Ethylene sensor could help monitor plant health

Researchers developed an easy-to-use sensor that can sensitively detect changes in ethylene levels, a key hormone in plant health. The sensor uses a network of single-walled carbon nanotubes to monitor fluctuations in ethylene gas levels, with high sensitivity suitable for monitoring plants in the field.

Access to forbidden rings

Researchers at UNIGE have developed a new technique for creating chains of molecular rings that do not use standard chemical interactions but instead contact with large molecular surfaces. This discovery helps answer an old contradiction in classical chemistry and provides new prospects for molecular cyclization.

New technique has potential to protect oranges from citrus greening

Researchers identified peptides that trigger immune responses in multiple plant species, including citrus, potentially preventing or reducing yield loss from citrus greening. This discovery offers a new hope for the devastated citrus industry, where no resistant varieties are available and limited disease control measures exist.

Bad sleep habits can depress teens

A study by Flinders University found that bad sleep habits in teenagers are linked to negative thoughts, perfectionism, and an increased risk of depression. The researchers recommend alternative treatments for repetitive negative thinking and perfectionism, including encouraging regular bedtime routines and limiting screen time.

Patient navigators cut ER visits, hospitalization for high risk health care users

A study by TTUHSC investigators found that an interprofessional patient navigation program reduced emergency room visits and hospital admissions among high-risk patients. The program, which used DSRIP guidelines, resulted in a significant decrease in hospital utilization, with participants experiencing 1.13 ER visits per year compared ...

Common anti-parasite treatments used on cattle have devastating impacts on wildlife

A study by University of Sussex researchers found that common anti-parasite treatments for cattle have devastating impacts on dung beetles, key prey items for various bird and bat species. The treatments, which are widely used and available without veterinary oversight, can attract adult beetles and impair their larvae's development.
