Researchers have successfully generated and visualized helical electromagnetic pulses, a long-sought form of light that twists through space and time. The achievement overcomes significant challenges and opens up new possibilities for technologies like ultrahigh-speed communications and precision imaging.

Surprising nanoscopic heat traps found in diamonds

Researchers discovered 'hot spots' around atomic defects in diamonds that briefly distort the surrounding crystal, affecting quantum-relevant defects. The findings indicate optical techniques used to control defects may unintentionally generate small pockets of heat, potentially affecting diamond-based quantum devices.

Increased risk of severe bacterial infection after high teenage BMI

A new study from the University of Gothenburg has found that high teenage BMI and poor physical fitness are associated with a higher risk of developing severe bacterial infections in adulthood. The study, which followed over 44,000 men for three decades, shows that even at high normal weight, individuals are already at increased risk.

Tec-Dara combination offers substantial improvement over standard second-line therapies for relapsed or refractory multiple myeloma

A new trial found that the Tec-Dara combination of teclistamab and daratumumab significantly improved progression-free survival in patients with R/R multiple myeloma, achieving an 83.4% rate compared to 29.7% for standard therapies. The treatment also showed better quality of life outcomes and was comparable in safety profile.

Cooperative Intermolecular Interactions Regulate Supramolecular Polymer Assembly

Researchers have successfully assembled higher-order supramolecular polymers through cooperative interactions between aryl barbiturate molecules. The study's key findings include the intentional weakening of p-conjugated core interactions to promote alkyl−alkyl interactions, resulting in unique assembly and disassembly behavior.

Residential solar panels can raise electricity rates

A modeling study reveals that increasing numbers of households with rooftop solar panels can lead to higher rates for those without their own solar system. As the cost of solar systems falls, more customers defect from the grid, leading to increased rates and a 'utility death spiral' that disproportionately affects low-income households.
