Several genes with strong associations to schizophrenia have evolved rapidly due to selection during human evolution, according to new research in the Proceedings of the Royal Society B.

 | Ancient DNA harvested from pigs has allowed scientists, for the first time, to accurately determine the arrival of early farmers into Europe 11,000 years ago during the latter part of the Stone Age. ...> Full Article |
 | Archaeological proof of the Biblical description of Israel really as "the land of milk and honey" (or at least the latter) has been uncovered by researchers from the Hebrew University of Jerusalem Institute of Archaeology. ...> Full Article |
Plant biologists at the Max Planck Institute of Developmental Biology and the University of North Carolina at Chapel Hill have discovered that an autoimmune response, triggered by a small number of genes, can be a barrier to producing a viable offspring.

 | The African origin of early modern humans 200,000--150,000 years ago is now well documented, with archaeological data suggesting that a major migration from tropical east Africa to the Levant took place between 130,000 and 100,000 years ago via the presently hyper-arid Saharan-Arabian desert. ...> Full Article |
 | It appears that chemical warfare has been around a lot longer than poison arrows, mustard gas or nerve weapons -- about 100 million years, give or take a little. ...> Full Article |
 | A major achievement has been reached in plant biology: the first detailed analysis of the grapevine genome has just been published. The joint effort carried out by scientists from Genoscope and INRA in France and from several Universities and the Istituto di Genomica Applicata (IGA) in Italy has produced a high-quality draft of the genome sequence of Vitis vinifera, the first for a fruit crop, cultivated for both fruit and beverage. ...> Full Article |
 | A team of scientists led by young Croatian evolutionary geneticist Tomislav Domazet-Lošo from Ruder Boškovic Institute (RBI) in Zagreb, Croatia, developed a novel methodological approach in evolutionary studies. Using the method they named 'genomic phylostratigraphy', its authors shed new and unexpected light on some of the long standing macroevolutionary issues, which have been puzzling evolutionary biologists since Darwin. ...> Full Article |
 | Witnesses say it looks like a cross between a dinosaur and a vampire. Others say it's a hopping wolf with red eyes and a trail of foul smell, while some claim it resembles a small panther with a forked tongue. ...> Full Article |
 | Ancient cities arose not by decree from a centralized political power, as was previously widely believed, but as the outgrowth of decisions made by smaller groups or individuals, according to a new study from researchers at Harvard University, the University of Cambridge, and the University of Edinburgh. ...> Full Article |
 | In the September issue of The American Naturalist, Juan Carranza (Biology and Ethology Unit, University of Extremadura, Spain) and Javier Pérez-Barbería (Macaulay Institute, United Kingdom) offer a new explanation for why males of ungulate species subjected to intense competition are born with lower survival expectancies than females. ...> Full Article |
 | With the eye of an electrical engineer, Nels Peterson is hoping to bring a new, high-tech tool to the field excavation of dinosaurs, a labor of picks, shovels and brushes that has changed little over the past 100 years. ...> Full Article |
More than three million years ago, early hominins evolved the ability to walk upright and in doing so started us along the evolutionary path that eventually gave rise to Homo sapiens.

 | Antarctica is home to the largest body of ice on Earth. Prior to approximately 10 years ago, no one thought that life could exist beneath the Antarctic ice sheets, which can be more than two miles thick in places, because conditions were believed to be too extreme. However, Brent Christner, assistant professor of biological sciences at LSU, has spent a great deal of time in one of the world's most hostile environments conducting research that proves otherwise. ...> Full Article |
 | The mating ritual of the honey bee is a mysterious affair, occurring at dizzying heights in zones identifiable only to a queen and the horde of drones that court her. Now a research team led by the University of Illinois has identified an odorant receptor that allows male drones to find a queen in flight. The receptor, on the male antennae, can detect an available queen up to 60 meters away. ...> Full Article |
 | Twenty-two mummies in central Mexico-including one believed to be the world's youngest embalmed mummified fetus-have revealed clues to their identities, thanks to research conducted by a team of scientists this summer. ...> Full Article |
 | In a groundbreaking study, two Harvard scientists have for the first time extracted human DNA from ancient artifacts. The work potentially opens up a new universe of sources for ancient genetic material, which is used to map human migrations in prehistoric times. ...> Full Article |

 | Some leading scientists who have studied warfare through the ages have long suggested that humans — the males of the species, at least — have little choice when it comes to slaughtering one another in great numbers. Such warlike behavior, the scholars contend, is hardwired into the human brain. ...> Full Article |
 | Biologists at Harvard University have identified the ancient fossilized remains of a pollen-bearing bee as the first hint of orchids in the fossil record, a find they say suggests orchids are old enough to have coexisted with dinosaurs. ...> Full Article |

 | Female beetles mate to quench their thirst according to new research by a scientist from the University of Exeter's School of Biosciences. The males of some insect species, including certain types of beetles, moths and crickets, produce unusually large ejaculates, which in some cases can account for around 10% of their body weight. The study shows that dehydrated females can accept sexual invitations simply to get hold of the water in the seminal fluid. ...> Full Article |

 | Cooperation is widespread in the natural world but so too are cheats -- mutants that do not contribute to the collective good but simply reap the benefits of others' cooperative efforts. In evolutionary terms, cheats should indeed prosper, so how cooperation persists despite the threat of cheat takeover is a fundamental question. Recently, biologists at the Universities of Edinburgh and Oxford have found that in bacteria, cheats actually orchestrate their own downfall. ...> Full Article |
