There was great excitement on the planet of Venus (金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs.

    The satellite was directed into an area known as Manhattan (曼哈顿). Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information about the feasibility of a manned flying saucer (飞碟) landing on Earth. A press conference was held at the Venus Institute of Technology.

“We have come to the conclusion, based on last week's satellite landing,” Professor Zog said, “that there is no life on Earth."

    “How do you know this?” the science reporter of the Venus Evening News asked.

    "For one thing, Earth's surface in the area of Manhattan consists of solid concrete (混泥土) and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.”

    “Are there any other sources of danger that you have discovered in your studies?”

    “Take a look at this photo. You see this dark black cloud staying over the surface of Earth? We don't know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there. Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink.”

    “Sir, what are all those tiny black spots on the photographs?”

    “We're not certain. They seem to be metal objects that moves along certain roads. They give out gases, make noise and keep crashing into each other.”

    “Professor Zog, why are we spending billions and billions of Zilches to land a flying saucer on Earth when there is no life there?”

    “Because if we Venusians can learn to breathe in the Earth atmosphere, then we can live anywhere.”

    I grew up in Bensonhurst, Brooklyn. When the holiday decorations went up, there were houses on my block with trees lit up for Christmas in front yards and behind living room windows. I was born in a Jewish family. Even though I received eight presents for Hanukkah (an eight-day Jewish holiday in November or December), it just wasn't fair. My friends had beautiful trees with lights and presents brought by a man in a red suit. I didn't have a tree, and I lived in an apartment building, so I had no chimney(烟囱).

    That year, some neighbors bought a Christmas tree, but it was too tall for their living rooms. They cut off the top and, knowing I wanted to celebrate Christmas, gave the top to my family. After my parents fell asleep, I opened a window in our apartment. I imagined Santa could park his sleigh(雪橇) on our fire escape. When I woke up the next morning, the window was closed and Santa had delivered a present. I can't even remember what it was, but my memory of the morning lasts.

    My relationship with Santa took a break until my daughter, Amanda, was born in 1992. My wife and I saw no reason to deprive(剥夺) her of meeting Santa. In 1998, a friend of mine portrayed(扮演) Santa at the South Street Seaport in Manhattan. He told me to stop by with my wife and daughter, and asked for their names in advance so he could greet them. When he saw us at the seaport, he greeted us by our names. My daughter's mouth opened wide and she pulled back. Maybe she was too young to appreciate this. But other families waiting to see him seemed delighted by his appearance and the gifts he brought.

    My two children are now grown up and do not visit Santa, and we do not have a Christmas tree, yet our family still enjoys the holiday. On Christmas Eve, in the spirit of the night, we leave a plate of my favorite cookies on the kitchen table in hopes Santa will leave a present.

    Vinegar is great. It makes salad, fries and dumplings taste better, and you can even clean your windows with it. And now, according to scientists, it may even help the planet's population to ease hunger.

    Researchers from the RIKEN Center for Sustainable Resource Science (CSRS) in Japan found that growing plants in vinegar makes them more resistant to droughts.

    This could mean that in the future, worries about climate change affecting the world's supply of food will be much lower.

    The discovery was made after the researchers studied the Arabidopsis, a plant known for its ability to survive in dry weather. It was found that when the plant was placed in drought-like conditions, it produced a chemical called acetate(醋酸盐) – the main component of vinegar.

    After discovering this, the scientists experimented further by adding acetate to the soil of other plants, before they stopped giving them water completely. After leaving the plants for 14 days, they found that the ones treated with acetate had survived, while the untreated plants had dried up and died. It's hoped that this simple method of survival could soon be used to help farmers in dry countries keep their crops alive.

    Jong Myong Kim, co-author of the study, told Popular Science magazine that he's already been in touch with people all over the world who are interested in trying this simple and cost-effective method out for themselves from flower growing companies to amateur gardeners.

    Although at this point keeping thirsty plants alive isn't as easy as just pouring vinegar over them, Kim said he and his team are working on making the process as simple as possible. "Now we are trying to cooperate with some farmers, and also some companies, to make a method to apply this system." he said.

    And for those of us who always forget to ask our neighbors to water our plants when we go away, hopefully this means the end of returning home from a trip to find our favorite flowers have died.

Researchers at MT created a high-tech pill that starts to vibrate(震动) once it makes contact with liquid in the user's stomach and make him or her feel full. The pill was reportedly thought up by Shriya Srinivasan, currently an assistant professor of bioengineering at Harvard University.

VIBES, short for Vibrating Ingestible BioElectronic Stimulator，was only recently made public in a study published in the Science Journal, but it is already being announced by the media as the future of weight loss. Although it has yet to be tested on humans, trials on pigs have achieved very hopeful results. After about 30 minutes of VIBES activity, pigs consumed on average almost 40 percent less food in the next half hour than they did without the smart pill. Apparently, the revolutionary device works by activating stretch receptors in the stomach, modeling the presence of food. This in turn signals the hypothalamus(下丘脑) to increase the levels of hormones that make us feel full. The vibrating stimulator, which is about the size of a vitamin pill, is powered by an encased battery and activated either by the gastric fluid(胃液) breaking down a coat around the pill, or by an incorporated timer. After producing the desired effect, the pill exits the body with other solid waste.

The good news is that it is expected to have a cost in the cents to one dollar range, and researchers say that it may eventually be possible to implant the stimulator and thus remove the need for people to constantly swallow it.

"Our study demonstrates the effectiveness of a low-cost, non-operative intervention to reduce food intake and calorie consumption. The device functions effectively in the stomach and leading to fullness," said Giovanni Traverso, co-author of the study. "The device has the potential to revolutionize options for weight loss treatment. However, future studies will need to explore the physiological effects of the device before it's available for patients."

Researchers are now exploring ways to scale up the producing of VIBES capsules which could enable clinical trials in humans.
