Wind turbines are a valuable source of renewable energy, but it can be hard to find a good place to put them. They need to be close to a populated area so that transporting the power they generate isn't too expensive--bu...

The process of extracting natural gas from the earth or transporting it through pipelines can release methane into the atmosphere. Methane, the primary component of natural gas, is a greenhouse gas with a warming potenti...

The bad, old days NO GOOD deed, cynics say, goes unpunished. That is certainly the view of longline fishermen in southern Alaska. The good deed in question is the end of commercial whaling, courtesy of a moratorium agree...

A connection between disrupted energy production and the development of late-onset Alzheimer's disease has been uncovered by researchers.

A research advance may stop the progression of hearing loss and lead to significant preservation of hearing in people with Usher syndrome type III, a form of hereditary hearing loss linked to defects in the sensory "hair...

Mussels grip onto rock using stretchy fibres with self-repairing molecular bonds. Mimicking the trick has inspired an extremely tough and elastic new material

For younger patients with severe damage to the rotator cuff muscles, a "reverse" shoulder replacement provides lasting improvement in shoulder function, according to a study.

Four in five adults are infected with herpes simplex virus, say researchers, but most don't show symptoms like cold sores because the virus infection is 'latent' -- sleeping -- within the nervous system. While many virus...

New research supports the idea that multiple sclerosis (MS), which has widely varying symptoms and progression in different patients, is nonetheless a single disease with common underlying mechanisms.

In older women with cataracts, cataract surgery appears to be associated with a lower risk for overall and cause-specific death, although whether this association is explained by the intervention of cataract surgery is u...

Malaria is a parasitic disease transmitted between humans through the bite of a mosquito. By identifying two proteases essential for the parasite's survival and dissemination as well as a molecule capable of inhibiting t...

Although bacteria have no sensory organs in the classical sense, they are still masters in perceiving their environment. A research group has now discovered that bacteria not only respond to chemical signals, but also po...

Manipulating mitochondrial networks inside cells -- either by dietary restriction or by genetic manipulation that mimics it -- may increase lifespan and promote health, according to new research.

Screening for tumor cells in the fallopian tubes of women at high-risk for ovarian cancer may help detect the cancer years before it develops further, suggests a new study. The work traces the origins of high-grade serou...

Congenital heart valve defects are the most common type of birth defects, the majority of which have no clear genetic cause, suggesting that epigenetic factors play an important role. Now, researchers have found that the...

A recent study indicates that pregnancy does not incur a greater risk of relapse for survivors of breast cancer.

Researchers have for the first time confirmed how neurons control muscle movement.

Using cryo-electron microscopy, researchers have analyzed the structure of trypanosomes parasites in details and revealed one of their potential weak points, which has remained undetected until now. This discovery opens ...

Researchers found mutations in a master-switch protein called Epithelial Splicing Regulatory Protein 1 in individuals with a type of congenital hearing loss. In general, what connects most of the unexplained hearing-loss...

New research has helped to reduce the over-prescription of unneeded antibiotics to children in rural China, according to research.

Assaults decrease by 3 percent the Monday after the switch to Daylight Saving Time in the spring. In the fall, the opposite takes place, with violence rising by about the same percentage.

Using an advanced form of optical microscopy, scientists have uncovered how oxygen levels -- even those in different brain hemispheres -- connect to share signals when the body rests. Their results have immediate impact ...
