Scientists at the Victor Chang Cardiac Research Institute in Sydney have discovered a critical new gene that it is hoped could help human hearts repair damaged heart muscle after a heart attack.

Researchers have identified a genetic switch in zebrafish that turns on cells allowing them to divide and multiply after a heart attack, resulting in the complete regeneration and healing of damaged heart muscle in these fish.

It's already known that zebrafish can heal their own hearts, but how they performed this incredible feat remained unknown, until now. In research recently published in the prestigious journal, Science, the team at the Institute drilled down into a critical gene known as Klf1 that previously had only been identified in red blood cells. For the first time they discovered it plays a vital role in healing damaged hearts.

Dr. Kazu Kikuchi, who led this world first research, said he was astonished by the findings.

"Our research has identified a secret switch that allows heart muscle cells to divide and multiply after the heart is injured. It kicks in when needed and turns off when the heart is fully healed. In humans where damaged and scarred heart muscle cannot replace itself, this could be a game-changer," Dr. Kikuchi explains.

Cloth face masks during exercise limit performance and physical capacity, study finds

Heart rate peaks lower and oxygen intake drops, according to sports science research

Cloth face coverings limit performance and physical capacity during exercise, a new study has found.

Masked joggers said they felt claustrophobic during higher-intensity exercise and their oxygen intake was reduced, according to research.

Heart rate was found to have a lower peak while exercising with a mask and participants could not keep up a jog for as long as when unmasked.

Comment: Note that this study was done on healthy adults, the damage wearing a mask inflicts on people who already suffer low oxygen levels will be worse because the brain can only be starved of so much oxygen before damage is incurred. It's also likely that the detriment to health isn't limited to just those who exercise, with regular mask wearing the harm may be low level but cumulative:

Objective:Health - Papers Please! Vaccine Passports and the Death of Human Liberty

O:H header
The looming threat of vaccine passports have been a constant companion over the past year, sending chills down the collective spines of anyone with even the slightest value of liberty. While a large scale rollout is still on the horizon, we are starting to see these things issued in various places, and they're pretty much exactly what everyone has feared.

While New York State's voluntary app has proven to be a logistical nightmare, with its many shortcomings making it almost unusable, Israel's Green Pass has already started to create a two-tiered society, with stark contrast between the haves and the have-nots (vaxxed and unvaxxed) and Naomi Wolf is sounding dire warnings about "the end of human liberty in the West if this plan unfolds as planned."

Yet the plans of the elites are not without resistance. Gov. DeSantis of Florida has taken an executive action against vaccine passports and even the WHO has dismissed the idea as discriminatory. Meanwhile, the UK has said that the Covid passports will only be a 'short-term' measure until the covetted herd immunity has been reached (if you trust them on this, you might want do a little research into the history of 'temporary' government powers).

U.K. variant isn't linked to more severe disease or death, study finds

People infected with the more contagious coronavirus variant first identified in the United Kingdom did not experience more severe symptoms and were not at higher risk of death, according to a new study published Monday.

Scientists are struggling to pin down the nature of the U.K. variant, which has become the dominant strain across Europe and, as of last week, in the United States. Chief among the questions: Is the variant more deadly?

The study, published in The Lancet Infectious Diseases, looked at data from last fall in the U.K., shortly after the variant was first detected. It soon spread rapidly, eventually becoming the dominant strain circulating in the country.

The new findings add to scientists' ever-evolving understanding of the U.K. variant, known as B.1.1.7, at a crucial time in the pandemic, as it and other variants are circulating widely in other countries.

Researchers looked at Covid-19 patients who were admitted to University College London Hospital and North Middlesex University Hospital from Nov. 9 to Dec. 20. The scientists sequenced virus samples from 341 patients, finding that 58 percent were positive for the U.K. variant and that 42 percent had been infected with a different strain.

The researchers then compared the severity of symptoms between the two groups and found that patients infected with the B.1.1.7 variant were not at increased risk of becoming severely ill or dying. The study zeroed in on a time when the U.K. variant was just gaining a foothold in London — and as the U.K.'s vaccination program was getting underway.

