Blood pressure e-tattoo promises continuous, mobile monitoring:

Blood pressure is one of the most important indicators of heart health, but it's tough to frequently and reliably measure outside of a clinical setting. For decades, cuff-based devices that constrict around the arm to give a reading have been the gold standard. But now, researchers at The University of Texas at Austin and Texas A&M University have developed an electronic tattoo that can be worn comfortably on the wrist for hours and deliver continuous blood pressure measurements at an accuracy level exceeding nearly all available options on the market today.

[...] Graphene is one of the strongest and thinnest materials in existence, and it is a key ingredient in the e-tattoo. It is similar to graphite found in pencils, but the atoms are precisely arranged into thin layers.

[...] The device takes its measurements by shooting an electrical current into the skin and then analyzing the body's response, which is known as bioimpedance. There is a correlation between bioimpedance and changes in blood pressure that has to do with blood volume changes. However, the correlation is not particularly obvious, so the team had to create a machine learning model to analyze the connection to get accurate blood pressure readings.

In medicine, cuff-less blood pressure monitoring is the "holy grail," Jafari said, but there isn't a viable solution on the market yet. It's part of a larger push in medicine to use technology to untether patients from machines while collecting more data wherever they are, allowing them to go from room to room, clinic to clinic and still get personalized care.

https://asia.nikkei.com/Business/Technology/Internet-Explorer-shutdown-to-cause-Japan-headaches-for-months

Microsoft bids farewell to Internet Explorer on Thursday, stirring a sense of panic among many businesses and government agencies in Japan that waited to update their websites until the last minute.

Since April, Tokyo-based software developer Computer Engineering & Consulting has been inundated with requests for help.

[...] "They have known [about the phaseout] for a long time, but they must have postponed taking actions," said a CEC official, who expects the chaos among the procrastinated customers to last for "a few months."

[...] They said the browser was used for employee attendance management, expenses settlement and other internal tools. In some cases, they have no choice but to use Internet Explorer because of clients' systems used to handle orders. Over 20% of these respondents did not know or had not figured out how to transition to other browsers after Internet Explorer's retirement.

Government agencies are particularly slow to respond. The portal site for information on government procurement and bidding will switch its recommended browsers to Microsoft's new Edge and Google Chrome on Thursday. But for Japan Pension Service, notices concerning online applications must be viewed in Edge's Internet Explorer mode. The website of a government-backed mutual aid corporation for private schools still listed Internet Explorer as its only recommended browser.

Atmospheric samples covering pollution particles analyzed using neutrons for the first time:

In a new study, published in Environmental Science: Atmospheres, scientists have used neutron reflection to examine pollutants taken from three different environments: urban, Antarctic, and wood burning materials. They were able to measure how these materials react with the hydroxyl radical OH—one of the most reactive molecules found in the atmosphere.

[...] Professor Martin King from Royal Holloway's Department of Earth Sciences, said: "Our work clearly demonstrates that to understand coating of atmospheric aerosols we must use real samples extracted from the atmosphere rather than only pure compounds from a chemist's shelf as simulants because their behavior is different and not representative."

[...] "This makes it easier to study them and possible to understand the detailed mechanisms at work, so remains an important approach to enhance our understanding of key atmospheric processes. However, this work should be complemented by studies of real samples collected from a diverse set of locations."

The process for collecting and testing "real" samples has been carefully designed by the researchers. The material is collected in situ on quartz filters which allows the particles to attach and form a film specific to distinct environments across the globe. This product is then rinsed into a solution, transported to a neutron facility, where the solution is evaporated to reveal the film.

Inside the neutron facility, neutrons are reflected from the film to follow its reaction with the OH radicals to ultimately establish how rapidly these films would break down on atmospheric particles.

New Understanding of Earth's Architecture: Updated Maps of Tectonic Plates:

New models that show how the continents were assembled are providing fresh insights into the history of the Earth and will help provide a better understanding of natural hazards like earthquakes and volcanoes.

