Researchers say spicy tomatoes could soon be on the menu thanks to the rise of gene-editing technology.
It's not the first time that experts have claimed techniques could develop fruit with unusual features: scientists have already been looking at changing the color1 of kiwi fruit and bettering the taste of strawberries.
But researchers inBrazilandIrelandsay such methods could also offer practical advantages, with hot tomatoes offering a new way of harvesting the pungent chemicals found in peppers known as capsaicinoids, which make food taste “hot”.
“Capsaicinoids are valuable. They are used as painkillers and there are some researches showing that they promote weight loss,” said Agustin Zsogon from a Brazilian university, a co-author of a new article arguing for the benefits of engineering hot tomatoes.
Writing in the journal Trends in Plant Science, the researchers say peppers are difficult crops to grow and low productive. Worse still, it is tricky to keep the pungency of the fruits table. By contrast, tomato production is high and the plant is well-studied. “You could produce the capsaicinoids in a more cost-effective manner,” said Zsogon.
Tomatoes and peppers developed from a common ancestor, but separated about 19 million years ago. “All these genes to produce capsaicinoids exist in the tomato, they are just not active,” said Zsogon. “Using gene-editing technology, it is likely to switch these genes back on in tomatoes, making the fruit more special”, he said.
4. Why are the tomatoes made hot by the researchers?
A. To test the gene-editing technology
B. To improve the amount of the tomatoes
C. To explore ways to harvest more capsaicinoids.
D. To make the tomatoes more delicious.
5. For what purpose can capsaicinoids be used according to the text?
A. To put on weight.
B. To ease the pain.
C. To improve sleep.
D. To better the look.
6. What is Zsogon's attitude to the gene-editing technology?
A. Confident.
B. Critical.
C. Anxious.
D. Doubtful.
7. What's the main idea of the text?
A. An introduction to gene-editing plants.
B. Creating hot tomatoes by gene-editing.
C. Problems with capsaicinoid production.
D. The procedure of producing capsaicinoids.
C
NASA has flown an aircraft on another planet for the first time. On Monday, April 19, Ingenuity, a 1. 8-kilogram drone (无人机) helicopter, took off from the surface of Mars, flew up about threemeters, then hovered for 40 seconds and took photos above with one of its two cameras. The historic moment was livestreamed on
YouTube. “We can now say that human beings have flown a drone helicopter on another planet,” said MiMi Aung, the Ingenuity Mars Helicopter project manager at NASA's Jet Propulsion Laboratory, at a press conference. “We, together, flew at Mars, and we, together, now have our Wright brothers moment,” she added, referring to the first powered airplane flight on Earth in 1903.
The details: The flight was a significant technical challenge, thanks to Mars' s bone-chilling temperatures (nights can drop down to -130 °F / -90 °C) and its incredibly thin atmosphere — just 1% the density of Earth' s. That meant Ingenuity had to be light, with rotor blades (螺旋桨) that were bigger and faster than would be needed to achieve liftoff on Earth (although the gravity on Mars, which is only about one-third of Earth's, worked in its favor). The flight had originally been scheduled to take place on April 11 but was delayed by software issues.
Why it's significant: Beyond being a significantmilestonefor Mars exploration, the flight will also pave the way for engineers to think about new ways to explore other planets. Future drone helicopters could help astronauts by scoping out locations, exploring inaccessible areas, and capturing images. Ingenuity will also help inform the design of Dragonfly, a car-size drone that NASA is planning to send to Saturn's moon Titan in 2027.
What's next: In the next few weeks, Ingenuity will conduct four more flights, each lasting up to 90 seconds. Each one is designed to further push the limits of Ingenuity's capabilities. Ingenuity is only designed to last for 30 Martian days, and is expected to stop functioning around
May 4. Its final resting place will be in the Jezero Crater as NASA moves on to the main focus of its mission: Getting the Perseverance rover (毅力号火星探测器) to study Mars for evidence of life.
8. Why does MiMi Aung mention Wright brothers?
A. To honor the historic contribution of Wright brothers.
B. To make a comparison between Wright brothers and herself.
C. To highlight the importance of Ingenuity's Martian exploration.
D. To remind the public of the first powered airplane flight on Earth.
9. What caused challenges for Ingenuity designers?
A. The delay of software tests.
B. The force of gravity on Mars.
C. Mars's temperatures and atmosphere.
D. Technical difficulty in liftoff on Earth.
10. What does the underlined word “milestone” in Paragraph 3 probably mean?
A. A great victory.
B. A difficult task.
C. A roadside stone.
D. A historic event.
11. Which of the following can be a suitable title for the text?
A. Mars Drone Helicopter Makes Historic First Flight
B. Modern Wright Brothers Moment: Mars Exploration
C. First Drone Helicopter Spots Evidence of Life on Mars
D. Ingenuity: Mars Drone Flies to Take Incredible Pictures
D
Where doyou usually put your toothbrush?Do you keep it in the bathroom? How’s your toothbrush looking these days? Even if you can’t see it with a naked eye, experts say it may be saturated(使饱和)with millions of toilet germs!
Dr. Charles Oerba, a germ expert, is amicrobiology professor at the University of Arizona. He says there are approximately 3 million bacteria per square inch in most toilet bowls, and every time you flush it without closing the lid, those millions of bacteria droplets spray into the air as far as twenty feet away and dirty everything in their path. And a common victim is your poor toothbrush, usually, left out on the bathroom sink, right?
So, what do we do? Dr. Gerba says it’s easy. Close the toilet lid before you flush—that’ll greatly cut downthe germs, which will otherwise float in the air. And wash your toothbrush every few days in mouthwash or peroxide to get rid of any germs hiding in it. You can even put it through the dishwasher to sanitize(消毒)it. And always store your toothbrush in a closed cabinet.
Here’s one more tip from Dr. Gerba, who says our kitchen sink is probably dirtier than our toilet. “If an alien came from space and studied the bacterial counts, he probably would conclude he should wash his hands in your toilet and go to the bathroom in your sink.” He says that’s because the kitchen sink is a great place where E. coli(大肠杆菌)to live and grow since it’s wet and damp. Bacteria feed on the food that people put down the drain or—that’s left on dishes in the sink. To reset your sink’s bacteria count back to zero, you’d better regularly wash it with hot water and sanitize yoursink with special chemicals. In fact, you may want to do it every day or before preparing dinner.
12. What is the purpose of the text?
A. To show how to brush your teeth.
B. To tell people the importance of health.
C. To warn people of the invisible germs.
D. To introduce a microbiology professor.
13. What can we learn from Paragraph 2?
A. Bathroom sinks are the dirtiest places.
B. Bacteria are bad for people’s health.
C. Why bacteria spread through the air.
D. How bacteria spread in the bathroom.
14. What does the underlined word“that”in Paragraph 4 refer to?
A. The food.
B. The toothbrush.
C. The sink.
D. The chemical.
15. Why does Dr. Gerba mention the example of an alien?
A. To tell us a fiction story of an alien studying bacteria.
B. To show our kitchen sink may be dirtier than our toilet.
C. To teach us how to reset sink’s bacteria count back to zero.
D. To prove coli prefers to live in the kitchen and the drain.
