Plant probe could help estimate bee exposure to neonicotinoid insecticides


Bee populations are declining, and neonicotinoid pesticides continue to be investigated -- and in some cases banned -- because of their suspected role as a contributing factor. However, limitations in sampling and analytical techniques have prevented a full understanding of the connection. Now, researchers describe a new approach to sample neonicotinoids and other pesticides in plants, which could explain how bees are exposed to the substances.

Older adults: Daunted by a new task? Learn 3 instead


Learning several new things at once increases cognitive abilities in older adults, according to new research. After just 1.5 months learning multiple tasks in a new study, participants increased their cognitive abilities to levels similar to those of middle-aged adults, 30 years younger. Control group members, who did not take classes, showed no change in their performance.

Newly-Discovered Rocky Exoplanet Has Three Red Suns


Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered a terrestrial planet orbiting a star in the triple-star system LTT 1445. LTT 1445, also known as TIC 98796344, TOI 455, L 730-18 or BD-17 588, is a hierarchical trio of mid-to-late M-dwarfs (red dwarf stars) approximately 22.5 light-years away. The newly-discovered world orbits LTT [...]
