Randomness forms complex social structures

(Phys.org)—The environment of group-living animals influences their social behaviour in a stronger way than was previously thought, says a new study from behavioural researchers at ETH and the University of Zurich. They ...

Culture of an amphibian killer

(Phys.org)—In the November issue of the journal Molecular Ecology, a U.S. and Brazilian research team reported evidence of novel and hybrid strains of a lethal fungus that has decimated amphibian populations worldwide. ...

Study sheds light on genetic 'clock' in embryonic cells

As they develop, vertebrate embryos form vertebrae in a sequential, time-controlled way. Scientists have determined previously that this process of body segmentation is controlled by a kind of "clock," regulated by the oscillating ...

First mouse, now human, lab-grown eye tissue

Producing retinal tissue from human embryonic stem cells is now possible thanks to a team of researchers led by Yoshiki Sasai of the RIKEN Center for Developmental Biology in Kobe, Japan.

Brain study: Singing mice show signs of learning

Guys who imitate Luciano Pavarotti or Justin Bieber to get the girls aren't alone. Male mice may do a similar trick, matching the pitch of other males' ultrasonic serenades. The mice also have certain brain features, somewhat ...

No evidence for 30-nm chromatin fibers in the mouse genome

Scientists in Canada and the United States have used three-dimensional imaging techniques to settle a long-standing debate about how DNA and structural proteins are packaged into chromatin fibres. The researchers, whose findings ...
