An eagle twice the size of the modern-day apex predator the wedge-tailed eagle, which soared over southern Australia more than 60,000 years ago, had a wingspan up to 3m wide and powerful talons wide enough to grab a small kangaroo or koala.
Sleeping less than five hours a night is associated with a 74% raised likelihood of developing peripheral artery disease (PAD) compared with seven to eight hours.
About 2,000 young, seemingly healthy people under the age of 25 die annually of sudden cardiac arrest. Rutgers emergency medicine experts highlight the importance of CPR as a lifesaving procedure for children’s activities
An international scientific team led by Stony Brook University paleontologist Andrew J. Moore, PhD, has revealed that a Late Jurassic Chinese sauropod known as Mamenchisaurus sinocanadorum sported a 15-meter-long neck. The details will be published in the Journal of Systematic Palaeontology and provide fresh insights on the evolution of the iconic sauropod body.
Bald Eagles and dairy farmers exist in a mutually beneficial relationship in parts of northwestern Washington State. According to a new study, this "win-win" relationship has been a more recent development, driven by the impact of climate change on eagles' traditional winter diet of salmon carcasses, as well as by increased eagle abundance following decades of conservation efforts.
Up to 50 percent of cancer-signaling proteins once believed to be immune to drug treatments due to a lack of targetable protein regions may actually be treatable, according to a new study from the Perelman School of Medicine at the University of Pennsylvania. The findings, published this month in Nature Communications, suggest there may be new opportunities to treat cancer with new or existing drugs.
In reviewing data from previous studies, a team lead by researchers at the University of Chicago and the French National Institute of Health and Medical Research (Inserm) found that individuals who had fewer than six hours of sleep per night in the days surrounding vaccination had a blunted antibody response. That indicates efforts to promote heathy sleep duration ahead of an immunization could be an easy way to improve vaccine effectiveness.

He is the Baylor Scott & White Health’s sixth and newest facility dog, provided through a unique collaboration with not-for-profit Canine Companions®.
In the Pacific Northwest and British Columbia, southern resident orcas have experienced no net population growth since the 1970s. But northern resident orcas, with a similar diet and territory, have grown steadily. A new study may help explain why: The two populations differ in how they hunt for salmon, their primary and preferred food source.
Both conservative and liberal Americans share fake news because they don’t want to be ostracized from their social circles, according to research published by the American Psychological Association.
Doublet Pool’s regular thumping is more than just an interesting tourist attraction. A new study led by University of Utah researchers shows that the interval between episodes of thumping reflects the amount of energy heating the pool at the bottom, as well as in indication of how much heat is being lost through the surface. Doublet Pool, the authors found, is Yellowstone’s thumping thermometer.
A shot of a liver-produced hormone called FGF21 sobered up mice that had passed out from alcohol, allowing them to regain consciousness and coordination much faster than those that didn’t receive this treatment, UT Southwestern researchers report in a new study. The findings, published in Cell Metabolism, could lead to effective treatments for acute alcohol intoxication, which is responsible for about 1 million emergency room visits in the U.S. each year.
New methodology and tools his team developed by phage expert Graham Hatful provides the opportunity to watch in unprecedented detail as a phage attacks a bacterium.
Though wildlife trafficking has been effectively disrupted since the first World Wildlife Day—established 50 years ago today via the 1973 Convention on International Trade in Endangered Species (CITES) of Wild Fauna and Flora—a newly published case study on one of the world’s rarest tortoise species, the ploughshare tortoise, highlights how much room for improvement still exists.
Cedars-Sinai investigators have produced the most extensive analysis to date of changes in the retina—a layer of tissue at the back of the eye where visual information originates—and how those retinal changes correspond to brain and cognitive changes in Alzheimer’s disease patients.
Questions remain about artificial tears linked to an outbreak of Pseudomonas aeruginosa infections involving 64 people in 13 states, including 8 cases of vision loss, as well as lung and urinary tract infections, and one death. Federal agencies warned people to stop using EzriCare and Delsam Pharma artificial tears after tests of opened bottles used by those affected found a rare, extensively drug-resistant strain of P. aeruginosa. The strain had never been reported in the United States.What is clear is that eye health experts have advice for people using artificial tears, which are sold over the counter and widely used for eye irritation associated with dry eye disease, contact lens use, and refractive surgery, as well among those using other eye drops regularly, such as for glaucoma.
A first-person account by the parent of a patient receiving eating disorders treatment at Michigan Medicine; the author's name is withheld to protect privacy. The piece quotes a psychiatrist with the program, who reviewed the piece before publication.
