A weird star produced the fastest nova on record

Astronomers are buzzing after observing the fastest nova ever recorded. The unusual event drew scientists' attention to an even more unusual star. As they study it, they may find answers to not only the nova's many baffling ...

Decoding a key part of the cell, atom by atom

Whatever you are doing, whether it is driving a car, going for a jog, or even at your laziest, eating chips and watching TV on the couch, there is an entire suite of molecular machinery inside each of your cells hard at work. ...

Atmospheric helium levels are rising, research confirms

Scientists at Scripps Institution of Oceanography at UC San Diego used an unprecedented technique to detect that levels of helium are rising in the atmosphere, resolving an issue that has lingered among atmospheric chemists ...

Solar beats nuclear at many potential settlement sites on Mars

The high efficiency, light weight and flexibility of the latest solar cell technology means photovoltaics could provide all the power needed for an extended mission to Mars, or even a permanent settlement there, according ...

A versatile hydrogel network-repairing strategy

Hydrogen bond engineering can convey stretchability, toughness and self-healing properties to materials, although enhancement effects of conventional hydrogen bonds is limiting due to their weak interaction strength. For ...

Deep learning dreams up new protein structures

Just as convincing images of cats can be created using artificial intelligence, new proteins can now be made using similar tools. In a report in Nature, researchers describe the development of a neural network that "hallucinates" ...

NASA launches spacecraft to kick an asteroid off course

A NASA mission to deliberately smash a spacecraft into an asteroid—a test run should humanity ever need to stop a giant space rock from wiping out life on Earth—blasted off Tuesday from California.
