WHY ARE CICADAS SUCH CLUMSY FLIERS? By Lindsey Konkel. October 18, 2017 at 6:30 am. Cicadas are great at clinging to tree trunks and making loud screeching sounds by vibrating their bodies. But these bulky, red-eyed insects aren’t so great at flying. The reason why may lie in the chemistry of their wings, a new study shows. One of the researchers behind this new finding was HERE’S HOW LIGHTNING MAY HELP CLEAN THE AIR Lightning may play an important role in clearing the air of pollutants. A storm-chasing airplane has shown that lightning can forge large amounts of oxidants.These chemicals cleanse the atmosphere by reacting with pollutants such as methane. Those reactions form molecules that dissolve in water or stick to surfaces. The molecules can then rain out of the air or stick to objects on the ground. WHY BIG NUTS ALWAYS RISE TO THE TOP A new experiment reveals, in a nutshell, why the largest particles in some mixtures gather at the top.

Not totally flooded by water, but not completely dry either, these in-between places rank among the richest ecosystems on Earth.

WHERE DO HUMANS COME FROM? Consider, Berger says, the crown jewel of early Homo fossils. Found in 1994, it consists of just an upper jaw and palate (part of the mouth).

October 18, 2017 at 6:30 am. Cicadas are great at clinging to tree trunks and making loud screeching sounds by vibrating their bodies. But these bulky, red-eyed insects aren’t so great at flying.

WHY BIG NUTS ALWAYS RISE TO THE TOP A new experiment reveals, in a nutshell, why the largest particles in some mixtures gather at the top. Large Brazil nuts are notorious for ending up at the top of packages of mixed nuts. That’s why scientists call this phenomenon the Brazil nut effect. But it also occurs in cereal boxes, where larger pieces tend to collect on top. WHY ARE CICADAS SUCH CLUMSY FLIERS? By Lindsey Konkel. October 18, 2017 at 6:30 am. Cicadas are great at clinging to tree trunks and making loud screeching sounds by vibrating their bodies. But these bulky, red-eyed insects aren’t so great at flying. The reason why may lie in the chemistry of their wings, a new study shows. One of the researchers behind this new finding was CHIMP’S GIFT FOR NUMBERS Ayumu the chimpanzee plays a number memory game faster and more accurately than any human player. T. Matsuzawa, Primate Research Institute Whatever you do, don’t challenge a chimpanzee named Ayumu to a number memory game.

Wingspans can exceed 7 centimeters (2.8 inches), not quite the full width of a woman’s palm. Workers are smaller. Such true hornets are big, predatory, colony-forming wasps. They belong to the genus Vespa. LIKE MAGNETO? MICROCRYSTALS GIVE MAGNETS SUPERPOWER OVER It would be a bit like Magneto, the supervillain in X-Men. He can control anything magnetic. Even the iron inside someone’s body. Controlling people with magnets sounds a little, well, wacky. But scientists have now done something close to that. They have engineered cells to make long, needle-like crystals rich in iron. MAILING OFF MY MICROBEADS The beads that give your face wash that gritty feeling are usually between 0.05 and 0.5 millimeters (one thousandth to one hundredth of an inch) in diameter. That span ranges from about the size of the tip of a needle to the tip of a ballpoint pen. These beads can be made of any of several common plastics.

WHY BIG NUTS ALWAYS RISE TO THE TOP A new experiment reveals, in a nutshell, why the largest particles in some mixtures gather at the top. Large Brazil nuts are notorious for ending up at the top of packages of mixed nuts. That’s why scientists call this phenomenon the Brazil nut effect. But it also occurs in cereal boxes, where larger pieces tend to collect on top. WHY ARE CICADAS SUCH CLUMSY FLIERS? By Lindsey Konkel. October 18, 2017 at 6:30 am. Cicadas are great at clinging to tree trunks and making loud screeching sounds by vibrating their bodies. But these bulky, red-eyed insects aren’t so great at flying. The reason why may lie in the chemistry of their wings, a new study shows. One of the researchers behind this new finding was CHIMP’S GIFT FOR NUMBERS Ayumu the chimpanzee plays a number memory game faster and more accurately than any human player. T.

Even the iron inside someone’s body. Controlling people with magnets sounds a little, well, wacky. But scientists have now done something close to that. They have engineered cells to make long, needle-like crystals rich in iron. MAILING OFF MY MICROBEADS The beads that give your face wash that gritty feeling are usually between 0.05 and 0.5 millimeters (one thousandth to one hundredth of an inch) in diameter. That span ranges from about the size of the tip of a needle to the tip of a ballpoint pen. These beads can be made of any of several common plastics. BRINGING COVID-19 VACCINES TO MUCH OF WORLD IS HARD Months before the first COVID-19 vaccine was even approved, wealthy nations scrambled to line up hundreds of millions of advance doses. These would go to their citizens and no others. By the end of 2020, Canada had bought 266 million doses. That was enough to vaccinate all its people four times over.The United Kingdom snagged three times what

its people needed.

These spaces include our cells and the cells of other living things. Second, because nanosilver particles are so small, they have very high surface areas. That means that relative to their volume, their surface is fairly big. FOR COUGHING UP PHLEGM, WATER IS KEY Normal mucus is 98 percent water. In people with cystic fibrosis, that mucus is only 79 percent water. Using the peel tester, the team showed that the force of a cough could easily tear normal phlegm off a surface. But at 79 percent water, mucus clung too tightly. A cough would not be strong enough to propel it out of the lung’s tiny

airways.
