In a finding that once again displays the power of the female, UCSF neuroscientists have discovered that teenage male songbirds, still working to perfect their song, improve their performance in the presence of a female bird.
The finding sheds li…
Researchers at the University of Illinois at Chicago have discovered a signaling mechanism in the bacterial ribosome that detects proteins that activate genes for antibiotic resistance.
“The ribosome is one of the most complex molecular machines i…
A team made up of members of the University of Oviedo (UO) and the Complutense University of Madrid (UCM) have gathered together all findings of the woolly mammoth, the woolly rhinoceros and the reindeer in the Iberian Peninsula to show that, …
Detecting the presence of hazardous lead paint could become as simple as pressing a piece of paper against a wall and noting a color change. Scientists at the University of Illinois at Urbana-Champaign have developed a highly sensitive and selective biosensor that functions in much the same fashion as a strip of litmus paper.
Coots, the Rodney Dangerfields of the bird world, just might start to get some respect as a result of a new study showing that these common marsh birds are able to recognize and count their own eggs, even in the presence of eggs laid by other birds.
The counting ability of female coots is part of a sophisticated set of defense mechanisms used to thwart other coots who lay eggs in their neighbors’ nests, according to Bruce Lyon, an assistant professor of ecology and evolutionary biology at the University of California, Santa Cruz. Lyon studied hundreds of coot nests in British Columbia during a four-year investigation. His latest findings appear in the April 3 issue of the scientific journal Nature.
