The neonicotinoids we tested had an enormous effect on the quantity of sleep taken by both flies and beebs,” said Dr. Kiah Tasman, a researcher within the School of Physiology, Pharmacology, and Neuroscience at the University of Bristol.

“If an insect was exposed to an identical amount because it might experience on a farm where the pesticide had been applied, it slept less, and its daily behavioral rhythms were knocked out of synch with the traditional 24-hour cycle of day and night.” In the bumblebee study, exposure to the field-relevant concentration of the neonicotinoid insecticide imidacloprid reduced foraging activity, locomotion, and foraging rhythmicity. Foragers […]

The archosauriform footprints were spotted at a paleontological site on the Gardetta Plateau within the Western Alps, Italy.

The archosauriform footprints were spotted at a paleontological site on the Gardetta Plateau within the Western Alps, Italy. Most of the specimens are preserved as natural molds on top of a 3-4 cm thick bed of fine sandstone. They are shallow, but 2 cm deep, but most are cut by small-scale cracks/fissures and strongly weathered. Detailed view of the GT-1 and GT-2 trackways (highlighted) […]

Cloud-free exoplanets are exceedingly rare; astronomers estimate that but 7% of exoplanets have clear atmospheres.

Cloud-free exoplanets are exceedingly rare; astronomers estimate that but 7% of exoplanets have clear atmospheres. For example, the primary and only other known exoplanet with a transparent atmosphere, WASP-96b, was discovered in 2018. Astronomers believe studying exoplanets with cloudless atmospheres can cause a far better understanding of how they were formed. “Their rarity suggests something else goes on or they formed in a different way than most planets,” said Munazza Alam, an astronomer […]

Black holes are the key predictions of the general theory of relativity,

Black holes are a key prediction of the general theory of relativity,” said Queen Mary Emeritus Professor Bernard Carr and colleagues. “There are a plethora of observations indicating their existence within the solar or intermediate-mass range. especially, the existence of binary black holes within the mass range between 10 and 50 solar masses has been demonstrated by the detection of gravitational waves from inspiralling binaries.” “There is […]
