Earth’s oceans have absorbed 60 percent more heat than previously thought
Princeton and Scripps researchers report that the world’s oceans absorbed more than 13 zettajoules — which is a joule, the standard unit of energy, followed by 21 zeroes — of heat energy each year between 1991 and 2016. That’s 150 times more heat energy each year than the energy humans produce as electricity annually. The estimate is 60 percent higher than that used in the IPCC’s Fifth Assessment Report…

Earth’s oceans have absorbed 60 percent more heat than previously thought

For each year during the past quarter century, the world’s oceans have absorbed an amount of heat energy that is 150 times the energy humans produce as electricity annually, according to a study led by researchers at Princeton and the Scripps Institution of Oceanography at the University of California-San Diego. The strong ocean warming the researchers found suggests that Earth is more sensitive to fossil-fuel emissions than previously thought.

Danish physicists claim to cast doubt on detection of gravitational waves
The Nobel Prize-winning first direct detection of gravitational waves announced in 2016 is being called into question. LIGO responds: “There is absolutely no validity to their claims.”. The first direct detection of gravitational waves was announced on February 11, 2016, spawned headlines around the world, snagged the 2017 Nobel Prize in Physics, and officially launched a new era of so-called “multi-messenger” astronomy. But a team of physicists at the Niels Bohr Institute in Copenhagen, Denmark, is calling that detection into question based on its own independent data analysis conducted over the last two and a half years…

All the planets found by NASA’s Kepler space telescope – Spoiler: There was a lot of them.
Earlier this week, NASA’s Kepler space telescope ran out of fuel and retired from its goal of discovering a tremendous number of planets and systems out in space. Very sad, enjoy your retirement in the great void Mr. Kepler. Launched in 2009, Kepler literally transformed our view of what lay out there in space, confirming suspicions that space is jam-packed with planets very similar to Earth. It’s a terrifying yet inspiring thought…

Changing Up Your Linux Distro
It’s common for Linux users to hop between distributions and survey the field, and I recently reached a point where I had to seriously rethink the one I was using most of the time. Between hardware compatibility issues with my old standby and some discouraging missteps with other go-to choices, I felt the time had come to reassess my pool of preferred distributions and repopulate it from scratch…

Disaster Avoidance: How Visibility Could Save The Day
It’s much better to be prepared in advance than to have to deal with recovering from a disaster. Unplanned downtime in a data center is a disaster. In 2016, the average cost for unplanned downtime was $8,850 per minute. With an average downtime of 95 minutes, there is potential for a significant impact on the business and the bottom line. To prevent this kind of downtime, businesses need to protect themselves as much as possible from threats to data center operations…

iPad Pro Benchmark Scores Revealed – Shows the Tablet Is Nearly as Fast as a 15-Inch MacBook Pro With a 6-Core CPU
During the iPad Pro announcement, Apple showcased the performance of its A12X Bionic chipset, which is made using TSMC’s 7nm FinFET architecture. The SoC is the first from the company to feature an octa-core processor. The tech giant also went on to say that it can deliver the performance of an Xbox One and in a package that is 94 percent smaller. Now, the latest string of benchmarks for the iPad Pro has come forth, revealing that Apple’s latest tablets are nearly as fast as a 2018 15-inch MacBook Pro. In case you didn’t know, the latest iteration of the company’s 15-inch notebooks feature a 6-core CPU, with the decked out version sporting a Core i9 chip…

Astronomers spot signs of supermassive black hole mergers
Jets from double black holes change direction continuously. The effect can explain features in this 5 GHz radio map of 3C 334 and many powerful radio sources in the sky. The jet emanates from the nucleus of a galaxy (its stars are not visible at radio frequencies) about 10 billion light years from our own. The image spans five million light years from left to right. The peculiar structure of the jets signifies a periodic change of the direction of the jet (precession), an effect that is predicted for jets from black hole pairs. The inset diagram schematically illustrates the physical processes in the black hole pair. Jets may form in gas discs around black holes. The direction of the jets is tied to the spin of the black hole. The spin axis is shown as a red arrow. The latter changes direction periodically due to the presence of the second black hole…

Astronomers spot signs of supermassive black hole mergers

New research, published today in the journal Monthly Notices of the Royal Astronomical Society, has found evidence for a large number of double supermassive black holes, likely precursors of gigantic black hole merging events. This confirms the current understanding of cosmological evolution—that galaxies and their associated black holes merge over time, forming bigger and bigger galaxies and black holes.

Astronomers confirm collision between two Milky Way satellite galaxies
If you’re standing in the Southern Hemisphere on a clear night, you can see two luminous clouds offset from the Milky Way. These clouds of stars are satellite galaxies of the Milky Way, called the Small Magellanic Cloud and the Large Magellanic Cloud, or SMC and LMC. Using the newly released data from a new, powerful space telescope, University of Michigan astronomers have discovered that the southeast region, or “Wing,” of the Small Magellanic Cloud is moving away from the main body of that dwarf galaxy, providing the first unambiguous evidence that the Small and Large Magellanic Clouds recently collided…

The Quiz on CPU 0: Playing Scheduler Wars with AMD’s Threadripper 2990WX
One of the telling conclusions from our original 32-core AMD Ryzen Threadripper 2990WX review was that because of the arrangement of cores and memory, performance in most applications did not scale from the 16-core, and in some cases regressed. Due to a series of discussions, one potential culprit could be the fact that Windows scheduler seems to prioritize CPU 0 over everything else. We did some testing…

8-Way Linux Distribution Benchmarks On The Intel Core i9 9900K – One Distro Wins 67% Of The Time
Following last week’s release of the Intel Core i9 9900K, I spent several days testing various Linux distributions on this latest Core i9 CPU paired with the new ASUS Z390-A PRIME motherboard. I was testing not only to see that all of the Linux distributions were playing fine with this latest and greatest desktop hardware but also how the performance was looking. Benchmarked this round on the i9-9900K was Ubuntu 18.04.1 LTS, Ubuntu 18.10, Clear Linux 25720, Debian Buster Testing, Manjaro 18.0-RC3, Fedora Workstation 29, openSUSE Tumbleweed, and CentOS 7…
