While today’s computers—referred to as classical computers—continue to become more and more powerful, there is a ceiling to their advancement due to the physical limits of the materials used to make them. Quantum computing allows physicists and researchers to exponentially increase computation power, harnessing potential parallel realities to do so.

Quantum computer chips are astoundingly small, about the size of a fingernail. Scientists have to not only build the computer itself but also the ultra-protected environment in which they operate. Total isolation is required to eliminate vibrations and other external influences on synchronized atoms; if the atoms become ‘decoherent’ the quantum computer cannot function.

A spider-like moon rover heading to the lunar surface in 2021 is designed to explore the underground lava tubes in which astronauts might one day live.

Scientists in Florida have developed process to create methane using aerobic digester.

The result was a bizarre, Lego-like human tissue that replicates the basic circuits behind how we decide to move. Without external prompting, when churned together like ice cream, the three ingredients physically linked up into a fully functional circuit. The 3D mini-brain, through the information highway formed by the artificial spinal cord, was able to make the lab-grown muscle twitch on demand.

In other words, if you think isolated mini-brains—known formally as brain organoids—floating in a jar is creepy, upgrade your nightmares. The next big thing in probing the brain is assembloids—free-floating brain circuits—that now combine brain tissue with an external output.

The end goal isn’t to freak people out. Rather, it’s to recapitulate our nervous system, from input to output, inside the controlled environment of a Petri dish. An autonomous, living brain-spinal cord-muscle entity is an invaluable model for figuring out how our own brains direct the intricate muscle movements that allow us stay upright, walk, or type on a keyboard.

The device, which is like a smartphone in the eye, took home an award at the year’s biggest tech conference, but it’s not quite ready for prime time.

The automaker is doggedly sticking with the clean fuel that has taken a backseat to batteries. The hydrogen-generation station at the Long Beach port, the first that’s megawatt-scale and 100% renewable, will fuel arriving Toyota Mirai sedans and its Project Portal semi.

InSight lander’s “mole” was unable to hammer through the Martian soil, and unusually dusty solar panels meant the robot was generating less power.

This last year has been not been one for the social calendar. It has left us all feeling more and more isolated with lockdown after lockdown and restricted travel options globally. It is something we need to actively work to overcome, for our own sakes and for those around us, it is as detrimental to our long term health as smoking, obesity or having an alcohol disorder. It increases the risk of many health conditions, and even alters gene expressions. If you want to know even more detail I break it down in this new video, and look out for those who are having a rougher time, pay it forward. Make this world a place you want to live in…

In Loneliness As Deadly As Smoking-How It Impacts Your Health & Longevity I will be talking about how social isolation, something becoming more and more apparent in many countries and cities across the globe, is a serious threat to health and longevity.

Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, an international team of astronomers has performed observations of HSC J120505.09−000027.9—the most distant red quasar so far detected and found that it showcases an extended emission of ionized carbon. The finding is reported in a paper published January 4 on arXiv.org.

Quasars, or quasi–stellar objects (QSOs), are extremely luminous active galactic nuclei (AGN) containing supermassive central black holes with accretion disks. Their redshifts are measured from the strong spectral lines that dominate their visible and ultraviolet spectra. Some QSOs are dust-reddened, hence dubbed red quasars. These objects have a non-negligible amount of dust extinction, but are not completely obscured.

Astronomers are especially interested in studying high-redshift quasars (at redshift higher than 5.0) as they are the most luminous and most distant compact objects in the observable universe. Spectra of such QSOs can be used to estimate the mass of supermassive black holes that constrain the evolution and formation models of quasars. Therefore, high-redshift quasars could serve as a powerful tool to probe the early universe.
