[:es]Evidence suggests life on Earth started after meteorites splashed into warm little ponds[:]
Life on Earth began somewhere between 3.7 and 4.5 billion years ago, after meteorites splashed down and leached essential elements into warm little ponds, say scientists at McMaster University and the Max Planck Institute in Germany. Their calculations suggest that wet and dry cycles bonded basic molecular building blocks in the ponds’ nutrient-rich broth into…

El ADN de las bacterias ha sido alterado para combatir un trastorno desde dentro del cuerpo. Forman parte de la nueva rama de los bióticos sintéticos, cuyo objetivo es actuar como fármacos vivos, pero también podrían servir para producir otros productos químicos para combustibles y perfumes, entre otros

[:es]Private companies are launching a new space race – here’s what to expect[:]
The space race between the USA and Russia started with a beep from the Sputnik satellite exactly 60 years ago (October 4, 1957) and ended with a handshake in space just 18 years later. The handshake was the start of many decades of international collaboration in space. But over the past decade there has been…

[:es]What artificial brains can teach us about how our real brains learn[:]
Studying the human mind is tough. You can ask people how they think, but they often don’t know. You can scan their brains, but the tools are blunt. You can damage their brains and watch what happens, but they don’t take kindly to that. So even a task as supposedly simple as the first step…
