More than 45 million people across 14 Southern states are now in the midst of what's being called a "flash drought" that's cracking farm soil, drying up ponds and raising the risk of wildfires, scientists said Thursday.

More than 5,500 species of birds, mammals, amphibians and reptiles are bought and sold on the worldwide animal market, a volume that is around 50 percent higher than earlier estimates, a study published in Science said Thursday.
Stable metal organic frameworks are prized for their ability to capture carbon dioxide or harvest atmospheric water, but U-M researchers have developed a use for unstable metal organic frameworks: as a system for drug delivery.
Interspecific feeding—when an adult of one species feeds the young of another—is rare among songbirds, and scientists could only speculate on why it occurs, but now, Penn State researchers have new insight into this behavior.
New research from Cornell University shows that plants can communicate with each other when they come under attack from pests.
The old saying that people marry their parents may be true for poison dart frogs, and it may even lead to the formation of new species, according to a new study in Nature based on work at the Smithsonian Tropical Research Institute (STRI).
NASA's Terra satellite passed over the Sea of Japan on Oct. 3 and captured a visible image of Tropical Storm Mitag. Clouds associated with the storm blanketed the Sea of Japan and satellite imagery indicated the storm was becoming extra-tropical.
A father holds up his newborn, their faces only inches apart, and slowly repeats the syllables "da" and "dee." After months of hearing these sounds, the baby begins to babble and gradually "da da da" is refined to the word "Daddy."
New insights on how subunits of the influenza virus polymerase co-evolve to ensure efficient viral RNA replication are provided by a study published October 3 in the open-access journal PLOS Pathogens by Nadia Naffakh of the Institut Pasteur, and colleagues. As the authors note, the findings could lead to novel strategies for antiviral drug development.
Wildfires are natural hazards that are becoming more intense and extensive with climate change. Scientists have previously described what major transformations should take place to contend with these fires, including the need to adapt to more fire on the landscape, change the way communities are designed, allow for more prescribed fire and thin fuels like brush and smaller trees.
Scientists have long understood that forest biodiversity is driven in part by something called rare-species advantage—that is, an individual tree has a better chance of survival if there are only a few other trees of the same species around. As a result, when the number of trees of any given species rises, survival rates among individual trees of that species drop. Scientists agree that...
Partnerships between ant and plant species appear to arise from—but not drive—rapid diversification of ants into new species. Katrina Kaur of the University of Toronto, Canada, and colleagues present these findings in PLOS Computational Biology.
An international group of scientists led by the RIKEN Cluster for Pioneering Research has used observations from the Multi Unit Spectroscopic Explorer (MUSE) at the ESO Very Large Telescope (VLT) in Chile and the Suprime-Cam at the Subaru telescope to make detailed observations of the filaments of gas connecting galaxies in a large, distant proto-cluster in the early universe.
Travellers are willing to pay a little more for flights if they know the extra money will be used to address carbon emissions, a new study from the UBC Sauder School of Business has found.
NASA's InSight lander, which is on a mission to explore the deep interior of Mars, positioned its robotic arm this past weekend to assist the spacecraft's self-hammering heat probe. Known as "the mole," the probe has been unable to dig more than about 14 inches (35 centimeters) since it began burying itself into the ground on Feb. 28, 2019.
For the first time, researchers have observed at the molecular level how a protein associated with numerous health problems works.
Known to many as muscle wire or memory metal, shape memory alloys are materials that can be bent or deformed, and then return to their original shape when heat is applied. While people are most familiar with the material in "unbreakable" eye-glass frames, these alloys are also used as vibration dampers, actuators, and sensors in high technology applications like the aerospace and automotive...
Gender-inclusive spaces may help young people develop friendships across gender identities, according to a new study by a Washington State University researcher.
Interference in government research by US President Donald Trump's administration has reached a "crisis point" with almost weekly violations of previously respected safeguards, a report by a think tank said Thursday, warning that ignoring science has led to ineffective and costly policy.
We humans may consider a long-lived life to be anywhere from 60 to 100 years, depending on where we live. But what about chimpanzees, one of our closest living relatives?
A Dartmouth-led study examining carbon stocks in an actively managed mixed wood forest in New Hampshire finds that places with more trees have more carbon stored in both the trees and the soil. The findings, published in Forest Ecology and Management, demonstrate the connection between above ground and below ground carbon, which has implications for forest management strategies.
The skies were clear, the winds were low, and the lasers aligned. In April, instruments aboard NASA's Operation IceBridge airborne campaign and the Ice, Cloud and Land Elevation Satellite-2 succeeded in measuring the same Arctic sea ice at the same time, a tricky feat given the shifting sea ice. Scientists have now analyzed airborne and spaceborne height measurements, and found that the two...
NASA's Terra satellite passed over the eastern North Atlantic Ocean early on Oct. 3 and captured a visible image of Post-tropical Cyclone Lorenzo as it neared Ireland. Lorenzo's eastern side is already affecting Ireland, and both Ireland and the United Kingdom have posted warnings today.
Dark matter was likely the starting ingredient for brewing up the very first galaxies in the universe. Shortly after the Big Bang, particles of dark matter would have clumped together in gravitational "halos," pulling surrounding gas into their cores, which over time cooled and condensed into the first galaxies.
The new generation of successful female bloggers and influencers on social media are changing the identity of the stereotypical "ideal" housewife. This is according to a new study by Magdalena Petersson McIntyre, a researcher at the School of Business, Economics and Law at the University of Gothenburg.
