Coronavirus Florida: Bradenton ‘church’ ordered to stop selling bleach as COVID-19 miracle cure

Posted by in categories: biotech/medical, neuroscience

Fyodor Rouge, this is the church I was telling you about.


The Bradenton-based organization falsely claims that the treatment is effective for a number of conditions, including Alzheimer’s disease, brain disease, cancer, HIV and AIDS, according to the Food and Drug Administration.

Iran launches its first military satellite

Posted by in categories: biotech/medical, military

As the world grapples with the coronavirus pandemic and historically low oil prices, the missile launch may signal a new willingness to take risks by Iran.


It said the satellite — dubbed the Nour — was deployed from the Qassed two-stage launcher from the Markazi desert, a vast expanse in Iran’s central plateau.

The satellite “orbited the Earth at 425km [264 miles]”, said the website. “This action will be a great success and a new development in the field of space for Islamic Iran.”

Study reveals single-step strategy for recycling used nuclear fuel

Posted by in categories: chemistry, engineering, nuclear energy, sustainability

A typical nuclear reactor uses only a small fraction of its fuel rod to produce power before the energy-generating reaction naturally terminates. What is left behind is an assortment of radioactive elements, including unused fuel, that are disposed of as nuclear waste in the United States. Although certain elements recycled from waste can be used for powering newer generations of nuclear reactors, extracting leftover fuel in a way that prevents possible misuse is an ongoing challenge.

Now, Texas A&M University engineering researchers have devised a simple, proliferation-resistant approach for separating out different components of . The one-step chemical reaction, described in the February issue of the journal Industrial & Engineering Chemistry Research, results in the formation of crystals containing all of the leftover nuclear elements distributed uniformly.

The researchers also noted that the simplicity of their recycling approach makes the translation from lab bench to industry feasible.

Flyt Aerospace bids its Red Hummingbird hoverbike for US Air Force’s Agility Prime

Posted by in category: military

Flyt Aerospace is offering its Red Hummingbird pilot-optional, fully-electric hoverbike for the US Air Force’s (USAF’s) Agility Prime electric vertical takeoff and landing (eVTOL) procurement effort.

The eight-motor, multi-rotor Red Hummingbird is designed for speeds of 0–97 km/h in 5.1 seconds, payload capacity of up to 113 kg, a cost of USD2.40 worth of electricity per flight, and the ability to operate for 20–30 minutes per charge. The aircraft is also designed to create only 65 db of noise at 50 ft altitude. Flyt is offering the Red Hummingbird for the Agility Prime 1–2 person capacity area of interest (AOI) 2, according to company founder and CEO Ansel Misfeldt.

Misfeldt told Jane’s on 1 May that the Red Hummingbird has a fully-built prototype currently in flight testing, but that the aircraft has yet to fly with a human. Flyt has so far been flying the aircraft with weights in the pilot seat to ensure system checkout before flying with a pilot.

How a Retrovirus or RNA Virus Works

Posted by in category: biotech/medical

COVID-19’s genes are encoded in RNA instead of DNA. COVID-19 uses reverse transcriptase to transform its single-stranded RNA into double-stranded DNA. It is DNA that stores the genome of human cells and cells from other higher life forms. Once transformed from RNA to DNA, the new COVID-19 DNA can be integrated into the genome of the infected cells. When the DNA versions of the retroviral genes have been incorporated into the genome, the cell then is tricked into copying those genes as part of its normal replication process and making millions of COVID-19 cells… In other words, the cell does the work of the virus for it.

That’s why it was necessary to upgrade Stem Cell Neurotherapy for COVID-19 by adding T-Cells, B-Cells, and Natural Killer Cells to the arsenal. It was not enough to just regenerate new lung cells to replace the lung cells infected by COVID-19, but the COVID-19 Virus Cells had to be attacked and destroyed, and its RNA single strand had to be unraveled, in order to prevent them from invading and infecting the newly regenerated lung cells.


A retrovirus is a virus whose genes are encoded in RNA, and, using an enzyme called reverse transcriptase, replicates itself by first reverse-coding its genes into the DNA of the cells it infects. Like other viruses, retroviruses need to use the cellular machinery of the organisms they infect to make copies of themselves. However, infection by a retrovirus requires an additional step. The retrovirus genome needs to be reverse-transcribed into DNA before it can be copied in the usual way. The enzyme that does this backward transcription is known as reverse transcriptase.

Pathogen Mishaps Rise as Regulators Stay Clear

Posted by in categories: biotech/medical, government

We are being told that mistakes can not happen in labs. I for one do not believe such, so let me take you on a trip down memory lane to 2014, around the same year funding of gain of function was stopped.

Lab workers at different sites accidentally jabbed themselves with needles contaminated by anthrax or West Nile virus. An air-cleaning system meant to filter dangerous microbes out of a lab failed, but no one knew because the alarms had been turned off. A batch of West Nile virus, improperly packed in dry ice, burst open at a Federal Express shipping center. Mice infected with bubonic plague or Q fever went missing. And workers exposed to Q fever, brucellosis or tuberculosis did not realize it until they either became ill or blood tests detected the exposure.


The recent number of mistakes documented at federal laboratories involving anthrax, flu and smallpox viruses have contributed to a debate over lax government oversight at high-level containment labs.