"We looked at the current knowledge of the configuration of plate boundary zones and the past construction of the continental crust," said Dr. Derrick Hasterok, Lecturer, Department of Earth Sciences, University of Adelaide who led the team that produced the new models.

"The continents were assembled a few pieces at a time, a bit like a jigsaw, but each time the puzzle was finished it was cut up and reorganized to produce a new picture. Our study helps illuminate the various components so geologists can piece together the previous images.

"We found that plate boundary zones account for nearly 16 percent of the Earth's crust and an even higher proportion, 27 percent, of continents."

[...] "The biggest changes to the plate model have been in western North America, which often has the boundary with the Pacific Plate drawn as the San Andreas and Queen Charlotte Faults. But the newly delineated boundary is much wider, approximately 1500 km, than the previously drawn narrow zone.

Now China wants to censor online comments:

The new changes affect Provisions on the Management of Internet Post Comments Services, a regulation that first came into effect in 2017. Five years later, the Cyberspace Administration wants to bring it up to date.

"The proposed revisions primarily update the current version of the comment rules to bring them into line with the language and policies of more recent authority, such as new laws on the protection of personal information, data security, and general content regulations," says Jeremy Daum, a senior fellow at Yale Law School's Paul Tsai China Center.

[...] But recently, there have been several awkward cases where comments under government Weibo accounts went rogue, pointing out government lies or rejecting the official narrative. That could be what has prompted the regulator's proposed update.

Chinese social platforms are currently on the front lines of censorship work, often actively removing posts before the government and other users can even see them. ByteDance famously employs thousands of content reviewers, who make up the largest number of employees at the company. Other companies outsource the task to "censorship-for-hire" firms, including one owned by China's party mouthpiece People's Daily. The platforms are frequently punished for letting things slip.

Beijing is constantly refining its social media control, mending loopholes and introducing new restrictions. But the vagueness of the latest revisions makes people worry that the government may ignore practical challenges. [...] The tricky question is, no one knows if the government intends to enforce this immediately.

Amazon Will Pilot Drone Delivery in California This Year:

All sorts of wacky solutions have been proposed for better package delivery, from an underground "hyperloop" network of pipes to swarms of last-mile robots dispatched from mothership vans.

Let's not forget ever-elusive delivery drones. The widespread assumption was that Amazon would be the first to have its packages take to the skies, but as it turned out, Walmart beat them to the punch, piloting drone delivery in North Carolina in 2020.

Now Amazon's catching up. The company announced this week that it's starting drone delivery service in Lockeford, California later this year. South-east of Sacramento in the state's hot, dry Central Valley area, the town had a population of just 3,521 as of the 2020 census. An Amazon press release says the town has "historic links" to the aviation industry thanks to a former resident who built and flew planes there in the early 1900s.

The company doesn't give additional details around why it chose Lockeford for the Prime Air pilot, though the town's rural location, the fact that most customers there have backyards for the drones to drop packages in, and the lack of numerous obstacles you'd find in a more urban or densely-populated area likely all factored in.

[...] On the safety front, among other measures, Amazon has built what it calls an "industry-leading sense-and-avoid system" to keep its drones from crashing into things—things like other aircraft, people, pets, or unexpected obstacles (like, say, a chimney or an antenna). When a drone's sensors detect objects within a certain radius of it, it automatically changes course, and as it descends to drop packages, it checks that the surrounding space is clear.

Regulators in the EU first began probing tech giants' advertising dominance last year:

While Google's multiple antitrust cases continue to drag on here in the U.S., it looks like the search giant's starting to make a few concessions across the pond. Reuters reports that Google's parent company, Alphabet, has made an offer to European Union regulators in response to an ongoing investigation into the tech giants' adtech business: Don't fine us, and we'll let other companies place their ads on YouTube.

