Health check: is moderate drinking good for me?

For the past three decades or so, the conventional wisdom has been that drinking alcohol at moderate levels is good for us. The evidence for this has come from many studies that have suggested the death rate for moderate drinkers is lower than that for non-drinkers. In other words, we thought moderate drinkers lived longer than those who didn’t drink at all.

Our space weather mission will venture deeper into space than any other – here’s what it could achieve

Our space weather mission will venture deeper into space than any other – here’s what it could achieve

You may have noticed that some weather forecasts have started mentioning the chances of seeing an aurora, also known as northern lights. Just as the atmosphere of the Earth gives us terrestrial weather, the nearby, vast atmosphere of the sun gives rise to space weather – triggering events such as auroras. Many weather institutes around the world now provide forecasts of the weather in space because of the hazard it poses to services we rely on, such as satellite positioning services, power distribution and communications.

Gamma Ray Telescopes could Detect Starships Powered by Black Hole

In the course of looking for possible signs of Extra-Terrestrial Intelligence (ETI), scientists have had to do some really outside-of-the-box thinking. Since it is a foregone conclusion that many ETIs would be older and more technologically advanced than humanity, those engaged in the Search for Extra-Terrestrial Intelligence (SETI) have to consider what a more advanced species would be doing.

SpaceX Dragon 2 pulled off nail-biting landing – here’s the rocket science

A fiery Dragon lit up the sky over the Atlantic before cooling off with a watery splashdown on March 8. The SpaceX Dragon 2 capsule is of enormous significance for spaceflight as it has just become the first commercial vehicle to automatically dock with the International Space Station (ISS) and return to Earth. The spacecraft will now aim to carry astronauts to the ISS in a few months.

Moon mining could help meet future energy needs

If you were transported to the Moon this very instant, you would surely and rapidly die. That’s because there’s no atmosphere, the surface temperature varies from a roasting 130 degrees Celsius (266 F) to a bone-chilling minus 170 C (minus 274 F). If the lack of air or horrific heat or cold don’t kill you then micrometeorite bombardment or solar radiation will. By all accounts, the Moon is not a hospitable place to be.

Can robots ever have a true sense of self? Scientists are making progress

Having a sense of self lies at the heart of what it means to be human. Without it, we couldn’t navigate, interact, empathise or ultimately survive in an ever-changing, complex world of others. We need a sense of self when we are taking action, but also when we are anticipating the consequences of potential actions, by ourselves or others.

Hayabusa2 Left a Dark Spot Where it Touched Down on Ryugu. Engineers Aren’t Sure Why

On June 27th, 2018, the Japanese Aerospace Exploration Agency‘s (JAXA) Hayabusa2 spacecraft rendezvoused with the asteroid 162173 Ryugu. Carrying on in the same tradition as its predecessor, Hayabusa2 recently conducted landing operations on the asteroid’s surface as part of the agency’s second sample-return mission from an asteroid.
