https://phys.org/news/2017-09-gravitational-oscillate-neutrinos.html Gravitational waves may oscillate, just like neutrinos: (Phys.org)—Using data from the first-ever gravitational waves detected last year, along with a theoretical analysis, physicists have shown that gravitational waves may oscillate between two different forms called "g" and "f"-type gravitational waves. The physicists explain that this phenomenon is analogous to the way that neutrinos oscillate between three distinct flavors—electron, muon, and tau. The oscillating gravitational waves arise in a modified theory of gravity called bimetric gravity, or "bigravity," and the physicists show that t…

It may sound pompous, and I totally got lost in my imagination with this. The Wits biomedical engineers have connected a human brain to the internet. Long story short, it streams brainwaves to the web, by converting the brain into an Internet of Things (IoT) node on the World Wide Web. (more, here: http://insaneclopedia.com/1468/brainternet-project-first-human-brain-linked-internet-real-time/) I feel like this is a huge step for machine learning and it will start getting a lot of interest.

CNN Money: China is capitalizing on mistakes made by the fossil fuel feudalists who reign over both parties in the US. It puts China on moral high ground compared to the US. It signals the demise of the fossil fuel industry. And, the effects on climate change are good.

The genetic basis of individual differences in attitudes, including personality traits, physical characteristics, and academic achievement. https://www.ncbi.nlm.nih.gov/pubmed/11414369 Wow....... So this study and claim are saying the person IQ , education achievement and academic achievement is base on genetics? If person dos really bad in school vs some one has PHD or tow PHD's is base on genetics? In others words if you smart or dumb is base on genetics? Or how well you do at school or your job?

"The new hydrogel is more than 50 times stronger than comparable squishy self-healing materials, researchers led by Takuzo Aida of the University of Tokyo report in the Jan. 21 Nature. Such substances are well suited for the body; they are 95 percent water. Hydrogels may one day serve as scaffolding for growing new tissue, as matrices for keeping drugs in their targeted area or as replacements for damaged cartilage. The new gel, unlike similar materials, is quick and relatively simple to make." http://www.sciencenews.org/view/generic/id/55483/title/Break_up_doesn%E2%80%99t_keep_hydrogel_down

As I'm sure many of you know, Bill Gates has received a lot of criticism regarding his philosophy of depopulation. The CEO of Microsoft believes, counterintuitively, that as the childhood mortality rate decreases, the population size will naturally decrease as they parents have no need to reproduce again in order to ensure they have surviving offspring. My question is this; Why do so may people disagree so strongly with his logic and philosophy?

https://phys.org/news/2017-09-interstellar-ice-birth-dna.html Could interstellar ice provide the answer to birth of DNA? September 14, 2017 Researchers at the University of York have shown that molecules brought to earth in meteorite strikes could potentially be converted into the building blocks of DNA. They found that organic compounds, called amino nitriles, the molecular precursors to amino acids, were able to use molecules present in interstellar ice to trigger the formation of the backbone molecule, 2-deoxy-D-ribose, of DNA. https://phys.org/news/2017-09-interstellar-ice-birth-dna.html http://pubs.rsc.org/en/Content/ArticleLanding/2017/S…

https://phys.org/news/2017-09-hubble-captures-blistering-pitch-black-planet.html Hubble captures blistering pitch-black planet September 14, 2017 This artist’s impression shows the exoplanet WASP-12b — an alien world as black as fresh asphalt, orbiting a star like our Sun. Scientists were able to measure its albedo: the amount of light the planet reflects. The results showed that the planet is extremely dark at optical wavelengths. Credit: NASA, ESA, and G. Bacon (STScI) Astronomers have discovered that the well-studied exoplanet WASP-12b reflects almost no light, making it appear essentially pitch black. This discovery sheds new light on the atmospher…

Just found the following "TED" video: It's just 18 minutes long and well worth watching. Any errors, alterations or corrections? Any other comment/s? ( I believe it should be shown at all schools starting at primary aged children). A great little explanatory talk in the most basic lay person's language.

A Chinese Company cooperated with Suzhou Canfuo Nanotechnology Co., Ltd, using acrylic fibers, dacron, chinlon and polypropylene fiber mixed respectively with superfine copper powder to make master batch which can be generated into fibers by melting in high temperature and then through Spinneret hole with high pressure. The fibers are woven to fabrics. So far, it has been already tested repeatedly and turned out that it can kill 90% bacteria. A new kind of antibacterial fabrics was invented. The principle of killing bacteria is that the tiny amount of super copper powder added in the fabrics has excellent function killing and anti-bacteria ability. …

So that makes the discovery of human-like footprints dating back 5.7 million years – a time when our ancestors were thought to still be getting around on ape-like feet – a surprising one. Further confounding the mystery is the fact that these prints were found in the Greek islands, implying hominins left Africa …

https://phys.org/news/2017-08-distant-galaxy-high-energy-radio.html Distant galaxy sends out 15 high-energy radio bursts August 30, 2017 by Robert Sanders A sequence of 14 of the 15 detected bursts illustrate their dispersed spectrum and extreme variability. The streaks across the colored energy plot are the bursts appearing at different times and different energies because of dispersion caused by 3 billion years of travel through intergalactic space. In the top frequency spectrum, the dispersion has been removed to show the 300 microsecond pulse spike. Capturing this diverse set of bursts was made possible by the broad …

This paper caught my eye. I've highlighted the point I found intriguing. "Fungi belong to one of the largest and most diverse groups of living organisms. The evolutionary kinship within a fungal population has so far been inferred mostly from the gene-information–based trees (“gene trees”) constructed using a small number of genes. Since each gene evolves under different evolutionary pressure and time scale, it has been known that one gene tree for a population may differ from other gene trees for the same population, depending on the selection of the genes. We present whole-genome information-based trees (“genome trees”) using a variation of a computational algorith…

https://phys.org/news/2017-08-theory-heavy-elements-primordial-black.html New theory suggests heavy elements created when primordial black holes eat neutron stars from within (Phys.org)—A team of researchers at the University of California has come up with a new theory to explain how heavy elements such as metals came to exist. The group explains their theory in a paper published in the journal Physical Review Letters—it involves the idea of primordial black holes (PBHs) infesting the centers of neutron stars and eating them from the inside out. https://phys.org/news/2017-08-theory-heavy-elements-primordial-black.html ::::::::::::::::::::::::::::::::::::::::::…

Astronomers using Caltech's Owens Valley Radio Observatory (OVRO) have found evidence for a bizarre lensing system in space, in which a large assemblage of stars is magnifying a much more distant galaxy containing a jet-spewing supermassive black hole. https://phys.org/news/2017-08-cosmic-magnifying-lens-reveals-jets.html#jCp

https://phys.org/news/2017-08-dino-killing-asteroid-earth-years-darkness.html Tremendous amounts of soot, lofted into the air from global wildfires following a massive asteroid strike 66 million years ago, would have plunged Earth into darkness for nearly two years, new research finds. This would have shut down photosynthesis, drastically cooled the planet, and contributed to the mass extinction that marked the end of the age of dinosaurs. extract: Scientists also calculate that the force of the impact would have launched vaporized rock high above Earth's surface, where it would have condensed into small particles known as spherules. As the spherules…

The galactic centre – the heart of the Milky Way, some 26,000 light-years from Earth – hosts a supermassive black hole with a mass 4 million times that of the Sun. Now, for the first time, scientists have accurately recorded the orbits of stars around thi…
