As you age you naturally lose neurons and muscle mass and experience a decline in fertility and wound healing ability. Previous research in animals has offered several potential techniques for turning back the biological clock in specific tissues, including exercise and calorie restriction. However, age reversal of blood cells or at whole organism level has so far been elusive.
Facing a growing uranium demand fueled by expanding nuclear energy, China is turning to the vast reserves hidden in its oceans.

Japanese researchers are making groundbreaking discoveries on the mechanisms of aging and working to apply them. As we age, senescent cells, or aged cells that have stopped dividing, accumulate, causing inflammation that can damage blood vessels and organs. Animal experiments have shown that removing these cells improves kidney function and reduces arteriosclerosis. They have led to the identification of a drug and development of a vaccine to eliminate the cells.
Disrupted sleep-wake and molecular circadian rhythms are a feature of aging associated with metabolic disease and reduced levels of NAD+, yet whether changes in nucleotide metabolism control circadian behavioral and genomic rhythms remains unknown. Here, we reveal that supplementation with the NAD + precursor nicotinamide riboside (NR) markedly reprograms metabolic and stress-response pathways that decline with aging through inhibition of the clock repressor PER2. NR enhances BMAL1 chromatin binding genome-wide through PER2 K680 deacetylation, which in turn primes PER2 phosphorylation within a domain that controls nuclear transport and stability and that is mutated in human advanced sleep phase syndrome.
Astronomers at the University of Warwick have made an exciting discovery—a rare, high-mass compact binary star system located just 150 light-years away in the Milky Way. This marks the first time such a system has been observed, offering valuable insights into the origins of type 1a supernovae.
Astronomers have confirmed a pair of white dwarfs on a collision course to become a type 1a supernova—the brightest cosmic explosion. This system, the heaviest of its kind ever identified, has a combined mass of 1.56 times that of the sun.
Separated by only 1/60th of the Earth-sun distance, the stars currently orbit each other in just over 14 hours. However, gravitational wave radiation will gradually draw them closer over billions of years. On the verge of their explosive end, the stars will orbit so rapidly that a single orbit will take only 30–40 seconds.
Scientists created a stem cell-based method to produce high-quality mitochondria at scale, enabling effective treatments for osteoarthritis and other diseases linked to mitochondrial dysfunction. Scientists have developed a groundbreaking method to mass-produce high-quality human mitochondria, a
A research group led by Takumi Kagawa and Masashi Kato at Nagoya University Graduate School of Medicine has discovered that using “a unique sound stimulation technology”—a device that stimulates the inner ear with a specific wavelength of sound—reduces motion sickness. Even a single minute of stimulation reduced the staggering and discomfort felt by people that read in a moving vehicle.
The results, published in Environmental Health and Preventive Medicine, suggest a simple and effective way to treat this common disorder.
“Our study demonstrated that short-term stimulation using a unique sound called ‘sound spice’ alleviates symptoms of motion sickness, such as nausea and dizziness,” Kagawa said. “The effective sound level falls within the range of everyday environmental noise exposure, suggesting that the sound technology is both effective and safe.”
