The world's smallest species of snake, as thin as a spaghetti noodle and small enough to rest comfortably on a U.S. quarter, has been identified on the Caribbean island of Barbados.
The species, with adults averaging just under four inches in length, was discovered by Blair Hedges, an evolutionary biologist at Penn State. They list the discovery in the journal Zootaxa.
Hedges found the new snake -- a type of threadsnake -- in a tiny forest fragment on the eastern side of Barbados. He believes the species is rare because most of its potential habitat has been replaced by buildings and farms. "Habitat destruction is a major threat to biodiversity throughout the world," he said. "The Caribbean is particularly vulnerable because it contains an unusually high percentage of endangered species and, because these animals live on islands, they have nowhere to go when they lose their habitat."

Thid past week the “Klinikum rechts der Isar” of the Technical University of Munich saw the first transplant of complete arms after several years of preparatory work.
The patient's name was not released, and all that is known about the the identity of the arm donor is that it was a young person who died shortly before the surgery.
The patient, doing well given the circumstances, was operated on by the Clinic for Plastic Surgery and Hand Surgery (Director Prof. Hans-Günther Machens). The procedure, with a team of 40 people participating, was headed by PD Dr. Christoph Höhnke (Head of the transplant team, Senior Physician of the Clinic for Plastic Surgery and Hand Surgery) and Prof. Edgar Biemer (long-standing ex-board member of the plastic surgery division).

Rapid natural climate change was happening 12,700 years ago, write geoscientists who say they have proved for the first time that an extremely fast climate change happened in Western Europe long before man-made changes in the atmosphere, and is causatively associated with a sudden change in the wind systems.
Achim Brauer, Peter Dulski and Jörg Negendank, (emeritus Professor) from the GFZ German Research Centre for Geosciences, Gerald Haug from the DFG-Leibniz Center for Surface Processes and Climate Studies at the University of Potsdam and the ETH in Zurich, and Daniel Sigman from the Princeton University did the study.
The proof of an extreme cooling within a short number of years 12,700 years ago was attained in sediments of the volcanic lake “Meerfelder Maar” in the Eifel, Germany. The seasonally layered deposits allow to precisely determine the rate of climate change.

Everyone has pressure to perform and fit in at work; name any demographic and they will say it is tougher for them than it is for others. Is it equally hard for everyone and are some groups making it even harder on themselves?
Sociologists Marlese Durr of Wright State University and her co-author Adia Harvey Wingfield of Georgia State University at the the annual meeting of the American Sociological Association (ASA) say it is tougher for black women professionals than white women, lesbian women, all men, Hispanics, Latinos, Asians and even the French in America because black professionals engage in two types of "emotional performance" in the workplace that they say others do not: General etiquette and 'racialized' emotion maintenance.
And black women professionals place even more pressure on themselves, they state. Whether it's stressful, inauthentic or downright draining, Durr claims that emotional labor is "a crucial part of black women's self-presentation in work and social public spaces." These efforts to fit in can, in effect, make African American women feel isolated, alienated, and frustrated.

Ohio State University researchers have developed a new method of measuring school quality based on schools’ 'impact on learning' and their results say that summer vacations and parent incomes have more to do with low test scores than the quality of the schools.
Using this 'impact' measure, about three-quarters of the schools now considered “failing” because of their low test scores would no longer would be failing.
A school system measuring tool where everyone is above average even if they have poor test scores and where good test scores can still mean failure? Is that legitimate or is it just Outcome Based Education for education?

The recent suicide of Army scientist Bruce E. Ivins, shortly after being implicated, brought a likely end to the Anthrax scare of 2001 but, while information on this specific case remains sealed, the Global Terrorism Database at the University of Maryland is unclassified and available online to researchers. It contains more than 85,000 terror incidents since 1970. Hundreds of details associated with each incident are included to make the tool most useful to social scientists.
It shows that the 2001 anthrax attacks in the United States may be the only ones on record.
Bio-chemical terrorist attacks are very rare, according to Gary LaFree, director of the Global Terrorism Database at the University of Maryland, part of the U.S. Department of Homeland Security-funded National Consortium for the Study of Terrorism and Responses to Terrorism (START).

Male circumcision has been performed as far back as ancient Egypt, and the practice has continued through the ensuing centuries for religious, cultural and sociopolitical reasons.
Performing circumcision for potential health benefits gained momentum in the 19th century with the advent of anesthesia and the initial epidemiological studies demonstrating lower rates of venereal diseases in circumcised men. Recent studies have shown that circumcised men are at significantly lower risk of urinary tract infections and sexually transmitted infections such as syphilis and chancroid.
Additional studies point to lower risk of invasive penile carcinoma, gonorrhea and chlamydia (in female partners).

Mayo Clinic endocrinologist James Levine, M.D., Ph.D., has laid out some environment-changing innovations with a six-month study of a real-life office that was re-engineered to increase daily physical activity, a program called NEAT (non-exercise activity thermogenesis).
The study began in late 2007 and ended in 2008 at SALO, LLC, a Minneapolis-based financial staffing firm. Of the 45 employee volunteers involved in the scientific study, 18 were studied for weight loss and other changes.

Over the last decade, childhood obesity has grown into an epidemic, reflected in soaring rates of type 2 diabetes and recommendations that pediatricians check toddlers for elevated cholesterol.
What hasn't been as clear is how early to intervene.
A study presented at a pediatric research program on Friday suggested obesity prevention efforts should begin as early as age two, when children reach a "tipping point" in a progression that leads to obesity later in life.

The pinhole camera, a technique known since ancient times, has inspired a futuristic technology for lensless, three-dimensional imaging. Working at both the Advanced Light Source (ALS) at the U.S. Department of Energy's Lawrence Berkeley National Laboratory, and at FLASH, the free-electron laser in Hamburg, Germany, an international group of scientists has produced two of the brightest, sharpest x-ray holograms of microscopic objects ever made, thousands of times more efficiently than previous x-ray-holographic methods.
The x-ray hologram made at ALS beamline 9.0.1 was of Leonardo da Vinci's famous drawing "Vitruvian Man," a lithographic reproduction less than two micrometers (millionths of a meter, or microns) square, etched with an electron-beam nanowriter. The hologram required a five-second exposure and had a resolution of 50 nanometers (billionths of a meter).

On August 1, a total solar eclipse was visible in parts of Canada, northern Greenland, the Arctic, central Russia, Mongolia and China. The eclipse swept across Earth in a narrow path that began in Canada’s northern territory of Nunavut and ended in northern China’s Silk Road region.
Though the eclipse was not visible in most of North America, NASA TV and the Exploratorium made streaming video of the event available online. The following images are taken from that video, shot from the Xinjiang Uygur Autonomous Region in northwestern China near the Mongolian border. The sun appears differently in some of the images because of the different filters used to capture the event. Times listed are ET and approximate.

New knowledge points to the fact that a genetically induced lack of filaggrin, a key protein of the skin barrier, plays a decisive role in the origin of allergies.
In a large study on more than 3000 school-children scientists of the Helmholtz Zentrum München and the Technische Universität München found that about 8% of the German population carry variations of the filaggrin gene, which raise the risk to develop atopic dermatitis more than threefold. In addition, these genetic variations predispose to hay fever and asthma in those with atopic dermatitis.
