energy is transferred into kinetic
energy, the energy of motion.

From “Something in the Forest”
1980 New Year’s Day
Charles Monet was a loner. He was a Frenchman who lived by himself in a little wooden bungalow on
the private lands of the Nzoia Sugar Factory, a plantation in western Kenya that spread along the Nzoiz
Rover within sight of Mount Elgon, a huge, solitary, extinct volcano that rises to a height of fourteen
thousand feet near the edge of the Rift Valley. Monet’s history is a little obscure. As with so many
expatriates who end up in Africa, it is not clear what brought him there. Perhaps he had been in some
kind of trouble in France. Or perhaps he had been drawn to Kenya by the beauty of the country. He was
an amateur naturalist, fond of birds and animals but not of humanity in general. He was fifty-six years
old, of medium height and medium build with smooth, straight brown hair; a good-looking man. It
seems that his only close friends were women who lived in towns around the mountain, yet even they
could not recall much about him for the doctors who investigated his death. His job was to take care of
the sugar factory’s water-pumping machinery, which drew water from the Nzoia River and delivered it
to many miles of sugar-cane fields. They say that he spent most of his day inside the pump house by the
river as if it pleased him to watch and listen to the machines doing their work.

Hoose, Phillip. The Race to Save Lord God Bird. New York: Farrar, Straus and Giroux, 2004. (2004)
Read an Excerpt: The Race To Save The Lord God Bird
From THE RACE TO SAVE THE LORD GOD BIRD: INTRODUCTION
A BIRD OF THE SIXTH WAVE
To become extinct is the greatest tragedy in nature. Extinction means that all the members of an entire
species are dead; that an entire genetic family is gone, forever. Or, as ornithologist William Beebe put it,
"When the last individual of a race of living things breathes no more, another heaven and another earth
must pass before such a one can be again."
Some might argue that this doesn't seem so tragic. After all, according to scientists, 99 percent of all
species that have ever lived are now extinct. And there have already been at least five big waves of mass
extinction, caused by everything from meteorites to drought. The fifth and most recent wave, which
took place a mere 65 million years ago, destroyed the dinosaurs along with about two-thirds of all
animal species alive at that time. In other words, we've been through this before.
But the sixth wave, the one that's happening now, is different. For the first time, a single species, Homo
sapiens-humankind-is wiping out thousands of life forms by consuming and altering the earth's
resources. Humans now use up more than half of the world's fresh water and nearly half of everything
that's grown on land. The sixth wave isn't new; it started about twelve thousand years ago when
humans began clearing land to plant food crops. But our impact upon the earth is accelerating so rapidly
now that thousands of species are being lost every year. Each of these species belongs to a complicated
web of energy and activity called an ecosystem. Together, these webs connect the smallest mites to the
greatest trees.
This is a story about a species of the sixth wave, a species that was-and maybe still is-a bird of the deep
forest. It took only a century for Campephilus principalis, more commonly known as the Ivory-billed
Woodpecker, to slip from a flourishing life in the sunlit forest canopy to a marginal existence in the
shadow of extinction. Many species declined during that same century, but the Ivory-bill became the
singular object of a tug-of-war between those who destroyed and sold its habitat and a new breed of
scientists and conservationists dedicated to preserving species by saving habitat. In some ways, the
Ivory-bill was the first modern endangered species, in that some of the techniques used today to try to
save imperiled plants and animals were pioneered in the race to rescue this magnificent bird.
I say the Ivory-bill "maybe still is" a bird of the deep forest because some observers, including some very
good scientists, believe that a few Ivory-bills continue to exist. Since I first became interested in birds in
1975, I have read or heard dozens of reports that someone has just caught a fresh glimpse or heard the
unmistakable call of the Ivory-bill. Again and again, even the slimmest of rumors sends hopeful birdwatchers lunging for their boots, smearing mosquito repellent onto their arms, and bolting out the door
to look for it. Year after year they return with soggy boots, bug-bitten arms, and no evidence.
The Ivory-bill is a hard bird to give up on. It was one of the most impressive creatures ever seen in the
United States. Those who wrote about it-from John James Audubon to Theodore Roosevelt-were
astonished by its beauty and strength. They gave it names like "Lord God bird" and "Good God bird."
Fortunately, in 1935, when there were just a few left, four scientists from Cornell University took a
journey deep into a vast, primitive swamp and came back with a sound recording of the phantom's voice
and twelve seconds of film that showed the great bird in motion. It was a gift from, and for, the ages.
Cornell's image sparked a last-ditch effort led by the Audubon Society to save the Ivory-bill in its
wilderness home before it was too late. But others were equally intent on clearing and selling the trees
before the conservationists could rescue the species.
The race to save the Ivory-bill became an early round in what is now a worldwide struggle to save
endangered species. Humans challenged the Ivory-bill to adapt very quickly to rapidly shifting
circumstances, but as events unfolded, the humans who tried to rescue the bird had to change rapidly,
too. The Ivory-bill's saga-perhaps unfinished-continues to give us a chance to learn and adapt. As we
consider the native plants and animals around us, we can remind ourselves of the race to save the Lord
God bird and ask, "What can we do to protect them in their native habitats while they're still here with
us?"

