Trees are one of humans' biggest allies in the fight against climate change, soaking up around 30% of the carbon we pump into the atmosphere by burning fossil fuel.
Methane fluxes from lakes are considerably higher during the day than the night, according to a study conducted by LiU researchers. Consequently, the research group says that the contribution of northern lakes to global methane emissions is 15% lower than previously estimated. The study is published in PNAS, Proceedings of the National Academy of Sciences.
A new collaborative study led by researchers from the Spanish National Research Council (CSIC) at the Centre for Research in Agricultural Genomics (CRAG) in Barcelona and the Institute for Plant Molecular and Cellular Biology (IBMCP) in Valencia describes a promising strategy to improve the nutritional benefits of crops.
Denver is known for its relatively mild climate and its four distinct seasons. It's also known for its temperature fluctuations over the course of a day or even hours. But what does that mean for the city's residents—and for that matter, the rest of the inhabitants of the continental United States when it comes to temperature extremes?
We've known from the beginning how the end will arrive. Eventually, the coronavirus will be unable to find enough susceptible hosts to survive, fading out wherever it briefly emerges.To achieve so-called herd immunity -- the point at which the virus can no longer spread because there are not enough vulnerable humans -- scientists have suggested that perhaps 70% of a given population must be...
A study showed that patients receiving messages from a chatbot used a third fewer opioids after fracture surgery, and their overall pain level fell, too.
Scientists in geomagnetic, geophysics, and heliophysics research groups observe and model the SAA, to monitor and predict future changes - and help prepare for future challenges to satellites and humans in space.

Several years ago, planetary scientist Lynnae Quick began to wonder whether any of the more than 4,000 known planets beyond our solar system might resemble some of the watery moons around Jupiter and Saturn. Though some of these moons don’t have atmospheres and are covered in ice, they are still among the top targets in NASA’s search for life beyond Earth. Saturn’s moon Enceladus...
Thomas Brück saw the sea whip Antillogorgia elisabethae for the first time 17 years ago while diving on a research trip to the Bahamas. He still remembers this encounter vividly, which took place 18 meters below the water's surface: "Their polyp-covered, violet branchlets moved gently in the current. A fascinating living organism!" As it also contains various biologically active compounds, the...
Running into an unseen spiderweb in the woods can be scary enough, but what if you had to worry about a spiderweb—and the spider—being catapulted at you? That's what happens to insects in the Amazon rain forests of Peru, where a tiny slingshot spider launches a web—and itself—to catch unsuspecting flies and mosquitoes.
Although Live Oak trees are common in South Florida today, Ken Feeley, a University of Miami biology professor, said their time here may be fleeting. With climate change pushing up temperatures, the oaks, which favor cooler conditions, could soon decline in the region and be replaced with more tropical, heat-loving species such as Gumbo Limbo or Mahogany trees.
