Fully vaccinated people don’t need to wear a mask or physically distance during outdoor or indoor activities, large or small, federal health officials said, the fullest easing of pandemic recommendations so far.

The fully vaccinated should continue to wear a mask while traveling by plane, bus or train, and the guidance doesn’t apply in certain places like hospitals, nursing homes and prisons, the U.S. Centers for Disease Control and Prevention said Thursday.

The agency said it was making the revisions based on the latest science indicating that being fully vaccinated cuts the risk of getting infected and spreading the virus to others, in addition to preventing severe disease and death.

Physicists have measured the “skin” of an atom for the first time and, perhaps unsurprisingly, it is extremely thin. The measurement may help us understand the properties of neutron stars.

Lead-208, an isotope that contains 82 protons and 126 neutrons, has a type of nucleus that physicists refer to as “doubly magic” because both the protons and the neutrons are arranged neatly into shells inside the nucleus. These shells keep the atom relatively stable and make it simpler to experiment on, so when the PREX collaboration at the Thomas Jefferson National Accelerator Facility in Virginia set out to measure neutron skin, they opted to experiment on lead-208.

Within the Milky Way, there are an estimated 200 to 400 billion stars, all of which orbit around the center of our galaxy in a coordinated cosmic dance. As they orbit, stars in the galactic disk (where our Sun is located) periodically shuffle about and get closer to one another. At times, this can have a drastic effect on the star that experience a close encounter, disrupting their systems and causing planets to be ejected.

Knowing when stars will make a close encounter with our Solar System, and how it might shake-up objects within it, is therefore a concern to astronomers. Using data collected by the Gaia Observatory, two researchers with the Russian Academy of Sciences (RAS) determined that a handful of stars will be making close passes by our Solar System in the future, one of which will stray pretty close!

The study was conducted by Vadim V. Bobylev and Anisa T. Bajkova, two researchers from the Pulkovo Observatory’s Laboratory of Galaxy Dynamics in St. Petersburg, Russia. As they indicated, they relied on astrometric data from the Gaia mission’s Early Data Release 3 (EDR3), which revealed kinematic characteristics of stars that are expected to pass within 3.26 light-years (1 Parsec) with the Solar System in the future.

Difficulty swallowing after a Stroke occurs when the esophagus becomes damaged or the muscles and nerves that control swallowing are functioning poorly. There can also be a blockage in the esophagus, which is making it difficult to swallow. It will hurt when you try to swallow. Since it’s painful, it may cause you to not want to eat. This can cause other issues to occur in your body, such as weight loss. At Rehab, a nurse explained to me that my swallowing problem was caused by weak muscles in the esophageal sphincter. That information stimulated me to create my own therapy for the esophageal sphincter. I wrote out the transcript for the therapy, and a lady named Collette read it into a recorder. I listen to the recording several times a day. My swallowing problems resulted in a feeding being inserted up my nose. The therapy makes it possible for me to eat oatmeal, grits, eggs, pasta & beef, and corn flakes. After passing the swallowing test last Friday, the Speech Pathologist sent me to the Emergency Room, where they pulled the feeding tube from my nose.

This can cause other issues to occur in your body, such as weight loss. When it comes to finding out what is causing the difficulty in swallowing, there are a number of reasons why it’s happening. Some reasons you can’t help, while others are simple.

Certain things that we do to our bodies could trigger our inability to swallow. Once you know what is causing the issue, it’ll be easier for you to swallow. Sometimes it is things you can do at home, while others need to be treated by a medical professional.

A new study published by researchers from MIT and also from Immersion Health, Portland raises the alarm about possible unintended consequences of the mRNA vaccines currently being deployed against the COVID-19 disease.

The study findings were published in the peer reviewed journal: International Journal Of Vaccine Theory, Practice And Research. https://ijvtpr.com/index.php/IJVTPR/article/view/23/29.

The Army will begin equipping units with augmented reality headsets by the first quarter of fiscal year 2022, according to Congressional testimony by two of the service’s top officials.

In written testimony prepared for the House Appropriation Committee’s defense subcommittee, Acting Secretary of the Army John Whitley and Army Chief of Staff Gen. James McConville detailed the service’s priorities as lawmakers wait for President Joe Biden’s 2022 budget request. Whitley and McConville wrote that they need continued Congressional support for rapid prototyping, development and procurement for the Integrated Visual Augmentation System, or IVAS, among other emerging programs.

“By 1QFY22, we’ll equip the first unit with IVAS,” Whitley and McConville said in their joint written testimony prepared for a Wednesday hearing. The government’s fiscal 2022 year begins in October.

They suggest that over the past millennium, the human gut has experienced an “extinction event,” losing dozens of species and becoming significantly less diverse, says lead author and Harvard Medical School microbiologist Aleksandar Kostic. “These are things we don’t get back.”

First DNA from paleofeces show people 1000 years ago in U.S., Mexico had much more diverse gut microbes.

Eight months on, the semiconductor shortage seems likely to stretch into 2022. Increasing chip production is a slow and difficult business.
