Zara Patel, a professor of otolaryngology and head and neck surgery at Stanford University School of Medicine in California. “This is the first time that we have a biologic, molecular explanation regarding one factor of our innate immune response that appears to be limited by colder temperatures,” said rhinologist Dr. It turns out the cold air itself damages the immune response occurring in the nose. In what researchers are calling a scientific breakthrough, scientists behind a new study may have found the biological reason we get more respiratory illnesses in winter. So why do people get more colds, flu and now Covid-19 when it’s chilly outside? Yet germs are present year-round - just think back to your last summer cold. Terovesalainen/Adobe StockĪs respiratory viruses strain US health care systems, Biden administration tells states how it's ready to help Close up of arm and medical professional. Constant pollution that doesn't look bad is acceptable, small pollution that occasionally looks bad is unacceptable to the public.Doctor giving vaccine, flu or influenza shot to patient with injection needle. So waterways and flood waters are diverted straight to the ocean, which can't handle the load. In total, they are nature's open sewers, composting piles and septic tanks, they do the work because the ocean can't.īesides being unsightly and having unpleasant odors, they'll occasionally flood and spill their "pollution" into waterways causing blooms and fish kills, also against what the public perceives as "nature". Real wetlands are the bogs, swamps and deltas, they get oily sheens, foamy, they go anaerobic and kill wildlife and they release tons of methane and noxious gasses while sinking carbon. ![]() The "wetlands" being restored now are natural marshy areas allowed to flood by the cleanest streams so birds have nesting areas, not useful at all. Get used to those foamy oceans, rather than restoring real wetlands to capture biomatter before reaching the oceans, instead, phosphorus was targeted so the matter passed without a bloom. ![]() The reality of climate change: 10 myths busted.While watermelon snow has existed for millions of years, algal blooms thrive in warm weather, meaning we can probably expect to see more events like this as the climate changes. That, in turn, leads to more warming, more melting, and more algal blooming.Ī similar feedback process is driving more extreme algal blooms in oceans all over the world, resulting in surreal scenes like an invasion of sea foam in Spain and blue, bioluminescent "tears" clinging to China's coasts. The more ice that melts, the faster the algae can spread. The more heat the algae absorbs, the faster the surrounding ice melts. "Snow blossoms contribute to climate change," the team wrote in the Facebook post. "Because of the red-crimson color, the snow reflects less sunlight and melts faster. As a consequence, it produces more and more bright algae." According to the Ukrainian researchers, it’s easy for these blooms to kick off a runaway feedback loop of warming and melting. ![]() That's good for the algae but not great for the ice. In addition to their crimson hue, these pigments also absorb heat and protect the algae from ultraviolet light, allowing the organisms to bask in the summer sun's nutrients without risk of genetic mutations. The phenomenon's red color comes from carotenoids (the same pigments that make pumpkins and carrots orange) in the algae's chloroplasts. ![]()
