The Loh Down on Science: Special Pandemic Edition explores the science and history of pandemics (appropriate for middle school and up). Each week, fascinating new three-minute modules are reported by science writers from the Loh Down on Science "Hive." Subjects include: global crises' unexpected "silver linings" (i.e. technological innovations), what Isaac Newton did during HIS 1600's college quarantine, the science of soap, COVID-19's surprising impacts on climate change, and Folding@home, a cool new project seeking to model a coronavirus cure with the help of our home computers (it worked for Ebola!).

El tráfico en Los Ángeles está condenado a vivir en la infamia. ¿Hay algún beneficio? Con el brote de coronavirus, queda claro (nuevamente) que algunas ciudades tienen brotes más grandes. En general, las ciudades más grandes equivalen a brotes más grandes. ¿Lo curioso? ¡Las ciudades con los sistemas de transporte público más eficientes son las peores en contagiar! La buena noticia es que podemos usar esta información para atacar a los virus que van a dedo.

La mayoría de nosotros no vio venir la pandemia, pero nuestros perros pudieron ¡¿olérselo?! ¿Sabíais que las enfermedades pueden “olerse”? Las narices caninas tienen 100 mil veces más sensibilidad que las nuestras. Ya hay perros entrenados para detectar ciertos tipos de cáncer ¡e incluso la malaria! Entonces, ¿los perros también podrían oler el coronavirus?

Con tantos productos de limpieza disponibles puede resultar difícil elegir cuales son los mejores - incluso si no hubiese una pandemia. Afortunadamente, muchas de las opciones son efectivas eliminando virus. La mayor diferencia está en cómo utilizar cada producto para limpiar las superficies.

El alba. Un tiempo para amaneceres, café y pájaros extremamente ruidosos. ¿Se han vuelto más ruidosos, o se ha calmado el mundo?
Muchas teorías pueden explicar por qué nuestros amigos emplumados cantan. Y aunque parece que su coro del amanecer subió el volumen, los ornitólogos dicen que ese no es el caso. A medida que nuestro mundo se calma a un susurro, las aves tienen menos competencia. En realidad han atenuado su coro; nosotros hemos mejorado en escuchar.

Durante tiempos inciertos, la toma de decisiones razonables parece haberse esfumado.
Consumidores alrededor del mundo se abastecen para tener suficiente en su despensa...¡y que les dure años! Incluso nuestros ancestros tenían tácticas de supervivencia similares. Es posible que los sobrevivientes de la peste bubónica de Inglaterra en el siglo XVII no construyeran grandes fortalezas. Pero, acumularon lo que pudieron encontrar (¡hola, cerveza!). ¿Pero por qué?
Los psicólogos lo achacan a un mecanismo de la evolución. Hemos sobrevivido milenios cooperando en grupo. Nuestras habilidades sociales nos han traído hasta aquí. Si vemos que nuestra "tribu" se abastece, ¡también nos abastecemos nosotros! Aunque podríamos defendernos de los grandes depredadores con esta impresionante colaboración, ¡nuestras tiendas también se quedan sin papel higiénico!

La pandemia del nuevo coronavirus ha sido causada por un virus originado en animales. Si este virus puede saltar de una especie animal a otra, ¿qué evitará que ataque a nuestras mascotas? Estudios científicos sobre previas pandemias de coronavirus sugieren que los gatos ¡pueden contagiarse! Pero los científicos tampoco están muy preocupados. Aunque los coronavirus pueden infectar a gatos, no hay evidencias de que los gatos puedan pasar el virus a los humanos. Podemos dormir tranquilos - ¡si es que Fluffy me deja sitio!
Las propiedades auto-desinfectantes del cobre son conocidas y están bien estudiadas. Las bacterias y los virus no sobreviven mucho tiempo en una superficie de cobre.

