United States
Increasing Virus Growth Rate
With over 123,000 reported deaths to date, COVID-19 infections are continuing to surge in many parts of the United States. Covid Act Now is a multidisciplinary team of technologists, epidemiologists, health experts, and public policy leaders that work to provide disease intelligence and data analysis on COVID-19 in the U.S. Using a SEIR model widely adopted by epidemiologists to forecast infectious diseases, they estimate Massachusetts, New Jersey, and New York are the only three states on track to containing the virus. The states of Alabama, Arizona, Georgia, and Missouri are either actively experiencing an outbreak, at extreme risk of exponential growth of the virus, or have a low level of preparedness compared to international standards. The majority of states continue to be at risk of further outbreaks or are in a phase of controlled disease growth.
This map depicts COVID-19 data and risk level of all fifty states in the U.S. All COVID-19 updates will be displayed in a red box.

Mexico
Deadly Earthquake
A 7.4 magnitude earthquake struck southern Mexico Tuesday evening, killing at least six people. The earthquake hit near the Southern coast outside of Santa María Zapotitlán, about 90 miles from the state capital, Oaxaca City. The powerful quake triggered tsunami waves, power-outages, and hundreds of buildings were damaged near the epicenter and surrounding villages. Tremors from the earthquake were felt as far as Mexico City, nearly 700 miles away. There were reports of more than 1,570 aftershocks, including a 5.5 magnitude quake.

World
Mercury in the Deepest Depths
The results of two independent studies presented at the Goldschmidt Geochemistry Conference provided evidence that man-made mercury have polluted the deepest and most inaccessible places in the world’s oceans. Researchers from China and the U.S. used deep-sea vehicles to collect fauna samples from the Mariana Trench, the Yap Trench, and the Kermadec Trench. Isotopic fingerprints proved the mercury present in the samples came from the upper ocean. Before these studies, scientists thought the mercury pollution was only present in the first few hundred meters of the ocean, and even the research teams themselves were surprised by the results. Mercury is toxic to both humans and other animals, and has been linked to major environmental disasters.

Founded by outdoorsman Greg Kamradt, Terra Mano (“Earth by Hand” in Latin) is a California-based company specializing in handmade, bronze topographic relief maps. Using data collected from the U.S. Geological Survey and supplemented by the firsthand experience of hikers, athletes, and locals. Kamradt uses 3D printing to create an exact replica model of the subject site, which is then used to create a master mold. Molten bronze is poured into the mold to create the map. The cast bronze is both durable and long-lasting, and because the maps are handcrafted, no two, even of the same site, are exactly the same. It’s in the nature of bronze to oxidize as it is exposed to its environment (think of the Statue of Liberty), so if you prefer a bit more color in your cast you can allow it to, or even accelerate, patina. Terra Mano currently creates maps of several sites across the U.S. but is also open to custom creations, each one an intricate example of ancient art and modern technology coming together to create something beautiful.

Q: Spanning over 580,000 sq miles, the largest area of alpine permafrost can be found in which country?
A: China
Permafrost mostly occurs in the Arctic and subarctic areas but can exist at lower latitudes in areas of high elevations. This is known as Alpine permafrost and for an area to receive this title, temperature measurements taken below the ground surface layer have to be 0 °C or colder persistently for two or more years.
