When all else is equal, human children prefer to work together in solving a problem rather than on their own. Chimpanzees, on the other hand, show no such preference. That's according to a study of 3-year-old German kindergarteners and semi-free-ranging chimpanzees reported online on October 13 in Current Biology, a Cell Press publication.

Researchers reporting online in the journal Cell, a Cell Press publication, on October 13th have found another good reason to eat your green vegetables, although it may or may not win any arguments with kids at the dinner table.

It turns out that green vegetables -- from bok choy to broccoli -- are the source of a chemical signal that is important to a fully functioning immune system. They do this by ensuring that immune cells in the gut and the skin known as intra-epithelial lymphocytes (IELs) function properly.

BOSTON -- In findings with major implications for the genetics of cancer and human health, researchers at Beth Israel Deaconess Medical Center (BIDMC) and two other science teams in New York City and Rome have uncovered evidence of powerful new genetic networks and showed how it may work to drive cancer and normal development.

A breakthrough in the study of chlamydia genetics could open the way to new treatments and the development of a vaccine for this sexually transmitted disease.

For decades research progress has been hampered because scientists have been prevented from fully understanding these bacteria as they have been unable to manipulate the genome of Chlamydia trachomatis.

Now researchers in Southampton have made a significant breakthrough in accessing the chlamydial genome and believe it could pave the way for more effective treatment of the disease.

At least 20 million people survive heart attacks and strokes every year, according to World Health Organisation estimates, but many have poor life expectancy and require continual costly clinical care. The use of patient's own stem cells may repair heart attacks, although their benefit may be limited due to scarce availability and ageing. The researchers have found heart muscle-like cells grown using stem cells from human umbilical cord blood could help repair heart muscle cells damaged by a heart attack.

New research from the Universities of Portsmouth and Leicester has identified a small fossil fragment at the Natural History Museum, London as being part of a giant pterosaur – setting a new upper limit for the size of winged and toothed animals.

Dr David Martill from the University of Portsmouth and Dr David Unwin from the University of Leicester examined the fossil - which consisted of the tip of a pterosaur snout that had been in the Museum collections since 1884.

The highly social cichlid fish Neolamprologus pulcher, endemic to Lake Tanganyika in Africa, live in social groups consisting of a dominant breeding pair and between 1 and 15 subordinates of both sexes that perform brood care, territory defence and maintenance. Subordinates are often distantly related or unrelated to the dominants.

The species of legume known as 'Tallante's chickpea', which has not been seen for nearly a century, has finally been studied in detail. The species is thought to be in critical danger of extinction given that the only known population in the whole world is in Tallante, Murcia (Spain).

A study reveals its characteristics and the reasons as to why the Astragalus nitidiflorus legume, or Tallante's chickpea, remains critically endangered. Researchers wants to restore this floral plant which is unique to the region of Murcia, Spain and, up until recently, was thought to be extinct.

No one is in a better position to monitor environmental conditions in remote areas of the natural world than the people living there. But many scientists believe the cultural and educational gulf between trained scientists and indigenous cultures is simply too great to bridge -- that native peoples cannot be relied on to collect reliable data.

Thanks to Hollywood, piranhas have a bad reputation and it would be a brave scientist that chose to plunge their hand into a tank of them. But that didn't deter Sandie Millot, Pierre Vandewalle and Eric Parmentier from the University of Liège, Belgium. 'You just have to pick them up and they make sounds,' says Parmentier. However, it wasn't clear when and why piranhas produce sounds naturally.

New research to be published Oct. 13 confirms The Beatles' lyrical hypothesis and finds that "the kind of thing that money just can't buy" is a happy and stable marriage.

Scholars at Brigham Young University studied 1,734 married couples across the country. Each couple completed a relationship evaluation, part of which asked how much they value "having money and lots of things."

Particular types of mouth bacteria, some of which are found in gum disease, are associated with the development of pancreatic cancer, indicates a small study published online in the journal Gut.

The finding opens up the possibility of curbing the progress of one of the most difficult cancers to treat, by altering the balance of bacteria, say the authors.Pancreatic cancer usually spreads very quickly, and only around one in 20 patients is still alive five years after diagnosis.
