Engineers from the University of Nebraska–Lincoln have created a groundbreaking robotic skin that mimics nature’s ability to self-heal—no stitches or human assistance required.

The innovation:
The robotic “skin” is made from soft silicone embedded with liquid metal droplets, capable of detecting and responding to damage such as tears, pressure, or punctures. When a breach occurs, the system instantly redirects an electrical current to the affected area.

That current generates localized heat, melting the material and sealing the damage—much like how human skin forms a scab.

Once repaired, the system automatically resets itself, clearing the damage log so it’s ready to heal again in the future.

Inspired by both human and plant biology, this smart material could revolutionize everything from soft robotics and wearable tech to space exploration and prosthetics.

This self-repairing skin is a major step toward autonomous machines that can survive real-world environments without constant maintenance or human intervention.

Astronomers Discover the Hottest Brown Dwarf Ever!

Meet WD0032-317B — a record-breaking brown dwarf orbiting a white dwarf 1,400 light-years away, with a blazing day-side temperature between 7,250–9,800 K — hotter than the Sun’s surface (5,778 K)!

Spotted in a tight 2.3-hour orbit, this object is tidally locked, with a wild temperature swing of nearly 6,000 K between its day and night sides — far more extreme than even the famous exoplanet KELT-9b.

Key Highlights:

Mass: 75–88 Jupiter masses
Orbit: Just 2.3 hours around its white dwarf star
Host Star: 37,000 K, only 40% the mass of the Sun
Night Side: Cools to 1,300–3,000 K
Extreme UV Radiation is stripping its hydrogen-rich atmosphere apart

Why It Matters:
This discovery provides a rare window into how ultra-hot environments affect giant planets and brown dwarfs. It also shows how compact white dwarfs offer a unique observational advantage over larger stars like blue supergiants.

Title: “An irradiated-Jupiter analogue hotter than the Sun”
By: Na’ama Hallakoun et al.

Researchers at ETH Zurich, a leading science and technology university in Switzerland, have developed an innovative glow-in-the-dark wood using bioluminescent fungi.

The fungi used, such as Armillaria mellea (commonly known as honey fungus), naturally emit a greenish glow in the dark.

By integrating the fungal mycelium into the wood’s structure, scientists created a hybrid material that glows without the need for external power sources like electricity or batteries.

The project is part of a broader movement in sustainable design and living architecture, where biological systems are incorporated into buildings and public infrastructure.

The wood-fungi composite remains biodegradable and renewable, making it a highly eco-friendly alternative to traditional lighting solutions.

It offers a soft, natural light ideal for pathways, parks, or residential streets, especially in places aiming to reduce energy consumption and light pollution.

This research showcases how biodesign could shape the future of urban environments, blending nature with modern needs.

Beyond aesthetics, it also holds practical value for off-grid areas, emergency lighting, and artistic applications in urban planning.

Mars Is Spinning Faster — Thanks to NASA’s InSight Mission

New data from NASA’s now-retired InSight lander reveals a surprising twist: Mars is gradually speeding up its rotation, shortening the Martian day by a tiny amount — about a fraction of a millisecond per year.

What's causing this?
Scientists are still investigating, but possible explanations include mass shifts at the polar ice caps or changes deep within the planet’s interior. Unlike Earth, which slows down due to the Moon’s influence on our oceans, Mars has no oceans — hinting at a completely different mechanism.

These insights come from InSight’s RISE (Rotation and Interior Structure Experiment), which tracked subtle changes in radio signals between Mars and NASA’s Deep Space Network over 900 Martian days. The variations helped scientists measure the planet’s spin with extraordinary precision.

More than just spin:
The same data also refined our understanding of Mars’ core, confirming it has a large radius of about 1,835 km and a density between 5.9 and 6.3 g/cm³. Interestingly, the planet’s nutation (wobble) suggests that its core has uneven density, raising new questions about its internal structure.

Why it matters:
Though InSight’s mission ended in December 2022, its legacy lives on. The RISE experiment is considered historic, continuing to deepen our understanding of the Red Planet and its hidden depths.
