Human beings are flawed. So no system of defense that depends on human action is going to be able to protect us 100% of the time. But we can prevent most problems. In 1990, Professor James Reason came up with the "Swiss Cheese model" to create defenses that are hard to break through.

Rice straw, or wara, is the waste left over from rice production. It used to be used to make tatami mats, bags, and other daily goods, including shoes. But these days most things are made from plastic and other synthetic materials, so farmers are left with mountains of useless wara.
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.

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.
CNN reports that according to the International Air Transport Association (IATA), providing a single dose of a future coronavirus vaccine to all 7.8 billion people in the world will require the use of 8,000 Boeing 747 cargo aircraft, and that planning needs to begin now.
IATA's director general and CEO, Alexandre de Juniac, said in a public statement that "safely delivering Covid-19 vaccines will be the mission of the century for the global air cargo industry."
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.

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.
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?
Currently, 34 vaccine candidates for the novel coronavirus are in various stages of clinical development, according to the World Health Organization (WHO).

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

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.

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.
