[:es]Scientists tackle a burning question: When will our quiet sun turn violent?[:]
For all of February the sun is nearly spotless, a smooth circle filled in with a goldenrod crayon. It has been more than a decade since it was so lacking in sunspots—dark magnetic knots as big as Earth that are a barometer of the sun’s temperament. Below the surface, however, a radical transition is afoot.…

[:es]A solution to psychology’s reproducibility problem just failed its first test[:]
Behavior change is difficult—just ask any psychologist. A new study shows behavior change among psychologists is no different. Efforts to improve the robustness of research by asking psychologists to state their methods and goals ahead of time, a process called preregistration, have stumbled at the first hurdle.

[:es]‘Wood wide web’—the underground network of microbes that connects trees—mapped for first time[:]
Trees, from the mighty redwoods to slender dogwoods, would be nothing without their microbial sidekicks. Millions of species of fungi and bacteria swap nutrients between soil and the roots of trees, forming a vast, interconnected web of organisms throughout the woods. Now, for the first time, scientists have mapped this “wood wide web” on a…

[:es]Viruses genetically engineered to kill bacteria rescue girl with antibiotic-resistant infection[:]
One week after Helen Spencer’s 15-year-old cystic fibrosis patient had a double lung transplant in September 2017, the incision wound turned bright red. For half her life, Isabelle Carnell had been battling a drug-resistant infection of Mycobacterium abscessus, and now it was rapidly spreading, erupting in weeping sores and swollen nodules across her frail body.…

[:es]Theorist calculates the incalculable siren song of merging black holes[:]
Just a month into a renewed observing campaign with a trio of detectors, physicists today announced they have spotted more gravitational waves—fleeting ripples in space set off when two massive objects such as black holes spiral into each other. The collaboration has now bagged 13 merging black hole pairs, as well as two pairs of…

[:es]Neanderthals may have trapped golden eagles 130,000 years ago[:]
The golden eagle has been hunted and revered by human cultures for thousands of years. Yet this may not have been a uniquely human devotion—Neanderthals, too, may have targeted these impressive birds of prey some 130,000 years ago, according to new research. What’s more, modern humans may have learned their eagle-catching techniques from their hominin…

[:es]Emperor penguins flee unsteady ice after ‘unprecedented’ failure to breed[:]
Antarctica’s charismatic emperor penguins are thought to be particularly vulnerable to climate change, because warming waters are melting the sea ice where they live and breed. Now, the penguins have abandoned one of their biggest colonies after breeding pairs there failed to raise almost any new chicks in 3 years. Although the move cannot directly…

[:es]Global warming may boost economic inequality[:]
Over the past half-century, climate change has been blamed for heat waves, flooding, and rising seas. Now, researchers say warmer temperatures are widening the chasm separating richer and poorer countries, effectively boosting the economies of many wealthy polluters while dampening growth in much of the developing world. As a result, inequality between the haves and…

[:es]New climate models predict a warming surge[:]
For nearly 40 years, the massive computer models used to simulate global climate have delivered a fairly consistent picture of how fast human carbon emissions might warm the world. But a host of global climate models developed for the United Nations’s next major assessment of global warming, due in 2021, are now showing a puzzling…
