Google Subsidiary in Russia To File for Bankruptcy (wsj.com) 53

The Russian subsidiary of Alphabet's Google plans to file for bankruptcy, saying it had become impossible for the company to pay employees and suppliers. From a report: Google submitted a notice of intent to declare itself bankrupt, according to a message published Wednesday on Russia's Fedresurs registry. A Google spokesperson separately said an earlier move by authorities to seize its bank account made continuing operations in the country impossible. "The Russian authorities' seizure of Google Russia's bank account has made it untenable for our Russia office to function, including employing and paying Russia-based employees, paying suppliers and vendors, and meeting other financial obligations," the Google spokesperson said. The company had already paused most of its commercial operations in Russia, including all advertising, after the country's communications censor accused the company's YouTube video service of spreading misinformation and stoking protests.

Contact Lens That Can Release Drug Could Be Used To Treat Glaucoma (theguardian.com) 12

An anonymous reader quotes a report from The Guardian: Researchers in China revealed they have developed a contact lens that can sense an increase in pressure within the eye and release an anti-glaucoma drug should the pressure exceed a certain level. Writing in the journal Nature Communications, the team describe how they created the device using an upper and lower lens, with a snowflake-shaped pressure sensor and wireless power transfer device sandwiched between them around the rim of the lenses. The arrangement appears to give the effect of the wearer having golden irises. However, the team say the design allows the necessary components to be included in the device without blocking the wearer's view or irritating the eye.

When the pressure inside the eye increases, the gap between the upper and lower lenses decreases. This is detected by the pressure sensor by means of a cantilever. The sensor then sends a signal to the wireless system which subsequently triggers the release of an anti-glaucoma drug, from a hydrogel attached to an electrode, and enables it to cross the cornea of the eye. The drug, brimonidine, acts to reduce the pressure within the eye. The study reveals that the contact lenses have so far been tested on pigs' eyes and on the eyes of living rabbits -- albeit with smaller-sized lenses -- although trials have yet to be carried out in humans. The researchers note the lenses are not only soft and minimally invasive but are also battery-free, adding that the approach could be expanded to help tackle other eye diseases.
"We can now imagine that a glaucoma sufferer wearing these contact lenses will not only receive real-time information about the pressures within the eye, since the contact lens has built-in wireless capacity and can easily communicate with an app on your smartphone, but also receive, for example, pressure-relieving drugs when needed," said Prof Zubair Ahmed from the Institute of Inflammation and Aging at the University of Birmingham. "The materials required to create such contact lenses are inexpensive and soon could be mass-produced," he added.

After 28 Flights, Is NASA's 'Ingenuity' Mars Helicopter Nearing the End of Its Life? (msn.com) 61

After traveling 300 miles on the underbelly of the Perseverance rover, the "Ingenuity" helicopter has made 28 different flights over the surface of Mars, reports the Washington Post, staying aloft for a total of nearly one hour, flying 4.3 miles with a maximum speed of 12.3 miles per hour and a top altitude of 39 feet. "It's traversed craters, taken photos of regions that would be hard to reach on the ground, and served as a surprisingly resilient scout that has adapted to the changing Martian atmosphere and survived its harsh dust storms and frigid nights.

"Now the engineers and scientists at NASA's Jet Propulsion Laboratory are worried that their four-pound, solar-powered drone on Mars, may be nearing the end of its life." Winter is setting in on Mars. The dust is kicking up, coating Ingenuity's solar panels and preventing it from fully charging its six lithium-ion batteries. This month, for the first time since it landed on Mars more than a year ago, Ingenuity missed a planned communications session with Perseverance, the Mars rover that it relies on to send data and receive commands from Earth. Will a dust-coated Ingenuity survive a Martian winter where temperatures routinely plunge below minus-100 degrees Fahrenheit? And if it doesn't, how should the world remember the little helicopter that cost $80 million to develop and more than five years to design and build? Those closest to the project say that as time winds down for Ingenuity, it's hard to overstate its achievements....