La pandemia del coronavirus ha obligado a muchos al teletrabajo. Para los humanos, este tiempo ha sido muy estresante. Pero ¿cuál es la perspectiva de la Madre Tierra? Con la actividad humana reducida, los cielos se han despejado y la contaminación ha disminuido. ¡Parece que le está yendo bien al planeta! ¿Pero esto cuánto durará? Vivimos algo similar durante la Gran Recesión de los Estados Unidos en el 2008. Las emisiones de carbono bajaron porque la gente consumía menos productos. Sin embargo, cuando la economía comenzó a crecer, las emisiones subieron al máximo. La historia tiende a repetirse. Hoy, podemos anticipar un ciclo similar cuando la economía se reabra y las personas regresen a trabajar. Armados con este conocimiento, podemos tomar decisiones conscientes y sostenibles para nuestro futuro colectivo.
A medida que las personas están atrapadas en la cuarentena por el coronavirus, muchas personas han comenzado a notar un cambio en el comportamiento de sus mascotas. ¿Por qué este cambio? ¡No necesitan preocuparse por pagar recibos! Bueno, quizás tenemos la culpa. La ciencia ha descubierto que los gatos que son ansiosos, agresivos y temerosos reflejan los rasgos de personalidad de los dueños neuróticos. Los perros también se ven afectados por el comportamiento de sus dueños. A medida que aprendemos a vivir con la pandemia, ¡debemos recordar que nuestras mascotas son empáticas con nuestras emociones!
Lavarse las manos con agua y jabón durante 20 segundos se cita como la mejor práctica para protegernos del coronavirus. Por imposible que parezca, algo tan mundano como el jabón realmente es nuestra mejor defensa contra el nuevo coronavirus. De hecho, el jabón tiene una larga historia de mantenernos seguros. Esto ocurre por la composición química única del jabón, que está perfectamente equipada para destruir los virus.

Extra quaran-screen time has revived a generations-old question: do video games really rot your brain?
Experts say… not exactly! Too much of a good thing is, of course, bad. Playing games nonstop can lead to anxiety, depression, and headaches. But, in moderation, video games help our brains level up! They can help us form memories, learn strategy, and even be nicer to our families. A definite plus while everyone is stuck together!

Dawn. The time for sunrises, coffee, and extremely loud birds. Have they gotten noisier, or has the world quieted down?
Many theories can explain why our feathered friends sing. And although their “dawn chorus” seems like it got cranked to an eleven, ornithologists say that’s not the case. As our world quiets down to a whisper, birds have less competition. They’ve actually toned it down; we’ve just gotten better at listening.

Summertime sadness is taking on a new form due to quarantine. But there are steps we can take to lower our risk of exposure to coronavirus while still enjoying the outdoors! Take care to continue social distance and mask wearing, limit your time near others, and continue to wash those hands!

Vaccines take a lot of work and time. A turn around time of several years is considered fast! That is too slow to help with a pandemic that is here right now. But next generation vaccines promise something much quicker. How? With guns. Lots of guns. And by stealing the virus’s own tool to use against it!
Every year, many Muslims fast during the Islamic holy month of Ramadan. Meaning they don’t eat or drink anything from roughly before sunrise until after sunset. Ramadan of 2020 falls during the coronavirus outbreak and people are curious about the health implications. Research has shown that Ramadan fasting lowers levels of cholesterol and chemicals causing inflammation. Inflammation is normally a good thing, it’s part of our body’s natural immune response to an infection. However, too much inflammation is dangerous, so fasting may lower the potential for excessive inflammation. Another study suggests that Ramadan fasting reduces the risk of tuberculosis infection. There’s no guarantee that fasting will make you COVID free, but it’s good to know the potential impact it has on our immune system. Facts behind fasting are fascinating, try saying that five times FAST! Pun fully intended.

Viruses are everywhere, but most of them are rather harmless. An excellent example is the herpesvirus! As virologist Kennen Hutchison explains, almost all of us have a form of herpes. Chickenpox, cold sores, and shingles are all a type of herpes. Even the chickenpox vaccine means you have herpes! And once you have it, they stick around forever! But don’t freak out, because most cases of herpes don’t hurt us.

