Experiments provide proof of how traveling in groups protects insects

...ntists can predict and possibly change the path of massive insect bands, he said. "In the United States nowadays, Mormon crickets just cost farmers and others a lot of money, but in parts of Africa and elsewhere, locusts can cause widespread famine because they consume crops, and the people there sometimes ...

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

... the HOX genes appear to be turned on in groups by massive numbers of tags. HOX genes also are deeply involved in cancer, making the findings particularly important. Some of the proteins that regulate HOX genes are capable of causing or suppressing tumors. Technological breakthrough Bernstein has been stu...

...uch shorter reaction times, and the possibility of massive parallel processing. In general, this should lead to increased throughput and, thus, to reduced cost of (bio)chemical analysis. In addition, such integrated labs-on-a-chip have many potential applications in biomedicine and bioengineering. In the con...

Researchers discover molecule that causes secondary stroke

...ospasm usually occurs three to 10 days following a massive brain bleed known as hemorrhagic stroke. Sixty percent of patients who survive the initial stroke develop vasospasm, and 40 percent of them die from it. Vasospasm, says neurology department researcher Joseph Clark, PhD, results from a buildup of tox...

Surprising findings reported about iron overload

...EJM paper is the first report from analysis of the massive data arising from the study, called the Hemochromatosis and Iron Overload Screening (HEIRS) Study.

Survey finds silver contamination in North Pacific waters

...open ocean is vastly diluted, so there may be some massive hotspots of silver contamination around the Asian continent. That's where effects on marine organisms would occur," Luoma said. In San Francisco Bay, silver and copper from industrial discharges reached such high levels in the 1970s and early 1980s ...

Small species back-up giant marsupial climate change extinction claim

...inction of Darling Downs megafauna was caused by a massive shift in climate rather than by the arrival of humans who over hunted animals or destroyed habitats by burning the landscape. The findings, which were unearthed with the help of amateur fossil hunter, Ian Sobbe, are of particular significance becaus...

Defenseless plants arm themselves with metals

...tinuously elevated, a plant thinks it's under some massive attack by a pathogen. It's expressing all its pathogen response proteins, and at such a high level, they can have a deleterious effect on the plant." Metal hyperaccumulators like Thlaspi, however, don't show any negative effects from their constant ...

Two chemicals boost immune cells' ability to fight HIV without gene therapy

...ontinue performing their protective functions. The massive amount of division prematurely shortens these cells' ends, or telomeres, ultimately exhausting the immune system. UCLA's previous research shows that telomerase rejuvenates the telomeres and allows the immune cells to remain youthful and active as t...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...se their ability to mutate, even when subjected to massive amounts of ultraviolet light. This brought Romesberg to the conclusion that mutation is a programmed stress response -- a survival mechanism. If the cell senses damage, and if the damage persists beyond its ability to repair it, the cell will turn o...
