The most common side effects of mRNA vaccines like the COVID-19 shot are well known: soreness, mild fever, and general malaise. Those symptoms, which typically resolve within days, are the natural result of the immune system ...
A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into each cubic parsec. The team ...
Estimating things that exist is generally easy, but when it comes to estimating things that do not exist, it's more difficult. This is something physicists from Poland and the UK are well aware of. To improve current simulations ...
Many fish appear to hang effortlessly in the water while they wait for prey, defend a nest or pause between bursts of activity. But our research shows that this quiet stillness is anything but effortless. Hovering, the behavior ...
For the first time in Brazil, researchers have identified a field of tektites. These are natural glasses formed by the high-energy impact of extraterrestrial bodies against Earth's surface. These structures, named geraisites ...
This week, researchers reported on a juvenile great white shark caught by fishermen in Spanish Mediterranean waters. China's clean air initiatives have resulted in major public health gains, but may have one unintended consequence. ...
Monarch butterflies have always been remarkably resilient. Every fall, these delicate orange-and-black travelers set out on a journey so improbable it borders on myth, flying some three thousand kilometers from Canadian fields ...
One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key finding was wave-particle ...
Greenland, the largest island on Earth, possesses some of the richest stores of natural resources anywhere in the world.
Experimental particle physicists working at the MicroBooNE experiment at Fermilab National Accelerator Laboratory have found evidence against the existence of a "sterile" type of neutrino hypothesized to be responsible for ...
