New analysis of critical limb-ischemia patients places best-cli trial into context within real-world setting

A new analysis of chronic limb-threatening ischemia (CLTI) treatment outcomes found that surgical revascularization is superior to endovascular treatment in patients with higher comorbidities. The study analyzed a broader clinical population than the BEST-CLI trial and found similar outcome rates for Medicare beneficiaries.

Room-temperature, solid-state synthesis of high-quality Cs3Cu2I5 thin films

Researchers at Tokyo Institute of Technology have successfully synthesized high-quality Cs3Cu2I5 thin films using a novel solid-state synthesis method. The team discovered that depositing CuI and CsI layers in specific ratios results in distinct local structures containing point defects, leading to highly efficient emissions.

Study finds cardiovascular risk score improves after one year of semaglutide use in patients with overweight and obesity

A study found that semaglutide use for one year decreases the 10-year atherosclerotic cardiovascular disease (ASCVD) risk score in patients with overweight or obesity. The treatment also leads to significant improvements in metabolic parameters, such as blood pressure, cholesterol, and fasting glucose levels.

Demystifying vortex rings in nuclear fusion, supernovae

A mathematical model developed by researchers at the University of Michigan could help engineers control the behavior of vortex rings in nuclear fusion and other applications. Vortex rings form during fuel compression and can disrupt the efficiency of fusion reactions. The model, which draws parallels with smoke rings, aims to understa...

This sustainable solution for removing phosphate and ammonium from wastewater promotes a circular economy

Researchers at University of Toronto Engineering have developed a sustainable solution to remove phosphate and ammonium from wastewater by utilizing advanced membranes incorporating inorganic particles. This method recovers these nutrients for future use, providing a new source of materials for agricultural fertilizers and helping addr...

Novel gene-editing strategy leverages unusual genetic alteration to block HIV spread in cells

Scientists at Temple University have developed a novel gene-editing strategy that disrupts the ability of HIV-1 virus to enter host cells by targeting a rare genetic disorder. This approach may offer another target for developing next-generation CRISPR technology for HIV elimination, while avoiding adverse effects on cell mortality.

Why do so many businesses fail? A new study suggests it has to do with when they're born

A new study suggests that a business's long-term success depends on its founding conditions, rather than changing market environments. Businesses founded in dynamic environments with functionally diverse teams tend to survive environmental change through slower decision-making and increased creativity.

New study shows noninvasive brain imaging can distinguish among hand gestures

A new study from UC San Diego shows that noninvasive brain imaging can distinguish among hand gestures with more than 85% accuracy. The research uses magnetoencephalography (MEG) to detect magnetic fields produced by neuronal electric currents, offering a safe and accurate option for developing brain-computer interfaces.

Human ancestry has been shaped by mixing and matching alleles

Recent studies reveal complex patterns of admixture in human populations, particularly in Africa and the Americas. In Africa, ancient introgression from Neanderthals and Denisovans contributed to increased genetic diversity, while in the Americas, modern admixture resulted in redistributed archaic ancestry.

New study finds common autism screening tool is effective but has limitations

A new study by UC Davis MIND Institute researchers and others finds that the M-CHAT-R/F screening tool is effective in identifying children with autistic traits, but it also flags many children incorrectly. The study highlights the need for clinical judgment and clear communication with parents about the limitations of the tool.

Next generation transcatheter aortic valve replacement system improves clinician deliverability, tracking and deployment in real-world setting

The next-generation Evolut FX TAVR system shows improved deliverability, tracking, and deployment compared to its predecessor. This is particularly beneficial for patients with difficult anatomies, where the new device's predictable deployment can improve coronary access, blood flow, and valve performance.

More than half of English patients with NSCLC in areas with low socio-economic levels do not receive new anti-cancer therapies

A study found that over half of English NSCLC patients living in low-socio-economic areas did not receive new anti-cancer therapies, despite having access to free treatment through the National Health Service. The researchers examined data from 90,785 patients diagnosed between 2012 and 2017.
