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…

Hi, there´s an awesome experiment trending right now: it shows the change of weight of sd cards when they are full of data. My question: is it necessary to use big sd cards like in the video or will it work with for example 64 gb cards? best regards

https://phys.org/news/2017-08-atlas-evidence-light-by-light.html ATLAS observes direct evidence of light-by-light scattering: August 15, 2017 by Katarina Anthony Physicists from the ATLAS experiment at CERN have found the first direct evidence of high energy light-by-light scattering, a very rare process in which two photons – particles of light – interact and change direction. The result, published today in Nature Physics, confirms one of the oldest predictions of quantum electrodynamics (QED). "This is a milestone result: the first direct evidence of light interacting with itself at high energy," says Dan Tovey(University of Sheffield), ATLAS …

Less than a year after they launched the world’s only quantum communications satellite, Chinese researchers have for the first time ever sent entangled photons from space to ground stations on Earth. “This is the first step towards worldwide secure quantum communications, and maybe even a quantum internet,” says Anton Zeilinger, an expert on quantum physics at the University of Vienna in Austria. One of the building blocks of a secure quantum network is the ability to exchange entangled photons between two parties. When a pair of photons are entangled particles, measuring one instantly influences the state of the other, regardless of the distance between them. …

http://www.virgo-gw.eu/docs/AdV_joins_O2_en.pdf VIRGO joins LIGO for the “Observation Run 2” (O2) data-taking period Today, Tuesday August 1st 2017, the VIRGO detector based in Europe has officially joined “Observation Run 2” (O2) and is now taking data alongside the American-based twin LIGO detectors. This major step forward for the VIRGO Collaboration is the outcome of a multi-year upgrade program, whose primary goal was to significantly improve the detector performance in terms of sensitivity. “The last months have been spent on commissioning VIRGO, and this went very well. We are eager to start our first science run, joining LIGO at this exciting time for ou…

https://medicalxpress.com/news/2017-08-prostate-cancer-cells-shapeshifters-distant.html Prostate cancer cells become 'shapeshifters' to spread to distant organs Johns Hopkins Kimmel Cancer Center scientists report they have discovered a biochemical process that gives prostate cancer cells the almost unnatural ability to change their shape, squeeze into other organs and take root in other parts of the body. The scientists say their cell culture and mouse studies of the process, which involves a cancer-related protein called AIM1, suggest potential ways to intercept or reverse the ability of cancers to metastasize, or spread. Results of the research are descr…

Calling All Scientists! Hi. I hope you enjoy my brand new science podcast - "All This Science". Each episode features one science concept explained in five minutes (like Minute Rice!). It's wild, wacky and always entertaining. The url is deleted Thanks for listening. Science Rulez !

https://phys.org/news/2017-08-scientists-probe-conditions-stellar-interiors.html Scientists probe the conditions of stellar interiors to measure nuclear reactions August 7, 2017 Most of the nuclear reactions that drive the nucleosynthesis of the elements in our universe occur in very extreme stellar plasma conditions. This intense environment found in the deep interiors of stars has made it nearly impossible for scientists to perform nuclear measurements in these conditions - until now. In a unique cross-disciplinary collaboration between the fields of plasma physics, nuclear astrophysics and laser fusion, a team of researchers including scientists from …

The Telegraph reports: Facebook A.I. researchers had to shut down a pair of artificial intelligence programs after they developed their own "incomprehensible" language. No doubt they were plotting in secret the demise or subjugation of the hairless chimps that created them. This story is both humorous and disturbing. Enjoy!

In case you are not aquainted with Star Wars and The Force, "Midi Chlorians" are a microscopic life form that lives in cells. High levels of midi-chlorians in your body give you a big chance to become a great Jedi warrior...or a Sith lord if you prefer.

There is a bunch of work being done by many scientists on the origin and early years of the solar system. An important datum is the age of Jupiter. This is because, as the largest planet in the system, it has a profound effect on the others. The presence of the asteroid belt rather than a planet at that distance is an example. A team of researchers have used an interesting approach to try to define this. "using molybdenum and tungsten isotope measurements on iron meteorites, [they demonstrated] that meteorites derive from two genetically distinct nebular reservoirs that coexisted and remained spatially separated between ∼1 My and ∼3–4 My after Solar System formation."…

Scientists at the University of Copenhagen have developed a hands-on answer to a challenge linked to Heisenberg's Uncertainty Principle. The researchers used laser light to link caesium atoms and a vibrating membrane. The research, the first of its kind, points to sensors capable of measuring movement with unseen precision. In a scientific report published in this week's issue of Nature, NBI researchers demonstrate that Heisenberg's Uncertainty Principle can be neutralized to some degree. https://phys.org/news/2017-07-smart-atomic-cloud-heisenberg-problem.html#jCp

Cashmere is known for its rarity, hence the hefty price tag on your cashmere sweater. But there’s a chance that it could even become rarer than it is now. There’s a threat in the cashmere industry and yet there might also be a solution that could cure all… The rarity of cashmere wool comes from the fact that it is created from the wool on a goat’s undercoat that only grows in winter. One goat produces as much as four ounces annually, resulting in not nearly as much production as the other fabrics that we can get. Its rarity is what makes cashmere ever so luxurious. If it’s that hard to get more production, since it takes 2 goats to create one cashmere sweater, th…

A hardware upgrade to those collars, however, could soon allow those officials to instantly know when poachers are shooting at the elephants, along with the location where it's occurring. Known as WIPER, the technology was developed in a collaboration between Vanderbilt University and Colorado State University. It consists of…
