Nuclear fusion, the reaction that powers the Sun, has the potential to provide abundant clean energy on Earth.

Just one gram of deuterium-tritium fuel can generate the same energy as burning 2,400 gallons of oil without releasing any greenhouse gases.

Scientists worldwide are working to make fusion practical, but heating plasma to hundreds of millions of degrees Celsius is a challenge.

A new study from Princeton Plasma Physics Laboratory (PPPL) suggests that a Faraday screen could help achieve these extreme temperatures.

This breakthrough brings us closer to realizing the potential of clean, sustainable energy.

Love knows no bounds, even in the wild. In Russia’s far east, Boris, a young Siberian tiger, was given a second chance at life as part of an ambitious project to reintroduce these majestic creatures to their historic range. Raised in captivity, Boris was eventually released into the wild, but fate had different plans.

Driven by instinct, he traveled over 200 kilometers (124 miles) to reunite with Svetlaya, a female tiger raised alongside him. Their bond blossomed, and within months, they welcomed a litter of cubs.

This remarkable story is part of the Siberian tiger reintroduction project in the Pri-Amur region, a Russian territory bordering China. After a 50-year absence, Siberian tigers were reintroduced between 2012 and 2021.

Boris and Svetlaya were among six orphaned cubs raised in captivity, trained with live prey, and released with GPS collars to track their progress. The success of this project marks a hopeful chapter in the restoration of this iconic species.

The European Organization for Nuclear Research (CERN) has approved the high-luminosity Large Hadron Collider (HL-LHC) upgrade project, set to enhance the world’s largest and most powerful particle accelerator.

This upgrade will intensify the LHC’s beams, enabling the production of more data and allowing scientists to study rare particle interactions with greater precision.

The recent addition of two magnet assemblies to the Inner Triplet (IT) String at CERN marks an important step in testing new technologies for the HL-LHC, paving the way for exciting future discoveries in particle physics.

NASA's recent findings reveal that water found on Jupiter's comet, 67P/Churyumov–Gerasimenko, shares striking similarities with Earth's oceans.

Using data from the Rosetta spacecraft, scientists discovered that the comet's water molecules have a chemical composition closely matching Earth's, particularly in terms of the ratio of deuterium to hydrogen.

This discovery could provide significant insights into the origins of water on Earth and its potential link to comets that may have contributed to the planet's early water supply.

Australian researchers have developed a groundbreaking method to counter GPS jamming in drones by harnessing the power of stars.

This innovative technique uses star trackers, which are typically used in satellites, to provide alternative navigation data. By utilizing the consistent position of stars, drones can maintain accurate navigation even when GPS signals are disrupted.

This development is a significant step in enhancing the reliability and security of drone operations, especially in areas vulnerable to GPS interference.

NASA scientists have discovered the remains of a secret U.S. military base, Camp Century, buried 100 feet beneath the ice in Greenland.

Built during the Cold War in 1959-1960, Camp Century was intended to house nuclear missiles, though the plan never came to fruition and the base was abandoned.

Despite its closure, thousands of gallons of nuclear waste remain buried beneath the ice.

During an April flight over Greenland, NASA scientist Chad Greene captured radar images revealing the buried base. Initially, the discovery was puzzling, but further analysis confirmed it was Camp Century.

The base, consisting of 21 underground tunnels spanning 9,800 feet, was built in secrecy by the U.S. Army Corps of Engineers.

NASA used UAVSAR (Uninhabited Aerial Vehicle Synthetic Aperture Radar) technology to identify the structures. UAVSAR, similar to LiDAR, uses radio waves instead of laser light to detect hidden sites, making it effective in discovering buried structures like Camp Century.

Pilots spend about 90% of their time on autopilot, only engaging manually for takeoff and landing, which are the most challenging parts of flying.

During takeoff, the pilot must ensure the plane builds enough speed for lift, maintain coordination with air traffic control, and follow a precise path.

Landing is even more complicated: pilots must manage speed, direction, and descent, adjusting for wind and ensuring they land safely in the correct spot. The final steps include using brakes and reverse thrust to bring the plane to a complete stop.

While air traffic controllers can guide a passenger to land, it takes skill, practice, and knowledge—making it unlikely that an untrained passenger could execute a safe landing.

Researchers from MIT and Novo Nordisk have developed an innovative ingestible capsule inspired by squids' jet propulsion, capable of delivering drugs directly into the digestive tract.

This capsule could replace injections for treatments like insulin, antibodies, and RNA therapies for diabetes, obesity, and metabolic disorders.

Giovanni Traverso, senior author of the study, emphasized that this technology is a significant advancement in the quest to deliver macromolecules orally, improving the convenience and accessibility of treatments.

A recent study in the 2024 World Happiness Report reveals that young people are experiencing lower happiness levels than older generations, with many under-30s facing a "midlife crisis" earlier in life.

The research highlights that youth, particularly in North America and Western Europe, are struggling with issues such as economic inequality, social polarization, and the negative impact of social media.

This decline in well-being has contributed to the United States falling out of the top 20 happiest nations. Experts are calling for immediate policy action to address these growing concerns.

The Moon presents a harsh and inhospitable environment for potential explorers.

Given these extreme conditions, scientists and space agencies are increasingly looking to the Moon's subsurface as a potential refuge.

Over the past 20 years, satellite images have uncovered hundreds of large pits with overhanging ledges, suggesting the possibility of underground spaces like lava tubes—remnants of ancient volcanic activity.

While the search for these expansive, sheltered tunnels has been ongoing, definitive evidence remains scarce, fueling debate about the viability of lunar caves as safe for future lunar explorers.

The northernmost town in Alaska, is about to experience several weeks of darkness. After just 30 minutes of daylight.

The town saw its final sunset of the year and is now entering a "polar night." The sun won't rise again until January, marking the beginning of an extended period of darkness for 65 days.

On, November 18, 2024, Utqiagvik, Alaska, experienced its final sunset of the year at 1:27 p.m. The northernmost city in the United States will remain in darkness until January 22, 2025, as it enters the polar night.

During this period, the town will have no direct sunlight but will still experience a few hours of civil twilight, where dim light fills the sky. Situated deep within the Arctic Circle, Utqiagvik is the only U.S. city to undergo this extreme phenomenon, where, at times, the sun doesn’t rise or set for more than two months.

The town’s mayor, Asisaun Toovak, says that while people mostly stay indoors during the winter months, it’s also a time to rest. Despite the challenges, the town’s community, with many families having lived there for generations, thrives in the long winters, making the best of the long darkness and enjoying the Northern Lights.

In a groundbreaking first, researchers have successfully transferred atoms between optical tweezers using quantum tunneling.

This innovative approach builds on the work of American physicist Arthur Ashkin. This tool allows scientists to manipulate microscopic objects such as cells and molecules with precision, without physical contact.

The ability to transfer atoms via quantum tunneling not only demonstrates the versatility of optical tweezers but also opens new avenues for research in quantum mechanics and nanotechnology.
