As opposed to bird song or the human voice, echolocation calls are primarily used for spatial orientation and search for food and not for communication. Bat…
By building powerful phylogenetic trees, scientists are able to quickly identify similarities and differences between the make-up of many different organisms,…
The sepals of the plant Arabidopsis thaliana—commonly known as the mouse-eared cress—are characterized by an outer layer of cells that vary widely in their…
Getting from point A to B may sound simple, but not so in the formation of fat cells. In a finding with potential drug-development implications, Mitchell A….
“It seems like something they don't understand,” said Julie Desjardins, a post-doctoral researcher in biology and lead author of a paper to be published in…
“Adult giant sharks, at 60-70 feet in length, faced few predators, but young sharks faced predation from larger sharks,” said Catalina Pimiento, visiting…
Adherens junctions, the structures that allow cohesion between cells in a tissue, appear to be modulated by endothelial cell-to-cell tugging forces. Both the…
AFM is one of major scientific tools responsible for the emergence of modern nanotechnology. The unprecedented sensitivity of AFM allowed the Clarkson team to…
Transcription factor (TF) proteins act as switches that turn genes on and off, and the timing and localization of their activity ensures that genes are…
A precise understanding of cellular growth and movement is the key to developing new treatments for cancer and other disorders caused by dysfunctional cell…
The findings reveal an essential step in the biology of the most common and severe malaria parasite, Plasmodium falciparum, and offer a new drug target for…
“We found that out of about 40,000 mouse genes, only 138 are commonly found in both male and female fat cells,” said Dr. Deborah Clegg, assistant professor of…
The ability of yeast cells to convert sugar to alcohol, the key process in the production of beer and wine, can be attributed to a remarkable evolutionary…
Japanese research group led by Prof. Makoto Tominaga and Dr. Takaaki Sokabe (National Institute for Physiological Sciences: NIPS) found that TRPV4 ion channel…
The team designed a 'choice chamber' (a device that offers small invertebrates two or more contrasting conditions and allows them to move freely towards the…
The development could ultimately lead to molecular systems that might one day be used for medical therapeutic devices and molecular-scale reconfigurable…
