Arctic spring comes weeks earlier than a decade ago
06-18-2007 · EurekAlert!In the Earth's cold and icy far north, the harsh winters are giving way to spring weeks earlier than they did just a decade ago, researchers have reported in the June 19 issue of Current Biology, published by Cell Press. The finding in the Arctic, where the effects of global warming are expected to be most severe, offers an "early warning" of things to come on the rest of the planet, according to the researchers.

- Evidence underlying repeated courses of steroids for preterm birth is unsound
07-12-2007 · EurekAlert!
Researchers in this week's BMJ question whether giving repeated courses of steroid drugs to mothers at risk of preterm delivery is based on sound evidence.Babies born before 32 weeks of pregnancy often have neonatal lung disease, a major cause of illness and death -- the earlier the birth, the greater the risk.

- Newly discovered virus linked to deadly skin cancer
01-17-2008 · EurekAlert!
Painstaking screening of DNA sequencing data has revealed a previously unknown virus that appears to be strongly associated with a rare but deadly skin cancer called Merkel cell carcinoma, researchers from the University of Pittsburgh Cancer Institute report in this week's issue of the journal Science. In the paper, the researchers, who found the cause of Kaposi's sarcoma, also describe a nearly decade-long effort to harness the sequencing technology to identify Merkel cell polyomavirus.

- Insulin grown in plants relieves diabetes in mice; UCF study holds promise for humans
07-30-2007 · EurekAlert!
Professor Henry Daniell's research team genetically engineered tobacco plants with the insulin gene and then administered freeze-dried plant cells to five-week-old diabetic mice as a powder for eight weeks. By the end of the study, the diabetic mice had normal blood and urine sugar levels, and their cells were producing normal levels of insulin.

- South Dakota's abortion ban is a threat to women's health
10-26-2006 · EurekAlert!
In this week's BMJ, a senior doctor raises serious concerns over abortion law in the US state of South Dakota.Earlier this year, South Dakota passed a bill which bans virtually all abortions in the state except for circumstances in which the procedure is necessary to "prevent the death of the mother." Under this new legislation, doctors face prosecution for the termination of any pregnancy in which maternal death is not clearly averted by its performance.

- Shrinking ponds signal warmer, dryer Alaska
10-12-2006 · EurekAlert!
A first-of-its kind analysis of 50 years of remotely sensed imagery from the 1950s to 2002 shows a dramatic reduction in the size and number of more than 10,000 ponds in Alaska. The analysis, by University of Alaska Fairbanks scientists and published this week in the Journal of Geophysical Research, indicates that these landscape-level changes in arctic ponds are associated with recent climate warming in Alaska and may have profound effects on climate and wildlife.

- A review of microcantilevers for sensing applications
06-21-2007 · EurekAlert!
Microelectromechanical Systems (MEMS) have come into existence only in the last decade. Microcantilevers are the most simplified MEMS based devices. They are of significant interest as they have potential applications in every field of science ranging from physical and chemical sensing to biological disease diagnosis.

- Pollinators help one-third of the world's food crop production
10-25-2006 · EurekAlert!
Pollinators affect 35 percent of the world's food crop production, increasing the output of 87 of the leading crops worldwide, finds a new study co-authored by a UC Berkeley conservation biologist. The study is the first global estimate of food crop production that is reliant upon animal pollination. It comes one week after a National Research Council report detailed the troubling decline in populations of key North American pollinators.
