Noninvasive brain control
MIT engineers have now developed the first light-sensitive molecule that enables neurons to be silenced noninvasively, using a light source outside the skull.

Father's ethnic background influences birthweight, study finds
A father's ethnic background can influence a child's birthweight, a new study has found.

Marine bacteria are natural source of chemical fire retardants
Researchers at the University of California, San Diego School of Medicine have discovered a widely distributed group of marine bacteria that produce compounds nearly identical to toxic man-made fire retardants.

Researchers estimate 5.8 million A&E visits occur after patients unable to see a GP
Researchers have estimated that in 2012-2013 there were 5.77 million A&E attendances in England that were preceded by an inability to get a timely GP appointment.

Lindau Nobel Laureate meeting opened
The 64th Lindau Nobel Laureate Meeting has begun: At Lindau, Germany, 37 Nobel laureates Exchange with more than 600 Young scientists from 80 countries.

NIH-funded researchers extend liver preservation for transplantation
Researchers have developed a new supercooling technique to increase the amount of time human organs could remain viable outside the body.

Single-pixel 'multiplex' captures elusive terahertz images
In an effort that advances attempts to generate images using terahertz light waves, researchers from Boston College, Duke University and the University of New Mexico report in Nature Photonics that they've developing a single-pixel 'multiplex' device that uses boutique metamaterials to capture images in the terahertz realm, which scientists say could play a crucial role in future medical and security imaging initiatives.

Massachusetts General-developed protocol could greatly extend preservation of donor livers
A system developed by investigators at the Massachusetts General Hospital Center for Engineering in Medicine allowed successful transplantation of rat livers after preservation for as long as four days, more than tripling the length of time organs currently can be preserved.

Missing protein explains link between obesity and diabetes
Scientists from the Institute of Molecular and Cell Biology, a research institute under the Agency for Science, Technology and Research, have discovered that obese individuals lack a protein that is essential for regulating blood glucose levels, causing them to face higher risks of developing diabetes.

Countdown to 2015 and beyond: Fulfilling the health agenda for women and children
The Lancet today publishes a new Review from the Countdown to 2015 collaboration, summarising results from the Countdown 2014 report, examining the data supporting evidence-based decisions in women's and children's health, describing elements of the Countdown process that might inform ongoing efforts to hold the world to account for progress, and listing concrete steps that can be taken now to ensure continued progress for women and children.

Bending the rules
For his doctoral dissertation in the Goldman Superconductivity Research Group at the University of Minnesota, Yu Chen, now a postdoctoral researcher at UC Santa Barbara, developed a novel way to fabricate superconducting nanocircuitry.

Improved method for isotope enrichment could secure a vital global commodity
Researchers at The University of Texas at Austin have devised a new method for enriching a group of the world's most expensive chemical commodities, stable isotopes, which are vital to medical imaging and nuclear power, as reported this week in the journal Nature Physics.

High CO2 levels cause warming in the tropics
Higher concentrations of carbon dioxide, CO2, in the atmosphere cause warming not only at high latitudes but also across tropical regions, according to new research by scientists at the University of Bristol, UK's Cabot Institute and their collaborators.

Researchers create quantum dots with single-atom precision
A team of physicists from the Paul-Drude-Institut für Festkörperelektronik in Berlin, Germany, NTT Basic Research Laboratories in Atsugi, Japan, and the US Naval Research Laboratory has used a scanning tunneling microscope to create quantum dots with identical, deterministic sizes.

Watching individual neurons respond to magnetic therapy
Duke researchers have developed a method to record an individual neuron's response to transcranial magnetic stimulation therapy.

Study finds Emperor penguin in peril
An international team of scientists studying Emperor penguin populations across Antarctica finds the iconic animals in danger of dramatic declines by the end of the century due to climate change.

A single gene separates aggressive and non-aggressive lymphatic system cancer
For a rare form of cancer called thymoma, researchers have discovered a single gene defining the difference between a fast-growing tumor requiring aggressive treatment and a slow-growing tumor that doesn't require extensive therapy.

Reconstructing the life history of a single cell
Scientists have created a way to rewind individual adult cells' life histories back to their origins in the embryo.
