A plant’s nutrient-sensing abilities can modulate its response to environmental stress

(Carnegie Institution for Science) Understanding how plants respond to stressful environmental conditions is crucial to developing effective strategies for protecting important agricultural crops from a changing climate. New research led by Carnegie’s Zhiyong Wang, Shouling, Xu, and Yang Bi reveals an important process by which plants switch between amplified and dampened stress responses.

See how they run: ‘Exercise protein’ doubles running capacity, restores function and extends healthy lifespans in older mice

A new study shows that humans express a powerful hormone during exercise and that treating mice with the hormone improves physical performance, capacity and fitness. Researchers say the findings present new possibilities for addressing age-related physical decline.

Obese, snoring mini pigs show how air flows through the throat during sleep apnea

A study has found that obese Yucatan mini pigs have naturally occurring sleep apnea and that MRI scans taken while they’re in sedated sleep can be used to gain new insights into what happens in the airways during sleep apnea episodes via computational flow dynamic (CFD) analysis.

Pillar-like molecules as biosensors for metabolites

Researchers report that a molecule known as pillar[6]arene can form a host-guest compound with a cancer-associated metabolite. The phenomenon can be used to efficiently detect the metabolite in crude biological samples, which is important for preventing and treating metabolic syndrome and associated pathologies.