"We built it as an experiment," Lori Glaze, the director of NASA's planetary science division, told The Washington Post. "So it didn't necessarily have the flight-qualified parts that we use on the big missions like Perseverance." Some, such as components from smartphones, were even bought off-the-shelf, so "there were chances that they might not perform in the environment as we expected. And so there was a risk that it wasn't going to work.... What happened was, and this is really key, after Ingenuity performed so well on those first five flights, the science team from Perseverance came to us and said, 'You know what, we want this helicopter to keep operating to help us in our exploration and achieving our science goals,' " Glaze said.

So NASA decided to keep flying....

On April 29, it took its last flight to date, No. 28, a quarter-of-a-mile jaunt that lasted two-and-a-half minutes. Now NASA wonders if that will be the last one. The space agency thinks the helicopter's inability to fully charge its batteries caused the helicopter to enter a low-power state. When it went dormant, the helicopter's onboard clock reset, the way household clocks do after a power outage. So the next day, as the sun rose and began to charge the batteries, the helicopter was out of sync with the rover: "Essentially, when Ingenuity thought it was time to contact Perseverance, the rover's base station wasn't listening," NASA wrote.

Then NASA did something extraordinary: Mission controllers commanded Perseverance to spend almost all of May 5 listening for the helicopter.

Finally, little Ingenuity phoned home.

The radio link, NASA said, "was stable," the helicopter was healthy, and the battery was charging at 41 percent.

But, as NASA warned, "one radio communications session does not mean Ingenuity is out of the woods. The increased (light-reducing) dust in the air means charging the helicopter's batteries to a level that would allow important components (like the clock and heaters) to remain energized through the night presents a significant challenge."

Maybe Ingenuity will fly again. Maybe not.

"At this point, I can't tell you what's going to happen next," Glaze said. "We're still working on trying to find a way to fly it again. But Perseverance is the primary mission, so that we need to start setting our expectations appropriately."

For Ingenuity's "Wright Brothers moment" — when it flew for the first time on another planet — it was actually carrying a postage-sized bit of fabric from the Wright Brothers original 1903 aircraft.

New EU Rules Would Require Chat Apps To Scan Private Messages for Child Abuse (theverge.com) 204

The European Commission has proposed controversial new regulation that would require chat apps like WhatsApp and Facebook Messenger to selectively scan users' private messages for child sexual abuse material (CSAM) and "grooming" behavior. The proposal is similar to plans mooted by Apple last year but, say critics, much more invasive. From a report: After a draft of the regulation leaked earlier this week, privacy experts condemned it in the strongest terms. "This document is the most terrifying thing I've ever seen," tweeted cryptography professor Matthew Green. "It describes the most sophisticated mass surveillance machinery ever deployed outside of China and the USSR. Not an exaggeration." Jan Penfrat of digital advocacy group European Digital Rights (EDRi) echoed the concern, saying, "This looks like a shameful general #surveillance law entirely unfitting for any free democracy." (A comparison of the PDFs shows differences between the leaked draft and final proposal are cosmetic only.) The regulation would establish a number of new obligations for "online service providers" -- a broad category that includes app stores, hosting companies, and any provider of "interpersonal communications service."

Lawmakers Offer Bill To Regulate Volume of Commercials On Streaming Services (thehill.com) 103

Sen. Sheldon Whitehouse (D-R.I.) and Rep. Anna Eshoo (D-Calif.) on Tuesday introduced a bill to regulate the volume of commercials shown on streaming platforms. The Hill reports: The bill is known as the Commercial Advertisement Loudness Mitigation (CALM) Modernization Act. It would modernize policies regarding ads on streaming services, saying that "the volume of commercials on streaming services cannot be louder than regular programming," according to Eshoo. It would also ramp up the Federal Communications Commission's ability to investigate and enforce violations of the original CALM Act and require a study into its effectiveness.

Eshoo added that since she and Whitehouse created the original CALM Act, streaming service providers have "recreated the problem of loud ads because the old law doesn't apply to them." "Today, we're updating the legislation for the benefit of consumers who are tired of diving for the mute button at every commercial break," Eshoo added.

