Humans have suffered from tuberculosis for thousands of years and, even today, the disease kills more than 1 million people each year. Yet diagnosing cases remains a challenge. Why?

Physicists discover first “black hole triple”
Posted by Cecile G. Tamura in categories: cosmology, physics
In a recent discovery, astronomers have found that the black hole in the well-known low-mass X-ray binary (LMXB) system V404 Cygni is part of a much larger structure—a wide triple system.
Many black holes detected to date appear to be part of a pair. These binary systems comprise a black hole and a secondary object — such as a star, a much denser neutron star, or another black hole — that spiral around each other, drawn together by the black hole’s gravity to form a tight orbital pair.
Now a surprising discovery is expanding the picture of black holes, the objects they can host, and the way they form.

Jamie Dimon Says TikTok and Facebook Are a ‘Total Stupid Waste of Time’ and People Should Read Books Instead
Posted by Kelvin Dafiaghor in categories: finance, policy
Dimon was speaking at the Georgetown Psaros Center for Financial Markets and Policy’s annual Financial Markets Quality Conference when he was asked whether he had any advice for the students there.
“For most of you guys, turn off TikTok, Facebook. A total stupid waste of time,” Dimon said.

Supermassive black hole forms chimney and vent in center of Milky Way
Posted by Shubham Ghosh Roy in category: cosmology
Astronomers found the exhaust vent of a chimney at our galaxy’s center for the first time.
There is a supermassive black hole at the center of our galaxy that is nearly 17 times bigger than the Sun and can suck in over 1,800 Earths at once. This gigantic black hole goes by the name Sagittarius A* (Sgr A•.
In a new study, a team of researchers claims that Sgr A* has caused the formation of a chimney and an exhaust vent at the center of the Milky Way.

Scientists say new ‘water battery’ can hold more energy than lithium cells
Posted by Omuterema Akhahenda 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 Genevieve Klien 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.
