Better methods and estimates of infectious disease burden

A new study uses a pathogen-based incidence approach to generate infectious disease burden estimates in Europe, attributing morbidity to specific pathogens. The methodology has limitations but shows the need for further research and integration of demographic changes and infection dynamics.

Long-term exposure to air pollution increases risk of hospitalization for lung, heart disease

A new study by Harvard researchers found a significant association between long-term fine particle air pollution exposure and higher rates of hospital admissions for pneumonia, heart attacks, strokes, and diabetes in older adults. The study used novel prediction models to estimate zip code concentrations of fine air particles and compa...

Orangutan nest building shows high degree of sophistication

A new study by researchers at the University of Manchester found that orangutans build nests with a high degree of sophistication, using strong branches for structural parts and weaker ones for linings. The apes' choice of branch was dictated by its diameter and rigidity, indicating possible knowledge of mechanical properties.

Depression may lead mothers to wake babies

Research found that depressed mothers are more likely to excessively worry about their infants' nighttime behavior and spend more time with them, leading to increased night waking in the infants. Mothers with high depressive symptoms were also more likely to seek out their babies at night, despite the infant not appearing distressed.

Institute of Physics: Medical schools should consider restoring the requirement for applicants to hold 'A' level or equivalent qualifications in physics

A study by the Institute of Physics suggests that requiring applicants to hold A-level physics qualifications could improve patient outcomes and diagnostic techniques. Medical schools are encouraged to revisit this requirement to provide students with a strong foundation in physics-based medicine.

Sunlight plus lime juice makes drinking water safer

Researchers found that adding lime juice to water treated with solar disinfection removed detectable levels of E. coli significantly faster than solar disinfection alone. The treatment time was comparable to boiling and other household methods, making it a potential effective solution for improving water quality in low-income regions.

Good vibrations in fight against cancer

Researchers at Case Western Reserve University have developed a magnetic nanochain delivery system that explodes chemotherapy drugs inside tumors, killing cancer cells more efficiently. The technology reduced tumor growth by up to 90% and increased survival rates in rats with triple-negative breast cancer.

The sea as a rubbish tip

A team of researchers has proposed standardised guidelines for the recording and characterisation of microplastic particles in the sea. By analysing 68 scientific publications, they found that the results are difficult to compare due to varying methods used. However, they discovered that using a net with a mesh of 85 micrometres can fi...
