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.
From Italy:
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.
From Antarctica:
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.
From Iraq:
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.
From Japan:
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.
From Kenya:
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.

大家好，我是《科学美国人》助理新闻编辑莎拉·莱温·弗雷西尔。下面是本杂志2020年7月刊的一篇短文，摘自“进展：科学、技术和医学前沿快报”版块。
这篇文章名为《要闻快讯》，汇集了全球各地非新冠病毒报道的摘要。
特克斯和凯科斯群岛：
人们通过分析2017年飓风“厄玛”和飓风“玛利亚”前后以及18个月后收集的变色龙发现，幸存的蜥蜴及其后代的脚掌更大也更有抓握力。研究团队检查了博物学收集的蜥蜴照片和70年的飓风数据，以证实这一趋势。
意大利：
从第勒尼安海采集的沉积物样本揭示出热点，每平方米沉积物中含有多达190万微塑料分子，这是有记录以来海底的最高浓度。研究人员表示，大多数污染物来自下水道系统的废水。
南极洲：
古生物学家在南极半岛尖端附近的西摩岛上发现了4000万年前的青蛙化石。这只青蛙与现在生活在智利安第斯山脉温和潮湿环境中的现代青蛙有亲缘关系。
伊拉克：
研究人员在调查土耳其国家档案时发现了已知最早的陨石致死记录。1888年，这个物体撞击了邻国伊拉克的一座山顶，致一人死亡，另一人瘫痪。
日本：
从神冈天文台（该机构拥有注满5.5万吨水的地下探测罐）收集的结果显示，中微子和反中微子的振荡方式存在着有趣的差异，这可能会破坏物质和反物质之间的对称性。
肯尼亚：
科学家在维多利亚湖畔的蚊子体内发现了阻止疟疾的细菌。每只被这种明显是良性真菌分类的蚊子，都没有携带疾病的寄生虫，而且实验表明这种真菌阻止了传播。
以上是《要闻快讯》，我是莎拉·莱温·弗雷泽。
