Country Hurricane Michael became a monster overnight, undergoing at least three periods of “rapid intensification” on its march toward Florida. Although meteorologists can predict a hurricane’s path with relative certainty, forecasting changes in intensity is more challenging, because of the complicated underlying physics and the difficulty of collecting data. Researchers are concerned that warmer ocean waters due to climate change will further complicate these observations, opening the door to hurricanes of greater intensity and unpredictability.‘We are headed for a very dark period.’ Brazil’s researchers fear election of far-right presidential candidateBrazil appears poised to elect a far-right candidate, Jair Bolsonaro, as its next president. His rapid ascent has unnerved local researchers, who worry about the future of Brazilian science, protection of the country’s biodiversity, and Brazil’s role in the global struggle against climate change. Bolsonaro has vowed to withdraw Brazil from the 2015 Paris agreement and plans to eliminate the country’s Ministry of the Environment.Can you guess the ages of these faces?Humans are awful at estimating a person’s age based on their face alone. New research shows people are usually off by about 8 years, and their estimate might be shaped by the last face they saw.A revolutionary treatment for allergies to peanuts and other foods is going mainstream—but do the benefits outweigh the risks?More than 3000 people worldwide, most of them children, have undergone peanut immunotherapy for a peanut allergy, with the goal of protecting them if they accidentally encounter the food. Two biotechnology companies are racing to introduce a peanut-based capsule or patch, and both plan to apply for approval from the Food and Drug Administration this year. Although the breakthrough is cause for celebration among many families, physicians fret about the therapy’s rigors—treatment must continue indefinitely—and its risks, which sometimes include the same allergic reactions it aims to prevent.last_img read more
