Engineers produce a fisheye lens that’s completely flat

By Jennifer ChuTo capture panoramic views in a single shot, photographers typically use fisheye lenses — ultra-wide-angle lenses made from multiple pieces of curved glass, which distort incoming light to produce wide, bubble-like images. Their spherical, multipiece design makes fisheye lenses inherently bulky and often costly to produce.Now engineers at MIT and the University of Massachusetts at Lowell have designed a wide-angle lens that is completely flat. It is the ...

Astronomers may have found a signature of life on Venus

By Jennifer Chu The search for life beyond Earth has largely revolved around our rocky red neighbor. NASA has launched multiple rovers over the years, with a new one currently en route, to sift through Mars’ dusty surface for signs of water and other hints of habitability.Now, in a surprising twist, scientists at MIT, Cardiff University, and elsewhere have observed what may be signs of life in the clouds of ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
