Airglow is the constant, faint glow of Earth’s upper atmosphere created by the interaction between sunlight and particles in this region. The phenomenon is similar to auroras, but where auroras are driven by high-energy particles originating from the solar wind, airglow is energized by ordinary, day-to-day solar radiation.
Studying airglow gives scientists clues about the upper atmosphere’s temperature, density, and composition, and helps us trace how particles move through the region itself. Two NASA missions take advantage of our planet’s natural glow to study the upper atmosphere: ICON focuses on how charged and neutral gases in the upper atmosphere interact, while GOLD observes what’s driving change — the Sun, Earth’s magnetic field or the lower atmosphere — in the region.
By watching and imaging airglow, the two missions enable scientists to tease out how Earth’s weather and space intersect, dictating the region’s complex behavior. https://go.nasa.gov/2RJax4x
Temporary tattoo electrodes are the most recent development in the field of cutaneous sensors. They have successfully demonstrated their performances in the monitoring of various electrophysiological signals on the skin. These epidermal electronic devices offer a conformal and imperceptible contact with the wearer while enabling good quality recordings over time. Evaluations of brain activity in clinical practice face multiple limitations, where such electrodes can provide realistic technological solutions and increase diagnostics efficiency. Here we present the performance of inkjet-printed conducting polymer tattoo electrodes in clinical electroencephalography and their compatibility with magnetoencephalography. The working mechanism of these dry sensors is investigated through the modeling of the skin/electrode impedance for better understanding of the biosignals transduction at this interface. Furthermore, a custom-made skin phantom platform demonstrates the feasibility of high-density recordings, which are essential in localizing neuropathological activities. These evaluations provide valuable input for the successful application of these ultrathin electronic tattoos sensors in multimodal brain monitoring and diagnosis.
Other researchers who were not involved in the project pointed out that plenty of work still has to be done to eventually be able to connect it to the human visual system, as Scientific American reports.
But some are hopeful.
“I think in about 10 years, we should see some very tangible practical applications of these bionic eyes,” Hongrui Jiang, an electrical engineer at the University of Wisconsin–Madison who was not involved in the research, told Scientific American.
More than 100,000 coronavirus cases have been reported to the World Health Organization in the last 24 hours, “the most in a single day since the outbreak began,” director-general Dr. Tedros Adhanom Ghebreyesus, said at a news conference Wednesday.
“We still have a long way to go in this pandemic,” he said. “In the last 24 hours, there have been 106,000 cases reported to WHO — the most in a single day since the outbreak began.”
Tedros added that almost “two-thirds of these cases were reported in just four countries,” although he did not specify where the cases had been recorded.

Cerebral palsy is a condition that results from injuries or abnormalities of the brain, usually in the womb but occurring any time during 2 years after birth. It affects brain and nervous system functions such as thinking, seeing, hearing, learning and movement.
Physicists at the National Institute of Standards and Technology have boosted their control of the fundamental properties of molecules at the quantum level by linking or “entangling” an electrically charged atom and an electrically charged molecule, showcasing a way to build hybrid quantum information systems that could manipulate, store and transmit different forms of data.
Described in a Nature paper posted online May 20, the new NIST method could help build large-scale quantum computers and networks by connecting quantum bits (qubits) based on otherwise incompatible hardware designs and operating frequencies. Mixed-platform quantum systems could offer versatility like that of conventional computer systems, which, for example, can exchange data among an electronic processor, an optical disc, and a magnetic hard drive.
The NIST experiments successfully entangled the properties of an electron in the atomic ion with the rotational states of the molecule so that measurements of one particle would control the properties of the other. The research builds on the same group’s 2017 demonstration of quantum control of a molecule, which extended techniques long used to manipulate atoms to the more complicated and potentially more fruitful arena offered by molecules, composed of multiple atoms bonded together.
Here’s one we missed from several months ago: Brazilian eVTOL innovator EmbraerX put forth a fun video showing how a multi-mode 3D transport system might work, with an eVTOL air taxi carrying a detachable glassed-over cabin that it delivers straight onto a self-driving car chassis.
The coming new breed of eVTOL air taxis are nearly all, at this stage, designed to work as part of a multi-mode transport scheme. The flying taxis themselves will travel from skyport to skyport, meaning you’ll need other means to get yourself to the takeoff point and something else again at the other end for the last mile. It’s simply not practical to expect eVTOLs to drop you off right at your destination.

After biomedical scientists demonstrated that they could make dangerous viruses like influenza even more dangerous, the National Institutes of Health (NIH) implemented a three-year moratorium on funding such research. But a couple of months ago, in December, the moratorium was lifted, and a tight set of rules were put in its place, such as a mandate for oversight panels.
The prospect of engineering a deadly pandemic virus in a laboratory suggests that only a fool would wish away government regulation entirely.
However, as a whole, regulation has done more harm than good in the arena of scientific innovation. The reason is that the sort of person who thinks like a bureaucratic regulator isn’t the sort of person who thinks like a scientist. The sad fact of the matter is that those most interested in the regulatory process tend to be motivated by politics and ideology rather than scientific inquiry and technological progress.