In a new study, researchers used new technologies to remotely document, for the first time in the wild, the location and timing of shark birth. Named the Birth-Alert-Tag (BAT), this new satellite tag remained inside the uterus, along with the developing shark pups, until the mother shark gave birth and expelled the newborn pups, along with the BAT, into the surrounding water. The BAT then floated to the surface and transmitted to satellites the location of where the shark birth took place. The first of its kind, the BATs were successfully deployed in a tiger shark and scalloped hammerhead shark, documenting the location birth.
The time has come to create a new kind of computer, say researchers from John Hopkins University together with Dr Brett Kagan, chief scientist at Cortical Labs in Melbourne, who recently led development of the DishBrain project, in which human cells in a petri dish learnt to play Pong.
A liquid nitrogen spray developed by Washington State University researchers can remove almost all of the simulated moon dust from a space suit, potentially solving what is a significant challenge for future moon-landing astronauts.
University of South Australia researchers are calling for exercise to be a mainstay approach for managing depression as a new study shows that physical activity is 1.5 times more effective than counselling or the leading medications.
A new type of catalyst breaks down polyolefin plastics into new, useful products. This project is part of a new strategy to reduce the amount of plastic waste and its impact on our environment, as well as recover value that is lost when plastics are thrown away. The catalyst was developed by a team from the Institute for Cooperative Upcycling of Plastic (iCOUP), a U.S. Department of Energy, Energy Frontier Research Center.
56 million years ago, the Earth experienced one of the largest and most rapid climate warming events in its history: the Paleocene-Eocene Thermal Maximum (PETM), which has similarities to current and future warming.
In a new study published February 16, 2023, in Nature Genetics, researchers from the University of Chicago characterized the impact of a genetic variant associated with higher cholesterol and triglyceride blood levels in women, suggesting that similar genes might lead to different patterns of fat distribution and obesity-related disease risk for women.
Groups of spiders could be used as an environmentally-friendly way to protect crops against agricultural pests. That's according to new research, led by the University of Portsmouth, which suggests that web-building groups of spiders can eat a devastating pest moth of commercially important crops like tomato and potato worldwide.
A review article published today in Nature addresses this conflict between models and evidence, known as the Holocene global temperature conundrum. Lead author Darrell Kaufman, a Regents’ professor in the School of Earth and Sustainability, and University of Arizona postdoctoral researcher Ellie Broadman, a co-author who worked on this study while earning her Ph.D. at NAU, analyzed a broad swath of available data from the last 12,000 years to break down the conundrum.
Coffee drinkers can take advantage of a new placebo discovery showing decaffeinated coffee quenches withdrawal symptoms in people reliant on their daily caffeine fix.
Contrary to some common claims, a study led by Johns Hopkins Medicine researchers found that relatively high doses of cannabidiol (CBD) may increase the adverse effects of delta-9-tetrahydrocannabinol (THC), the main active ingredient in cannabis that can cause a mood alteration or a “high” sensation. The findings show that in edible cannabis products, CBD inhibits the metabolism, or breakdown, of THC, which may result in stronger and longer drug effects.
Thanks to researchers at NSU’s Guy Harvey Research Institute (GHRI) who designed a novel electronic tag package incorporating high-tech sensors and a video camera, we now have for the first time, a detailed view of exactly how sailfish behave and hunt once they are on their own and out of view of the surface.
Descriptions and phrases used in the Revelation of John are similar in terminology to those appearing on curse tablets produced in antiquity and the associated sorcery rituals.
Dust launched from the moon’s surface or from a space station positioned between Earth and the sun could reduce enough solar radiation to mitigate the impacts of climate change.
Patients’ satisfaction with their physicians may influence their decisions to undergo bariatric surgery, according to a multicenter study involving UT Southwestern and the UTHealth School of Public Health published in JAMA Network Open.
New research from Washington University in St. Louis suggests that the day-long implicit bias-oriented training programs now common in most U.S. police departments are unlikely to reduce racial inequity in policing.
Play is often considered an indicator and promotor of animal welfare. Playing with your cat may also nurture closer cat-human bonds. In a new study, scientists have investigated these links by applying in-depth empirical methods to analyse data gathered from around the world.
Some past research has suggested that falsehoods travel more quickly online than the truth and are more popular with the public, but a new study gives a more hopeful view.
Scientists discovered the first-ever Dickinsonia fossil in India two years ago, changing our understanding of how the continent came to be. Now, new research shows the "fossil" was just a beehive all along, changing our understanding for a second time, and the original scientists now support the new findings.
Iowa State researchers have developed and repeatedly tested a procedure that captures more information from eyewitnesses and improves the accuracy of lineups in police investigations.
Data stored in ice cores dating back 55 years bring new insight into atmospheric levels of a molecule that can significantly affect weather and climate.
