China: Liver helps revive dead pig’s brain after 50 mins of no oxygen

Posted by in categories: biotech/medical, neuroscience

Scientists in China have managed to revive brain activity in pigs nearly an hour after circulation ceased, thanks to the surprising involvement of the liver.

If translatable to humans, this finding could have significant implications for extending the critical window in which doctors can resuscitate patients following sudden cardiac arrest.

The research team, led by Dr. Xiaoshun He at Sun Yat-Sen University, experimented with the brains of 17 Tibetan minipigs to investigate how the liver might influence brain recovery.

The University of Alabama in Huntsville

Posted by in categories: particle physics, space travel

Two researchers at The University of Alabama in Huntsville (UAH) have published a paper that demonstrates for the first time that a subluminal warp drive is possible within the bounds of known physics without the need to employ exotic unknown forms of matter or energy, while also advancing our understanding of gravity. UAH alumnus Dr. Jared Fuchs led a team of physicists that produced the paper, supported by Dr. Christopher Helmerich, also an alumnus of UAH, a part of the University of Alabama System, both working in conjunction with the New York-based Applied Propulsion Laboratory of Applied Physics (APL).

When Mexican physicist Miguel Alcubierre first proposed his theoretical warp drive in 1994, the concept required a bubble of ‘negative energy density’ around an object to create an imbalance in space-time, generating motion without movement of the craft, thus avoiding violations of the speed-of-light limit. But the Star Trek dream comes with a catch: it would have to be powered by either exotic particles that haven’t yet been discovered, or the mysterious dark energy thought to drive the expansion of the universe, currently viewed by most physicists as not remotely achievable.

Fuch’s team’s Constant-Velocity Subluminal Warp Drive, however, offers a new means of propulsion that allows it to operate at constant subluminal speeds, while still conforming to Einstein’s theory of general relativity, with no need for ‘unphysical’ forms of matter required by previous designs.

Physicists discover first “black hole triple”

Posted by 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.

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 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.
