The Thalamus not only relays visual signals from the eye to the visual cortex as previously thought, but also conveys additional, contextual information. Integrating these different signals is essential to understand and interpret what we see in the world around us. Researchers investigate how the…

Researchers have, for the first time, described the pivotal changes responsible for controlling the formation of the part of the brain that allows us to learn and execute complex movements. These changes involve modifications to chromatin, which is DNA packaged with protein.

14- and 15-year-olds are at a higher risk of becoming dependent on prescription drugs within a 12-month period after using them extra-medically, or beyond the prescribed amount, new research has determined.

Palbociclib, a new oral drug whose efficacy in combating breast cancer has been demonstrated alone and in combination with endocrine therapy, also has potential to combat other types of cancer, according to a literature review and additional original research.

Following the introduction of plain packaging on tobacco products in 2012, Australian Aboriginal and Torres Strait Islander people were 12 percent less likely to think certain tobacco brands were less harmful than others, a new study found.

''Will you exercise this year?' That simple question can be a game-changing technique for people who want to influence their own or others' behavior, according to a recent study spanning 40 years of research.

The pathogenic bacterium Bacillus cereus causes vomiting and diarrhea as well as systemic and local infections. A team of researchers has reported for the first time that B. cereus, following contact with certain antibiotics, can switch into a special slowed-down mode. The bacteria then form small…

In one of the most tightly controlled trials ever conducted of drugs used to treat sexually transmitted infections, researchers have confirmed that azithromycin remains effective in the treatment of urogenital chlamydia.

Lives of soldiers and others injured in remote locations could be saved with a cell-free protein synthesis system, say scientists. The device uses microfabricated bioreactors to facilitate the on-demand production of therapeutic proteins for medicines and biopharmaceuticals. Making these miniature…

The use of ultrasound in detecting breast cancer has been shown to be comparable in its sensitivity to that of mammography and should be considered when testing for the disease according to a new study.

An Undiagnosed Diseases Program provides an ending for one family's 24 year search for answers to their children's health issues.

One researcher is concerned that there's more to the problem of antibiotic-resistant bacteria than the misuse of common medications. A senior research ecologist, this scientist believes environmental contaminants may be partly to blame for the rise in bacterial resistance, and he tested this…

Two genetic variants previously linked to Alzheimer's disease have been more specifically tied to brain atrophy that is characteristic of the disease. Alzheimer's disease is a progressive illness that is the leading cause of dementia and the sixth leading cause of death in the United States. There…

Researchers have discovered the first-ever evidence-based description of the neuronal protein clumps thought to be important in Amyotrophic Lateral Sclerosis (ALS), also known as Lou Gehrig's disease, a fatal neurodegenerative condition. This research development could be a crucial step toward…

Fifteen years ago, scientists had determined the entire sequence of the genetic letters making up our DNA. But this was only a step in a long journey: in addition to the letters, information is also encoded in the packing of DNA. A team of researchers has now generated comprehensive 3-D maps of the…

A new approach has been developed that allows researchers to broadly survey learning-related changes in synapse properties. The researchers used machine-learning algorithms to analyze thousands of images from the cerebral cortex. This allowed them to identify synapses from an entire cortical…

Could hypnosis help to reduce the psychological trauma associated with 'awake craniotomy' for brain cancers? A new 'hypnosedation' technique offers a new alternative for patients undergoing awake surgery for gliomas, suggests a study.

A dozen inherited traits related to sleep, wake, and activity cycles that are associated with severe bipolar disorder have been identified by an international team of researchers.

The presence of myopia, or nearsightedness, significantly affects the muscles used in focusing the lens of the eye -- a finding with important implications for the development of 'accommodating' implanted intraocular lenses (IOLs) that can adjust to different visual distances, reports a new study.

An opioid prescribing guideline had an immediate and sustained impact on opioid prescribing rates for minor conditions and chronic noncancer pain in an acute care setting, emergency medicine physicians have found.

A proof-of-concept, phase 2 trial by an international research team has found promising results for a myostatin antibody in treating the decline in muscle mass and power associated with aging.

Eating too much is typically considered one of the prime culprits of obesity. Now a new study has looked specifically at overconsumption of 'healthy' foods which consumers often perceive as less filling.

It may be your liver (and not your better judgement) that keeps you away from excess sweets this holiday season. Two independent research groups have found the first evidence of a liver-derived hormone that specifically regulates intake of sugars and alcohol in mice. One of the studies also found…

While hospitals have made strides in reducing the time it takes to treat heart attack patients once they arrive at the hospital, patient delays recognizing symptoms and seeking treatment are associated with increased damage to the heart, according to a study.

Heart attack patients who had previously undergone coronary artery bypass graft surgery were less likely than other heart attack patients, including those with prior angioplasty, to be treated within the 90-minute recommended 'door-to-balloon time,' according to a study.
