On December 7, a Magic: The Gathering player with a YouTube channel called "UnSleevedMedia" ( https://www.youtube.com/user/mtgheadquarters ) was banned for life from the game by the Hasbro subsidiary Wizards of the Coast for allegedly harassing others in the MtG community on social media. As a consequence, he immediately lost access to all the virtual items he's previously purchased while receiving no refund, and he may no longer play online, partake in tournaments, or cover events on his YouTube channel (details: https://www.youtube.com/watch?v=NIh3ykLBzOM ).
The ban was issued after articles appeared on gaming news sites Polygon ( https://www.polygon.com/2017/11/29/16709796/magic-the-gathering-cosplayer-harassment-youtube ) and Kotaku ( https://www.kotaku.com.au/2017/11/magic-subreddit-on-lockdown-after-cosplayer-quit-due-to-alleged-harassment/ ), where a cosplayer accused UnsleevedMedia operator Jeremy Hambly of persistent harassment. (Note: While the articles report on the controversy, neither present any actual evidence for either side.)
While Mr Hambly claims that the allegations of threats and harassment are demonstrably false, and that the evidence against him is based on excerpts from Twitter/Facebook posts taken out of context, he now says he's uncovered something quite chilling while investigating the case: evidence that employees at Wizards of the Coast are trawling the Internet looking for social media activities going back years in search of conduct they might find "objectionable".
In at least one instance they've allegedly requested and gained access to a closed Facebook group only tangentially related to the MtG community, and then issued bans and warnings based on the contents of conversations therein. This includes a one-year ban against professional player Travis Woo, who has now effectively lost his job. Mr Hambly presented the evidence for these claims in a YouTube video ( https://www.youtube.com/watch?v=UGFcLvDRJNQ ) on his other channel, "The Quartering" ( https://www.youtube.com/channel/UCfwE_ODI1YTbdjkzuSi1Nag ).
In response to this, he has started a change.org petition ( https://www.change.org/p/hasbro-wizards-of-the-coast-must-reinstate-travis-woo-jeremy-hambly ) asking people to boycott all Hasbro products until such time as the bans are reversed. His main argument is that corporations should not be allowed enforce End User License Agreements that dictate what a person may or may not say or do in their spare time on social media.
(Disclaimer: I've signed the petition, as I wouldn't like to see a future where a Twitter spat could cost someone their Steam games.)
Excitonium, a strange form of matter that was first theorized almost 50 years ago, has now been discovered by researchers. What is excitonium? It is a rather exotic condensate that exhibits macroscopic quantum phenomena like a superconductor or a superfluid. It consists of excitons, particles formed from an unlikely pairing of an escaped electron and the hole it leaves behind. The hole actually behaves like a positively-charged particle itself. It attracts an electron and together they form the composite particle known as the exciton.
In their experiments on non-doped crystals of the transition metal dichalcogenide titanium diselenide (1T-TiSe2), the researchers were able to observe the material and its precursor soft plasmon phase, called "the smoking gun" that proves excitonium's existence. The precursor phase emerges as the material approaches its critical temperature. The scientists reproduced their results 5 times on different cleaved crystals during the testing, adding more confidence to the study.
What they achieved in particular is developing a new technique called momentum-resolved electron energy-loss spectroscopy (M-EELS) that is sensitive enough to distinguish the new material from Peierls phase, an unrelated substance that has the same symmetry.
An exciton is a bound state of an electron and an electron hole which are attracted to each other by the electrostatic Coulomb force. It is an electrically neutral quasiparticle that exists in insulators, semiconductors and in some liquids. The exciton is regarded as an elementary excitation of condensed matter that can transport energy without transporting net electric charge.
[...] Provided the interaction is attractive, an exciton can bind with other excitons to form a biexciton, analogous to a dihydrogen molecule. If a large density of excitons is created in a material, they can interact with one another to form an electron-hole liquid, a state observed in k-space indirect semiconductors.
Additionally, excitons are integer-spin particles obeying Bose statistics in the low-density limit. In some systems, where the interactions are repulsive, a Bose–Einstein condensed state, called excitonium, is predicted to be the ground state. Some evidence of excitonium has existed since the 1970s, but has often been difficult to discern from a Peierls phase. Exciton condensates have allegedly been seen in a double quantum well systems. In 2017 Kogar et al. found "compelling evidence" for observed excitons condensing in the three-dimensional semimetal 1T-TiSe2.

