Scientists say new ‘water battery’ can hold more energy than lithium cells

Posted by in category: energy

Chinese scientists have developed a water-based battery with nearly double the energy density compared to traditional lithium batteries, according to new research published in a paper in Nature Energy.

According to researchers from the Chinese Academy of Sciences, tests revealed an impressive…


The iodine and bromine-based aqueous battery showed an energy density of 1,200 watt-hours per liter, surpassing the 700Wh/L of non-aqueous lithium batteries.

Unusual “Time-Travel” Creature Can Age in Reverse, Astonishing Scientists

Posted by in categories: life extension, time travel

A recent article in PNAS unveils a remarkable discovery: the ability for reverse development in a ctenophore, commonly known as a comb jelly. These findings indicate that life cycle flexibility in animals may be more widespread than previously believed.

Animal life cycles typically follow a familiar pattern, declined in countless variations: they are born, grow, reproduce, and die, giving way to the next generation. Only a few species are able to deviate from this general principle, the best-known example being the ‘immortal jellyfish’ Turritopsis dohrnii, which can revert from an adult medusa back to a polyp. This elusive group of animals with flexible life cycles now includes the ctenophore Mnemiopsis leidyi.

“The work challenges our understanding of early animal development and body plans, opening new avenues for the study of life cycle plasticity and rejuvenation. The fact that we have found a new species that uses this peculiar “time-travel machine” raises fascinating questions about how spread this capacity is across the animal tree of life,” said Joan J. Soto-Angel, a postdoctoral fellow in the Manet Team at the Department of Natural History at the University of Bergen.

This complete shell structure results in enhanced stability compared to isotopes with different configurations.

100 Sn is also the heaviest nucleus comprising protons and neutrons in equal numbers — a feature that enhances the contribution of the short-range proton–neutron pairing interaction and strongly influences its decay via the weak interaction,” CERN researchers remarked in a previous study.

“Understanding the nuclear properties in the vicinity of 100 Sn, which has been suggested to be the heaviest doubly magic nucleus with proton number Z (50) equal to neutron number N (50), has been a long-standing challenge for experimental and theoretical nuclear physics,” said the research team in the study.

Senescent Cells Promote Cartilage Regeneration in Rats

Posted by in categories: biotech/medical, life extension

In a rat experiment, researchers publishing in Aging Cell have found that senescent cells and SASP factors are key in regenerating knee cartilage.

Not always negative

Cellular senescence is widely known to have negative effects, to the point that it is one of the hallmarks of aging. In fact, rather than protecting cartilage, cellular senescence has been reported to damage it in the progression of osteoarthritis [1]. However, the idea that senescence is beneficial for regeneration is not a new concept [2], and it has been found to assist wound healing in mice [3]. Understanding everything involved in this complex relationship is not easy, and one of the factors appears to be windows of time [4].

Two Students Created Face Recognition Glasses. It Wasn’t Hard

Posted by in categories: robotics/AI, transportation

On a recent Friday afternoon, Kashif Hoda was waiting for a train near Harvard Square when a young man asked him for directions.


A month later, he found out just how strange. He had been an unwitting guinea pig in an experiment meant to show just how easy it was to rig artificial intelligence tools to identify someone and retrieve the person’s biographical information — potentially including a phone number and home address — without the person’s realizing it.

A friend texted Mr. Hoda, telling him that he was in a video that was going viral. Mr. Nguyen and a fellow Harvard student, Caine Ardayfio, had built glasses used for identifying strangers in real time, and had demonstrated them on two “real people” at the subway station, including Mr. Hoda, whose name was incorrectly transcribed in the video captions as “Vishit.”
