  1. World's smallest particle accelerator is 54 million times smaller than the Large Hadron Collider — and it works Harry Baker Sun, October 29, 2023 at 4:36 AM CDT·3 min read 0 A small, thin silver column sits on the face of a dime. Scientists recently fired up the world's smallest particle accelerator for the first time. The tiny technological triumph, which is around the size of a small coin, could open the door to a wide range of applications, including using the teensy particle accelerators inside human patients. The new machine, known as a nanophotonic electron accelerator (NEA), consists of a small microchip that houses an even smaller vacuum tube made up of thousands of individual "pillars." Researchers can accelerate electrons by firing mini laser beams at these pillars. The main acceleration tube is approximately 0.02 inches (0.5 millimeter) long, which is 54 million times shorter than the 16.8-mile-long (27 kilometers) ring that makes up CERN's Large Hadron Collider (LHC) in Switzerland — the world's largest and most powerful particle accelerator, which has discovered a range of new particles including the Higgs boson (or God particle), ghostly neutrinos, the charm meson and the mysterious X particle. The inside of the tiny tunnel is only around 225 nanometers wide. For context, human hairs are 80,000 to 100,000 nanometers thick, according to the National Nanotechnology Institute. In a new study, published Oct. 18 in the journal Nature, researchers from the Friedrich-Alexander University of Erlangen–Nuremberg (FAU) in Germany used the tiny contraption to accelerate electrons from an energy value of 28.4 kiloelectron volts to 40.7 keV, which is an increase of around 43%. It is the first time that a nanophotonic electron accelerator, which was first proposed in 2015, has been successfully fired, the researchers wrote in a statement. (Researchers from Stanford University have already repeated the feat with their mini accelerator, but their results are still under review). "For the first time, we really can speak about a particle accelerator on a [micro]chip," study co-author Roy Shiloh, a physicist at FAU, said in the statement. The LHC uses more than 9,000 magnets to create a magnetic field that accelerates particles to around 99.9% of the speed of light. The NEA also creates a magnetic field, but it works by firing light beams at the pillars in the vacuum tube; this amplifies the energy in just the right way, but the resulting energy field is much weaker. The electrons accelerated by the NEA only have around a millionth of the energy that particles accelerated by the LHC have. However, the researchers believe they can improve the NEA's design by using alternative materials or stacking multiple tubes next to one another, which could further accelerate the particles. Still, they will never reach anywhere near the same energy levels as the big colliders. That may be no bad thing, given the main goal of creating these accelerators is to utilize the energy given off by the accelerated electrons in targeted medical treatments that can replace more damaging forms of radiotherapy, which is used to kill cancer cells. "The dream application would be to place a particle accelerator on an endoscope in order to be able to administer radiotherapy directly at the affected area within the body," study lead author Tomáš Chlouba, a physicist at FAU, wrote in the statement. But this is still a long way off, he added.
  2. Never liked the taste of Bear meat, not even the Jerky.
  3. Yeah I had Shingles, never had the shot, kinda bad on the inside of my right leg, treated it myself with 50/50 Ammonia and water, went away in about 2 1/2 weeks.
  4. 1 guy got it real bad on his face near his left eye, the other had it on his back
  5. That's what food shelves are for..
  6. About 3-4 years ago 2 locals i know well got shingles within a month after getting the Shingles vax.
  7. COVID-19 treatments to enter the market with a hefty price tag The COVID-19 treatments millions of have taken for free from the federal government will enter the private market next week with a hefty price tag ByAMANDA SEITZ Associated Press October 27, 2023, 2:00 PM FILE - Doses of the anti-viral drug Paxlovid are displayed in New York, Aug. 1, 2022. The COVID-19 treatments millions of have taken for free from the federal gov...Show more The Associated Press WASHINGTON -- The COVID-19 treatments millions of Americans have taken for free from the federal government will enter the private market next week with a hefty price tag. Pharmaceutical giant Pfizer is setting the price for a five-day treatment of Paxlovid at $1,390, but Americans can still access the pills at no cost -- for now. The less commonly used COVID-19 treatment Lagevrio, manufactured by Merck, also will hit the market next week. Millions of free, taxpayer-funded courses of the pills will remain at pharmacies, hospitals and doctor's offices across the country, U.S. Health and Human Services officials said Friday. People on private insurance may start to notice copays for the treatments once their pharmacy or doctor's office runs out of the COVID-19 treatments they received from the government. The U.S. government initially inked a deal with Pfizer to pay more than $5 billion for 10 million courses of Paxlovid in 2021. Under a new agreement, reached last month between Pfizer and the federal government, people on Medicaid, Medicare or those who are without medical insurance will not pay any out-of-pocket costs for the treatment through the end of next year. Pfizer will also offer copay assistance for the treatment through 2028. The Department of Veterans Affairs, the Department of Defense and Indian Health Service will still be able to access Paxlovid the government has on hand. The government will also get 1 million treatment courses to keep in its stockpile. Suppliers to pharmacies, doctor’s offices and hospitals can begin ordering the treatments from the drug companies starting next week. “Pfizer is committed to a smooth commercial transition and is working collaboratively with the U.S. government and health care stakeholders to ensure broad and equitable access to this important medicine for all eligible patients,” the company said in an emailed statement to The Associated Press. Paxlovid has been used to treat COVID-19 since 2021, but the Food and Drug Administration granted full approval earlier this year for it to be used on adults with coronavirus who face high risks of hospitalization or death. That group typically includes older adults and those with medical conditions like diabetes, asthma and obesity. Full-year revenue for Paxlovid and Pfizer's COVID-19 vaccine, Comirnaty, is expected to be approximately $12.5 billion. Merck has not confirmed a list price yet for its Lagevrio treatment but said in a statement to AP that it will also offer the treatment free to patients “who, without assistance, could not otherwise afford the product.” — Associated Press reporter Tom Murphy in Indianapolis contributed to this report.

  11. I also have Elk and Moose, & Deer love all 3.
  12. I think you just don't know how to make it.
  13. In my case I need the small chips to cover a section of drain tile to prevent freezing. I have 55 Maples in the area I mow so plenty of leaves. I live in the National Forest.
  14. I love Venison, Native American here showed wife how to make it the best.
  15. I chop 'em up to 1/2" pieces first with Gator Blades then bag them with my 54" Rider.
  16. Should have shot her in 'Nam.
  17. Just put a mulching plate on your mower and chop 'em up.
  18. Have had good luck with Generals and Coopers, not so good with anything Goodyear.
  19. Years back (1991 ish) local guy here downed a Whitetail with a 17 cal..
  20. I've shot several with my Model 70 22/250.
  21. I have a Belgian Browning 7 mm.