It was about a year ago that Boeing Chief Executive Dennis Muilenburg first began saying his company would beat SpaceX to Mars. "I'm convinced that the first person to step foot on Mars will arrive there riding on a Boeing rocket," he said during a Boeing-sponsored tech summit in Chicago in October 2016.
On Thursday, Muilenburg repeated that claim on CNBC. Moreover, he added this tidbit about the Space Launch System rocket—for which Boeing is the prime contractor of the core stage—"We're going to take a first test flight in 2019 and we're going to do a slingshot mission around the Moon."
Unlike last year, Muilenburg drew a response from SpaceX this time. The company's founder, Elon Musk, offered a pithy response on Twitter: "Do it."
The truth is that Boeing's rocket isn't going anywhere particularly fast. Although Muilenburg says it will launch in 2019, NASA has all but admitted that will not happen. The rocket's maiden launch has already slipped from late 2017 into "no earlier than" December 2019. However, NASA officials have said a 2019 launch is a "best case" scenario, and a slip to June 2020 is more likely.
Also, the next SpaceX flight is an ISS resupply mission and is scheduled for this coming Tuesday (December 12, 2017) at 1646 GMT (11:46 a.m. EST) from SLC-40, Cape Canaveral Air Force Station, Florida. The plan is for the booster to return to landing at Landing Zone-1, also at Cape Canaveral.

Private emails between scientists working on a controversial genetic technology called "gene drive" were released last week. Obtained through a Freedom of Information Act (FOIA) request, their publication has been criticized by some as an attempt to discredit the science community.
[...] The emails themselves, however, are news, and they were obtained in a lawful, straightforward way and were reported on by respected traditional news sources, such as The Guardian, which gave proper context to the files.
The release of these emails by [biosafety consultant Edward Hammond] who has a clear point-of-view on the issue, however, has led to yet another discussion of the proper way of publishing raw documents. Nature, one of the more respected and widely read science publishers, mentions the release of these emails in the same breath as emails that were obtained by illegal hacking in an editorial published this week:
The release of the e-mails echoes the way in which hackers released documents stolen from climate scientists before a major UN meeting in 2009. Much commentary on those documents suggested—wrongly—that scientists were up to no good. Still, damage was done and public trust in scientists declined. It would be unfortunate if the trick were repeated here, not least because it is scientists working on gene drives who have raised many of the concerns.
The 2009 hack that Nature mentions was terrible for scientists—climate scientists, in particular. When an email server at University of East Anglia's Climatic Research Unit was breached, as part of a climate change denier campaign, emails were dishonestly misrepresented to suggest a conspiracy was afoot.
It is reasonable and fair game for Nature to take issue with the way Hammond framed the documents, but juxtaposing the use of FOIA—a crucial process by which citizens hold their governments accountable—alongside a major incident of criminal hacking is bizarre, and was handled poorly.
If Nature meant to say that Hammond's FOIA trove was presented with malicious intent, then it failed to make that point clear.
"In our view, the editorial did not imply that FOIA—including the publishing of FOIA documents—is comparable to illegal hacking," Nature senior press manager Rebecca Walton told Motherboard.

One of Amazon's top-selling electronic gun safes contains a critical vulnerability that allows it to be opened by virtually anyone, even when they don't know the password.
The Vaultek VT20i handgun safe, ranked fourth in Amazon's gun safes and cabinets category, allows owners to electronically open the door using a Bluetooth-enabled smartphone app. The remote unlock feature is supposed to work only when someone knows the four- to eight-digit personal identification number used to lock the device. But it turns out that this PIN safeguard can be bypassed using a standard computer and a small amount of programming know-how.
As the video demonstration below shows, researchers with security firm Two Six Labs were able to open a VT20i safe in a matter of seconds by using their MacBook Pro to send specially designed Bluetooth data while it was in range. The feat required no knowledge of the unlock PIN or any advanced scanning of the vulnerable safe. The hack works reliably even when the PIN is changed. All that's required to make it work is that the safe have Bluetooth connectivity turned on.
[...] The vulnerability means that anyone who relies on a VT20i safe to secure valuables should immediately turn off Bluetooth connectivity and leave it off indefinitely. Safes can still be locked and unlocked using a traditional physical key, as well as by owners' fingerprints. Some Amazon customers, however, have complained the fingerprint feature is flawed as well.