History. 112.10 (Dec 2003). (2003)
Sung to the tune of “The Times They Are A-Changin’”:
Come gather ‘round, math phobes,
Wherever you roam
And admit that the cosmos
Around you has grown
And accept it that soon
You won’t know what’s worth knowin’
Until Einstein to you
Becomes clearer.
So you’d better start listenin’
Or you’ll drift cold and lone
For the cosmos is weird, gettin’ weirder.
—The Editors (with apologies to Bob Dylan)
Cosmology has always been weird. Worlds resting on the backs of turtles, matter and energy coming
into existence out of much less than thin air. And now, just when you’d gotten familiar, if not really
comfortable, with the idea of a big bang, along comes something new to worry about. A mysterious and
universal pressure pervades all of space and acts against the cosmic gravity that has tried to drag the
universe back together ever since the big bang. On top of that, “negative gravity” has forced the
expansion of the universe to accelerate exponentially, and cosmic gravity is losing the tug-of-war.
For these and similarly mind-warping ideas in twentieth-century physics, just blame Albert Einstein.
Einstein hardly ever set foot in the laboratory; he didn’t test phenomena or use elaborate equipment.
He was a theorist who perfected the “thought experiment,” in which you engage nature through your
imagination, inventing a situation or a model and then working out the consequences of some physical
principle.
If—as was the case for Einstein—a physicist’s model is intended to represent the entire universe, then
manipulating the model should be tantamount to manipulating the universe itself. Observers and
experimentalists can then go out and look for the phenomena predicted by that model. If the model is
flawed, or if the theorists make a mistake in their calculations, the observers will detect a mismatch
between the model’s predictions and the way things happen in the real universe. That’s the first cue to
try again, either by adjusting the old model or by creating a new one.

