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.

Source: Lund University.

Researchers at Lund University in Sweden have developed an algorithm that combines data from a simple blood test and brief memory tests, to predict with great accuracy who will develop Alzheimer’s disease in the future.

The Orca: This Autonomous Submarine Will Fight the Wars of the Future

Posted by in categories: military, robotics/AI

The 50-ton Voyager was developed by Boeing’s PhantomWorks division, which is devoted to advanced new technologies, succeeding a series of smaller Echo Seeker and Echo Ranger UUVs. The 15.5-meter long Echo Voyager has a range of nearly 7500 miles. It has also deployed at sea up to three months in a test, and theoretically could last as long as six months.

Supposedly, Voyager also can dive as deep as 3350 meters—while few military submarines are (officially) certified for dives below 500 meters.


And it isn’t the only robot submarine in the works.