Alphabet has reportedly offered to allow its rival advertising technology companies to place ads beside YouTube videos in negotiations with the European Commission, rather than obligating them to use Google Ad Manager, Display & Video 360, and Google Ads to do so. [...]

Amazon has reportedly ceded ground in a similar antitrust investigation. The ecommerce company has offered to boost third-party sellers' visibility in its online marketplace and to share shopper data with them so as to avoid fines, Reuters reports. European regulators could fine Google and Amazon up to 10% of the companies' global revenue if they do conclude the tech giants engaged in anti-competitive practices.

In many ways, the EU probe mirrors another stateside antitrust case against the tech giant that's currently being spearheaded by Texas Attorney General Ken Paxton. [...]

The biggest difference between the Texas case and the EU case, if the Reuters report is to be believed, would be Google's response. Google filed a motion to dismiss Paxton's case at the start of 2022 on the grounds that, essentially, Google toppled the ad market because it's really good at innovating, and those thousands of other companies just aren't.

"State Plaintiffs' complaint—cheered on by a handful of Google's rivals who have failed to invest properly, compete successfully, or innovate consistently—might serve the narrow interests of those rivals," Google wrote in the motion. "But it also threatens to stifle the dynamism that drives Google and other firms to deliver the products on which businesses and consumers depend every day."

A new data-driven approach looks at practices that are good for the earth and profitable for farmers:

[T]he agricultural industry contributes about 10% of U.S. greenhouse gas (GHG) emissions. Because the amount of land dedicated for agriculture is limited, farmers need to find more ways to operate efficiently, sustainably and profitably while also reducing GHG emissions. With new practices, farmers can make farms a net sink of CO2, helping the U.S. reach its goal of achieving net zero emissions by 2050.

Sustainable intensification is a two-prong approach many think could help. It tries to optimize land use and management practices for maximum farmland productivity at the same time it tries to minimize associated environmental impact. The trick is finding the right balance between the two objectives.

[...] "The concept of sustainable intensification of farming was applied into more broadscale landscape application," said one of the article's co-authors, Hoyoung Kwon, a principal environmental scientist in Argonne's Energy Systems and Infrastructure Analysis (ESIA) division. ​"We considered productivity and GHG emissions, attempted to optimize land management tactics and products, and investigated different trade-offs that improve the land and land productivity."

For example, farmers can clear and repurpose corn crop residue (or ​"stover") for biofuel, but a percentage of stover can remain in the soil for valuable nutrient and carbon sources for future crops. Farmers can plant cover crops during the winter (or ​"fallow") season, to supplement removed stover. The authors took into account energy, which has an emissions cost of planting of cover crops to holistically address net benefits of stover removal and cover crop planting. Farmers can also reduce how much land they till after a growing season ends, which lessens decay and reduces the amount of CO2 that emanates from the soil. However, the farmer has to till some of the land to be ready for the next growing season.

[...] According to the study, harvesting 30% of the corn stover for biofuel production would increase farm revenues, double net profitability and increase overall biofuel production from the landscape by 17–20%. Removal of the stover would also mitigate GHGs somewhat, but it reduced the baseline amount of good carbon in the soil by 40%. In comparison, integrated approaches that include winter cover cropping and/or tillage intensity reduction would increase carbon in the soil, improve farm profitability and mitigate more GHGs.

"We focused on corn and soy but our approach could be extended to other crops," said Hawkins. ​"Many farms today are large, industrial farms that are high-tech and rely much more on high resolution data. We want to give farmers, regional planners and others in agricultural management a tool to calculate how to use land sustainably and get the most value out of the land. This will further both profitability and environmental goals."

Reseachers training 'hero rats' to locate earthquake survivors - National:

When Donna Kean moved from Scotland to Tanzania, she had more than just the culture shock to deal with.

[...] "With the rats, I was very surprised at just how intelligent they are and how trainable and how quickly they can learn, it was amazing."

