Gemini data critical to revealing that Hayabusa2 target is tinier and faster than thought

Astronomers using the Gemini South telescope have found that asteroid 1998 KY26 is much smaller and spinning faster than previously thought. The asteroid is approximately 11 meters wide and completes a rotation in just five minutes, making it challenging for Hayabusa2 to land on its surface.

Timely pain treatment linked to reduced hospitalizations for children with sickle cell disease

A new study finds that prompt administration of opioid pain relief in emergency departments can reduce hospitalization rates for children with sickle cell disease. Children who received timely first-dose administration within 60 minutes and second-dose administration within 30 minutes showed reduced hospitalization odds.

New international guideline provides expert guidance for PET imaging of patients with coronary artery disease

A new clinical guideline has been issued for 18F-flurpiridaz PET myocardial perfusion imaging, providing recommendations for patient selection, imaging protocols, and interpretation of results. The guideline aims to enhance diagnostic accuracy and optimize resource utilization for the evaluation of coronary artery disease.

A graphene sandwich — deposited or transferred?

Researchers at Kobe University investigated how different manufacturing techniques affect the electronic structure of magnetic tunnel junctions. They found that the surface of ferromagnets is different when insulators are transferred to them compared to growing crystals on insulator flakes. This difference influences device behavior, p...

Age limits for social media and restrictions on addictive functions: Leopoldina discussion paper recommends better protection for children and adolescents

The Leopoldina discussion paper advocates for age limits and restrictions on addictive functions in social media to protect children and adolescents from negative effects. Researchers recommend setting a minimum age for access, restricting certain functions, and implementing policies to promote healthy social media use.

PolyU scholars pioneer smart and sustainable personal cooling technologies to address global extreme heat

Researchers at PolyU are pioneering next-generation personal cooling solutions using advanced textiles and intelligent wearables. Their innovations include spectrum-selective textiles, thermal insulation, ventilative and evaporative cooling, and AI-driven frameworks that deliver personalized, energy-efficient cooling.

Water flowed on ancient asteroid

A team of researchers discovered that liquid water once flowed on the ancient asteroid Ryugu, which was formed more than a billion years ago. The finding suggests that carbon-rich asteroids may have delivered much more water to Earth than previously thought, impacting models of the planet's early oceans and atmosphere.

Fresh hope for type 1 diabetes as daily pill that slows onset confirms promise at 2-year follow-up

A daily pill of baricitinib, a Janus kinase inhibitor, preserves insulin-producing beta cell function and slows type 1 diabetes progression in people recently diagnosed with the condition. The treatment's therapeutic effect is lost when it's stopped, justifying its testing in earlier stages to prevent or delay clinical diagnosis.

Study identifies candidates for therapeutic targets in pediatric germ cell tumors

Researchers have identified distinct immune profiles for different subtypes of pediatric germ cell tumors, which could lead to more targeted therapies. The study found that certain tumor subtypes respond well to immunotherapy and others exhibit an immunosuppressive environment, making them more aggressive.

New model can accurately predict a forest’s future

A new model developed by University of Illinois researchers can accurately predict fluctuations in the relative abundance of tree species in a forest. The model uses genomic data and a one-time tree count to forecast changes in forest diversity, which is crucial for understanding how forests will change in the future.

Tuning "tension" in nanowires: Researchers boost CO2-to-fuel conversion efficiency fivefold

Researchers at UESTC developed a novel method to enhance metal-halide perovskite photocatalysts by precisely controlling internal lattice tension, leading to a fivefold increase in CO fuel production. The strain modified the electronic structure, slowing down charge recombination and lowering the reaction barrier.
