Cigarette smoke alters DNA in sperm, genetic damage could pass to offspring

...xposed to two cigarettes per day, the equivalent – based on blood levels of tobacco by-products – of an average human smoker, according to research previously published by one of the study's co-authors. Yauk and her colleagues found that the rate of Ms6-hm mutations in the smoking mice were 1.4 times hi...

CSIRO scientists join fight to save 'Tassie devil'

The finding of the new LCA gene, based on work funded by the Wellcome Trust and local charity Yorkshire Eye Research, appears in this month's edition of the journal Nature Genetics. The newly-discovered gene, LCA5, is involved in the production of lebercilin, an essential component of ...

Now, self-healing materials can mimic human skin, healing again and again

...vercome by implementing a new microvascular design based on dual networks, the researchers suggest. The improved design would allow new healing chemistries – such as two-part epoxies – to be exploited, which could ultimately lead to unlimited healing capability. “Currently, the material can heal cracks i...

Research finds that circadian rhythms dominate all life functions

...shows that the function of all genes in mammals is based on circadian -- or daily -- rhythms. The study, publishing in PLoS Computational Biology on June 15, refutes the current theory that only 10 percent to 15 percent of all genes were affected by nature's clock. While scientists have long known that cir...
