Crops could get nutrient boost from nanoparticles
Nanoparticles typically used to treat cancer in humans could be used to deliver nutrients to malnourished plants. Crops are better able to absorb fertilizing nutrients delivered by liposomes than from traditional nutrient spray.
Tiny robot uses laser power to fly
A tiny flying robot called RoboFly uses laser light and an onboard circuit to power its flight and free it from the lines connected to batteries that powered its predecessors.
Agriculture, languages brought to Southeast Asia by ancient Chinese
Ancient Chinese farmers spread south into Southeast Asia, bringing rice farming and new languages to the region around 4,000 years ago, a new DNA study published in Science suggests. Analysis of 4,000-year-old skeletons indicates the migrating farmers mated with hunter-gatherers in Southeast Asia, supporting archaeological evidence of the migration.
Hurricane Harvey study suggests future storms may be more intense
Researchers studying Hurricane Harvey, which struck the Houston area last year, say the data they’ve collected suggest future storms may last longer and be more intense. Among other findings was data showing that the energy Harvey picked up from the ocean was equivalent to the energy it released when it made landfall.
