 Micro RNAs And Musculature
In an effort to understand the biological function of the microRNA mir1, Drs. Nicholas Sokol and Victor Ambros (Darmouth Medical School) have studied the expression profile, transcriptional regulation and loss-of-function phenotype of Drosophila mir-1 (Dmir-1). Strikingly, their study shows that, in Drosophila embryos, mir-1 expression is not required for mesodermal cell fate decisions or cell proliferation during embryogenesis, but rather, that it appears to act to reinforce and maintain cell identity during times of rapid growth. The Omnificent English Dictionary In Limerick Form (OEDILF)
Limericks, or so we've been told/Are sometimes quite hard to behold./The text may be naughty,/Or downright plain bawdy;/On this site, all types will unfold. "As an international writing project, our limericks frequently use local spellings, grammar, punctuation and, most likely, rhymes that may not be familiar to all readers."Project is in early stages; expect gaps. From limerick writers in over a dozen countries where English is spoken. Past regional cold and warm periods linked to natural climate drivers
Intervals of regional warmth and cold in the past are linked to the El Niño phenomenon and the so-called "North Atlantic Oscillation" in the Northern hemisphere's jet stream, according to a team of climate scientists. These linkages may be important in assessing the regional effects of future climate change. Environmental Chemicals Found In Breast Milk And High Incidence Of Tes
A comparison of breast milk samples from Denmark and Finland revealed a significant difference in environmental chemicals which have previously been implicated in testicular cancer or in adversely affecting development of the fetal testis in humans and animals. Astronomers Detect Powerful Bursting Radio Source
Astronomers at Sweet Briar College and the Naval Research Laboratory (NRL) have detected a powerful new bursting radio source whose unique properties suggest the discovery of a new class of astronomical objects. Worms Take The Sniff Test To Reveal Sex Differences In Brain
Buttery popcorn or fresh green vegetables? Your answer tells a lot about you. Now, scientists say that the way that thousands of tiny worms have answered that question likely reveals a lot about you and your brain, too. Polar Bears Threatened By Hunting Policy Favoring The Killing Of Male
Policies that encourage hunters to go after male polarbears in order to conserve females, could make it harder for the animals to find mates. Researchers determined there is a critical threshold in the male-to-female ratio. Below it, their model predicts a sudden and rapid collapse in fertilization rates. Walnuts' Secret Defense Explored
With their rich taste and pleasing crunchiness, it's no wonder that walnuts are one of America's favorite tree nuts. But walnuts, like several other kinds of crops, are vulnerable to attack by fungi called Aspergillus flavus and A. parasiticus. Both species can produce a natural compound called aflatoxin, which is thought to be carcinogenic. Hatchery-raised salmon too crowded
Every year, large numbers of hatchery-raised young salmonids are released into Swedish rivers and streams to compensate for losses in natural production. Butthese fish generally survive poorly in the wild. Researchers have discovered why: the young fish are too crowded at the hatchery.
