Mothers teach babies fear through smell

Babies can learn what to fear from the first days of life simply by smelling their distressed mothers, a new study has shown. This doesn’t only work after the pregnancy, but also during it and even before – if a mother experiences something specific which makes her fearful. It’s the first direct observation of this […]

Novel treatment changes mood immediately for the chronically depressed

Promising results are reported by physicians who incorporate magnetic stimulation in their treatments for depression. Typically, this kind of treatment takes a long time until changes in mood are seen or, in some cases, causes unwanted side effects.  McLean Hospital researchers report a new treatment that uses low field magnetic stimulation that immediately improves mood and […]

Regularly exercising reduces risk of dementia by 40%

We’ve all read and heard about how exercise can dramatically boost our quality of living, but how many people actually take action? Very few. Less than 20% of Americans over the age of 18 meet the official recommended guidelines. This is really alarming, because what most people don’t know is that mild exercising has fantastic returns, […]

Why people love it when the bass drops

Rave parties go crazy when the bass drops, no doubt about it, but what makes people click so well with low frequencies? Canadian scientists at the McMaster Institute for Music and the Mind investigated how our brains react to low-freq pitches and found our affinity has to do with how humans detect rhythm. Basically, the bass is […]

Mutant worm that doesn’t get drunk could help end alcoholism

An unlikely worm might help millions of people fighting alcohol addiction. No, you won’t find it in tequila, but in the labs of neuroscientists at University of Texas at Austin who have engineered  Caenorhabditis elegans - one of the most popular animal models in science – to become insensitive to alcohol intoxication. The findings, if replicated on […]

Wobbly Winners: The Link Between Motion Sickness and Mobile Gaming

It’s common sense why some ailments correlate with gaming. Repetitive motion and long periods of holding a controller or mobile device lend themselves to carpal tunnel syndrome, while excessive sitting can lead to everything from stiff muscles to heart strain. But now some games for mobile platforms are turning up a new medical concern for […]

Natural painkiller found in human spit is six times more powerful than morphine

A new painkiller chemical derived from human spit has proven to be up to six times more potent than morphine when tested on rats in a laboratory setting. While painkillers have been thoroughly researched for decades, the industry alone amounting to billions of dollars every year, it’s been rather difficult for scientists to find natural […]

Chemical switch found in Alzheimer’s and stroke victims’ brains kills neurons

Researchers at the Sanford-Burnham Medical Research Institute (Sanford-Burnham) have found a chemical switch that both regulates the generation of new neurons from neural stem cells and the survival of existing nerve cells in the brain. Postmortem examination of the brains of Alzheimer’s patients and stroke victims found the switch that shuts off the signals was […]

Suspended nanojuice allows real-time imaging of the gut

By virtue of its clogginess, the human gut, particularly the small intestine, is difficult to examine and diagnose for potential diseases or afflictions. Irritable bowel syndrome, coeliac disease and Crohn’s disease are just a few of the most common diseases that affect the small intestine and can lead to severe complications. In fact, some 35,000 […]

Magic mushrooms dissolve self and amplify brain’s dream areas

British researchers at Imperial College London and Cardiff University have provided more insights into the mechanics of consciousness-altering psychedelics. Their work suggests the brain is altered while on psilocybin – the active psychoactive ingredient found in magic mushrooms – expanding consciousness and activating regions of the brain that are typically channeled during dream state. The study […]
