Promising minimally-invasive procedure fails to improve symptoms of emphysema in large international trial

A minimally-invasive procedure aimed at reducing lung inflation and shortness of breath in patients with severe emphysema has failed to demonstrate sustained long-term effects. Despite initial improvements, the procedure's durability was lacking, with no significant differences noted between treatment and sham groups after six months.

Mother's diet influences baby's allergies -- new research

Research published in The Journal of Physiology identifies a link between maternal diet and child allergies, finding that polyunsaturated fatty acids improve gut immune cell response. This may reduce allergy risk by accelerating the development of a healthy immune system.

800,000 years of abrupt climate variability

A team of scientists predicts that Earth's climate has undergone rapid transitions over the last 800,000 years, with evidence from ancient snow layers and volcanic eruptions. The study extends the current 100,000-year record to create a new testing ground for climate models.

Sick body, vigilant mind

A recent study found that when people have been recently sick, they are more likely to pay attention to and avoid others who might make them sick. This activation of the behavioral immune system is independent of conscious worries and is linked to a faster response in avoiding potentially contagious individuals.

Switching from coal to natural gas would do little for global climate, study indicates

A recent study suggests that relying on natural gas instead of coal would fail to significantly slow down climate change. The research found that a shift in energy sources could lead to a slight increase in worldwide warming over the next 40 years, with temperatures eventually dropping by only a few tenths of a degree.

The breathtaking dance of plants

Scientists at Norwich BioScience Institutes discovered that plant pores, essential for life and carbon cycles, are evenly spaced due to a specific protein called SPEECHLESS. This protein's activity helps create an even spatial pattern during plant growth, allowing plants to breathe efficiently in different environments.

Soybean rust PIPE: Past, present and future

The Soybean Rust Pest Information Platform for Extension and Education (PIPE) has saved farmers between $209-299 million since its introduction in 2005. The platform relies on accurate and timely monitoring data, weather data, and state-of-the-art information technology to provide essential management decisions.

Study in Tanzania finds fishery improvements outweigh fuelwood losses

A University of Rhode Island study found that Tanzania's Saadani National Park protects mangrove ecosystems while providing new income opportunities for local communities through increased fishing and shrimping activities. Mangrove cover declined by 27% before park establishment, but remained stable with reduced harvesting.

New limits on physician training hours could prove costly for US teaching hospitals

The new duty-hour limits will require US teaching hospitals to spend up to $1.3 billion a year on implementing the changes, which aim to reduce medical errors caused by fatigue. The reforms also introduce changes in the training environment, including standardized hand-overs and education on fatigue and patient safety.

McLean: Improvements are needed for accuracy in gene-by-environment interaction studies

A comprehensive review of the first decade of gene-by-environment interaction research in psychiatry found that novel findings were more likely to be published but also more likely to be false positives. The study suggests a focus on replication is necessary to confirm accurate correlations between genes and environmental variables.

White House's Childhood Obesity Task Force must focus on providing treatment for minority children

A recent U-M study highlights the need for a shared emphasis on both obesity prevention and treatment strategies to achieve the White House's goal of eliminating childhood obesity. The study concludes that prevention programs alone cannot effectively address the epidemic affecting minority children, who are disproportionately affected.

UH researchers work to develop screening method for superbug

Targeted policing has knock-on benefits

A new study by University College London found that targeted policing can lead to a reduction in crime not only in the targeted area but also in surrounding locations, known as 'diffusion of benefits'. Problem-oriented policing was shown to have the greatest positive effect on crime in nearby areas.
