Unraveling the immunopathogenesis of Johne's disease

A study by Hokkaido University researchers has identified prostaglandin E2 (PGE2) as a key player in impairing the immune response of cattle affected by Johne's disease. The discovery offers hope for developing a method to control this chronic enteritis caused by Mycobacterium avium subsp. paratuberculosis.

Proper data analysis might be among Hurricane Maria's casualties

A Penn State demographer warns that Hurricane Maria's destruction may have crippled Puerto Rico's ability to gather and analyze accurate data, hindering the island's recovery and response to future emergencies. The lack of proper data collection services and analysis may lead to inadequate allocation of resources, including money and aid.

Flood risk denial in US coastal communities

A study by David Casagrande explores the attitudes and perception of flood risk in US coastal communities. Residents employ rationalizations such as scapegoating and social comparison to avoid making difficult decisions, rather than taking steps to mitigate damage. This research highlights the importance of addressing individual belief...

Biological ballet: Imaging technique reveals complex protein movements in cell membrane

Researchers have developed an imaging method for live cells that suppresses photobleaching, allowing observation of individual molecules for up to 400 seconds. This enables study of protein movements and interactions in the cell membrane, shedding light on cellular behavior and potential targets for cancer treatment.

Infant death study reveals dangerous sleep practices among babysitters, relatives, others

A study of over 10,000 infant deaths found that many were caused by unsafe sleep positions or environments. Licensed childcare providers were more likely to follow safe sleep guidelines than babysitters, relatives, and friends. The researchers urge parents to educate anyone caring for their children on safe sleep practices.

New study shows vegetation controls the future of the water cycle

A recent study published in the Proceedings of the National Academy of Sciences shows that vegetation plays a dominant role in Earth's water cycle, regulating future dryness and water resources. Plants' physiological responses to increasing CO2 levels have a major impact on evapotranspiration, long-term runoff, and soil moisture.

Antarctica retreating across the sea floor

Researchers from the University of Leeds have created the first complete map of how Antarctica's grounding line is shifting. The study found that eight of the ice sheet's largest glaciers are retreating at an extreme rate, with some losing over 25 meters per year.

Researchers develop injectable bandage

A team of researchers from Texas A&M University has developed an injectable bandage using a gelling agent commonly used in pastries, which can stop bleeding and promote wound healing. The injectable hydrogels are made with kappa-carrageenan and nanosilicates to form a controlled release of therapeutics.

Spear points prove early inhabitants liked to travel

Researchers at Texas A&M University found that early settlers in interior western Canada used the Pacific coastal route to reach temperate North America, contradicting traditional theories of migration. The fluted spear points provide evidence supporting new genetic models explaining how humans colonized the New World.
