Theoretical perspective on C-H/O-H activation by Cu-O in biological and synthetic systems
Dioxygen activations constitute one of the core issues in copper-dependent metalloenzymes. Upon O2 activation, copper-dependent metalloenzymes, including particulate methane monooxygenases (pMMOs), lytic polysaccharide monooxygenases (LPMOs) and binu.....»»
ALICE probes the strong interaction three-body problem with new measurements of hadron–deuteron correlations
In an article recently published in Physical Review X, the ALICE collaboration presented its studies of correlations in the kaon–deuteron and proton–deuteron systems, opening the door to precise studies of the forces in three-body nuclear systems.....»»
Manganese cathodes could boost lithium-ion batteries
Rechargeable lithium-ion batteries are growing in adoption, used in devices like smartphones and laptops, electric vehicles, and energy storage systems. But supplies of nickel and cobalt commonly used in the cathodes of these batteries are limited......»»
Morphology study paves the way for spider fang-inspired cutting tools
When we think of spiders, the first thing that comes to mind is their ability to weave intricate and robust webs. But their ability to cut their own silk—the toughest natural material—and strong or tough synthetic fibers such as carbon or Kevlar,.....»»
New rules could help child welfare systems treat parents with disabilities more fairly
Parents with any kind of disability are much more likely to have some type of interaction with the child welfare system than other parents. This means they are more likely than other parents to be reported for child abuse and neglect and more likely.....»»
Fecal transplants reduce ADHD and anxiety symptoms in dogs with epilepsy, researchers find
Researchers from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) and Center for Systems Neuroscience in Hannover, Germany have discovered that fecal microbiota transplants (FMT) can reduce negative mental health symptoms i.....»»
New insights into hot carrier solar cells: Study explores hot electron tunneling and collection to enhance efficiency
Hot carrier solar cells, a concept introduced several decades ago, have long been seen as a potential breakthrough in solar energy technology. These cells could surpass the Shockley–Queisser efficiency limit, which is a theoretical maximum efficien.....»»
Tree frog tadpoles have a unique way of not contaminating their water supply: Not pooping
The Eiffinger's tree frog (Kurixalus eiffingeri), found on Ishigaki and Iriomote islands in Japan, has a unique biological adaptation: its tadpoles do not defecate during their early developmental stages. This finding by researchers at Nagoya Univers.....»»
Six initiatives for prioritizing undergraduate student well-being
In a perspective, Holly C. White and colleagues argue that student well-being should be a goal of pedagogy, along with traditional metrics such as GPA and student retention. Despite evidence linking certain academic experiences with well-being outcom.....»»
Scientists explore how indoor vertical farming could help future-proof food demand
To make sure everyone eats well in our crowded world, we need to innovate. Vertical farming systems, which grow plants intensively in an indoor setting, could be part of the answer—but to use them on a large scale we need to overcome key problems,.....»»
Navigating complex systems to preserve prairie wetlands
From grasslands to boreal forests, Saskatchewan has some of the most dynamic ecosystems in the country and is home to equally complex water systems. Researchers like Dr. Colin Whitfield (Ph.D.), associate professor in the School of Environment and Su.....»»
Potential indicators of life on other planets can be created in a lab
One way to understand the potential for life on far-off planets—those in other solar systems that orbit different stars—is to study a planet's atmosphere. Telescopic images often capture traces of gases that may indicate life and habitable planet.....»»
Human urine could be used as eco-friendly crop fertilizer: Study
Bacterial communities in soil are as resilient to human urine as synthetic fertilizers—making recycling the bodily fluid as a fertilizer for agricultural crops a viable proposition, according to a new study......»»
Florida company"s space balloon takes big step toward 1st human flight
The weekend trip was a success for Space Perspective, the company that already has more than 1,800 people waiting for their chance to take balloon rides in a posh capsule up to the edge of space......»»

Convergent evolution study sheds light on how new genes arise
Where do new genes come from? That's the question a team of biological sciences researchers from the U of A set out to answer in a new study......»»
Scientists seek a balance between crop production and protecting the environment
Scientists at the USDA's Agricultural Research Service (ARS), Northern Plains Agricultural Research Laboratory (NPARL), in Sidney, Montana, completed a study that shows the use of continuous cropping systems can better sustain crop yields while reduc.....»»
Tropical cyclone intensity exacerbated by increasing depth of ocean mixed layer, finds study
Tropical cyclones can have severe consequences for both the marine and terrestrial environments, as well as the organisms and communities who inhabit them. In the oceans, there can be alterations in sea surface temperature that disrupt biological pro.....»»
Were Bohr and von Neumann really in conflict over quantum measurements?
Analysis suggests that the two pioneers of quantum mechanics, Niels Bohr and John von Neumann, may have had more similar views than previously thought regarding the nature of quantum systems, and the classical apparatus used to measure them......»»
Partial automation technology encourages distraction, IIHS finds
Automated driving systems in a Volvo and Tesla increased complacency, even among experienced drivers......»»
Is AI exacerbating disparities in education?
While much has been made of artificial intelligence's promise to improve educational opportunities and outcomes, a group of Stanford students is highlighting the importance of a different perspective on AI in education: It isn't just about using AI t.....»»
