What are the bare essentials of life, the indispensable ingredients required to produce a cell that can survive on its own? Can we describe the molecular anatomy of a cell, and understand how an entire organism functions as a system? Researchers are providing the first comprehensive picture of a minimal cell, based on an extensive quantitative study of the b […]

New cause for Alzheimer's disease?

Scientists have discovered that a precursor to nerve growth factor (pro-NGF) may play a pathogenic role in Alzheimer's disease.

Overcoming barriers for organic electronics

Electronic devices can't work well unless all of the transistors, or switches, within them allow electrical current to flow easily when they are turned on. Engineers have now determined why some transistors made of organic crystals don't perform well, yielding ideas about how to make them work better.

MRSA on the rise in hospital outpatients, new study finds; Seven-fold increase in potentially lethal superbug

The community-associated strain of the deadly superbug MRSA -- an infection-causing bacteria resistant to most common antibiotics -- poses a far greater health threat than previously known and is making its way into hospitals, according to a new study.

Exposure to both traffic, indoor pollutants puts some kids at higher risk for asthma later

New research presents strong evidence that the "synergistic" effect of early-life exposure to both outdoor traffic-related pollution and indoor endotoxin causes more harm to developing lungs than one or the other exposure alone.

Auditory illusion: How our brains can fill in the gaps to create continuous sound

It is relatively common for listeners to "hear" sounds that are not really there. In fact, it is the brain's ability to reconstruct fragmented sounds that allows us to successfully carry on a conversation in a noisy room.

Stem cells heal lungs of newborn animals: May lead to new treatments for lungs of premature babies

Scientists have demonstrated that stem cells protect and repair the lungs of newborn rats. The study finds that rats treated with stem cells ran twice as far, and had better survival rates. Currently, there is no treatment for the lungs of babies born too early. Scientists predict these results will lead to a new treatment for these babies within three years […]

New device enables early detection of cancerous skin tumors

Researchers are developing a new device that detects cancerous skin tumors, including melanomas that aren't visible to the naked eye. The OSPI instrument (Optical Spectro-Polarimetric Imaging) revealed new textures of lesions that have never been seen before. Dermatologists and plastic surgeons typically diagnose skin tumors by their appearance with the […]

Intensive land management leaves Europe without carbon sinks

A new calculation of Europe's greenhouse gas balance shows that emissions of methane and nitrous oxide tip the balance and eliminate Europe's terrestrial sink of greenhouse gases.

New tool for helping pediatric heart surgery

A team of researchers has developed a way to simulate blood flow on the computer to optimize surgical designs. It is the basis of a new tool that may help surgeons plan for a life-saving operation called the "Fontan" surgery, which is performed on babies born with severe congenital heart defects.
