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.

https://phys.org/news/2021-09-black-holes-exert-pressure-environment.html Black holes found to exert a pressure on their environment: Physicists at the University of Sussex have discovered that black holes exert a pressure on their environment, in a scientific first. In 1974 Stephen Hawking made the seminal discovery that black holes emit thermal radiation. Previous to that, black holes were believed to be inert, the final stages of a dying heavy star. The University of Sussex scientists have shown that they are in fact even more complex thermodynamic systems, with not only a temperature but also a pressure. The serendipitous discover…

Excerpt: The Japan Aerospace Exploration Agency (JAXA) has announced that it has successfully demonstrated the operation of a “rotating detonation engine” for the first time in space. The novelty of the technologies in question is that such systems obtain a large amount of thrust by using much less fuel compared to conventional rocket engines, which is quite advantageous for space exploration.

https://newatlas.com/physics/gravitational-waves-dark-matter-black-hole/ Never-before-detected gravitational waves hint at dark matter: A new type of gravitational wave detector running in Western Australia has recorded two rare events that might be signals of dark matter or primordial black holes. These high-frequency gravitational waves are beyond the range of most detectors and have never been recorded before. Gravitational waves are ripples in the very fabric of spacetime, first predicted by Einstein over a century ago but not directly detected until 2015. In the years since, dozens of detections have been made, mostly by facilities like LIGO, which can …

This looks like no hype at all. My feeling is that this has the makings of a real breakthrough in quantum computing. The possible implications for investigations in climate models, protein-folding, virology models, etc. are mouth-watering. I can't wait for the moment when this chip is finally built. https://phys.org/news/2021-08-critical-advance-quantum.html?fbclid=IwAR2mj_PP9NqXylVALnJQSbysOxzwF4HnU9_zFeNVTBiflnSrTq8phZdNUe0

One of the makers of the standard model. His influence in the world of physics in the second half of the 20th century has been only comparable to that of giants as Feynman, Gell-Mann, and 't Hooft. His books Dreams of a Final Theory and The First Three Minutes are a must-read for anybody willing to understand physics and how physicists think. He was notorious for his view of a universe without a purpose. …

On June 7, 2021, NASA’s Juno spacecraft flew closer to Jupiter’s ice-encrusted moon Ganymede than any spacecraft in more than two decades. Less than a day later, Juno made its 34th flyby of Jupiter. This animation provides a “starship captain” point of view of each flyby. For both worlds, JunoCam images were orthographically projected onto a digital sphere and used to create the flyby animation. Synthetic frames were added to provide views of approach and departure for both Ganymede and Jupiter.

The following is probably a well known, scientifically based story, about a time when the Earth suffered an almighty blow. It is lengthy, very lengthy, and at the same time detailed, very detailed. I actually followed it by the audio reproduction, which I recommend to others. As I said, very detailed and descriptive, and for an amateur novice such as myself, some of it quite revealing.