A photograph of a distant exploding star has given astronomers the first direct evidence that a
mysterious ''negative gravity'' force swept through and still pervades the universe, scientists announced
at a NASA news conference yesterday in Washington.
The Hubble Space Telescope by chance photographed the exploding star, the most distant ever
observed, in 1997. Scientists say subsequent detective work on the relative intensity of its light confirms
one of Einstein's conjectures about the universe: that all of space is bubbling with an invisible form of
energy that creates a mutual repulsion between objects normally attracted to each other by gravity.
Einstein himself thought the force, which he called the cosmological constant, was so strange that he
later repudiated his conjecture. But the idea gained theoretical support in 1998 with findings suggesting
that the expansion of the universe was accelerating and that the force accelerating the expansion,
negative gravity -- the manifestation of the cosmological constant -- overtook the force of gravity in the
last few billion years.
The new findings confirm that crucial part of the theory. And they rule out several competing
explanations.
Because the amount of negative gravity in any given volume should be minuscule, its effects would not
be felt in everyday life. But over vast distances involving huge volumes of space, the effect would be
powerful enough to push galaxies and clusters of galaxies apart from one another.
Exploding stars, or supernovas, like the one that turned up unexpectedly on a photograph made by the
Hubble telescope, can be excellent probes of those grand forces. The new observation is of a star that
exploded about 11 billion years ago, when the universe was a quarter of its present age and when,
scientists theorized, the cosmological constant, often called ''dark energy,'' was less powerful than
gravity, the opposite of what prevails today.
As a result, the expansion of the universe was slowing at that time. This meant that the star was closer
to earth when it exploded than it would have been if dark energy had dominated gravity then -- a fact
discernable in its brightness. Astronomers said it was twice as bright as it would have been under
competing theories about the universe.
A team led by Dr. Adam G. Riess, an astrophysist at the Space Telescope Science Institute in Baltimore
analyzed the data. Dr. Riess, who worked with Dr. Peter E. Nugent of Lawrence Berkeley National
Laboratory, said the measurement ''nails the existence of the dark energy.''
Dr. Michael S. Turner, an astrophysicist at the University of Chicago not involved in the work, called the
dark energy ''one of the most important discoveries in all of science.''
''If Einstein were around today, he would get another Nobel Prize for his prediction of repulsive gravity,''
Dr. Turner said.
He added that research would now shift to a hunt for the source of the energy and efforts to observe
many other distant supernovas to pin down the characteristics of the dark energy.
The universe is expanding as a legacy of its violent birth, which is believed to have occurred in a great
explosion or ''big bang'' roughly 14 billion years ago. Until recently, scientists were all but certain that
the gravitational attraction among the galaxies would slow the expansion.
But in 1998, two teams began presenting data on supernovas that they had observed as a way to
measure the change in the expansion rate over the last few billion years. They used a class of
supernovas that explode with nearly the same brightness each time, like bulbs of a known wattage. This
constancy enabled scientists to measure the speed at which the expansion of the universe had swept
these supernovas away: the dimmer they appeared from earth, the farther away they were.
Those observations revealed unexpectedly dim supernovas, suggesting that something, perhaps clouds
of cosmic dust, was obscuring them or that they were farther away than expected, perhaps driven away
by an anti-gravity force.
To find the explanation, astronomers tried to observe objects so distant that their light had been
traveling to Earth for billions of years.
''You need things that you can see across to the other side of the universe,'' Dr. Nugent said.
If cosmic dust were dimming this light, they reasoned, the objects would be dimmer the farther they
were from Earth. But if Einstein's explanation were correct, extremely distant supernovas should appear
to brighten relative to some standard, rather than continuing to dim.
Because they are so faint and are obscured by Earth's atmosphere, very distant supernova explosions
are rarely seen. But a break came in 1997 when teams led by Dr. Ronald L. Gilliland of the space
telescope institute and Dr. Mark Phillips of the Carnegie Institution of Washington made long-exposure
Hubble photographs of a tiny part of the sky. The pictures revealed a supernova in the distant gloom of
space.
A difficult and time-consuming analysis of light from the star showed that it was twice as bright as it
would have been if cosmic dust had been obscuring it or, as another hypothesis held, if supernovas had
somehow evolved steadily in brightness over the history of the cosmos.
The finding, said Dr. Saul Perlmutter, a physicist and supernova-hunter at the Berkeley laboratory not
involved in the work, was ''not very consistent with simple dust or evolution models.''
''That's the standout story here,'' Dr. Perlmutter said.
Cosmologists will have to cope with a universe that seems increasingly filled with mysterious stuff that
scientists cannot see and do not fully understand. The dark energy joins dark matter as an invisible
constituent of the cosmos. Dark matter's gravitational effects are known, and despite its invisibility it is
presumed to give the universe much of its mass.
Physicists will try to explain the source and exact nature of the dark energy. Dr. Turner said these
questions appeared to lie at the crossroads of several of the most important problems in physics.
''In 'The Graduate,' that guy told young Dustin Hoffman, 'plastics,' '' Dr. Turner said. ''My advice to the
next generation of particle physicists and astrophysicists: dark energy.''
Kane, Gordon. “The Mysteries of Mass.” Scientific American Special Edition. December 2005. (2005)
Physicists are hunting for an elusive particle that would reveal the presence of a new kind of field that
permeates all of reality. Finding that Higgs field will give us a more complete understanding about how
the universe works.
Most people think they know what mass is, but they understand only part of the story. For instance, an
elephant is clearly bulkier and weighs more than an ant. Even in the absence of gravity, the elephant
would have greater mass—it would be harder to push and set in motion. Obviously the elephant is more
massive because it is made of many more atoms than the ant is, but what determines the masses of the
individual atoms? What about the elementary particles that make up the atoms—what determines their
masses? Indeed, why do they even have mass?
We see that the problem of mass has two independent aspects. First, we need to learn how mass arises
at all. It turns out mass results from at least three different mechanisms, which I will describe below. A
key player in physicists’ tentative theories about mass is a new kind of field that permeates all of reality,
called the Higgs field. Elementary particle masses are thought to come about from the interaction with
the Higgs field. If the Higgs field exists, theory demands that it have an associated particle, the Higgs
boson. Using particle accelerators, scientists are now hunting for the Higgs.

