New Policies Needed to Advance Space Mining

Posted by in categories: economics, space

Space has long captured the human imagination—as a source of wonder, a place of discovery, a realm for aspirations. But increasingly, space is viewed as a frontier of economic opportunity as scientists, technologists, and entrepreneurs invest their ingenuity and wealth to bring the vastness of space within human grasp.

This economic development hinges on an ability to utilize what we term “space resources.” The resources in just the inner solar system are nearly infinite compared with those on Earth. For example, one large metallic asteroid such as 16 Psyche is thought to contain enough metals to last humans for millions of years at current consumption rates. And society has barely scratched the surface in harnessing the energy of the sun. Accessing space resources is increasingly important as the world confronts the finite nature of resources and the increasing environmental and social costs to develop them.

This Massive, Nightmare Bee Was Once Thought Extinct. Not Anymore

Posted by in category: futurism

You’d think that the world’s biggest bee would be hard to lose track of. But Wallace’s Giant Bee — an Indonesian species with a 2.5-inch (6.4 centimeters) wingspan and enormous mandibles — was last seen by researchers in 1981; it was feared to be extinct. However, scientists finally spotted the rare bee in January, in the Indonesian province of North Maluku on the Maluku Islands. They detected a solitary female bee after investigating the region for five days, and a photographer captured the first-ever images of a living Wallace’s Giant Bee (Megachile pluto) at the insect’s nest in an active termite mound.


Wallace’s Giant Bee — the largest bee on Earth — hasn’t been seen for decades. However, scientists recently tracked it down on an island in Indonesia.

Here’s the Only Picture Ever Taken of Concorde Flying at Mach 2 (1,350 Mph) in April 1985

Posted by in categories: climatology, military

The only picture ever taken of Concorde flying at Mach 2 (1,350 mph). Taken by Adrian Meredith from an RAF Tornado fighter jet, which only rendezvoused with Concorde for 4 minutes over the Irish Sea: The Tornado was rapidly running out of fuel, struggling to keep up with Concorde at Mach 2.

“Extreme Relic”–Merging Black Holes Illuminated

Posted by in categories: cosmology, materials

In the nearby Whirlpool galaxy and its companion galaxy, M51b, two supermassive black holes heat up and devour surrounding material. These two monsters should be the most luminous X-ray sources in sight, but a new study using observations from NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array) mission shows that a much smaller object is competing with the two behemoths.

The most stunning features of the Whirlpool galaxy – officially known as M51a – are the two long, star-filled “arms” curling around the galactic center like ribbons. The much smaller M51b clings like a barnacle to the edge of the Whirlpool. Collectively known as M51, the two galaxies are merging.

At the center of each galaxy is a supermassive black hole millions of times more massive than the Sun. The galactic merger should push huge amounts of gas and dust into those black holes and into orbit around them. In turn, the intense gravity of the black holes should cause that orbiting material to heat up and radiate, forming bright disks around each that can outshine all the stars in their galaxies.

Physicists get thousands of semiconductor nuclei to do ‘quantum dances’ in unison

Posted by in categories: computing, particle physics, quantum physics

A team of Cambridge researchers have found a way to control the sea of nuclei in semiconductor quantum dots so they can operate as a quantum memory device.

Quantum dots are crystals made up of thousands of atoms, and each of these atoms interacts magnetically with the trapped electron. If left alone to its own devices, this interaction of the electron with the nuclear spins, limits the usefulness of the electron as a bit—a qubit.

Led by Professor Mete Atatüre, a Fellow at St John’s College, University of Cambridge, the research group, located at the Cavendish Laboratory, exploit the laws of quantum physics and optics to investigate computing, sensing or communication applications.

Physicists Have Finally Solved a Fundamental Mystery Concerning The Insides of Atoms

Posted by in categories: electronics, particle physics

Something about atoms has never added up. Fundamental particles called quarks get kind of sluggish once they’re caught up in crowds of protons and neutrons – and quite frankly, they shouldn’t.

For decades, physicists have hunted for clues on the quark’s tendency to slow down in larger atoms, but have come up empty-handed. But now, a closer look at old data has finally revealed a clue to explain this strange phenomenon.

A massive team of physicists known as the CLAS Collaboration (after the CEBAF Large Acceptance Spectrometer) recently ran through data gathered from previous experiments at the Jefferson Lab’s Continuous Electron Beam Accelerator Facility.

Goodyear’s “living” car tyre converts carbon dioxide into oxygen

Posted by in categories: 3D printing, health, transportation

This 3D-printed concept wheel by tyre manufacturer Goodyear uses living moss to absorb moisture from the road, before converting it into oxygen through photosynthesis.

The Oxygene tyre was revealed at this year’s Geneva Motor Show that officially kicked off yesterday, 8 March 2018.

The concept is a response to research conducted by the World Health Organisation (WHO) that revealed more than 80 per cent of people who live in urban areas are exposed to air quality levels deemed to be unsafe.
