[:es]Neanderthals may have trapped golden eagles 130,000 years ago[:]
[:es]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[:]
[:es]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[:]
[:es]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]Another major drug candidate targeting the brain plaques of Alzheimer’s disease has failed. What’s left?[:]
[:es]“Futile”—that’s the devastating label now attached to two highly anticipated clinical trials of a drug that targets β-amyloid, the neuron-killing protein fragment littering the brains of people with Alzheimer’s disease. Biogen in Cambridge, Massachusetts, and Eisai in Tokyo, the pharmaceutical partners developing the drug, called aducanumab, today announced their decision to halt a pair of…