(2007)
Steer Clear
Automakers are offering electronic stability control on more and more passenger vehicles to help
prevent them from sliding, veering off the road, or even rolling over. The technology is a product of an
ongoing evolution stemming from antilock brakes.
When a driver jams the brake pedal too hard, anti-lock hydraulic valves subtract brake pressure at a
given wheel so the wheel does not lock up. As these systems proliferated in the 1990s, manufacturers
tacked on traction-control valves that help a spinning drive wheel grip the road.
For stability control, engineers mounted more hydraulics that can apply pressure to any wheel, even if
the driver is not braking. When sensors indicate the car is sliding forward instead of turning or is turning
too sharply, the actuators momentarily brake certain wheels to correct the trajectory. “Going to
electronic stability control was a big step,” says Scott Dahl, director of chassis-control strategy at
supplier Robert Bosch in Farmington Hills, Michigan. “We had to add sensors that can determine what
the driver intends to do and compare that with what the car is actually doing.” Most systems also
petition the engine-control computer to reduce engine torque to dampen wayward movement.

Gibbs, W. Wayt. “Untangling the Roots of Cancer.” Scientific American Special Edition. June 2008.
(2008)
Recent evidence challenges long-held theories of how cells turn malignant—and suggests new ways to
stop tumors before they spread.
What causes cancer?
Tobacco smoke, most people would say. Probably too much alcohol, sunshine or grilled meat; infection
with cervical papillomaviruses; asbestos. All have strong links to cancer, certainly. But they cannot be
root causes. Much of the population is exposed to these carcinogens, yet only a tiny minority suffers
dangerous tumors as a consequence.
A cause, by definition, leads invariably to its effect. The immediate cause of cancer must be some
combination of insults and accidents that induces normal cells in a healthy human body to turn
malignant, growing like weeds and sprouting in unnatural places.
At this level, the cause of cancer is not entirely a mystery. In fact, a decade ago many geneticists were
confident that science was homing in on a final answer: cancer is the result of cumulative mutations
that alter specific locations in a cell’s DNA and thus change the particular proteins encoded by cancerrelated genes at those spots. The mutations affect two kinds of cancer genes. The first are called tumor
suppressors. They normally restrain cells’ ability to divide, and mutations permanently disable the
genes. The second variety, known as oncogenes, stimulate growth—in other words, cell division.
Mutations lock oncogenes into an active state. Some researchers still take it as axiomatic that such
growth-promoting changes to a small number of cancer genes are the initial event and root cause of
every human cancer.

Gawande, Atul. “The Cost Conundrum: Health Care Costs in McAllen, Texas.” The New Yorker. June 1,
2009. (2009)
It is spring in McAllen, Texas. The morning sun is warm. The streets are lined with palm trees and pickup
trucks. McAllen is in Hidalgo County, which has the lowest household income in the country, but it’s a
border town, and a thriving foreign-trade zone has kept the unemployment rate below ten percent.
McAllen calls itself the Square Dance Capital of the World. “Lonesome Dove” was set around here.
McAllen has another distinction, too: it is one of the most expensive health-care markets in the country.
Only Miami—which has much higher labor and living costs—spends more per person on health care. In
2006, Medicare spent fifteen thousand dollars per enrollee here, almost twice the national average. The
income per capita is twelve thousand dollars. In other words, Medicare spends three thousand dollars
more per person here than the average person earns.
The explosive trend in American medical costs seems to have occurred here in an especially intense
form. Our country’s health care is by far the most expensive in the world. In Washington, the aim of
health-care reform is not just to extend medical coverage to everybody but also to bring costs under
control. Spending on doctors, hospitals, drugs, and the like now consumes more than one of every six
dollars we earn. The financial burden has damaged the global competitiveness of American businesses
and bankrupted millions of families, even those with insurance. It’s also devouring our government.
“The greatest threat to America’s fiscal health is not Social Security,” President Barack Obama said in a
March speech at the White House. “It’s not the investments that we’ve made to rescue our economy
