Virus Caught in the Act of Infecting a Cell
Virus Caught in the Act of Infecting a Cell
AUSTIN, Texas — The detailed changes in the structure of a virus as it infects an  E. coli  bacterium have been observed for the first time, report researchers from The University of Texas at Austin and The University of Texas Health Science Center at Houston (UT Health) Medical School this week in  Science Express .

New qubit control bodes well for future of quantum computing
New qubit control bodes well for future of quantum computing
Yale University scientists have found a way to observe quantum information while preserving its integrity, an achievement that offers researchers greater control in the volatile realm of quantum mechanics and greatly improves the prospects of quantum computing. Quantum computers would be exponentially faster than the most powerful computers of today.

Life possible on extrasolar moons
Life possible on extrasolar moons
In their search for habitable worlds, astronomers have started to consider exomoons, or those likely orbiting planets outside the solar system. In a new study, a pair of researchers has found that exomoons are just as likely to support life as exoplanets. The research, conducted by Rory Barnes of the University of Washington and the NASA Astrobiology Institute and René Heller of Germany's Leibniz Institute for Astrophysics Potsdam , will appear in the January issue of Astrobiology.

Nursing gerbils unravel benefit of multiple mothers in collective mammals
In mammals such as rodents that raise their young as a group, infants will nurse from their mother as well as other females, a dynamic known as allosuckling. Ecologists have long hypothesized that allosuckling lets newborns stockpile antibodies to various diseases, but the experimental proof has been lacking until now.

A Clock Einstein Would Have Loved
A very special clock that can measure time on the basis of the mass of a single atomic or even subatomic particle holds promise not only for ultraprecise measurements of mass and time, but also for such exotic applications as testing Einstein's general theory of relativity, or the effects of gravity on antimatter.

Another Tool in the Nano Toolbox: Berkeley Lab Scientists Use Electron Beam to Manipulate Nanoparticles
Another Tool in the Nano Toolbox: Berkeley Lab Scientists Use Electron Beam to Manipulate Nanoparticles
Nanotechnology, the manipulation of matter at the atomic and molecular scale, holds great promise for everything from incredibly fast computers to chemical sensors that can sniff out cancer cells. But how does one go about building a device made of parts that are one-billionth of a meter in size? Over the years, scientists have developed tools for this microscopic handiwork.

First ‘plural’ towns and city outside London revealed
The research by the University's Centre on Dynamics of Ethnicity (CoDE) shows the towns of Slough and Luton and the city of Leicester are now 'plural'. Birmingham could join them in the next seven years. The team, who also find that 23 of London's 33 boroughs are plural, say towns and cities labelled by politicians as 'segregated' are in reality the most diverse.

IUD best treatment for heavy periods, major trial shows
The hormone-releasing Mirena coil intrauterine device (IUD) is a better treatment for heavy menstrual periods than other conventional medical approaches, according to results of a major clinical trial led by scientists from the Universities of Nottingham and Birmingham. The findings of the ECLIPSE study, funded by the National Institute for Health Research (NIHR), published online today (10 January 2012) in the New England Journal of Medicine, are widely expected to change standard clinical practice.

Co-infection and disease control
Becoming infected with one parasite could change your chances of becoming infected with another according to new University research. A new study led by the School of Biosciences analyses data from school-aged children in Tanzania infected with the most common forms of worms. It has found that infection by one parasitic species actually changes the risk of catching another, over and above other risk factors.

Penn Physicists Help Create ’Recipe Book’ for Building New Materials
By showing that tiny particles injected into a liquid crystal medium behave as predicted by existing mathematical theorems, physicists have opened the door for the creation of a host of new materials with properties that do not exist in nature.

Protective communities may reduce risk of drinking in teens
UNIVERSITY PARK, Pa. Living in a caring community may help curb teenage alcohol use, while hanging out with antisocial peers can have the opposite effect, according to Penn State researchers studying substance abuse patterns. The researchers evaluated how seven different categories of risk and protective factors predicted teen alcohol use.

Medical Center Research May Explain Why Obese People Have Higher Rates of Asthma
Findings suggest that therapies that increase leptin-signaling may relieve asthma in obese people New York, NY - A new study led by Columbia University Medical Center (CUMC) researchers has found that leptin, a hormone that plays a key role in energy metabolism, fertility, and bone mass, also regulates airway diameter.

Most effective treatment for common kidney disorder
Most effective treatment for common kidney disorder
The results of a pioneering UK-wide clinical trial that compared treatments for patients with a common type of kidney disease has found one to be significantly more effective. The results of the study, published online in The Lancet today [9 Jan], will be recommended to clinicians worldwide as the most effective approach to treating the condition.

First Alzheimer’s case has full diagnosis 106 years later
More than a hundred years after Alois Alzheimer identified Alzheimer's disease in a patient an analysis of that original patient's brain has revealed the genetic origin of their condition. The brain specimen tested was discovered in a university basement late last century after a search by rival teams of academics.

War was central to Europe’s first civilisation - contrary to popular belief
Research from the University of Sheffield has discovered that the ancient civilisation of Crete, known as Minoan, had strong martial traditions, contradicting the commonly held view of Minoans as a peace-loving people. The research, carried out by Barry Molloy of the University of Sheffield's Department of Archaeology, investigated the Bronze Age people of Crete, known by many as the Minoans, who created the very first complex urban civilisation in Europe.

High salt intake linked to social inequalities
People from low socio-economic positions in Britain eat more salt than the well off, irrespective of where they live, states a paper led by Warwick Medical School publishedin the BMJ Open journal. The research was carried out by the World Health Organization Collaborating Centre for Nutrition, based in the Division of Mental Health & Wellbeing of Warwick Medical School at the University of Warwick.

New drug for bipolar disorder may offer fewer side effects
A drug for bipolar disorder that works like lithium, the most common and effective treatment for the condition, but without lithium's toxicity and problem side-effects has been identified by Oxford University researchers in a study in mice. A drug that mimics the effect of lithium but without its side-effects would be a great improvement for patients, and has long been sought after.

Stressed-out cells halt protein synthesis
Stressed-out cells halt protein synthesis
Cells experience stress in multiple ways. Temperature shifts, mis-folded proteins and oxidative damage can all cause cellular stress. But whatever the form of the stress, all cells quickly stop making proteins when under pressure. A new Cornell study unravels how cells rapidly stall protein synthesis during stress and then resume their protein-making activities once the stress has passed.

First "Bone" of the Milky Way Identified
Long Beach, CA - Our Milky Way is a spiral galaxy - a pinwheel-shaped collection of stars, gas and dust. It has a central bar and two major spiral arms that wrap around its disk. Since we view the Milky Way from the inside, its exact structure is difficult to determine. Astronomers have identified a new structure in the Milky Way: a long tendril of dust and gas that they are calling a "bone." "This is the first time we've seen such a delicate piece of the galactic skeleton," says lead author Alyssa Goodman of the Harvard-Smithsonian Center for Astrophysics (CfA).
