Summer forage capabilities of tepary bean and guar in the southern great plains
Nearly two dozen states and several cities on Wednesday filed a legal challenge to the Trump administration's rollback of Obama-era mileage standards, saying science backed up the old regulations developed with the help of the nation's car makers.
Perennial warm-season grasses do not provide high-quality forage during mid to late-summer, which limits yearling stocker cattle from maintaining high rates of growth in the Southern Great Plains. This shortage has resulted in a continual search by researchers for annual legumes that can provide sufficient amounts of nutritious forage during August through September.

What's the secret behind the world's stickiest brands?
Historic SpaceX launch postponed because of stormy weather
Researchers from Newcastle University London, Fordham University, and University of Minho published a new paper in the Journal of Marketing that examines how some brands create "sticky" customer journeys that keep customers addicted.
Caveolin binding motif in Na/K-ATPase is required for stem cell differentiation, organogenesis in animals
The launch of a SpaceX rocket ship with two NASA astronauts on a history-making flight into orbit was called off with 16 minutes to go in the countdown Wednesday because of thunderclouds and the danger of lightning.
These tiny, self-assembling traps capture PFAS
New findings reveal the importance of the Na/K-ATPase protein in stem cell differentiation and organogenesis, in a study led by scientists at Marshall University that involves the scaffolding function of the Na/K-ATPase.
Scientists warn of 'zombie fires' in the Arctic
University at Buffalo chemists have shown that self-assembling molecular traps can be used to capture PFAS—dangerous pollutants that have contaminated drinking water supplies around the world.
2 U.S. astronauts board SpaceX rocket for historic launch
Dormant "zombie fires" scattered across the Arctic region—remnants of record blazes last year—may be coming to life after an unusually warm and dry Spring, scientists warned Wednesday.
A potential explanation for urban smog: Aerosol particle growth higher in cold climates
With thunderstorms threatening a delay, two NASA astronauts climbed aboard a SpaceX rocket ship Wednesday for liftoff on a history-making flight that was seen as a giant leap forward for the booming business of commercial space travel.
Artificial intelligence reveals mechanism for kin selection in a wild primate
The effect of nitric acid on aerosol particles in the atmosphere may offer an explanation for the smog seen engulfing cities on frosty days. Under laboratory conditions, researchers at CERN in Switzerland observed the formation of atmospheric aerosols and discovered new information on the link between nitrogen oxides originating in traffic and the energy industry, and the climate and air quality....
Initial Upper Paleolithic technology reached North China by around 41,000 years ago
More like mom or dad? Human babies always get this curious look on their face combined with the question whom the child resembles most. The answers vary depending on the degree of kinship, gender and the time of assessment. Mandrills, monkeys living in Equatorial Africa, may recognize facial features coding relatedness better than humans. Scientists at the German Primate Center—Leibniz Institute...
Exploring the use of 'stretchable' words in social media
A wave of new technology in the Late Paleolithic had reached North China by around 41,000 years ago, according to a study published May 27, 2020 in the open-access journal PLOS ONE by Fei Peng of the Minzu University of China, Beijing and colleagues.
In stressed ecosystems Jurassic dinosaurs turned to scavenging, maybe even cannibalism
An investigation of Twitter messages reveals new insights and tools for studying how people use stretched words, such as "duuuuude," "heyyyyy," or "noooooooo." Tyler Gray and colleagues at the University of Vermont in Burlington present these findings in the open-access journal PLOS ONE on May 27, 2020.
New clues to deep earthquake mystery
Among dinosaurs of ancient Colorado, scavenging and possibly cannibalism were responses to a resource-scarce environment, according to a study published May 27, 2020 in the open-access journal PLOS ONE by Stephanie Drumheller of the University of Tennessee, Knoxville, and colleagues.
Study shows erosion of ozone layer responsible for mass extinction event
A new understanding of our planet's deepest earthquakes could help unravel one of the most mysterious geophysical processes on Earth.
SpaceX crewed flight is 'go for launch': NASA chief
Researchers at the University of Southampton have shown that an extinction event 360 million years ago, that killed much of the Earth's plant and freshwater aquatic life, was caused by a brief breakdown of the ozone layer that shields the Earth from damaging ultraviolet (UV) radiation. This is a newly discovered extinction mechanism with profound implications for our warming world today.
Bob and Doug, the best friends on historic SpaceX-NASA mission
SpaceX's historic first crewed launch was set to proceed as scheduled Wednesday, NASA announced at midday, but some uncertainty remained over weather conditions just over four hours before takeoff.
Researchers use whole living cells as 'templates' to seek for bioactive molecules
Robert Behnken and Douglas Hurley, the astronauts set to launch into orbit on a SpaceX rocket Wednesday, are both former military pilots, both recruited by NASA in 2000, and both married to fellow astronauts.
Public parks guaranteeing sustainable well-being
A study performed by researchers at the Institute for Advanced Chemistry of Catalonia (IQAC) from the Spanish National Research Council (CSIC) pioneers the use of whole living cells (human lung adenocarcinoma) in dynamic combinatorial chemistry systems. This research, published in the journal Angewandte Chemie International Edition, proposes a new methodology to discover new bioactive molecules in...
Rijksmuseum given unique painting to remember virus victims
An international team led by the University of Geneva (UNIGE) has ascertained how green spaces contribute to the well-being of city-dwellers. The research shows that parks play an essential role in the well-being of individuals, regardless of their social class, and that they cannot be replaced by other venues where people meet, such as shopping centers. When these parks are closed—as during the...
SpaceX on cusp of launching astronauts, back on home turf
Amsterdam's Rijksmuseum will display a famous 16th-century painting donated to commemorate victims of the coronavirus when it re-opens next week, almost three months after closing its doors, the museum said Wednesday.
NASA chief "all in" for Tom Cruise to film on space station
With bad weather threatening a delay, two NASA astronauts suited up for the launch of a SpaceX rocket ship Wednesday on a history-making flight to the International Space Station that was seen as a giant leap forward for the booming business of commercial space travel.
Cyclones can damage even distant reefs
NASA is rolling out the International Space Station's red carpet for Tom Cruise to make a movie in orbit.
Researchers take a cue from nature to create bulletproof coatings
Big and strong cyclones can harm coral reefs as far as 1000 kilometres away from their paths, new research shows.
Airborne science discovers complex geomorphic controls on Bornean forests
Shrimp, lobsters and mushrooms may not seem like great tools for the battlefield, but three engineers from the University of Houston are using chitin—a derivative of glucose found in the cellular walls of arthropods and fungi—and 3-D printing techniques to produce high-impact multilayered coatings that can protect soldiers against bullets, lasers, toxic gas and other dangers.
Tropical forests contain some of the most biodiverse and dynamic ecosystems in the world. Environmental conditions such as precipitation, temperature, and soils shape the biota of the landscape. This influence is especially noticeable when comparing the towering trees found in low elevation forests to the hardier, shorter ones found at the top of tropical mountains. Together, these factors create...
