Researchers at Zhejiang University and Microsoft claim they've developed an AI system -- DeepSinger -- that can generate singing voices in multiple languages by training on data from music websites. From a report: In a paper published on the preprint Arxiv.org, they describe the novel approach, which leverages a specially-designed component to capture the timbre of singers from noisy singing data. The work -- like OpenAI's music-generating Jukebox AI -- has obvious commercial implications. Music artists are often pulled in for pick-up sessions to address mistakes, changes, or additions after a recording finishes. AI-assisted voice synthesis could eliminate the need for these, saving time and money on the part of the singers' employers.

But there's a darker side: It could also be used to create deepfakes that stand in for musicians, making it seem as though they sang lyrics they never did (or put them out of work). In what could be a sign of legal battles to come, Jay-Z's Roc Nation label recently filed copyright notices against videos that used AI to make him rap Billy Joel's "We Didn't Start the Fire." As the researchers explain, singing voices have more complicated patterns and rhythms than normal speaking voices. Synthesizing them requires information to control the duration and the pitch, which makes the task challenging. Plus, there aren't many publicly available singing training data sets, and songs used in training must be manually analyzed at the lyrics and audio level.

Fans of Microsoft's famous Flight Sim won't have long to wait until the latest incarnation arrives. From a report: This promises to be the most detailed and authentic version to date, with incredibly accurate landscapes that are ever-changing, coupled with highly detailed aircraft, covering everything from light planes to commercial jets. Microsoft Flight Simulator has been around since 1982 -- feeling old yet? -- and the new version will be available in three editions -- Standard ($59.99), Deluxe ($89.99) and Premium Deluxe ($119.99). The Deluxe edition comes with five extra planes and five extra international airports. The Premium Deluxe adds a further five planes and airports on top of that. Microsoft Flight Simulator launches on August 18, and you can pre-order on Windows 10 or pre-install with Xbox Game Pass for PC (Beta) today.

Sphere packing might seem like a topic only a mathematician could love. Who else could get excited about finding the most efficient way to arrange circles in the plane, or spheres in space? But right now, millions of people all over the world are thinking about this very problem. From a report: Determining how to safely reopen buildings and public spaces under social distancing is in part an exercise in geometry: If each person must keep six feet away from everyone else, then figuring out how many people can sit in a classroom or a dining room is a question about packing non-overlapping circles into floor plans. Of course there's a lot more to confronting COVID than just this geometry problem. But circle and sphere packing plays a part, just as it does in modeling crystal structures in chemistry and abstract message spaces in information theory.

It's a simple-sounding problem that's occupied some of history's greatest mathematicians, and exciting research is still happening today, particularly in higher dimensions. For example, mathematicians recently proved the best way to pack spheres into 8- and 24-dimensional space -- a technique essential for optimizing the error-correcting codes used in cell phones or for communication with space probes. So let's take a look at some of the surprising complications that arise when we try to pack space with our simplest shape. If your job involves packing oranges in a box or safely seating students under social distancing, the size and shape of your container is a crucial component of the problem. But for most mathematicians, the theory of sphere packing is about filling all of space. In two dimensions, this means covering the plane with same-size circles that don't overlap.

Type a query into the Google search bar on a smartphone and there's a good chance the results will be dominated by advertising. From a report: That stems from a decision in 2015 to test a fourth ad, rather than three, at the top of search results. Some employees opposed the move at the time, saying it could reduce the quality of Google's responses, according to people familiar with the deliberations. But the company brushed aside those concerns because it was under pressure to meet Wall Street growth expectations, one of the people said. By 2016, the extra marketing slot was a regular feature. It's one of the many ways the search leader has altered how it presents results since its early days. Another example is the pre-packaged information Google often displays in a box at the top of a page, rather than sending users to other websites.

Phased in gradually over years, changes like these have gone largely unnoticed by legions of consumers who regularly turn to Google to call up information and hunt for bargains. The company says these changes support its mission to organize the world's information and make it useful and accessible to everyone. But to many web publishers and other businesses that have historically relied on the internet giant to send users to their sites, Google's subtle tweaks have siphoned off vital traffic and made it harder -- and costlier -- to reach customers online.

Hammeh writes: Semiconductor maker Analog Devices said on Monday it would buy rival Maxim Integrated Products for about $21 billion in the largest U.S. deal this year, aiming to boost its market share in automotive and 5G chipmaking. The deal, which is also Analog's biggest, will create a chipmaking force with a combined enterprise value of about $68 billion that will compete with larger rivals including Texas Instruments). Analog Devices Chief Executive Vincent Roche told Reuters in an interview that the combined engineering teams would help the resulting company design more specialized, higher-margin chips for customers such as automakers. "If you're doing commodities, you're at the mercy of the of the heavy hammer of the procurement folks," Roche said. "But our game is about getting there first, getting out on the edge and making a real impact at the application level for our customers." The companies said the deal added Maxim's strength in automotive and data center markets to ADI's broad industrial, communications and digital healthcare segments.

