Scientists Flesh Out Fossilized Tissues from Mummified Dinosaur
June 30, 2009
Mineralized skin samples suggest that the plant-eating hadrosaur may have been larger and faster than thought.
Being More Infantile May Have Led to Bigger Brains
For decades scientists have noted that mature humans physically resemble immature chimps—we, too, have small jaws, flat faces and sparse body hair. The retention of juvenile features, called neoteny in evolutionary biology, is especially apparent in domesticated animals—thanks to human preferences, many dog breeds have puppy features such as floppy ears, short snouts and large eyes. Now genetic evidence suggests that neoteny could help explain why humans are so radically different from chimpanzees, even though both species share most of the same genes and split apart only about six million years ago, a short time in evolutionary terms.
Scientists Flesh Out Fossilized Tissues from Mummified Dinosaur
June 30, 2009
Earlier this week scientists studying fossilized teeth from a hadrosaur revealed how the duck-billed dinosaur chewed plants for food. Now another team, analyzing what may be the most intact dinosaur mummy discovered yet, report fresh details about the skin of a hadrosaur nicknamed Dakota, which might have been bigger and moved more quickly than previously thought.
Are Midwestern Earthquake Faults Shutting Down?
The center of the U.S. saw earthquakes two centuries ago that were powerful enough to briefly reverse the flow of the Mississippi River. But unlike Californians, who must live with the specter of “the big one,” Midwesterners may have already seen the last of them. New research suggests the crack in the earth behind the Mississippi Valley events may actually be shutting down. If so, geoscientists will need to rethink how earthquakes work.
May 19, 2009
Submicroscopic techniques that could kill cancer or mend weak hearts will only be used if they target the right cells and leave others unharmed. After years of development, Robert Langer at the Massachusetts Institute of Technology and his colleagues will soon begin clinical trials of "magic bullets" that employ nanotechnology to deliver drugs only where they are needed.
High Content Is King
May 19, 2009
A yellow robot arm moves with a combination of inhuman speed and delicate grace, loading a microscope with a plate split up into 1,536 wells, each filled with ovary cells from Chinese hamsters. Here the classic image of scientists peering into microscopes to laboriously scan slide after slide is gone. In an instant, the automated microscope at Merck Research Laboratories in North Wales, Penn., digitally images all of the specimens simultaneously.
Does Daylight Saving Time Conserve Energy?
March 5, 2009
Starting this month, roughly one quarter of the world’s population will lose sleep and gain sunlight as they set their clocks ahead for daylight saving. People may think that with the time shift, they are conserving electricity otherwise spent on lighting. But recent studies have cast doubt on the energy argument—some research has even found that it ultimately leads to greater power use.
How Teenagers Find Themselves
February 6, 2009
Teens are notoriously self-conscious. Now brain-imaging experiments are revealing how this adolescent predilection might be the result of changes in brain anatomy linked with the self, and the findings may hint at how the sense of self develops in the brain.
Quantum Entanglement Benefits Exist after Links Are Broken
January 22, 2009
“Spooky action at a distance” is how Albert Einstein famously derided the concept of quantum entanglement—where objects can become linked and instantaneously influence one another regardless of distance. Now researchers suggest that this spooky action in a way might work even beyond the grave, with its effects felt after the link between objects is broken.
Does Dark Matter Encircle Earth?
January 15, 2009
Astronomers only found out about dark matter by inferring its presence from the gravity it exerts—notably, it keeps spinning galaxies from flying apart. Rather than peering at distant galaxies to study it, though, astronomers might want to look closer to home: dark matter could be exerting measurable effects in our own solar system.
Do White Blood Cells Make Cancer Deadly?
January 12, 2009
The leading cause of death in cancer is metastasis—tumors are generally treatable as long as they have not moved to vital organs. So if the research reveals that such hybrids help cancer spread, it could open up new avenues to fighting cancer. As Pawelek puts it: “You have to know how metastasis starts to properly fight it.”
Reaping a Sad Harvest: A "Narcotic Farm" That Tried to Grow Recovery

Mammoth Sequences: A Hunt for DNA from the Extinct Titans of the Klondike
After revving up with a roar, a core drill designed to punch holes in concrete begins digging into ice more than 100,000 years old. Here in the Klondike, the drill serves as a kind of gas-powered, handheld time machine, bringing up frozen earth from the Pleistocene, when mammoths and other megafauna once ruled. In a land where miners still hunt for gold, paleomammalogist Ross Mac–Phee of the American Museum of Natural History in New York City and his colleagues seek a different kind of treasure—DNA from extinct titans.

