Will Vaccines Work Against New Variants Of The Coronavirus? The rollout of COVID-19 vaccination programs around the world has been anything but smooth. Complicating the effort is the virus itself. The original coronavirus genome that the current vaccines were based on has mutated. Now, there are three virus variants, and experts are somewhat concerned. How will the vaccines scientists have worked so hard to make fare against these three variants, and future ones? Stephen Goldstein, post-doctoral

A Skeletal Record Of Medieval England Society If you’ve ever fractured a bone, that skeletal trauma stays with you forever, even after it heals. So researchers across the pond are using bones from medieval times to put together a picture of what life was like. The bones in the study came from ordinary people in medieval Cambridge in the United Kingdom, from between the 10th and 14th century. The researchers found that you can often guess who was working class, and who had more money based on what

Everything You Want To Know About COVID-19 Vaccines The U.S. has been vaccinating people against COVID-19 for a little over a month. While there have been plenty of hiccups, over 20 million people in the country have received at least one dose of either the Pfizer-BioNTech or the Moderna shots. For the past few weeks, Science Friday has been collecting your questions about the COVID-19 vaccines on the SciFri VoxPop App—and we heard from a lot of listeners. The questions and concerns ranged from if

Orange Is The New Black—For Bats For a newly-described bat from West Africa, dubbed Myotis nimbaensis (mouse-eared bat from the Nimba Mountains), scientists are reaching for a different part of the color wheel. While Myotis does have some black on its body, the overwhelming majority of the bat’s fur is bright orange. A team of scientists from the American Museum of Natural History and Bat Conservation International stumbled on the new species while surveying populations of another endangered bat

After Flint’s Crisis, An Algorithm Helps Citizens Find Lead Pipes It’s been nearly seven years since the beginning of Flint, Michigan’s water crisis, when high levels of lead from corroded lead pipes led to water shortages and health issues for city residents. Since then, many other cities around the country have had their own problems with lead. Researchers estimate that millions of Americans are living with pipes that need to be replaced. As Wired reported earlier this month, Toledo, Ohio is one

How The West Is Battling COVID-19 And Valley Fever For the past year, the COVID-19 crisis has taken up much of our attention. But the pandemic can come with complications: Some states face an onslaught of pre-existing diseases. In the American West, doctors, scientists, and patients continue to battle valley fever, a respiratory illness caused by breathing in the fungus Coccidioides. In desert hot spots, communities are now facing what doctors at Kern Medical’s Valley Fever Institute in Bakersfield,

How Did A Vaccine Get Developed In Less Than A Year? From the first discovery of a strange new respiratory virus in Wuhan, China, in January of 2020, it took less than a year to get a vaccine into the arms of frontline healthcare workers. More than two dozen vaccine candidates have made it from basic safety trials to Phase 3, where efficacy against COVID-19 is tested. That’s particularly remarkable as before the pandemic, it was rare for a vaccine to take fewer than 5 years from start to

The U.S. has now administered roughly five million doses of COVID-19 vaccines, far behind the nation’s goal of vaccinating 20 million by the end of 2020. The two approved COVID-19 vaccines, one from Pfizer and one from Moderna, are intended to be given over the course of

Finding New Particles On The Frontier of Physics As a theoretical physicist, Frank Wilczek has made a career out of dreaming up new ways to understand our physical universe—and he’s usually right. In the early 1980’s, he predicted the existence of a new quasiparticle, called the anyon—which was confirmed in experiments last summer. In 2004, Wilczek was awarded the Nobel Prize in Physics for his contribution decades earlier to the theory of quantum chromodynamics. And in addition to the anyon, he

Where Did The Word ‘Vaccine’ Come From? As we head into 2021, there’s one word on all of our minds: Vaccine. It may be in headlines right and left these days, but the word was actually coined more than a century ago. In the 1700s, smallpox seemed unbeatable. People tried all sorts of things to protect themselves, from taking herbal remedies to tossing back 12 bottles of beer a day. Nothing worked. Then Edward Jenner, an English doctor, heard a rumor about a possible solution. It wasn’t a cure,

Nature’s Own Holiday Light Show The spectacular glowing green of the Northern Lights is caused by charged particles from the solar wind interacting with gas molecules, atoms, and ions in the atmosphere. Protons and electrons streaming from the sun follow the Earth’s magnetic field lines, accelerating down towards the poles. The aurora process is similar to a neon sign—the charged particles excite atmospheric gas, causing it to emit light. Don Hampton, research associate professor in the

How The Past Hints About Our Climate’s Future Ask a climate scientist how much the earth will warm as a result of the carbon dioxide we’re emitting right now, and the answer will be a range of temperatures: likely anywhere from 1 to 5 degrees Celsius. But all the models we have to predict the future are based on data from the past, most of it collected in the last 140 years. As carbon dioxide rises further past the unprecedented-in-human-history 400 parts per million (ppm), we are increasingly in a

She received a first dose of the vaccine made by Pfizer and BioNTech, and will require a second dose in several weeks to achieve the full effect.

So far, only a handful of cases of COVID reinfection have been confirmed, but we don’t yet know the true rates. Cases could be missed if the first or second infection is asymptomatic, and sometimes, what looks like a case of reinfection is something else entirely. Over the past few months, we’ve seen both concerns that
