Feeding Seaweed To Cows Eliminates Methane Emissions

Dave Knott writes: A Canadian farmer has “helped lead to a researcher’s discovery of an unlikely weapon in the battle against global warming: a seaweed that nearly eliminates the destructive methane content of cow burps and farts, ” reports the CBC. “Joe Dorgan began feeding his cattle seaweed from nearby beaches more than a decade ago as a way to cut costs… Then researcher Rob Kinley of Dalhousie University caught wind of it.” He tested Dorgan’s seaweed mix, discovering that it reduced the methane in the cows’ burps and farts by about 20 per cent. “Kinley knew he was on to something, so he did further testing with 30 to 40 other seaweeds. That led him to a red seaweed Asparagopsis taxiformis he says reduces methane in cows burps and farts to almost nothing.” “Ruminant animals are responsible for roughly 20% of greenhouse gas emissions globally, so it’s not a small number, ” said Kinley, an agricultural research scientist now working at the Commonwealth Scientific and Industrial Research Organisation in Queensland, Australia. “We’re talking numbers equivalent to hundreds of millions of cars.” The researcher predicts a seaweed-based cow feed could be on the market within three to five years, according to the article. “He says the biggest challenge will be growing enough seaweed.” Read more of this story at Slashdot.

Scientists Discover Antibody That Neutralizes 98% of HIV Strains

An anonymous reader quotes a report from The Inquisitr: The National Institute of Allergy and Infectious Diseases (NIAID) announced this week that a “remarkable” breakthrough has been made in the study of preventing and treating the human immunodeficiency virus (HIV), the virus that leads to acquired immunodeficiency syndrome (AIDS), according to a press release posted on the agency’s official website. The breakthrough centers around the discovery of a powerful antibody named N6 that is highly effective in both binding to the surface of the HIV virus and neutralizing it. The former has proved elusive in the past. “Identifying broadly neutralizing antibodies against HIV has been difficult because the virus rapidly changes its surface proteins to evade recognition by the immune system, ” the press release explains. The antibody was initially discovered in an HIV-positive person and has since proven to potentially neutralize 98 percent of HIV isolates, “including 16 of 20 strains resistant to other antibodies of the same class, ” according to the press release. Researchers have had previous success with other antibodies, but N6 appears to be more effective. The new discovery has potential benefits far beyond preventing and treating HIV as well. Studying exactly how N6 works could potentially lead to breakthroughs in other anti-viral antibodies. “Findings from the current study showed that N6 evolved a unique mode of binding that depends less on a variable area of the HIV envelope known as the V5 region and focuses more on conserved regions, which change relatively little among HIV strains, ” NIAID explains. “This allows N6 to tolerate changes in the HIV envelope, including the attachment of sugars in the V5 region, a major mechanism by which HIV develops resistance to other VRC01-class antibodies. Due to its potency, N6 may offer stronger and more durable prevention and treatment benefits, and researchers may be able to administer it subcutaneously (into the fat under the skin) rather than intravenously. In addition, its ability to neutralize nearly all HIV strains would be advantageous for both prevention and treatment strategies.” Read more of this story at Slashdot.

Final NASA Eagleworks Paper Confirms Promising EM Drive Results

An anonymous reader quotes a report from Hacked: Earlier this month Hacked reported that a draft version of the much expected EmDrive paper by the NASA Eagleworks team, had been leaked. Now, the final version of the paper has been published. The NASA Eagleworks paper, titled “Measurement of Impulsive Thrust from a Closed Radio-Frequency Cavity in Vacuum, ” has been published online as an open access “article in advance” in the American Institute of Aeronautics and Astronautics (AIAA)’s Journal of Propulsion and Power, a prestigious peer-reviewed journal. The paper will appear in the December print issue of the journal. The final version of the paper is very similar to the leaked draft. In particular, the NASA scientists confirm the promising experimental results: “Thrust data from forward, reverse, and null suggested that the system was consistently performing at 1.2 +/- 0.1 mNkW, which was very close to the average impulsive performance measured in air. A number of error sources were considered and discussed.” The scientists add that, though the test campaign was not focused on optimizing performance and was more an exercise in existence proof, it is still useful to put the observed thrust-to-power figure of 1.2 mN/kW in context. “[For] missions with very large delta-v requirements, having a propellant consumption rate of zero could offset the higher power requirements. The 1.2 mN/kW performance parameter is over two orders of magnitude higher than other forms of ‘zero propellant’ propulsion, such as light sails, laser propulsion, and photon rockets having thrust-to-power levels in the 3.33–6.67 uN/kW (or 0.0033–0.0067 mN/kW) range.” In other words, a modest thrust without having to carry fuel can be better, especially for long-distance space missions, than a higher thrust at the cost of having to carry bulky and heavy propellant reserves, and the EmDrive performs much better than the other “zero propellant” propulsion systems studied to date.

