Poaching affects behavior of endangered capuchin monkeys in Brazilian biological reserve

A study reveals that hunting pressure affects the behavior of endangered Yellow-breasted capuchin monkeys, causing them to avoid areas with abundant food sources due to increased risk of predation. The research suggests that poachers pose a significant threat, and the risk of predation outweighs the availability of food in their habitat.

New high-speed method for spectroscopic measurements

The new method uses polarization analysis to track changes in the spectrum of light on a nanosecond time scale over the entire color spectrum. By correlating polarization with laser color, researchers can measure spectral changes at high speeds, opening up new possibilities for material studies and astronomical observations.

Climate change may lead to more landfalling tropical cyclones in China

A study suggests that China will experience an increase in landfalling tropical cyclones by the end of the 21st century, with a projected 16% rise in annual mean frequency and a 10% increase in occurrence frequency. The study used regional climate models to simulate future changes in temperature and precipitation patterns.

Genetic cause of neurodevelopmental disorder discovered

A team of researchers at the University of Maryland School of Medicine has identified a new gene, AP1G1, that is associated with neurodevelopmental disorders and intellectual disabilities. The gene plays a crucial role in transporting essential materials within brain cells, and its disruption can lead to significant developmental delays.

Study: Removing 'bad apples' from police forces unlikely to significantly reduce use-of-force complaints

A new study suggests that replacing high-risk police officers with less likely to generate use-of-force complaints would reduce complaints by just 6 percent over a 10-year period. Researchers found that early warning systems and broader accountability measures are more effective in reducing misconduct.

HKU scientists reveal silver-based antimicrobials can be utilized as antibiotic adjuvants to combat antibiotic-resistant Staphylococcus aureus

Researchers at HKU have identified 38 authentic Ag+-binding proteins in Staphylococcus aureus, revealing silver's molecular targets and mode of action. The study shows that silver-based antimicrobials can potentiate the efficacy of antibiotics, resensitize MRSA to antibiotics, and slow down antibiotic resistance evolution.

Novel interactions between proteins that help in recovering from brain injury

Researchers discovered a novel interaction between proteins hevin and calcyon, which promotes synaptic contacts and reorganization in the brain. This interaction helps to improve recovery from brain injury, particularly in adults, by reducing neuroinflammatory response-induced proteases and promoting early stages of recovery.
