Hairy nanoparticles put viruses in a deadly embrace
Current drugs can’t stop viruses for good. But newly developed hairy nanoparticles just might. They surround and put pressure on the viruses, which ultimately destroys them.

New ‘tattoo’ could lead to drought-tolerant crops
Scientists create stick-on 'plant tattoo.' It measures how efficiently crops use water, a key to better identifying breeding stock for more drought-resistant crops.
