Climate Change Might Steal Nutrients from Food Crops

2017 was a good year for worrying about nutrient losses that might come with a changing climate. The idea that surging carbon dioxide levels could stealthily render some major crops less nutritious has long been percolating in plant research circles. “It’s literally a 25-year story, but it has come to...

How Disasters Spur Scientific Research

Every day, it seems like there’s a new natural disaster in the headlines. Hurricane Harvey inundates Texas. Hurricane Irma plows through the Caribbean and the U.S. south, and Jose is hot on its heels. A deadly 8.1-magnitude earthquake rocks Mexico.

Plants can counter human emissions

Under right conditions, photosynthesis-respiration cycle stems accelerating rise of atmospheric gas Plants temporarily halted the acceleration of rising carbon dioxide concentrations in the atmosphere, new research suggests. From 2002 through 2014, CO2 levels measured over the oceans climbed from around 372 parts per million to 397 parts per million. But the average...

DNA can now store images, video and data

A Possible Ninth Planet Beyond Neptune

The solar system may host a ninth planet that is about 10 times bigger than Earth and orbiting far beyond Neptune, according to a research published recently. Computer simulations show that the mystery planet, if it exists, would orbit between about 200 and 1,000 times farther from the sun than...
