Flip-flops made from algae

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. 

COVID vaccine: Phase 3's importance

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?

Harvesting human cells from animals

CNN reports that scientists have created a mouse embryo that's 4% human. The hybrid is what scientists call a human-animal chimera, a single organism that is made up of two different sets of cells. This human-mouse chimera has by far the highest number of human cells ever recorded in an animal.

The team's experiment indicates that there is enough evolutionary compatibility between mice and humans that mouse embryos are a relatively good environment for cultivating human cells. This breakthrough could potentially generate better mouse models to study human diseases, including Covid-19. Mice can also be used to grow human immune cells or respiratory cells.

Opinion: Critical thinking needed!

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.

Gender equality on traffic lights

The iconic "Sophie" pedestrian crossing signal (pictured above) first appeared outside City Hall in Amersfoot, the Netherlands, in December 2000. Since then, she has inspired female figures on crossing signals around the world. As Dutch Ambassador Wim Geerts said in 2013, "Sophie is much more than a traffic light, as she encourages us to think about women's rights." She also seems to improve pedestrian safety—more people stop for Sophie than for lights with common male figures.

Some people criticize "Sophie" and other female figures as promoting stereotypes of women. They always wear a skirt, and Sophie has ponytails which are commonly associated with little girls. Rather than add stereotypical images of women, these critics recommend creating a non-gendered stick figure.

A mascot for the pandemic

Mascots, or yuru-kyara, are incredibly popular in Japan. There are yuru-kyara for everything, from sports teams to prefectures to a toilet disinfectant (seriously). Now they're offering the world a mascot for the novel coronavirus pandemic.

The yōkai (supernatural being) Amabié was first described in 1846, during a series of severe epidemics in Japan. It has three legs, a fish-like body, and the head of a bird with long, flowing hair. The original story goes that Amabié was spotted by an unnamed man on top of the ocean waves, glowing with a strange light. It gave its name to the man and prophesied a good harvest. Then Amabié said, "Should an epidemic come, draw me and show me to those who fall ill and they will be cured,” and disappeared into the water, supposedly never to be seen again.

World's longest bus route

According to the India Times, in May 1968, a British traveler named Andy Stewart was looking to make his way home to London from Sydney, Australia. So he bought a double-decker bus and converted it into a mobile home, nicknamed "Albert". That October, he set off with 13 others on Albert the Bus for a 16,000-kilometre journey from Sydney to London via India. The journey took 132 days to complete.

Things turned out pretty well for Albert, considering it went on to complete 14 more Sydney-to-London trips over the next 8 years. A "year-round timetable" was drawn up for a regular service between London, Kolkata and Sydney in what was called Albert Tours.

Facial masks and deafness

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.

Nestle renames insensitive products

Classic Australian lollies Redskins and Chicos are set to be renamed so they don't marginalise consumers, confectionery company Allens has announced.

The decision was made by the brand's parent company, Nestlé, because a redskin is a slang term for Native Americans in the U.S., where it is considered offensive. Chico, which is Spanish for "boy", is also used in a derogatory way. 

"This decision acknowledges the need to ensure that nothing we do marginalises our friends, neighbours and colleagues," the company said in a statement. "These names have overtones which are out of step with Nestlé's values, which are rooted in respect."

The company has yet to announce new names for the popular treats.

Tech trends for the next 10 years

In a Forbes article, Bernard Marr predicts the 25 most important technology trends that will define the next 10 years. Not surprisingly, a number of them involve A.I. and IoT. Others will come from things like virtual, augmented and mixed realities; nanotechnologies; 3D printing; and Big Data.

The past 20 years have given us major technological game-changers, like Bluetooth, social media, and, of course, the iPhone. Other innovations include flash drives, hybrid cars, GPS, and the Cloud.

The speed of change in technology is increasing exponentially—every new development drives a number of others, each of which drives more, resulting in faster and faster change. It looks like this:

What technology trends do you think will drive the next 10 years?

Surge in online grocery shopping

According to CNN, the outbreak of the coronavirus is pushing many Americans to buy their groceries online. With shoppers stuck in their homes, downloads of Walmart's grocery app and Shipt increased by 160%, and 124%, respectively, in early March compared with the same period last year. Instacart more than tripled, increasing by 218%!

While shopping for books and electronics online, and ordering dinner through delivery apps, have become the norm in American life, before the coronavirus outbreak most customers still preferred to purchase their meat and vegetables at the store. Last year, only 4% of grocery sales in the United States were made online.

According to a survey by analysts at Gordon Haskett Research Advisor, a third of consumers said that they had purchased groceries for online pickup or delivery in March, 2020. Around 41% said they were buying groceries online for the first time.

Coal energy challenges in Japan

According to The Japan Times, the tragic events of March 11, 2011, when a massive earthquake and tsunami triggered meltdowns at three nuclear reactors in Fukushima, forced Japan to reconsider nuclear energy. Today, 24 of Japan’s 33 reactors remain offline.

After the disaster, the government increased its push toward renewable energy, but it also invested heavily in coal projects. The dirty fuel was seen as the fastest, cheapest and most reliable way to keep the lights on.

A return to coal has left Japan with only modest long-term climate goals. Electricity generation is now responsible for almost 40 percent of the country’s emissions, and Japan aims to cut total emissions 26 percent by 2030 from 2013 levels.

