UNLESS creatures such as yeti and Bigfoot turn out to be real, the only kind of human in the modern world is Homo sapiens. But that is only recently true. For most of Homo sapiens's 200,000-year history, it shared the pl...

The first-ever detection of gravitational waves, which scientists could announce Thursday, would open a new window on the universe and its most violent phenomena.

If there's dark matter hiding in our sun, it could be giving off dark photons. The best part is we already have a detector in space that could spot them

Patterns of episodes of diverticulitis before surgery, and factors associated with earlier interventions using inpatient, outpatient, and antibiotic prescription claims, have all been examined by a group of researchers.

Atomic clock experts from the Physikalisch-Technische Bundesanstalt (PTB) are the first research group in the world to have built an optical single-ion clock which attains an accuracy which had only been predicted theore...

In a world-first, researchers have performed cardiac MRI imaging using a 7T MRI scanner in a patient-based study. 7T MRI imaging is a powerful new technology that allows high resolution images of the beating heart, and h...

In one of the first efforts to date to apply nanotechnology to targeted cancer therapeutics, researchers have created a nanoparticle formulation of a cancer drug that is both effective and nontoxic -- qualities harder to...

Poor physical fitness in middle age may be linked to a smaller brain size 20 years later, according to a new study.

Lynn Cominsky, physicist with the LIGO collaboration, will be answering your questions about LIGO's Feb. 11 announcement live. Tweet questions to @physicscentral #LIGOlive or comment here.

A study of cadavers reveals a dramatic decrease of vitamin B12 in the brain across the ages but also among young people with autism and schizophrenia.

Statin drugs interact with a gap junction protein called GJC3 that releases ATP, a major signaling molecule for inflammation in the body, new research shows. This discovery provides a significant new target in the search...

Three adult men and a young adolescent of unknown gender buried in cemeteries outside Rome were likely migrants to the city, their teeth reveal.

Researchers have devised several lipid-based diets aimed at slowing down progression and relieving symptoms of Alzheimer's disease (AD). It is generally accepted that lifestyle and particularly dietary habits influence m...

Paleontologists using 3D laser scanning to study fossils of extinct Trilobites from the Cambrian era have been able to deduce how these horseshoe crab-like animals attacked prey .

Technische Bundesanstalt (PTB) are the first research group in the world to have built an optical single-ion clock which attains an accuracy which had only been predicted theoretically so far. As early as 1981, Hans Dehm...

Just as a photographer needs a camera with a split-second shutter speed to capture rapid motion, scientists looking at the behavior of tiny materials need special instruments with the capacity to see changes that happen ...

Previous research has established a link between genetic mutations in the BRCA1 and BRCA2 genes to an increased risk of developing ovarian, fallopian tube or peritoneal cancer in women. A recent publication documents the...

The age at which an adolescent begins using marijuana may affect typical brain development, according to researchers. Scientists describe how marijuana use, and the age at which use is initiated, may adversely alter brai...

New insight has been gained into how the brains of drug addicts may be wired differently. The findings show that while drug users have very strong motivation to seek out 'rewards,' they exhibit an impaired ability to adj...

A type of cancer found primarily in children can grow only when signaled to do so by other nearby cells that are noncancerous, new research shows. The study contributes to a growing body of research that implicates the e...

A device that can do the functional equivalent of high-throughput compound screening on an ultra-miniaturized scale has been developed by researchers.

Following an acute heart attack, immune cells called neutrophils coordinate an inflammatory response which can exacerbate the damage to the organ. Now researchers have shown that neutrophils also promote cardiac repair.
