Students Designed a Mission to Venus on the Cheap

Universe Today Feed - 10 hours 36 min ago

Sometimes, the best way to learn how to do something is just to do it. That is especially true if you're learning to do something using a specific methodology. And in some cases, the outcome of your efforts is something that's interesting to other people. A team from across the European Union, led by PhD candidate Domenico D'Auria, spent a few days last September performing just such an exercise - and their work resulted in a mission architecture known as the Planetary Exploration Deployment and Research Operation - Venus, or PEDRO-V.

Galaxies die earlier than expected

For a long time, scientists thought that only actively star-forming galaxies should be observed in the very early Universe. The James Webb space telescope now reveals that galaxies stopped forming stars earlier than expected. A recent discovery deepens the tension between theoretical models of cosmic evolution and actual observations. Among hundreds of spectra obtained with the Webb program RUBIES, the team has found a record-breaking galaxy that had already stopped forming stars during an epoch where galaxies are normally growing very rapidly.

Asteroid impact threat estimates improved for the Earth and the Moon

An international team is currently closely tracking the near-Earth asteroid 2024 YR4. The impact probability estimates for the year 2032 has been reduced from a peak of 3 percent to below 0.001 percent.

Insight from one of Milky Way's most extreme environments

In new images, scientists have gotten the closest look yet at Sagittarius C -- a 'stellar nursery' where clouds of gas and dust have collapsed to form thousands of new stars.

Miso made in space tastes nuttier

Miso is a traditional Japanese condiment made by fermenting cooked soybeans and salt. Researchers successfully made miso on the International Space Station (ISS). They found that the miso smelled and tasted similar to miso fermented on Earth -- just with a slightly nuttier, more roasted flavor. The team hopes this research will help broaden the culinary options available to astronauts, improving the quality of life for long-term space travelers.

Will AI Save Medicine

Science-based Medicine Feed - 18 hours 13 min ago

Modern medicine is facing many challenges. As the science of medicine advances, it gets harder and harder. We have, in a way, picked all the low hanging fruit. People are living longer, and their medical conditions are getting more challenging to understand and to treat. In order to continue making medical progress we need more advanced technology. This technology – like stem […]

Ultralight Dark Matter Could Explain Early Black Hole Formation

Universe Today Feed - 19 hours 6 min ago

Blackholes are a fascinating class of object to study. We have learned significant amounts over the years but one of the outstanding mysteries remains; how there were supermassive black holes with millions or even billions of times the mass of the Sun present in the first billion years after the Big Bang. Our current models of stellar mass black hole evolution and mergers cannot explain their existence. A new paper suggests that ultralight dark matter particles, like axions may have done the trick and provides a mass range for expected particles.

Weekend workouts can be as valuable as exercising throughout the week

Spaceflight Weakens Our Weight-Bearing Bones the Most

Universe Today Feed - 21 hours 9 min ago

As humans continue to make tentative progress out into the cosmos, the impact of space exploration on our fragile bodies is only beginning to be understood. We know that space travel decreases muscle and bone mass but a team of researchers have discovered which bones suffer the most! Using a group of mice that became astro-rodents for 37 days, they discovered that bone degeneration effective the femur most but not the vertebrae. They concluded that it’s our weight-bearing bones that suffer the most.

Social Robots Can Improve Astronauts' Mental Health

Universe Today Feed - Tue, 04/01/2025 - 10:38am

Many health problems are faced by astronauts who spend significant amounts of time in space. But perhaps one of the most insidious is the danger to their mental health. In particular, a prolonged sense of loneliness that could crop up as part of a long-term deep space mission could have dire consequences. A recent paper from Matthieu Guitton, the editor-in-chief of the journal Computers in Human Behavior: Artificial Humans and a researcher at the CERVO Brain Research Center in Quebec, proposes one potential solution to that risk - social robots.

Black Hole Found Consuming its Own History

Universe Today Feed - Tue, 04/01/2025 - 10:24am

One of the common misconceptions about black holes is that they devour not only matter, but also the history of that matter. So when a black hole forms, you can only guess how it came to be. That isn't entirely true. Informational history is only lost when matter crosses the event horizon, and perhaps not even then. The material surrounding a black hole still has a rich history. In a recent study, astronomers have used that history to uncover the origins of a black hole system.

LOOKING GLASS: Exploring Titan's Icy Hydrocarbon Cycle

Universe Today Feed - Tue, 04/01/2025 - 10:18am

Though wildly different in so many ways, Earth and Saturn's moon Titan have something important in common. Among all the objects in the Solar System, they're the only two with liquids on their surfaces. There are parallels in how the liquids move in cycles on both worlds and a new mission proposal outlines how we can understand Titan better by studying these parallel processes.

We know nanoplastics are a threat -- this new tool can help us figure out just how bad they are

Matter and energy from Science Daily Feed - Tue, 04/01/2025 - 10:15am
While the threat that microplastics pose to human and ecological health has been richly documented and is well known, nanoplastics, which are smaller than one micrometer (1/50th the thickness of an average human hair), are far more reactive, far more mobile and vastly more capable of crossing biological membranes. Yet, because they are so tiny and so mobile, researchers don't yet have an accurate understanding of just how toxic these particles are.

An efficient self-assembly process for advanced self-healing materials

Matter and energy from Science Daily Feed - Tue, 04/01/2025 - 10:13am
Self-healing coatings are advanced materials that can repair damage, such as scratches and cracks on their own. Researchers have developed an efficient method for preparing self-healing films consisting of alternating layers of highly cross-linked organosiloxane and linear polydimethylsiloxane (PDMS). Their film is more durable than conventional self-healing PDMS materials, offering superior hardness and greater thermal stability while self-healing at mild temperatures, paving the way for stronger, more reliable, and easier-maintained self-healing materials.
