Disadvantaged people wait significantly longer for power restoration after major storms, research shows      (via sciencedaily.com)     Original source 

Researchers sought to investigate whether socioeconomically vulnerable households experienced longer power outage durations after extreme weather events. The team analyzed data from the top eight major Atlantic hurricanes between 2017 and 2020 that knocked out power for over 15 million customers in nine states across the southeastern U.S. The team found that people in lower socioeconomic tiers wait significantly longer to have power restored after a major storm -- nearly three hours longer on average.

AI study reveals individuality of tongue's surface      (via sciencedaily.com)     Original source 

Artificial Intelligence (AI) and 3D images of the human tongue have revealed that the surface of our tongues are unique to each of us, new findings suggest. The results offer an unprecedented insight into the biological make-up of our tongue's surface and how our sense of taste and touch differ from person to person.

Thinking about God inspires risk-taking for believers, study finds      (via sciencedaily.com)     Original source 

Does thinking about faith make religious people more likely to take leaps? A new study says yes, finding that participants were more likely to take risks when thinking about God as a benevolent protector.  The study specifically looked at American Christians and 'morally neutral' risks.

U.S. renters are hit the hardest when a hurricane strikes, new research shows      (via sciencedaily.com)     Original source 

Two new studies based on data from 2009 to 2018 show that renters living along the East and Gulf coasts of the United States face rent increases, higher eviction rates, and a lack of affordable housing in the aftermath of a hurricane.

Unexpected chemistry reveals cosmic star factories' secrets      (via sciencedaily.com)     Original source 

Two galaxies in the early universe, which contain extremely productive star factories, have been studied by a team of scientists. Using powerful telescopes to split the galaxies' light into individual colors, the scientists were amazed to discover light from many different molecules -- more than ever before at such distances. Studies like this could revolutionize our understanding of the lives of the most active galaxies when the universe was young, the researchers believe.

This next generation blue light could potentially promote or hinder sleep on command      (via sciencedaily.com)     Original source 

Blue light from LED lamps and consumer electronics can mess with your sleep because it disrupts production of the natural sleep hormone melatonin. Tinted glasses or displays in night mode can mask, but don't remove, a portion of the disruptive wavelengths. But now, researchers report that they have designed more 'human-centric' LEDs that could potentially enhance drowsiness or alertness on command.

Upcycling leftover cardboard to make a new type of foam packaging      (via sciencedaily.com)     Original source 

With the holiday season in full swing, gifts of all shapes and sizes are being shipped around the world. But all that packaging generates lots of waste, including cardboard boxes and plastic-based foam cushioning. Rather than discard those boxes, researchers have developed a cushioning foam from cardboard waste. Their upcycled material was stronger and more insulating than traditional, plastic foam-based cushioning.

Researchers find way to weld metal foam without melting its bubbles      (via sciencedaily.com)     Original source 

Researchers have identified a welding technique that can be used to join composite metal foam (CMF) components together without impairing the properties that make CMF desirable. CMFs hold promise for a wide array of applications because the pockets of air they contain make them light, strong and effective at insulating against high temperatures.

Gut bacteria of malnourished children benefit from key elements in therapeutic food      (via sciencedaily.com)     Original source 

New research has identified key, naturally occurring biochemical components of a novel therapeutic food that is aimed at repairing malnourished children's underdeveloped gut microbiomes. The study also has identified the important bacterial strains that process these biochemical components. The findings may help guide treatment with a current food formulation and enable creation of new, more effective formulations in the future.

Tiniest free-floating brown dwarf      (via sciencedaily.com)     Original source 

Brown dwarfs are objects that straddle the dividing line between stars and planets. They form like stars, growing dense enough to collapse under their own gravity, but they never become dense and hot enough to begin fusing hydrogen and turn into a star. At the low end of the scale, some brown dwarfs are comparable with giant planets, weighing just a few times the mass of Jupiter.

Interactive screen use reduces sleep time in kids      (via sciencedaily.com)     Original source 

While screen time is generally known to affect sleep, new research suggests that interactive engagement, such as texting friends or playing video games, delays and reduces the time spent asleep to a greater extent than passive screen time, like watching television -- especially for teens.
