Dietary supplement many not lower prostate cancer risk

COLUMBUS, Ohio A tomato a day may help keep prostate cancer at bay -- but a widely used dietary supplement derived from tomatoes may not be sufficient. That's the conclusion of the first animal study comparing the cancer-preventing potential of tomato products to that of lycopene, a substance ...

It's feast or famine: Predators may drive lemming cycles, Science researchers say

...a peak lemming year, the generalist predators help keep the rapidly multiplying lemmings in check until the stoat numbers can catch up. At that point, predation is intense enough to drive the lemming numbers down to the low point in the cycle. Once the three generalists have turned to alternative, more p...

But that is not the best approach, according to the research findings. In the new method, the largest products that can be quickly disassembled...

Mathematical modeling predicts cellular communication

...Proteins act as molecular switchboard operators to keep the lines of communication open and the flow of cellular messages on track. But charting the protein interactions, signaling pathways, and other elements that regulate these networks is no small feat. There are many players that interact in complicat...

New gene necessary for plant growth and development discovered

... previously unknown gene, SIR1, which functions to keep the effects of auxin in check. The UCSD scientists say that one implication of their discovery is the potential development of environmentally safe herbicides from chemicals that impede the action of auxin by over-activating the SIR1 gene. A paper fe...

Beyond genes: Scientists venture deeper into the human genome