UK, US, and EU Officially Blame Russia For Cyberattack Targeting Viasat (sky.com) 24

An anonymous reader quotes a report from Sky News: The UK, US and EU have formally accused Russia of being behind a cyber attack targeting a satellite communications network used in Ukraine. Businesses and individuals using routers made by Viasat, an American business that provides broadband-speed satellite internet connections, were knocked offline just before tanks began to roll into the country.

"The cyberattack took place one hour before Russia's unprovoked and unjustified invasion of Ukraine on 24 February 2022, thus facilitating the military aggression," the EU said in its statement. "Although the primary target is believed to have been the Ukrainian military, other customers were affected, including personal and commercial internet users," the Foreign Office added. As a result of the attack 5,800 wind turbines in Germany were knocked offline as they depended upon Viasat routers for remote monitoring and control. The company said in total tens of thousands of its terminals were effectively destroyed and needed to be replaced.
UK Foreign Secretary Liz Truss said: "This is clear and shocking evidence of a deliberate and malicious attack by Russia against Ukraine which had significant consequences on ordinary people and businesses in Ukraine and across Europe. We will continue to call out Russia's malign behavior and unprovoked aggression across land, sea and cyberspace, and ensure it faces severe consequences."

The attack was described as "yet another example of Russia's continued pattern of irresponsible behavior in cyberspace, which also formed an integral part of its illegal and unjustified invasion of Ukraine," in the EU's statement.

"Such behavior is contrary to the expectations set by all UN member states, including the Russian Federation, of responsible state behavior and the intentions of states in cyberspace. Russia must stop this war and bring an end to the senseless human suffering immediately," the EU added.

Low-Wage Earners To Get High-Speed Internet For $30 in Biden Program (washingtonpost.com) 226

echo123 writes: Twenty Internet providers, including AT&T, Comcast and Verizon, have agreed to provide high-speed service at a steep discount to low-income consumers, the White House announced Monday, significantly expanding broadband access for millions of Americans. The plan, a feature of the $1 trillion infrastructure package passed by Congress last year, would cost qualifying households no more than $30 per month. The discounts plus existing federal Internet subsidies mean the government will cover the full cost of connectivity if consumers sign on with one of the 20 participating companies. The White House estimates the program will cover 48 million households, or 40 percent of the country.

The 100-megabit-per-second service is fast enough for a family to work from home, complete schoolwork, browse the Internet and stream high-definition movies and TV shows, the White House said. Households can qualify for the subsidies, called the Affordable Connectivity Program, if their income is at or below 200 percent of federal poverty guidelines, a member of the household participates in certain federal anti-poverty initiatives -- including Medicaid, Supplemental Nutrition Assistance Program, federal housing assistance, Pell Grant tuition assistance, or free or reduced-price school meals -- or if the household already qualifies for an Internet provider's low-income service program. Consumers can check whether they qualify for discounted service at getinternet.gov.

Judge Dismisses Trump Lawsuit Seeking To Lift Twitter Ban (cnbc.com) 81

A judge on Friday dismissed a lawsuit by former President Donald Trump seeking to lift his ban from Twitter. But San Francisco federal district court Judge James Donato left the door open for Trump and other plaintiffs to file an amended complaint against Twitter that is consistent with his written decision Friday to toss the lawsuit in its entirety. CNBC reports: The social media giant had banned Trump on Jan. 8, 2021, citing the risk of the incitement of further violence on the heels of the Capitol riot by a mob of supporters of the then-president two days earlier. Trump, the American Conservative Union, and five individuals had sued Twitter and its co-founder Jack Dorsey last year on behalf of themselves and a class of other Twitter users who had been booted from the app. [...] His suit alleged that Twitter violated the plaintiffs' First Amendment rights to free speech, arguing that the bans were due to pressure on the company by Democratic members of Congress.

