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.
Get ready for stunning astronomical photos and data, scientists say.
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.
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?

Get Started with Squarespace today: http://squarespace.com/isaacarthur. To journey across the stars requires voyages of centuries or more, ensuring the crew will be long dead by the time they arrive. If you want your crew available to colonize new worlds after their interstellar voyage, you either have to extend their lives, train their descendants, or freeze them till they arrive. We will examine the third option day, freezing people with cryonics, using hibernation, or suspended animation, or some other form of stasis the future might offer.
A Matrioshka Brain is a supermassive structure in space consisting of processors and connected to each other into a massive computer around a sun harnessing its energy completely. So far we haven’t built one as we don’t have the technology for it but when we do the question will be if people will be lost in the vast computing power of the Matrishka brain.

The search for a way to treat Alzheimer’s disease has puzzled scientists for decades. This may be why some researchers are shifting their focus slightly, investigating whether treating the systems affected by Alzheimer’s (as opposed to the causes) may better help them find a treatment.
This is exactly what researchers of a new study have shown – finding that drugs normally used to treat ADHD may actually show promise in managing symptoms of Alzheimer’s disease.
The researchers conducted a systematic review which looked at how noradrenergic drugs (commonly used for ADHD) work for managing Alzheimer’s disease symptoms. The review found that taking these drugs improved certain brain functions and other symptoms, such as apathy, in patients with Alzheimer’s disease.
The first batch of photos, which have taken weeks to process from raw telescope data, are expected to offer a compelling glimpse at what Webb will capture on the science missions that lie ahead.
NASA on Friday posted a list of the five celestial subjects chosen for its showcase debut of Webb, built for the U.S. space agency by aerospace giant Northrop Grumman Corp (NOC.N).
Among them are two nebulae — enormous clouds of gas and dust blasted into space by stellar explosions that form nurseries for new stars — and two sets of galaxy clusters.
