Researchers showed that COVID-19 survivors -- including those not sick enough to be hospitalized -- have an increased risk of death in the six months following diagnosis with the virus. They also have catalogued the numerous diseases associated with COVID-19, providing a big-picture overview of the long-term complications of COVID-19 and revealing the massive burden this disease is likely to place on the world's population in the coming years.

The highlight of the new chart is a wake of stars, stirred up by a small galaxy set to collide with the Milky Way. The map could also offer a new test of dark matter theories.

It's a common sight: pelicans gliding along the waves, right by the shore. These birds make this kind of surfing look effortless, but actually the physics involved that give them a big boost are not simple. Researchers have recently developed a theoretical model that describes how the ocean, the wind and the birds in flight interact.

The fearsome tyrannosaur dinosaurs may not have been solitary predators as popularly envisioned, but social carnivores with complex hunting strategies like wolves.

Researchers examined the shoulder assembly of Little Foot, an Australopithecus that lived more than 3 million years ago, and may have confirmed how our human ancestors used their arms.

The small rotorcraft made history, hovering above Jezero Crater, demonstrating that powered, controlled flight on another planet is possible.

Tarantulas are among the most notorious spiders, due in part to their size, vibrant colors and prevalence throughout the world. But one thing most people don't know is that tarantulas are homebodies. Females and their young rarely leave their burrows and only mature males will wander to seek out a mate. How then did such a sedentary spider come to inhabit six out of seven continents?

Scientists have identified a set of human genes that fight SARS-CoV-2 infection, the virus that causes COVID-19. Knowing which genes help control viral infection can greatly assist researchers' understanding of factors that affect disease severity and also suggest possible therapeutic options. The genes in question are related to interferons, the body's frontline virus fighters.

Volcanologists' ability to estimate eruption risks is largely reliant on knowing where pools of magma are stored, deep in the Earth's crust. But what happens if the magma can't be spotted?

Researchers report the discovery of a super-Earth orbiting the star GJ 740, a red dwarf star situated some 36 light years from Earth.

Scientists have figured out how to modify CRISPR's basic architecture to extend its reach beyond the genome and into what's known as the epigenome -- proteins and small molecules that latch onto DNA and control when and where genes are switched on or off.

Researchers have injected human stem cells into primate embryos and were able to grow chimeric embryos for a significant period of time -- up to 20 days. The research, despite its ethical concerns, has the potential to provide new insights into developmental biology and evolution. It also has implications for developing new models of human biology and disease.

With fossils few and far between, paleontologists have shied away from estimating the size of extinct populations. But scientists decided to try, focusing on the North American predator T. rex. Using data from the latest fossil analyses, they concluded that some 20,000 adults likely roamed the continent at any one time, from Mexico to Canada. The species survived for perhaps 2.5 million years, which means that about 2.5 billion lived…

A team of researchers reports realization of a multi-node quantum network, connecting three quantum processors. In addition, they achieved a proof-of-principle demonstration of key quantum network protocols.

In April 2019, scientists released the first image of a black hole in galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement was just the beginning of the science story to be told.

The human scream signals more than fear of imminent danger or entanglement in social conflicts. Screaming can also express joy or excitement. For the first time, researchers have demonstrated that non-alarming screams are even perceived and processed by the brain more efficiently than their alarming counterparts.

The muon is a tiny particle, but it has the giant potential to upend our understanding of the subatomic world and reveal an undiscovered type of fundamental physics.

Really big systems, like ocean currents and weather, work on really big scales. And so too does your plastic waste, according to new research.

A global science collaboration using data from NASA's Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station has discovered X-ray surges accompanying radio bursts from the pulsar in the Crab Nebula. The finding shows that these bursts, called giant radio pulses, release far more energy than previously suspected.

Every year, our planet encounters dust from comets and asteroids. These interplanetary dust particles pass through our atmosphere and give rise to shooting stars. Some of them reach the ground in the form of micrometeorites. An international program conducted for nearly 20 has determined that 5,200 tons per year of these micrometeorites reach the ground.

A research team has discovered that the Martian climate alternated between dry and wetter periods, before drying up completely about 3 billion years ago.

Scientists have shown that coral structures consist of a biomineral containing a highly organized organic mix of proteins that resembles what is in our bones. Their study shows that several proteins are organized spatially -- a process that's critical to forming a rock-hard coral skeleton.

A new study explains why people rarely look at a situation, object or idea that needs improving -- in all kinds of contexts -- and think to remove something as a solution. Instead, we almost always add some element, whether it helps or not.

The fossil skull of a woman in Czechia has provided the oldest modern human genome yet reconstructed, representing a population that formed before the ancestors of present-day Europeans and Asians split apart.

We are made of stardust, the saying goes, and a pair of studies finds that may be more true than we previously thought.

Researchers have confirmed for the first time that Pine Island Glacier in West Antarctica could cross tipping points, leading to a rapid and irreversible retreat which would have significant consequences for global sea level.

A single 'super photon' made up of many thousands of individual light particles: About ten years ago, researchers produced such an extreme aggregate state for the first time. Researchers report a new, previously unknown phase transition in the optical Bose-Einstein condensate. This is a overdamped phase.

A computer game that induces mice to experience hallucination-like events could be a key to understanding the neurobiological roots of psychosis, according to a new study.

Neurons lack the ability to replicate their DNA, so they're constantly working to repair damage to their genome. A new study finds that these repairs are not random, but instead focus on protecting certain genetic 'hot spots' that appear to play a critical role in neural identity and function.

A possible explanation for why many cancer drugs that kill tumor cells in mouse models won't work in human trials has been found.

A study has both good news and bad news for the future of African elephants. While about 18 million square kilometers of Africa -- an area bigger than the whole of Russia -- still has suitable habitat for elephants, the actual range of African elephants has shrunk to just 17 percent of what it could be due to human pressure and the killing of elephants for ivory.

A new study has found the first evidence of sophisticated breathing organs in 450-million-year-old sea creatures. Contrary to previous thought, trilobites were leg breathers, with structures resembling gills hanging off their thighs.

New research has shown in a rodent model that daily consumption of sugar-sweetened beverages during adolescence impairs performance on a learning and memory task during adulthood. The group further showed that changes in the bacteria in the gut may be the key to the sugar-induced memory impairment.