You’re wearing a mask on a walk, minding your own business, and then AHHHHHH, somebody pops up behind you, on a bicycle without a mask! No!
This is Emily Sarah Sumner with the Loh Down on Science: Special Pandemic Edition.
When you think of a mask, what do you think of? Before COVID, masks were not very commonly worn in the US. In western countries, many associated masks with robbers, masquerade balls, and surgeons.
In Eastern countries are different. For example, in South Korea and China, masks have already a part of everyday life for quite some time. Masks are thought of as polite. It is rude NOT to wear a mask when you are sick.
Masks are more than just a fashion statement. Research has shown that masks can be useful in preventing the spread of the coronavirus! If you have coronavirus, the droplets that come out of your mouth can get others sick. When you cover your mouth with a simple piece of fabric, those droplets can’t travel as far. Scarves, old t-shirts, anything will do!
Countries that are having LESS outbreaks of the coronavirus have worn masks long far before the COVID-19 even existed. Thailand, China, and South Korea all successfully flattened (for now) their curves. On the other hand, the countries hardest hit - like the US, Italy, and Brazil - did not have universal mask-acceptance prior to the virus.
Research suggests that communal mask-wearing can help stop the spread of the virus. Some places in the US have set rules for everybody to wear facial coverings when in public, like Massachusetts and New York City. However, this is not the case for the whole country. In the US, one study showed that less than HALF of people have started wearing masks since the start of this pandemic.
So I only need to wear a mask if I’m feeling sick, right? No! Research has shown that many people with the coronavirus may show no symptoms for a while.
Let’s say Justin is an asymptomatic carrier of the coronavirus and you are healthy. If Justin is NOT wearing a mask, the chance of him infecting you is high, even if you choose to wear a mask. If Justin IS wearing a mask, the chance of him infecting you is low. It’s even lower if you decide to wear a mask too. Universal mask-wearing is one of the strongest weapons we have against the coronavirus.
My mask protects you, and your mask protects me! Pretty cool, right?
My mask is your mask! Your mask is my mask! These masks were made for you and me! (And keep smiling.)
The world waits for a coronavirus vaccine. But this isn’t the first time it’s taken a little longer than ideal.
For nearly forty years, scientists have searched for a vaccine for HIV, the virus behind the AIDS epidemic. Although they’re still searching, drugs, treatment and technology have made an HIV diagnosis a little better. The good news is that coronavirus shares more in common with other viruses than a devious trickster like HIV... and it all comes down to copying skills.

Mistranslation? Awkward. Surprisingly, it was a classic mistranslation after the Franco-Prussion War that prompted the acceptance of biosafety. Now, we keep dangerous pathogens locked up tight! And their identities might surprise you…
Depending on the biosafety level, lab techs might wear special ventilation suits or even decontaminate their clothes. But these extreme measures are only used against the world’s most dangerous viruses and bacteria. Shockingly, protocols for the infamous new coronavirus aren’t as strict as they are for dangerous space rocks!

Cat got your quarantine? As people are stuck in the coronavirus induced self-quarantine, many pet owners have started noticing a shift in their pet’s behavior. Why are they being weird? They don’t need to worry about paying the bills! Well, we may be the culprits of their peculiarities. Research has found that anxious, aggressive, and fearful cats reflect the personality traits of neurotic owners. Dogs are also more responsive to their owners that are stressed than those that are calm. As we learn to navigate the stressful pandemic, we must remember that our pets are empathetic to our emotions. Next time we notice our pets acting strange, maybe we need to self-reflect!

Humans have made remarkable progress in eliminating diseases. Diseases that were once very common are no longer common today. For example, fecal-oral route diseases once plagued nearly every society in history. These diseases only go away when people practice good hygiene.

Recovered from the new coronavirus? Congratulations! It’s safe for you to go out again! Or is it?
This is Stella Moon with the Loh Down on Science: Special Pandemic Edition.
In mid-April, South Korea reported some surprising results. Within a month of recovery, around two percent of those infected tested positive for the virus for the second time! These disappointed survivors had to return to quarantine. And their families were monitored for fourteen days.
Then. . . another SURPRISE! None of the families got sick again!
Wait…? So can we go out or not?
It depends… on whether it’s a “Reactivation”... or “Reinfection.”
In a “reactivation,” hidden and inactive, remnants of the virus mount a second offensive! But no worries! Our body has special forces, called Antibodies!
Antibodies are proteins, which are building blocks of our body, produced in our blood. Their superpower to “neutralize” makes the attacking virus inactive. How? By looking at the antigen, the shape of the virus, antibodies bind with the virus. Our antibodies already know these antigens. Chance of winning: good. Infecting others? No.
In the case of a “reinfection” though, things are different. The virus army attacking us are new forces from outside. Reinfection is impossible if we still had the antibodies. But, the body stopped producing the antibodies, because it thought the battle was over. We’re no longer immune! Chance of winning? Unknown. Infecting others? Probably!
What about their families? Despite being very close to each other, none of them caught Covid for the second time! YAY! But WHY?
It could be a virus reactivation, rather than a reinfection. Still confused? Let’s look at a well-known example of virus reactivation: chickenpox.
We’ve all heard of YOCO, “You only get chickenpox once”. But the virus causing chickenpox can reactivate, and cause shingles. Shingles and chickenpox have different symptoms, and importantly shingles are not contagious. Why? Reactivation is possible, but reinfection? Impossible!
Let’s be careful though. There are many unanswered questions about Covid.
You want to go back to work, but don’t have the antibody army? Well, how about BTS ARMY instead?

