The two species (Pseudotropheus emmiltos and Pseudotropheus fainzilberi ) are found in the north western part of Lake Malawi. Until now, the only known…
Even sharks — which have existed for more than half a billion years— have the recipe for fingers in their genetic cookbook — not to eat them, but to grow them.
“We were quite surprised by the unexpected quality control mechanism that ensures the quality of breast milk,” says Ronald M. Evans, Ph.D., professor in the…
It is widely known that birds learn to fly through practice, gradually refining their innate ability into a finely tuned skill. However, according to Dr Jim…
Dr Glenn Burley has been awarded one of only 8 coveted Advanced Research Fellowships in Chemistry worth £922,000, given annually by the Engineering and…
It can also reveal injurious and risky consumption, such as repeated weekend binges. The method is quicker, cheaper, and more accurate than present variants,…
Increased functional and cellular complexity can be explained, in large part, by how genes and the products of genes are regulated. A University of Toronto-led…
A new study in the Journal of Biogeography by Danilo Russo and colleagues suggests that this is certainly the case for horseshoe bats (Rhinolophidae). These…
In the case of Escherichia coli, the bacteria studied, this is as much as 1,000 times higher than previously believed. The study also suggests that many more…
The study, which highlights the role of mitochondrial genome variation in the pathogenesis of common diseases, is published online in Genome Research…
In the late Paleozoic Era, with atmospheric oxygen levels reaching record highs, some insects evolved into giants. When oxygen levels returned to lower levels,…

In some ways, certain tumors resemble bee colonies, says pathologist Tan Ince. Each cancer cell in the tumor plays a specific role, and just a fraction of the…
Visible only under a very high-resolution light microscope, the dynamic waves are made of a signaling protein that directs cell movement. This protein and a…
“We have found that cocaine’s effects on the cardiovascular system can be reversed by the use of a drug called dexmedetomidine, which is currently approved by…
