A research review has found that eating at least two handfuls of nuts a day may improve sperm quality – and, therefore, fertility – in young, healthy males. This simple strategy had positive effects without requiring any other changes to diet.

A clinical trial of a non-benzodiazepine drug, a version of a naturally occurring neurosteroid, has shown that it’s as effective as Xanax at reducing anxiety. Critical to the trial’s success was technology that converted the neurosteroid into oral form.

A new study has found that, in people over 60, a reduction in deep sleep by as little as 1% per year equated to a 27% increased risk of dementia. The findings suggest that enhancing or maintaining deep sleep may be a way of keeping the disease at bay.

With more than 1,000 bacterial species, the gut microbiome is an untapped resource of disease-fighting power. Now, scientists have found a way to rank crucial members of this 'microscopic multicultural community', which has massive medical potential.

A study has found that methotrexate, a widely available and affordable drug that’s usually prescribed as a first-line treatment for rheumatoid arthritis, is effective at reducing the pain and stiffness suffered by people with hand osteoarthritis.

A study has found that nighttime exposure to light increases the risk of mental illness, while daytime light exposure reduces it. The findings offer a simple and effective, non-pharmacological means of improving mental health.

Finally, science has given us permission to play with our food. Taking a unique recipe featuring a modified electronic plate and plenty of imagination, researchers have dished up a fun way of enhancing a food experience for both a chef and the diner.

Researchers have found a way to determine whether someone has suffered a concussion by measuring the blood levels of three biomarkers within six hours of the injury. The blood test could be used alongside existing tests for a more accurate diagnosis.

While research shows that taking a daily dose of aspirin could have some pros and cons, a new study adds a tick to the pro column. It was found that low-dose supplementation with the drug reduced type 2 diabetes development in adults over 65 by 15%.

Researchers have developed the world’s first oral drug to target a form of cholesterol that has previously been untreatable and is largely caused by genetics, making it difficult to control by way of exercise, diet or other lifestyle factors.

In a study of studies, researchers concluded that eyeglasses that block blue light might not deliver on claims made by advertisers or optometrist offices. They caution consumers to think twice about shelling out the extra cash for the specs.
