Whole genome sequencing of chimpanzee parasite reveals clues about human malaria

Understanding the origins of emerging diseases - as well as more established disease agents -- is critical to gauge future human infection risks and find new treatment and prevention approaches. This holds true for malaria, which kills more than 500,000 people a year. Symptoms, including severe anemia, pregnancy-associated malaria, and cerebral malaria, have been linked to the parasite's ability to cause infected red blood cells to bind to the inner lining of blood vessels.

Chronic lack of sleep lowers grades of students

Students who have a chronic lack of sleep have lower grades and find it harder to concentrate. Around a third of students do not feel well rested enough to be able to study properly.

New reference guide can help HIV care providers treat chronic pain

Recent studies suggest many individuals with HIV have chronic pain. Estimates range from 39 percent all the way to 85 percent. Chronic pain is an important comorbid condition in individuals with HIV, as it is common and causes substantial disability.

ORNL-NIST researchers reveal nondestructive way to observe nanoscale objects and processes

When lots of energy hits an atom, it can knock off electrons, making the atom extremely chemically reactive and initiating further destruction. That's why radiation is so dangerous. It's also why high-resolution imaging techniques that use energetic electron beams and X-rays can alter, even obliterate, the samples they explore. For example, monitoring battery dynamics using electron microscopy can introduce artifacts that interfere with electrochemical processes.

TGen investigators help track hypervirulent strep outbreak in southwestern U.S.

The Translational Genomics Research Institute (TGen) has helped state, local and tribal health officials identify an outbreak of "hypervirulent" strep bacteria in the American Southwest.

U of T researchers reveal how people have more control over object-based attention

Stage magicians are not the only ones who can distract the eye: a new cognitive psychology experiment demonstrates how all human beings have a built-in ability to stop paying attention to objects that are right in front of them.

Study identifies nerve cells and brain region behind innate fear response

The odor of bobcat urine, if you ever get a chance to take a whiff, is unforgettable -- like rotten meat combined with sweat, with something indescribably feral underlying it. To humans, it's just nose-wrinklingly disgusting.But to mice, it smells like one thing: fear.

Only few U.S. adults maintain healthy lifestyle, research finds

Only 2.7 percent of the U.S. adult population achieves all four of some basic behavioral characteristics that researchers say would constitute a "healthy lifestyle" and help protect against cardiovascular disease, a recent study concluded.

New research links active sun exposure habits of women with longer life expectancy

New research looks into the paradox that women who sunbathe are likely to live longer than those who avoid the sun, even though sunbathers are at an increased risk of developing skin cancer.

YAP protein plays vital role in development of human neural crest

The Hippo/YAP signalling pathway plays a crucial role when the cells of the neural crest - a structure that generates cell types such as bones and nerve tissue - specialise for a certain function in the human embryo and migrate to their target region within the body.

Researchers develop unique approach to track, label neural stem cells

An overwhelming number of researchers still struggle within the black hole of the effectiveness and safety of stem cell therapy for neurological diseases. While the complexity of understanding how neurons grow, connect and function has long been studied, it remains a mystery, one that graduate student Forrest Goodfellow in the University of Georgia Regenerative Bioscience Center is helping unravel.

Out-of-hospital birth rates continue to increase in U.S.

United States' out-of-hospital births increased to nearly 60,000 in 2014, continuing a decade-long increase. Data from the National Center for Health Statistics indicates that out-of-hospital births increased from 0.87% of US births in 2004 to 1.50% in 2014, an increase of 72%. Out-of-hospital birth rates increased for all race/ethnic groups, but most rapidly for non-Hispanic white women.

Moderate drinking not linked to longer life, study shows

Many people believe a glass of wine with dinner will help them live longer and healthier--but the scientific evidence is shaky at best, according to a new research analysis.

Sandia engineers aim to develop autonomous device to passively monitor mosquito-borne diseases

Mosquitoes are deadly efficient at spreading disease. Despite vaccines and efforts to eradicate the pesky insects, they continue to infect humans with feared diseases like Zika virus, malaria and West Nile virus.

Subcutaneous injection of raltegravir can protect against vaginal HIV transmission

Vaginal transmission accounts for the majority of new HIV infections worldwide. Forms of pre-exposure prophylaxis (PrEP) such as vaginal gels and vaginal rings designed to prevent HIV transmission have encountered poor efficacy in human trials due to problems with adherence.

Role of dietary restriction in lifespan extension

The role of dietary restriction in extending lifespan is the subject of research being conducted at the MDI Biological Laboratory in Bar Harbor, Maine, by visiting scientist Markus Schosserer, Ph.D., of the biotechnology department at the University of Natural Resources and Life Sciences, Vienna, in Austria.

Increased travel distance to cancer treatment facility affects receipt of RT

Increased travel distance to a cancer treatment facility negatively impacts the likelihood that patients with stage II/III rectal cancer will receive radiation therapy (RT) to treat their disease, according to a study analyzing 26,845 patient records from the National Cancer Data Base that was published in the March 2016 issue of International Journal of Radiation Oncology • Biology • Physics, the official scientific journal of the American Society for Radiation Oncology .
