Alberta excrement being tested for COVID-19 as researchers refine sewage surveillance

Posted by in categories: biotech/medical, health

“The logistics of clinical testing don’t let you sample everybody, but sewage does sample everybody.”-Steve Hrudey.

Raw sewage being flushed into Alberta’s municipal wastewater plants could help public health officials better track — and predict — the spread of COVID-19.

A team of Alberta scientists has joined a growing international effort to sample wastewater for traces of SARS-CoV-2, the virus responsible for the disease.

How Graphene Could Help Us Build Bigger and Better Quantum Computers

Posted by in categories: quantum physics, supercomputing

Quantum computers can solve problems in seconds that would take “ordinary” computers millennia, but their sensitivity to interference is majorly holding them back. Now, researchers claim they’ve created a component that drastically cuts down on error-inducing noise.

Quantum computers use quantum bits, or qubits, which can represent a one, a zero, or any combination of the two simultaneously. This is thanks to the quantum phenomenon known as superposition.

Slower Biological Aging In People On A Calorie Restricted Diet

Posted by in categories: biological, food, life extension

Here’s my latest video!

Calorie restriction (CR) is well known to extend average and maximal lifespan in a variety of animal models, but what about in people? In this video, I present evidence showing that CR slows biological aging, which suggests that CR will positively affect lifespan in people.

Incredible Test Flight Footage Shows Flying Sports Car Taking To The Skies

Posted by in categories: futurism, transportation

Articel from Unilad. The article contains a You Tube video as well on the car’s flight. It looks fantastic to me. To think that flight technology can be made this compact.

It’s not really like the flying car’s we see in sci-fi films, but this may be the first step. Besides, I’m not sure flying cars were practical anyway.

Blockchain aims to solve AI ethics and bias issues

Flying Car Gets Approved for Road Use, Aviation Certification Still Years Away

Posted by in categories: law, transportation

We must admit, despite all the great promises made by companies over the years, we never thought we’ll get to the point where we’ll actually see flying cars become road legal. Yet this is exactly what Dutch company Pal-V announced this week.

Guppy Evolution Fast Forwards

Posted by in categories: biological, evolution, genetics, singularity

The great powerful guppy can essentially evolve 10 million times faster than usual. Which could lead to humans evolving faster too leading to a biological singularity.

Although natural selection is often viewed as a slow pruning process, a dramatic new field study suggests it can sometimes shape a population as fast as a chain saw can rip through a sapling. Scientists have found that guppies moved to a predator-free environment adapted to it in a mere 4 years—a rate of change some 10,000 to 10 million times faster than the average rates gleaned from the fossil record. Some experts argue that the 11-year study, described in today’s issue of Science,* may even shed light on evolutionary patterns that occur over eons.

A team led by evolutionary biologist David Reznick of the University of California, Riverside, scooped guppies from a waterfall pool brimming with predators in Trinidad’s Aripo River, then released them in a tributary where only one enemy species lurked. In as little as 4 years, male guppies in the predator-free tributary were already detectably larger and older at maturity when compared with the control population; 7 years later females were too. Guppies in the safer waters also lived longer and had fewer and bigger offspring.

4.5-bil­lion-year-old Ice on Comet ‘Fluffi­er Than Cap­puc­ci­no Froth’

Posted by in category: space

After years of detective work, scientists working on the European Space Agency (ESA) Rosetta mission have now been able to locate where the Philae lander made its second and penultimate contact with the surface of Comet 67P/Churyumov-Gerasimenko on 12 November 2014, before finally coming to a halt 30 metres away. This landing was monitored from the German Aerospace Center Philae Control Center. Philae left traces behind; the lander pressed its top side and the housing of its sample drill into an icy crevice in a black rocky area covered with carbonaceous dust. As a result, Philae scratched open the surface, exposing ice from when the comet was formed that had been protected from the Sun’s radiation ever since. The bare, bright icy surface, the outline of which is somewhat reminiscent of a skull, has now revealed the contact point, researchers write in the scientific publication Nature.

All that was known previously was the location of the first contact, that there had been another impact following the rebound, and the location of the final landing site where Philae came to rest after two hours and where it was found towards the end of the Rosetta mission in 2016. “Now we finally know the exact place where Philae touched down on the comet for the second time. This will allow us to fully reconstruct the lander’s trajectory and derive important scientific results from the telemetry data as well as measurements from some of the instruments operating during the landing process,” explains Jean-Baptiste Vincent from the DLR Institute of Planetary Research, who was involved in the research published today. “Philae had left us with one final mystery waiting to be solved,” says ESA’s Laurence O’Rourke, the lead author of the study.

Gravitons Create ‘Noise’ in Gravitational Wave Detectors, New Study Reveals

Posted by in category: physics

This could lead to artificial gravity like we see on star trek.

Many physicists said that gravitons exist but some believe that it is impossible to observe it in the natural world. Recent studies suggest that gravitons create ‘noise’ making them easier to spot.
