A group of MIT scientists has created an emergency ventilator, which is affordable, and easily made using regular hospital devices. Interesting Engineering reports: A team of volunteers, scientists, physicians, and computer scientists at MIT known as E-Vent put their heads together three weeks ago to revive a 10-year-old ventilator project. The end result is a ventilator design that's affordable and easily replicated. The total cost of the device for the different parts is between $400 to $500, and the team plans on sharing their design online on their website so that manufacturers and companies can recreate the lifesaving device for hospitals around the world.

The device's main part already exists in most hospitals' inventory: Ambu resuscitation bags. Usually, these are manually operated by emergency technicians or medical professionals to keep the patient breathing until they are hooked up to a ventilator. The team at MIT has adapted the Ambu bags by attaching them to an automated mechanism that automatically pumps the bag with air in the same manner if a human were handling it. This method would alleviate the use of a person standing day and night by a patient's bedside -- something that's not currently possible in hospitals that are reaching over-capacity because of the rapidly spreading coronavirus -- and keep them breathing long enough to then be strapped to a proper ICU ventilator. There's currently no exact date for when the prototype info will be shared for all to use, but the team members have stated that they eventually want to secure the FDA approvals.

The state of New York hopes to "amplify" its response to COVID-19 by launching tech-driven products with top companies, and it's looking for professional volunteers with experience in software development, hardware deployment/end-user support, and data science (as well as areas like product management, design, operations management).

Meanwhile, IBM's 2020 "Call for Code Global Challenge" is a virtual hackathon with a $200,000 prize, and they've now "expanded its focus" to include the effects of COVID-19.

Tech columnist Mike Melanson writes: But this is just the beginning of the COVID-19 hackathon boom, which now includes efforts organized by tech giants, state governments, and grassroots initiatives alike. For example, the World Health Organization got together with technology companies and platforms such as AWS, Facebook, Giphy, Microsoft, Pinterest, Salesforce, Slack, TikTok, Twitter and WeChat to launch the COVID-19 Global Hackathon 1.0, which is running as we speak with a deadline for submissions of March 30th at 9 AM PST. If you're too late, fret not, for there are many more, such as the CODEVID-19 hackathon we mentioned last week that has a weekly rolling deadline. And deadlines aside, the U.S. Digital Response for COVID-19 is working to pair technology, data, and government professionals with those who need them, in a form of nationwide, technological mutual aid...

[T]he COVID-19 open-source help desk is "a fast-track 'stack overflow' where you can get answers from the very people who wrote the software that you use or who are experts in its use." And if you happen to be either an open source author or expert, feel free to pitch in on answering questions...

On the open data side of things, for example, GitHub offers a guide on open collaboration on COVID-19, while StackOverflow looks at the myriad ways to help the fight against COVID-19 from home. ProgrammableWeb has a list of developer hackathons to combat COVID-19, and even the Golang team offers some guidance for Go, the Go community, and the pandemic, with Erlang also joining in.

HP is teasing a Reverb G2 VR headset developed in tandem with Microsoft and Valve that should be "more immersive, comfortable and compatible" than previous-generation hardware. Engadget reports: The first Reverb wasn't a revolution in design, but it did stand out with a sharp 2,160 x 2,160 pixels per eye. It won't be surprising if HP pursues bragging rights once again, especially when its Twitter teaser claims the new Reverb is the "next benchmark" in VR gear. We wouldn't count on Valve dramatically influencing the design given that the Index remains its pride and joy, though. The new Reverb may be more gamer-friendly, but this is still likely to be aimed as much at professionals as it is enthusiasts.

An anonymous reader quotes a report from Food & Wine Magazine: Fried rice is one of those dishes where the name practically tells you how to make it. But the key to cooking perfect fried rice is in the details: not just the ingredients but also the equipment and technique. Traditionally, the dish is made in a wok with chefs continually tossing the rice to avoid caramelization and burning. It led a lab at the Georgia Institute of Technology to wonder, is there an optimal way to cook fried rice? Turns out, yes, and the pros have pretty much nailed it -- though the researchers do have a suggestion. Published in the Journal of the Royal Society Interface, the study "The physics of tossing fried rice" delivers on what the title promises -- analyzing the technique of five professional chefs to better understand their cooking technique.

