Scientists at the University of North Carolina have confirmed that effective protection against the SARS-CoV-2 coronavirus is short-lived. The results of the study are published in the journal Proceedings of the National Academy of Sciences (PNAS).
It is known that the risk of breakthrough infections, in which a person becomes infected despite vaccination, depends on the type of vaccine. Current mRNA vaccines (Pfizer, Moderna) provide the longest duration of protection, nearly three times the duration of the immune response after natural infection, as well as after the Johnson & Johnson and Oxford-AstraZeneca vaccines.
According to the authors of the article, mRNA vaccines provide the highest level of antibodies, which is associated with more reliable protection. However, for a long-term effect against COVID-19, additional stimulation with booster doses of vaccines is required, which promotes antibody responses to new strains of coronavirus that appear during natural evolution over time.

They just don't want to tell you that each new booster makes huge hit on immune system and depletes its reserves.

A recent report from the Fusion Industry Association (FIA) makes it clear that funding for commercial fusion programs has accelerated significantly over the past 12 months. An increase in the flow of funds into the development of commercial fusion reactors directly signals an increase in investor confidence, which gives hope for a mature solution within the next 20 years.
According to an FIA survey of industry participants, in the last year by the time of the report, private fusion funding has increased by 139% to $2.83 billion. ”, said Andrew Holland, CEO of the Fusion Industry Association.
Of the surveyed companies in the sector, 93% are confident that fusion reactors will begin commercial electricity generation in the 2030s. A year ago, a smaller number of respondents shared this confidence - 83%. At the same time, 84% of respondents believe that a thermonuclear plant will demonstrate a sufficiently low cost and high efficiency to be considered commercially viable in the same time frame.
No one will tell you that this guys promised working reactors in 1980s, 1990s, 2000s, 2010s, 2020s. And will go on and on and on.

The World Health Organization held a regular meeting of the International Health Regulations emergency committee in connection with the COVID-19 pandemic. The Committee expressed concern about the sharp decline in testing people for covid in many countries, which leads to a decrease in the coverage and quality of surveillance. Together with the conclusion of the committee, WHO published the recommendations of the director general of the organization. He calls for the use of all measures that have previously been developed to reduce the spread of the virus. For example, wearing well-fitting masks, social distancing, isolating while sick, washing hands frequently, avoiding closed spaces with poor ventilation, crowded places.
The WHO also recommends that countries prepare to rapidly scale up health and social measures in response to changes in the virus and population immunity, as COVID-19 can still overwhelm public health capacity and result in deaths. In addition, the large number of coronavirus patients is jeopardizing the ability of healthcare systems to treat other acute and chronic conditions.
At least a dozen Z-mount lenses and accessories are getting a price increase here in the US. The most significant of those will be the f/2.8 zoom trio, each of which gets a US$100 increase. All the DX lenses get a US$10 to US$30 price increase. A few other lenses get US$10 to US$50 increases as well.
Nikon claims that the increases are necessary due to cost increases in component parts and some logistics (basically shipping for those parts between plants and getting products to subsidiaries in a timely fashion).
Europe and several other parts of the world had already seen price increases from Nikon, but the strength of the US dollar probably helped stall the need for them in North America. The irony, of course, is that many of the products showing price increases were just on an instant rebate program, which probably drove demand up, and then you need to build more and that costs more...
