    Google's new artificial intelligence can defeat both humans and other AIs. Fortunately, the only war zone where it fights and wins is the ancient board game Go（围棋）.

    AlphaGo Zero, developed by Google-owned DeepMind, is the latest AI program. The original AlphaGo defeated Go master Lee Sedol last year, and AlphaGo Master, an updated version, went on to win 60 games against top human players. What's different about AlphaGo Zero is that it became potentially the world's best Go player without any help from humans.

    The program AlphaGo Zero started off knowing only the basic rules and then played millions of games against itself in just a few days. After almost five million games played against itself, AlphaGo Zero could outplay humans and the original AlphaGo. After 40 days, it was capable of beating AlphaGo Master.

The program learned the strategies humans accumulated over thousands of years in a matter weeks and also developed nontraditional strategies and moves that beat the techniques of the human masters, leaving them astonished. "At each stage of the game, it seems to gain a bit here and lose a bit there, but somehow it ends up slightly ahead, as if by magic," said Andrew Jackson of the American Go Association

    DeepMind says it has plans for the technology behind AlphaGo Zero beyond just defeating all over an ancient game board. "In the end, we want to apply these breakthroughs to helping solve all sorts of pressing real world problems like designing new materials," said Demis Hassabis, co-founder and CEO of DeepMind, in a statement.

    That sounds great, but just as a precaution, let's take the advice of Elon Musk and Stephen Hawking and keep any super-fast learning AI away from the nuclear launch codes for now.

    Parents often say that they don't mind what their children do in life just as long as they are happy. Happiness and pleasure are almost universally seen as among the most precious human goods. {#blank#}1{#/blank#}

    Philosopher Jeremy Bentham believed that all sources of pleasure are of equal quality, but John Stuart Mill disagreed. Mill argued for a difference between higher and lower pleasure. {#blank#}2{#/blank#} Lower pleasure, in contrast, requires mere（仅仅的, 纯粹的）senses.

    The entire debate assumes a clear divide between the physical and the mental. {#blank#}3{#/blank#}What will it mean for our ideas about pleasure?

    {#blank#}4{#/blank#}Food is usually considered to the lower pleasure. All animals cat, using the senses of smell and taste. It doesn't require ay complex cognition（认知）to conclude that something is delicious. However these people failed to appreciate something that he French food writer Jean Anthelme Brillat-Savarin captured. That is," Animals feed, man cats, only the man of intellect （才智）knows how to eat."

    Eating shows that the difference between higher pleasure and lower pleasure is not what you enjoy but how you enjoy it. {#blank#}5{#/blank#}Preparing it using the powers of reflection and attention turns it into a higher pleasure.

A. The dining table is a good place to start.

B. Wolfing down your food is a lower kind of pleasure.

C. What's the real difference between high and low pleasure?

D. What happens if the physical and the mental cannot be separated?

E. All philosophers believed that cookery could never be a form of art.

F. Higher pleasure depends on human abilities such as self-awareness or language use.

G. However, disagreements will be caused about whether some forms of pleasure are better than others.

    A new study suggests that patients with breast cancer who take additional vitamins during chemotherapy(化疗) treatment may face increased risks.

    Researchers said the use of dietary supplements(补充剂) that increase levels of antioxidants, iron, vitamin B12 and omega-3 fatty acids appeared to lower the effectiveness of chemotherapy. Researchers reported their findings in the Journal of Clinical Oncology.

    Christine Ambrosone is the head of cancer prevention and control at the Roswell Park Comprehensive Cancer Center in Buffalo, New York. She said, "From this study and others in the literature, it seems that it may not be wise to take supplements during chemotherapy."

    "It's thought that antioxidants might interfere with the ability of chemotherapy to kill cancer cells," Ambrosone said.

    Some doctors have been advising patients for a number of years not to take antioxidants during chemotherapy. "But there was no strong empirical data for that recommendation," Ambrosone said.

    So, Ambrosone and other researchers decided to study whether supplement use might affect chemotherapy's effectiveness. They looked for evidence in an earlier study on diet, exercise, lifestyle and cancer results.

    In the earlier research, people who took part were asked about their use of supplements at the beginning of and during treatment, and about their lifestyle, diet and exercise. The researchers studied 1,134 patients who filled out the surveys and followed them for a median of six years.

    The researchers searched for possibilities that might increase the risk of the disease reappearing or of death. They found that patients who took any supplements at the beginning of and during chemotherapy were 41 percent more likely to have their breast cancer return than those who did not. In addition, the supplement takers were 40 percent more likely to die later on compared to patients using no supplements. The supplements included vitamin A, C and E. Those taking vitamin B12 and iron supplements were at greater risk of cancer returning, the researchers said.

There are so many choices when you go shopping. You have to check the sell — by dates so that you know how long you can store and use the food you are purchasing.

But do you know that the best sell — by dates on food packaging don't really tell you if the food is safe to eat. The food may not last as long as it says if it isn't stored correctly at any point of the distribution chain. Now there is food packaging that can detect and change colors if the food has gone bad.

Each American wastes 103 pounds of spoiled food out of the refrigerator every year. The new smart packaging from Primitives Biodesign—a new company that operates out of a lab at Indibio, a biotech accelerator in San Francisco-can help to reduce this huge waste of food.

The basic material that doesn't contain sensing material is made from algae and can block oxygen more effectively than regular film, so the food stays fresher for a longer time. Since it is made from a natural substance, it can also break down in nature.

Making the film smart is the thorny part. Luckily, the team managed to use a process that is like the way nature responds to changes in the environment. The mechanism responds like the way flowers emit compounds to change colors.

"It could be supplement packaging that indicate when it's been tampered with by changing color to tell you that it's no ledger safe," says Kan. She explained that the new packaging can be used on food products to fell if the food has turned bad before someone has to smell or taste it.

The company has proven in lab tests that the technology works and now they are working on how to develop commercial uses for it. The added safety features will come out later. Helping to control food waste in products like meat or cheese which have high greenhouse gas emissions will also help to reduce climate change.
