Research: Astronauts' gut health

The so-called "gut-brain axis" is the well-established bidirectional interaction between the gut microbiome and the brain. In other words, the microbiome in our gut has been found to influence many aspects of our brain: stress physiology and psychology, mood, cognition, and behavior.

A novel challenge has arisen from this finding. Namely, how can astronauts stay alert and healthy through their travels? 

One issue is the inadequate intake of micronutrients, which is generally associated with increased inflammation and stress. It also leads to reduced functioning of the immune system. Although the space travelers’ diet is not yet optimized, considerable progress has been made. For instance, the average caloric intake has been significantly increased in recent years.

However, it remains a fact that during spaceflights, astronauts eat less and generally more poorly than on Earth. Several possible reasons include cultural habits, the palatability of food, space motion sickness, changes in light-dark cycle and appetite-regulating hormones.

Optimizing the gut's microbiome is hard enough on earth. Doing so in space requires much more research. But the physiological and cognitive benefits for a healthy gut mean that astronauts will be more effective when they are in optimal health.

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?

That means Phase 3 typically involves many thousands of people and can take a significant amount of time. 

Chinese vaccines are being tested currently in Phase 3 clinical trials in several countries around the world, but are still facing the hurdles of data accuracy and patient recruitment. Some have suggested rushing through Phase 3, but this has drawn criticism from the WHO. “This Phase 3 must take longer because we need to see how truly protective the vaccine is and we also need to see how safe it is,” WHO spokeswoman Margaret Harris said during a media conference.

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.

Future studies could help treat malaria, in which the pathogens specifically infect human red blood cells through a mosquito bite. If scientists can make a mouse with even more human red blood cells, it would be a very good model to study malaria. They could also explore whether this technique could be applied to larger animals, such as pigs, to generate organs for transplants.

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.

The real problem is, they have no critical thinking skills. They believe whatever they hear as long as it fits with what they already believe. They'll say, 'Yes! That's the truth!'  Even if it's totally wrong. They don't stop to think about who's saying it or why. They don't stop to think. Period.

That's why the world is in so much trouble. That's why people refuse to believe the medical scientists and refuse to wear masks. And that's why the U.S. has the highest coronavirus infection rates of any developed country. It infuriates me that we are all put at risk because people don't know how, or won't, think."

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.

Supporters of female figures say that it's important to recognize women's right to be out in public spaces, given the long history of expectations that they stay at home. Australia and India have gotten on board. Geneva, Switzerland is one of several cities that has taken it even further by including pregnant women, old men and women, and same-sex couples.

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.

But now Amabié has returned, so to speak. People around the world are drawing it so much that it's become the unofficial COVID-19 mascot. It's represented in all sorts of styles, from cute cartoons to sexy superheroes. Check out #amabie on Instagram and #amabiechallenge on Facebook and Twitter to see Amabié around the world. And post your own version—who knows, it might help us overcome the coronavirus!

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.

The bus also had some extra luxury services like a reading and dining room on the lower deck, individual sleeping bunks, fan heaters to keep passengers warm, and aesthetic interiors to make the bus feel like home while on the long journey.

Albert the bus made more than 150 border crossings without ever being held up for searches or bribes at state borders. It earned the tag of being a "friendly ambassador" to all countries it visited along the way.

Take a look at the real Albert the bus here

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.

On top of this, window masks are also very helpful to people with diminished hearing, typically older people or grandparents, who rely on face-to-face interaction to understand

SIM-jacking and scamming

Technology has been quite a godsend for fraudsters. In the past, if you wanted to recreate a valuable painting you needed to painstakingly paint it, or if you wanted to open a fraudulent bank account, you had to physically grow a moustache to fool a bank teller. But these days, it's much easier. To beat two-factor authentication, scammers can simply transfer your phone number to a new SIM card and gain access to every penny you own.

This comparatively new crime is called "SIM-jacking". It works like this: perpetrators obtain important details about their victims either by searching social media or conning them into revealing personal information. Using these details, they pretend to be their victims, convincing network providers to transfer their phone numbers to new SIM cards and post out those SIMs. Once the switch is complete, messages containing codes for the two-factor authentication systems many of us now have can be intercepted, and fraudsters can log in to your email, social media or mobile banking accounts.

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.

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.

Big grocers like Walmart have been experimenting with new ways to fulfill online orders in the past few years. However, analysts say that consumers adopting online grocery shopping may add to the pressure small and mid-sized grocers already face, since they don't have as much capital to invest in building an online delivery infrastructure.

Where does consciousness come from?

According to BigThink, a publication focused on education, what consciousness is and where it comes from has absorbed great minds for thousands of years. In today's world, it's a question posed by physicists, cognitive scientists, and neuroscientists. There are a few prevailing theories.

The first is known as materialism. This is the idea that consciousness emanates from matter. In the case of people, by the firing of neurons inside the brain. If you take the brain out of the equation, then consciousness doesn't exist at all.

The second theory is mind-body dualism. This is perhaps more often recognized in religion. Here, consciousness is separate from matter. It is a part of another aspect of the individual, which in religious terms we might call the soul.

