This artist's concept illustrates a hierarchical scheme for merging black holes. LIGO and Virgo recently observed a black hole merger with a final mass of 142 times that of the sun, making it the largest of its kind observed in gravitational waves to date. — courtesy LIGO/Caltech/MIT/R. Hurt (IPAC)
A ‘bang’ in LIGO and Virgo detectors signals most massive gravitational-wave source yet
By Jennifer ChuFor all its vast emptiness, the universe is humming with activity in the form of gravitational waves. Produced by extreme astrophysical phenomena, these reverberations ripple forth and shake the fabric of space-time, like the clang of a cosmic bell.Now researchers have detected a signal from what may be the most massive black hole merger yet observed in gravitational waves. The product of the merger is the first clear detection of an “intermediate-mass” black hole, with a mass between 100 and 1,000 times that of the sun.They detected the signal, which they have labeled GW190521, on May 21, 2019, with the National Science Foundation’s Laser Interferometer Gravitational-wave Observatory (LIGO), a pair of identical, 4-kilometer-long interferometers in the United States;...

Using four cameras mounted on a dog-like robot developed by Boston Dynamics, the researchers have shown that they can measure skin temperature, breathing rate, pulse rate, and blood oxygen saturation in healthy patients, from a distance of 2 meters. — Courtesy of the researchers
Robot takes contact-free measurements of patients’ vital signs
By Anne TraftonDuring the current coronavirus pandemic, one of the riskiest parts of a health care worker’s job is assessing people who have symptoms of COVID-19. Researchers from MIT, Boston Dynamics, and Brigham and Women’s Hospital hope to reduce that risk by using robots to remotely measure patients’ vital signs.The robots, which are controlled by a handheld device, can also carry a tablet that allows doctors to ask patients about their symptoms without being in the same room.“In robotics, one of our goals is to use automation and robotic technology to remove people from dangerous jobs,” says Henwei Huang, an MIT postdoc. “We thought it should be possible for us to use a robot to remove the health care worker from the risk of directly exposing themselves to the...

Facebook launches its new TikTok clone, Instagram Reels
WASHINGTON — Facebook Inc.’s Instagram photo-sharing app is launching its clone of TikTok in more than 50 countries. The new Instagram feature will let users record and edit 15-second videos with audio, and will let users add visual effects. Users will be able to share Reels with followers on Instagram in a dedicated section called Reels in Explore.It will be embedded into Instagram in the United States and elsewhere, the company announced on Wednesday. The announcement comes a week after Facebook CEO Mark Zuckerberg defended the company’s copycat strategies to US lawmakers during an antitrust hearing.The company has been testing Reels in Brazil since November and in France, Germany and India since earlier this summer.Facebook has a long tradition of cloning competitive services....

Deepfakes, explained
By Meredith SomersMIT NewsDeepfakes can be used to manipulate and threaten individuals and corporations. But with a better understanding of the technology, executives can take steps to protect themselves and their companies.In March 2019, the CEO of a UK-based energy firm listened over the phone as his boss — the leader of the firm’s German parent company — ordered the transfer of €220,000 to a supplier in Hungary.News reports would later detail that the CEO recognized the “slight German accent and the melody” of his chief’s voice and followed the order to transfer the money [equivalent to about $243,000] within an hour. The caller tried several other times to get a second round of money, but by then the UK executive had grown suspicious and did not make any more...

Siemens compressors selected for gas reservoir storage project with Saudi Aramco
BERLIN — Siemens Energy was selected to provide centrifugal compressor systems for Saudi Aramco’s Hawiyah Unaizah Gas Reservoir Storage (HUGRS) project. The plant includes a gas injection facility with a capacity of 1,500 million standard cubic feet per day (MMSCFD) (42,475,270 cubic meters per day, or m3/d) and a withdrawal facility capable of processing up to 2,000 MMSCFD (56,633,693 m3/d) of gas.Siemens Energy received the order from Samsung Engineering, who was awarded the engineering, procurement, and construction (EPC) contract for the entire project earlier this year.The project, located 162 miles (260 kilometers) east of Saudi Arabia’s capital, Riyadh, includes a plant that will take surplus pipelines gas in the winter months and inject it into an existing depleted field....

MIT team races to fill COVID-19-related ventilator shortage
By David L. ChandlerIt was clear early on in the unfolding COVID-19 pandemic that a critical need in the coming weeks and months would be for ventilators, the potentially life-saving devices that keep air flowing into a patient whose ability to breathe is failing.Seeing a potential shortfall of hundreds of thousands of such units, professor of mechanical engineering Alex Slocum Sr. and other engineers at MIT swung into action, rapidly pulling together a team of volunteers with expertise in mechanical design, electronics, and controls, and a team of doctors with clinical experience in treating respiratory conditions.They started working together nonstop to develop an inexpensive alternative and share what they learned along the way. The goal was a design that could be produced quickly...

A new system relies on short-range Bluetooth signals emitted from people’s smartphones to trace who they've been in contact with. These signals represent random strings of numbers, likened to “chirps” that other nearby smartphones can remember hearing, offering a way to find people who may have been in contact with people who have tested positive for COVID-19. — Photo courtesy Christine Daniloff, MIT
Bluetooth signals from your smartphone could automate COVID-19 contact tracing while preserving privacy
By Kylie FoyLincoln LaboratoryImagine you’ve been diagnosed as Covid-19 positive. Health officials begin contact tracing to contain infections, asking you to identify people with whom you’ve been in close contact. The obvious people come to mind — your family, your coworkers.But what about the woman ahead of you in line last week at the pharmacy, or the man bagging your groceries? Or any of the other strangers you may have come close to in the past 14 days?A team led by MIT researchers and including experts from many institutions is developing a system that augments “manual” contact tracing by public health officials, while preserving the privacy of all individuals.The system relies on short-range Bluetooth signals emitted from people’s smartphones. These signals represent...

Learning about AI: A hub of MIT resources for K-12 students
MIT Media LabIn light of the recent events surrounding Covid-19, learning for grades K-12 looks very different than it did a month ago. Parents and educators may be feeling overwhelmed about turning their homes into classrooms.With that in mind, a team led by Media Lab Associate Professor Cynthia Breazeal has launched aieducation.mit.edu to share a variety of online activities for K-12 students to learn about artificial intelligence, with a focus on how to design and use it responsibly.Learning resources provided on this website can help to address the needs of the millions of children, parents, and educators worldwide who are staying at home due to school closures caused by Covid-19, and are looking for free educational activities that support project-based STEM learning in an exciting...
