Phys.org / Why meat-eating dinosaurs like T. rex evolved tiny arms
The evolution of tiny arms in several groups of meat-eating dinosaurs was likely driven by the development of strong, powerful heads, which were used to attack prey, according to a new study led by researchers at UCL (University ...
Phys.org / Romania dig uncovers 350-square-meter megastructure in 45-house prehistoric settlement
Researchers from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have found new indications of how large prehistoric settlements were organized. Their research focused on a special type of building known as a megastructure. ...
Phys.org / Chimpanzees reveal 69 socially learned behaviors, nearly doubling known cultural repertoire
Scientists have identified dozens of previously overlooked cultural behaviors in wild chimpanzees, suggesting that the great ape's culture extends far beyond complex skills like tool use. In a single community, they found ...
Phys.org / Neptune's mysterious moon Nereid may be original survivor of Triton's chaotic arrival
Neptune's far-flung moon Nereid may be the last of the planet's original companions that managed to survive a cosmic crash, scientists reported Wednesday.
Phys.org / Particle-by-particle tracking reveals uneven nanoparticle drug release
Precision medicine aims to transport therapeutic agents, such as molecules, proteins or RNA, to the exact place where they need to act within the body. One of the most promising strategies is the use of nanocarriers: nanoparticles ...
Phys.org / NASA's AWE instrument completes mission to study Earth's effect on space weather
On May 21, ground controllers powered down NASA's AWE (Atmospheric Waves Experiment) instrument, bringing the data collection phase of the mission to a successful and scheduled end, surpassing its planned two-year mission.
Medical Xpress / Why energy fades with age: Missing membrane lipid may destabilize mitochondria
Why do cells age—and why do we lose our energy and vitality as we get older? This question is one of the central challenges of modern biomedicine. The focus is particularly on mitochondria—tiny cellular organelles long known ...
Phys.org / Complexity isn't subjective—the right amount results in new material properties
Complexity may seem subjective, but a quantitative measure of the complexity of nanomaterials was recently developed by a team of researchers from the University of Michigan Engineering, the University of Southern California ...
Phys.org / Television news coverage of climate policy is limited and polarized in the US, study finds
Two-thirds of Americans want action on climate change, but people vastly underestimate public support for climate solutions and policy. Historically, U.S. news outlets overrepresented views on climate change that went against ...
Science X / A 6,000-year-old necropolis in central Spain is forcing a radical rethink of who built Europe's first great tombs
Archaeologists working in Toledo, central Spain, have discovered what they believe is the oldest documented monumental necropolis in the interior of the Iberian Peninsula. This ancient site dates back to about the end of ...
Dialog / A new light-based sensor could help make ultrasensitive disease testing more portable
When we think about highly sensitive medical testing, we often imagine a hospital laboratory filled with large instruments, trained technicians, and carefully controlled conditions. This is especially true for optical biosensing, ...
Phys.org / What if the direction of a magnet could shape the building blocks of life?
In a new discovery, researchers from the Hebrew University of Jerusalem and the Weizmann Institute of Science have found that something in the direction of a magnetic field can influence how molecules of life behave at the ...
