An anonymous reader quotes a report from IEEE Spectrum: New circuits can get printed directly on human skin to help monitor vital signs, a new study finds. In the new study, researchers developed a way to sinter nanoparticles of silver at room temperature. The key behind this advance is a so-called a sintering aid layer, consisting of a biodegradable polymer paste…

Hummingbirds can drop their body temperature below 4°C when they rest
Hummingbirds are one of a few species that can enter a hibernation-like state to preserve energy, but now researchers have seen them reaching extremely low body temperatures Source: https://www.newscientist.com/article/2254001-hummingbirds-can-drop-their-body-temperature-below-4c-when-they-rest/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
What are brown dwarfs?

Scientists Trigger Hibernation In Mice, Could Astronauts Be Next?
“Scientists in Japan successfully triggered a hibernation-like state in mice by activating a specific group of brain cells,” reports UPI, which points out that entering a hibernation-like state “could help astronauts conserve food and water, as well as avoid the ill-effects of microgravity, on long journeys through space.”
The research, published this week in the journal Nature, suggests even animals that don’t…
Wolf spiders may turn to cannibalism in a warming Arctic

Boston Dynamics Open-Sources Health Care Robotics Toolkit, Sends ‘Spot’ Robot To Help Hospitals Remotely Treat COVID-19 Patients
watha2020 writes: Spot, the four-legged robot made famous by its YouTube dance video, is being tested as a remote triage system at Boston’s Brigham Women’s Hospital. A Spot robot carrying an iPad allows doctors to interview possibly infected patients at a safe distance. [Spot is also carrying a pouch near the robot’s “tail,” which allows it to deliver small items such…
What It’s Like To Attend a Conference — in Person — in the Age of Covid-19?
What happens when no one shows up for a tech conference? Fast Company’s technology editor harrymcc writes:
From Apple to Microsoft to Google, major tech companies have responded to the coronavirus crisis by either canceling their 2020 conference or making them purely virtual. But one well-established event — Vancouver’s CanSecWest — went ahead earlier this month, with streaming as an option but…
Eggshells support idea that dinosaurs were warm-blooded
Were dinosaurs warm-blooded or cold-blooded? According to a new study that analyzed the chemistry of dinosaur eggshells, the answer is “warm”. Source: https://earthsky.org/earth/eggshells-suggest-dinosaurs-warm-blooded…
Early Riser or Night Owl? New Study May Help To Explain the Difference
Some people are early risers, wide awake at the crack of dawn. Others are night owls who can’t seem to get to bed until well after midnight and prefer to sleep in. Why is this? An NIH-funded team has some new clues based on evidence showing how a molecular “switch” wired into the biological clocks of extreme early risers leads them…
98.6 Degrees Fahrenheit Isn’t the Average Anymore
schwit1 shares a report from The Wall Street Journal: Nearly 150 years ago, [German physician Carl Reinhold August Wunderlich] analyzed a million temperatures from 25,000 patients and concluded that normal human-body temperature is 98.6 degrees Fahrenheit. In a new study, researchers from Stanford University argue that Wunderlich’s number was correct at the time but is no longer accurate because the human…
