Sugar molecule links red meat consumption and elevated cancer risk in mice
While people who eat a lot of red meat are known to be at higher risk for certain cancers, other carnivores are not, prompting researchers at the University of California, San Diego School of Medicine to investigate the possible tumor-forming role of a sugar called Neu5Gc, which is naturally found in most mammals but not in humans.

Patient self-reporting version of 'blood pressure cuff' for dementia is reliable and valid
Patient self-reporting version of the Healthy Aging Brain Care Monitor -- a primary-care tool to measure cognitive, functional and psychological symptoms -- is user-friendly, reliable and valid, including being sensitive to symptom change, according to new Regenstrief Institute and Indiana University Center for Aging Research study.

CCNY study unveils new half-light half-matter quantum particles
Prospects of developing computing and communication technologies based on quantum properties of light and matter may have taken a major step forward thanks to research by City College of New York physicists led by Dr.

EPFL scientists have developed an extremely sensitive device that can detect life forms by sensing the slightest motion.

American cities are many times brighter than German counterparts
German cities emit several times less light per capita than comparably sized American cities.

A close look at blinking after facial transplantation
Recovery of blinking function is a critical but easily overlooked outcome after facial transplantation, according to a report in the January issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons.

For facial transplantation patients, blink assessment is essential
Face transplantation can dramatically enhance a patient's quality of life after severe facial trauma, but lack of attention to eyelid function and vision can leave patients with impaired vision, corneal exposure, eyelid retraction that occurs when the upper or lower eyelid pulls away from the eyeball, and other eyelid-related complications.

Researchers studied the impact of text message reminders for the second dose of influenza vaccine required for many young children to protect them against the virus.

A qubit candidate shines brighter
A team of researchers has taken a major step forward in effectively enhancing the fluorescent light emission of diamond nitrogen vacancy centers -- a key step to using the atom-sized defects in future quantum computers.

Lyme disease enhances spread of emerging tick infection
Mice that are already infected with the pathogen that causes Lyme disease appear to facilitate the spread of a lesser-known but emerging disease, babesiosis, into new areas.

Year of birth significantly changes impact of obesity-associated gene variant
Investigators working to unravel the impact of genetics versus environment on traits such as obesity may also need to consider a new factor: when individuals were born.

Estrogen worsens allergic reactions in mice
Estradiol, a type of estrogen, enhances the levels and activity in mice of an enzyme that drives life-threatening allergic reactions, according to NIAID researchers.

Team finds mechanism of toxin's inflammatory effect on lungs
University of Texas Health Science Center at San Antonio and Washington State University researchers documented a never-before-seen mechanism by which a bacterial toxin leads to severe inflammation in asthma and other acute and chronic pulmonary diseases.

What are the mechanisms of zooxanthella expulsion from coral?
Coral bleaching, which often results in the mass mortality of corals and in the collapse of coral reef ecosystems, has become an important issue around the world, with the number of coral reefs decreasing annually.

Protein ID'd as possible universal therapeutic target for many infections, including Ebola
A protein called GRP78 could be a universal therapeutic target for treating human diseases like brain cancer, Ebola, influenza, hepatitis and superbug bacteria such as methicillin-resistant Staphylococcus epidermidis and methicillin-resistant Staphylococcus aureus, according to a Virginia Commonwealth University-led preclinical study published this month in the Journal of Cellular Physiology.

Study: Atom-high steps halt oxidation of metal surfaces
Rust never sleeps. Whether a reference to the 1979 Neil Young album or a product designed to protect metal surfaces, the phrase invokes the idea that corrosion from oxidation -- the more general chemical name for rust and other reactions of metal with oxygen -- is an inevitable, persistent process.

Cancer-causing mutation discovered in 1982 finally target of clinical trials
