In addition, a 2020 analysis in The Lancet found that compared to Covid patients who weren’t in intensive care, those who were critically ill in the ICU and died had higher VWF antigens in their blood.Īnd guess what: People with Type A blood have higher levels of VWF naturally than people with type O blood, Dr. And clotting issues-including strokes, kidney failure, and pulmonary embolisms-come up a lot with Covid infections. Your body then releases von Willebrand factor, or VWF, into your blood so it can fix the damage to the vessel walls. We know the Covid virus damages the lining of your blood vessels. These Type A antibodies might make it more difficult for SARS-CoV-2 to attach to its receptor in Type O blood and multiply in the body, he explains.īut there’s another interesting layer to a potential protective element in Type O blood: something called von Willebrand factor, which is a glycoprotein in charge of repairing damage to blood vessels by prompting your blood to clot. ![]() “If you’re type O, you naturally make antibodies against Type A and Type B,” Dr. The difference may be the type of antibodies we produce depending on blood type. Either way, that would color how likely you are to not only get the virus but also how strong your symptoms are, he explains. ![]() It may affect your immune system’s strength or your inflammatory response to the infection. The most basic idea is that blood type might influence a person’s ability to fight the virus, says David Aronoff, M.D., director of the division of infectious diseases at Vanderbilt University Medical Center in Nashville. We don’t know why people with Type O might possibly be more protected-but there are a lot of theories. I don't think that having Type A or Type B is the problem-it's just that they don't have Type O," says Mark Udden, MD, professor of hematology and oncology at Baylor College of Medicine in Houston. "It's pretty clear that Type O is protective to some degree. Yet no research so far has been able to pin down the molecular goings on that explain the mechanism behind why this might be so. Where are we now, in 2022, on blood type and Covid? Additional research and review papers have confirmed that we're in more or less the same place: It looks like there really is an association between Type A blood and susceptibility to Covid and Type O blood and less susceptibility. Then, a study published in the New England Journal of Medicine confirmed the idea with a peer-reviewed study: Folks with Type A blood were 45 percent more likely to become infected with Covid than those with other blood types, while those with Type O were 35 percent less likely. Even DNA testing company 23andMe tapped their customers and found that among 750,000 people who were diagnosed and hospitalized for Covid (this was prior to vaccines), those with type O were more protected. Researchers in China first shared this idea in March 2020, and the findings were echoed by a paper out of Columbia University a month later. That year, research in the journal PLOS Genetics revealed that people with Type A blood are more likely to have a severe case of Covid-19.Ī previous study in the journal Blood Advances from 2020 also affirmed this research, adding that people with Type O blood seem to be more protected from Covid. In 2020, scientists started talking about a link between blood type and Covid. Additional research has buttressed the possibility of a link.īut let's back up first. That link was established pretty early on in the pandemic and scientists didn't let it go. But the seemingly-banal detail might be a factor in who is most susceptible to Covid 19. In fact, most people don’t even know whether they’re Type A, B, AB, or O. Blood type doesn’t affect much in our daily lives.

It’s not bad by any means, but Unread 2 is simply way cleaner and nicer to use. Probably the biggest drawback to NetNewsWire is its overall design. If you use your iPad with a keyboard, you’ll be happy. A toolbar provides easy access to create new folders, mark whatever is selected as read (including the must-have “mark all” option), star favorites, or open links in your preferred browser. NetNewsWire has good keyboard support and syncs fast. Feeds can be organized into folders, and NNW5 features Smart Feeds, which automatically sorts articles into Today, All Unread, and Starred views for easier consumption. If you’re at all familiar with RSS readers, the UI layout here isn’t much different: Subscriptions appear at left, your list of feeds in the middle, and the selected article displayed in the larger portion of the window at right.

