MU researchers to study the status of black bears in Missouri

...ct DNA from the hair follicles and use that DNA to estimate the number of bears, the gender ratio of male to female bears, where the bears are migrating from and if they are reproducing. “This study is a good example of the use of cutting-edge molecular biology in the management of Missouri’s wildlife,” E...

Scientists close in on missing carbon sink

...year, which is almost 1 billion tons less than the estimate produced by the computer models. The scientists also found that intact tropical ecosystems are a more important carbon sink than previously thought. The models had generally indicated that tropical ecosystems were a net source of 1.8 billion tons ...

Corals -- More complex than you?

...o yet. "Based on the rate of gene discovery, we estimate that corals have as many as 20 or 25,000 genes, compared with the human complement of 20-23,000." Why a simple creature should have such a huge genetic repertoire is a mystery, but scientists are excited by it because corals are near the root of t...

New technique will produce a better chromosome map

To improve chromosome spreading, researchers use a rotary tool that vibrates the coverslip surface for several minutes. A simple mechanical vise applies up to two to...

Paper challenges 1491 Amazonian population theories

...pulation estimates were 1 million, in the 70s that estimate drifted up to 4 million; and in the 1990s drifted up to 10 million. "We've now got a polarized community," he says. At one end, he says, is Anna Roosevelt of the Field Museum in Chicago (she argues for large populations dispersed throughout Ama...

Despite their heft, many dinosaurs had surprisingly tiny genomes

...riation in genome size across animal species. They estimate that active repetitive DNA might have comprised an average 12 percent of the ornithischian genome but just 8.4 percent of theropod genetic constitution. The work indicates that the small genomes typically associated with birds -- whose genetic com...

They then utilize their results to project future levels of stressors. Restricting their data to countries of at least one million people, Diet...

However, in order to estimate future changes, it is essential to develop a deeper understanding of the effect of water temperature on the biology of organisms under question. A new investigation, just published in the scientific journal Science, reveals that a warming induced def...

Growth hormone is not the anti-aging bullet for healthy adults

The Web is replete with ads for all kinds of products said to contain GH, from pills, sprays, injections, secretagogues, homeopathic formations, and GH r...

Gene expression test reveals ER and HER-2 status of breast tumors
