In a first large-scale systematic study, researchers found that most sibling proteins -- known as 'protein isoform' encoded by the same gene -- often play radically different roles within tissues and cells, however alike they may be structurally.

A ban on federal funding of research into gun violence initiated by Congress in 1997 must be overturned to improve understanding of gun use and how best to control it, argue experts.

The UK's new alcohol guidelines are unlikely to have a direct impact on drinking, but they do raise awareness of harm and so may alter social attitudes towards alcohol, suggests an expert in a new article.

Asthma has been associated with a prolonged time to pregnancy and a decreased birth rate in a new clinical observation study. The current study investigated 245 women with unexplained fertility problems aged between 23 and 45 years. They underwent asthma and allergy testing and questionnaires…

Researchers have identified 27 genes in brain stem cells that are prone to a type of DNA damage. The fragility of those genes could explain why they are often mutated or deleted in cancers and neuropsychiatric disorders such as schizophrenia. But their tendency to break could also benefit the brain…

A specific microRNA has strong links to a number of neuropsychiatric disorders, including autism spectrum disorder, scientists report. The microRNA, known miR-980, serves as a memory suppressor in multiple brain regions of Drosophila, the common fruit fly, a widely recognized substitute for human…

Personality characteristics -- especially conscientiousness -- have previously been shown to have a significant but moderate influence on academic achievement. However, a new study suggests that 'grit,' defined as perseverance and passion for long-term goals, adds little to the prediction of school…

Most of us can remember the Grey's Anatomy episode where Meredith's step-mom checks into the hospital for a case of hiccups that won't go away. The diagnosis wasn't pretty and it may have caused viewers to panic about their health every time they hiccupped.

An advanced system for treating manure on a commercial dairy farm did not remove estrogens and antibiotics. This new research underscores how far waste treatment systems have fallen behind the times, failing to remove chemicals used routinely in modern society.

People with sleep apnea show significant changes in the levels of two important brain chemicals, which could be a reason that many have symptoms that impact their day-to-day lives, new research concludes.

A type of study commonly used to pinpoint genetic variants associated with diseases can also be used to identify the lifestyle predictors that increase the risk of a disease -- something that is often overlooked in genetic studies.

New discoveries are bringing scientists closer to understanding how DNA repairs itself with a chemical modification which, when absent, can lead to tumor formation.

Researchers may have found a new way to diagnose Lyme disease, based on a distinctive gene "signature" they discovered in white blood cells of patients infected with the tick-borne bacteria.

One gene that was once thought only to be found in the brain is also expressed in breast cancer and helps promote the growth and spread of the disease, research shows. Additionally, the scientists showed how a version of the gene with edited RNA prevents metastasis.

Many patients with cancer find themselves in great financial distress, in part because the costs of cancer-fighting drugs are skyrocketing. Is it possible to create public policy that will rein in these prices and cut patients' out-of-pocket costs? Not without significant tradeoffs, that could…

A new study tested two generic lamotrigine (prescription antiepileptic) products and found no detectable difference in clinical effects among patients in the trial.

While causal relationship cannot be inferred, findings of a new study are "absolutely encouraging," says the lead author of a new report. The study shows for the first time that there is an association of verapamil use and lower fasting glucose levels in humans with diabetes

Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are two devastating adult-onset neurodegenerative disorders. No cure exists for these diseases. Ten percent of ALS patients suffer from a familial form of the disease, while FTD is caused in 40% of patients by a genetic defect.…

What makes some words easier to learn than others? Researchers found that ideophones — words that sound like what they mean — are easier to learn than regular words. This suggests that some of our associations between sound and meaning may be universal. Often, the sound of a word doesn't say much…
