Less sugar…More muscle!

Researchers from Tokyo Metropolitan University have shown that skeletal muscle satellite cells, key players in muscle repair, proliferate better in low glucose environments. This is contrary to conventional wisdom that says mammalian cells fare better when there is more sugar to fuel their activities. Because ultra-low glucose environments do not allow other cell types to proliferate, the team could produce pure cultures of satellite cells, potentially a significant boost for biomedical research.

Healthy muscles are an important part of a healthy life. With the wear and tear of everyday use, our muscles continuously repair themselves to keep them in top condition. In recent years, scientists have begun to understand how muscle repair works at the cellular level. Skeletal muscle satellite cells have been found to be particularly important, a special type of stem cell that resides between the two layers of sheathing, the sarcolemma and basal lamina, that envelopes myofiber cells in individual muscle fibers. When myofiber cells get damaged, the satellite cells go into overdrive, multiplying and finally fusing with myofiber cells. This not only helps repair damage, but also maintains muscle mass. To understand how we lose muscles due to illness, inactivity, or age, getting to grips with the specific mechanisms involved is a key challenge for medical science.

First Arctic Navigation in February


Alexander Ryumin/TASS

A tanker sailed through Arctic sea ice in February for the first time, the latest sign of how quickly the pace of climate change is accelerating in the Earth’s northernmost regions.

The Christophe de Margerie was accompanied by the nuclear-powered 50 Let Pobedy icebreaker as it sailed back to Russia this month after carrying liquified natural gas to China through the Northern Sea Route in January. Both trips broke navigation records…

The experimental voyage happened after a year of extraordinarily warm conditions in the Arctic that have sent shockwaves across the world, from the snowstorm that blanketed Spain in January to the blast of cold air that swept through Canada in mid-February, moving deep into the South as far as Texas.

Facebook blocked news pages as a negotiating tactic in Australia

Facebook may wait up to a week before unblocking some of the pages of hundreds of non-media organisations caught up in its news ban, while anti-vaccination content and misinformation continues to run rampant on the social media platform.

Content designated as news was blocked on Facebook in Australia on Thursday morning in response to the federal government’s news media code, which would require the tech giant to negotiate with news publishers for payment for content…

Tim Hanslow, head of social at Preface Social Media and who also helps run the Australian Community Managers group on Facebook, told Guardian Australia he had heard from a couple of community managers who had been contacted by their Facebook representatives and were told an appeals process would be put in place for people to plead their case…

“An appeals process for the ban will launch on Feb 25 and you can request your page be assessed as outside the news ban. All of the government pages/sites caught up in this should be reinstated.”

So, just wait around for a spell and Facebook will decide who is banned, who isn’t…and apparently what is news.

The new Boom Towns are ZOOM TOWNS

First, there were boomtowns. Now, there are Zoom towns.

The coronavirus pandemic is leading to a new phenomenon: a migration to “gateway communities,” or small towns near major public lands and ski resorts as people’s jobs increasingly become remote-friendly. This is straining the towns’ resources and putting pressure on them to adapt.

There has been a drastic increase in remote work since March, when the pandemic hit the U.S. Nearly 60% of employees are now working remotely full or part time, according to a recent Gallup poll. Nearly two-thirds of employees who have been working remotely would like to continue to do so, according to that same poll. That would seemingly give workers a lot more flexibility when it comes to where they call home.

For more than two decades, working from home or on the road was how I earned my living. Piece of cake. Portable computers became as important a piece of hardware as a reliable car. The road stuff I adapted to aren’t even a problem for the growing number of folks who can do everything they need – from home.

Most institutional workplace “experts” think the overwhelming majority of folks working remotely will rush back to the office habitat. Even a cynic like me doesn’t agree. The social and personal culture of an enforced collective workplace ain’t a kibbutz by any stretch of the imagination.

Breastfeeding moms with COVID-19 pass antibodies to their Babies

Breastfeeding women with COVID-19 don’t transmit the SARS-CoV-2 virus through their milk, but do pass on milk-borne antibodies that can neutralize the virus, a new study indicates.

Researchers analyzed 37 milk samples submitted by 18 women diagnosed with COVID-19. None of the milk samples contained the virus, while nearly two thirds of the samples did contain two antibodies specific to the virus.

Critically, the findings provide evidence that COVID-19 positive mothers should not be separated from their newborn children. At the onset of the pandemic, major health organizations provided contradictory advice on the necessity of separation was necessary.

You’ll find the details of the study over here. Good news, sound science, is always worth checking out.

Is this a brand worth buying?

With extremely rare exception, I watch Fox NOTHING! If they approached reasonable humanity, someday, in the political management of their content, I’d consider changing my attitude. Of course.

There is also no shortage of great sports programming, short fiction, long-form film-making, musical entertainment…you name it…to be found within the multiplicity of channels streaming from watchable sources available damned near everywhere. More than I can keep up with.

So, screw the pricks sucking up advertising dollar$ that benefit the current and future waves of fascist, racist, bigoted ideology that keeps the shit-end of human beings from being as poverty-stricken as their hearts and cruel minds.

The coronavirus vaccines have surpassed expectations

The big picture: The pandemic isn’t over. There are still big threats ahead of us and big problems to solve. But for all the things that have gone wrong over the past year, the vaccines themselves have shattered even the most ambitious expectations.

The vaccines represent a “stunning scientific achievement for the world … unprecedented in the history of vaccinology,” said Dan Barouch, an expert on virology and vaccines at Harvard, who worked on the Johnson & Johnson vaccine…

Most importantly, all the leading vaccines work extremely well.

All four vaccines or vaccine candidates in the U.S. — from Pfizer, Moderna, AstraZeneca and Johnson & Johnson — appear to prevent coronavirus deaths, and to offer total or near-total protection against serious illness.

RTFA. Engage with scientific facts and practice. Please, please, don’t wander off into the pop culture of profiteers, economic and ideological, who seek to line their pockets by encouraging fear and foolishness.

Runaway train saved by whale!

A fatefully placed whale sculpture in the Netherlands saved a careening train from certain devastation Monday, catching the lead runaway metro carriage on the graceful arc of its mammoth tail.

The improbable incident unfolded at the De Akkers metro station in Spijkenisse just after midnight. Photos from the scene suggest that the train, part of the Rotterdam Metro network, had been unable to stop as it reached its terminus and overran the track.

Rather than fall more than 30 feet to the ground, the train was brought to a stop by one of two whale tail sculptures at the end of the track. The driver of the train was able to escape. He visited a hospital as a precautionary measure, according to local media reports.

Authorities plan on removing his undershorts from the driver’s seat in a week or two.
