The search behaviors of nearly 500,000 people from 50 countries has shed new light on how mood, gender, education, culture and where we live influences how we sate our curiosity and seek knowledge. So we ask: Are you a hunter, busybody or a dancer?

New research uncovering the DNA-damaging mechanism by which a mutated gene causes a rare, fatal disease may have repercussions for the treatment of many other diseases linked to aging, including heart disease, autoimmune disorders, and cancer.

Fish oil supplements containing omega-3 have long been touted as good for heart health. A new study has found they also reduce aggression. Researchers say the safe, common supplements should be used everywhere from the playground to the prison system.

Could ADHD have evolved in human populations to enhance a tribe's chances of successful foraging? A new study put this novel hypothesis to the test, recruiting several hundred people to play a specially made game measuring their foraging skills.

Almost 25 years since scientists first identified a difference in anesthetic sensitivity in males and females, a new study reveals how sex hormones make men more responsive to going and staying under. Yet dosage is still decided on by a patient's size.

A study has found that treatment with a ‘chemical chaperone’ reduced the accumulation of protein plaques and restored cognitive functioning in mouse models of Alzheimer’s, which could lead to novel treatments to help treat the debilitating disease.

For the first time, scientists have identified how going to bed stressed fires up certain brain cells at the wrong time in the sleep cycle to significantly interrupt it – and that suppressing this activity can ensure 'business as usual' slumber.

A study has uncovered how the commonly used local anesthetic drug lidocaine exerts an anti-cancer effect in head and neck cancers. Given its low cost and ready availability, the drug could easily be incorporated into treatment.

A new computer-trained scent model has done better than humans at identifying odors. In analyzing 500,000 potential odor molecules that had never before been synthesized, it also handily did work that would take 70 person-years to complete.

While completing an important task with other distraction such as TV can seem like it’s a battle of willpower, scientists have discovered how it's not you but your brain that keeps you on the right track. Or at least it tries to.

Memory is commonly affected following a traumatic brain injury. A new study has found that AI-guided electrical brain stimulation in people with moderate-to-severe traumatic brain injury may successfully treat their memory loss.

It's cheap, easy to transport, effective and non-invasive. Scientists have had their eye on genetically modified lettuce for insulin delivery for a while now (we're as surprised as you are), but it's one step closer after this promising animal trial.
