Nuclear Waste Could Become a Source of Tritium for Fusion Power

Material & Energy, Nuclear & Particles /

A looming shortage of fuel for nuclear fusion may have an unexpected fix. A physicist at Los Alamos National Laboratory (LANL) suggests that tritium for fusion reactors could be generated using nuclear waste left over from fission plants. If fusion energy becomes practical, it could revolutionize power production, delivering virtually limitless electricity on demand. Yet, […]

Why Some People Refrain from Engaging in Sex

Health & Fitness, Psychology /

Sexual activity significantly impacts overall well-being. During intercourse, the body releases a surge of hormones that help relieve pain, strengthen the immune system, reduce the risk of cancer, and alleviate symptoms associated with menopause. However, many adults choose to avoid sex, which can result in emotional distress, feelings of shame, and lowered self-esteem—for both the

Sunlight Alone Keeps These Tiny Aircraft Aloft

Aerospace, Space & Environment /

Earth’s mesosphere is often called a “no-fly zone.” The air there is far too thin for conventional aircraft. But new ultralight devices might challenge that limitation, staying aloft with nothing more than sunlight. Photophoresis as a Key to Mesosphere Flight This approach relies on photophoresis — a gas flow that occurs when light strikes an

An Artificial Tongue That Learns Flavors

Material Technology, Science /

Machines have long excelled at replicating sight and sound, but taste has remained much harder to capture in digital form. While previous efforts have produced artificial tongues specialized for sweetness, wine, or whisky, researchers in Beijing have now created a more versatile graphene oxide-based “tongue” that not only detects chemicals but also learns to recognize
