Asphalt-paved roads make up 45% of the surfaces in cities across the country, and asphalt roofs another 20%. Efforts are being made to change the materials we use in this construction, such as cooling asphalt, which is often lighter colored, so it doesn’t absorb as much heat. Other researchers are looking into how cooling asphalts can reduce urban heat island effects; Gentner and his team didn’t look at cooling asphalts, but he guesses that they “likely also have an effect on emissions by reducing asphalt surface temperatures and solar exposure.” … [Read more...] about When roads heat up during the summer, the asphalt poisons urban air

"In relation to the airport environment, unusual weather condition, and infrastructure limitations such as the absence of runway centerline lightings, absence of full touchdown zone lighting system, and poor ILS signal quality; it is recommended that the Calicut airport authority carefully examine aerodrome operations and devise appropriate safety measures, or consider the practicability of the improvement of the airport infrastructure, in order to mitigate the associated risks." … [Read more...] about Air India Express crash: A year earlier, an Etihad flight’s narrow escape at Kozhikode airport was a wake up call

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time. … [Read more...] about Explained | What is the 12-minute ad cap that TRAI is asking TV channels to follow?
To show that there are alternatives to hot asphalt, Lawrence Berkeley Lab, in California, currently has a showcase of “cool pavements” that are designed to reflect between 30% to 50% of the energy, compared to about 5% for conventional surfaces. On some days, according to Benjamin Mandel, a researcher with the Heat Island Group, the new coatings are 40 degrees Fahrenheit cooler than traditional counterparts. … [Read more...] about Using Different Colored Streets To Keep Our Cities Cool
