Over the past few years, the Department of Energy's SLAC National Accelerator Laboratory has developed a new tool to visualize physical and chemical processes with outstanding clarity: an ultra-high-speed "electron camer...

(University of Leeds) University of Leeds researchers have calculated the EROI for fossil fuels over a 16 year period and found that at the finished fuel stage, the ratios are much closer to those of renewable energy sou...

Scientists at DESY have achieved a new world record for an experimental type of miniature particle accelerator: For the first time, a terahertz powered accelerator more than doubled the energy of the injected electrons. ...

More than half of new drugs entering the German healthcare system have not been shown to add benefit, argue researchers.

A new study has found that the gene, mEAK-7, which they discovered last year, may play a key role in cancer metastasis. By comparing mEAK-7 expression levels in normal and cancer cells, they found that the gene was highl...

Using arthroscopy to stage a lesion in the chondral area of the knee is more accurate than magnetic resonance imaging, according to researchers.

Patients receiving a post-surgery prescription of ibuprofen with a rescue prescription of Percocet used less opioids than a group of similar patients who were prescribed just Percocet.

The use of platelet-rich plasma therapy can reduce the risk of a second meniscus failure after operation but does not seem to protect patients who have had surgery to repair an anterior cruciate ligament, according to ne...

Scientists have discovered a novel mechanism and role in the brain for hyaluronic acid -- a clear, gooey substance popularized by cosmetic and skin care products. Hyaluronic acid may be the key in how an immune signal mo...

What if the missing 'environmental' factor in some of our deadliest neurological diseases were really written in our genome? Researchers explain how viruses ended up in our DNA -- and what puts them in the frame in unsol...

The humble house mouse has dramatically shaped parasitic Toxoplasma gondii populations in West Africa and around the world, according to new research. As different strains affect their hosts differently, the research pro...

Mycetoma is a common neglected disease caused by either fungi or bacteria which organize themselves into grains -- areas of inflammation surrounded by a collagen capsule. Now, researchers have studied two immune molecule...

A new computational model successfully predicts how daily pain sensitivity rhythms affect pain processing, both in healthy adults and in people with neuropathic pain.

First national study shows cutting residents' training hours has not resulted in lower performance for new doctors. Resident training was capped at 80 hours per week in 2003, down from 100+ hours, a controversial move th...

New research raises questions as to whether too many infants are getting tongue-tie and lip tether surgery (also called frenulectomy) to help improve breastfeeding, despite limited medical evidence supporting the procedu...

As a cucumber plant grows, it sprouts tightly coiled tendrils that seek out supports in order to pull the plant upward. This ensures the plant receives as much sunlight exposure as possible. Now, researchers have found a...

A team of scientists has compiled environmental and epidemiological data from around the world to develop a map that shows the riskiest areas for hepatitis E outbreaks. Their work opens the way to new avenues of research...

To date, most studies that have attempted to understand connections between neurocognitive function and sub-concussive head impacts have been retrospective -- and inconclusive.

A simple finger-prick blood test could help prevent unnecessary prescribing of antibiotics for people with the lung condition chronic obstructive pulmonary disease (COPD), according to a new study.

A key cause for the pelvic pain experienced by women with endometriosis has been uncovered, potentially opening new opportunities for pain relief for the condition.

Two proteins that act as a 'clutch' in cells to put them in gear and drive our immune response have been identified for the first time.

Something frightening or unpleasant does not go unnoticed. In our brain, the so-called limbic circuit of cells and connections immediately becomes active. First and foremost, such experiences activate the amygdala. In or...