Whatever Happened to the Pioneer Spacecraft?
May 8, 2008
The velocities of Pioneer 10 and 11, now speeding out of the solar system, are mysteriously changing, as if an extra force from the sun were tugging at them. Explanations have ranged from gas leaks and observational error to modified theories of gravity. Now Jet Propulsion Laboratory astronomer John Anderson and his colleagues, who helped to uncover the Pioneer anomaly, have found similar unexpected changes with four spacecraft that have flown by Earthï¿1⁄2namely, Galileo, the Near-Earth Asteroid Rendezvous (NEAR) mission, Cassini and Rosetta.
A Bug's Sex Life: A Q&A with Isabella Rossellini
May 5, 2008
Isabella Rossellini, well known as a supermodel and movie star, is now making short films for mobile devices that illustrate the sex lives of dragonflies, earthworms and other creatures. But they are not like standard nature shows. In these films, which she researched with the help of Wildlife Conservation Society experts, she not only details unusual aspects of the critters' biology but also dresses up as them and mimics sex with paper cutouts.

Humans Marrying Robots? A Q&A with David Levy
February 19, 2008
Q: If people fall in love with robots, aren't they just falling in love with an algorithm?
A: It's not that people will fall in love with an algorithm, but that people will fall in love with a convincing simulation of a human being, and convincing simulations can have a remarkable effect on people.

Glow for the Dark
November 19, 2007
In 1868 Swedish physicist Anders ï¿1⁄2ngstrï¿1⁄2m discovered that the sky always has a slight glow to it. The light emanates from molecules excited by sunlight or cosmic rays in the upper atmosphere. At night, the amount of airglow is comparable to the light from the full moon spread over the entire sky. But because most of it lies in the short-wave infrared range, the light remains largely invisibleï¿1⁄2at least to human eyes. Researchers have now devised a camera that could effectively detect this glow to see in the dark better than ever before.

A Stroke for Stem Cells
January 14, 2007
The first stem cell therapy targeting a major brain disorder, chronic stroke, could begin clinical trials this year if the U.S. Food and Drug Administration approves the request filed in December by stem cell firm ReNeuron in Guildford, England. This latest treatment suggests stem cell therapies are growing not only in number but in ambition.
Five New Year's Resolutions You Owe Yourself
January 8, 2007
On New Year's day more than a few of us resolved to change our lives, or at least our more self-indulgent habits. On the hunch that all things flow from good health, Scientific American has based this year's list of five resolutions on the advice of health professionals and the scientific literature. Whatever your goals, we'll help you understand why there's hardly anything you could choose to do that could have a bigger impact on your quality of life.
Pollution in Solution
December 16, 2006
DNA that makes germs resistant against medicines may increasingly be polluting water, from rivers all the way to the faucet. Scientists caution these contaminants, if not cleansed, could exacerbate the growing problem of drug resistance among potentially harmful microbes. The genes join a long list of contaminants being found in water, posing a challenge for devising an effective means of treatment.
Human, Sea Slug Brains Share Genes for Alzheimer's and Parkinson's
December 29, 2006
The ancestors of humans and sea slugs diverged more than a half billion years ago, but scientists have now unexpectedly found genes that are remarkably similar in the brains of both. These findings could help shed light on the evolution of the brain in the animal kingdom and the mechanisms of human disorders such as Alzheimer's disease.
Children Took a Toll in Pre-Industrial Societies, May Have Driven Evolution of Menopause
December 29, 2006
Before the advent of birth control, industrialized agriculture and day care, women and men who chose to have very large families faced an early grave when compared to their less fecund peers. In the largest and most comprehensive study of its kind, Dustin Penn of the Konrad Lorenz Institute for Ethology in Austria and Ken Smith of the University of Utah studied the records of 21,684 Mormon couples who wed between 1860 and 1895 in order to examine the trade-off between family size and survival.

