Earliest evidence of Ephedra use found in 15,000-year-old Moroccan burial
An international group of researchers led by the University of Las Palmas de Gran Canaria have uncovered the earliest evidence of Ephedra use from the charred remains of the plant in a 15,000-year-old human burial site in northeastern Morocco......»»
Australian dragon study reveals surprising link between motor systems control and sleep rhythms
Sleep is one of the most mysterious, yet ubiquitous components of our biology. It has been described in all major groups of animals, including worms, jellyfish, insects or cephalopods, and in all vertebrates, from fish to humans. Common characteristi.....»»
Gray squirrel control: Study shows promise for effective contraceptive delivery system
A study published in the journal Pest Management Science sheds light on the behavior of gray squirrels (Sciurus carolinensis) and explores methods for the targeted delivery of oral contraceptives to control their populations......»»
Coyotes are thriving despite human and predator pressures, large-scale study finds
Research led by the University of New Hampshire sheds light on how coyotes, North America's most successful predators, are responding to various environmental pressures, including human development, hunting and competition with larger carnivores. Sur.....»»
Climate change is contributing to drought in the American West even without rainfall deficits, scientists find
Higher temperatures caused by anthropogenic climate change made an ordinary drought into an exceptional drought that parched the American West from 2020–2022. A study by UCLA and National Oceanic and Atmospheric Administration climate scientists ha.....»»
Pathogens that cling to microplastics may survive wastewater treatment
Wastewater treatment fails to kill several human pathogens when they hide out on microplastics in the water, reports a study led by Ingun Lund Witsø of the Norwegian University of Life Sciences, published November 6, 2024 in the open-access journal.....»»
Grocery stores are more reliable than sushi restaurants in labeling salmon properly, Seattle study finds
In a study of salmon samples from Seattle, Washington, grocery stores and sushi restaurants, DNA analysis revealed that 18% were mislabeled. Tracie Delgado and colleagues at Seattle Pacific University, WA, U.S., present these findings in the open-acc.....»»
Soundtracks in toy ads shape gender stereotypes, study suggests
A study from Queen Mary University of London reveals that the music and soundscapes used in toy commercials are reinforcing rigid gender norms, shaping the way children perceive masculinity and femininity. The research uncovers how gender stereotypes.....»»
New PFAS testing method could make water testing more affordable, portable and accessible
University of Massachusetts Amherst researchers have discovered a new way to detect per- and polyfluoroalkyl substances (PFAS) in water. This marks an important step forward in creating testing devices that are simpler, more cost-effective, faster an.....»»
"Shallow" sports and "deep" social hierarchies: Not all pecking orders are created equally
University of Michigan researchers have added a new dimension to the mathematics used to predict the outcomes of all manner of competitions, including sports, games and social hierarchies in both humans and animals......»»
The high cost of complexity: New study explores energy needs of multicellular life
Between 1.8 billion and 800 million years ago, earthly life was in the doldrums. During this period, called the "boring billion," the complexity of life remained minimal, dominated by single-celled organisms with only sporadic ventures into multicell.....»»
More families purchased school meals after federal nutrition policies enacted, research suggests
Families purchased more school lunches and breakfasts the year after the federal government toughened nutritional standards for school meals. A new University of California, Davis, study suggests that families turned to school lunches after the Obama.....»»
Public pressure found to influence whether companies reduce their environmental impact
The effectiveness of national voluntary programs asking companies to pledge to lower their pollution and greenhouse gas emissions depends on pressure from the public, according to a new study led by a Penn State researcher......»»
Hard in theory, easy in practice: Why graph isomorphism algorithms seem to be so effective
Graphs are everywhere. In discrete mathematics, they are structures that show the connections between points, much like a public transportation network. Mathematicians have long sought to develop algorithms that can compare any two graphs......»»
Vampire bats" metabolism mirrors that of blood-sucking insects, biologists find
A pair of biologists at the University of Toronto has found that vampire bats are able to burn amino acids as a fuel source similarly to blood-sucking insects. In their study published in the journal Biology Letters, Giulia Rossi and Kenneth Welch co.....»»
Novel nanoparticles can trap and neutralize large amounts of SARS-CoV-2
Researchers from the IBB-UAB have developed a new class of nanostructures capable of trapping and neutralizing large quantities of the SARS-CoV-2 virus particles, both in liquid solutions and on the surface of materials......»»
Scientists use high-energy heavy ion collisions as a new tool to reveal subtleties of nuclear structure
Scientists have demonstrated a new way to use high-energy particle smashups at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy (DOE) Office of Science user facility for nuclear physics research at DOE's Brookhaven National La.....»»
AI-driven mobile robots team up to tackle chemical synthesis
Researchers at the University of Liverpool have developed AI-driven mobile robots that can carry out chemical synthesis research with extraordinary efficiency......»»
Genetic repair via CRISPR can inadvertently introduce other defects, researchers show
The CRISPR molecular scissors have the potential to revolutionize the treatment of genetic diseases. This is because they can be used to correct specific defective sections of the genome. Unfortunately, however, there is a catch: under certain condit.....»»
