A heavily used group of pesticides, designed to kill insects upon contact, is also poisoning bee colonies. Scientists have discovered a way to deliver an antidote using pollen-like microparticles. The medicine is composed of a special enzyme that can break down certain groups of insecticides called organophosphates. These insecticides pose a deadly threat, but if the

Astronomers have created the most comprehensive map yet of all the dark matter in the universe. That’s no easy feat, considering dark matter is invisible. Scientists know this shadowy cousin of regular matter exists, though, because its strong gravitational forces can pull entire galaxies together. Based on observations of its influence, astronomers estimate that dark

A “lost” letter written by Albert Einstein to a rival physicist recently sold to an anonymous collector for US$1.2 million at auction. The handwritten letter includes Einstein’s famous E=mc2 equation and is one of just four known examples of the equation in the physicist’s own handwriting, according to archivists from the Einstein Papers Project at Caltech and

Russia is planning to send a nuclear-powered spacecraft to the Moon, then Venus, then Jupiter. Roscosmos, Russia’s federal space agency, announced Saturday that its “space tug” – the term for a spacecraft that transports astronauts or equipment from one orbit to another – is scheduled to launch on an interplanetary mission in 2030. The spacecraft’s energy module,

If you have an overreaction to ‘triggering’ sounds such as other people chewing or drumming their fingers, you probably have misophonia. Now, scientists have discovered a key brain connection responsible for setting it off. The connection runs from the auditory cortex (the brain’s hearing center) to the orofacial motor cortex (controlling movement of the face, mouth

The Red Planet, called that for its rusty oxidized soil, looks vastly different to our planet’s green and blue appearance. Well, at least usually. The two planets can also appear incredibly similar, as European Space Agency astronaut Thomas Pesquet discovered while taking a photo of Earth looking decidedly red earlier this month, while onboard the

Almost 60 years after British nuclear tests ended, radioactive particles containing plutonium and uranium still contaminate the landscape around Maralinga in outback South Australia. These “hot particles” are not as stable as we once assumed. Our research shows they are likely releasing tiny chunks of plutonium and uranium which can be easily transported in dust
