Protostars ‘sneeze’ and produce rings of gas and magnetic flux as they grow

Star light, star bright, baby stars blow rings alight

People with long COVID are at increased risk of developing cardiovascular disease, according to a new study from Karolinska Institutet published in eClinicalMedicine. The results show that the risk of conditions such as cardiac arrhythmias and coronary artery disease is higher even among those who were not hospitalized during the acute infection.

Long COVID has become an increasingly significant health problem worldwide, and a growing number of studies suggest that the condition can lead to secondary cardiovascular diseases. To date, research has mainly focused on people who were hospitalized, while the risks for those who stayed at home or were treated at a GP are less well known...

The electronics inside your phone, your car, and every satellite currently orbiting Earth share one critical weakness: heat. Push them past about 200 degrees Celsius and they start to fail. For decades, that thermal ceiling has been one of the hardest walls in engineering. Now a team at the University of Southern California may have just found a way around it.

In a study published in Science, researchers led by Joshua Yang, Arthur B...

In 2024, NASA’s Perseverance rover found surprising levels of Nickel in the Martian bedrock of an ancient river channel, called Neretva Vallis, which flowed into the Jezero crater. A new study, published in Nature Communications, has taken a closer look at the data collected from the region and researchers are seeing what could be remnants of ancient Martian life.

Nickel as a biosignature
Although nickel is not typically thought of as a major component of human life, it is important in many microbial metabolism functions...
