Researchers investigated how solar reflective coatings on select Los Angeles city streets affected radiant heat and, in turn, pedestrians' comfort on a typical summer day. The idea is, if you coat a street with a lighter color than traditional pavement black, it will actually lower the surrounding temperatures. But researchers wanted to measure what effect reflective coating had on pedestrians.

New research has found that El Niño events are often associated with droughts in some of the world's more vulnerable tropical regions. Associated with warmer than average ocean temperatures in the eastern Pacific, El Niños can in turn influence global weather patterns and tropical precipitation, and these changes can lead to massive plant die-offs if other extreme factors are also at play.

Despite climate change affecting the entire planet's surface, areas of the Southern Ocean have bucked the trend. New research explains why. Since the middle of the 19th century, the average global temperature recorded on the land surface has risen by around one degree centigrade (1.8 degrees F), and by 0.6 degrees (0.054 degrees F) across the ocean surface. Global warming has been most pronounced

Evidence from a large study of several thousand patients in 11 European countries shows that men have higher concentrations of angiotensin-converting enzyme 2 (ACE2) in their blood than women. Since ACE2 enables the coronavirus to infect healthy cells, this may help to explain why men are more vulnerable to COVID-19 than women.

Although the clinical symptoms of SARS, H1N1, MERS, EVALI, and COVID-19 may be nonspecific, some characteristic imaging findings are emerging, according to a new article.

Plant scientists have long known that crop yield is proportional to the dose of nitrogen fertilizer, but the increased use of fertilizers is costly and harmful to the environment. Until now, the underlying mechanisms by which plants adjust their growth according to the nitrogen dose has been unknown—a key finding that could help enhance plant growth and limit fertilizer use.

The phrase 'the uplift of the Tibetan Plateau' permeates the scientific literature, extending even into the realms of molecular phylogeny. It implies that this enormous and almost flat-surfaced portion of Earth's surface rose as a coherent entity, and that uplift was driven entirely by the collision and northward movement of India.

Some light-emitting diodes (LEDs) created from perovskite, a class of optoelectronic materials, emit light over a broad wavelength range. Scientists from the University of Groningen have now shown that in some cases, the explanation of this phenomenon is incorrect.

Lender says coronavirus will have 'material impact' on performance in 2020

Editor's Note: This article is part of Uncharted , a series about the world we're leaving behind, and the one being remade by the pandemic. In February 1958, Science Digest , inspired by the launch of Sputnik and the consequent hastening of the space race, asked a question that was both timely and absurd: What will space people look like? Consulting unnamed scientists, the magazine concluded that

As is often pointed out, the SARS-CoV2 virus is new, and therefore we have limited data on its characteristics, as well as the disease it causes, COVID-19. This complicates our modeling of what is likely to happen, and recommendations about best practices. But scientists around the world are busy studying this pandemic as it is occurring, and therefore our models and recommendations are evolving.

In late March, The Boston Globe published an editorial excoriating President Donald Trump over his handling of the coronavirus pandemic.
