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.

When we move, it's harder for existing wearable devices to accurately track our heart activity. But researchers found that a starfish's five-arm shape helps solve this problem. Inspired by how a starfish flips itself over -- shrinking one of its arms and using the others in a coordinated motion to right itself -- scientists have created a starfish-shaped wearable device that tracks heart health in real time.

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.

An AI model trained on large amounts of genetic data can predict whether bacteria will become antibiotic-resistant. The new study shows that antibiotic resistance is more easily transmitted between genetically similar bacteria and mainly occurs in wastewater treatment plants and inside the human body.

Applied physicists have created a photon router that could plug into quantum networks to create robust optical interfaces for noise-sensitive microwave quantum computers.

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.

Researchers have developed an innovative method to study ultrafast magnetism in materials. They have shown the generation and application of magnetic field steps, in which a magnetic field is turned on in a matter of picoseconds.

Monitoring urban plant health traditionally requires extensive manual labor and botanical expertise, creating challenges for cities facing expanding green spaces, higher population densities, and increasing threats to plants. Now, researchers have developed 'Plant Doctor,' an artificial intelligence-based tool that could revolutionize plant health monitoring. The proposed system can track individual leaves in urban video footage and precisely quantify the damage from pests and diseases, enabling scalable, non-invasive urban plant management.

New research suggests that smartwatches could provide a more accurate picture of people's daily drinking habits than current methods. The technology could be a key element for future alcohol interventions.

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 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.

Smaller than a grain of rice, new pacemaker is particularly suited to the small, fragile hearts of newborn babies with congenital heart defects. Tiny pacemaker is paired with a small, soft, flexible wearable patch that sits on the patient's chest. The wearable patch detects irregular heartbeats and automatically emits pulses of light. The light then flashes on and off at a rate that corresponds to the correct pacing. After the tiny pacemaker is no longer needed, it dissolves inside the body.

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 […]

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.

Squeezing exercise into one or two days a week seems to have similar health benefits as doing the same amount of physical activity spread out throughout the week

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.

Travellers to Mars Need to Avoid the Dust

A termination letter obtained by New Scientist reveals that the Trump administration has gutted the office that runs the country’s only nationwide survey on drug use and mental health

Researchers have created a bilayer metasurface made of two stacked layers of titanium dioxide nanostructures, opening new possibilities for structuring light.

The concept of nothing once sparked a 1000-year-long war, today it might explain dark energy and nothingness even has the potential to destroy the universe, explains physicist Antonio Padilla
