As a transition between winter and spring in the U.S., March is the kind of month where just about any type of weather can happen. Coming off a very warm February 2017, many of us were tricked into thinking spring had arrived. However, an Arctic plunge of frigid air plowed into the nation’s midsection in mid-March, dashing hopes of an early spring and freezing plants as far south as Florida.
This is a composite image of Uranus by Voyager 2 and two different observations made by Hubble — one for the ring and one for the auroras.
Ever since explorer William Beebe descended into the depths in a metal sphere in the 1930s, marine biologists have been astounded by the number and diversity of glowing animals in the ocean. Yet few studies have actually documented the numbers of glowing animals at different depths. In a new study in Scientific Reports, MBARI researchers Séverine Martini and Steve Haddock show that three quarters of the animals in Monterey Bay waters between the surface and 4,000 meters deep can produce their own light.
A fresh wave of logging is hitting America's national forests, writes Brett Haverstick. But this time it's all for the sake of 'forest health' and 'fire prevention'. It might look like industrial clear-cutting to you and me, but really, it's in a good cause. And if the forests and precious ecosystems they harbor just happen to perish in the process ... well ain't that just too bad?
Plants are currently removing more CO2 from the air than they did 200 years ago, according to new work from Carnegie’s Joe Berry and led by J. Elliott Campbell of UC Merced. The team’s findings, which are published in Nature, affirm estimates used in models from the Intergovernmental Panel on Climate Change.
Plants take up carbon dioxide as part of the process of photosynthesis—a series of cellular reactions through which they transform the Sun’s energy into chemical energy for food. This research from Campbell, Berry, and their colleagues constructs a new history of global changes in photosynthetic activity.
NASA's Aqua satellite provided a birds-eye view of Tropical Cyclone Ernie as it was being battered by strong vertical wind shear and torn apart.