Mosquitoes… they do more than ruin a nice day by the river. These winged brutes cause dozens of diseases from West Nile virus to malaria. During WWII, President Roosevelt had enough. He formed a special task force to rid the nation of this infectious threat… the CDC.
Armed with insecticide sprayers, they sprayed hundreds of military bases—and later, millions of households!—throughout the southeastern United States. The CDC has expanded (and of course, iterated through many name changes) to study and prevent the world’s most deadly diseases. Now, we don’t just rely on them to swat mosquitoes, we depend on them to lead us through global pandemics.

Smallpox… the word sounds harmless enough, but this “speckled monster” was the scourge of Western Europe throughout the 1700s. Why did it disappear? The credit belongs to a fiery 18th-century feminist.
Lady Mary Wortley Montagu rebelled against everything—her father, societal norms, and smallpox. After catching—and recovering from—the disease, she vowed to protect her children from living the same horror. But she had to face intercontinental travel, a pus-based economy, and a stubborn kingdom to do it. If she succeeded, Western Europe could be rid of smallpox forever.

Scientists in the media often have uncertainties around talking about experimental uncertainties. Why? Because they worry about trust! Error and uncertainty has a specific meaning in science. It gives us hard numbers on how much we can trust a measurement. But, the unfamiliar may believe it means mistakes and incompetence. In order to avoid any loss in public trust in science itself, scientists may not always talk about it. Are these fears grounded in reality? An important new study on uncertainty and trust certainly sheds light on the topic.

Have you been having weird dreams lately? If so, you’re not alone. Stressful, memorable, and intense dreams are on the rise! The stress of the pandemic might be to blame. This isn’t the first time a stressful event has changed the way that we dream.

The coronavirus pandemic has forced many people to work remotely. For human beings this time has been rather stressful, but what’s it like from Mother Earth’s perspective? With reduced human activity, skies have cleared up and pollution has gone down. Things seem to be going smoothly for the planet! But will this last? Well, we have seen something similar during the 2007 Great Recession of the United States. Carbon emissions plummeted because people weren’t consuming as much goods. However, when the economy started growing, there was a peak in carbon emissions. History has a tendency to repeat itself. Today, we can expect to see a similar trend when the economy reopens and people return to their jobs. Armed with this knowledge, we can make conscientious, sustainable decisions for our collective futures. Written and reported by Bahareh Sorouri.

What’s in a name? For humans, our identity. Same for viruses. Throughout history, viruses have cycled through names that have tried to identify them. Although labelling them by their location or origin seems like a good idea, hindsight has revealed negative side effects of this decision. Recently, the World Health Organization has recommended not including places, animals, and people when choosing a new virus name. This has led to clunkers like “SARS-Cov-2,” but will hopefully safeguard against racism and xenophobia down the line.

The coronavirus pandemic was caused by a virus that originated in other animals. If this virus can jump species, what’s to stop it from attacking our pets? Science from previous coronavirus outbreaks like SARS suggest that cats are susceptible! Now, a full grown tiger at the Bronx zoo has gotten sick with the new coronavirus. Luckily, science is on the case. Coronavirus can infect cats but doesn’t seem to affect dogs. Luckily, cats don’t show symptoms and there’s no evidence for widespread infections or cat-to-human transmission. We can all sleep soundly tonight - if Max would just move over, already!

Copper’s self-disinfecting properties are well known and well studied. Bacteria, viruses, doesn’t matter - they won’t survive long on a copper surface. In fact, research suggests that coating commonly touched surfaces with copper is an excellent method to prevent the spread of disease!