The third option, which is gaining ground in some scientific circles, is called panpsychism. In this view, everything material, however small, has an element of individual consciousness. A handful of scientists are starting to embrace this theory. Aspects of Shinto, Buddhist and Hindu religions also support panpsychism. But, it's still a matter of great debate.

In popular culture, Marie Kondo embraces a kind of panpsychism. For instance when faced with a pile of old books, she will take each one and slap it to "wake it up."

An explosion of stellar proportion

Global News, a Canadian news outlet, reported that astronomers detected an explosion over fifteen times the size of our galaxy. This makes it the biggest blast ever recorded.

The massive explosion occurred hundreds of millions of light-years away, where a supermassive black hole emitted large amounts of energy and matter while devouring a galaxy, blowing a hole in space that’s 2.58 million light-years across. It wiped out trillions of stars and tore through the surrounding galaxies. Researchers spotted the hole from the colossal gap it left in the middle of a cluster of galaxies.

The blast occurred in the Ophiucus cluster, a collection of galaxies some 390 million light-years away. It’s unclear exactly when the explosion happened, but researchers say it was definitely millions of years ago.

Rare giraffes come under threat

According to National Geographic, the remains of two white giraffes were found in a nature conservancy in northeastern Kenya. The giraffes likely had a rare genetic condition called leucism, which inhibits skin cells from producing pigment. It is believed that they were killed by poachers.

The animals had been well-known since 2017, after rangers spotted them in the conservancy and posted a video to YouTube, which then went viral.

This highlights a modern-day paradox: social media allows people to experience the joy and wonder of the planet’s rarest creatures while simultaneously putting animals at increased risk. Rarity and exclusivity are among the driving factors of the illegal wildlife trade, so unusual animals are more likely to be targeted by poachers.

National Geographic concluded that navigating how to report on unique animals without helping to put a target on their backs is a delicate process.

Bans on cashless stores

The cashless economy has become increasingly prevalent in developed countries such as the U.S. and Japan. Consumers are incentivized to use debit or credit cards through discounts and freebies, and banks and credit card companies collect information on people’s spending habits.

Some stores in the U.S. have decided to stop accepting cash from customers altogether, which has resulted in a backlash. Millions of people, most of whom live below the poverty line, do not have a bank account and only deal in cash. Advocates have argued that the cashless economy discriminates against poor people and the homeless.

American cities and states have started banning cashless stores on the grounds that they are discriminatory. San Francisco, New York City, Washington, D.C., Philadelphia and New Jersey have recently passed legislation forcing stores to accept all types of legal tender.

The Golden Age of Television

Over the past 20 years, American television entered a Golden Age. Before the turn of the millennium, most TV shows followed familiar patterns: crime shows and situational comedies—also known as sitcoms—consisted of self-contained episodes with little plot development through a season or the run of the show.

Then, in 1999, a network called HBO took a huge risk by investing $2 million per episode in The Sopranos, a show that broke with the familiar pattern of television productions. The Sopranos invested in character development and took its time to tell a compelling story. It was a massive success that showed that audiences were willing to sit through drawn-out shows as long as they were good. HBO reproduced that early success with Six Feet Under and The Wire.

As the years passed, other networks such as AMC and FX got on the bandwagon of high-quality, high-cost productions. The streaming giant Netflix then began producing binge-worthy television. With a per-episode cost of $15 million, the last season of Game of Thrones held the record as the most expensive ever produced. This was later dwarfed by Disney and Marvel TV spin-offs of movies, with a cost upwards of $25 million per episode.

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.

Renewable energy from wind, solar and hydro is projected to make up less than a quarter of total electricity by 2030, far below the global average. Roughly the same amount is projected to come from zero-emission nuclear sources, but only if the government turns on additional reactors. Even under optimistic scenarios for the next decade, more than half of electricity will come from coal, natural gas and other fossil fuels.

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.

Wildlife officers charged the zoo with one offence relating to the bear being taken for ice cream, and another for incidents where the bear left the facility on multiple occasions without the proper authorities being notified.

The rise of the hikikomori class

The Japan Times reports that the number of hikikomori in Japan, or those choosing complete withdrawal from all social interactions, has grown over the past few years. Psychiatrist Tamaki Saito, an expert on the subject, has stated that there might be some 2 million hikikomori in Japan, more than the official government estimate of 1.15 million. He also warned that the total number of Japanese foregoing social interactions might be as high as 10 million.

Official government estimates state that 613,000 hikikomori are between the ages of 40 and 64, raising the question of just how many elderly hikikomori will survive after their parents, who provide for all their daily needs, become ill or pass away.

Past studies argued that the main reason for the increase of hikikomori is related to a rigid social structure, which expects everyone to conform to certain socio-economic norms. Those who are unable to become productive members of society escape from all social interactions because of the amount of pressure placed on their shoulders. Additionally, some hikikomori may simply think that the benefits of partaking in real-life social interactions are not enough to compensate for all the personal stress. According to these studies, Japanese society should do more to help these individuals recover.
