Research focusing on why estrogenic hormones produce differing results

...n the context of a larger gene region dramatically reduces transcription. Her lab's findings also supported previous evidence that ER-alpha is much more potent than ER-beta. "Turning on the expression of genes in a cell is not like turning on a light switch, because you have many different estrogen responsi...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

...ds of closure are (1) such discontinuous breathing reduces water loss and (2) it enables insects to rid their bodies of carbon dioxide, respiration's byproduct, when the insects are underground. As is true for miners, insects, while underground, are faced with high-carbon-dioxide and low-oxygen amounts, nece...

Study shows naturally occurring proteins protect against rapid tumor growth

...n, confers protection against cancer in mice, i.e. reduces the growth rate of tumors by 300 percent," Folkman adds. "Between nine and 10 million people worldwide die of cancer each year," says Kalluri. "While a lot has been learned of how genetic defects convert normal cells into cancerous cells, much less i...

Scientists discover how climate change causes the simultaneous boom or bust of multiple populations

...astrointestinal nematode, Trichostrongylus tenuis, reduces the reproductive success of the Red Grouse by causing the hen to lay fewer eggs and by reducing the likelihood that those eggs will hatch. His earlier research also had shown that climate conditions can influence both the transmission of the parasit...

Foiling fugitive fish

...emselves on the opposite coast, this substantially reduces the likelihood that they will ecologically overwhelm local salmon populations. With the rapid growth of ocean fish farming along the world's coastlines, and a general desire to limit the ecological impact of this activity, Dr. Fleming says there's pr...

New findings lead researchers to question basic assumptions of fisheries management

...ever, elimination of older generations drastically reduces the ability of the population to replenish itself. Failure to account for the role of older fish in maintaining healthy populations may help explain the recent collapse of some major West Coast fisheries. The Pacific Fishery Management Council has d...

Celebrex provides a two pronged attack against prostate cancer

...he name Celebrex, not only targets COX-2, but also reduces levels of a key protein, cyclin D1, that's critical for cell replication. "It is well established that COX-2 is a significant and rational target for anti-cancer therapy," said Andrew Dannenberg, M.D., director of cancer prevention at the Weill Medic...

Finding hidden invaders in a Hawaiian rain forest

...the aircraft-based analysis discovered that ginger reduces the amount of nitrogen in the Metrosideros forest canopy--a discovery that was later corroborated by ground-based sampling. Peter Vitousek from Stanford University, who coauthored the paper, commented: "This is the first time where remote sensing sh...

Light therapy may combat fungal infections, new evidence suggests

...r that light response. Loss of the same genes also reduces fungal virulence in mice, they reported. Earlier studies had linked the genes to light-sensing in another distantly related fungal lineage, an indication that the fungal light sensor arose early in evolution and may be shared by many extant fungal sp...

...d the soybean aphid. The soybean aphid, which also reduces yield in soybeans, has been found in all of the 33 major soybean-producing counties. More than 3,000 acres in Virginia had to be treated in 2004 with insecticide to prevent losses, said Ames Herbert, Virginia Cooperative Extension entomologist at the...

TEL2 gene cooperates with MYC gene to provoke B-cell lymphomas

...This situation occurs when increased TEL2 activity reduces the cell's ability to trigger apoptosis in response to relentless prodding by MYC to keep multiplying. As the process of apoptosis becomes sluggish, the population of B lymphocytes increases. The greater the number of these cells, the more likely som...

Fewer fish discarded after individual transferable quotas offered

The study in Canada's British Columbia waters compared so-called individual transferable quotas with a previously used system of trip limits where vessels are only allowed to land a certain quantity of each speci...
