Researchers say a 3.4 million-year-old fossilized foot found in Ethiopia did not belong to a member of Australopithecus afarensis, the hominin species of our early upright-walking ancestor “Lucy”, but to a tree-climbing hominin cousin with whom she…
If you go far enough back along the branch of the evolutionary tree of life that humans sit on, you get to the part near the trunk where verterbrates (creatures with spines) split from invertebrates (creatures without spines). Current theories sugges…

A new study, published in the March 9 issue of Science , reveals that by engineering cells to express a modified RNA called “Spinach”, researchers from the Weill Cornell Medical College have advanced in reproducing small-molecule metabolites, i.e. inte…
Although our bodies seem to be bilaterally symmetrical at a glance, the way in which our organs are stereotypically located shows they are internally typically asymmetrical, for instance, whilst the heart is located on the left hand side, the liver is …
The science journal Proceedings of the National Academy of Sciences , has reported that scientists from the University of Leicester and Cardiff University have achieved a breakthrough in understanding how a ‘biochemical switch’, known as P2X1, which is…
Two studies published online, ahead of the April issue of the American Journal of Obstetrics & Gynecology (AJOG), show that the risk of a fetus having chromosomal abnormalities that cause Down syndrome, and a genetic disorder known as Edwards syndrome,…
Writing in the February 17, 2012 issue of the journal Cell, researchers at the Ludwig Institute for Cancer Research, the University of California, San Diego School of Medicine and the Toronto Western Research Institute peel away some of the enduring my…
Scientists at the University of California, San Diego have developed a new method for making scaffolds for culturing tissue in three-dimensional arrangements that mimic those in the body. This advance, published online in the journal Advanced Materials…
All living organisms are made up of cells, behind these intricate life forms lie complex cellular processes that allow our bodies to function. Researchers working on protein secretion – a fundamental process in biology – have revealed how protein chann…
