Secret channel holds key to metabolic mysteries
Researchers use cloned gene to reveal how cells transmit vital elements Biologists have discovered a "channel" that allows key elements such as calcium and magnesium to enter living cells. The research, published in the May 31 issue of the journal Nature, provides new insight into th...UNC, Penn State scientists find gene that controls water retention in plants

...latest figures on in vitro fertilization in Europe reveal the welcome news that while the number of IVF treatment cycles has increased, the number of multiple births is decreasing. Dr Karl Nygren and Dr Anders Nyboe Andersen told the European Society of Human Reproduction and Embryology annual meeting in La......at aligning the human and mouse DNA sequence might reveal many more genes," Stubbs said. "However, if chromosome 19 is indicative of other chromosomes, the estimate of 30,000 genes is fairly accurate." Before the comparison of human and mouse DNA, researchers had thought that human chromosome 19 had ...Gene link to increased risk of coronary heart disease, found by scientists

Second, they caution that their work should not be applied to the desert tortoise, in part because the Texas tortoise evolved in presence of large grazers such as bison ...Salmon life stories recorded in strontium

This discovery could reveal whether certain rivers or tributaries produce fish that are more likely to survive their time in the ocean and successfully make the return trip to spawn in the stream where they hatched.