Police Raid Pirate Site, Seize 60 Servers Following MPAA Complaint

An anonymous reader quotes a report from TorrentFreak: When it comes to shutting down pirate sites, few groups have a longer history than the Motion Picture Association of America. The Hollywood organization has dozens of pirate scalps under its belt and today is able to claim another. Serving more than a million users every day, FS.to was one of Ukraine’s largest pirate sites. Ranked the country’s 21st most popular site overall, the movie-focused platform attracted the attention of the MPAA and local rights holders alike. That has resulted in one of the biggest raids ever seen in the country. According to the cyber crime division of Ukraine’s national police, an operation shut down the platform Monday following a complaint from Hollywood. The authorities say that 19 people suspected of running the site via a network of local and offshore companies were arrested. The operation to shut the site appears to have been significant. Raids took place at the offices and homes of the suspects, plus datacenters where equipment running the site was installed. Thus far around 60 servers have been seized from a range of local ISPs but the operation is still ongoing so the tally could increase. Local sources indicate that the authorities have linked local Internet company Ferazko Holding Inc. with FS since it owns several of the site’s domains including FS.to, BRB.to and FS.ua.

Microsoft Says Windows 10 Version 1607 is The Most Secure Windows Ever

A new white paper from Microsoft claims that “devices running Windows 10 are 58% less likely to encounter ransomware than when running Windows 7”. But an anonymous reader brings more news from Windows-watcher Paul Thurrott: in a separate blog post, it also makes its case for why Windows 10 version 1607 — that is, Windows 10 with the Anniversary Update installed — is the most secure Windows version yet. Improvements in this release include: Microsoft Edge runs Adobe Flash Player in an isolated container, and Edge exploits cannot execute other applications… [And] the Windows Defender signature delivery channel works faster than before so that the in-box anti-virus and anti-malware solution can help block ransomware, both in the cloud and on the client. Additionally, Windows Defender responds to new threats faster using improved cloud protection and automatic sample submission features, plus improved behavioral heuristics aimed at detecting ransomware-related activities. Interestingly, the paper also touts Microsoft’s “Advancing machine-learning systems in our email services to help stop the spread of ransomware via email delivery.” Read more of this story at Slashdot.

Hack Exposes 412 Million Accounts on AdultFriendFinder Sites

“Almost every account password was cracked, thanks to the company’s poor security practices, ” reports ZDNet — even for “deleted” accounts. An anonymous reader quotes their article: The hack includes 339 million accounts from AdultFriendFinder.com, which the company describes as the “world’s largest sex and swinger community [and] also includes over 15 million “deleted” accounts that weren’t purged from the databases. On top of that, 62 million accounts from Cams.com, and 7 million from Penthouse.com were stolen, as well as a few million from other smaller properties owned by the company. The data accounts for two decades’ worth of data from the company’s largest sites, according to breach notification LeakedSource, which obtained the data… The three largest site’s SQL databases included usernames, email addresses, and the date of the last visit, and passwords, which were either stored in plaintext or scrambled with the SHA-1 hash function, which by modern standards isn’t cryptographically as secure as newer algorithms. The attack apparently coincides with the discovery of “a local file inclusion flaw on the AdultFriendFinder site, which if successfully exploited could allow an attacker to remotely run malicious code on the web server. ” Ironically, Friend Finder Networks doesn’t even own Penthouse.com anymore. They sold the site to a new owner last February. Read more of this story at Slashdot.

