Making beers on the moon might seem like a pipe dream to many, but for a group of students from the University of California at San Diego, there is a chance to take their research beyond Earth’s surface.
The Lab2Moon competition, held by TeamIndus, is offering students the chance to secure a spot on the TeamIndus rocket this year.
Taking craft beer to the next level, the students want to test whether it’s possible for yeast(酵母) to work and create beer on the moon. However, they believe the experiment is not just a creative concept for astronauts, it’s also important for the development of drugs and yeast-containing food, like bread.
“The idea started out with a few laughs among a group of friends,” said Neeki Ashari, a fifth-year bioengineering students at UC San Diego. “We all appreciate the craft beer. When we heard that there was an opportunity to design an experiment that would go up on India’s moonlander, w e thought we could combine our hobby with the competition by focusing on the practicality of yeast in outer space.”
The preparation work for the beer — up to the stage of adding yeast — will all be done on Earth, and rather than separating the fermentation ( 发酵) and carbonation stage of making beer, the team plans to combine them.
This removes the need to release CO2 accumulated in the process, which may result in cleanliness and safety issues out in space.
If selected, Team Original Gravity will be the first to make beer in outer space, and the fermentation will take place in a container no bigger than a soda can.
All teams competing for the place will showcase their ideas in Bangalore, India, in March.
Sadly, you won’t be enjoying moon beer in your local craft beer bar anytime soon, as no samples will be brought back. However, this small experiment could provide important data on just how practical it is for us to make and create our own resources on other planets and moons by learning how consumables (消耗品) behave in different environments.

Financial regulations in Britain have imposed a rather unusual rule on the bosses of big banks. Starting next year, any guaranteed bonus of top executives could be delayed 10 years if their banks are under investigation for wrongdoing. The main purpose of this “clawback” rule is to hold bankers responsible for harmful risk-taking and to restore public trust in financial institution. Yet officials also hope for a much larger benefit: more long-term decision-making not only by banks but also by all corporations, to build a stronger economy for future generations.
“Short-termism” or the desire for quick profits, has worsened in publicly traded companies, says the Bank of England’s top economist, Andrew Haldane. He quotes a giant of classical economies, Alfred Marshall, in describing this financial impatience as acting like “Children who pick the strawberries out of their pudding to eat them at once” rather than putting them aside to be eaten last.
The average time for holding a stock in both the United States and Britain, he notes, has dropped from seven years to seven months in recent decades. Transient(短期的) investors, who demand high quarterly profits from companies, can hold back a firm’s efforts to invest in long-term research or to build up customer loyalty. This has been called “quarterly capitalism”.
In addition, new digital technologies have allowed more rapid trading of equities( 股 票 ), quicker use of information, and thus shortens attention spans in financial markets. “There seems to be an advantage of short-term thinking at the expense of long-term investing,” said Commissioner Daniel Gallagher of the US Securities and Exchange Commission in speech this week.
In the US, the Sarbanes-Oxley Act of 2002 has pushed most public companies to delay performance bonuses for senior executives by about a year, slightly helping reduce “short-termism.” In its latest survey of CEO pay, The Wall Street Journal finds that “a substantial part” of executive pay is now tied to performance.
Much more could be done to encourage “long-termism,” such as changes in the tax code and quicker disclosure(披露) of stock acquisitions. In France, shareholders who hold onto a company investment for at least two years can sometimes earn more voting rights in a company.
Within companies, the right compensation design can provide motivation for executives to think beyond their own time at the company and on behalf of all shareholders. Britain’s new rule is a reminder to bankers that society has an interest in their performance, not just for the short term but for the long term.
1.According to Paragraph 1, one reason for imposing the new rule is the _______.
A.enhance banker’s sense of responsibility
B.help corporations achieve larger profits
C.build a new system of financial regulation
D.guarantee the bonuses of top executives
2.It is argued that the influence of transient investment on public companies can be _______.

B.the significance of long-term thinking.
C.the approaches to promoting “long-termism”
D.the popularity of short-term thinking.
4.Which of the following would be the best title for the text?
A.Failure of Quarterly Capitalism
B.Patience as a Corporate Virtue
C.Decisiveness Required of Top Executives
D.Frustration of Risk-taking Bankers
People diet to look more attractive. Fish diet to avoid being beaten up, thrown out of their social group, and getting eaten as a result. That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists.
The research team has discovered that subordinate (隶属的)fish voluntarily diet to avoid challenging their larger competitors. “In studying gobies we noticed that only the largest two individuals, a male and female, had breeding(繁殖) rights within the group, ”explains Marian Wong. “All other group members are non-breeding females, each being 5–10% smaller than its next largest competitor. We wanted to find out how they keep this size separation.”
The reason for the size difference was easy to see. Once a subordinate fish grows to within 5–10% of the size of its larger competitor, it causes a fight which usually ends in the smaller goby being driven away from the group. More often than not, the evicted fish is then eaten up.
It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish. Whether they did so voluntarily，by limiting how much they ate, was not clear. The research team decided to do an experiment. They tried to fatten up some of the subordinate gobies to see what happened. To their surprise，the gobies simply refused the extra food they were offered，clearly preferring to remain small and avoid fights, over having a feast.
The discovery challenges the traditional scientific view of how boss individuals keep their position in a group. Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves, so keeping their competitors small.
While the habits of gobies may seem a little mysterious, Dr. Wong explains that understanding the relationships between boss and subordinate animals is important to understanding how hierarchical (等级的) societies remain stable.
The research has proved the fact that voluntary dieting is a habit far from exclusive(排他的) to humans. “As yet, we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature,” the researchers comment. “Data on human dieting suggests that, while humans generally diet to improve health or increase attractiveness, rarely does it improve long term health and males regularly prefer females that are fatter than the females’ own ideal.”

Three years ago. I was arranged to work for a few weeks as a dentist in a new dental clinic at Victor Harbor, to the south of Adelaide and an hour further away than my usual workplace. My first day there was rush driving to a new and unfamiliar clinic and getting used to the different rules and clinical environment.
In my worry and anxiety, and feeling a little unfamiliar in the new setting, I removed my three things: my wedding ring, a ring that belonged to my mother and one that was an anniversary gift from my husband. I wrapped them in a tissue(纸巾) and placed them beside my computer.
During my lunch break, I noticed the wrinkled tissue and thought that it didn’t look very neat and dropped it into the rubbish bin. I went about my duties and my day went on well; I met new patients and felt that I had been productive and efficient. Driving home at the end of the day, just moments before I reached my house, I noticed that I was missing my rings. I felt the heart in my body rose, my cheeks burning red. I went inside and tried to calm down. I felt sick to my stomach and I had that sinking feeling in my heart. I spent an hour or so making calls trying to follow the track of my rings. The first people I called was my manager and clinical leader and they gave me a few contact numbers for cleaners. I got in touch with a lady who managed the cleaning services for the clinic and she informed me that the bins had already been collected.
Heartbroken, I knew nothing could be done now. I had lost my wedding ring and one of my most treasured rings my mother’s wedding ring. Had it not been for my carelessness, all this would not have happened. With great sorrow and regret, I just sat there rooted in my chair.
Paragraph 1:
After two hours or so, I received a most amazing phone call. _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Paragraph 2:
I decided to thank the wonderful person face to face. _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
