Gene expression altered by direction of forces acting on cell

Tissues and cells in the human body are subjected to a constant push and pull—strained by other cells, blood pressure and fluid flow, to name a few. The type and direction of the force on a cell alters gene expression by ...

Mosquitos lost an essential gene with no ill effects

University of Maryland entomologists discovered that a gene critical for survival in other insects is missing in mosquitos—the gene responsible for properly arranging the insects' segmented bodies. The researchers also ...

Study traces the evolution of gill covers

The emergence of jaws in primitive fish allowed vertebrates to become top predators. What is less appreciated is another evolutionary innovation that may have been just as important for the success of early vertebrates: the ...

Primate brain size does not predict their intelligence

Chimpanzees, gorillas and orangutans are our closest relatives, and like us they have relatively large brains and they are very intelligent. But do animals with larger brains really perform better in cognitive tests? A research ...

The surprising organisation of avian brains

Birds and mammals have the largest brains in relation to their body. Apart from that, however, they have little in common, according to scientific opinion since the 19th century: mammalian brains have a neocortex, i.e. a ...

Scientists discover why tarantulas come in vivid blues and greens

Why are some tarantulas so vividly colored? Scientists have puzzled over why these large, hairy spiders, active primarily during the evening and at night-time, would sport such vibrant blue and green colouration—especially ...

Penicillium camemberti: a history of domestication on cheese

The white, fluffy layer that covers Camembert is made of a mold resulting from human selection, similar to the way dogs were domesticated from wolves. A collaboration involving French scientists from the CNRS has shown, through ...

Genome duplications as evolutionary adaptation strategy

Genome duplications play a major role in the development of forms and structures of plant organisms and their changes across long periods of evolution. Heidelberg University biologists under the direction of Prof. Dr. Marcus ...

Placing barthelonids in evolutionary context

New species of microbial life are continually being identified, but localizing them on a phylogenetic tree is a challenge. Now, researchers at the University of Tsukuba have pinpointed barthelonids, a genus of free-living ...

Biodiversity hypothesis called into question

Biologists have long considered the origins and continued coexistence of the immense diversity of species found in our environment. How can we explain the fact that no single species predominates? A generally accepted hypothesis ...