But in his 17-page ruling, Donato wrote that Trump and the other plaintiffs "are not starting from a position of strength" with their First Amendment claim. The judge noted, citing federal case law, that, "Twitter is a private company, and "the First Amendment applies only to governmental abridgements of speech, and not to alleged abridgements by private companies.'" Donato rejected the notion that Twitter's ban of Trump and the others was attributable to the government's actions, which would be the only way to uphold the claim of a violation of the First Amendment. "Overall, the amended complaint does not plausibly allege that Twitter acted as a government entity when it closed plaintiffs' accounts," Donato wrote.

The suit also asked the judge to rule that the federal Communications Decency Act was unconstitutional. The CDA says online service providers such as Twitter cannot be held responsible for content posted by others. Donato dismissed that claim after finding that the plaintiffs did not have legal standing to challenge the CDA. The judge said the only way they could have such standing was to show that Twitter "would not have de-platformed the plaintiff" or others but for the legal immunity conferred by the CDA when it came to content. [...]
Shortly after Twitter announced that it has agreed to be acquired by Elon Musk, Trump told Fox News that he is "not going back to Twitter," adding: "I am not going on Twitter, I am going to stay on Truth. I hope Elon buys Twitter because he'll make improvements to it and he is a good man, but I am going to be staying on Truth."

Cable Giants, ISPs, Telcos End Legal Fight Against California's Net Neutrality Law (theregister.com) 14

An anonymous reader quotes a report from The Register: California Attorney General Rob Bonta on Wednesday welcomed the decision by a group of telecom and cable industry associations to abandon their legal challenge of the US state's net neutrality law SB822. "My office has fought for years to ensure that internet service providers can't interfere with or limit what Californians do online," said Bonta in a statement. "Now the case is finally over. Following multiple defeats in court, internet service providers have abandoned this effort to block enforcement of California's net neutrality law. With this victory, we've secured a free and open internet for California's 40 million residents once and for all."

In December 2017, then Federal Communications Commission (FCC) chair Ajit Pai tossed out the 2015 net neutrality rules put in place during the Obama administration, freeing broadband providers to block, throttle, and prioritize internet traffic, among other things -- all of which were disallowed under the 2015 rules. On September 30, 2018, then California Governor Jerry Brown signed into law Senate Bill 822 (SB822), which more or less restored those rules. That same day, the Justice Department under the Trump administration challenged the law, as subsequently did the broadband companies benefiting from what Pai at the time referred to as a "light-touch approach."

The Justice Department, under the Biden administration, ended its opposition to California's net neutrality law back in February, 2021. The industry plaintiffs continued fighting SB822 in court but faced a setback in January, 2022, when the US Court of Appeals for the Ninth Circuit refused to block the law's enforcement as litigation progressed. Now those groups -- ACA Connects (America's Communications Association), CTIA (The Wireless Association), NCTA (The Internet & Television Association), and USTelecom (The Broadband Association) -- have withdrawn too. The trade associations, with the agreement of Bonta, filed a joint stipulation of dismissal without prejudice [PDF], which ends the telco legal challenge but allows the claim to be refiled at some later date.

Frontier Lied About Internet Speeds and 'Ripped Off Customers', FTC Says (arstechnica.com) 22

The Federal Trade Commission today said it "has moved to stop Internet service provider Frontier Communications from lying to consumers and charging them for high-speed Internet speeds it fails to deliver." From a report: Frontier was sued by the FTC in May 2021, and on Thursday, it agreed to a settlement with the FTC and district attorneys in Los Angeles County and Riverside County who represented the people of California. Frontier must pay $8.5 million to California "for investigation and litigation costs" and another $250,000 that will be distributed to Frontier customers who were harmed by Frontier's alleged actions. Frontier must also make changes, such as letting customers cancel service at no charge and "discount[ing] the bills of California customers who have not been notified that they are receiving DSL service that is much slower than the highest advertised speed," the FTC said.

