Tech Xplore / Reprogrammable shape morphing of magnetic soft machines
Shape-morphing magnetic soft machines have diverse applications in minimally invasive medicine, wearable devices and soft robotics. However, most magnetic programming approaches are inherently coupled to the fabrication processes, ...
Phys.org / NASA observations aid efforts to track California's wildfire smoke from space
Wildfires have been burning across the state of California for weeks—some of them becoming larger complexes as different fires merge. One of those was the August Complex Fire, which reportedly began as 37 distinct fires ...
Medical Xpress / Pets linked to maintaining better mental health and reducing loneliness during lockdown, new research shows
Sharing a home with a pet appeared to act as a buffer against psychological stress during lockdown, a new survey shows.
Medical Xpress / Study reveals design flaws of chatbot-based symptom-checker apps
Millions of people turn to their mobile devices when seeking medical advice. They're able to share their symptoms and receive potential diagnoses through chatbot-based symptom-checker (CSC) apps.
Tech Xplore / Bolstering AI by tapping human testers
Advances in artificial intelligence depend on continual testing of massive amounts of data. This benchmark testing allows researchers to determine how "intelligent" AI is, spot weaknesses and then develop stronger, smarter ...
Medical Xpress / Study offers new details on pediatric mental health boarding
A Dartmouth-led study, published in the journal Pediatrics, offers new details about pediatric mental health boarding in emergency departments across the country, a problem that has steadily increased in the last 10 years ...
Phys.org / Diagnostic tool for coronavirus makes significant step forward
Scientists at the University of Warwick have demonstrated that a potential diagnostic tool for detecting COVID-19 using sugars will work with a virus rather than just its proteins, a significant step in making it a viable ...
Phys.org / New method allows precise gene control by light
A novel optical switch makes it possible to precisely control the lifespan of genetic copies. These are used by the cell as building instructions for the production of proteins. The method was developed by researchers from ...
Phys.org / Provably exact artificial intelligence for nuclear and particle physics
The Standard Model of particle physics describes all the known elementary particles and three of the four fundamental forces governing the universe; everything except gravity. These three forces—electromagnetic, strong, ...
Phys.org / Astronomers model, determine how disk galaxies evolve so smoothly
Computer simulations are showing astrophysicists how massive clumps of gas within galaxies scatter some stars from their orbits, eventually creating the smooth, exponential fade in the brightness of many galaxy disks.
Phys.org / Physicists develop a method to improve gravitational wave detector sensitivity
Gravitational wave detectors have opened a new window to the universe by measuring the ripples in spacetime produced by colliding black holes and neutron stars, but they are ultimately limited by quantum fluctuations induced ...
Medical Xpress / Team assessing if dual-antibody injection prevents COVID-19 illness
A combination antibody treatment for preventing COVID-19 illness in individuals who have had sustained exposure to someone with the virus is being studied by researchers at The University of Texas Health Science Center at ...
