Phys.org / How lifetime stress drives abnormal behaviors in lab monkeys
It is not unusual for laboratory monkeys to engage in abnormal repetitive behaviors (ARBs), such as pacing and hair-plucking. Conventional thinking is that these actions are linked to recent stresses or current housing conditions. ...
Phys.org / Recovery from sudden permafrost collapse ranges from 10 years to a century, study suggests
Some Arctic regions regain their "greenness" within a decade of a sudden permafrost collapse, while others can take a century or more to recover, researchers report in a new study. The difference is directly related to each ...
Phys.org / Chiral metasurfaces guide twisted light into free space
Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field rotates. The other comes from the shape of the wavefront itself, which can twist like a corkscrew ...
Medical Xpress / Radiation therapy improves outcomes for 'supermassive' bile duct tumors
A new study from researchers at The University of Texas MD Anderson Cancer Center demonstrates that a specialized high-dose type of radiation delivery may significantly improve outcomes for patients with large bile duct tumors ...
Medical Xpress / Global gun violence research requires a multidisciplinary approach, say experts
Gun violence remains a global public health crisis, with up to 71% of homicides worldwide involving firearms. Although gun culture and mass shootings are uniquely associated with the United States, firearm violence is a global ...
Phys.org / Impacts from meteors may have helped start life on Earth by creating hydrothermal vents
Meteor impacts may have helped spark life on Earth, creating hot, chemical-rich environments where the first living cells could take shape, according to research integrated by a recent Rutgers University graduate. Shea Cinquemani, ...
Phys.org / Forest soil on doormats rebalances urban homes' indoor microbiome, study suggests
Introducing forest soil on an entryway doormat shifted the indoor microbiome of Finnish homes closer to bacterial profiles found outdoors, with less contribution from human-associated bacteria, a new study shows. In the future, ...
Phys.org / Aquaculture is shifting toward less sustainable species, study says
While aquaculture has grown rapidly to meet global seafood demand, it is increasingly relying on species that are less beneficial for food security, climate mitigation, and biodiversity, said a new study from researchers ...
Phys.org / Cow manure digesters really do cut methane—unless they leak
A new study shows that systems designed to capture methane from cow manure, called dairy digesters, are highly effective. But on the rare occasions they fail, the leaks are large enough to offset their climate benefits.
Phys.org / Lab-based mini-atmosphere reveals how turbulence changes on different scales
With a new lab-based experiment, researchers in the UK and France have recreated the characteristic cascades of energy and angular momentum that underpin key features of Earth's atmosphere. Reporting in Physical Review Letters, ...
Phys.org / World's largest quantum circuit simulation for quantum chemistry achieved on 1,024 GPUs
A joint research team between the Center for Quantum Information and Quantum Biology (QIQB) at The University of Osaka and Fixstars Corporation has demonstrated one of the world's largest classical simulations of iterative ...
Tech Xplore / Chip-scale light technology could power faster AI and data center communications
Researchers at Trinity have developed a new light-based technology on a tiny chip that could help make the data centers behind cloud computing, artificial intelligence, and global internet services faster and more efficient. ...
