Stem Cells The Real Culprits In Cancer

After more than 30 years of declared war on cancer, a few important victories can be claimed, such as 85 percent survival rates for some childhood cancers whose diagnoses once represented a death sentence. In other malignancies, new drugs are able to at least hold the disease at bay, making it a condition with which a patient can live. In 2001, for example, Gleevec was approved for the treatment of chronic myelogenous leukemia (CML)....

The Neglect Of Mental Illness Exacts A Huge Toll Human And Economic

Mental health care is one of the biggest unmet needs of our time. Nearly one in two people in the U.S. will suffer from depression, anxiety disorders or another mental health ailment at some point in their life, and about one in 17 Americans currently has a serious mental illness. Young people are especially prone to these troubles. Yet millions of people living with these conditions do not receive the care they require....

The Strange Topology That Is Reshaping Physics

Charles Kane never thought he would be cavorting with topologists. “I don’t think like a mathematician,” admits Kane, a theoretical physicist who has tended to focus on tangible problems about solid materials. He is not alone. Physicists have typically paid little attention to topology—the mathematical study of shapes and their arrangement in space. But now Kane and other physicists are flocking to the field. In the past decade, they have found that topology provides unique insight into the physics of materials, such as how some insulators can sneakily conduct electricity along a single-atom layer on their surfaces....

Trial Sans Error How Pharma Funded Research Cherry Picks Positive Results Excerpt

Excerpt from Bad Pharma: How Drug Companies Mislead Doctors and Harm Patients, by Ben Goldacre. Published by Faber and Faber, Inc. © 2013 Ben Goldacre. Excerpted with permission from the publisher. All Rights Reserved. Before we get going, we need to establish one thing beyond any doubt: industry-funded trials are more likely to produce a positive, flattering result than independently funded trials. This is our core premise, and you’re about to read a very short chapter, because this is one of the most well-documented phenomena in the growing field of “research about research”....

Undersea Telescopes Scan The Sky From Below

Suspended near the bottom of the Mediterranean Sea off France and Italy, 126 football-sized glass spheres are already using the ocean itself as an instrument to search for signals from dark matter, supernovae and neutron star collisions. These are the first of many such globes deployed for a project called the Cubic Kilometer Neutrino Telescope, or KM3NeT. Its target, neutrinos, are fundamental particles that have no electrical charge and almost no mass....

Watch Live Today A Bold New View Of Gravity

In stories about the universe gravity plays a starring role. It is the force that best explains not only the motions of the planets, stars and galaxies, but also their origins and evolution—how order coalesced from the chaos of the primordial cosmos. Yet for all of gravity’s importance, physicists’ understanding of it is in many respects woefully incomplete. After famously watching an apple fall from a tree, Isaac Newton recognized gravity as a fundamental force acting on all things, yet he failed to explain its origins....

Windows On The Mind Video Supplement

A close-up of a computer-simulated human eye during fixation, with an inset view of the central retina. Although the eye is voluntarily “fixated” on the edge of a figure, it nevertheless makes tiny eye movements with distinct characteristics. The moving position of one point of the figure is displayed as a line on the retina in the inset. This plot reveals three types of fixational eye movements: fast microsaccades, slow drift, and oscillatory tremor, all of which move the stimulus by different amounts across the photoreceptor cells of the retina....

Women S Exposure To Chemicals May Explain Unexpected Breast Cancer

Deep in a laboratory freezer, 100,000 vials of blood have been frozen for the better part of five decades. For scientist Barbara Cohn, it’s a treasure trove. Collected from more than 15,000 San Francisco Bay Area women after they gave birth in the 1960s, each vial of blood holds a woman’s lifetime of secrets. Scientists say these vials could help them unravel one of the most enduring medical mysteries: Why do some women, with no family history, develop breast cancer?...

A Dolphin S Tale How Researchers Gave One Bottlenose A Prosthetic Tail

In December 2005, when winter the bottlenose dolphin was just a few months old, she was swimming with her mother in Mosquito Lagoon, along central Florida’s Atlantic coast. Somehow she got herself tangled in a crab trap. An eagle-eyed fisherman spotted her struggling and called in a wildlife rescue team. The volunteers gently positioned the dolphin on a stretcher, carried her out of the water and drove her across the state to the Clearwater Marine Aquarium....

A Healthy Hate For Lovegrass

From Ensia (find the original story here); reprinted with permission. Dryland rancher Vivan Mawhinney spends a lot of his time thinking about invasive African lovegrass. As he drives around his property in Australia’s Bega Valley, halfway between Melbourne and Sydney, he’s continually planning how and when he’ll move his Angus cows and Merino ewes around so that he can beat the spread of the densely tufted weed. Mawhinney’s property covers 600 hectares (1,500 acres) of gently undulating country, 20 kilometers (12 miles) east of a line of blue hills that mark the edge of the Great Dividing Range....

Artificial Intelligence That Performs Real Magic Tricks Video

The perfect sleight is a flawlessly coordinated act of deception. Magicians dedicate hours to bullying their fingers into precise positions and years mastering the art of misdirection. The best illusionists spend a lifetime honing their prestidigitations. Now, there’s a computer can do it, too—all in a matter of seconds. Yesterday programmers at Queen Mary University of London unveiled a system that uses artificial intelligence to perform magic tricks. The program not only calculates probabilities—it can capture every potential outcome of most card tricks—the system also evaluates how human spectators will perceive its performances, based on behavioral and cognitive studies....

Avian Cooperation Rooks Work Together To Solve Puzzle For Food

Birds of a feather don’t just flock together—they also work together to obtain food. Recent research makes rooks the first nonprimates observed to successfully cooperate to retrieve a food-laden platform, according to a June 22 study in the journal Proceedings of the Royal Society B: Biological Sciences. Scientists at the University of Cambridge tested the rooks, which are Eurasian members of the crow family, by placing dishes of food on a platform out of reach of a bird enclosure....

Climate Change After Bali Extended Version

Last December’s agreement in Bali to launch a two-year negotiation on climate change was good news, a rare example of international cooperation in a world seemingly stuck in a spiral of conflict. Cynics might note that the only accomplishment was an agreement to talk some more, and their cynicism may yet be confirmed. Nevertheless, the growing understanding that serious climate-control measures are feasible at modest cost is welcome. The arithmetic is becoming clearer....

How Lab Rats Are Changing Our View Of Obesity

Obesity stems primarily from the overconsumption of food paired with insufficient exercise. But this elementary formula cannot explain how quickly the obesity epidemic has spread globally in the past several decades nor why more than one third of adults in the U.S. are now obese. Many researchers believe that a more complex mix of environmental exposures, lifestyle, genetics and the microbiome’s makeup help explain that phenomenon. And a growing body of work suggests that exposure to certain chemicals—found in nature as well as industry—may play an essential role by driving the body to produce and store surplus fat in its tissues....

In Search Of Satisfaction

In 1944 researchers recognized that millions of people were at risk of famine as a result of the ravages of World War II. To investigate the impact of food deprivation on the human body, 36 healthy men volunteered to endure a six-month semistarvation diet and be observed by scientists and doctors. The result? Hunger made the men obsessed with food. They would dream and fantasize about eating. They reported fatigue, irritability and depression, along with decreased concentration, comprehension and judgment....
