HONG KONG—China is aggressively advancing alternative theories about the source of the coronavirus that causes Covid-19, muddying the waters as the World Health Organization prepares to launch a long-awaited investigation into the origins of the pandemic. In recent weeks, Chinese state media, often suggesting the virus came from outside China, have seized on a series of recent studies that show it was spreading outside the country earlier than first assumed. Government officials have also pushed the theory that the virus could have hitched a ride into the central Chinese city of Wuhan on frozen-food imports. After outbreaks in multiple Chinese cities in recent months including Beijing, Shanghai, Tianjin and elsewhere, authorities pointed to frozen-food packaging as the potential origin. https://www.wsj.com/articles/china-pushes-alternative-theori…1607445463

TORONTO (AP) — Officials in Canada’s most populous province have confirmed the first two known Canadian cases of a more contagious variant of COVID-19 that was first identified in the United Kingdom.

The province’s associate chief medical officer says that the cases are a couple from Durham Region, just east of Toronto, with no known travel history, exposure or high-risk contacts.

The new variant is believed to spread more easily and faster than the original version of the disease but is not believed to be more deadly.

NASA scientists and their colleagues are now proposing corporate financing for a human mission to Mars. This raises the prospect that a spaceship named the Microsoft Explorer or the Google Search Engine could one day go down in history as the first spaceship to bring humans to the Red Planet.

The proposal suggests that companies could drum up $160 billion for a human mission to Mars and a colony there, rather than having governments fund such a mission with tax dollars.

Joel Levine, a senior research scientist at NASA Langley Research Center, was quoted in a release in the Journal of Cosmology by Dr. Rhawn Joseph. The plan covers “every aspect of a journey to the Red Planet — the design of the spacecrafts, medical health and psychological issues, the establishment of a Mars base, colonization, and a revolutionary business proposal to overcome the major budgetary obstacles which have prevented the U.S. from sending astronauts to Mars,” said Levine.

UV light-emitting diodes (UV LEDs) are an emerging technology and a UV source for pathogen inactivation, however low UV-LED wavelengths are costly and have low fluence rate. Our results suggest that the sensitivity of human Coronavirus (HCoV-OC43 used as SARS-CoV-2 surrogate) was wavelength dependent with 267 nm ~ 279 nm 286 nm 297 nm. Other viruses showed similar results, suggesting UV LED with peak emission at ~286 nm could serve as an effective tool in the fight against human Coronaviruses.

A Stanford Medicine team used human stem cells to assemble a working nerve circuit connecting brain tissue to muscle tissue. The research could enable scientists to better understand neurological disorders that affect movement.

One of the most consumed drugs in the US – and the most commonly taken analgesic worldwide – could be doing a lot more than simply taking the edge off your headache, recent evidence suggests.

Acetaminophen, also known as paracetamol and sold widely under the brand names Tylenol and Panadol, also increases risk-taking, according to a September 2020 study that measured changes in people’s behaviour when under the influence of the common over-the-counter medication.

“Acetaminophen seems to make people feel less negative emotion when they consider risky activities – they just don’t feel as scared,” said neuroscientist Baldwin Way from The Ohio State University in September 2020.

Severe allergy-like reactions in at least eight people who received the COVID-19 vaccine produced by Pfizer and BioNTech (and Moderna now) over the past 2 weeks may be due to a compound in the packaging of the messenger RNA (mRNA) that forms the vaccine’s main ingredient, scientists say. A similar mRNA vaccine developed by Moderna, which was authorized for emergency use in the United States on Friday, also contains the compound, polyethylene glycol (PEG) PEG has never been used before in an approved vaccine, but it is found in many drugs that have occasionally triggered anaphylaxis—a potentially life-threatening reaction that can cause rashes, a plummeting blood pressure, shortness of breath, and a fast heartbeat. Some allergists and immunologists believe a small number of people previously exposed to PEG may have high levels of antibodies against PEG, putting them at risk of an anaphylactic reaction to the vaccine.

Life-threatening responses seen in at least eight people could be linked to polyethylene glycol, known to trigger reactions to some drugs.

Peterborough, ON — Ontario Power Generation (OPG), its subsidiary Laurentis Energy Partners (Laurentis), BWXT ITG Canada Inc. and its affiliates (BWXT) are making significant progress toward the production of molybdenum-99 (Mo-99) at OPG’s Darlington Nuclear Generating Station. Mo-99 is a much-needed medical isotope used in over 40 million procedures a year to detect cancers and diagnose various medical conditions.

Over the past 24 months, a team of more than 100 personnel at BWXT and Laurentis designed specialized tooling at BWXT’s facility in Peterborough to enable the production of Mo-99 at Darlington. The manufacturing of this specialized tooling is currently underway at the same BWXT facility in Peterborough.

BWXT has also built a fabrication facility at its current location in Peterborough to produce Mo-99 components that will be delivered by the specialized tooling, which will be installed at Darlington. The tooling will deliver the molybdenum into the Darlington reactor for irradiation, which will enable Darlington to become the first commercial operating nuclear reactor to produce Mo-99.

Poor sleep and other issues with circadian rhythm are common for people with Alzheimer’s disease. Now researchers may have a clue to why.

“If your circadian clock is not quite right for years and years—you routinely suffer from disrupted sleep at night and napping during the day—the cumulative effect of chronic dysregulation could influence inflammatory pathways such that you accumulate more amyloid plaques,” says Erik Musiek.

Fractured sleep, daytime sleepiness, and other signs of disturbance in one’s circadian rhythm are common complaints of people with Alzheimer’s disease, and the problems only get worse as the disease progresses.
