Nanoparticles: size and charge matter
Nanoparticles can be designed for targeted delivery of drugs or genes into the body. New work reveals details of how blood proteins respond to these particles.

FDA releases guidelines for genetically modified animals
Draft rules lay out policies for approving altered animals, including those used for food.

A ‘novel’ chemistry to make fuel from sugar
It’s not alchemy, but it might sound like it: a new way to transform sugars from plants into gasoline, diesel or even jet fuel by passing the sugars over exotic materials.

Good day care grime
A study of 952 children in Manchester, England, suggests that children going to day care starting at age 6 months could be less likely to develop asthma later.

Potent Promise: Back to the Womb
Reverting adult cells to an embryonic state without creating embryos is a tricky business.

Live long and alter
Yeast cells fed a calorie-restricted diet live longer and have just as much energy as those fed a normal diet.
- Life
Finding health in fragility
A unifying principle for protein networks' weaknesses could aid development of new drugs.

Stem cells, show your face
As researchers develop ways of reprogramming adult cells, such as skin cells, to have the same flexibility as embryonic stem cells, this new test shows that the reprogrammed stem cells are truly capable of becoming any cell in the body.

Carbon caveat
Adding carbon compounds to some ocean systems may lead to a counterintuitive drop in their overall carbon content — and how much carbon dioxide the ocean could store.

Finding the golden genes
Advances in gene therapy could tempt some athletes to enhance their genetic makeup, leading some researchers to work on detection methods just in case.
