Researchers have shown that pollen collected by honeybees contains Streptomyces bacteria that are endophytes, symbionts living inside plant tissue. These release antimicrobial compounds that inhibit common bacterial and fungal diseases of honeybees and crop plants. This discovery could be used to treat infections of honeybee colonies by introducing selected species of Streptomyces into the hive.

A research team has demonstrated that spectroscopy combined with partial least squares regression (PLSR) can accurately estimate plant leaf traits, but models built at one site often fail elsewhere.

Radiation therapy may offer a comparable and potentially safer alternative to repeat catheter ablation for patients with severe abnormal heart rhythms that can no longer be controlled with medication. In the first study to directly compare cardiac radiation with standard catheter ablation for ventricular tachycardia, patients treated with cardiac radiation experienced fewer complications with similar effectiveness at controlling disease. Findings will be presented today at the American Society for Radiation Oncology (ASTRO) Annual Meeting and published in the International Journal of Radiation Oncology • Biology • Physics (Red Journal).

Researchers of the University of Freiburg Cluster of Excellence CIBSS demonstrate that an actin scaffold stabilizes the cell nucleus upon mechanical stress.

This protective mechanism helps cancer cells to avoid dying during their migration in the body.

In the long term, targeted interventions in this mechanism could help to prevent metastases.

A University of Maryland-led study that followed over 1,200 animals across six continents challenges longstanding assumptions about animal movement and has implications for conservation and management of at-risk mammalian carnivores globally.

Some of the first animals on Earth were likely ancestors of the modern sea sponge, according to MIT geochemists who unearthed new evidence in very old rocks.
