In one of the first efforts of its kind, UCLA researchers have taken mammalian genome maps, including human maps, one step further by showing not just the order in which genes fall in the genome but which genes actually interact.
The findings, published in the August issue of the journal Genome Research, will [...]
A Columbia scientist has become the first to grow a complex, full-size bone from human adult stem cells.
Gordana Vunjak-Novakovic, a professor of biomedical engineering at the Fu Foundation School of Engineering and Applied Science, reports that her team grew a temporomandibular joint (TMJ) from stem cells derived from bone marrow. Her [...]
Researchers at Washington University School of Medicine in St. Louis have peered deep into the eye of the chicken and found a masterpiece of biological design.
Scientists mapped five types of light receptors in the chicken’s eye. They discovered the receptors were laid out in interwoven mosaics that maximized the chicken’s ability to see many colors [...]
Antiviral drugs block influenza A viruses from reproducing and spreading by attaching to a site within a proton channel necessary for the virus to infect healthy cells, according to a research project led by Iowa State University’s Mei Hong and published in the Feb. 4 issue of the journal Nature.
Hong, Iowa State’s John D. Corbett Professor [...]
Only some bats and toothed whales rely on sophisticated echolocation, in which they emit sonar pulses and process returning echoes, to detect and track down small prey. Now, two new studies in the January 26th issue of Current Biology, a Cell Press publication, show that bats’ and whales’ remarkable ability and the high-frequency hearing it depends [...]
It’s not thinking in the way humans, dogs or even birds think, but new findings from researchers at the University of Tennessee, Knoxville, show that bacteria are more capable of complex decision-making than previously known.
The discovery sets a landmark in research to understand the way bacteria are able to respond and adapt to changes in [...]
Tiny insects could be as intelligent as much bigger animals, despite only having a brain the size of a pinhead, say scientists at Queen Mary, University of London.
“Animals with bigger brains are not necessarily more intelligent,” according to Lars Chittka, Professor of Sensory and Behavioural Ecology at Queen Mary’s Research Centre for Psychology and University [...]
Familiar beans like reds, whites and pintos are rich in iron, a nutrient essential for our health. But not all of the little legumes’ treasure trove of iron is bioaccessible—that is, available for our bodies to readily absorb.
In ongoing investigations, Agricultural Research Service (ARS) animal physiologist Raymond P. Glahn and Cornell University co-investigators are discovering [...]
Hikers know that moss on a tree trunk always points north. According to new research by Israeli and German scientists, this ancient plant may also provide a new “compass” for stem cell research, telling scientists how better to program stem cells for medical purposes.
Dr. Nir Ohad of Tel Aviv University’s Department of Plant Sciences and [...]
Alexis Webb enters a small room at Washington University in St. Louis with walls, floor and ceiling painted dark green, shuts the door, turns off the lights and bends over a microscope in a black box draped with black cloth. Through the microscope, she can see a single nerve cell on a glass cover slip [...]