[The] research confirmed that handling a wok is tough business. In the technique used by professionals, "The key is using the stove rim as the fulcrum of [a] see-saw motion," according to the paper, resulting in the rice being tossed at a rapid 2.7 times per second. "We show that the wok is always contacting the stove and getting support from it so that the chef wouldn't have to lift it," Hungtang Ko, a PhD student in Mechanical Engineering at Georgia Tech, who co-authored the study, stated. "Most importantly, we show that the wok motions adopted by the chefs are really some sort of optimal [motion] for the rice grains to jump the farthest." And yet, after developing a mathematical model that successfully described the wok tossing process, Ko and co-author David Hu, the professor who runs the lab, came up with some potential improvements. "Tossing is a combination of two independent motions, a side to side motion and a see-saw motion, allowing rice grains to slide around the wok as well as to jump off the surface," the conclusion of the paper states. "We identify two critical parameters that chefs can vary: the frequency of tossing and the phase lag between the two motions applied. By filming professional chefs, we found that, at the frequency chosen by chefs, the phase difference performed is optimal for mixing. We suggest that future chefs increase the frequency of motion, which may enable rice to jump further, and promote cooling and mixing." Ko and Hu point out that 64.5 percent of Chinese restaurant chefs complain of shoulder pain, likely in part to all that wok work.

As a result, Ko believes his research might help "guide the design of robots that can mix granular materials efficiently and rapidly." He adds: "It also paves ways for designing assistive robotic devices that chefs can wear to reduce the burden from the arm muscles."

"Boeing is pushing ahead on a plan to cut about 900 inspectors, replacing their jobs with technology improvements at its Seattle area factories, despite being under fire for software flaws in the 737 Max and quality issues in its other aircraft," reports USA Today.

"The union has raised an outcry, calling it a 'bad decision' that will 'eliminate the second set of eyes on thousands of work packages' in its newsletter to members." Some 451 inspectors will be transferred to other jobs this year, and about the same number next year, out of a total of about 3,000 at its commercial aircraft operations in the Seattle area, the International Association of Machinists and Aerospace Workers, Local 751, has told its members.... When it comes to paring its inspection staff on the West Coast, Boeing says the "QA Transformation Plan" won't undermine safety. Substituting technology gains, it says, will increase quality and effect only "stable" procedures, those in which there is a low probability of mistakes.

For instance, Boeing says when it is bringing out a new aircraft with wings made out of composites, there is equipment now that can do the inspections more thoroughly than humans. Once the inspection equipment has verified that it can do the job -- with humans overseeing the process -- traditional inspectors can be redeployed to other tasks. "As we identify and reduce second-layer inspections for stable processes, quality assurance professionals will be redeployed and take on new roles such as leading and supporting efforts to prevent defects and rework," Boeing said in a statement. It adds that it is working to try to convince regulators and others that the changes "will not jeopardize our quality, but will, in fact, lead to higher levels."

So far, the Federal Aviation Administration hasn't given the plan a ringing endorsement... And skeptics are emerging. Ralph Nader, the consumer advocate who lost a niece when the Ethiopian Airlines jet crashed and who believes the 737 Max design is fatally flawed, is leery of substituting machines for people when it comes to quality. "They still haven't learned the lesson that risky automation does not replicate experienced human intelligence," he said. "There is no comparison. There is all kinds of human intuition that can't be translated into computer code."

schwit1 shares a report: At least eight studies in the last seven years have looked at what happens specifically in a room accumulating carbon dioxide, a main ingredient in our exhalations. While the results are inconsistent, they are also intriguing. They suggest that while the kinds of air pollution known to cause cancer and asthma remain much more pressing as public health concerns, there may also be pollutants whose most detrimental effects are on the mind, rather than the body.

