Moonbound astronauts check out their ride at Kennedy Space Center

CAPE CANAVERAL, Fla. — There were no tires to kick, but the quartet of astronauts on the Artemis II mission that aims to fly around the moon next year got their first look Tuesday at the spacecraft that will take them there. NASA astronauts Reid Wiseman, Victor Glover and Christina Koch along with Canadian astronaut Jeremy Hansen flew into Kennedy Space Center to view the Orion capsule that will take them on the roughly nine-day mission. It’s still on track to fly in late November 2024. “That’s real. That’s it,” Hansen said Tuesday, pointing over his shoulder to the capsule set up at the end o...

Looking back toward cosmic dawn − astronomers confirm the faintest galaxy ever seen

The universe we live in is a transparent one, where light from stars and galaxies shines bright against a clear, dark backdrop. But this wasn’t always the case – in its early years, the universe was filled with a fog of hydrogen atoms that obscured light from the earliest stars and galaxies.

Zebrafish are a scientist’s favorite for early-stage research – especially to study human blood disorders

Scientists have relied on animal models as an alternative to testing on human tissues and cells for decades. But not just any organism can adequately model how human cells behave. Researchers take into account how quickly the organism can mature, how many offspring it can produce and how often it can reproduce. When studying genetics and developmental biology, one of the most important qualities to consider is how similar the model organism’s genes are to human genes.

Although humans and fish certainly look very different, the zebrafish has proved to be an excellent model organism for scientists studying hematopoiesis, or the development of blood cells.

Cats first finagled their way into human hearts and homes thousands of years ago – here’s how

A few years ago, I had the opportunity to go on safari in southern Africa. One of the greatest thrills was going out at night looking for predators on the prowl: lions, leopards, hyenas.

As we drove through the darkness, though, our spotlight occasionally lit up a smaller hunter – a slender, tawny feline, faintly spotted or striped. The glare would catch the small cat for a moment before it darted back into the shadows.

Russia to launch lunar mission Friday, first in nearly 50 years

Russia said Monday it plans to launch a lunar lander this week after multiple delays, hoping to return to the Moon for the first time in nearly fifty years.

Russian space agency Roscosmos said it had scheduled the launch of the Luna-25 lander for the early hours of Friday.

Why pain is so hard to measure – and how our study of brainwaves could help

Every individual’s experience of pain is unique – but that makes it harder to treat. The experience of pain remains impenetrable to scientists because it is so variable. So researchers and clinicians still rely on subjective ratings, such as asking patients to rate their pain on a scale of zero to ten.

But my recent work, in collaboration with my colleague Enrico Schulz and his team, showed new insights into a type of brainwave called gamma oscillations that scientists think may be linked to pain perception.

U.S. scientists repeat fusion power breakthrough for 2nd time

U.S. scientists have achieved net energy gain in a fusion reaction for the second time since December last year, the Lawrence Livermore National Laboratory said on Sunday.

Scientists at the California-based lab repeated the breakthrough in an experiment in the National Ignition Facility (NIF) on July 30 that produced a higher energy yield than in December, a Lawrence Livermore spokesperson said.

Public interest vs. private homes: Climate change and erosion fuel disputes along Lake Michigan’s shoreline

Steve Coombs’ lakefront home used to quake when waves crashed along Ogden Dunes’ receding shoreline.

“At one point, my wife said, ‘Should we just move out? Should we just go to a hotel?’ I mean, it’s very unnerving,” he recalled.

Off Miami, scientists put corals to a heat-stress test. It’s survival of the fittest

MIAMI — With a gentle pat, Wajahat Shera cemented a four-inch staghorn coral fragment onto a patch of seafloor two miles east of Key Biscayne — one of many planted Friday as part of an unusual undersea experiment being run by University of Miami scientists. These corals, previously collected from a range of reefs off South Florida, are being put to a critical heat-stress test. Some likely won’t survive the high ocean temperatures off the state that threaten to devastate much of the natural reef tract. But if some do — and that’s the hope — it could help identify coral types more likely to endu...

New research examines emotional regulation in infants later diagnosed with autism spectrum disorder

A recent study published in Development and Psychopathology sheds light on the emotional and physiological differences observed in siblings of children with autism spectrum disorder (ASD). These siblings have an increased likelihood of being diagnosed with ASD themselves, making their development a crucial area of investigation.

Previous research has already identified physiological differences in typical children during emotionally charged tasks.

‘City killers’ and half-giraffes: how many scary asteroids really go past Earth every year?

Asteroids are chunks of rock left over from the formation of our Solar System. Approximately half a billion asteroids with sizes greater than four meters in diameter orbit the Sun, traveling through our Solar System at speeds up to about 30 kilometres per second – about the same speed as Earth.

Asteroids are certainly good at capturing the public imagination. This follows many Hollywood movies imagining the destruction they could cause if a big one hits Earth.

Is this the protein plant of the future? New study finds ‘sweetness gene’ that makes lupins tastier

If you walk into a bar in Italy, you might be served a dish of salty, nutritious snacks: lupin beans, a legume that has been eaten around the Mediterranean and in parts of the Middle East and Africa for thousands of years.

Lupins are very high in protein and fibre, low in carbs, have a low glycaemic index, and they’re easy to grow in a variety of climates. However, some varieties also contain high levels of unpleasantly bitter alkaloids.
