Majority of people return lost wallets – here’s the psychology and which countries are the most honest

Honesty is one of the traits we value most in others. We often assume it is a rather rare quality, making it important for us to find out who we can actually trust in this selfish world. But according to new research, there’s no need to be so cynical – it turns out most people in the world are honourable enough to return a lost wallet, especially if it contains a lot of cash.

Two Earth-Like Worlds Found Orbiting a Red Dwarf Only 12.5 Light-Years Away!

Two Earth-Like Worlds Found Orbiting a Red Dwarf Only 12.5 Light-Years Away!

In the past few decades, there has been an explosion in the number of planets discovered beyond our Solar System. With over 4,000 confirmed exoplanets to date, the process has gradually shifted from discovery towards characterization. This consists of using refined techniques to determine just how likely a planet is to be habitable.

Explainer: What Is an Atomic Clock?

Explainer: What Is an Atomic Clock?

The clock is ticking: A technology demonstration that could transform the way humans explore space is nearing its target launch date of June 24, 2019. Developed by NASA's Jet Propulsion Laboratory in Pasadena, California, the Deep Space Atomic Clock is a serious upgrade to the satellite-based atomic clocks that, for example, enable the GPS on your phone.

Black plastic can’t be recycled – but we’ve just found a way to use the carbon in renewable energy

Black plastic can’t be recycled – but we’ve just found a way to use the carbon in renewable energy

The big problem with plastics is that though they last for a very long time, most are thrown away after only one use. Since plastics were invented in the 1950s, about 8,300 million metric tonnes (Mt) have been made, but over half (4,900 Mt) is already in landfill or has been lost to the environment. In 2010 alone, an estimated 4.8 to 12.7 Mt went into the oceans.

Can entangled quantum bits be used to probe black holes?

Can entangled quantum bits be used to probe black holes?

Physicists have used a seven-qubit quantum computer to simulate the scrambling of information inside a black hole, heralding a future in which entangled quantum bits might be used to probe the mysterious interiors of these bizarre object

Earth has a Water Cycle. Mars has a Dust Cycle

Earth has a Water Cycle. Mars has a Dust Cycle

To say there are some myths circulating about Martian dust storms would be an understatement. Mars is known for its globe-encircling dust storms, the likes of which are seen nowhere else. Science fiction writers and Hollywood movies often make the dust storms out to be more dangerous than they really are. In “The Martian,” a powerful dust storm destroys equipment, strands Matt Damon on Mars, and forces him into a brutal struggle for survival.

Ethics of AI: how should we treat rational, sentient robots – if they existed?

Ethics of AI: how should we treat rational, sentient robots – if they existed?

Imagine a world where humans co-existed with beings who, like us, had minds, thoughts, feelings, self-conscious awareness and the capacity to perform purposeful actions – but, unlike us, these beings had artificial mechanical bodies that could be switched on and off.

How NASA's Spitzer Has Stayed Alive for So Long

How NASA's Spitzer Has Stayed Alive for So Long

After nearly 16 years of exploring the cosmos in infrared light, NASA's Spitzer Space Telescope will be switched off permanently on Jan. 30, 2020. By then, the spacecraft will have operated for more than 11 years beyond its prime mission, thanks to the Spitzer engineering team's ability to address unique challenges as the telescope slips farther and farther from Earth.

Inflatable Heat Shield Could Deliver Heavy Payloads to Worlds With a Thick Atmosphere

Inflatable Heat Shield Could Deliver Heavy Payloads to Worlds With a Thick Atmosphere

One of the greater challenges of sending payloads to Mars is having to contend with the planet’s atmosphere. While incredibly thin compared to Earth’s (with roughly half of 1% of Earth’s air pressure), the resulting air friction is still an issue for spacecraft looking to land there. And looking to the future, NASA hopes to be able to land heavier payloads on Mars as well as other planets – some of which may have atmospheres as dense as Earth.
