Things are about to get… hairy.
Wait, are black holes fuzzballs, or are they hairless? The big quest to understand black holes continues in the form of new research about the fastest-spinning examples. Scientists have found that while most black holes follow a particular theorem about what falls inside, a black hole spinning fast enough can extend “hairs” all the way back into regular space.
An international team of astronomers today announced the discovery of a rare molecule — phosphine — in the clouds of Venus. This detection could point to extra-terrestrial “aerial” life in the Venusian atmosphere. Watch our summary of the discovery.

On Earth, phosphine gas is only made industrially or by microbes that thrive in oxygen-free environments.

Researchers used the powerful X-rays of the Advanced Photon Source to see the preserved remains of an ancient Egyptian girl without disturbing the linen wrappings. The results of those tests point to a new way to study mummified specimens.
The mummified remains of ancient Egyptians hold many secrets, from the condition of the bodies to the artifacts placed within the burial garments. Now a team of researchers has found a way to unwrap those secrets, without unraveling the mummies themselves.
Three years ago, researchers from Northwestern University, in preparation for an exhibit on campus, carefully transported a 1, 900-year-old mummy to the Advanced Photon Source (APS), a U.S. Department of Energy (DOE) Office of Science User Facility at DOE ’s Argonne National Laboratory. There scientists used powerful X-ray beams to peer inside the layers of linen and resin to examine the 2, 000-year-old bones and objects buried within.
Astronomers have found more than a thousand stars that once belonged to an ancient satellite galaxy inside our own.
Though it sounds like something straight out of science fiction, controlling the speed of light has in fact been a long-standing challenge for physicists. In a study recently published in Communications Physics, researchers from Osaka University generated light bullets with highly controllable velocities.
According to Albert Einstein’s principle of relativity, the speed of light is constant and cannot be exceeded; however, it is possible to control the group velocity of optical pulses.
Currently, the spatiotemporal coupling of optical pulses provides an opportunity to control the group velocity of three-dimensional non-diffraction optical wave-packets, known as “light bullets,” in free space.
Optics researchers from The University of Queensland and Nokia Bell Labs in the US have developed a new technique to demonstrate the time reversal of optical waves, which could transform the fields of advanced biomedical imaging and telecommunications.
Time reversal of waves in physics doesn’t mean traveling back to the future; it describes a special type of wave which can retrace a path backwards through an object, as if watching a movie of the traveling wave, played in reverse.
UQ’s Dr. Mickael Mounaix and Dr. Joel Carpenter, together with Dr. Nick Fontaine’s team at Nokia Bell Labs, are the first to demonstrate this time reversal of optical waves, using a new device they developed that allows full 3D control of light through an optical fiber.
Virgin Galactic will fly again when VSS Unity is ready.
A bad computer connection foiled Virgin Galactic’s attempt to reach space over the weekend, company officials said.
VSS Unity, Virgin Galactic’s newest SpaceShipTwo vehicle, lifted off Saturday morning (Dec. 12) from New Mexico’s Spaceport America beneath the wings of its carrier airplane, VMS Eve.
Am I reading this wrong? Sunelight is literally a cure / weapon against corona? Or am I missing something / making an incorrect logical link?
Researchers from Tel Aviv University (TAU) have proven that the coronavirus can be killed efficiently, quickly, and cheaply using ultraviolet (UV) light-emitting diodes (UV-LEDs). They believe that the UV-LED technology will soon be available for private and commercial use.
This is the first study conducted on the disinfection efficiency of UV-LED irradiation at different wavelengths or frequencies on a virus from the family of coronaviruses. The study was led by Professor Hadas Mamane, Head of the Environmental Engineering Program at TAU’s School of Mechnical Engineering, Iby and Aladar Fleischman Faculty of Engineering. The article was published in November 2020 issue of the Journal of Photochemistry and Photobiology B: Biology.
“The entire world is currently looking for effective solutions to disinfect the coronavirus,” said Professor Mamane. “The problem is that in order to disinfect a bus, train, sports hall, or plane by chemical spraying, you need physical manpower, and in order for the spraying to be effective, you have to give the chemical time to act on the surface. Disinfection systems based on LED bulbs, however, can be installed in the ventilation system and air conditioner, for example, and sterilize the air sucked in and then emitted into the room.
They’re another welcome weapon in the fight against fossil fuels.
After getting bodied in the news cycle for a few months, small modular nuclear startup NuScale Power has an additional potential path to the diverse energy market. In a new evaluation run by the U.S. Department of Energy’s Idaho National Laboratory, NuScale’s nuclear module performed effective catalysis for hydrogen.
