Aug 3, 2022 by News Staff

Insects are traditionally thought to respond to noxious stimuli in an inflexible manner, without the ability to modulate their behavior according to context. In new research, scientists from the United Kingdom and Poland investigated whether bumblebees’ attraction to high sucrose solution concentrations reduces their avoidance of noxious (painful) heat. Their results, published in the Proceedings of the National Academy of Sciences, show that the...

This artist’s impression shows what the binary system VFTS 243 might look like if we were observing it up close. The system, which is located in the Tarantula Nebula in the Large Magellanic Cloud, is composed of a hot, blue star with 25 times the Sun’s mass and a black hole, which is at least nine times the mass of the Sun. The sizes of the two binary components are not to scale: in reality, the blue star is about 200,000 times larger than the black hole. Image credit: ESO / L. Calçada.