VPN Providers Threaten To Quit India Over New Data Law (wired.com) 26

VPN companies are squaring up for a fight with the Indian government over new rules designed to change how they operate in the country. Wired: On April 28, officials announced that virtual private network companies will be required to collect swathes of customer data -- and maintain it for five years or more -- under a new national directive. VPN providers have two months to accede to the rules and start collecting data. The justification from the country's Computer Emergency Response Team (CERT-In) is that it needs to be able to investigate potential cybercrime. But that doesn't wash with VPN providers, some of whom have said they may ignore the demands.

"This latest move by the Indian government to require VPN companies to hand over user personal data represents a worrying attempt to infringe on the digital rights of its citizens," says Harold Li, vice president of ExpressVPN. He adds that the company would never log user information or activity and that it will adjust its "operations and infrastructure to preserve this principle if and when necessary." Other VPN providers are also considering their options. Gytis Malinauskas, head of Surfshark's legal department, says the VPN provider couldn't currently comply with India's logging requirements because it uses RAM-only servers, which automatically overwrite user-related data. [...] ProtonVPN is similarly concerned, calling the move an erosion of civil liberties.

Quantum Computing Has White House Mulling Risks, Rewards (whitehouse.gov) 22

The White House released a memorandum Wednesday that outlines a national effort to promote leadership in quantum computing and calls for security advances to prepare for future cyberthreats from quantum computing before they arise. From a report: "Quantum information science -- we'll call it 'QIS,' for short -- is a rapidly emerging scientific discipline that combines our best understanding of the subatomic world -- quantum mechanics -- with our best understanding of information systems -- information theory -- to generate revolutionary technologies and insights," said a senior administration official during a background press call on Tuesday.

[...] The announcement goes on to note that quantum computers could be a problem for digital communications and security. Quantum research is thought to soon reach a point where a "cryptanalytically relevant quantum computer" is possible. These computers could jeopardize US communications, control systems of critical infrastructure and security protocols used for most internet-based financial transactions, according to the memorandum. "Current research shows that at some point in the not-too-distant future, when quantum information science matures and quantum computers are able reach a sufficient size and level of sophistication, they will be capable of breaking much of the cryptography that currently secures our digital communications," said the senior administration official.

Climate Sceptic Thinktank Received Funding From Fossil Fuel Interests (theguardian.com) 90

An influential thinktank that has led the backlash against the government's net zero policy has received funding from groups with oil and gas interests, according to tax documents seen by the Guardian and OpenDemocracy. From a report: Though the Global Warming Policy Foundation (GWPF) has always said it is independent of the fossil fuel industry, the revelations about its funding will raise questions over its campaigning. The thinktank has always refused to disclose its donors, but tax documents filed with US authorities reveal that one of its donors has $30m of shares in 22 companies working in coal, oil and gas. Over four years the GWPF's US arm, the American Friends of the GWPF, received more than $1m from US donors. The vast majority of this, $864,884, was channelled to the UK group, with some being held back for expenses.

Of the $1.8m the GWPF has received in charitable donations since 2017, about 45% has come from the US. It received $210,525 in 2018 and 2020 from the Sarah Scaife Foundation -- set up by the billionaire libertarian heir to an oil and banking dynasty. The US-based foundation has $30m-worth of shares in 22 energy companies including $9m in Exxon and $5.7m in Chevron, according to its financial filings. Between 2016 and 2020, the American Friends of the GWPF received $620,259 from the Donors Trust, which is funded by the Koch brothers, who inherited their father's oil empire and have spent hundreds of millions of dollars funding the climate denial movement. "It is disturbing that the Global Warming Policy Foundation is acting as a channel through which American ideological groups are trying to interfere in British democracy," said Bob Ward, policy and communications director at the LSE Grantham Research Institute on Climate Change and the Environment.

