Environmental Factors for Humans Standing on Titan

Universe Today Feed - Mon, 04/28/2025 - 8:49pm

What will a human experience while standing on the surface of Saturn’s largest moon, Titan, even with the protection of a pressurized spacesuit? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as William O’Hara, who is the Executive Director of Explore Titan investigated what physical attributes a human will experience when standing on Titan’s surface. This study has the potential to help scientists, engineers, mission planners, and the public better understand the risks associated with sending humans to far-off worlds for long periods of time and how to develop technologies to mitigate these risks.

A Dark Nebula with a Starry Background

Universe Today Feed - Mon, 04/28/2025 - 7:46pm

Star birth is a process hidden inside dense crèches of gas and dust. Yet, if you know what to look for, you can see the products of this essential cosmic process across the sky. The Circinus West molecular cloud is a starbirth crèche some 2,500 light-years away. It boasts everything from dark nebulae to protostellar objects and newborn stars to the faint ghosts of stars that have already died.

Viewing organs in 3D

Matter and energy from Science Daily Feed - Mon, 04/28/2025 - 7:21pm
It is now possible to obtain three-dimensional, high-resolution images of enzyme activity in tissue samples or whole organs -- thanks to probe molecules that anchor fluorescent dyes within tissue as they are activated by enzymes. The organ being mapped is made transparent by a clearing process. This allowed for visualization of differences in aminopeptidase N activity and the effects of inhibitors in mouse kidneys.

New AI model improves MS diagnostics

Computers and Math from Science Daily Feed - Mon, 04/28/2025 - 7:19pm
To provide the right treatment for MS, it is important to know when the disease changes from relapsing-remitting to secondary progressive, a transition that is currently recognized on average three years too late. Researchers have now developed an AI model that can determine with 90 per cent certainty which variant the patient has.

Smart surfaces: A powerless solution to multipath signal interference

Matter and energy from Science Daily Feed - Mon, 04/28/2025 - 7:19pm
Multipath interference disrupts wireless signals, causing issues like TV ghosting and fading. Now, researchers have developed a passive metasurface that overcomes traditional filtering limits. Using a time-varying interlocking mechanism with field-effect transistors, it transmits the first signal while blocking delayed ones from other angles -- without power or processing. This innovation enables low-cost, reliable wireless communication, which is ideal for IoT applications and environments prone to interference.

Dual scalable annealing processors: Overcoming capacity and precision limits

Matter and energy from Science Daily Feed - Mon, 04/28/2025 - 7:19pm
Combinatorial optimization problems (COPs) arise in various fields such as shift scheduling, traffic routing, and drug development. However, they are challenging to solve using traditional computers in a practical timeframe. Alternatively, annealing processors (APs), which are specialized hardware for solving COPs, have gained significant attention. They are based on the Ising model, in which COP variables are presented as magnetic spins and constraints as interactions between spins. Solutions are obtained by finding the spin state that minimizes the energy of the system.

Layered semiconductor shows potential for next-gen data storage

Matter and energy from Science Daily Feed - Mon, 04/28/2025 - 7:19pm
A squishy, layered material that dramatically transforms under pressure could someday help computers store more data with less energy. That's according to a new study that shows a hybrid zinc telluride-based material can undergo surprising structural changes when squeezed together like a molecular sandwich.

'Wood you believe it?' Engineers fortify wood with eco-friendly nano-iron

Matter and energy from Science Daily Feed - Mon, 04/28/2025 - 7:17pm
With more than 181.5 billion tons of wood produced globally each year, a new method could revolutionize how we build sustainably. By infusing red oak with ferrihydrite using a simple, low-cost process, researchers strengthened the wood at the cellular level without adding weight or altering flexibility -- offering a durable, eco-friendly alternative to steel and concrete. The treated wood retains its natural behavior but gains internal durability -- paving the way for greener alternatives in construction, furniture and flooring.