Snapshots are one of many improvements we’re making to improve your experience with Heroku Data Services. But clearly, this process was not built for speed, so we made it better! Feedback Welcome You can read more about this backup and restore methodology in our Dev Center article on Heroku Postgres Data Safety and Continuous Protection. ![]() The combined processes of base backups and WAL record changes means it can take a long time to upload when new backups are made, and a long time to restore, which includes downloading the base backup from servers and replaying WAL record changes between base backups. To replay or restore a PostgreSQL service, we used to restore from a base backup first, then replay the WAL previously archived until the closest possible restore point is achieved. These are smaller pieces of data that reflect changes to a database on a low level. WAL records are changes to the database that can be archived elsewhere, using WAL records.This is a copy of the full existing state of the database at the time it was taken. Base backups are required when a database is first created.WAL-E is a convenience wrapper for the two conceptual parts required for disaster recovery in a PostgreSQL world: In the past backups of Heroku Postgres relied on a WAL-E for primary backup and restoration. The Old Way: Backups Was Not Built for Speed Restoring to a snapshot that is closest to the transaction we want to restore to means less WAL replay, and a lower mean-time-to-restore. For databases that change more frequently, however, we capture more frequently. For average or low change databases we try to capture at least every 24 hours. Now with Snapshots, the rate at which we capture is dynamic. Overall, this means restoring a database is much faster now. Snapshots are faster than base backups, occur at the storage level, and are incremental so we can take them more frequently. The gap in HA availability during failovers or follower promotion that used to take anywhere up to 12 hours now takes under 15 minutes.Forks and followers creation that used take sometimes up to 24 hours, now can take under 30 minutes. ![]() ![]() WAL replay from that point is still as before (using WAL-E). When we restore, we restore instances using the last snapshot taken. We now take snapshots in place of base backups. In November 2020 we introduced a performance improvement to our physical backup and restore functionality for our Heroku Postgres customers. This makes the creation of forks and followers, and restoring the database, faster than ever, at no additional charge. In the past forks and follows of a Premium-8 test database with 992 GB of data took 22 hours now with Snapshots, the same process is reduced to 10 minutes. We’ve been hard at work focused on improving performance, speed, and capacity for the Heroku Data services you rely on. Today, we’re thrilled to announce backups of Heroku Postgres are now 40x faster by leveraging Snapshots in place of base backups.

This suggests they are being acted on by the gravitational force of an unseen object, almost always a planet. One way to do that is to observe when stars move slightly on regular cycles for no reason we can see. With rare exceptions, the light from these is so overwhelmed by the star itself that we can’t see them directly with existing equipment, so have to get creative. However, the shift will be larger where the away movements combine than where the two motions counteract each other.Ī particularly important application is in finding exoplanets (planets orbiting other stars). If the whole object is also moving relative to us, such as a galaxy moving away, we may be seeing a redshift on both sides. We measure the rates at which galaxies and the accretion disks around black holes, among other things, are turning by detecting the redshift on the side turning away from us, and the blue on the limb moving towards us. Measuring the universe is a pretty big deal (technically the biggest deal there is), but it’s not the only way in which redshift has transformed astronomy, although in the other cases it needs some help from blueshift. Although this measures speed not distance, on a grand scale these two correlate so well that redshift becomes the most reliable measure. Outside our local patch of the universe, the distances to galaxies are measured by the extent to which their light has been redshifted, represented by the letter z. If they’re in the infrared, it’s moving away fast. If we find that pair at yellow wavelengths, we know the source is coming towards us. Some of these patterns, such as orange double lines produced by sodium, are easy to recognize even when they have been shifted to substantially different wavelengths. Image credit: Georg Wiora (Dr Schorsch) via Wikimedia Commons ( CC-BY-SA 3.0) However, once hot enough to become gases, the light released has extra intensity at certain wavelengths specific to the elements present. Hubble noticed the redshift because some of the galaxies he was studying were traveling away from us very fast indeed – not close to the speed of light, but enough to cause a noticeable bunching.įortunately, to measure red- (or blue-) shift astronomers don’t have to rely on looking at an object and asking, “Does that look a bit pink to you?” When heated, objects give off a broad spectrum of electromagnetic radiation. ![]() That’s why, despite the physicists’ jokey bumper sticker reading, “If this sticker looks blue you’re traveling too fast”, we hear, but don’t see, the Doppler effect in our everyday lives Scaling the universe However, because light in a vacuum travels almost a million times faster than sound in air, it is necessary for a source to be moving very fast before the shift is noticeable. When the waves spread out they are referred to as “redshifted”. The same bunching on approach and spread on departing occurs. Light also travels in waves, with red light having longer wavelengths than blue. ![]() These are deployed to jump on floating platforms, swim through spike-filled rivers, and sail past great pits – each more dangerous than the last.

Some problems have more than one step, so it is important that you check to make sure the answer you choose answers the question posed in the problem. One way to do this is to underline important information and questions. Be sure to recognize each part of the question, and let those parts help you make a plan to solve the problem. This may seem like a simple concept-but it is too easy, in a testing situation, to answer one part of a question and assume that the problem is finished.
