https://phys.org/news/2018-04-methane-greenhouse-effect-earth-surface.html First direct observations of methane's increasing greenhouse effect at the Earth's surface: Scientists have directly measured the increasing greenhouse effect of methane at the Earth's surface for the first time. A research team from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) tracked a rise in the warming effect of methane - one of the most important greenhouse gases for the Earth's atmosphere - over a 10-year period at a DOE field observation site in northern Oklahoma.

An Interesting article and paper this morning...... https://phys.org/news/2018-04-gravitational-lensing-sun-like-star-massive.html Gravitational lensing by sun-like star in massive cluster reveals blue supergiant 9 billion light years away: Thanks to a rare cosmic alignment, astronomers have captured the most distant normal star ever observed, some 9 billion light years from Earth. While astronomers routinely study galaxies much farther away, they're visible only because they glow with the brightness of billions of stars. And a supernova, often brighter than the galaxy in which it sits, also can be visible across the entire universe. Beyond a distanc…

https://www.techly.com.au/2018/03/21/nasa-just-found-way-fire-voyager-1s-thrusters-37-years-inactivity/ NASA just found a way to fire up Voyager 1’s thrusters after 37 years of inactivity After almost 40 years of inactivity, NASA engineers have managed to fire up the backup thrusters of the Voyager 1 spacecraft, the only human-made object in interstellar space. Voyager 1 was sent into space on September 5, 1977 to study the outer reaches of the Solar System as part of the Voyager program, and the sturdy craft still communicates with NASA to receive routine commands and return data. In fact, anyone can check out the most basic data it transmits in real …

https://phys.org/news/2018-03-reveals-startling-evidence-effects-climate.html New research led by U of T Mississauga geographer Igor Lehnherr provides startling evidence that remote areas in Canada's Arctic region—once thought to be beyond the reach of human impact—are responding rapidly to warming global temperatures. The study, published in Nature Communications, is the first to aggregate and analyze massive data sets on Lake Hazen, the world's largest lake by volume located north of the Arctic Circle. "Even in a place so far north, it's no longer cold enough to prevent the glaciers from shrinking," says Lehnherr, lead author on the study. "If this place …

https://phys.org/news/2018-03-scientists-results-neutrino-mountain.html Scientists report first results from neutrino mountain experiment March 27, 2018 by Jennifer Chu, Massachusetts Institute of Technology This week, an international team of physicists, including researchers at MIT, is reporting the first results from an underground experiment designed to answer one of physics' most fundamental questions: Why is our universe made mostly of matter? According to theory, the Big Bang should have produced equal amounts of matter and antimatter—the latter consisting of "antiparticles" that are essentially mirror images of matter, only bearing ch…

In Science Vosoughi et al published a paper showing that fake news on social media spread faster and wider than real news. This difference was not driven by bots, but by actual users. The spread of false news is also driven by network structure, but rather simply by the fact that most users seem to favour fake news. These findings, together with decreasing trust to mainstream media (Gallup: from 1998-2016, %great deal of trust: 59-> 51 democrats; 53->30 independents; 52->14 republicans), especially in the younger segment, highlight that it may become more difficult for folks to decide on what is fact or fiction.

DataAlign has been designed with you in mind. You wouldn't require any technical skiil or IT degree to use it. Simply, upload your data and the technology will do the rest, enabling you to focus on what really matters; your business. Despite the physical drive getting cheaper, there is always a need to back up your data online to ensure data redundancy. Having the data backed up on a cheap online data backup server will help you not only protect data but also keep it cost efficient. Online Cloud Backup There is always a risk attached when you store your data on physical disks like computer’s drive or an external drive. It is recommended to use online data backup as…

Yes according to François Hammer Et Al. it is very possible that Andromeda (as we know it) formed over a billion years after our own solar system did. A French and Chinese collaboration of scientists made deep observations between 2008 and 2014 and came up with a numerical model. They fed the model into some of the most powerful computers in France and got back a simulation that produces a galaxy that is a dead ringer for Andromeda. Their hypothesis is that between 7 and 10 billion years ago a much larger galaxy collided with a smaller one. The merger finally settled into the configuration we know (and love) between 1.8 and 3 billion years ago. https://www.obs…

Researchers have produced a "human scale" demonstration of a new phase of matter called quadrupole topological insulators that was recently predicted using theoretical physics. These are the first experimental findings to validate this theory. The researchers report their findings in the journal Nature. The team's work with QTIs was born out of the decade-old understanding of the properties of a class of materials called topological insulators. "TIs are electrical insulators on the inside and conductors along their boundaries, and may hold great potential for helping build low-power, robust computers and devices, all defined at the atomic scale," said mechanical…

https://apod.nasa.gov/apod/astropix.html The Hubble Ultra-Deep Field in Light and Sound Explanation: Have you heard about the Hubble Ultra-Deep Field? Either way, you've likely not heard about it like this -- please run your pointer over the featured image and listen! The Hubble Ultra-Deep Field(HUDF) was created in 2003-2004 with the Hubble Space Telescope staring for a long time toward near-empty space so that distant, faint galaxies would become visible. One of the most famous images in astronomy, the HUDF is featured here in a vibrant way -- with sonified distances. Pointing to a galaxy will play a note that indicates its approximate redshift. Because redsh…

http://www.citigroup.com/citi/news/2015/150218a.htm If it has to have $100Bn poured in then it is really sustainable? It is a bit like filling the car with a full tank of petrol and then claiming it is running without fuel...until the fuel runs out. That $100Bn represents energy being added to the 'sustainable' system. Energy produced by fossil fuels. If the system is running by itself after 10 years AND is able to produce a big enough surplus to provide for its replacement AND pay back the capital it absorbed then it counts as sustainable. Otherwise I cannot see how it qualifies.

http://joannenova.com.au/2018/03/giant-spanish-bank-spends-e100-b-on-earths-weather-cos-they-are-nice-people/ So what does "spending $100bn" mean? It means consuming $100Bn worth of energy, most of which has come from fossil fuels. Spending money = Consuming energy.

https://phys.org/news/2018-03-species-ravens-nevermore-evidence-speciation.html Two species of ravens nevermore? New research finds evidence of 'speciation reversal' For over a century, speciation—where one species splits into two—has been a central focus of evolutionary research. But a new study almost 20 years in the making suggests "speciation reversal"—where two distinct lineages hybridize and eventually merge into one—can also be extremely important. The paper, appearing March 2 in Nature Communications, provides some of the strongest evidence yet of the phenomenon, in two lineages of Common Ravens."The bottom line is [speciation reversal] is a natural evol…

Ipsos have carried out a survey of what people perceive about the world, versus how it is. In general, particularly when it comes to crime and terrorism, people think things are much worse than they are. The ideas about alcohol consumption by country are quite amusing: stereotypical and generally wrong (you will probably be surprised by the country with the highest alcohol consumption). https://perils.ipsos.com/slides/ And, perhaps not surprisingly, the countries where people are most confident about their answers are also the countries where they are most wrong.
