NASA engineers on Saturday detected a liquid hydrogen leak in the Artemis I rocket before its second launch attempt. The Space Launch System rocket was originally set to launch from the Kennedy Space Center in Cape Canaveral, Fla., on Monday but was delayed after one of the rocket’s engines failed to condition to the correct temperature. A hydrogen leak also …

Apple’s iPhone 14 could be able to communicate using satellites, according to a new rumour. The phones will have satellite connectivity so that they can make emergency calls or texts through a satellite network, rather than traditional phone connections. Such features can provide connections to people in remote areas. At the moment, hikers and others who might find themselves out …

PULLMAN, Wash. – A team of researchers at Washington State University has developed a new method of recycling polyactic acid (PLA), a plastic often used in filament, plastic silverware and food packaging. The simple and efficient method converts PLA into a high-quality resin, which can then be used in 3D printing. “We found a way to immediately turn this into …

Never before have we been able to view the universe the way the James Webb Space Telescope is showing it to us now. Our naked eye would never be able to see what the telescope sees: travelling through light and space, James Webb can see the origins of the universe – something our minds can hardly begin to grasp. Working …

In some ways, bullying is like a virus; the behavior can seem to spread from person to person—especially from adult bullies to children in their care—and it may come with lasting damage to physical and mental health, especially to its child victims. Research indicates that when a student attends a school where there is a single teacher who uses bullying …

Recently, record-breaking heat waves have occurred in many parts of the world, from Delhi to the Pacific Northwest. To estimate the frequency and severity of such extreme events in the near future, a team of experts from the University of Washington (UW) and Harvard University has analyzed a range of possible heat impacts worldwide by the end of this century, …

A black hole is usually where information goes to disappear — but scientists may have found a trick to use its last moments to tell us about the history of the universe. In a new study, two University of Chicago astrophysicists laid out a method for how to use pairs of colliding black holes to measure how fast our universe …

The work in the journal Nature, hinges on a novel, reconfigurable alternative to integrated circuits. Integrated circuits are typically composed of multiple electronic components housed on a single semiconductor material, usually silicon, and they run all types of modern electronics, including phones, cars, and robots. Integrated circuits are scientists’ realization of information processing similar to the brain’s role in the …

Black holes don’t just swallow matter. They also spit it out. From their polar regions, they can launch massive jets of energetic plasma that travel at nearly the speed of light, stretch longer than our galaxy and last for many millions of years. Scientists who are part of the Event Horizon Telescope (EHT) project have announced they’ve imaged the magnetic …

The findings suggest that mothers who have had COVID-19, or asymptomatic exposure to the coronavirus, can provide some protection against the virus to their newborns through this antibody transfer. The authors of the new paper in JAMA Pediatrics hypothesize this may have implications for COVID-19 vaccines. Antibodies to the SARS-CoV-2 coronavirus in the blood of pregnant women cross the placenta …
