New gene-scanning approach finds link to heart attack risk 'hiding in plain sight'

As scanning genomes for disease-related gene variations becomes more commonplace, scientists are pinpointing gene variations that change the way proteins function. Using this approach, a new study found a previously unknown gene variation that appears to make blood lipid levels healthier in humans and reduce risk of heart attacks.

Better sleep linked with higher omega-3 levels in new study

Omega-3 fatty acids are most commonly derived from fish oils, including tuna and salmon, and they have been linked to numerous health benefits.

Or do you pick it up, give it a quick wipe and eat it? Many of us would refer to the "5-second rule" to justify eating it. Now, new research suggests this urban myth may actually hold scientific fact.

New study suggests contagious yawning is not linked to empathy

Along with the whereabouts of Bigfoot and the answer to whether we are alone in the universe, the mechanism behind contagious yawning remains one of life's great mysteries. Though previous studies have suggested a link to empathy, new research suggests this is not the case, rendering it still largely unexplained.

HIV vaccine hope found in immune system of a unique patient

The Journal of Clinical Investigation has published a new study of a unique patient with an immune system that produces the types of neutralizing antibodies that are considered essential to an effective HIV vaccine response.The patient has a rare combination of HIV and systemic lupus erythematosus or SLE, a disease where the immune system attacks the body's own cells and tissue.

Brain links weakened by nicotine withdrawal may explain smokers' relapse

A new brain imaging study published in JAMA Psychiatry suggests that the high rate of relapse among smokers trying to quit may be due to an inability - brought on by nicotine withdrawal - to switch from the "default mode" brain network, to the "executive control" brain network.
