Cuanto más pulule, se arrastre y vuele es mejor para los seres humanos. Esta es la conclusión de un estudio publicado en "Nature". Más de 60 investigadores de varias universidades estaban involucrados, incluyendo la Universidad Técnica de Munich, el Instituto de Ciencias Vegetales de la Universidad de Berna y el Centro de Investigación del Clima y Biodiversidad Senckenberg en Frankfurt.

Pacific sea level predicts global temperature changes
The amount of sea level rise in the Pacific Ocean can be used to estimate future global surface temperatures, according to a new report led by University of Arizona geoscientists.
Based on the Pacific Ocean's sea level in 2015, the team estimates by the end of 2016 the world's average surface temperature will increase up to 0.5 F (0.28 C) more than in 2014.
In 2015 alone, the average global surface temperature increased by 0.32 F (0.18 C).
Urbanization affects diets of butterflies
A study led by researchers from the National University of Singapore (NUS) revealed that most tropical butterflies feed on a variety of flower types, but those that are 'picky' about their flower diets tend to prefer native plants and are more dependent on forests. These 'picky' butterflies also have wings that are more conspicuous and shorter proboscis. The reduction in native plants due to urbanisation affects the diet of such butterflies, and researchers suggest that intervention may be needed to manage their preferred flower resources.
Climate Change Is Altering Our National Parks Forever
If you’ve ever taken a camping trip, hiked up a forested mountain trail or simply gone bird watching in an American national park, I have bad news: climate change is increasingly putting our nation’s wilderness in danger. And with July 2016 officially declared the hottest month on the planet since recordkeeping began, matters are only poised to get worse.
Rising global temperatures and changing weather patterns are already having wide-reaching effects on these wild places. Nowhere is this more apparent than in areas that used to be thick with ice and snow.
Venus-like exoplanet might have oxygen atmosphere, but not life
The distant planet GJ 1132b intrigued astronomers when it was discovered last year. Located just 39 light-years from Earth, it might have an atmosphere despite being baked to a temperature of around 450 degrees Fahrenheit. But would that atmosphere be thick and soupy or thin and wispy? New research suggests the latter is much more likely.
Harvard astronomer Laura Schaefer (Harvard-Smithsonian Center for Astrophysics, or CfA) and her colleagues examined the question of what would happen to GJ 1132b over time if it began with a steamy, water-rich atmosphere.
Blue Cut Fire in California spreads quickly
The Blue Cut Fire, just outside of Los Angeles, is a quickly growing fire that is currently an imminent threat to public safety, rail traffic and structures in the Cajon Pass, Lytle Creek, Wrightwood, Oak Hills, and surrounding areas. An estimated 34,500 homes and 82,640 people are being affected by the evacuation warnings that have been issued.
