MIT researchers have found that one key role of the neuromodulator noradrenaline, produced by the locus coeruleus, is to help the brain learn from surprising outcomes.

While botanical gardens have evolved from their medicinal roots in 16th-century Italy, their plants can still bring peace and joy to our busy lives, says Beronda L. Montgomery

Researchers have applied a novel stem cell model to map disease risk variants in human neurons, which could help provide insights into the biological mechanisms that underlie neuropsychiatric disorders such as autism and...

Researchers have conducted a 10-week study to evaluate how text messaging a link to patients when their doctor is ready provides a way to connect patients and doctors without relying on the virtual waiting room.

A remarkable discovery and collaborative effort have revealed a new type of triterpenes, a group of organic compounds which are an important source of many medicines. Until now, all triterpenes were believed to be derive...

Individuals with HIV who began taking antiretroviral therapy (ART) in the early stages of infection achieved a lengthy period of HIV suppression without ART after receiving two broadly neutralizing anti-HIV antibodies (b...

Turns out you're not the only one who needs a good night's rest to function well the next day. Researchers found that mosquitoes whose slumber is disrupted are more interested in catching up on their sleep than looking f...

The highly dynamic, new "expanding hole" optical illusion can be perceived by 86% of people. The illusion is so good at deceiving the brain, it causes pupillary dilation as though we are walking into a darkened room.

A study suggests that substances touted to improve athletic performance can activate a receptor that accelerates the progression of pre-cancerous lesions to pancreatic cancer in mice.

The study reports a novel neuron type in the hippocampus, defines its functional role in the brain, discloses its connectivity with other nerve cells and brain areas and progresses the understanding of brain circuits und...

While there is some evidence that consuming omega-3 fatty acids in food or dietary supplements may reduce the risk of high blood pressure, the optimal amount to consume for this benefit is unclear. A review of dozens of ...

Chemists have created light-activated molecular machines and shown they can drill holes through the membranes of gram-negative and gram-positive bacteria, killing them in as little as two minutes. Their study offers a po...

Researchers analyzed the blood of Hikikomori patients and found key biomarkers for the condition included higher ornithine and long-chain acylcarnitine levels and lower levels of bilirubin and arginine. Further analysis ...

Sex-specific circuits in muscles signal to other tissues and organs, processing muscle impact differently in males and females.

The 'use-by' and 'best-by' dates printed on milk cartons and gallon jugs may soon become a thing of the past, giving way to more accurate and informative QR codes. A new study finds that consumers will use the QR codes -...

That has implications for paternal care

Scientists have utilized an objective and simple nutritional indicator called the Nutrition Risk Index (NRI) to unveil a long-suspected yet unverified relationship between sarcopenia and malnutrition in end-stage kidney ...

Researchers demonstrate that under low fluid shear force conditions that simulate those found in microgravity culture during spaceflight, the foodborne pathogen Salmonella infects 3-D models of human intestinal tissue at...

Some offspring of the spotted snow skink, a lizard found in Tasmania, are born anatomically male but are genetically female

Study reveals an association between signal detection theory, brain activation patterns, and subjective state fatigue. In those with multiple sclerosis, greater effects of fatigue were seen.

Researchers have discovered that 4,500-year-old seagrass meadows in Shark Bay, Western Australia, are actually the world's largest clone.

Researchers have developed drug-carrying nanoparticles that cross the blood-brain barrier, allowing for more effective delivery to the brain than conventional medications. The nanoparticles can get into tumors and kill g...
