Blind tadpoles were able to process visual information from eyes grafted onto their tails after being treated with a small molecule neurotransmitter drug that augmented innervation, integration, and function of the transplanted organs, according to a paper published online today by researchers at the Allen Discovery Center at Tufts University in npj Regenerative Medicine, a Nature Research journal. The work,…
With honeybee colony health wavering and researchers trying to find technological ways of pollinating plants in the future, a new Georgia Tech study has looked at how the insects do their job and manage to stay clean. According to the study, a honeybee can carry up to 30 percent of its body weight in pollen because of the strategic spacing…
Cells are basically tiny computers: They send and receive inputs and output accordingly. If you chug a Frappuccino, your blood sugar spikes, and your pancreatic cells get the message. Output: more insulin. But cellular computing is more than just a convenient metaphor. In the last couple of decades, biologists have been working to hack the cells’ algorithm in an effort…
Brain size in primates is predicted by diet, an analysis by a team of New York University anthropologists indicates. These results call into question “the social brain hypothesis,” which has posited that humans and other primates are big-brained due to factors pertaining to sociality. The findings, which appear in the journal Nature Ecology and Evolution, reinforce the notion that both human…
A team spanning Baylor College of Medicine, Rice University, Texas Children’s Hospital and the Broad Institute of MIT and Harvard has developed a new way to sequence genomes, which can assemble the genome of an organism, entirely from scratch, dramatically cheaper and faster. While there is much excitement about the so-called “$1000 genome” in medicine, when a doctor orders the…
Researchers at Beth Israel Deaconess Medical Center (BIDMC) have gained new insight into the genetic and neuronal circuit mechanisms that may contribute to impaired sociability in some forms of Autism Spectrum Disorder. Led by Matthew P. Anderson, MD, PhD, Director of Neuropathology at BIDMC, the scientists determined how a gene linked to one common form of autism works in a…
