Researchers develop a new computational tool to understand how genetic interactions impact human traits

A new study developed a powerful computational method, FAME, to detect and quantify genetic interactions. The researchers found 16 instances of interactions on traits such as cholesterol and liver enzymes, which were larger than the effects identified by examining individual variants alone.

Flaring black hole whips up ultra-fast winds

Astronomers discovered a never-seen-before blast from a supermassive black hole, whipping up powerful winds at 60,000 km per second. The event was triggered by an X-ray flare and formed in just one day, providing new insights into the magnetism of active galactic nuclei (AGNs).

A dual-action strategy: Everolimus alleviates ulcerative colitis via inflammation suppression and microbiota remodeling

A new study reveals that Everolimus effectively inhibits the CLEC4E/Syk/NF-κB signaling axis, reducing pro-inflammatory cytokine production. The drug also alters the gut microbiota, restoring microbial diversity and enriching beneficial species, leading to improved barrier integrity and reduced inflammation.

ECU study could help conserve the world’s rarest marsupial

Researchers from Edith Cowan University analyzed the diet of fungi-eating mammals to determine if they could provide insights for conserving the critically endangered Gilbert's potoroo. The study found that examining the diets of co-existing species can help identify suitable habitats for translocations.

Recycling a pollutant to make ammonia production greener

Researchers have developed an electrocatalyst that efficiently converts nitrate into ammonia at low concentrations and gentle voltage. The catalyst reduces emissions linked to fertilizer and chemical manufacturing, and enables recycling of nitrate, a common pollutant found in groundwater and agricultural runoff.

Energy and regional factors drive carbon price volatility in China’s emissions trading markets

The study reveals clear regional differences in what drives carbon price volatility, with energy prices and industrial structures playing key roles. The proposed GM-AL model outperforms benchmark models and provides a scalable framework for other countries to establish or enhance their own ETS mechanisms.

Researchers from NUS Medicine and the Institute of Mental Health detect early brain changes linked to future psychosis development

The study used advanced neuroimaging methods to identify early, network-level changes in over 3,000 individuals at varying levels of risk for psychosis. Individuals at high clinical risk exhibited early disruptions in brain network organisation despite mild clinical symptoms.

Adaptive Kalman filter boosts BDS-3 navigation accuracy in challenging environments

A new PPP strategy integrates a covariance-adaptive Kalman filter to compensate for sudden orbit and clock jumps, improving horizontal, vertical, and 3D accuracy. Tests show significant gains in accuracy, demonstrating the algorithm's ability to deliver robust sub-meter real-time positioning even in network-limited environments.

Super-strong intelligent fiber that "adheres upon contact with water"

Researchers developed a copolymer hydrogel fiber with reversible humidity-responsive characteristics, achieving high mechanical strength in dry state and rapid transformation into adhesive state upon contact with water. The fiber's unique nano-confined phase-separated structure enables cyclical switching between adhesion and detachment.

New study reveals how natural humic substances reshape soil carbon cycling and boost antibiotic resistance

Researchers found that natural humification processes in soil can influence microbial communities and ecological risks. Artificial humic substances added to paddy soil showed a strong enrichment of genes related to carbohydrate metabolism, suggesting microbes quickly mobilize additional carbon.

Sport in middle childhood can breed respect for authority in adolescence

A new study by researchers in Canada and Italy suggests that young adolescents who participated in organized sports between ages 6 and 10 are less likely to defy authority figures. The study found that structured extracurricular activities can promote behavioral resilience and reduce the burden of disruptive behavior disorders.

ASH 2025: New data highlights promise of pivekimab sunirine in two aggressive blood cancers ​

Researchers present promising new data from two ongoing studies of pivekimab sunirine targeting CD123 in treating two aggressive blood cancers, acute myeloid leukemia (AML) and blastic plasmacytoid dendritic cell neoplasm (BPDCN). The triplet regimen including pivekimab sunirine showed high response rates and enabled stem cell transpla...

ASH 2025: Study connects Agent Orange exposure to earlier and more severe cases of myelodysplastic syndrome

A new national study reveals a strong link between Agent Orange exposure and the risk of developing myelodysplastic syndrome, with exposed veterans diagnosed at younger ages and experiencing more aggressive disease. The study found that those with MDS were nearly twice as likely to see their disease progress within two years after diag...

GLP-1 receptor agonists likely have little or no effect on obesity-related cancer risk

A systematic review and meta-analysis found that GLP-1 receptor agonists probably have little or no effect on the risk of thyroid, pancreatic, breast, or kidney cancer in patients with type 2 diabetes or overweight/obesity. However, longer-term studies are needed to clarify potential risks or benefits for other obesity-related cancers.
