Los Angeles is Painting Its Streets to Reduce Urban Heat
An estimated 10 percent of Los Angeles is covered in asphalt thanks to the city’s sprawling network of roads and parking lots. On sunny days, the heat retained by these paved surfaces can make neighborhoods feel far hotter than those in more rural areas — a phenomenon known as the “urban heat island effect.” Now, Los Angeles is experimenting with painting its pavement grey to help significantly lower temperatures.
NASA Look at Tropical Storm Pakhar in Infrared Light
NASA’s Aqua satellite passed over Tropical Storm Pakhar and gathered temperature data to determine the location of the most powerful storms within. Pakhar has triggered a number of warnings throughout the Philippines as the storm moves closer.
Philippines warnings include Public storm warning signal #1 for the Luzon provinces of Cagayan including Babuyan group of islands, Apayao, Ilocos Norte, Nueva Ecija, Pangasinan, Northern Quezon including Polillo island, and Camarines Norte. Public storm warning signal #2 is in effect for the Luzon provinces of Isabela, Aurora, Quirino, Kalinga, Mountain Province, Ifugao, Ilocos Sur, Benguet, Abra, La Union and Nueva Vizcaya.
Icy air reveals human-made methane levels higher than previously believed
In 2011 a team of researchers led by Vasilii Petrenko, an assistant professor of Earth and environmental sciences at the University of Rochester, spent seven weeks in Antarctica collecting and studying 2,000-pound samples of glacial ice cores that date back nearly 12,000 years. The ancient air trapped within the ice revealed surprising new data about methane that may help inform today’s policymakers as they consider ways to reduce global warming.
New wrapping material enables high quality bioimaging
A nanosheet made of organic polymers has been developed to prevent the drying and deforming of biological samples, thus enabling high-quality imaging under microscopes.
Be it cosmology or biology, the advancement of science largely relies on the advancement of measuring instruments and methodology. In the past couple of decades, scientists’ passion to see the invisible has vastly improved microscopes and other equipment resulting in high-resolution images, three-dimensional images, and longer recording times of biological samples. However, current setups do not prevent them from drying and deforming during observations, resulting in blurred images.
Recipe for Safer Batteries — Just Add Diamonds
While lithium-ion batteries, widely used in mobile devices from cell phones to laptops, have one of the longest lifespans of commercial batteries today, they also have been behind a number of recent meltdowns and fires due to short-circuiting in mobile devices. In hopes of preventing more of these hazardous malfunctions researchers at Drexel University have developed a recipe that can turn electrolyte solution — a key component of most batteries — into a safeguard against the chemical process that leads to battery-related disasters.