So can you trust the decisions made in small rooms? How much does the quality of air indoors affect your cognitive abilities? And as our knowledge of indoor air's effects grows, do we need to revise how we design and use our buildings? Buildings in the United States have grown better sealed in the last 50 years, helping reduce energy used in heating and cooling. That's also made it easier for gasses and other substances released by humans and our belongings to build up inside. Although indoor air quality is not as well monitored as the air outdoors, scientists and ventilation professionals have extensively monitored carbon dioxide indoors. Higher CO2 levels -- say, above 1,200 parts per million (ppm) -- often indicate a low ventilation rate. Worrisome substances emitted by new furniture, office supplies and carpets could be accumulating in the air.

Monotype today introduced the Helvetica Now typeface, a new family of fonts that have been carefully and respectfully re-drawn for the modern era. From a report: Consisting of 48 fonts and three optical sizes, the typeface has been produced from size-specific drawings and with size-specific spacing and is the first redesign in 35 years of what many argue is the world's most ubiquitous font, Helvetica. Every character has been redrawn and refit and a host of useful alternates have been added to help brands meet modern-day branding challenges. Espousing the simplicity, clarity, timelessness and global appeal of the typeface's storied tradition, the Helvetica Now design aims to be more sophisticated and graceful than its predecessors. An extremely popular and well-known typeface, the Helvetica family has been used by countless brands and creative professionals, in millions of designs since its inception. The typeface embodies clean and versatile design, and the Helvetica Now typeface continues the tradition established by the Helvetica and Neue Helvetica families while introducing a number of improvements.

samleecole writes: For years security professionals and election integrity activists have been pushing voting machine vendors to build more secure and verifiable election systems, so voters and candidates can be assured election outcomes haven't been manipulated. Now they might finally get this thanks to a new $10 million contract the Defense Department's Defense Advanced Research Projects Agency (DARPA) has launched to design and build a secure voting system that it hopes will be impervious to hacking.

The first-of-its-kind system will be designed by an Oregon-based firm called Galois, a longtime government contractor with experience in designing secure and verifiable systems. The system will use fully open source voting software, instead of the closed, proprietary software currently used in the vast majority of voting machines, which no one outside of voting machine testing labs can examine. More importantly, it will be built on secure open source hardware, made from special secure designs and techniques developed over the last year as part of a special program at DARPA. The voting system will also be designed to create fully verifiable and transparent results so that voters don't have to blindly trust that the machines and election officials delivered correct results.

AppleInsider has obtained a note to investors from KGI analyst Ming-Chi Kuo that says Apple's 2017 laptop line will focus on internal component updates, including the platform-wide adoption of Intel's Kaby Lake architecture. What's more is that Apple is expected to manufacture a 15-inch MacBook Pro with up to 32GB of RAM in the fourth quarter of 2017. AppleInsider reports: Apple took flak in releasing its latest MacBook Pro with Touch Bar models with a hard memory cap of 16GB, an minimal allotment viewed as a negative for imaging and video professionals. Responding to customer criticism, Apple said the move was made in a bid to maximize battery life. Essentially, the Intel Skylake CPUs used in Apple's MacBook Pro only support up to 16GB of LPDDR3 RAM at 2133MHz. Though Intel does make processors capable of addressing more than 16GB of memory, those particular chipsets rely on less efficient DDR4 RAM and are usually deployed in desktops with access to dedicated mains power. In order to achieve high memory allotments and keep unplugged battery life performance on par with existing MacBook Pro models, Apple will need to move to an emerging memory technology like LPDDR4 or DDR4L. Such hardware is on track for release later this year. As for the 12-inch MacBook, Kuo believes next-generation versions of the thin-and-light will enter mass production in the second quarter with the same basic design aesthetic introduced in 2015. New for 2017 is a 16GB memory option that will make an appearance thanks to Intel's new processor class.

