Stevia compound enhances minoxidil for treating hair loss

11. oktober 2025 Rapporteret af AI

Researchers have found that stevioside, a natural sweetener from the Stevia plant, improves the skin absorption of minoxidil, a common treatment for pattern baldness. In mouse tests, a patch combining the two stimulated hair growth by reactivating follicles. This approach could lead to more effective natural therapies for millions affected by androgenetic alopecia.

Plant-based serum boosts hair growth in weeks

A new topical serum containing plant extracts and growth proteins has shown promising results in increasing hair density and thickness within 56 days. Developed by researchers in Taiwan, the treatment outperformed a placebo in a small clinical trial involving 60 adults. While encouraging, experts call for larger studies to confirm its efficacy.

2025 Nobel Prize in Physics awarded for macroscopic quantum tunneling

The 2025 Nobel Prize in Physics has been awarded to John Clarke, Michel H. Devoret, and John M. Martinis for their discovery of macroscopic quantum tunneling and energy quantization in an electrical circuit. Their work, conducted in the 1980s at the University of California, Berkeley, demonstrated quantum effects on a macroscale using a Josephson junction. The laureates will share $1.1 million, with the ceremony set for December 10, 2025, in Stockholm.

Hubble telescope images spiral galaxy NGC 6000

The NASA/ESA Hubble Space Telescope has captured a stunning image of NGC 6000, a spiral galaxy 102 million light-years away in the constellation Scorpius. The picture highlights stars of varying ages, from blue young clusters to a golden older core, while revealing faint remnants of past supernovae. An asteroid photobombed the shot, adding streaks to the cosmic scene.

Scientists uncover hidden energy mechanism in M87 black hole

Astrophysicists at Goethe University Frankfurt have simulated how the supermassive black hole M87* powers its massive particle jet using a new numerical code. Their findings reveal that magnetic reconnection, alongside the traditional Blandford-Znajek mechanism, extracts rotational energy from the black hole. This discovery explains the immense jets that influence galaxy evolution.

Study shows older fathers transmit more disease mutations through selfish sperm

A new study reveals that older men pass on significantly more disease-causing genetic mutations to their children due to the rapid proliferation of mutant sperm stem cells. Researchers found that the proportion of mutated sperm rises sharply with age, from 1 in 50 for men in their early thirties to nearly 1 in 20 by age 70. This phenomenon, driven by 'selfish' mutations, heightens risks for severe disorders in offspring.

Nobel prize in chemistry awarded for metal-organic frameworks

The 2025 Nobel prize in chemistry has been awarded to Susumu Kitagawa, Richard Robson, and Omar Yaghi for pioneering metal-organic frameworks, porous materials capable of storing and releasing gases like carbon dioxide. These structures, which self-assemble from metal ions and organic molecules, have vast potential for applications such as capturing pollutants and harvesting water from air. The committee praised their work for creating materials that can hold enormous volumes of substances in tiny spaces.

Electrons in graphene reach supersonic speeds for first time

Researchers have achieved a breakthrough by pushing electrons in graphene to supersonic speeds, creating a hydraulic jump similar to a sonic boom. This experiment, conducted using a microscopic nozzle, marks the first observation of such electron behavior. The findings could help resolve debates on electrically charged shockwaves.

Trio awarded 2025 Nobel Prize in Physics for quantum tunneling work

The 2025 Nobel Prize in Physics has been awarded to John Clarke, Michel Devoret, and John Martinis for their pioneering research on quantum tunneling in superconducting circuits. Their 1985 experiments demonstrated how quantum effects apply to complex systems, laying the foundation for modern quantum computers. Clarke expressed surprise at the recognition, noting the unexpected impact of their discovery.

Nobel prize awarded for developing metal-organic frameworks

The 2025 Nobel Prize in Chemistry has been awarded to three researchers for their pioneering work on metal-organic frameworks, or MOFs, structured polymers with precise geometries. Richard Robson, Susumu Kitagawa, and Omar Yaghi share the honor for creating materials that enable gas storage, filtration, and catalysis. Their innovations, starting around 1990, have opened new possibilities in chemistry and environmental applications.

Scientists prove moai statues walked using rocking motion

9. oktober 2025 Rapporteret af AI

Researchers have confirmed that ancient Rapa Nui villagers moved massive moai statues upright using ropes and a rocking technique. Experiments with replicas and 3D models demonstrate the feasibility of this method, resolving a centuries-old mystery. The findings highlight the ingenuity of the island's people with limited resources.

Gaia mission reveals causes of tumbling asteroids

Scientists using data from the European Space Agency's Gaia mission have explained why some asteroids tumble chaotically while others spin steadily, linking it to collision frequency. The findings, presented at the EPSC-DPS2025 Joint Meeting in Helsinki, show a gap in rotation speeds that divides asteroid populations and indicates most are loose rubble piles. This could improve strategies for deflecting hazardous asteroids.
