Scientists Found Never-Before-Seen Crystals in Dust From The Chelyabinsk Meteorite

Posted by in categories: asteroid/comet impacts, existential risks

Researchers have discovered never-before-seen types of crystal hidden in tiny grains of perfectly preserved meteorite dust. The dust was left behind by a massive space rock that exploded over Chelyabinsk, Russia, nine years ago.

On 15 Feb 2013, an asteroid measuring 59 feet (18 meters) across and weighing 12,125 tons (11,000 metric tons) entered Earth’s atmosphere at around 41,600 mph (66,950 km/h).

D-Wave’s 500-Qubit Machine Hits the Cloud

Posted by in categories: computing, quantum physics

The standard approach toward building quantum computers, called the gate model, involves arranging qubits in circuits and making them interact with each other in a fixed sequence. In contrast, Burnaby, Canada-based D-Wave has long focused on what are called annealing quantum computers.

Powerful Sand Batteries Are Literally Dirt Simple

Posted by in category: energy

A startup from Finland called Polar Night Energy has developed an energy storage system based on sand. The idea is to store excess energy generated from clean electricity sources such as Wind, Solar, etc., to be reused days or even months later.

If it works, it will help solve the primary pain point of intermittent clean energy sources by making their final energy output more predictable and, therefore, more reliable.

Solar-plus-storage microgrid replaces diesel in remote Alaskan village

Posted by in category: energy

Blue Planet Energy has successfully deployed this first-of-its-kind project to support the residents of Shungnak, a remote community above the Arctic Circle in Alaska. The microgrid was designed to address the numerous challenges of operating in extreme conditions and break the community’s dependence on its expensive and polluting diesel generator power plant.

The resilient microgrid consists of a 225 kW solar array that can offset much of Shungnak’s energy needs. The system is integrated with 12 cabinets of 32 kWh Blue Ion LX battery systems, each storing excess energy for later use. In addition to reducing the village’s carbon footprint, the system also greatly decreases the high fuel and maintenance costs associated with running diesel generators in remote Alaska.

How to watch NASA reveal the first stunning James Webb telescope images

Posted by in category: space

The cosmic images will be unprecedented.


A giant golden eye flying around the sun about a million miles from Earth will give humans an unprecedented view of the universe.

The James Webb Space Telescope, a powerful $10 billion observatory run by NASA, the European Space Agency, and the Canadian Space Agency, has chilled down to its optimal temperature. Engineers have finished calibrating its scientific instruments. Now the telescope with a 21-foot-diameter mirror is open for business.

Researchers completely re-engineer yeast to make more biofuel

Posted by in categories: chemistry, sustainability

Circa 2020


A little while ago, we covered the idea of using photovoltaic materials to drive enzymatic reactions in order to produce specific chemicals. The concept is being considered mostly because doing the same reaction in a cell is often horribly inefficient, because everything else in the cell is trying to regulate the enzymes, trying to use the products, trying to convert the byproducts into something toxic, or up to something even more annoying. But in many cases, these reactions rely on chemicals that are only made by cells, leaving some researchers to suspect it still might be easier to use living things in the end.

Peter Tse — What Makes Brains Conscious?

Posted by in categories: chemistry, mathematics, neuroscience, physics

Everything we know, think and feel—everything!—comes from our brains. But consciousness, our private sense of inner awareness, remains a mystery. Brain activities—spiking of neuronal impulses, sloshing of neurochemicals—are not at all the same thing as sights, sounds, smells, emotions. How on earth can our inner experiences be explained in physical terms?
