What’s the Deal with 3D Printed Food?

Posted by in categories: 3D printing, food

3D printed food is no longer the domain of sci-fi fantasy. It’s here and it’s real: but is it really a big deal, or is it just a passing fad?


In science fiction television shows and movies such as those in the Star Trek universe, the food synthesizers or replicators were electronic devices that took base elements and transformed them into any type of food that was desired. This seemingly miraculous device could only exist in the world of science fiction — at least for now. However, thanks to the advances in 3D printing, it is now possible to create food that mimics the taste, shape, and color of familiar dishes.

Over the past few years, 3D printers have become more commonplace in commercial industries and are used to create all types of items that range from small models and jewelry up to large construction items used to create buildings. But what about 3D printed foods? Is it the future of gastronomy, or just a quirky fad?

Light meets superconducting circuits

Posted by in categories: computing, quantum physics

In the last few years, several technology companies including Google, Microsoft, and IBM, have massively invested in quantum computing systems based on microwave superconducting circuit platforms in an effort to scale them up from small research-oriented systems to commercialized computing platforms. But fulfilling the potential of quantum computers requires a significant increase in the number of qubits, the building blocks of quantum computers, which can store and manipulate quantum information.

But quantum signals can be contaminated by thermal noise generated by the movement of electrons. To prevent this, superconducting quantum systems must operate at ultra-low temperatures—less than 20 milli-Kelvin—which can be achieved with cryogenic helium-dilution refrigerators.

The output microwave signals from such systems are amplified by low-noise high-electron mobility transistors (HEMTs) at low temperatures. Signals are then routed outside the refrigerator by microwave , which are the easiest solutions to control and read but are poor heat isolators, and take up a lot of space; this becomes a problem when we need to scale up qubits in the thousands.

Methane-eating microbes make their own oxygen

Posted by in categories: biological, food, space

Circa 2010


Researchers have discovered a possible new species of bacteria that survives by producing and ‘breathing’ its own oxygen. The finding suggests that some microbes could have thrived without oxygen-producing plants on the early Earth — and on other planets — by using their own oxygen to garner energy from methane (CH4).

“The mechanism we have now discovered shows that, long ago, these organisms could have exploited the methane sources on Earth and possibly on other planets and moons by mechanisms that we didn’t know existed,” says Mike Jetten, a microbiologist at Radboud University Nijmegen in the Netherlands and part of the team that conducted the study, which is published in Nature today1.

Scientists find ultraviolet light may create life-essential chemicals

Posted by in categories: chemistry, mapping, particle physics, space

Circa 2016 o.o!


The theory used to be that hydrocarbons were created in “shocks,” or violent stellar events that cause a lot of turbulence and, with the shock waves, make atoms into ions, which are more likely to combine.

The data from the European Space Agency’s Herschel Space Observatory has since proved that theory wrong. Scientists at Herschel studied the components in the Orion Nebula, mapping the amount, temperature and motions for the carbon-hydrogen molecule (CH), the carbon-hydrogen positive ion (CH+) and their parent molecule: the carbon ion (C+).

The efficacy and safety of Favipiravir in treatment of COVID-19: a systematic review and meta-analysis of clinical trials

Posted by in categories: biotech/medical, health

The novel coronavirus outbreak began in late December 2019 and rapidly spread worldwide, critically impacting public health systems. A number of already approved and marketed drugs are being tested for repurposing, including Favipiravir. We aim to investigate the efficacy and safety of Favipiravir in treatment of COVID-19 patients through a systematic review and meta-analysis. This systematic review and meta-analysis were reported in accordance with the PRISMA statement. We registered the protocol in the PROSPERO (CRD42020180032). All clinical trials which addressed the safety and efficacy of Favipiravir in comparison to other control groups for treatment of patients with confirmed infection with SARS-CoV2 were included. We searched electronic databases including LitCovid/PubMed, Scopus, Web of Sciences, Cochrane, and Scientific Information Database up to 31 December 2020.

Simple Diagnostic Tool Predicts Individual Risk of Alzheimer’s

Posted by in categories: biotech/medical, information science, neuroscience

Summary: A new algorithm that uses data from memory tests and blood samples is able to accurately predict an individual’s risk for developing Alzheimer’s disease.