Arthur T Knackerbracket has found the following story:
Algae are highly prized for their ability to make useful products, but a lack of engineering tools has hindered basic research and growth of the industry for decades, researchers say.
Scientists at the University of Edinburgh sought to improve the efficiency of gene-editing to increase yields of products currently made using algae, including some food supplements. The advance could also enable algae to make new products, such as medicines.
The technique uses molecules that act like scissors to cut DNA -- called CRISPR molecules -- which allow researchers to add new genes or modify existing ones. Until now, scientists have struggled to develop a technique that works efficiently in algae.
To overcome this, the team added CRISPR molecular scissors and short pieces of DNA directly to algae cells to make precise modifications to the genetic code.
Their new method is more specific and increases efficiency 500-fold compared to previous techniques. The discovery could unleash the potential of the global algae industry, projected to be worth $1.1billion by 2024.
[...] Dr Attila Molnar, of the University of Edinburgh's School of Biological Sciences, who led the study, said: "Our findings mark a key advance in large-scale algal genome engineering. Our technique is applicable to a wide range of species, and could pave the way for the development of designer algae, which has many biotechnology applications."

When Mark DePristo and Ryan Poplin began their work, Google's artificial intelligence did not know anything about genetics. In fact, it was a neural network created for image recognition—as in the neural network that identifies cats and dogs in photos uploaded to Google. It had a lot to learn.
But just eight months later, the neural network received top marks at an FDA contest for accurately identifying mutations in DNA sequences. And in just a year, the AI was outperforming a standard human-coded algorithm called GATK. DePristo and Poplin would know; they were on the team that originally created GATK.
It had taken that team of 10 scientists five years to create GATK. It took Google's AI just one to best it. "It wasn't even clear it was possible to do better," says DePristo. They had thrown every possible idea at GATK. "We built tons of different models. Nothing really moved the needle at all," he says. Then artificial intelligence came along.
This week, Google is releasing the latest version of the technology as DeepVariant. Outside researchers can use DeepVariant and even tinker with its code, which the company has published as open-source software.
DeepVariant, like GATK before it, solves a technical but important problem called "variant calling." When modern sequencers analyze DNA, they don't return one long strand. Rather, they return short snippets maybe 100 letters long that overlap with each other. These snippets are aligned and compared against a reference genome whose sequence is already known. Where the snippets differ with the reference genome, you probably have a real mutation. Where the snippets differ with the reference genome and with each other, you have a problem.
"The Defense Department is starting the first agency-wide financial audit in its history," the Pentagon's news service says, announcing that it's undertaking an immense task that has been sought, promised and delayed for years.
Of the tally that is starting this week, chief Pentagon spokesperson Dana W. White said, "It demonstrates our commitment to fiscal responsibility and maximizing the value of every taxpayer dollar that is entrusted to us."
"Beginning in 2018, our audits will occur annually, with reports issued Nov. 15," the Defense Department's comptroller, David L. Norquist, said.
The Defense Department has famously never been audited, despite receiving hundreds of billions of dollars annually and having more than $2.2 trillion in assets.
The Iron Age began in Anatolia and the Caucasus around 1200 BCE. But nearly 2,000 years earlier, various cultures were already fashioning objects out of iron. These items were extremely rare and always greatly treasured. Iron ore abounds on the Earth's surface. So what made these artifacts so valuable? Initial research had shown that some were made with iron from meteorites, which led scientists to wonder how many others were. Albert Jambon gathered the available data and conducted his own nondestructive chemical analyses of samples using a portable X-ray fluorescence spectrometer. His collection of iron artifacts includes beads from Gerzeh (Egypt, −3200 BCE); a dagger from Alaca Höyük (Turkey, −2500 BCE); a pendant from Umm el-Marra (Syria, −2300 BCE); an axe from Ugarit (Syria, −1400 BCE) and several others from the Shang dynasty civilization (China, −1400 BCE); and the dagger, bracelet, and headrest of Tutankhamen (Egypt, −1350 BCE).