Sounds, especially those made by other humans, have ranked as the top distraction in the workplace, according to design expert Alan Hedge of Cornell. A staggering 74 percent of workers say they face "many" instances of disturbances and distractions from noise. Hedge says the noise is generally coming from another person, though it's much more disturbing when it's a machine that is making it. NPR reports: The popularity of open offices has exacerbated the problem. The University of California's Center for the Built Environment has a study showing workers are happier when they are in enclosed offices and less likely to take sick days. This does not bode well for some workers facing cold and flu season, when hacking coughs make the rounds. [...] Rue Dooley, an adviser at the Society for Human Resource Management, says HR professionals often call in, asking how to manage co-worker complaints about various bodily noises.

theodp writes: The Microsoft-sponsored PBS 'reality' show Code Trip, in which Roadtrip Nation and Microsoft YouthSpark partnered to send three students across the U.S. on a "transformative journey into computer science" is getting a spin-off. According to the National Science Foundation Award Abstract for a Computer Science Roadtrip (CS Roadtrip), $199,866.00 in funding has been awarded for a pilot project that began in October "to design and develop pilot materials for a Computer Science Roadtrip (CS Roadtrip)."

From the abstract: "Through this pilot project, Roadtrip Nation will lay the groundwork and provide proof-of-concept for a CS Roadtrip, leveraging a combination of multimedia deliverables, an evidence-based educational curriculum, and dynamic engagement strategies that will provide critical connections between students' natural interests, positive role models who align with those interests, and corresponding CS educational and career pathways. To that end, the CS Roadtrip Pilot will develop up to four student-facing videos that feature the stories of diverse computing professionals, appropriate for on-air, online, and classroom purposes, along with the appropriate Learning Guides."

The NSF study's Principal Investigator is Roadtrip Nation co-founder Mike Marriner, who explained his company's relationship with Microsoft in a July 30th press release, "Roadtrip Nation is proud to partner with Microsoft's YouthSpark initiative not only to inform others of the many career routes one can take with a computer science background, but also to engage in the much-needed conversation of diversifying the tech field with more pluralistic perspectives."

An anonymous reader writes Engadget takes a look at Ford's new Research and Innovation Center located in Palo Alto. The company hopes to use the new facility to speed the development of projects such as autonomous cars and better natural voice recognition. From the article: "This isn't Ford's first dance with the Valley — it actually started its courtship several years ago when it opened its inaugural Silicon Valley office in 2012. The new center, however, is a much bigger effort, with someone new at the helm. That person is Dragos Maciuca, a former Apple engineer with significant experience in consumer electronics, semiconductors, aerospace and automotive tech. Ford also hopes to build a team of 125 professionals under Maciuca, which would make the company one of the largest dedicated automotive research teams in the Valley."

New submitter Andrewkov writes: BlackBerry released its new Passport phone today. It has a square 4.5" screen and a physical keyboard, and it's aimed at corporate users. The company hopes the larger size, Siri-like voice recognition, 30-hour battery life, and improved security will buoy its market share. Early reviews are not terribly favorable — the Wall Street Journal says BlackBerry is still behind on the software, and "The bulky, awkward design and the unfamiliar keyboard make it hard to justify finding space for it in a pocket or bag." The Verge said, "[T]he Passport got in the way of getting work done more than it helped." Re/code calls it a phone only a BlackBerry user will love.

mpicpp writes with news that UPS will be expanding their 3D printing services. UPS announced plans Monday to bring in-store 3-D-printing services to nearly 100 stores across the country, billing itself as the first national retailer to do so. With the UPS system, customers can submit their own designs for objects like product prototypes, engineering parts and architectural models that are then printed on a professional-quality 3-D printer made by Stratasys. Prices vary depending on the complexity of the object; an iPhone case would be about $60, while a replica femur bone would be around $325. UPS can also connect customers with outside professionals who charge an hourly rate to help produce a design file for the printer. It generally takes about four or five hours to print a simple object, with more complex items taking a day or more. The program started as a pilot at six locations last year, and UPS says those stores "saw demand for 3-D print continuing to increase across a broad spectrum of customers."
