Phys.org / Baby dinosaurs were common prey for Late Jurassic predators, reconstructed food web suggests
Babies and very young sauropods—the long-necked, long-tailed plant-eaters that in adulthood were the largest animals to have ever walked on land—were a key food sustaining predators in the Late Jurassic, according to ...
Phys.org / Land-intensive carbon removal requires better siting to protect biodiversity, study warns
New research looks at carbon dioxide removal—where carbon is absorbed from the atmosphere and stored—and finds that large-scale reliance on land-based methods, such as planting forests or bioenergy with carbon capture ...
Phys.org / Scientists marvel at a Galapagos seabird that wandered 3,000 miles to California
Scientists on a research vessel off the central California coast spotted a waved albatross, marking just the second recorded sighting of the bird north of Central America.
Phys.org / Gravitational wave signal tests Einstein's theory of general relativity
For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers an opportunity to test ...
Phys.org / A new method to search for ultralight dark matter with advanced optical cavities
Dark matter is a mysterious type of matter that does not emit, absorb, or reflect light, yet is predicted to account for most of the universe's mass. While physicists have gathered extensive indirect evidence of its existence, ...
Phys.org / 2D discrete time crystals realized on a quantum computer for the first time
Physical systems become inherently more complicated and difficult to produce in a lab as the number of dimensions they exist in increases—even more so in quantum systems. While discrete time crystals (DTCs) had been previously ...
Phys.org / The first headbutting paravian: Bird-like dinosaur likely used thick skull to win over mates
Whether it's digging up weathered bones from a paleontological site or reexamining forgotten trays in museum and university collections, the study of dinosaurs still throws up something new.
Phys.org / AI enables a who's who of brown bears in Alaska
A team of scientists from EPFL and Alaska Pacific University has developed an AI program that can recognize individual bears in the wild, despite the substantial changes that occur in their appearance over the summer season. ...
Phys.org / Growing meltwater reservoirs—glacial lakes are both a resource and a habitat worthy of protection
Should growing glacial lakes be used for energy production and water supply—or remain protected as ecologically valuable systems? A research team from the University of Potsdam, together with partners from the University ...
Phys.org / Measuring the quantum extent of a single molecule confined to a nanodroplet
There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is still enormously useful as its (complex) square represents the probability density of the system ...
Phys.org / New satellite method maps 'creeping drought' in Canada's mountain snow
Researchers at Concordia have developed a new method of measuring the amount of usable water stored in snowpacks. The comprehensive technique, known as snow water availability (SWA), uses satellite data and climate reanalysis ...
Phys.org / Gaia data reveal three galactic open clusters in detail
Using ESA's Gaia satellite, astronomers have investigated three open clusters in the galactic disk, namely Berkeley 17, 18 and 39. Results of the new study, published January 21 on the arXiv pre-print server, yield crucial ...
