Actor and singer David Cassidy recently revealed he has dementia, but what exactly does this term mean?

The 307-million-year-old Tully monster -- a marine animal with eyes like a hammerhead's and a pincer-like mouth -- was likely a spineless creature, a new study finds.

Some of the smallest known frogs in the world were recently discovered following a five-year survey in India.

(Phys.org)--Physicists are getting a little bit closer to answering one of the oldest and most basic questions of quantum theory: does the quantum state represent reality or just our knowledge of reality?

Treating multiple myeloma (MM) with myxoma virus (MYXV) eliminated a majority of malignant cells in preclinical studies, report investigators. Furthermore, introduction of MYXV had no impact on the bone marrow compartmen...

With the amazing ability to survey areas in complete darkness, night-vision cameras have revolutionized the security industry. But the materials and technology embodied in current cameras tend to degrade under temperatur...

Some people inherit a condition that elevates their cholesterol to an excessive degree, and no amount of diet or exercise can bring the numbers down. Researchers are developing and testing a new peptide that may lead to ...

Researchers recently discovered that an inhibitory brain receptor triggers synaptic pruning in adolescence. Drugs that selectively target these receptors, when administered during adolescence, can alter synapse number, w...

Current and former smokers suffering from illnesses like chronic lung or cardiovascular disease are more likely to use e-cigarettes, investigators report.

Memories are formed at structures in the brain known as dendritic spines, which communicate with other brain cells through 'synapses.' Researchers recently discovered that an inhibitory brain receptor triggers synaptic p...

There is a direct link between a person's attitude on social media and the likelihood that their dieting efforts will succeed. In fact, researchers have now determined that dieting success ­-- or failure -- can be predi...

Scientists present the smallest member of the CRISPR-Cas9 family developed to date and show that it can fit inside adeno-associated viruses and mutate blindness-causing genes

A group of researchers has come to a better understanding of how long-lived, antibody-producing plasma cells are maintained.

Instead of binge-watching one more episode of Game of Thrones or The Big Bang Theory, consider taking a few minutes to look at your cosmic neighborhood. You could be the one to discover a neighbor that has never been see...

Researchers have now found that physical forces exerted between cancer cells and the ECM are enough to drive a shape change necessary for metastasis. Those forces converge on an optimal stiffness that allows cancer cells...

Scientists have struggled to trace the specific biology behind diabetes-associated heart disease risk or find ways to intervene. Now, researchers have hunted down a possible culprit -- a protein called IRS-1, which is cr...

Testosterone treatment improved bone density and anemia for men over 65 with unequivocally low testosterone, a new study has concluded. However, testosterone treatment did not improve cognitive function, and it increased...

Among older adults with subthreshold depression (insufficient levels of depressive symptoms to meet diagnostic criteria), collaborative care compared with usual care resulted in an improvement in depressive symptoms afte...

Advanced prostate cancer and high blood cholesterol have long been known to be connected, but it has been a chicken-or-egg problem. Now a team of researchers has identified a cellular process that cancer cells hijack to ...

A new study suggests that researchers planning to use the CRISPR genome-editing system to produce designer gut bacteria may need to account for the dynamic evolution of the microbial immune system.

The location of an ectopic pregnancy can be determined quickly and easily with a simple, noninvasive physical examination technique used by osteopathic physicians. The method can be helpful in emergency situations, like ...

He abandoned the idea of a static, non-expanding universe in 1929—but some physicists are beginning to reconsider it --
