A new AI-designed camera can only record objects of interest, erasing others through light diffraction, maximizing privacy protection. The camera is data- and energy-efficient, making it suitable for power-limited imaging applications.
A study of cardiology programs found that patients' documented DNR preferences are often suspended during TAVR procedures, with varying durations across programs. Only 26% had formal policies governing clinicians' responsibilities in these decisions.
Researchers designed high-fidelity Cas13 variants using mutagenesis to reduce collateral effects, demonstrating their feasibility and efficiency in mammalian cells and animals. The most promising variant, hfCas13d, showed marked reduction in off-target genes and no detectable collateral damage, supporting its potential for gene therapy.
A new study from Edith Cowan University found that exercising six times a day for five days can increase muscle strength by over 10% and improve muscle thickness. The research suggests that daily exercise is more beneficial for maintaining muscle mass and strength, rather than infrequent, longer workouts.