During times of uncertainty, reasonable decision-making flies right out the window. Consumers worldwide hoard items -- enough to last years! Even our ancestors had similar survival tactics. Survivors of England’s bubonic plague in the 1600s may not have built 2-ply fortresses. But, they did stockpile what they could find (hello, beer!). But WHY?
Psychologists believe it has something to do with our evolution. We’ve survived millenia by cooperating as a group. Our social skills have gotten us this far. If we see our “tribe” hoarding, we want to hoard too! Although we could fend off large predators with this impressive collaboration, our stores also run out of T-P!Written and reported by Brenna Biggs.
Viruses are insidious agents that invade human tissue, injecting their genetic instructions into our cells. Their goal? To make more viruses! Luckily, our body launches a full scale counter-attack. The foot-soldiers in this micro-war are antibodies. Our immune system creates new antibodies designed to bind to the shell of the virus, neutralizing it. When the battle comes to an end, we keep the antibodies around, and are thus immune to the virus. Science provides a pacifist's solution in the form of a vaccine. Vaccines can teach our bodies to defend themselves, but without all the fever and coughing. New viruses like SARS-CoV-2 have the element of surprise; we, the antibody-less herd, can do little to defend ourselves. However, as more of us become immune, the virus has a harder and harder time finding the vulnerable amongst the herd. How will we reach herd immunity - recovery, or vaccine? That depends on how long we keep our herd at home!Written and reported by Sumner L. Norman, Ph.D.
Masks: Spiderman, Jim Carrey, and the Phantom of the Opera all donned one. Our beloved face masks began as humble handkerchiefs as early as the 1600s. These evolved into surgical masks and -- eventually -- the heavily sought-after N-95 respirator!Masks are not just for villains and superheroes. We have long depended on them for protection. How did improving technoloy create the masks we know today? How can they protect against disease?Written and reported by Brenna Biggs.References:
Gamers unite! You can join forces with some of the best minds in research as they try to find a cure to the new coronavirus. Folding@home lets researchers borrow the processing power of your computer, allowing them to run simulations to figure out the structure of proteins within coronavirus. Their goal? A “cryptic binding site” that will hopefully be the key to shutthing this virus down.For more information, click here.

It's 2020 and students worldwide have been dismissed from their dormitories and classrooms. Zoom classes aside, many are wondering if there is any hope in salvaging this critical time in their lives. Many may be surprised to find, they're not the first students sent home on account of a pandemic! In 1665, the bubonic plague was ravaging much of England. As a result, one “Isaac Newton” was forced off the Cambridge University campus and returned home to shelter in place. In his newfound solitude, he came to develop the underpinnings of the theories of gravity & calculus… but Newton didn’t have Netflix! In these dire times, how can we mere mortals stay safe and sane?!Written and performed by Sumner L. Norman, Ph.D.
Plague, influenza, coronavirus... pandemics throughout history reveal successful viruses built for destruction. Mystery often surrounds the origins of these baddies. How did they come to be? Are dangerous viruses usually created in a lab, or is nature the real mad scientist? Learn how scientists can tell whether newsworthy nasties (like viruses and bacteria) are natural, or D-I-Y'd by humans! Hint: tracking the genetic family tree of the most infamous examples reveals the answer.Written and reported by Brenna Biggs.
Washing hands with soap and water for 20 seconds is cited as the best practice to protect ourselves from coronavirus. As impossible as it seems, something as mundane as soap really is out best defense again the new coronavirus. In fact, soap has a long history of keeping us safe. The answer lies in soap's unique chemical makeup, which is perfectly equipped for destroying viruses!Written and reported by Kellen Kartub, Ph.D.
"The Roaring 20s" (aka: the 1920's) was a time of unprecedented American innovation and prosperity. An explosion of Model T's on the road; cool new inventions from television to sunglasses and, yes, sliced bread. But in fact, America had just emerged from not just World War 1 but its own pandemic, the Spanish Flu. Wars, terrible as they are, galvanize societies to jumpstart technologies. WW2 bought us radar, GPS tracking, even microwaved popcorn. A pandemic such as coronavirus is like a war, with health workers on the front lines - what unexpected discoveries may come?!