For the past year she has been working with the NGO APOPO, training rats to become invaluable members of earthquake search and rescue teams.

[...] The rats will wear a special little backpack containing a camera, a location transmitter and a two-way radio, allowing rescuers to communicate with the person who is trapped.

Rats are trained to activate a switch on their backpack when they find a person in the rubble, transmitting a precise location back to rescuers.

[...] Researchers at APOPO have taken into account that injured and traumatized earthquake survivors may not exactly welcome a rat scratching around beside them.

"One thing that we've been considering is that [the rats] might play a message like an audio recording that says something like, 'I am a rescue rat, I'm well trained. I'm here to help you,'" said Kean.

"Something along those lines, we'll think of the ideal message to put people at ease."

[...] Kean says the rats would not put any rescue dogs out of work, but would complement human and canine teams.

NASA's next Mars copter to have rotors tested in Japan:

As the search for life beyond Earth heats up, Japan's Tohoku University is working with NASA to test whether the American space agency's next-generation Mars helicopter can take flight in the red planet's extremely thin atmosphere.

NASA's Ingenuity helicopter was landed on Mars in February 2021. That April, it became the first aircraft to make a powered, controlled flight on a planet other than Earth. A wind tunnel at Tohoku University will be used to test the blades of Ingenuity's successor, according to a Tuesday release.

Mars has an atmosphere less than 1% as thin as Earth's, as well as roughly a third of the gravity. This means that an aircraft on Mars needs to produce around 33 times as much lift as a counterpart on Earth in order to fly.

Tohoku University's wind tunnel can create atmospheric conditions similar to Mars. The university will work with NASA to check whether the blades for the next-generation helicopter can produce enough lift when subjected to winds at a hundredth of Earth's standard air pressure.

[...] Japan plans to launch its Martian Moons Exploration mission in fiscal 2024 to collect a sample from the Martian moon of Phobos and bring it back to Earth, leveraging experience from the Hayabusa and Hayabusa-2 asteroid probes. Separately, researchers from the Japan Aerospace Exploration Agency and elsewhere are working on their own Martian aircraft.

Arthur T Knackerbracket has processed the following story:

According to a new research study, your brain can send out a burst of norepinephrine when it needs you to pay attention to something important.

When your brain needs you to pay attention to something important, one way it can do that is to send out a burst of noradrenaline, according to a new MIT study.

This neuromodulator, produced by a structure deep in the brain called the locus coeruleus, can have widespread effects throughout the brain. In a study of mice, the MIT team found that one key role of noradrenaline, also known as norepinephrine, is to help the brain learn from surprising outcomes.

“What this work shows is that the locus coeruleus encodes unexpected events, and paying attention to those surprising events is crucial for the brain to take stock of its environment,” says Mriganka Sur, the Newton Professor of Neuroscience in MIT’s Department of Brain and Cognitive Sciences, a member of MIT’s Picower Institute for Learning and Memory, and director of the Simons Center for the Social Brain.

In addition to its role in signaling surprise, the researchers also discovered that noradrenaline helps to stimulate behavior that leads to a reward, particularly in situations where there is uncertainty over whether a reward will be offered.

[...] Previous studies of the locus coeruleus, the brain’s primary source of noradrenaline, have shown that it receives input from many parts of the brain and also sends its signals far and wide. In the new study, the MIT team set out to study its role in a specific type of learning called reinforcement learning, or learning by trial and error.

For this study, the researchers trained mice to push a lever when they heard a high-frequency tone, but not when they heard a low-frequency tone. When the mice responded correctly to the high-frequency tone, they received water, but if they pushed the lever when they heard a low-frequency tone, they received an unpleasant puff of air.

The mice also learned to push the lever harder when the tones were louder. When the volume was lower, they were more uncertain about whether they should push or not. And, when the researchers inhibited activity of the locus coeruleus, the mice became much more hesitant to push the lever when they heard low volume tones, suggesting that noradrenaline promotes taking a chance on getting a reward in situations where the payoff is uncertain.

