Here are some brief reports about science and technology from all over, including one about how a lizard population responded to hurricanes by developing larger and stickier toe pads on average.
Hi, I’m Scientific American assistant news editor Sarah Lewin Frasier. And here’s a short piece from the July 2020 issue of the magazine, in the section called Advances: Dispatches from the Frontiers of Science, Technology and Medicine.
The article is titled “Quick Hits,” and it’s a rundown of some noncoronavirus stories from around the globe.
From Turks and Caicos Islands:
Analysis of anole lizards collected before and after Hurricanes Irma and Maria in 2017, and 18 months later, revealed that the surviving lizards and their descendants had larger and therefore “grippier” toe pads. The team examined lizard photographs from natural history collections and 70 years of hurricane data to confirm the trend.
Sediment samples drawn from the Tyrrhenian Sea revealed hotspots with up to 1.9 million microplastic particles per square meter—the highest concentration ever recorded on the seafloor. Most of this pollution comes from wastewater in sewage systems, researchers say.
Paleontologists found a fossilized 40-million-year-old frog on Seymour Island, near the tip of the Antarctic Peninsula. The frog is related to modern ones living in temperate, humid conditions in the Chilean Andes.
Researchers probing the Turkish state archives found the earliest known record of a meteorite causing a death. The object struck a hilltop in neighboring Iraq in 1888, killing one man and paralyzing another.
Results gathered from the Kamioka Observatory, which includes an underground detector tank filled with 55,000 tons of water, suggest an intriguing discrepancy in how neutrinos and antineutrinos oscillate, potentially violating symmetry between matter and antimatter.
Scientists identified a malaria-blocking microbe in mosquitoes on the shores of Lake Victoria. Every mosquito catalogued with this apparently benign fungus was free of the disease-carrying parasite, and experiments show the fungus prevented its transmission.
That was Quick Hits. I’m Sarah Lewin Frasier.
