It's known as the place where many companies across the globe show their latest technology offerings. Here is a look at some of the top products presented at CES 2022.
Electronics maker AirSelfie launched its latest self-flying camera designed to take "selfie" pictures. The new device, called Air Pix, is a small, light camera that flies through the air and takes high-quality photographs and videos. A video on the company's website explains that Air Pix can fly, frame and take pictures all by itself before landing back on the user's hand.
Labrador's assistive robotRobot maker Labrador announced the launch of its Retriever robot. The small, self-driving machine is designed to hold things and, as its name suggests, also retrieve (取回) things. The robot can be controlled by voice commands or from an app on a phone. It can also be programmed based on an exact map of a user's home. The company says the Retriever is designed "to serve as an extra pair of hands and lighten the load of everyday tasks in the home".
Self-driving tractorAmerican-based farm equipment producer John Deere presented a fully self-driving tractor. The company says the vehicle is equipped with six different cameras and a series of sensors to guide the tractor through the fields. Farmers can control the vehicle and see the tractor's progress in real time through a mobile device. John Deere says the concept is to help farmers do more work with fewer tools and other people.
Most rain forests lie to the equator(赤道), where the climate is often mild and there are long hours of sunshine. The warmth of the land heats the air above, causing it to rise and tiny drops of water to fall as rain. The rainfall can reach at least 98 inches a year. This wet, warm world with plenty of sunlight is perfect for plants to grow, so the trees grow fast with green leaves all the year round. The trees themselves also have an effect on the climate. They gather water from the soil and pass it out into the air through their leaves. The wet air then forms clouds, which hang over the treetops like smoke. These clouds protect the forest from the daytime heat and night-time cold of nearby deserts, keeping temperatures fit for plant growth.
Rain forests slightly farther away from the equator remain just as warm, but they have a dry season of three months or more when little rain falls. Tree leaves fall during this dry season and new leaves grow when the wet season or monsoon(雨季) begins. Thus these areas are known as the "monsoon forest".
Another type of rain forest grows on tropical mountains. It is often called the "cloud forest" because clouds often hang over the trees like fog.
The rain forest is the ideal place for the growth of many different trees. Most of them depend on animals to eat their fruits and spread their seeds. When the fruits are eaten, the seeds inside them go undamaged through animals' stomachs and are passed out in their droppings. The seeds lying on the forest floor then grow into new trees.
The World Health Organization warns that millions of people are dying every year from indoor air pollution. Nearly three billion people are unable to use clean fuels and technologies for cooking, heating as well as lighting.
These findings show that the use of deadly fuels in inefficient stoves, space heaters or lights is to blame for many of these deaths.
WHO officials say indoor pollution leads to early deaths from stroke, heart and lung disease, childhood pneumonia(小儿肺炎) and lung cancer. Women and girls are the main victims. These diseases can often result from the burning of solid fuels. These fuels include wood, coal, animal waste, crop waste and charcoal.
The United Nations found that more than 95 percent of households in sub-Saharan Africa depend on solid fuels for cooking. It says huge populations in India, China and Latin American countries, such as Guatermala and Peru, are also at risk.
Nigel Brace is a professor of Public Health at the University of Liverpool. He says researchers are developing good cook-stoves and other equipment to burn fuels in a more efficient way. There are already multiple technologies available for use in clean fuels, There is really quite an effective and reasonably low-cost alcohol stove made by Dometic (a Sweden-based company) that is now being tested out. LPG (Liquefield Petroleum Gas) cook is obviously widely available and efforts are under way to make those efficient. Another interesting development is electric induction stoves (电磁炉). WHO experts note that some new, safe and low-cost technologies that could help are already available. In India, you can buy an induction stove for about $8. 00. And in Africa you can buy a solar lamp for less than $1. 00.
But this, the agency says, is just a start. It is urging developing countries to use cleaner fuels and increase access to cleaner and more modern cooking and heating appliances/devices.
Scientists in Argentina have created the world's first cow with two human genes that will enable it to produce human-like milk.
Genetic engineering was used to introduce the "mothers' milk" genes into the animal before birth, according to the National Institute of Agribusiness Technology in Buenos Aires.
As an adult, the cloned cow "will produce milk that is similar to that of humans", which will prove "a development of great importance for the nutrition of infants(婴儿)", said the institute. "The cloned cow, named Rosita ISA, is the first in the world with two human genes that contain the proteins present in human milk," said the statement.
In April, scientists in China published details of research showing that they had created dairy cows which produced milk containing proteins found in human breast milk. But the Argentine team said the Chinese only introduced one human gene, while their research involved two, meaning the milk will more closely resemble that of humans.
"Our goal was to raise the nutrition value of cows' milk by adding two human genes, which do good to the immune system of infants," said Adrian Mutto, from the National University of San Martin which worked with the institute.
Cristina Kirchner, President of Argentina, said that the scientific institute made all Argentines proud. She also said that she had refused the "honor" of having the cow named after her. "They came to tell me that the name is Cristina, but what woman would like to have a cow named after her? It appeared to me to be more proper to call it Rosita. "

A month before my first marathon, one of my ankles was injured and this meant not running for two weeks, leaving me only two weeks to train. Yet, I was determined to go ahead.
The idea that I was "not athletic" stuck with me for years. When I started running in my 30s, I realized running was a battle against my own body and mind.
The night before my marathon, I had a nightmare that I couldn't even cross the finish line. I woke up sweating and nervous. My wife still encouraged me to prove something to myself. She is my biggest fan, who never minded the alarm clock at 4 a. m. or questioned my expenses on running.
It was winter but people from all walks of life crowed along the course, enjoying the marathon in their own ways. Without a cloud in the sky, the light took on a magical color. Shortly after embarking on the journey, my shoelaces became untied, so I stopped to readjust. Not the start I wanted!
At mile 3, I passed a sign: "GO FOR IT, RUNNERS!"
By Mile 17, I became out of breath and the once injured ankle hurt badly, for which I had prepared myself well in advance. Despite the pain, I stayed the course walking a bit and then running again.
By mile 21, I was starving! The only thing I could do to strengthen my body was to take a few sips of water. I realized that I was left behind, but it didn't matter a bit to me, because I kept telling myself that it was not a competition with other participants, but a test of will.
As I approached mile23, I couldn't feel my feet anymore, feeling like floating in the air. However, what happened next second changed this ordinary day—immediately a vehicle lost its control and dived into the canal (运河) beside the course! The crowds just rushed to the bank and saw a woman behind the wheel in the sinking car.
