Evolutionary history of three-finger snake toxins decoded

Snakebites cause around 100,000 deaths worldwide every year. Researchers at the Technical University of Munich (TUM) have investigated how the toxin emerged between 50 and 120 million years ago through the modification of ...

Hitting reset to start a new embryo

New work by scientists in the U.S. and China shows how a fertilized egg cell, or zygote, hits "reset" so that the newly formed embryo can develop according to its own genetic program. The study was published July 17 in Nature.

Discovery of new gene unveils sex determination in green algae

An international team of researchers led by Dr. James Umen at the Donald Danforth Plant Science Center has made a groundbreaking discovery in the world of developmental biology. In their latest study on volvocine green algae, ...

Scientists show how some of Earth's earliest animals evolved

Lacking bones, brains, and even a complete gut, the body plans of simple animals like sea anemones appear to have little in common with humans and their vertebrate kin. Nevertheless, new research from Investigator Matt Gibson, ...

New imaging technique can capture entire plant tissues in 3D

The cellular life inside a plant is as vibrant as the blossom. In each plant tissue—from root tip to leaf tip—there are hundreds of cell types that relay information about functional needs and environmental changes. Now, ...

Japanese researchers successfully induce primate oocytes in the lab

The many types of cells in the human body are produced through the process of differentiation, in which stem cells are converted to more specialized types. Currently, it is challenging for researchers to control the differentiation ...