More blood clots: US govt pauses rollout of Johnson & Johnson COVID-19 vaccine


Comment: How many blood clots, cytokine storms, and anaphylactic reactions will it take for people to stay away from these things?

U.S. federal health agencies on Tuesday recommended pausing the use of Johnson & Johnson's COVID-19 vaccine for at least a few days after six women under 50 given the shot developed rare blood clots, dealing a fresh setback to efforts to tackle the pandemic.

Following the news, Johnson & Johnson (J&J) said it was delaying the rollout of the vaccine to Europe, a week after regulators there said they were reviewing rare blood clots in four recipients of the shot in the United States.

Janet Woodcock, acting commissioner of the U.S. Food and Drug Administration (FDA) said the agency expected the pause to be a matter of days, and it was aimed at providing information to healthcare providers so they can diagnose, treat and report such blood clots.

Comment: How is it not common sense that injecting foreign material into a human body is not a good idea?

Three Things Most People Don't Know About Physician-assisted Death

The cadence is increasing of jurisdictions introducing, normalizing and expanding laws allowing doctors to help people commit suicide.

Is this purely in the service of relieving unbearable physical or mental suffering? Or do other factors predominate?

I used to believe the former, but my recent re-examination of the issue suggests the latter is more likely.

Israel COVID-19 study finds South Africa variant able to 'break through' Pfizer vaccine

virus
A new study from Israel indicates the South Africa variant of the coronavirus can "break through" the Pfizer/BioNTech vaccine to some degree.

A team from Tel Aviv University and Clalit Health Services found that the prevalence of the South Africa variant among patients who received both doses of the vaccine was around eight times higher than those unvaccinated - 5.4% versus 0.7%.

The study compared over 400 people who received at least one shot of the vaccine and contracted the coronavirus with the same number who were infected and unvaccinated.

"We found a disproportionately higher rate of the South African variant among people vaccinated with a second dose, compared to the unvaccinated group," said Tel Aviv University's Adi Stern. "This means that the South African variant is able, to some extent, to break through the vaccine's protection."

The Pentagon's Defense Advanced Research Projects Agency (DARPA) is working on a COVID vaccine that will work on all variants and has developed an implantable microchip that it says will continuously monitor the human body for signs of the virus.


Retired Colonel Matt Hepburn, an army infectious disease physician heading up DARPA's response to the pandemic, appeared on 60 Minutes to demonstrate the technology.

Holding up a vial of green tissue-like gel, which contains the chip, Hepburn proclaimed "You put it underneath your skin and what that tells you is that there are chemical reactions going on inside the body, and that signal means you are going to have symptoms tomorrow."

"It's like a 'check engine' light," Hepburn added, noting that those with the chip "would get the signal, then self-administer a blood draw and test themselves on site."

"We can have that information in three to five minutes," Hepburn continued, adding "As you truncate that time, as you diagnose and treat, what you do is you stop the infection in its tracks."

Masks are a ticking time bomb

Toxic Masks
The planet may be facing a new plastic crisis, similar to the one brought on by bottled water, but this time involving discarded face masks. "Mass masking" continues to be recommended by most public health groups during the COVID-19 pandemic, despite research showing masks do not significantly reduce the incidence of infection.1

As a result, it's estimated that 129 billion face masks are used worldwide each month, which works out to about 3 million masks a minute. Most of these are the disposable variety, made from plastic microfibers.2

Ranging in size from five millimeters (mm) to microscopic lengths, microplastics, which include microfibers, are being ingested by fish, plankton and other marine life, as well as the creatures on land that consume them (including humans3).

Children and young people are bearing the brunt of the mental health crisis caused by the pandemic, new analysis by the Royal College of Psychiatrists has found.

A year on from the first lockdown and after warnings from the mental health sector about the impact of the pandemic on the country's mental health, NHS Digital data shows that while the crisis is affecting people of all ages, it is under-18s who are suffering most.
