Answer these questions.

Teacher: Alright, can you guess the thing that I'm going to tell you about?
Student 1: What is it, ma'am?
Teacher: It is a kitchen appliance.
Student 2: What's it like, ma'am?
Teacher: This appliance consists of a removable bowl. Beneath is a heater and a thermostat. A spring pushes the thermostat against the bottom of the bowl for good thermal contact. During cooking, it is heated at full power. By the end of cooking, there will be no free water left.
Student 1: I think I know what you mean. It's a rice cooker. It's used for cooking rice.
Teacher: Yes, you're right.
Student 2: But nowadays, a rice cooker is not only used for cooking rice, ma'am.
Teacher: That's true. Dishes can be made in a rice cooker, including beef stew. By simply adding ingredients and setting it to "warm", a rice cooker cooks that at about 65°C. In a few hours, the stew is fully cooked and ready to eat.

Could Synthetic Fish be a Better Catch of the Day?
Overfishing has depleted numbers of wild fish, and fish farms meet much of the growing demand. Could we one day be eating "fish" grown from cells in a factory, as a number of start-ups are planning? Business is booming says David Shenson, the President of Sterling Caviar, which owns four fish farms in Sacramento, California, raising sturgeon for their eggs, better known as caviar.
He's not just being self-promotional: The global caviar market reached £670m ($854m) in 2018 and is expected to expand by close to 10% by 2025, according to market research firm Androit Market. Sturgeon is one of the fish that has come under pressure in the wild, the number of wild sturgeon in major river basins has declined by 70% over the last century, according to figures from the World Wildlife Fund. Overfishing and global warming have long wreaked havoc on fish stocks, and a third of marine fish stocks are still being fished at biologically unsustainable levels, according to the UN.
Fish farms, like Sterling Caviar, are helping take the pressure off wild stocks, but a handful of start-up firms think they might have another answer.
They are experimenting with growing fish "meat" in the lab.
Mainly based in Silicon Valley with a couple in Europe and Asia, they have developed techniques to extract fish stem cells and grow them into commercial quantities of edible flesh.
Stem cells are a type of cell found in embryos or adult creatures - which can grow into a number of different specialized cells. They can grow into the muscle cells which make up most the parts of fish people like to eat.
"Picture it like 3D printing, but we're 3D printing fish," explains Michael Selden, chief executive, and co-founder of lab-grown fish start-up Finless Foods.

A Canadian Tourist Has Died After Falling from a Popular Zipline Attraction in Northern Thailand
Local media reports say a Canadian man has died after the cable of a zip line he was traveling on snapped in Chiang Mai, northern Thailand-the latest accident to befall the popular Flight of the Gibbon tourist attraction.
According to the Bangkok Post, the man was identified as 25-year-old. Spencer Charles, who was vacationing in Thailand.
Local officials in Mae-on district told the Post that the accident happened late on Saturday morning when a cable was reportedly disconnected shortly after Charles was released from the start of the zip line, causing him to fall more than 300 feet to the creek below.
The year before, an American woman and a Chinese woman, crashed into each other while riding the zip line and were hospitalized.
According to a Post report of 2017, the husband of the Chinese woman claimed in a statement to a Thai court that there was no first aid kit available on the site at the time of the accident, while the American woman suffered from brain trauma and lost vision in one eye as a result.
The Flight of the Gibbon bills itself as "a chance to encounter wild gibbons in their natural habitat" by ziplining through "the ancient Thai rainforest." It says it has "the highest international safety standards"; and "fully trained staff" it calls "Sky Rangers."
It was founded in 2007 by New Zealander David Allardice, according to its website, and operates zip line attractions in Chiang Mai and in the Thai capital Bangkok.
The company has accepted full responsibility for the accident, said an official cited by the Post, and an investigation is underway.

Dr. William Frankland, one of the top allergists of the 20th century and an indomitable researcher who helped legions of hay fever sneezers by distributing daily pollen counts to the British public, died on Thursday in London at 108.
His son, Andrew, said the cause was the coronavirus. He lived in a care home at the historic Charterhouse complex, a former monastery in London.
Dr. Frankland, who was among the world's oldest active scientists, remained remarkably vigorous to the end, despite having come close to death several times in his long life; He was born prematurely weighing just over three pounds, and he contracted bovine tuberculosis as a child Later, while serving in the British Army, he spent years as a malnourished prisoner of war in Japanese camps. He had another brush with death when he used himself as an experiment on a biting insect and had an anaphylaxis reaction.
Dr. Frankland was best known in professional circles for a number of groundbreaking clinical studies. In 1954, he proved that pollen proteins were the parts of plants most useful in preseason allergy inoculations, and in 1955 he debunked the efficacy of treating asthma with bacterial vaccines.
He was an early proponent of using allergen injections to desensitize patients with severe allergies, and developed immunotherapy serums for hay fever sufferers with pollen from one of the world's largest pollen farms, which he operated outside London until the late 1960s.