The Democratic and Republican national committees have warned their staffs about using the Chinese-owned app TikTok. From a report: The Democratic National Committee warned Democratic campaigns, committees and state parties Friday to take additional security precautions when using TikTok. In the email, the DNC security team wrote, "We continue to advise campaign staff to refrain from using TikTok on personal devices. If you are using TikTok for campaign work, we recommend using a separate phone and account." Republican National Committee national press secretary Mandi Merritt said Saturday the RNC had longstanding guidance on TikTok. "The RNC has advised employees and stakeholders to not download the TikTok app on their personal devices," she said, citing "security concerns." The DNC had suggested to campaigns in a memo in December not to use TikTok, citing concerns about the app's "Chinese ties and potentially sending data back to the Chinese government."

Microsoft has been collaborating with Google to ensure that their tools interoperate and can help developers get their Progressive Web Apps (PWAs) into the Play Store. From a report: "We're glad to announce a new collaboration between Microsoft and Google for the benefit of the web developer community," Microsoft's Judah Gabriel Himango announced. "Microsoft's PWABuilder and Google's Bubblewrap are now working together to help developers publish PWAs in the Google Play Store." As Himango explains, PWABuilder is a Microsoft tool that helps developers build PWAs from existing websites and publish them in app stores, while Bubblewrap is a Google tool and library used to generate and sign Google Play Store packages from PWAs. After months of collaboration, the two firms have made some interesting progress towards integrating the tools. Now, PWABuilder utilizes Bubblewrap "under the hood," as Himango puts it, allowing developers to package PWAs for the Play Store with PWABuilder that support the new web shortcuts standard. (On Windows 10, web shortcuts appear as jump lists.)

Apple announced Monday that it is allocating $400 million toward affordable housing and homeowner assistance programs in California this year, as part of the $2.5 billion commitment announced in November. From a report: The housing crisis has worsened in the wake of the coronavirus pandemic, forcing states and cities to pause spending on affordable housing projects. Big Tech's wealth has been blamed by some for driving up housing prices in the San Francisco Bay Area and making it unaffordable for teachers, firefighters and other workers who support the region. Apple, along with Facebook, Google and Microsoft, committed a collective $5 billion to support affordable housing initiatives, but it ran into the reality that money alone can't solve the problem without changes to zoning and financing restrictions.

Public health officials in Houston are struggling to keep up with one of the nation's largest coronavirus outbreaks. They are desperate to trace cases and quarantine patients before they spread the virus to others. But first, they must negotiate with the office fax machine. From a report: The machine at the Harris County Public Health department in Houston recently became overwhelmed when one laboratory sent a large batch of test results, spraying hundreds of pages all over the floor. "Picture the image of hundreds of faxes coming through, and the machine just shooting out paper," said Dr. Umair Shah, executive director of the department. The county has so far recorded more than 40,000 coronavirus cases. Some doctors fax coronavirus tests to Dr. Shah's personal number, too. Those papers are put in an envelope marked "confidential" and walked to the epidemiology department. As hard as the United States works to control coronavirus, it keeps running into problems caused by its fragmented health system, a jumble of old and new technology, and data standards that don't meet epidemiologists' needs. Public health officials and private laboratories have managed to expand testing to more than half a million performed daily, but they do not have a system that can smoothly handle that avalanche of results.

America's studios, creators and marketers are relying, more than ever, on digital platforms that allow them to gauge what audiences like-- and would like to see more of. From a report: They're not just looking for test screenings, either. They're looking to check in with potential audiences at every stage of production, from before a script is written until the moment their new TV show, film or music video debuts. Ever since George Lucas ushered in the era of endless sequels (and prequels), Hollywood executives have tried to capitalize on the success of the Last Big Thing by churning out more of it. But content budgets are increasing far faster than established franchises can keep up. Netflix is projected to spend more on new and acquired content in 2020 -- $17 billion -- than Apple spent on research and development in 2019. With stakes that high, minimizing risk when creating new content "at scale" means treating it like any other mass-market product. Executives, producers, writers, directors and marketers need to be able to consistently craft programs that are more likely than not to find their target audiences. Critical approval and industry awards -- even box-office blowouts -- while nice, aren't the endgame for most.

Google said today it'll invest about $10 billion in India over the next five to seven years. The company's CEO, Sundar Pichai, said that money will be divided into investment equity investments, partnerships, and operational, infrastructure, and ecosystem investments. Investments will focus on four main areas: Information access in Indian languages.
Building products for the Indian market.
Empowering local businesses.
Leveraging AI for good in areas such as agriculture and education.

