How IVF could be causing genetic errors in embryos

... studies are important for better directing future resources and studies in humans. But we must remember that these are preliminary results in a mouse model, and they need to be repeated and confirmed in other strains of mice before translating to studies in humans." Other research has suggested that culturin...

Brazil creates buffer zone around coral reefs off Atlantic coast

... small islands, coral and algal reefs. Its natural resources directly support more than 100,000 people. Since 1996, CI-Brazil has conducted biological monitoring at Abrolhos National Marine Park, including assessments of the effects of oil and gas exploration and possible oil spills that helped motivate the e...

Protein clue to tailor-made antibiotics

...ike E. coli frequently try to kill each other when resources are scarce using protein antibiotics called colicins, which are potent toxins. The research led by Professor Colin Kleanthous has discovered a critical element in the mode of action of a class of colicins (so-called DNases) that kill cells by dest...

Proteins spur diabetic mice models to grow blood vessels, nerves

...years. If Netrins prove to be a viable therapy and resources are committed to drug development, a netrin-based therapy could be on the market in 10 years, Li said. Netrins are one of four major classes of neural guidance cues, which induce axons or nerve fibers to extend in specific directions during develo...

'Scent of a woman' tells male redback spiders to find a mate