Google's R&D arm, Google Research, recently dedicated some time and resources to discovering ways to improve the performance of foveated rendering. Foveated rendering already promises vast performance improvements compared to full-resolution rendering. However, Google believes that it can do even better. The company identified three elements that could be improved, and it proposed three solutions that could potentially solve the problems, including two new foveation techniques and a reworked rendering pipeline.
Foveated rendering is a virtual reality technique that uses eye tracking to reduce the amount of image quality necessary in areas covered by the peripheral vision.
The new techniques mentioned are Phase-Aligned Rendering and Conformal Rendering.

Women who rely on birth control pills or contraceptive devices that release hormones face a small but significant increase in the risk for breast cancer, according to a large study published on Wednesday.
The study [DOI: 10.1056/NEJMoa1700732] [DX], which followed 1.8 million Danish women for more than a decade, upends widely held assumptions about modern contraceptives for younger generations of women. Many women have believed that newer hormonal contraceptives are much safer than those taken by their mothers or grandmothers, which had higher doses of estrogen.
The new paper estimated that for every 100,000 women, hormone contraceptive use causes an additional 13 breast cancer cases a year. That is, for every 100,000 women using hormonal birth control, there are 68 cases of breast cancer annually, compared with 55 cases a year among nonusers.
While a link had been established between birth control pills and breast cancer years ago, this study is the first to examine the risks associated with current formulations of birth control pills and devices in a large population.
The study found few differences in risk between the formulations; women cannot protect themselves by turning to implants or intrauterine devices that release a hormone directly into the uterus.
The research also suggests that the hormone progestin — widely used in today's birth control methods — may be raising breast cancer risk.

"ZHANG denies downloading the movie but Defendant's current motion for summary judgment challenges a different portion of F&D's case: Defendant argues that F&D has alienated all of the relevant rights necessary to sue for infringement under the Copyright Act," Madden writes.
The filmmakers opposed the request and pointed out that they still had some rights. However, this is irrelevant according to the defense, since the distribution rights are not owned by them, but by a company that's not part of the lawsuit.
"Plaintiff claims, for example, that it still owns the right to exploit the movie on airlines and oceangoing vessels. That may or may not be true – Plaintiff has not submitted any evidence on the question – but ZHANG is not accused of showing the movie on an airplane or a cruise ship.
"He is accused of downloading it over the Internet, which is an infringement that affects only an exclusive right owned by non-party DISTRIBUTOR 2," Madden adds.

Google will take 30 days to gather feedback on 'responsible' uses of accessibility code before cracking down.
Almost a month ago, Google cracked down on developers that used Android's accessibility features for apps that weren't expressly created for people with disabilities. The company told developers that they had to show how their code actually helped those with a disability or face removal from the Play Store within 30 days. Now, however, Google is pausing that final solution for another month to consider "responsible and innovative uses of accessibility services."
[...] In the current email, Google asked recipients to send feedback around their appropriate use of the accessibility features in Android: "If you believe your app uses the Accessibility API for a responsible, innovative purpose that isn't related to accessibility, please respond to this email and tell us more about how your app benefits users. This kind of feedback may be helpful to us as we complete our evaluation of accessibility services."

Microsoft has posted an out-of-band security update to address a remote code execution flaw in its Malware Protection Engine.
Redmond says the flaw, dubbed CVE-2017-11937, has not yet been exploited in the wild. Because it is an out-of-band critical fix, however, it should be installed as soon as possible. For most users, this will happen automatically.
The security hole is present in Windows Defender and Microsoft Security Essentials, as well as Endpoint Protection, Forefront Endpoint Protection, and Exchange Server 2013 and 2016.
[...] According to Microsoft, the vulnerability can be triggered when the Malware Protection Engine scans a downloaded file to check for threats. In many systems this is set to happen automatically for all new files.
By exploiting a memory corruption error in the malware scanning tool, the attack file would be able to execute code on the target machine with LocalSystem privileges.
