An interesting situation has emerged in the American stock market. It has caused the stock of several companies to be extremely volatile.

Hedge funds in the US have opened so many short positions—basically, they have bet that stock prices will fall. Now it is believed that they have short sold more than the number of shares available on the market.

However, savvy retail traders noticed this. They started to buy up these shares in large volumes in the hope to push up the price.

Trading has been so aggressive that the share prices have wildly fluctuated and multiple brokers have been refusing to even allow purchases. The situation has gotten lots of attention, with multiple members of congress showing interest in the behaviors of brokers and hedge funds. Some have called for congressional inquiries.

It isn't clear what the aftermath will be. Only time will tell.

According to The Guardian, a newspaper based in the United Kingdom, Bookshop is a socially conscious alternative to Amazon that allows readers to buy books online while supporting their local independent bookseller.

Bookshop was founded by writer and co-founder of Literary Hub, Andy Hunter. It allows independent bookshops to create their own virtual shopfront on the site, with the stores receiving the full profit from each sale. Customer service and shipping are handled by Bookshop and its distribution partners.

The COVID-19 pandemic forced most professionals around the world to begin working from home in early 2020. Suddenly teams were separated and had to communicate over video call services. It’s hard to feel connected that way. And it’s hard to build relationships and maintain the trust that today’s business depends on. 

Albert Einstein spent nearly a decade developing his theory of general relativity, which he published in 1916. The theory asserts that gravity is matter warping space-time and so gravitational bends in space can alter the passage of time. While an appealing theory, it is yet unproven.

According to CNN, the first image of a black hole, captured in 2019, has revealed more support for Einstein's theory. The new finding has suggested his theory is now 500 times harder to disprove.

The black hole in this study is 6.5 billion times more massive than our sun. The research team measured the distortion in the black hole’s gravitational pull and found that the size of this black hole's shadow aligns with the theory of relativity, or matter warping space-time to create gravity.

While the theory of relativity has passed all of the tests thrown at it over the past century, further study is needed to confirm whether it continues to match up with astrophysical objects.

The Guardian reports that more than a decade of police crackdowns on major gangs and economic uncertainty are making it harder for the yakuza to tempt young men with promises of easy money.

For the first time since records began in 2006, 51% of regular yakuza members are aged 50 or over, according to a new report by the national police agency. Less than 15% are under 40, and those over 70 account for just over 10% of total membership.

Stricter laws, including those targeting businesses with links to gangs that had once operated with near-impunity, have made a life of crime increasingly unappealing. Yakuza members are forbidden from opening bank accounts, obtaining a credit card, taking out insurance policies or even signing a contract for a mobile phone.

Algae is used in lots of ways, from food to health supplements to fuel. Now we can add flip-flops to the list. Flip-flops, commonly made from rubber, foam or plastic, are hugely popular all over the world. When people lose theirs on the beach, which happens frequently, the flip-flops are swept into the ocean to join the rest of the plastic pollutants collecting there. 

To solve this problem, new biodegradable "plastics" are being developed using something else found on the beach: algae. A chemistry professor at University of California, San Diego, Mike Burkart, is spearheading a project to make flip-flops out of algae so that, instead of creating pollution, they decompose naturally. Major shoe manufacturers are talking with Burkart about using his material, as are producers of food storage containers and other plastic items. 

Currently, 34 vaccine candidates for the novel coronavirus are in various stages of clinical development, according to the World Health Organization (WHO). However, the process is long, typically many years. In the race for a vaccine, there is some debate on the merits of rushing through the process.

The vaccines process is long because there are 3 phases of trials. The first two trials focus on effectiveness—does the vaccine work or not. This is a relatively straightforward question and it can be proven in relatively small sample sizes. So, just a few hundred people are needed to test it. However, Phase 3 is used to prove the safety and efficacy of the vaccine—does it have significant side-effects, is it safe for people with compromised immune systems, and can everyone use it?

This opinion is a rant—a passionate, typically angry, speech or piece of writing about one particular topic.

This rant is about American anti-maskers—people who are opposed to wearing a face mask during the coronavirus outbreak. 

Take a deep breath and try to read as emphatically as you can.

"I can't stand it! These people who won't wear masks even though all the medical science says it helps prevent the spread of COVID-19. I hope all the anti-maskers have never taken meds for anything, or know anyone who has. That includes blood pressure meds, insulin, asthma inhalers, allergy medicine, pain relievers, eye drops—heck, even bandaids! What do they put on a cut? Natural remedies like moss and honey? I highly doubt it. So they're either totally ignorant, or total hypocrites.

Around 48 million people have some degree of hearing loss. Given the rise of wearing face masks in public, hearing-impaired people are struggling to understand those wearing ordinary masks as they muffle their voices. One way to solve this problem is to put on masks with clear windows.

When wearing such a mask, people can see your lips, which allows the deaf or hard-of-hearing to lipread and see facial expressions.

Alicia Austin teaches infants and children who are deaf or hard-of-hearing. Currently, Austin has many online lessons with her students, and she says that wearing a mask can make communication problematic. She says that children need to see facial expressions and recognition to learn, even if they do not have a hearing disability.
