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.

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.

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.

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.

Antibodies given within one day of SHIV exposure can clear the virus

Scientists at the Oregon National Primate Research Center today revealed that infant rhesus macaques treated with antibodies within 24 hours of being exposed to SHIV, a chimeric simian virus that bears the HIV envelope protein, were completely cleared of the virus.