FAA Wants US Airlines To Retrofit, Replace Radio Altimeters (reuters.com) 71

The Federal Aviation Administration (FAA) will meet Wednesday with telecom and airline industry officials on a push to retrofit and ultimately replace some airplane radio altimeters that could face interference from C-Band 5G wireless service. Reuters reports: The altimeters give data on a plane's height above the ground and are crucial for bad-weather landings, but airline concerns about wireless interference from a planned 5G rollout led to disruptions at some U.S. airports earlier this year. The FAA wants to use the meeting to establish "an achievable timeframe to retrofit/replace radar altimeters in the U.S. fleet," according to a previously unreported letter from the FAA's top aviation safety official Chris Rocheleau reviewed by Reuters. It also asked aviation representatives "to offer options and commit to actions necessary to meet these objectives."

The planned three-and-a-half hour roundtable meeting will also include a discussion on prioritizing retrofits with antenna filters, which mitigate potential interference from 5G. Antenna filters are currently in production, officials said. A key question is how to determine which planes are most at risk of interference and should therefore get retrofitted first. The meeting will also look at what is set to happen after July 5 and outline "changes to U.S. national airspace operating environment as a result of future 5G C-band deployment in the coming months."

Mac Studio's M1 Ultra Chip Outperforms on Computational Fluid Dynamics Benchmarks (hrtapps.com) 63

Dr. Craig Hunter is a mechanical/aerospace engineer with over 25 years of experience in software development. And now Dixie_Flatline (Slashdot reader #5,077) describes Hunter's latest experiment: Craig Hunter has been running Computational Fluid Dynamics (CFD) benchmarks on Macs for years--he has results going back to 2010 with an Intel Xeon 5650, with the most recent being a 28-core Xeon W from 2019. He has this to say about why he thinks CFD benchmarks are a good test: "As shown above, we see a pretty typical trend where machines get less and less efficient as more and more cores join the computation. This happens because the computational work begins to saturate communications on the system as data and MPI instructions pass between the cores and memory, creating overhead. It's what makes parallel CFD computations such a great real world benchmark. Unlike simpler benchmarks that tend to make CPUs look good, the CFD benchmark stresses the entire system and shows us how things hold up as conditions become more and more challenging."

With just 6 cores, the Mac Studio's M1 Ultra surpasses the 2019 Xeon before literally going off the original chart. He had to double the x-axis just to fit the M1's performance in. Unsurprisingly, he seems impressed:

"We know from Apple's specs and marketing materials that the M1 Ultra has an extremely high 800 GB/sec memory bandwidth and an even faster 2.5 TB/sec interface between the two M1 Max chips that make up the M1 Ultra, and it shows in the CFD benchmark. This leads to a level of CPU performance scaling that I don't even see on supercomputers."

FBI Searched the Data of Millions of Americans Without Warrants (bloomberg.com) 35

An anonymous reader quotes a report from Bloomberg: The FBI searched emails, texts and other electronic communications of as many as 3.4 million U.S. residents without a warrant over a year, the nation's top spy chief said in a report. The "queries" were made between December 2020 and November 2021 by Federal Bureau of Investigation personnel as they looked for signs of threats and terrorists within electronic data legally collected under the Foreign Intelligence Surveillance Act, according to an annual transparency report issued Friday by the Office of the Director of National Intelligence. The surge came as the FBI made a push to stop hacking attacks.

The authority the FBI used in this case was under Section 702 of FISA, which is set to expire at the end of next year unless it's renewed by Congress. The report doesn't say the activity was illegal or even wrong. But the revelation could renew congressional and public debates over the power U.S. agencies have to collect and review intelligence information, especially data concerning individuals. In comparison, fewer than 1.3 million queries involving Americans' data were conducted between December 2019 and November 2020, according to the 38-page report. The report sought to provide a justification for the increase in queries during the last year.

"In the first half of the year, there were a number of large batch queries related to attempts to compromise U.S. critical infrastructure by foreign cyber actors," according to the report. "These queries, which included approximately 1.9 million query terms related to potential victims -- including U.S. persons -- accounted for the vast majority of the increase in U.S. person queries conducted by FBI over the prior year." The exact number of U.S. residents who potentially had their information reviewed isn't known because there's no precise way to measure the data, according to the report.
"Today's report sheds light on the extent of these unconstitutional 'backdoor searches,' and underscores the urgency of the problem," said senior staff attorney with the ACLU. "It's past time for Congress to step in to protect Americans' Fourth Amendment rights."

