Physicists ‘teleport’ logic operation between separated ions

Physicists at the National Institute of Standards and Technology (NIST) have teleported a computer circuit instruction known as a quantum logic operation between two separated ions (electrically charged atoms), showcasing how quantum computer programs could carry out tasks in future large-scale quantum networks.

Quantum teleportation transfers data from one quantum system (such as an ion) to another (such as a second ion), even if the two are completely isolated from each other, like two books in the basements of separate buildings. In this real-life form of teleportation, only quantum information, not matter, is transported, as opposed to the Star Trek version of “beaming” entire human beings from, say, a spaceship to a planet.

Teleportation of quantum data has been demonstrated previously with ions and a variety of other quantum systems. But the new work is the first to teleport a complete quantum logic operation using ions, a leading candidate for the architecture of future quantum computers. The experiments are described in the May 31 issue of Science.

250-Million-Year-Old Bacteria Revived in Lab / Spores were found deep in rock salt formation

Scientists drilling into a New Mexico rock formation deep underground have brought to life four unknown strains of bacteria that have lain entombed in salt crystals for 250 million years.

The bacteria, like many of their kind, form into long-lasting protective spores. The scientists were able to revive the spores until the microbes reproduced.

The report, by a team of biologists and geologists, has already fueled speculation that spores of living organisms might somehow be transported from planet to planet, across the galaxy and over eons. It is a concept known as “panspermia,” which some see as a possible source for life arising on Earth.

Are mushrooms from outer space?

By Scott Mechura EBS Food Columnist

It isn’t a fruit or vegetable, it isn’t a fiber, and it certainly isn’t a protein. Then what is a mushroom?

Other than the mouthwatering anticipation with which chefs and foragers harvest morels or golden chanterelles from the Gallatin Valley each year, or prized truffles from France or Italy, most of us don’t often give the mushroom the same attention as local beef, trout, or fresh produce.

NASA Is Sending a Life-Hunting Drone to Saturn’s Huge Moon Titan

NASA is going to Titan.

The space agency announced today (June 27) that the next mission in its New Frontiers line of medium-cost missions will be Dragonfly, a rotorcraft designed to ply the skies of the huge, hazy and potentially life-hosting Saturn moon.

If all goes according to plan, Dragonfly will launch in 2026 and land on Titan eight years later, NASA officials said. The probe will then spend at least 2.5 years cruising around the 3,200-mile-wide (5,150 kilometers) moon, making two dozen flights that cover a total of about 110 miles (180 km).

What Could Possibly Be Cooler Than RoboBee? RoboBee X-Wing

They used to call it RoboBee—a flying machine half the size of a paperclip that could flap its pair of wings 120 times a second. It was always tethered to a power source, limiting its freedom. Now, though, RoboBee becomes RoboBee X-Wing, as Harvard researchers have added solar cells and an extra pair of wings, freeing the robot to blast off to a galaxy far, far away. Or at least partway across the room, as it can sustain flight for only half a second, and only indoors.

But hey, baby steps. The teeniest of quadrotors measure a few inches across and weigh a third of an ounce. RoboBee X-Wing is about the same size as those untethered fliers, but weighs a hundredth of an ounce, which earns it the distinction of being the lightest aerial vehicle to manage sustained untethered flight. One day that could make it ideal for navigating tight, sensitive spaces in a galaxy very, very near.

It took centuries, but we now know the size of the Universe

We can never see these more distant regions. Still, the observable Universe alone should be big enough for most people. Indeed, for scientists like Casey and Sheth, it remains a constant source of fascination.

We’re not even at the centre of our Solar System or at the centre of our galaxy

“Everything that we’ve learned about the Universe – how big it is, all the amazing objects that are in it – we do that simply by collecting these photons of light that have travelled millions and millions of light years only to come and die on our detectors, our cameras or radio telescopes,” says Sheth.
