Phys.org / Sea reptile's tooth shows that mosasaurs could live in freshwater
Mosasaurs, giant marine reptiles that existed more than 66 million years ago, lived not only in the sea but also in rivers. This is shown by new research based on analyses of a mosasaur tooth found in North Dakota and believed ...
Phys.org / 'Self-activation' is part of the success strategy of parasitic weeds
Parasitic weeds extract water and nutrients from their host plants. But what makes these parasites so successful? A study led by Prof Susann Wicke from the Institute for Evolution and Biodiversity at the University of Münster ...
Phys.org / Storm study shows adaptive selection in southeast lizards
How do intermittent events like hurricanes impact natural selection? How do animals adapt to challenging weather? A University of Rhode Island professor has set out to track natural selection in the Anolis lizard over time ...
Phys.org / Swedish freshwater bacteria reveal lost genes and unexpected photosynthesis abilities
Bacteria are among the most diverse and ancient forms of life on Earth. Yet, much of what is known about them comes from a small group of species, mostly studied for their roles in human health.
Phys.org / Hidden patterns of isolation and segregation found in all American cities
A comprehensive analysis of 383 U.S. cities reveals a striking pattern: most have rings of isolation in suburban areas and segregated pockets near the urban core, that are shaped by race, wealth, and proximity to downtown, ...
Phys.org / Global measures consistently underestimate food insecurity: 1 in 5 who suffer from hunger may go uncounted
International humanitarian aid organizations rely on analyses from the Integrated Food Security Phase Classification (IPC) system, a global partnership that monitors and classifies the severity of food insecurity to help ...
Phys.org / The monster hiding in plain sight: JWST reveals cosmic shapeshifter in the early universe
In a glimpse of the early universe, astronomers have observed a galaxy as it appeared just 800 million years after the Big Bang—a cosmic Jekyll and Hyde that looks like any other galaxy when viewed in visible and even ultraviolet ...
Phys.org / Parker Solar Probe spies solar wind 'U-turn'
Images captured by NASA's Parker Solar Probe as the spacecraft made its record-breaking closest approach to the sun in December 2024 have now revealed new details about how solar magnetic fields responsible for space weather ...
Phys.org / Migratory birds' stunning precision in flight revealed by new data loggers
Red-backed shrikes fly thousands of kilometers to reach Africa—and they do so with astonishing precision. Aided by new technology, researchers at Lund University in Sweden have been able to track the birds' journeys in ...
Phys.org / Earth's atmosphere may help support human life on the moon
The moon's surface may be more than just a dusty, barren landscape. Over billions of years, tiny particles from Earth's atmosphere have landed in the lunar soil, creating a possible source of life-sustaining substances for ...
Phys.org / A new species of tiny orange frog discovered in Brazil's cloud forests
Despite the vast numbers of animal species already identified, the natural world is still capable of springing a few surprises. Deep in the cloud forests of the Serra do Quiriri mountain range in the southern Brazilian Atlantic ...
Phys.org / All-optical modulation in silicon achieved via an electron avalanche process
Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, communication and information ...
