Pulse oximeters measure the percentage of oxygen in the blood when clipped onto a fingertip. And according to HuffPost, they're becoming increasingly popular for home use. People are buying them to monitor a family member if he or she becomes seriously ill with COVID-19. Doctors praise the use of pulse oximeters because they can alert people who don’t realize they’re gravely ill to the fact that their body is struggling for oxygen. One of the biggest worries with COVID-19 is when someone doesn’t realize their oxygen levels have dropped because they don’t actually feel unwell. It's a phenomenon sometimes referred to as happy hypoxia or silent hypoxia. As a normal reading usually ranges from 95-100%, if your reading is under 95%, it's a red flag. Seek medical attention immediately.
During a briefing in Kyiv, Hans Kluge, the World Health Organization Europe regional director, warns of a "life-threatening" winter to come for millions of Ukrainians after a series of devastating Russian attacks on the country's energy infrastructures. This winter will be "a formidable test for the Ukraine health system and the Ukraine people," he adds. SOUNDBITE
Puntarenas province, Costa Rica, Jan 13 (EFE).- Artificial coral reefs are proving key to the recovery of marine life in Costa Rica, helping to maintain a diversity of fish communities, prevent erosion and serve as part of a broader protective corridor.One of these reef projects is located at Playa Blanca, a beach in the Pacific province of Puntarenas that has earned a five-starred Blue Flag for its clean water and outstanding environmental management.A total of 14 bell-shaped artificial reef structures weighing between 250 and 600 kilograms have been installed there and currently are serving as habitat for a wide range of marine species.

Scientists have discovered the largest species that has the ability to regrow limbs. According to Business Insider, it's the alligator. Like lizards, young American gators can regrow their tails up to 9 inches. Prof. Kenro Kusumi is a co-senior study author and the director of Arizona State University's School of Life Sciences. Kusumi began studying gator regrowth after receiving a package in the mail that contained a deformed alligator tail in a pickle jar with ethanol. The tail was discolored, forked, and the scales were smaller than normal. Kusumi realized that the tail looked like it had been regrown.
Marine life uses sound to hunt, avoid predators, and find mates. But if their sounds are drowned out by engines, species can be affected dramatically. Even as the oceans are getting noisier, we're still basically unaware of the full toll it takes on ocean life. Gizmodo reports decreased human activity has given researchers an unprecedented chance to study the effect of quiet on our typically noisy seas. Wildlife biologist Chris Gabriele says the waters around Glacier Bay, Alaska, have seen median daily sound levels decrease by 50% between 2019 and 2020. As a result, she’s seen humpback whales hanging out in much broader swaths of the region, socializing, feeding, napping, and 'chatting' with each other.
With no end in sight to the novel coronavirus COVID-19 pandemic in the US, it's no surprise that myths about the virus abound. According to Business Insider, one common myth is that wearing a mask is dangerous because you'll get carbon dioxide poisoning. But epidemiology professor Stephen Morse says any CO2 the wearer exhales passes through the mask, just like oxygen, and doesn't build up. After all, healthcare workers wear masks for hours on end, which is proof that mask-wearing does not cause carbon dioxide poisoning or toxicity. Furthermore, blood oxygen levels remain perfectly normal when wearing a mask, provided the wearer is healthy.
