Tropical dry forests receive international recognition

... private conservation, says Sanchez-Azofeifa. This tactic means convincing governments to realize the value of conserving tropical dry forest land and in turn, paying the land owners environmental services fees in exchange for a promise the land won't be used for commercial development. Costa Rica is a lead...

Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

...cer-killing properties when used together. This tactic focuses on two main ingredients: structures called "nanoshells," which are microscopic balls consisting of a silica core coated with a thin layer of gold and, secondly, near infrared light (NIR). Used alone, nanoshells are non-toxic and can be excret...

Dominant meerkats render rivals infertile

... stress hormones and a collapse in fertility. This tactic reduces conception rates and increases abortion rates among the evicted subordinates, who are only allowed to return to the group after the dominant female has given birth. The dominant female benefits in two ways from reducing the fertility of h...

UGA scientists engineer root-knot nematode resistance

...The most cost-effective and sustainable management tactic for preventing root-knot nematode damage and reducing growers' losses, he said, is to develop resistant plants that prevent the nematode from feeding on the roots. Because root-knot nematode resistance doesn't come naturally in most crops, Hussey's g...

'Erectile dysfunction' drugs heighten natural anti-cancer activity

...mponents. The new Hopkins study homes in on a tactic used by cancers to avoid detection by the immune system by turning elements of that system to its own advantage, says Ivan Borrello, M.D., assistant professor at the Johns Hopkins Kimmel Cancer Center. Borrello and his colleagues found that tumor...

Wheat can fatally starve insect predators

...ns would enable the scientists to use the promoter tactic only in the vegetative parts of the wheat plant rather than in the head or grain portions. This will protect the grain quality and the consumer. "Once we understand which genes are active and the timing of the interactions, we can really understan...
