Today Chandra is continuing to study Cassiopeia A to better understand exactly how stars produce & disseminate many of the chemical elements found on Earth and in the cosmos at large! Take a “Journey through an Exploded Star” with Smithsonian Education & Chandra: http://s.si.edu/supernova
The Aldabra white-throated rail, a flightless bird that lives on its namesake atoll in the Indian Ocean, doesn’t look like anything special at first glance. But the small bird has big bragging rights, because it has effectively evolved into existence twice after first going extinct some 136,000 years ago.
According to a study published Wednesday in the Zoological Journal of the Linnean Society, the rail is an example of a rarely observed phenomenon called iterative evolution, in which the same ancestral lineage produces parallel offshoot species at different points in time. This means that near-identical species can pop up multiple times in different eras and locations, even if past iterations have gone extinct.
Fossils of the flightless bird were found both before and after Albadra was submerged by an “inundation event” that occurred around 136,000 years ago, said study authors Julian Hume, an avian paleontologist at Natural History Museum in London, and David Martill, a paleobiologist at the University of Portsmouth.

From the beginning of the year 2019, the sales of Boox eReaders slightly increase, and so do many other brands such as Kindle, Kobo and Sony. All of them suffered a rapid drop in sales in the previous year but now they are getting back. This may cause by the event that France prohibits students from using smartphones and tablets in schools.
Under the legislation passed in 2018, the French students as old as 15 were not allowed to bring their smartphones as well as tablets to schools from September. The law was originally noted in President Emmanuel Macron’s election campaign. Now, one semester has gone, actually what do folks think to this policy? Earlier than that, France endorsed a blanket smartphone ban for drivers, even those who park at the side of the road, so the further action to school is not that surprising. It seems that the French government is getting realized that the control of electronics use is significant to beat back the encroachment of digital technology in everyday life.
3D printing is moving ever closer to gaining a true home in mainstream commercial applications, thanks to the impact the technology is having on consumer fashion products such as jewelry, footwear, and clothing. While 3D printed fashion was still considered to be more of a novelty a few years ago, efforts have been increasing to make it more common – even in the classroom. Additionally, the technology is helping to usher in a more sustainable and eco-friendly way of manufacturing garments…and designer Julia Daviy is helping to lead the charge.
In addition to designing clothes, Daviy is also an ecologist and clean technology industry manager, and uses 3D printing to make cruelty-free, zero-waste clothing. She believes that the technology will change how the world produces clothing, especially when it comes to some of the more problematic issues of garment manufacturing, such as animal exploitation, chemical pollution, energy consumption, and material waste.
“Our goal was never to demonstrate the viability of 3D printed clothing and leave things at that. We’ll have succeeded when beautiful, comfortable, ethically manufactured and environmentally friendly clothes are the standard,” Daviy stated. “The innovations we’ve made on the production and marketing side of the equation are just as important as the technological breakthroughs that have gotten us this far.”

Art for humanity via technology, for the music geek in you Enjoy:-)
Ge Wang is an assistant professor at Stanford’s Center for Computer Research in Music and Acoustics (CCRMA).
His research focuses on programming languages and interactive software design for computer music, mobile and social music, laptop orchestras and education at the intersection of computer science and music. Wang is the author of the ChucK audio programming language, as well as the founding director of the Stanford Laptop Orchestra (SLOrk) and the Stanford Mobile Phone Orchestra (MoPhO). He is also the co-founder of Smule (which makes social music making apps and has over 100 million users) and the designer of the iPhone’s Ocarina and Magic Piano.

A documentary by Eric Merola
Burzynski: The Cancer Cure Cover-up is the story of a pioneering biochemist who discovered a unique and proprietary method of successfully treating most cancers. This documentary takes the audience on a near 50-year journey both Dr. Burzynski and his patients have been enduring in order to obtain FDA-approved clinical trials of Antineoplastons. Defying the face of skepticism, legal attacks from state and federal agencies, and a powerful propaganda campaign to stop Burzynski – this doctor and his patients are still going strong.
The multiplication of integers is a problem that has kept mathematicians busy since Antiquity. The “Babylonian” method we learn at school requires us to multiply each digit of the first number by each digit of the second one. But when both numbers have a billion digits each, that means a billion times a billion or 1018 operations.
At a rate of a billion operations per second, it would take a computer a little over 30 years to finish the job. In 1971, the mathematicians Schönhage and Strassen discovered a quicker way, cutting calculation time down to about 30 seconds on a modern laptop. In their article, they also predicted that another algorithm—yet to be found—could do an even faster job. Joris van der Hoeven, a CNRS researcher from the École Polytechnique Computer Science Laboratory LIX, and David Harvey from the University of New South Wales (Australia) have found that algorithm.
They present their work in a new article that is available to the scientific community through the online HAL archive. But one problem raised by Schönhage et Strassen remains to be solved: proving that no quicker method exists. This poses a new challenge for theoretical computer science.

AI Overlords
Musk has repeatedly warned of evil AI overlords in the past, saying that AI could become “an immortal dictator from which we could never escape” in a 2018 documentary called “Do You Trust This Computer?”
Most of what Neuralink is working on, including any plans for a brain computer interface, are still tightly under wraps. In one tantalizing clue, Bloomberg recently reported on a still unpublished academic paper by five authors who have been employed by or associated with Neuralink — though it’s unclear whether Musk’s tweet referred to their work.
