Generative AI applications use among us youth

JAMA Network Open

2026-02-02
(Press-News.org) About The Study: In this cross-sectional study, generative artificial intelligence (GenAI) app use varied widely among participants, with up to half of adolescents having some use and a small subset engaging in heavy use. Future research must address individual differences in GenAI use to determine impacts on development.

“I see a rubber duck” – neuroscientists use AI to discover babies categorize objects in the brain at just two months old

2026-02-02
Babies as young as two months old are able to categorise distinct objects in their brains – much earlier than previously thought – according to new research from neuroscientists in Trinity College Dublin.  The research, which combined brain imaging with artificial intelligence models, enriches our understanding of what babies are thinking and how they learn in the earliest months of life. The study has been just published in the journal Nature Neuroscience by a team from Trinity College Institute of Neuroscience (TCIN) and the ...

Two fundamental coordination patterns in underwater dolphin kick identified

2026-02-02
Tsukuba, Japan—The underwater dolphin kick is a swimming technique in which propulsion is generated solely through the undulatory motion of the lower limbs, increasing swimmers' speed by moving the body in a wavelike pattern similar to fish or marine mammals. However, because the human body is not naturally adapted to such undulatory movements, swimmers must master advanced motor skills to improve performance in this technique. This study analyzed time-series data of joint movements during underwater dolphin kick to examine differences in swimmer performance levels. Using conducting kinematic synergy analysis, the researchers identified two ...

Dynamic tuning of Bloch modes in anisotropic phonon polaritonic crystals

2026-02-02
Polaritons—hybrid light-matter particles—allow light to be squeezed into deep subwavelength scales, holding great promise for ultra-compact photonic devices. By structuring materials into periodic crystals, known as polaritonic crystals (PoCs), researchers can engineer exotic optical modes called Bloch modes for enhanced light control. However, once fabricated, these crystals and their Bloch modes are fixed, lacking the dynamic tunability required for adaptive optical devices. While graphene supports highly tunable plasmon polaritons, their performance is limited by substantial optical ...

In his new role, he directs the operations of the Institute’s technical divisions and administers SwRI’s internal research program in addition to other resources and programs. Thacker also joins the Institute’s executive team, which includes President and CEO Adam Hamilton, P.E., Vice President - Finance and CFO Beth Rafferty and ...

Korea University’s College of Medicine held the 2025 Joint Forum with Yale University

2026-02-02
On October 28th, Korea University’s College of Medicine (Dean Pyun Sung-Bom) and Yale University hosted a joint forum with the topic of 'Basic and Clinical Neuroscience' at lecture room 320, main building.   This joint forum was a part of the 120th anniversary celebration of Korea University. Following the last year’s theme of medical informatics, this year’s theme was neuroscience. The purpose of this forum was to realize the direction of joint research between the two universities and further enhancing their global cooperation system.   The ...

Wetlands do not need to be flooded to provide the greatest climate benefit

2026-02-02
Wetlands make up only about six percent of the land area but contain about 30 percent of the terrestrial organic carbon pool. Therefore, CO2 emissions from wetlands are central to the global climate balance. In Denmark, the plan is to flood 140,000 hectares of low-lying land such as bogs and meadows as part of the Green Tripartite Agreement. Flooding such areas will slow down the decomposition of organic material in the soil and keep the CO2 in the soil rather than allowing it to be released to the atmosphere and contribute to the greenhouse effect. At least, that has been the rationale until now. However, a new study from the University of Copenhagen, published in Nature ...

Bat virome evolution in Indochina Peninsula reveals cross-species origins of porcine epidemic diarrhea virus and regional surveillance gaps

2026-02-02
Bats, critical reservoirs of viruses with significant cross-species spillover risks, have long been understudied in the Indochina Peninsula. A study led by researchers from Beijing University of Chemical Technology, the Academy of Military Medical Sciences, and their partners has unveiled the region's bat virome diversity, offering key insights into the origins of porcine epidemic diarrhea virus (PEDV) and critical surveillance priorities. From 2020 to 2024, the team analyzed 659 samples from 197 bats across 16 species using next-generation sequencing (NGS). They identified 137 viral strains across 27 families, including 40 novel species. Rhinolophidae bats from ...

How a fridge could unlock modern dairy cattle breeding in the developing world

2026-02-02
A Hiroshima University-led project has secured a $1.8 million grant from the Gates Foundation to develop a way to store bull semen using simple refrigeration instead of costly liquid nitrogen, a shift that could remove a major barrier to modern dairy cattle breeding that has long excluded farmers in low-resource regions. If successful, the technology is expected to deliver far-reaching benefits on food security and livelihoods in local communities. The project, headed by Professor Masayuki Shimada of Hiroshima University’s Graduate School of Integrated Sciences for Life, received the grant in October 2025, marking the second time his laboratory has secured ...

Scientists unravel vines’ parasitic nature

2026-02-02
Twisting upwardly on trees and other plants—along with houses and even lampposts—vines are a wonder of nature. However, their marvels mask their parasitic behavior: in attaching to other life forms, vines block sunlight necessary for growth and strangle their hosts, preventing the flow of water and other nutrients. While these threats were widely known, less clear is what gives vines their searching, attaching, and climbing capabilities.  An international team of scientists has now unlocked a formula that enables vines to search for ...
