Signature of spin-triplet exciton condensations in LaCoO3 at ultrahigh magnetic fields up to 600 T

Scientists at the University of Electro-Communications successfully measured the effects of an ultra-high magnetic field on a transition metal oxide, discovering signs of a new magnetic superfluid state. This achievement has significant implications for spintronics technology and potential applications in quantum computing.

Can a city store as much carbon as a forest?

A new metric, called the carbon storage (CS) factor, enables urban planners to evaluate how a new development will affect the city's carbon balance. By using the right kind of wooden construction technologies, up to 70% of future construction can preserve lost forest carbon storage capacity.

Hey Siri, can you hear me? #ASA184

Researchers found that people produce louder and slower speech with less pitch variation when communicating with AI systems, while clearer speech improves comprehension. The study aims to improve AI's ability to understand human speech and investigate language changes as technology advances.

Environment impacts mental health of young people - research

Research found that young people living in health-constraining environments were more likely to experience poorer emotional and mental health. In contrast, those living in health-promoting environments were less likely to have problems with substance-abuse and hospitalisations for self-harm.

Regulations reducing lead and copper contamination in drinking water generate $9 billion of health benefits per year according to new analysis

A new study from Harvard T.H. Chan School of Public Health estimates that regulations reducing lead and copper contamination in drinking water generate $9.2 billion in health benefits annually, exceeding the EPA's public estimates by an order of magnitude. The analysis also reveals at least $2 billion in infrastructure benefits, bringi...

Tooth enamel provides clues to hunter-gatherer lifestyle of Neanderthals

A study using tooth enamel analyzed by laser ablation revealed that Neanderthals in western Europe hunted large animals, such as wild goat and horses, whereas humans consumed smaller creatures like rabbits and fish. The researchers estimated the territory size of both human groups, finding contrasting results.

The Voting Rights Act’s impact on Black representation in local government

The Voting Rights Act of 1965 significantly increased Black representation in local government, particularly in county commissions where coverage was implemented. The study found that capital spending grew more rapidly in these counties with higher shares of African Americans, indicating a positive impact on local governance. However, ...

Fentanyl, heroin use substantially decline in patients receiving methadone treatment for opioid use disorder during first year

Patients receiving methadone treatment for opioid use disorder show significant decline in fentanyl and heroin use over the course of a year, with average positivity rates dropping from 21.8% to 17.1% for fentanyl and 8.4% to 4.3% for heroin. Methamphetamine and cocaine use remains steady.

The impact of thermal drawdown-induced alterations in rock thermal properties on heat recovery

A team of researchers from Peking University found that temperature-dependent rock thermal conductivity and specific heat capacity affect the long-term thermal performance of Enhanced Geothermal Systems (EGS). The study showed that increased thermal conductivity improves thermal conduction, while decreased specific heat capacity impair...

New research sheds light on how human vision perceives scale

Researchers from Aston University and the University of York discovered new insights into how the human brain makes perceptual judgments of the external world. They found that humans can exploit 'defocus blur' to infer perceptual scale, but this process is crude and more heuristic than metrical analysis.