The world's fastest computer is now part of "a vast supercomputer-powered search for new findings pertaining to the novel coronavirus' spread" and "how to effectively treat and mitigate it," according to an emerging tech journalist at Nextgov.

It's part of a consortium currently facilitating over 65 active research projects, for which "Dozens of national and international members are volunteering free compute time...providing at least 485 petaflops of capacity and steadily growing, to more rapidly generate new solutions against COVID-19."

"What started as a simple concept has grown to span three continents with over 40 supercomputer providers," Dario Gil, director of IBM Research and consortium co-chair, told Nextgov last week. "In the face of a global pandemic like COVID-19, hopefully a once-in-a-lifetime event, the speed at which researchers can drive discovery is a critical factor in the search for a cure and it is essential that we combine forces...."

[I]ts resources have been used to sort through billions of molecules to identify promising compounds that can be manufactured quickly and tested for potency to target the novel coronavirus, produce large data sets to study variations in patient responses, perform airflow simulations on a new device that will allow doctors to use one ventilator to support multiple patients — and more. The complex systems are powering calculations, simulations and results in a matter of days that several scientists have noted would take a matter of months on traditional computers.
The Undersecretary for Science at America's Energy Department said "What's really interesting about this from an organizational point of view is that it's basically a volunteer organization."

The article identifies some of the notable participants:

• IBM was part of the joint launch with America's Office of Science and Technology Policy and its Energy Department.
• The chief of NASA's Advanced Supercomputing says they're "making the full reserve portion of NASA supercomputing resources available to researchers working on the COVID-19 response, along with providing our expertise and support to port and run their applications on NASA systems."
• Amazon Web Services "saw a clear opportunity to bring the benefits of cloud... to bear in the race for treatments and a vaccine," according to a company executive.
• Japan's Fugaku — "which surpassed leading U.S. machines on the Top 500 list of global supercomputers in late June" — also joined the consortium in June.

Other consortium members:

• Google Cloud
• Microsoft
• Massachusetts Institute of Technology
• Rensselaer Polytechnic Institute
• The National Science Foundation
• Argonne, Lawrence Livermore, Los Alamos, Oak Ridge and Sandia National laboratories.
• National Center for Atmospheric Research's Wyoming Supercomputing Center
• AMD
• NVIDIA
• Dell Technologies. ("The company is now donating cycles from the Zenith supercomputer and other resources.")

"One of the main reasons we're not all driving electric vehicles is the price," argues a transportation writer in Forbes — explaining how Tesla hopes to finally change that: The company is placing a huge bet on rechargeable battery technology that doesn't use cobalt. This is one of the main elements making lithium ion batteries so expensive. It's also fraught with political issues, since the mining can be in conflict areas like the Congo, and its production is considered quite polluting of the environment. But cobalt is used because it enables the energy density required in batteries intended to last for hundreds of miles per charge. A couple of months ago, it was revealed that Tesla was working with CATL on lithium iron phosphate (LFP) batteries, and these could be the real gamechanger. LFP batteries don't use cobalt and have a roadmap to push well past the magical $100 per kWh (wholesale) that is considered the threshold for EVs being cheaper than Internal Combustion Engine (ICE) vehicles...

Tesla has also recently patented technology for cathodes that significantly improves the number of charge cycles... The new Tesla technology, patented by the company's battery team led by Jeff Dahn, can increase charge cycles to nearly 4,000, which would be more like 75 years if charged once a week — hence the talk of million-mile batteries. More recently, the Tesla team headed by Jeff Dahn patented some new technology for lithium metal/anode free batteries, which could drastically improve energy density and thereby considerably reduce costs. These technologies, if they become commercially viable, could revolutionize battery durability and price, and there's another technology called all-polymer batteries on the horizon that is being developed by a former Nissan senior researcher, which he claims could cut 90% off the current price.

But these are improvements for the future that may not happen, and cobalt-free lithium iron phosphate batteries are here now. Tesla will be using LFP for the batteries in its Chinese Model 3, after receiving government approval to do so. It is estimated that using LFP batteries will allow a 15-20% reduction in manufacturing cost. Taking calculations regarding how much of a car's cost is batteries into account, this could make EVs a mere 10% more expensive than ICE instead of 30%, which will be easy to regain in cheaper running costs over a year or two of ownership. It will also give EVs an even greater lead over fuel-cell technology, making it even less likely that hydrogen will be the future of electric cars.

The time is fast approaching when EVs are not just more ecological and cheaper to run than ICE cars, but cheaper to buy too, and batteries free of cobalt are a key step in that direction. That's why Tesla's shift to LFP is so significant — it could be the final nail in the coffin for fossil fuel vehicles.
