Newly discovered mechanism enables precise gene regulation by combining DNA and RNA epigenetics
Our genes contain all the instructions our body needs to function, but their expression must be finely regulated to guarantee that each cell performs its role optimally. This is where DNA and RNA epigenetics come in: a series ...

Shocking cues: How cells harness electric fields to migrate during embryonic development
As an embryo grows, there is a continuous stream of communication between cells to form tissues and organs. Cells need to read numerous cues from their environment, and these may be chemical or mechanical in nature. However, ...

Isotopes in early South African hominin teeth show they ate little meat
A team of climate geochemists at the Max Planck Institute for Chemistry, University of the Witwatersrand and Princeton University has found evidence that early hominins living in South Africa ate a mostly vegetarian diet. ...
New fossil species sheds light on divergent life-history strategies in early land plants
The initial radiation of vascular land plants, evidenced by increases in both diversity and morphological disparity during the Silurian and Devonian periods, is considered plant terrestrialization, which can be seen as the ...

Climate change driving 'cost-of-living' squeeze in lizards
Desert lizards are facing a 'cost-of-living' squeeze as global temperatures continue to rise, a new study finds. For a lizard, the 'cost-of-living' is tightly linked to its body temperature, which dictates both how much food ...

Biologists shed light on the physiology and behavior of cormorants and anhingas
They are two of Florida's most iconic waterbirds, who look and behave similarly, but it turns out the anhinga and the double-crested cormorant are quite different, new research from the University of Miami indicates.

Mind's eye: How fish detect color and brightness with the brain's pineal gland
We see color because photoreceptor cones in our eyes detect light waves corresponding to red, green, and blue, while dimness or brightness is detected by photoreceptor rods. Many non-mammalian vertebrates like fish, however, ...
