21、Blood donations save lives. But blood can only be stored under refrigeration for up to six weeks. After that, it’s no longer usable for transfusions. Because of that limitation, people have to continually donate blood to meet the needs.
Jonathan Kopechek, a bioengineer from University of Louisville says suspension to regular blood donations due to COVID-19 has put stress on the blood supply, and the pandemic underscores the need for more reliable long-term storage methods.
Good news is that Kopechek’s team has developed a method of preserving blood so it can be stored in a dehydrated(脱水的) state at room temperature. To do so, they turned to a sugar called trehalose(海藻糖), which is a common ingredient in donuts(甜甜圈). Trehalose is intended to help make them look fresh even when they are months old, and you wouldn’t know the difference.
The researchers chose trehalose because, in nature, it’s made by animals like sea monkeys—famous for their ability to survive dehydration. “So these animals can dry out completely for a long time and then be rehydrated and resume normal function. So we wanted to use the trehalose produced by these organisms and apply that to preserving blood cells in a dried state.”
But first, the researchers had to get trehalose into blood cells. To achieve this, they drilled temporary holes in the cell membranes(细胞膜). And they need to have sufficient trehalose on both the inside and the outside of the cell in order to survive the dehydration and rehydration process. At that point, the blood could be dried and made into a powder. “And then we can rehydrate the blood and have it return back to normal.”
Kopechek said the technique could be ready for clinical trials in three to five years. If successful, it could be used to create stores of dried blood in case of future pandemics or natural disasters—and for humanitarian aid work, military operations or even missions to Mars. Maybe first aid kits on Mars will include dried red blood cells.

22、 We’ve known for years that plants can see, hear, smell and communicate with chemicals. Now, reported New Scientist, they have been recorded making sounds when stressed.
In a yet-to-be-published study, Itzhak Khait and his team at Tel Aviv University, in Israel, found that tomato and tobacco plants can make ultrasonic(超声的)noises. The plants “cry out” due to lack of water, or when their stems are cut. It’s just too high-pitched(音调高的)for humans to hear.
Microphones placed 10 centimeters away from the plants picked up sounds in the ultrasonic range of 20 to 100 kilohertz(千赫兹). Human hearing usually ranges from 20 hertz to 20 kilohertz. “These findings can alter the way we think about the plant kingdom,” they wrote.
On average, “thirsty” tomato plants made 35 sounds an hour, while tobacco plants made 11. When plant stems were cut, tomato plants made an average of 25 sounds in the following hour, and tobacco plants 15. Unstressed plants produced fewer than one sound per hour, on average.
Perhaps most interestingly, different types of stress led to different sounds. The researchers trained a machine-learning model to separate the plants’ sounds from those of the wind, rain and other noises of the greenhouse. In most cases, it correctly identified whether the stress was caused by dryness or a cut, based on a sound’s intensity and frequency. Water-hungry tobacco appears to make louder sounds than cut tobacco, for example. Although Khait and his colleagues only looked at tomato and tobacco plants, they think other plants also make sounds when stressed.
If farmers could hear these sounds, said the team, they could give water to the plants that need it most. As climate change causes more droughts, they said this would be important information for farmers. “The sounds that drought-stressed plants make could be used in precision agriculture(精准农业),” said Anne Visscher at the Royal Botanic Gardens, Kew, in the UK.
Khait’s report also suggests that insects and mammals can hear the sounds up to 5 meters away and respond. For example, a moth may decide not to lay eggs on a water-stressed plant. Edward Farmer, at the University of Lausanne, Switzerland, is doubtful. He said that the idea of moths listening to plants is “a little too speculative”.
If plants are screaming for fear of their survival, should we be thankful we can’t hear them?
【1】What did Khait and his team find from their research?
A.Plants made low-pitched sounds when in danger.
B.Plants were able to produce sounds in response to stresses.
C.Plants picked up a wider range of sounds when stressed.
D.Plants made ultrasonic noises to communicate with each other.

24、 Back when the Mississippi River flowed wild, its ever-changing waters moved soil across the North American continent. It picked up sand and dirt in the north and brought it to the southern areas of what we now call the state of Louisiana. Thousands of years later, man-made barriers called levees (防洪堤) and flood-control systems control the powerful river. But Louisiana officials are making plans to use the Mississippi River’s ancient power to build new land as a way to ease the threat of rising seas.
Engineers hope to remake the destroyed low-lying lands by copying nature—digging into the levees and redirecting the water. The water holds a lot of small dirt sediments (沉淀物). The sediments can flow into coastal basins.
Some critics question whether the idea presents its own environmental risks. But if it does work, the project would rebuild an important protection against storm waves. It would also help the land provide new living areas for birds and fish that depend on wetlands.
Saltwater is destroying the coast. Pathways cut for oil and gas development, boat travel and logging have worsened the problem. The state estimates that it has lost about 518,000 hectares of land since 1932. If nothing is done, more than twice that much land could disappear over the next 50 years.
Experts and officials have discussed the idea of using the river to rebuild the coast for many years. But it was not until money became available from the 2010 BP oil spill that the plan began to really take shape. In 2010, an explosion killed 11 people on an oil rig (石油钻塔) off the Gulf Coast that energy company BP operated. Millions of gallons of oil then flowed into the water over the next three months.
One year later, the United States government ruled that BP was responsible for the accident,
The company was ordered to pay billions of dollars for the damage. Louisiana is putting much of its share of the money toward coastal restoration.
【1】What advantage will the new land bring?
A.Preventing severe drought.
B.Creating habitats for animals.
C.Controlling the powerful river.
D.Increasing the northern farm land.
【2】What can cause the coast to disappear faster?
A.Energy changes.
B.Destroyed levees.
C.Man-made disasters.
D.Man-made water protection systems.
【3】What made the plan of rebuilding the coast land come into effect?
A.The restoration of an oil rig.
B.The payment of compensation by BP.
C.The strong demand from oil companies.
D.The special support from some local critics.
【4】What can be a suitable title for the text?
A.Use Nature Power to Stop Soil Losing
B.Let the River Go Back to Its Original State
C.Fight Coastal Destruction by Copying Nature
D.Remove the Man-Made Barriers from the River