Alibaba Posts $1 Billion in Sales in 5 Minutes on Singles’ Day

Alibaba Group posted $1 billion (6.81 billion yuan) of sales within the first five minutes of its Singles’ Day sales, a 24-hour event that may offer clues on the health of the Chinese economy and its largest online retailer. From a report on Bloomberg:Investors are keeping a close eye on the annual Nov. 11 spending blitz that dwarfs Black Friday and Cyber Monday in the U.S., to see if Alibaba can reprise the 60 percent leap in transactions to 91.2 billion yuan it managed last year. The e-commerce giant again turned up the star-wattage for 2016, enlisting Hollywood actress Scarlett Johansson, sports celebrity David Beckham, basketball legend Kobe Bryant and pop-rock band One Republic to headline a pre-sale gala and drum up international attention. Pioneered by Alibaba in 2009 and since replicated by rivals including JD.com Inc., Singles’ Day has become somewhat of a barometer of Chinese consumer sentiment. Read more of this story at Slashdot.

Pandora’s new website points to an on-demand future

Pandora has generated a lot of buzz about its rumored on-demand platform based on Rdio, and is working on an extensive re-branding ahead of that. It recently unveiled a new logo , and today launched a completely revamped website. As part of the new changes, you’ll now see radio stations in a grid of album art instead of an ordered list, much like with Google Play Music . The control bar with thumbs up/thumbs down, play, pause and song information has moved from the top of the screen to the very bottom now as well. The design makes lets you navigate “between past, present and future listening, ” Pandora says, making it easier to create and organize stations. Interestingly, Pandora cribbed from Spotify and is offering tour dates on both the Now Playing and artist profile pages. Finally, you’ll be able to replay and skip tracks, provided you’re willing to watch a video commercial, while subscribers to the $5 Pandora Plus option will be able to do it ad-free. There are no options to stream songs on demand, but that will likely change soon. Pandora will reportedly launch a $10 on-demand service like Spotify or Apple Music based on the technology it purchased from bankrupt Rdio. When it arrives, Pandora plans to expand to new countries and has ambitions to triple its subscriber base to 11 million by 2020. Despite having 78 million monthly listeners and 3.9 million subscribers, the company lost $170 million last year. Given all that, it no doubt wants a strong launch for its on-demand site, starting with the new logo and website refresh.

First Color Images Produced By an Electron Microscope

Slashdot reader sciencehabit quotes Science magazine: Imagine spending your whole life seeing the world in black and white, and then seeing a vase of roses in full color for the first time. That’s kind of what it was like for the scientists who have taken the first multicolor images of cells using an electron microscope. Electron microscopes can magnify an object up to 10 million times, allowing researchers to peer into the inner workings of, say, a cell or a fly’s eye, but until now they’ve only been able to see in black and white. The new advance — 15 years in the making — uses three different kinds of rare earth metals called lanthanides…layered one-by-one over cells on a microscope slide. The microscope detects when each metal loses electrons and records each unique loss as an artificial color. Read more of this story at Slashdot.

A New Process Turns Sewage Into Crude Oil

Big Hairy Ian shares this report from New Atlas: The U.S. Department of Energy’s Pacific Northwest National Laboratory has found a way to potentially produce 30 million barrels of biocrude oil per year from the 34 billion gallons of raw sewage that Americans create every day… [T]he raw sewage is placed in a reactor that’s basically a tube pressurized to 3, 000 pounds per square inch and heated to 660 degrees Fahrenheit, which mimics the same geological process that turned prehistoric organic matter into crude oil by breaking it down into simple compounds, only…it takes minutes instead of epochs… The end product is very similar to fossil crude oil with a bit of oxygen and water mixed in and can be refined like crude oil using conventional fractionating plants. After six years of development, they’ve licensed the process for a $6 million pilot plant that’s expected to launch in 2018. Read more of this story at Slashdot.
