Health & Fitness Weird gadget may cure hiccups, early study suggests

A number of new words and phrases entered the general lexicon in 2020. We were told we need to "social distance," or stay six feet apart, so that we could "flatten the curve," or slow the disease's spread in order to reduce the burden on the healthcare system. People even became familiar with relatively obscure epidemiological terms like the "basic reproduction number" (R0, pronounced R-nought), or the average number of people who catch the virus from a single infected person. And of course the name of the illness itself, COVID-19, is a new term, with the World Health Organization officially naming the disease on Feb. 11 2020.

The must-have fashion item of 2020 was a small piece of cloth to put around your face.

With medical masks in short supply at the beginning of the year, sewing enthusiasts began churning out homemade masks for their communities. Then, clothing companies and retailers got on board, adding masks to their fashion lines. Now, in many parts of the world, you can't leave your house without putting on a mask.

What is Darwin's Theory of Evolution?

Charles Darwin's theory of evolution and natural selection isn't an idea with holes. It's one of the most solid theories in science. But what exactly is it?Darwin chose the term "natural selection" to be in contrast with "artificial selection," in which animal breeders select for particular traits that they deem desirable, according to National Geographic. In natural selection, it's the natural environment, rather than a human being, that does the selecting.

At first, it was unclear whether wearing cloth masks would protect against COVID-19, but as the year went on, numerous studies showed the benefits of wearing masks, for both the wearer and those around them.

The pandemic took a serious toll on people's mental health in 2020. One study published in August by the Centers for Disease Control and Prevention (CDC) found that levels of anxiety, depression and suicidal thoughts skyrocketed amid the pandemic.

The study could not determine the reason for the rise in mental health conditions, but factors relating to the pandemic, such as social isolation, school and university closures, unemployment and other financial worries, as well as the threat of the disease itself, may play a role, the authors said.

As businesses began to open after initial lockdowns, people needed to adjust to a new normal to reduce the risk of spreading the disease from everyday activities. Businesses implemented universal mask policies. Dining switched to outdoors only. Waiting rooms became a thing of the past. You needed a reservation to go to the gym. And large gatherings and events were banned completely in many areas.

Although there is no way to ensure zero risk of catching COVID-19, officials said taking precautions could reduce the risk of spread. However, as the fall began, many areas went into lockdown again amid surging COVID-19 cases.

From the idea that drinking bleach can kill the norovirus to a theory that the virus was created in a lab as a bioweapon, the COVID-19 pandemic has generated a flurry of misinformation. Indeed, one study, published Aug. 10 in the American Journal of Tropical Medicine and Hygiene, found that the pandemic has hatched more than 2,000 rumors, conspiracy theories and reports of discrimination.

Such false information can have serious consequences — the researchers of the new study found that COVID-19 related rumors were linked to thousands of hospitalizations and hundreds of deaths.

"Health agencies must track misinformation associated with ... COVID-19 in real time, and engage local communities and government stakeholders to debunk misinformation," the authors concluded.

Sorry to Break It to You, but Lavender Might Not Be the Magic Acne Cure After All

In the beauty industry, you'll find lavender pretty much everywhere. It's blended into bath salts to help alleviate our aching muscles, mixed into calming facial mists to soothe our skin, used as an aromatherapy oil to potentially keep stress at bay, and added to fragrances to help bring back memories of our grandmother's garden. Although the plant has been used for thousands of years, more recently, it's getting a lot of attention for its apparent abilities to help reduce breakouts.

With orders to stay at home as much as possible, many people decided to get a furry friend during quarantine.

The coronavirus pandemic has been a boon for pet adoptions, particularly dog adoptions. Many shelters, breeders and pet stores reported a surge in applications for dogs, with the demand far exceeding supply, according to The Washington Post. Some shelters reported double the number of adoptions compared with the previous year, and needed to resort to waitlists to handle the demand.

Not only is this good news for pets who need homes, but also for their humans, given that many studies show there are mental health benefits to pet ownership, according to NPR.

Children seem to be largely spared from the most severe effects of COVID-19, but they can still act as spreaders of the disease. So many schools across the U.S. and the world made the decision to close in 2020, and opt for virtual learning instead. Questions around how long to remain closed and how to safely reopen were the subject of much debate. As fall arrived with a number of schools still closed, many children seemed to be falling behind in learning. Statewide polls have found that nearly 9 in 10 parents are worried about their children falling behind at school due to the pandemic closures, according to The Educational Trust.

Coronavirus lockdowns, which slowed the normal hustle and bustle of cities to a near halt, also appeared to dramatically lower emissions of carbon dioxide around the world. A study published May 19 in the journal Nature Climate Change found that daily global carbon dioxide emissions dropped by 17% in early 2020, compared with levels in 2019. That appears to be one of the biggest drops in recorded history. But this temporary drop is far from enough to undo the harmful effects of man-made climate change.

"Although this is likely to lead to the largest cut in emissions since World War II, it will make barely a dent in the ongoing build-up of carbon dioxide in the atmosphere," Richard Betts, Head of Climate Impacts Research at the Met Office Hadley Centre in England, said in a statement.