“The animal is pushing because it wants a reward, and the locus coeruleus provides critical signals to say, push now, because the reward will come,” Sur says.

The researchers also found that the neurons that generate this noradrenaline signal appear to send most of their output to the motor cortex, which offers more evidence that this signal stimulates the animals to take action.

[...] The researchers now plan to explore the possible synergy between noradrenaline and other neuromodulators, especially dopamine, which also responds to unexpected rewards. They also hope to learn more about how the prefrontal cortex stores the short-term memory of the input from the locus coeruleus to help the animals improve their performance in future trials.

Experts say some hospitals' use of an ad tracking tool may violate a federal law protecting health information :

A tracking tool installed on many hospitals' websites has been collecting patients' sensitive health information—including details about their medical conditions, prescriptions, and doctor's appointments—and sending it to Facebook. The Markup tested the websites of Newsweek's top 100 hospitals in America. On 33 of them we found the tracker, called the Meta Pixel, sending Facebook a packet of data whenever a person clicked a button to schedule a doctor's appointment. The data is connected to an IP address—an identifier that's like a computer's mailing address and can generally be linked to a specific individual or household—creating an intimate receipt of the appointment request for Facebook.

[...] The Meta Pixel sends information to Facebook via scripts running in a person's internet browser, so each data packet comes labeled with an IP address that can be used in combination with other data to identify an individual or household.

HIPAA lists IP addresses as one of the 18 identifiers that, when linked to information about a person's health conditions, care, or payment, can qualify the data as protected health information. Unlike anonymized or aggregate health data, hospitals can't share protected health information with third parties except under the strict terms of business associate agreements that restrict how the data can be used.

In addition, if a patient is logged in to Facebook when they visit a hospital's website where a Meta Pixel is installed, some browsers will attach third-party cookies—another tracking mechanism—that allow Meta to link pixel data to specific Facebook accounts.

[...] Houston Methodist Hospital, in Texas, was the only institution to provide detailed responses to The Markup's questions. The hospital began using the pixel in 2017, spokesperson Stefanie Asin wrote, and is "confident" in Facebook's safeguards and that the data being shared isn't protected health information.

[...] Asin added that Houston Methodist believes Facebook "uses tools to detect and reject any health information, providing a barrier that prevents passage of [protected health information]."

[...] "The evil genius of Facebook's system is they create this little piece of code that does the snooping for them and then they just put it out into the universe and Facebook can try to claim plausible deniability," said Alan Butler, executive director of the Electronic Privacy Information Center. "The fact that this is out there in the wild on the websites of hospitals is evidence of how broken the rules are."

NASA's TESS Finds Buzzing Cosmic Neighborhood With Two Super-Earths:

Here's your friendly reminder that our solar system is but a molecule of water in the universe's ocean.  

NASA's Transiting Exoplanet Satellite Survey, better known as TESS, has spotted a buzzing galactic neighborhood only 33 light-years away from our planet. It has a central star, a couple of planets circling that star, and according to the scientists behind this alternate reality discovery, there are at least two terrestrial, Earth-size worlds in the pack.

[...] What we know so far is that the system's host star is dubbed HD 260655 and is relatively small, cool and categorized as an M-dwarf. M-dwarves are significantly less massive than our sun, a G-type main sequence star, yet are 10 times as numerous throughout the universe.

[...] The inner planet orbits its star every 2.8 Earth days and is about 1.2 times the size of Earth and twice as massive. The other foreign world orbits every 5.7 Earth days and is 1.5 times the size of Earth and three times as massive. They're both considered "rocky."

"Both planets in this system are each considered among the best targets for atmospheric study because of the brightness of their star," Michelle Kunimoto of MIT's Kavli Institute for Astrophysics and Space Research and one of the discovery's lead scientists, said in a statement.

