3 . Sending human travelers to Mars would require scientists and engineers to overcome a range of technological and safety obstacles. One of them is the serious risk posed by particle radiation (辐射) from the sun, distant stars and galaxies (星系).
Answering two key questions would go a long way toward overcoming that difficulty: Would particle radiation pose too serious a threat to human life throughout a round trip to the red planet? And, could the very timing of a mission to Mars help shield astronauts and the spacecraft from the radiation?
In a new article published in the journal Space Weather, an international team of space scientists, including researchers from UCLA, answers those two questions with a “no” and a “yes.” That is, humans should be able to safely travel to and from Mars, only if the spacecraft has enough protection and the round trip is shorter than approximately four years. And the timing of a human mission to Mars would indeed make a difference: The scientists determined that the best time for a flight to leave Earth would be when solar activity is at its peak (高峰期), because, during this period, the most dangerous and energetic particles from distant galaxies are deflected (偏转) by the enhanced solar activity.
A trip of that length would be imaginable. The average flight to Mars takes about nine months, so depending on the timing of launch and available fuel, it is reasonable that a human mission could reach the planet and return to Earth in less than two years, according to Yuri Shprits, a UCLA research geophysicist and co–author of the paper.
“This study shows that while space radiation impose (强加) strict limitations on how heavy the spacecraft can be and the time of launch, and it presents technological difficulties for human missions to Mars, such a mission is possible,” said Shprits, who also is head of space physics and space weather at GFZ Research Centre for Geosciences in Potsdam, Germany.

4 . Filming in the Wasatch-Cache National Forest
The Kamas Ranger District handles film permits for the Kamas district of the Wasatch- Cache National Forest.
To ensure that permits are issued in time for filming, the Forest Service requests that application form be handed in three to four weeks prior to filming.
The fee structure for filming in the National Forest is as follows:
Filming Special Use Fee1 to 10 people-$150 per day
11 to 30 people-$200 per day
31 to 60 people-$500 per day
Over 61 people-$600 per day
Film Monitoring Fee
1 day filming-FREE
Extra days-$200 per day
Additional FeesAdditional fees will be charged in the following situations:
Large production (greater than 100 people), multiple site filming that may require additional film monitoring to protect natural resources and a performance agreement in the form of a deposited check.
Upon approval, a Special Use Permit will be issued with a bill for collection. Checks should be made payable to “USDA Forest Service, ” and payment must be received before filming.
NoteSome areas of the forest are especially sensitive to impacts from vehicles, domestic animals, and people. These areas include wetlands, streams, lake shorelines, and most meadow areas. Filming requests in these sensitive areas will require special surveys to determine possible environmental impacts. The request may be denied.

5 . Born in Congo, Dieuveil grew up in Germany and began his career in some of Europe’s best establishments. He opened his restaurant Meza Malonga in 2020, where dinner is not just a meal but also a tour of the African continent. Delicately plated dishes feature the Nile perch from Uganda, Algerian olive oil, and Penja pepper from Cameroon. By combining ingredients and food cultures from different countries in Africa with some modern elements, Dieuveil has created his own cuisine that represents not only the heritage and traditions of a vast and varied, continent but also the latest trends. Undoubtedly, such integration has received international applause.
However, Dieuveil’s ambitions are not just for himself. After setting up the digital platform “Chefs in Africa”, which to date has connected over 4,000 professional chefs to career opportunities and the skill development, Dieuveil created a training school to produce the next generation of cooking pioneers. He is on a mission to lay the foundations of an innovative fine-dining scene on the African continent that can compare with Europe’s — but in a distinctive, African way.
When it comes to the understanding of fine dining, different from Europe’s emphasis on exclusivity and competitiveness, Dieuveil focuses more on integration. “If you want to go far, you must share with people,” he says. And his Afro-fusion cuisine has been shaped by this philosophy of sharing. To better understand the diverse traditions, dishes and ingredients of Africa, he went into villages and met with the grandmothers, as they’re usually the masters of amazing, old techniques. These villagers shared their local cuisine and family recipes, teaching Dieuveil regional fermentation (发酵) and preservation processes.
To ensure the quality of fresh produce, Dieuveil sources all his vegetables from his three-hectare organic farm in northern Rwanda, where he continues his “food revolution” by establishing the connection with remote and underserved communities, and involving more students coming from countries across Africa. He said, “Africa is the garden of the world and has an amazing diversity of food. What is happening now with African cuisine and the exposure we are getting are clear indications that our food revolution is already here.”

7 . In early October, Travis Gienger transported an enormous pumpkin (南瓜) from his home in Minnesota to the World Championship Pumpkin Weigh-Off in California. His pumpkin set the record for the biggest one ever grown in North America. How do competitive growers get their pumpkins to grow to massive sizes?
Gienger, who teaches horticulture (园艺学) at Anoka Technical College, begins growing his pumpkins in mid-April, starting with seeds that he grows indoors for the first few weeks, when Minnesota’s soil is too frosty.
Depending on the variety, pumpkin plants can grow up to a dozen fruits on a single vine (藤曼) . But to maximize size, growers remove all but one or two of these pumpkins in order to decrease each individual fruit’s competition for resources.
But what exactly happens inside a pumpkin as it grows? Two factors drive natural growth: cell division and cell expansion. Cell division accounts for most of the growth at the beginning of a fruit’s life. This period lasts for about 20 days in pumpkin plants.
A.Biology has the answers. |
B.Genetics also influences pumpkin growth. |
C.The following tips will give you a head start. |
D.Once it warms up, the plants are transferred outside. |
E.When it stops, cell expansion will then come into play. |
F.Growers extend the growth period for as long as possible. |
G.Growers also remove the weeds in the area for the same reason. |
