Researchers have discovered the probable cause of  several infectious agents at the same time. Paramyxoviruses originate from bats and from there the pathogens have spread to humans and other mammals. In total, the new study tested 9,278 animals for viruses, among them 86 species of bats and 33 rodent species, leading to the discovery of an enormous number of new virus species. This could make eradicating many dangerous diseases significantly more difficult than had been thought. For bats provide a reservoir from which viruses could come back after vaccination campaigns. 

Both testosterone and cortisol levels increased for Spaniards who watched as Spain beat Holland during the 2010 World Cup. 

In this study, they analyzed the psychobiological response of men and women watching sports - when the competition’s outcome, victory or defeat, is basically out of their control. Fifty supporters of the Spanish team watched the final in a public space or at home, with their families or friends. The researchers asked for their expectations and feelings before the match, and they checked their testosterone and cortisol levels before, during and after the match.

Researchers have documented the first fossil-based evidence supporting an evolutionary theory of aging, which predicts that species evolving in low mortality and resource-limited ecosystems tend to be more long-lived.

But that is not an endorsement of banning guns and caloric restriction. It's a little more complicated than that.

Climate change is in its fifth decade of being the big concern. In the 1960s and 70s, it was a cooling worry but now there is a warming one.  A constant in mammal's surviving numerous climate upheavals throughout earth history has been diversity - the relative range and distribution of mammalian families remained strikingly consistent throughout major climate changes over the past 56 million years.

During the Middle Palaeolithic, between 127,000 and 40,000 years ago, humans that lived along the banks of the river Manzanares (now Madrid, Spain) ate pachyderm meat and bone marrow, according to a study that found percussion and cut marks on elephant remains in the site of Preresa.

So if you want to try a fad paleolithic diet, get a cheap spear and see how you do bringing one of those babies down first.

Is it a shrub?  No one really knows. A fossilized specimen, a roughly elliptical shape with multiple lobes, totaling almost seven feet in length, was unveiled today at the North-Central Section 46th Annual Meeting of the Geological Society of America, in Dayton, Ohio.

Around 450 million years ago, shallow seas covered the Cincinnati region and harbored one very large and now very mysterious organism. Despite its size, no one has ever found a fossil of this "monster" until its discovery by an citizen paleontologist, Ron Fine of Dayton, last year.