All of the Bases In DNA, RNA Have Now Been Found In Meteorites (sciencenews.org) 69

Space rocks that fell to Earth within the last century contain the five bases that store information in DNA and RNA, scientists report April 26 in Nature Communications. Science News reports: These "nucleobases" -- adenine, guanine, cytosine, thymine and uracil -- combine with sugars and phosphates to make up the genetic code of all life on Earth. Whether these basic ingredients for life first came from space or instead formed in a warm soup of earthly chemistry is still not known. But the discovery adds to evidence that suggests life's precursors originally came from space, the researchers say. Scientists have detected bits of adenine, guanine and other organic compounds in meteorites since the 1960s. Researchers have also seen hints of uracil, but cytosine and thymine remained elusive, until now.

Ordinary Copper Telephone Wire Could Carry Gigabit Broadband Speeds (newscientist.com) 129

Fibre-optic cable is being laid across the globe at great expense to speed up people's internet connections, but researchers claim that the copper telephone wire already in use across the country can achieve data rates three times higher than currently seen at a fraction of the price, at least over short distances. New Scientist: Their technique to boost speeds may help to ease the transition to nationwide fibre optic, and may also be of use in countries that use similar twisted-pair copper wire. Ergin Dinc at the University of Cambridge and his colleagues say that twisted pairs of copper wire, of the type used for decades as telephone lines and now repurposed for broadband internet, can support a frequency fives times higher than is currently used, which would dramatically improve data transmission rates. Above that limit, the researchers found that the wire essentially acts as an aerial and transforms any signal sent along it into radio waves that dissipate before reaching their destination. "These cables are actually very old, invented by Alexander Graham Bell, and since then no one has looked into the theoretical limits," says Dinc. He and his colleagues say that their findings may allow houses near fibre-optic cables to achieve higher speeds than they currently enjoy without the expense of running fibre all the way to their home. Fibre-optic cables carry groups of photons to represent data, and huge numbers of these groups can be sent along the line one after another without waiting for the first to arrive. Fibre connections in use today typically operate at 1 gigabit per second, but theoretical speeds could be many thousands of times higher.

NASA's Space Telecoms Network May Soon Be Outsourced (space.com) 23

vm shares a report from Space.com: SpaceX is among companies that might replace services of NASA's aging space telecoms constellation that has kept the International Space Station connected to Earth for decades. For years, NASA's Tracking and Data Relay Satellite (TDRS) constellation has served as the main link between the International Space Station and Earth, providing astronauts with constant connection to ground control as well as the ability to engage with the public and stay in touch with their loved ones. The American space agency, however, plans to retire the six aging satellites in the next decade and hand over their task to commercial companies. This month, the agency announced partnerships with six commercial satellite operators including SpaceX, U.K. company Inmarsat, American Viasat and Switzerland-based SES, to demonstrate how they could take care of NASA's space communication needs in the future. "We don't plan to launch any new TDRS satellites in the future," Eli Naffah, the manager of NASA's Commercial Services Project, who oversees the partnership with the commercial companies, told Space.com. "The plan is to allow the constellation to basically [reach the end of its life]. At some point later in this decade, we are going to have some diminished capability and the plan is for the [commercial companies] to come up with a different way of providing communication services to our missions."

"Back in the 1980s, when we developed TDRS, there really wasn't an ability on the commercial side to be able to provide this service," Naffah said. "But since then, the industry has far outpaced NASA's investment in this area. There's a lot of infrastructure, both on the ground and in orbit that is capable of providing these types of services to a spacecraft. [...] Hopefully, we can achieve some cost efficiencies in buying commercial services, get out of the business of operating networks, and really put more focus on science and exploration." According to Naffah, NASA will invest $278 million into the project over the next five years, with the agency's industry partners contributing a total of about $1.5 billion.
