Immunotherapy drug delays onset of Type 1 diabetes in at-risk group

A new trial shows that immunotherapy drug teplizumab can delay the onset of Type 1 diabetes in people at high risk by an average of five years compared to a placebo. The study, published in Science Translational Medicine, found reduced T-cell damage and improved insulin-producing beta cells in those who received the treatment.

Common dolphin populations at risk

A genomic study of over 500 common dolphins across 1,500 sq km reveals complex population structure and connectivity across state and international jurisdictions. The research emphasizes the importance of inter-jurisdictional collaboration to mitigate fisheries interactions and protect dolphin populations.

Chemists boost boron's utility

Researchers have created a boron-containing chemical group that is 10,000 times more stable than its predecessors. This new group, called benzoxaboralone, can be added to compounds to provide desirable attributes such as improved protein-binding strength.

'Best case' goals for climate warming which could still result in massive wildfire risk

Researchers found that a half-degree of additional warming would likely create a notably greater danger of fire on continents like the Amazon and African savanna, and around the Mediterranean. Suppressing extra warming could reduce climate-driven extreme fire activities in many places, potentially saving lives and billions of dollars.

Climate change 'winners' may owe financial compensation to polluters

A study by Princeton University researchers suggests that climate change can have both positive and negative effects on different groups. Those harmed by climate change should be compensated first, while those benefiting from it may receive payment afterwards. The approach aims to correct incentives and promote fairness in climate policy.

Study links kidney stones with bone problems

Researchers analyzed nationwide data to find a strong correlation between kidney stones and osteoporosis or bone fracture diagnoses. The study suggests that bone density screening may be necessary for individuals with kidney stones, particularly middle-aged and older men at risk of osteoporosis or fracture.

Neuroimaging reveals how ideology affects race perception

Research using neuroimaging found that white conservatives exhibit higher sensitivity to racial ambiguity in the anterior insula, leading them to overcategorize mixed-race faces as Black. This effect is linked to an affective reaction to racial mixing rather than a sensitivity to Blackness.

An ultra-degree-of-freedom structured vector beam

Scientists have successfully created a vector beam with an unprecedented 5 degrees of freedom, exceeding the previously reported 2 DoFs. This breakthrough exploits ray-wave duality in a frequency-degenerate laser to generate a non-separable output that combines periodic number, transverse index, oscillating phase, and astigmatic degree.

Mental health treatment rate rose early in pandemic

A study published in The Journal of Clinical Psychiatry found a significant increase in mental health treatment visits, particularly for substance use and anxiety, during the early stages of the COVID-19 pandemic. This rise is attributed to the challenges posed by shelter-in-place orders and the shift to virtual care.
