New tomb will make Chernobyl site safe for 100 years

Thirty years after the Chernobyl nuclear accident, there's still a significant threat of radiation from the crumbling remains of Reactor 4. But an innovative, €1.5 billion super-structure is being built to prevent further ...

Before fusion—a human history of fire

We humans are fire creatures. Tending fire is a species trait, a capacity we alone possess – and one we are not likely to tolerate willingly in any other species. But then we live on Earth, the only true fire planet, the ...

What is the surface of Neptune like?

As a gas giant (or ice giant), Neptune has no solid surface. In fact, the blue-green disc we have all seen in photographs over the years is actually a bit of an illusion. What we see is actually the tops of some very deep ...

Scientists harness nature's transport system to the brain

Scientists from Duke-NUS Medical School (Duke-NUS) have derived a structural model of a transporter at the blood-brain barrier called Mfsd2a (1). This is the first molecular model of this critical transporter, and could prove ...

Our sun may have eaten a super-Earth for breakfast

Our solar system sure seems like an orderly place. The orbits of the planets are predictable enough that we can send spacecraft on multi-year journeys to them and they will reliably reach their destinations. But we've only ...

Atoms placed precisely in silicon can act as quantum simulator

In a proof-of-principle experiment, researchers at UNSW Australia have demonstrated that a small group of individual atoms placed very precisely in silicon can act as a quantum simulator, mimicking nature - in this case, ...
