Science X / Deep inside a desert rock shelter, archaeologists uncovered an Ice Age mystery that refused to stay local for long
A remarkable discovery has been made in an Upper Paleolithic cave in the heart of Israel's rugged Negev Desert. Years after they were last worn, archaeologists dug up fragile seashell beads, still holding specks of ochre ...
Phys.org / Bacteria turn dissolved uranium into stable compound in 130 days, study finds
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), together with Wismut GmbH and scientists from the University of Granada in Spain, have demonstrated for the first time that bacteria can convert uranium dissolved ...
Medical Xpress / New study provides first evidence of dopamine system injury in the brain of long COVID patients
A new brain imaging study led by researchers at the Center for Addiction and Mental Health (CAMH), published in eBioMedicine, provides the strongest evidence to date that long COVID is associated with injury to dopamine-releasing ...
Medical Xpress / Brain glutamate changes could link cannabis use to a higher risk of psychosis
Cannabis, commonly known as marijuana, is a plant that contains psychoactive compounds that can temporarily alter people's brain activity and perceptions. While the consumption of this plant for medical or recreational purposes ...
Phys.org / Geoscientists reveal how Earth's forces are shaping the 'Roof of the World'
Geoscientists at the University of Glasgow have helped reveal new evidence about the formation of one of the highest mountainous areas on Earth—the Tibetan Plateau. A study by an international team of Chinese and U.K. geoscientists ...
Tech Xplore / Birdlike robot swims underwater, then flaps into flight without paddling
Loons, gulls, puffins and petrels are some of the 100 species of birds that can both fly and swim. These diving birds can plunge into water to swim after prey, and leap back into the air to fly away.
Phys.org / Physical laws explain why most flies evolved similar flight, with mosquitoes as outliers
A new study in PLOS Biology of 133 species of flies, mosquitoes and their relatives shows that most species fly in surprisingly similar ways. Physical and aerodynamic laws shape the evolution of their flight behavior more ...
Phys.org / Math reveals how honeybee hives balance the 'daring few, patient many' strategy
How do bees make group decisions without a leader? Math experts have determined that the best strategy is for a few to assume the risk of foraging under all conditions while the majority stay safely back and forage only when ...
Phys.org / Volcanoes and wildfires are adding water vapor to the stratosphere, raising climate concerns
Moderate volcanic eruptions and extreme wildfires since 2005 have led to an increase in the amount of water vapor in the stratosphere, a layer of Earth's atmosphere above the weather-filled troposphere. That's potentially ...
Phys.org / Researchers find simple solution for extending the lifespan of LEDs made from glowing quantum dots
A new study led by MIT researchers could drive the development of more energy-efficient digital displays—such as flat-screen TVs, augmented and virtual reality headsets, smartphone screens, medical imaging devices and even ...
Phys.org / Giant kangaroos survived until 6,500 years ago on the New Guinea coast
Roughly 50,000 years ago, a kangaroo unlike any alive today lived in the mountain rainforests of New Guinea.
Phys.org / Ancient DNA challenges family assumptions in medieval Scandinavian graves
When archaeologists find adults and children buried together in medieval graves, it is often assumed that they were members of the same family. A new study from Stockholm University in Science Advances suggests otherwise.