A bear at an ice cream shop

The Canadian Broadcasting Corporation reported in 2018 that a private zoo in Alberta, Canada, was charged after a bear from the facility was taken through a Dairy Queen drive-thru in a pickup truck and fed ice cream through the vehicle's window.

A video of the feeding was posted to Twitter and Facebook by Discovery Wildlife Park, but the posts were later deleted. It showed a one-year-old chained bear leaning out of a truck's window and being fed ice cream by the owner of the local Dairy Queen. Another video posted by the zoo around the same time showed the bear licking frosting off an ice cream cake.

A trainer at Discovery Wildlife Park said there was no safety concern at the Dairy Queen because the bear was on a chain in the truck the entire time.

Consultancy will survive COVID-19

The novel coronavirus COVID-19 has impacted the consulting industry in ways that seem potentially ruinous. But do not lose hope. Yes, consultants are used to traveling a lot, and widespread travel restrictions make that impossible. And much of consultancy work is done face-to-face in internal and client meetings, which can’t be done when gatherings are prohibited. There is also the fear that businesses will suspend contracts in the economic downturn.

But we have an advantage this time that we haven't had in past catastrophes. We have the internet. We can have virtual meetings, share documents online and even give presentations with conference software that lets everyone be in the same “room” at the same time. So travel restrictions are less disruptive than in the past—people can do much of what’s needed almost as well from home.

COVID-19 overloads the internet

Many businesses are asking their employees to work from home to help stop the spread of COVID-19.  Suddenly workers need to use telecommuting networks all day long. It’s putting a huge demand on internet services. 

Also, many schools have been closed. So children are home doing classwork online and watching videos or playing games. In Italy, internet usage went up by 90% in March when schools were closed. 

So home network providers are being tested in a way they never have before. Large providers say they can handle it, but no one knows when this situation will end. Hopefully the internet will keep working until then.

COVID-19: A global economic crisis

This simple equation is at the heart of the global economy: One person’s spending = another person’s income.

It’s referred to as “supply and demand”—producers will supply as much as consumers demand. So if consumers aren’t buying anything, producers won’t be able to sell anything. In other words, whenever you buy something, you pay someone else’s wages.

So the current COVID-19 pandemic is not just a global health crisis but also an economic one. When people are told to stay at home, they stop going to restaurants, bars, and movies. They can’t travel, so they don’t spend money on gas or airfare, and they don’t stay at hotels. And when no more than 10 people can be together in one place, everything from birthday parties to music festivals to major world sports events are canceled.

Cashing in on the Olympics

In 2017, the Tokyo Metropolitan Government estimated that the economic effects of the upcoming Olympic Games will be worth about $292 billion over a span of 17 years. In an attempt to cash in on this, a wide array of businesses in Japan have been ramping up preparations, including the taxi industry.

In January 2018, the Japan Federation of Hire-Taxi Associations formulated measures for the Olympics and Paralympics. The association set a goal of having 9,000 drivers taking English lessons by April, and over 16,000 have already completed them.

Only drivers who have completed at least a mid-level English course are allowed to pick up passengers at the international terminal at Haneda airport in Tokyo. To take the exam, which is designed to test communication skills, drivers must finish an advanced English course.

The gig economy and labor rights

According to the Israeli newspaper Haaretz, a report studying freelancers published by consulting firm Mackenzie said that the gig economy has done away with workers’ rights achieved through decades of activism and legislation. Mackenzie concluded that freelancers face labor conditions similar to those of workers before the Industrial Revolution.

The advantage for employers is clear, as working with freelancers offers companies managerial flexibility. They pay for the services of a person as if that person were an entire company, without any obligation to provide social benefits or fulfill labor laws. It turns the employer–employee relationship into a customer–supplier one, which can be very unequal.

A report by the Upwork and Freelancers Union forecasts that by 2027, some 50% of all U.S. workers will be freelancers. Mackenzie estimates that the current proportion is around 20-30%, which includes people who supplement their income through freelance work.

Antivirus company selling your data

An antivirus program has been found to have been selling users' data to a wide variety of companies. A subsidiary of the Avast antivirus group, a popular and well-reviewed line of antivirus software, has been selling every purchase, every page, even every click that users have made. Clients have included tech companies, consulting companies, a soft drink company and even a large hardware store. 

The program is called Jumpshot, and it is able to supply clients with a so-called "All Clicks Feed." That option tracks every click and all time spent across websites in highly precise detail.

Avast has since made the information-sharing aspect optional, though the company has said that the information gathered before the change will be kept rather than deleted. 

It has been said that users should be skeptical of free programs. There is an adage on the Internet that if you aren't paying for the product, then you are the product

Universal phone charging ports

Electronic waste is a huge problem. There's an estimated 51,000 tonnes of it globally per year, says the European Union. But a new law could put an end to one part of it.

The E.U. has passed a law that as of 2024, all phones will have a standard USB-C charger. Having a single type of smartphone charging port will make cables interchangeable and more reusable. This standard charger would also improve the customer experience. 

Maybe you've been using your phone when the battery runs low, and your friend offers you a charger, but it's the wrong kind. Many of us have had our phone die while we are out and about, far from our charger. A standard charger would solve this problem.
