Researchers discover gene variants in wheat and barley that improve nitrogen utilization
Nitrogen as a fertilizer can increase yields. However, too much nitrogen can also have negative effects, such as groundwater pollution, high energy consumption in fertilizer production and the generation of climate-relevant gases. Science is therefore looking for ways to help crops thrive with less nitrogen.
Foal bred by surrogacy highlights lab's expertise
Ellie is an 11-year-old chestnut mare with a fetching white stripe on her face, and she's about as loved as any horse could be.
New report recommends solutions to reduce crop loss in Tanzania
Research from the Institute for Sustainable Food at the University of Sheffield has investigated the reasons for post-harvest loss of crops produced in the Morogoro region of Tanzania.
The untold history of the horse in the American Plains: A new future for the world
The continent of North America is where horses first emerged. Millions of years of evolutionary changes transformed the horse before it became the natural companion of many Indigenous Peoples and the flagship symbol of the Southwest. An international team uniting 87 scientists across 66 institutions around the world now begins to refine the history of the American horse. This work, which embeds...
Predatory dinosaurs such as T. rex sported lizard-like lips, suggests study
A new study suggests that predatory dinosaurs, such as Tyrannosaurus rex, did not have permanently exposed teeth as depicted in films such as Jurassic Park, but instead had scaly, lizard-like lips covering and sealing their mouths.
Moiré superlattices show superpower in photonics and optoelectronics
Researchers from the Institute of Physics (IOP) of the Chinese Academy of Sciences, collaborating with international colleagues, have presented an overview of recent progress in emerging moiré photonics and optoelectronics. It was published in Science on March 30.
AI predicts enzyme function better than leading tools
A new artificial intelligence tool can predict the functions of enzymes based on their amino acid sequences, even when the enzymes are unstudied or poorly understood. The researchers said the AI tool, dubbed CLEAN, outperforms the leading state-of-the-art tools in accuracy, reliability and sensitivity. Better understanding of enzymes and their functions would be a boon for research in genomics,...
Newly discovered trigger for major depression opens new possibilities for treatments
A common amino acid, glycine, can deliver a "slow-down" signal to the brain, likely contributing to major depression, anxiety and other mood disorders in some people, scientists at the Wertheim UF Scripps Institute for Biomedical Innovation & Technology have found.
News at a glance: A particle’s weighty measurement, Marburg in Africa, and a fossil called “the blob”
PARTICLE PHYSICS
Particle mass dispels hint of new physics
A fleeting, weighty elementary particle called the W boson has just the mass predicted by theory, physicists working with Europe’s Large Hadron Collider (LHC) reported this week at a conference in Italy. The finding comes from ATLAS, one of four large particle detectors fed by the LHC,...
Tyrannosaurus rex had lips over its teeth, research suggests
Contrary to depiction in movies like Jurassic Park, scientists now believe T rexes were not ‘toothy lipless things’While T rex is often depicted prowling the landscape while sporting a toothy grin, its fearsome teeth may actually have been concealed behind a pair of thin, scaly lips, research suggests.Experts say the perception that theropods were lipless arose because of the huge size of...
Hubble finds Saturn's rings heating its atmosphere
The secret has been hiding in plain view for 40 years. But it took the insight of a veteran astronomer to pull it all together within a year, using observations of Saturn from NASA's Hubble Space Telescope and retired Cassini probe, in addition to the Voyager 1 and 2 spacecraft and the retired International Ultraviolet Explorer mission.
Interviews with icons yield lessons on productivity in 'Wisdom Years'
The Wonder Years can be great, sure: first loves, long summers, panoramic dreams exclusive to those with a lifetime of runway. The Working Years, too: established identity, new family and old friends, freedom to pursue personal goals and professional satisfaction.
How to Harness Mega Seaweed Blobs For a More Sustainable Future
On Oct. 7, 1492, Christopher Columbus, aboard his ship the Santa María, had been at a complete standstill for 21 days, trapped in a very strange sea which he would later name the Sargasso Sea—sargazo in Spanish meaning “gulfweed.” Today, the Sargasso Sea—an elliptical expanse in the southwestern Atlantic at the center of which lies Bermuda—is six times the...
Asian swamp eels spread in the Everglades: 'Potentially the worst species we've had yet'
For a crayfish in the Florida Everglades, its worst nightmare is three feet long, dark brown and pure muscle, with a mouth like a vacuum that sucks up nearly everything it can find—tiny fish, small shellfish, turtle eggs and frogs.

Saving the salamanders: Spring road closures help these critters migrate
In this week's issue of our environment newsletter, we look at the steps taken every spring in Canada to protect migrating salamanders and what this week's federal budget promised on greening the electricity...
Filipinas stare through the glass ceiling in STEM fields
The Philippines is celebrating March as women's month while citing its achievements in gender equality from increased female educational attainment to political empowerment.
Scientists analyze sounds emitted by plants

Researchers have recorded and analyzed sounds distinctly emitted by plants. The click-like sounds, similar to the popping of popcorn, are emitted at a volume similar to human speech, but at high frequencies, beyond the hearing range of the human ear.
Lawsuit jeopardizes use of crucial wildfire retardant, US Forest Service claims
For most Californians, the sight of aircraft spewing neon pink liquid over flaming trees and brush has become a hallmark of aggressive wildfire suppression campaigns—if not a potent symbol of government's struggle to control increasingly destructive forest fires.
Ancient forests, seaways, and climate: Lessons from Miocene for today's world
Widespread forests once played a significant role in warming the climate during the Middle Miocene Climate Optimum (MMCO), while open Panama and Tethys Seaways served as "shortcuts" for the Atlantic Meridional Overturning Circulation (AMOC).
Changes in dominance of plant species with high stoichiometric plasticity exacerbate nitrogen–phosphorus imbalance
In terrestrial ecosystems, nitrogen (N) and phosphorus (P) are major nutrients limiting the increase in primary productivity. The imbalance of N and P input may result in a series of ecological results.