That includes studies that aim to answer questions like, "Is there a volatile-rich atmosphere around these planets? And are there signs of water or carbon-based species?" Kunimoto said -- in other words, a protective layer like the Earth's ozone layer, and living beings like ... humans. "These planets are fantastic test beds for those explorations."

OK, but before you get too excited, the team emphasized that the newly unveiled rocky worlds of interest probably aren't habitable -- they tread really (really) close to their host star, so they're likely too hot to host water. The inner planet, per the study, roasts at an estimated 818 degrees Fahrenheit, and the other runs a balmy temperature of 548 degrees Fahrenheit.

"We consider that range outside the habitable zone," Kunimoto said.

Still, these worlds could prove invaluable for the overall quest to find habitable exoplanets. In short, they could inform how scientists conduct future studies that might come across planets which are in a habitable zone.

"But there might be more planets in the system," Shporer added. "There are many multiplanet systems hosting five or six planets, especially around small stars like this one. Hopefully we will find more." And if the team does find more, "maybe one might be in the habitable zone.

"That's optimistic thinking."

TSMC Reveals 2nm Node: 30% More Performance by 2025:

Taiwan Semiconductor Manufacturing Co. today officially introduced its N2 (2nm class) manufacturing technology, its first node that will use gate-all-around field-effect transistors (GAAFETs), at its 2022 TSMC Technology Symposium. The new fabrication process will offer a [full node's] performance and power benefits, but when it comes to transistor density, it will barely impress in 2025 when it comes online.

Being an all-new process technology platform, TSMC's N2 brings in two essential innovations: nanosheet transistors (which is what TSMC calls its GAAFETs) and backside power rail that both serve the same goal of increasing performance-per-watt characteristics of the node. GAA nanosheet transistors feature channels surrounded by gates on all four sides, which reduces leakage; furthermore, their channels can be widened to increase drive current and boost performance or shrunken to minimize power consumption and cost. To feed these nanosheet transistors with enough power and now waste any of it, TSMC's N2 uses backside power delivery, which the foundry considers to be among the best solutions to fight resistances in the back-end-of-line (BEOL).

Indeed, when it comes to performance and power consumption, TSMC's nanosheet-based N2 node can boast of a 10% to 15% higher performance at the same power and complexity as well as a 25% to 30% lower power consumption at the same frequency and transistor count when compared to TSMC's N3E. However, the new node increases chip density by only around 1.1X compared to N3E.

  N2 vs N3E N3E vs N5 N3 vs N5 N5 vs N7
Speed Improvement @ Same Power 10% ~ 15% +18% +10% ~ 15% +15%

While it may not be all that surprising to SN readers, some data on "self driving" cars has now hit the big time, WaPo reports: https://www.washingtonpost.com/technology/2022/06/15/tesla-autopilot-crashes/

Tesla vehicles running its Autopilot software have been involved in 273 reported crashes over roughly the past year, according to regulators, far more than previously known and providing concrete evidence regarding the real-world performance of its futuristic features.

The numbers, which were published by the National Highway Traffic Safety Administration for the first time Wednesday, show that Tesla vehicles made up nearly 70 percent of the 392 crashes involving advanced driver-assistance systems reported since last July, and a majority of the fatalities and serious injuries — some of which date back further than a year. Eight of the Tesla crashes took place before June 2021, according to data released by NHTSA on Wednesday morning.

And 5 of 6 fatalities were linked with Tesla cars, the other was one of the competing Level 2 systems offered by other automakers.

WaPo continues,

The new data set stems from a federal order last summer requiring automakers to report crashes involving driver assistance to assess whether the technology presented safety risks. Tesla's vehicles have been found to shut off the advanced driver-assistance system, Autopilot, around one second before impact, according to the regulators.

The NHTSA order required manufacturers to disclose crashes where the software was in use within 30 seconds of the crash, in part to mitigate the concern that manufacturers would hide crashes by claiming the software wasn't in use at the time of the impact.