Citizens thoughtfully weigh the pros and cons of arguments before choosing their leaders--or so political science has traditionally assumed. Now experiments and computer models are challenging this notion, suggesting that voters tend to make emotional decisions that they rationalize afterward.
October 26, 2006
A method that can generate human embryonic stem cells without harming embryos? In August biotechnology firm Advanced Cell Technology (ACT) in Worcester, Mass., claimed it had developed just such a procedure. The company touted it as a way around the firestorm of controversy surrounding the conventional technique for growing these cells, which destroys human embryos. Most researchers find the method intriguing, because it might lead to new and maybe better stem cell lines. But several also argue that it raises fresh dilemmas.
Old MacDonald's Pharm
In the milk of 30 genetically modified goats on GTC Biotherapeutics's farm in Charlton, Mass., is a drug that can literally make your blood flow--the human protein antithrombin, which inhibits clotting. In a dramatic reversal, after European reg-ulators rejected this drug (called ATryn), they now look ready to approve it later this year. The ruling would make ATryn the first human protein made by a transgenic animal for commercial production.
Not So Super
The drug's inventors called their creation a "superantibody." They hoped that it would be capable of activating immune cells other antibody drugs could not on their own. The moniker for the compound, targeted at autoimmune disease or leukemia, was TGN1412, made by TeGenero, based in Wï¿1⁄21⁄2rzburg, Germany. On March 13 six previously healthy volunteers given the antibody in a routine test of its safety were sent to intensive care.
Carbon nanotubes would make ideal connecting wires in advanced circuits if not for the painstaking effort required to line up each tiny, sticky, floppy strand. Now scientists have found that crystalline sapphire can automatically help guide nanotubes into the patterns needed to build transistors and to make flexible electronics.
Going to Bat
Bats are creatures of the night that are commonly held in fear. At first glance, those fears might seem to have some medical justification. Long known as vectors for rabies, bats may be the origin of some of the most deadly emerging viruses, including SARS, Ebola, Nipah, Hendra and Marburg. Instead of demonizing bats, however, research shows the real culprit behind these outbreaks could be human error.
The transistor, dating from 1947, has shrunk from a kludgy, half-inch-high contraption to a device whose components boast dimensions a few hundreds of atoms in length. Batteries, on the other hand, have improved how much power they deliver at roughly one fiftieth of that pace.
Bell Laboratories, which built the first transistor, has now become involved with the reinvention of the battery. The goal is to apply the techniques used for manufacturing transistors to mass-produce a battery that can be built in with the other circuitry on a chip.
Polar Satellite Freeze
January 22, 2006
The long-range weather forecasts that warned of where Hurricane Katrina would strike depended on data from polar satellites. They capture not only details over the Arctic and Antarctic but also virtually every point on the planet's surface as the world turns under them. Now the replacements for the aging U.S. military and civilian fleet are in jeopardy. The program is as much as $3 billion over budget, and the launch of the first replacement satellite is as many as three years behind schedule.
Un-Killing the Messenger
For a cell to make proteins, the nucleus first has to issue instructions. Once these genetic memos outlive their usefulness, they end up deactivated in repositories known as processing bodies. Research now suggests that these P-bodies are less like junkyards and more like office centers, where messages are amassed, silenced and reactivated.
Baby to Brain
October 31, 2005
Mothers could literally always have their kids on their minds. Researchers find that in mice, cells from fetuses can migrate into a mother's brain and apparently develop into nervous system cells.
Transistor Flow Control
At the heart of modern electronics are transistors, which act like valves to direct the flow of electrons. Now researchers at the University of California at Berkeley have created the first transistors that electrically control molecules instead. By connecting them to microscopic test tubes and petri dishes, these nanoscale transistors could lead to labs-on-a-chip that work without moving parts.
Chatting Up Cells
September 19, 2005
Stem cells can transform into whatever cell the body tells them to. Unfortunately, scientists have yet to master that particular gift of gab. But investigators at Stanford University may soon crack the language with tiny "chat rooms" for stem cells.

Fans of the spacetime continuum can now uncover gravitational ripples at their desks thanks to the February launch of Einstein@Home. The project is one of the latest of at least 60 "@home" projects now on the Internet, in which personal-computer users can donate spare processor power to help solve scientific problems. And no need to choose one mission over another: @home software can now multitask, and enough microchip muscle exists to handle many more distributed-computing projects.

Before the advent of electricity, the first computers were mechanical, with the Difference Engine invented by Charles Babbage tackling logarithms and trigonometry 150 years ago. Now advanced quantum computers might go back to mechanical roots, using rows of nanometer-scale bars as moving parts.
Back to Square One
February 28, 2005
After 15 years, cold fusion got a second chance at legitimacy from the U.S. Department of Energy, often seen by cold fusion advocates as their greatest enemy. This rematch, many hoped, would vindicate the field or kill it once and for all. Instead history repeated itself, with a verdict that evidence remained inconclusive.
Hungry for Dino Meat
Early mammals conjure up images of rat- or shrew-size creatures that skulked in the shadows of dinosaurs, trying to avoid being ripped limb from limb by the terrible lizards. Now it seems that the hunted sometimes became the hunter. Newfound fossils reveal a baby dinosaur inside a mammal's gut -- the first direct evidence of such predation.

In A.D. 79 Mount Vesuvius erupted, annihilating the cities of Pompeii and Herculaneum and killing thousands who did not evacuate in time. To avert a similar fate for present-day Naples, which lies six miles west of the still active Vesuvius, as well as for the cities near volatile Mount Etna in Sicily, a novel laser system could soon forecast volcanic eruptions up to months in advance.
In February the Nipah virus reemerged, killing 35 people in Bangladesh in two outbreaks. Although the number of victims is small, the deaths have health officials worried. Unlike its first appearance in Malaysia in September 1998, the virus in Bangladesh may have jumped from person to person, raising concern about its ability to spread farther and faster.
