A new study that assessed bodily responses suggests that standing up for your beliefs, expressing your opinions and demonstrating your core values can be a positive psychological experience, report researchers.

Being homeless puts people at greater risk of HIV infection than those with stable housing, but targeting services to reduce risk behaviors is often complicated by fuzzy definitions of homelessness, say authors of a new ...

Researchers have found that a form of magnetic resonance imaging (MRI) that non-invasively measures fat density in the liver corresponds with histological (microscopic tissue analyses) responses in patients with nonalcoh...

There are a couple strains of herpes so common that researchers estimate 90% of the human population have them. These strains, human herpes 6 and human herpes 7, usually do not cause severe symptoms when people acquire t...

A new study challenges the long-held belief that asbestos fibers cannot move through soil. The findings have important implications for current remediation strategies aimed at capping asbestos-laden soils to prevent huma...

New research links specific inherited genetic differences to an increased risk for eye (uveal) melanoma, a rare form of melanoma that arises from pigment cells that determine eye color. scientists report the first eviden...

Rheumatoid arthritis patients taking medications that inhibit interleukin-1beta, a molecule that stimulates the immune system, are 300 times more likely to experience invasive Group A Streptococcal infections than patien...

A child with absence epilepsy may be in the middle of doing something--she could be dancing, studying, talking--when all of a sudden she stares off into space for a few moments. Then, as quickly as she drifted off, the c...

Molecules derived from jellyfish may lead to a new generation of energetically efficient lasers that could improve everything from communications to medical procedures

It's unfair to question the right of runner Caster Semenya to compete in a sports world full of biological inequities, says Jaime Schultz

Researchers at Harvard Medical School have "radically rewritten" the genome of bacteria E. coli. The team has replaced 7 of its 64 codons (3-letter sequences which correspond usually to a single animo acid.) The lab, led...

By placing the order of two events into a quantum superposition, physicists have probed the nature of causality

Dementia strikes 47 million people worldwide. Yet scientists are still urgently trying to find why the disease affects some but not others. Among the findings from the latest research are that eating a large amount of fa...

A doctoral student and his adviser designed a tabletop particle detector they hope to make accessible to budding young engineering physicists. When Spencer Axani was an undergraduate physics student, his background in en...

Researchers have revealed, for the first time, the three-dimensional molecular 'map' of a protein that has been pinpointed as a driver of many types of cancers.

Swimming is as effective as walking to relieve pain and improve quality of life for patients with fibromyalgia, that experience chronic diffuse non-inflammatory pain in the musculoskeletal system deriving from malfunctio...

Inexpensive cloth masks worn by people who hope to reduce their exposure to air pollution vary widely in effectiveness and could be giving users a false sense of security, especially in highly polluted areas, results of ...

G proteins are molecular switches on the insides of cell membranes. They convey important signals to the inner workings of the cells. The associated receptors are targeted by all kinds of medications. Scientists are now ...

If a "zombeism" disease emerged, how might we actually stop it? Answering this kind of question can tell scientists a lot about how a genuine highly infectious condition might spread.

Biomaterials play a crucial role in the development of future high-performance materials. A naturally occurring example of such biomaterial, the mollusk shell, guides chemical replication processes in laboratories. Due t...

We might be one step closer to the vision of Internet-connected wireless implanted devices.
