A prototype by Kratos was first to fly, but Boeing and General Atomics will also develop Skyborg air vehicles.
Many people with diabetes endure multiple, painful finger pricks each day to measure their blood glucose. Now, researchers reporting in ACS Sensors have developed a device that can measure glucose in sweat with the touch of a fingertip, and then a personalized algorithm provides an accurate estimate of blood glucose levels.
According to the American Diabetes Association, more than 34 million children and adults in the U.S. have diabetes. Although self-monitoring of blood glucose is a critical part of diabetes management, the pain and inconvenience caused by finger-stick blood sampling can keep people from testing as often as they should.
The researchers made a touch-based sweat glucose sensor with a polyvinyl alcohol hydrogel on top of an electrochemical sensor, which was screen-printed onto a flexible plastic strip. When a volunteer placed their fingertip on the sensor surface for 1 minute, the hydrogel absorbed tiny amounts of sweat. Inside the sensor, glucose in the sweat underwent an enzymatic reaction that resulted in a small electrical current that was detected by a hand-held device.
The release of the new Go FlyEase felt more exclusive than inclusive. Now, disabled people are voicing their concerns with how the sneaker was handled.

Summary: Almost fifty percent of people who have children with partners suffering from schizophrenia or bipolar disorder also have mental health challenges, a new study reports.

Almost half of the parents who have children together with a parent with schizophrenia or bipolar disorder, are themselves burdened by psychological issues. This can affect family life and the children. This is shown in the research result from the major Danish psychiatry project iPSYCH.
Coal is a highly polluting and expensive way to generate electricity. This analysis shows that we have economic alternatives to continuing to burn coal for power in the US. Furthermore, analyses such as “The 2035 Report” show that we can fully retire coal, stop building other fossil fuel plants (namely gas), and still reliably meet electricity demand, while providing a host of environmental and societal benefits. There are existing policies that can help policymakers closely examine the cost burden of generation resources used today, procure cheaper and cleaner generation resources going forward, and address current assets on the books. The continuation and intensification of the coal cost crossover demands attention from policymakers and consumers alike.
The costs of most existing US coal-fired power plants are now more expensive than the total costs of wind and solar.
Researchers have discovered a group of soil bacteria that could yield alternatives to conventional fertilizers for enriching soil and improving crop yields.
A team of researchers from the Boyce Thompson Institute (BTI) has discovered a distinct group of bacteria that may help fungi and plants acquire soil nutrients. The findings could point the way to cost-effective and eco-friendly methods of enriching soil and improving crop yields, reducing farmers’ reliance on conventional fertilizers.
Researchers know that arbuscular mycorrhizal (AM) fungi establish symbiotic relationships with the roots of 70% of all land plants. In this relationship, plants trade fatty acids for the fungi’s nitrogen and phosphorus. However, AM fungi lack the enzymes needed to free nitrogen and phosphorus from complex organic molecules.
“This work confirms that there is a link between air pollution and how well the aging brain works,” senior study author and Columbia University researcher Andrea Baccarelli told The Guardian. “These shorter-term effects are reversible: when air pollution clears, our brain reboots and starts working back to its original level. However, multiple occurrences of these higher exposures cause permanent damage.”
Thankfully, it’s reversible.
Needless to say, DNA is the “instructions” via which our genes are transferred between us and our offspring. And RNA is in charge of regulating the production of proteins in a body, and its so-called “instructions” that it gives are for cellular structure.
To be clear: RNA and DNA serve different functions, and, as the Centers for Disease Control and Prevention (CDC) explains, mRNA vaccines don’t affect or even interact with our DNA at all.
In this week’s Pandemic Problems column, a reader asks how to explain mRNA vaccines to a worried family member.
The team went so far as to say that “black fungi-bacteria-like specimens also appeared atop the rovers.”
They didn’t stop there: the team also examined photos taken by NASA’s HiRISE, and found evidence for “amorphous specimens within a crevice” that “changed shape and location then disappeared.”
“It is well established that a variety of terrestrial organisms survive Mars-like conditions,” the team concludes. “Given the likelihood Earth has been seeding Mars with life and life has been repeatedly transferred between worlds, it would be surprising if there was no life on Mars.”
