AI-powered companionship: PolyU interfaculty scholar harnesses music and empathetic speech in robots to combat loneliness

Researchers at PolyU have discovered that combining music and empathetic speech in robots can foster a stronger bond between humans and machines. Music enhances the emotional resonance of on-screen robots, making interactions feel more real, but its impact diminishes over time.

Antarctica sits above Earth’s strongest “gravity hole.” Now we know how it got that way

A new study finds that Antarctica's gravity hole formed as a result of slow rock movements deep under the Earth's surface, which overlapped with major changes in the continent's climate system. The study suggests that future research could reveal how the shifting gravity may have encouraged the growth of ice sheets.

Magnetic resonance imaging opens the door to better treatments for underdiagnosed atypical Parkinsonisms

A new study uses advanced MRI to accurately diagnose progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD), two underdiagnosed conditions. This breakthrough enables precise clinical trials and transforms treatment options for patients with balance problems, falls, stiffness, or difficulties with speech and movement.

Evidence behind intermittent fasting for weight loss fails to match hype

A new Cochrane review suggests that intermittent fasting may not be an effective strategy for weight loss in overweight or obese adults. The study found no meaningful difference in weight loss between intermittent fasting and traditional dietary advice or doing nothing, highlighting the need for more research into this area.

Outdated mortality benchmarks risk missing early signs of famine and delay recognizing mass starvation

A recent paper by Columbia University researchers calls for a re-examination of how famine thresholds are defined, citing stark disparities in how famine mortality is assessed across contexts. The authors argue that widespread starvation may go unrecognized until it is well advanced due to the current classification system.

Tiny cell messengers show big promise for safer protein and gene delivery

Researchers have discovered that vesicles generated from cell-surface protrusions can deliver active proteins and genome-editing enzymes far more efficiently than conventional extracellular vesicles. This natural delivery system may enable the development of safer and more precise strategies for genome editing, regenerative medicine, a...

Scientists reveal major hidden source of atmospheric nitrogen pollution in fragile lake basin

A new study reveals that the Erhai Lake Basin in southwest China is releasing far more atmospheric nitrogen pollution than it absorbs, threatening regional air quality and ecosystem health. The imbalance creates a net surplus of over 8,200 metric tons annually, making the basin a major source of atmospheric nitrogen pollution.

Flipping and reversing mini-proteins could improve disease treatment

A team of researchers from Penn State and The University of Minnesota Medical School found that chemically changing the structure of a naturally occurring peptide can make it more stable and effective against antibiotic-resistant bacteria. The new shape imparted by the modified molecule allows it to physically degrade bacterial cell me...

A new pilot study in Long Beach found that heightened federal immigration enforcement is undermining democratic participation, even among U.S. citizens who fear for undocumented family members. The study identified three critical barriers: climate of fear, knowledge gaps, and practical constraints.

Modular assembly of chiral nitrogen-bridged rings achieved by palladium-catalyzed diastereoselective and enantioselective cascade cyclization reactions

Researchers developed a palladium-catalyzed tandem cyclization strategy to construct chiral bridged oxazole bicyclic skeletons with high diastereoselectivity and enantioselectivity. The method exhibits excellent substrate universality, providing an efficient route for synthesizing complex three-dimensional structures.

Parents’ alcohol and drug use influences their children’s consumption, research shows

A Brazilian study analyzing 4,280 adolescents and their guardians found that parental attitudes play a significant role in preventing alcohol and drug use among young people. The 'authoritative' parenting style, which combines acceptance and monitoring, is the most effective in mitigating the risk of repeated consumption patterns.

Protecting turfgrass from fungal foes

University of Delaware researchers have discovered a novel strain of Bacillus subtilis that helps plants resist soil-borne diseases and retain moisture. The microbe, UD1022, is effective in controlling dollar spot fungus but only when applied directly to leaves, not through soil treatment.

Deforestation in the Amazon raises the surface temperature by 3 °C during the dry season

A study using satellite data found that deforestation in the Amazon increases surface temperature by 3°C during the dry season, with a 25% decrease in rainfall. This leads to greater forest degradation, increased tree mortality, and susceptibility to forest fires, threatening biodiversity.

Batista Lab study reveals how local antibody feedback regulates B cell competition and promotes immune diversity

Researchers at Ragon Institute discovered that antibodies produced in germinal centers act as a 'brake' on selection, redirecting the immune system toward broader protection. Stronger-binding B cells suppress weaker ones targeting the same site, establishing a localized feedback loop.

How did humans develop sharp vision? Lab-grown retinas show likely answer

Researchers at Johns Hopkins University used lab-grown retinal tissue to discover the cellular mechanisms that shape the foveola, a critical part of the eye responsible for sharp vision. The findings suggest that blue cones convert into red and green cones during early development, rather than migrating to other parts of the retina.
