Hydra became a subject of a recent study because of its unique ability to tear itself in order to gulp its prey. Hydra is a small freshwater creature which lies beneath water. It has no mouth or lips unlike majority of creatures.

Boston College researchers have uncovered the worldwide spread of an ancient group of retroviruses that affected ancestors of roughly 28 of 50 modern mammals nearly 15 to 30 million years back.

Retroviruses are widespread and consists human immunodeficiency viruses (HIV-1 and -2) and human T-cell leukemia viruses. The findings of the scientists on a particular group of these viruses known as ERV-Fc have shown that they affected a large number of hosts, like species as diverse as primates, carnivores, and rodents. The results will appear in journal eLife.

An enduring paleontology mystery could have been finally solved. It is the baffling case of the demise of a very successful group of dolphin-like marine reptiles known as ichthyosaurs that thrived in the oceans on the planet for over 150 million years.

Flu is a respiratory infection that develops primarily in the lungs and spreads from person to person following secretions of the nose and lungs, especially while sneezing. In medical terms, this viral infection is called influenza.

The common symptoms of influenza include higher fever, more malaise and severe body aches and the viruses are categorized in three types: A, B, and C. While A and B-type influenza are responsible for epidemics of respiratory illness that occur almost every winter, C category usually causes either a very mild respiratory illness or no symptoms at all. Types A and B cause epidemics and can have severe impact on public-health.

It has turned out that men who depend on other men for support, advice and companionship could be onto something. A latest study conducted by the University of California, Berkley, has found that when men are social with each other, they could be more resilient to stress.

At least the phenomenon is true in the case of rats. The researchers wanted to know how social relationships can possibly influence rodents' ability of dealing with stress.

The researchers roomed male rats together. They shared same cage, and were exposed to a mild stressor. They noticed that the animals were more social than they tended to be in an environment that wasn't stressful.
