Like many people, rats are happy to gorge themselves on tasty, high-fat treats. Bacon, sausage, chocolate and even cheesecake quickly became favorites of laboratory rats that recently were given access to these human indulgences--so much so that the animals came to depend on high quantities to feel good, like drug users who need to up their intake to get high.

Motherhood appears to protect against suicide, with increasing numbers of children associated with decreasing rates of death from suicide, found a new article.

Scientists have determined the structure of a previously unseen part of the insulin receptor, making possible new treatments for diabetes.

Using a novel animal model to study craniofacial pain, researchers have discovered that when tissues are inflamed, the nerve cells carrying pain information from the head to the brain produce in large quantities a protein involved in pain signaling.

Dolphins, whales and porpoises have extraordinarily small balance organs, and scientists have long wondered why. Now a study has contradicted a leading theory, which held that the animals moved their heads so vigorously that they had to have smaller, less responsive balance organs to avoid overwhelming their senses.

A new technique will deliver cancer treatments directly to certain tumors. One of the cancers this could have particular benefit in targeting is pancreatic cancer, which is currently very difficult to treat.

Using the latest in aberration-corrected electron microscopy, researchers have obtained the first images that distinguish individual light atoms such as boron, carbon, nitrogen and oxygen.

Tuna steak. Tuna tartare. Toro , as the Japanese call it, or the fatty underbelly of the bluefin tuna served as sushi --a delicacy that became more common with the advent of cheap refrigeration in the 1960s. These are just some of the ways that humans consume one of the few warm-blooded fish.  

Unfortunately that love for bluefin tuna has led to overfishing , despite the fish's ability to swim as fast as 80 kilometers per hour. The Atlantic population of the giant fish that grows to an average of more than 360 kilograms has fallen by 90 percent. And the estimated global population is less than half what it was in 1970.

Lightweight, sturdy and non-corrosive: fiber-reinforced thermoplastics are an ideal material for making boats and cars, and for aerospace engineering. But up to now, processing the raw materials was considered laborious and costly. Researchers have now demonstrated how lasers can make the manufacturing of structures out of fiber-reinforced thermoplastics efficient, clean, reliable and automatic.
