Creating A New Approach To Archiving Human Genetic Information

ScienceDaily - 8 min 8 sec ago
How a genomic code is deciphered is traditionally left to professional annotators who use information from a number of sources (for instance, knowledge about similar genes in other organisms) to work out where a gene starts, stops and what it does. Even the "gold standard" of professional annotation is an exceptionally slow process. However, new technology may provide a faster solution.

Slow Exercise (Not Fast) Is Better For Menopausal Women

ScienceDaily - 8 min 8 sec ago
As we get older, our muscles deteriorate and we become weaker, which has serious implications. We become clumsier and begin to have more falls, often resulting in broken bones or even more severe injuries. Researchers are examining the effects of different exercise regimes in menopausal women, with the aim of developing new strategies for delaying and reducing the initial onset of age related muscle deterioration.

Study Shows Rise In Cornwall's Dolphin, Whale, And Porpoise Deaths

ScienceDaily - 8 min 8 sec ago
A new study has revealed a disturbing rise in the number of whales, dolphins and porpoises found dead on Cornish beaches. The frequency of these mammals, collectively known as cetaceans, found stranded on beaches in Cornwall has increased with a sharp rise in the last eight years. After analyzing nearly 100 years of data, the researchers believe this could, in part, be due to more intensive fishing.

Normal-looking Sperm May Have Serious Damage; Scientists Urge More Care In Selection

ScienceDaily - 3 hours 8 min ago
Intracytoplasmic sperm injection (ICSI) where a single sperm is injected into an egg to fertilize it, is increasingly used to help infertile men father children. Although the sperm chosen for the procedure may appear quite normal, researchers in the US have found that many of them in fact have DNA damage, which can decrease the chances of pregnancy and increase chances of later miscarriage if pregnancy does occur. In infertile men, between 20 and 66% of normal-looking sperm had DNA damage.
