New evidence uncovered by oceanographers challenges one of the most long-standing theories about how species evolve in the oceans. Researchers propose that it was the climate, and its role in determining the availability of favorable oceanic habitat, that restricted the distribution of the species they studied rather than the presence of physical ocean barriers. In [...]

Psychologists reveal that religion facilitates the exercise of self-control and attainment of long-term goals. A psychology professor has found a strong correlation between religion and self-control, or self-regulation. He explains that religious people may have at their disposal a set of unique resources that makes them better suited to adhering to long term goals.
A research group lead by scientists at the University of Warwick has discovered the trigger that pulls together X chromosomes in female cells at a crucial stage of embryo development. This is an important mechanism as the binding together of too many of too few of a particular chromosome can cause a number of medical [...]
New calculations predict that germanium hydride will be superconducting at relatively high temperatures, but will be easier to process than the high-temperature superconductors known up to now.

An extract from grape seeds forces laboratory leukemia cells to commit cell suicide. Researchers found that within 24 hours, 76 percent of leukemia cells had died after being exposed to the extract.
The critically endangered Tristan albatross has suffered its worst breeding season ever. The number of chicks making it through to fledging has decreased rapidly, and it is now five times lower than it should be because introduced predatory mice are eating the chicks alive on Gough island — the bird’s only home and a South [...]

Like high-profile politicians, pathogenic bacteria dispatch advance teams to make way for their arrival. But these bacterial agents don’t just secure a safe passage, as a Secret Service detail might do. Rather they are teams of molecules that bacteria inject into cells they want to colonize, sent to hijack their hosts’ biochemistry to serve their [...]

New interpretations of fossils have revealed an ancient missing link between today’s spiders and their long-extinct ancestors. The research by scientists at the University of Kansas and Virginia’s Hampden-Sydney College may help explain how spiders came to weave webs.
