Now, They Can Reproduce: By clustering free-floating stem cells together, ‘xenobots’ can assemble baby bots: Early last year, a team of researchers announced the world's first living machines—bundles of stem cells from African clawed frogs (Xenopus laevis) that could be programmed to accomplish certain tasks. The sand grain–sized cells could successfully move microscopic objects, whiz around Petri dishes and even self-heal, Katherine J. Wu reported for Smit…

https://phys.org/news/2021-12-astronomers-strangely-massive-black-hole.html Astronomers discover strangely massive black hole in Milky Way satellite galaxy: Astronomers at The University of Texas at Austin's McDonald Observatory have discovered an unusually massive black hole at the heart of one of the Milky Way's dwarf satellite galaxies, called Leo I. Almost as massive as the black hole in our own galaxy, the finding could redefine our understanding of how all galaxies—the building blocks of the universe—evolve. The work is published in a recent issue of The Astrophysical Journal. The team decided to study Leo I because of its peculiarity. Unlike most dwa…

The discovery finally confirms how a rare type of star in the universe forms and evolves. The new class of stars, described in this month's issue of the Monthly Notices of the Royal Astronomical Society, was discovered by postdoctoral fellow Kareem El-Badry using the Shane Telescope at Lick Observatory in California and data from several astronomical surveys.

The UCI-led FASER team used a smaller detector of the same type in 2018 to make the first observations of the elusive particles generated at a collider. The new instrument will be able to detect thousands of neutrino interactions over the next three years, the researchers say. Credit: CERN The international Forward Search Experiment…

https://phys.org/news/2021-11-pandemic-amazon-rainforest-clues.html The Amazon rainforest offers troubling clues: extracts: In the three decades since Darah Lady's widowed grandmother first arrived in this remote stretch of northern Brazil, clearing the jungle by hand to build a house for her 14 children, the family has pushed deeper and deeper into the Amazon. It has been driven by the frontier maxim that prosperity comes when nature succumbs to human dominion. Yet their growing outpost in northeastern Amazonas state—one of thousands of informal settlements throughout the world's largest rainforest—could imperil not only their children's future but al…

https://phys.org/news/2021-11-absolutely-bonkers-mars-artificial-magnetosphere.html Terraforming Mars is one of the great dreams of humanity. Mars has a lot going for it. Its day is about the same length as Earth's, it has plenty of frozen water just under its surface, and it likely could be given a reasonably breathable atmosphere in time. But one of the things it lacks is a strong magnetic field. So if we want to make Mars a second Earth, we'll have to give it an artificial one. The reason magnetic fields are so important is that they shield a planet from solar wind and ionizing particles. Earth's magnetic field prevents most high-energy charged particles from…

https://phys.org/news/2021-09-game-changer-hydrogen-production.html Graphical abstract. Credit: DOI: 10.1016/j.nanoen.2021.106463: Curtin University research has identified a new, cheaper and more efficient electrocatalyst to make green hydrogen from water that could one day open new avenues for large-scale clean energy production. Typically, scientists have been using precious metal catalysts, such as platinum, to accelerate the reaction to break water into hydrogen and oxygen. Now Curtin research has found that adding nickel and cobalt to cheaper, previously ineffective catalysts enhances their performance, which lowers the energy required to…

"Elemental carbon exists in different structural forms including graphite, diamond, fullerenes, and amorphous carbon. In nature, these materials are produced through abiotic chemical processes under high temperature and pressure but are considered generally inaccessible to biochemical synthesis or breakdown. Here, we identified and characterized elemental carbon isolated from consortia of anaerobic methanotrophic archaea (ANME) and sulfate-reducing bacteria (SRB), which together carry out the anaerobic oxidation of methane (AOM)." "In addition, we found that select methanogens also produce amorphous carbon with similar characteristics to the carbon from AOM consortia…

The "nearly total" lunar eclipse is expected overnight Thursday, Nov. 18, to Friday, Nov. 19, NASA said. "The Moon will be so close to opposite the Sun on Nov 19 that it will pass through the southern part of the shadow of the Earth for a nearly total lunar eclipse," NASA said on its website. The eclipse will last 3 hours, 28 minutes and 23 seconds, making it the longest in centuries, Space.com reported. more at link.......…

https://phys.org/news/2021-11-space-junk-station-astronauts-docked.html Space junk sends station astronauts into docked capsules: Space junk threatened the seven astronauts aboard the International Space Station on Monday and forced them to seek shelter in their docked capsules. The U.S. Space Command said it was tracking a field of orbiting debris, the apparent result of some type of satellite break-up. The astronauts retreated into their docked capsules early Monday, after being told of the last-minute threat. Mission Control had them close the hatches between the space station compartments again later in the day, as a safety precaution. "We are…

While it is not entirely unknown in birds, it is still interesting to see examples. As in this case, Californian Condors were found to reproduce without input from males, though one was present. https://academic.oup.com/jhered/advance-article/doi/10.1093/jhered/esab052/6412509

https://www.fastcompany.com/90687369/this-ingenious-wall-could-harness-enough-wind-power-to-cover-your-electric-bill I've run across art projects that pretended to be science over the years and didn't stand up to scrutiny, and this has a faint whiff of that given the lack of any detailed analysis. But it's an intriguing idea 20 mph wind is about 600 Watts/m^2 so even if you are only harvesting 10% of that energy, a 10m^2 wall gives you 600 W of electricity. 24 hours of that per day gives you 14.4 kWh, which is only about half of what's claimed, but my assumption of only harvesting 10% of the energy could be too low*. Seems like the ballpark is that the…

NASA's newest space telescope will face 29 "harrowing" days after launch as it makes its way to a deep-space destination nearly 1 million miles (1.6 million km) from Earth, the agency says in a new YouTube video. The video, called "29 Days on the Edge," was released Monday (Oct. 18). It focuses on the journey and 50 expected deployments the James Webb Space Telescope will undergo after its expected launch on Dec. 18. The…

https://phys.org/news/2021-10-team-approach-unveil-life-evaporation.html Team discovers a new approach to unveil the Origin of Life: Evaporation: The image shows the evaporation-induced phase separation process inside an all-aqueous sessile droplet (Scale bar: 500 microns). The droplet is initially single-phase with PEG (Polyethylene glycol) and dextran dissolved. Upon evaporation, the concentration of PEG and dextran increases and incompatibility arises, forming tiny dextran-rich droplets (green fluorescently labelled) dispersed in the continuous PEG-rich phase. These tiny dextran-rich droplets move towards the center of the sessile droplet with the inwar…

https://phys.org/news/2021-09-chinese-astronauts-earth-day-mission.html The launch of Beijing's first crewed mission in nearly five years coincided with the 100th anniversary of the ruling Communist Party. Three Chinese astronauts returned to Earth Friday after completing the country's longest-ever crewed mission, the latest landmark in Beijing's drive to become a major space power. The capsule carrying the trio deployed its parachute and landed in the Gobi desert at 1:34 pm local time (0534 GMT). "It feels very good to be back!," Tang Hongbo told state broadcaster CCTV after the 90-day mission, a record for China. "I want to say dad,…

The crew offshore in the Great Pacific Garbage Patch achieved our largest ocean plastic catch to date in a single extraction with System 002 on September 22nd 2021. This load amounts to 3.8 tons and concludes the last short test of the campaign. The next weeks will see the crew putting the system to longer tests, potentially harvesting significantly more. While we look forward to bigger catches, the reactions of the crew members as the deck gets filled with trash are already an indication of how close we are to proving the capacity and efficiency of our latest system.
