How AI Protects Us
We should consider AI not as something competing with us, but as something that can strengthen our abilities. 1. And it might help keep us safe in the 21st century.
Predict infectious (传染性的) diseases
The AI in medicine is a system that combines the time and location of each new infectious disease. “These are all factors that determine how the disease will spread,” explains a researcher. 2. It will allow public health officials to take action early for locals.
Keep hunger from the door
Researchers develop an automated system aimed at fighting against diseases in crops. The Mcrops project allows local farmers to take pictures of their plants and use computers that have been trained to spot the signs of the four main diseases that are responsible for damaging crops. 3.
Fight cancer
Cancer causes more than 8.8 million deaths worldwide and 14 million people are diagnosed with some form of cancer every year. 4. Now Google and IBM have been applying their AI technology to this problem.

The task of balancing power supplies is getting harder. The spread of smart meters — digital energy monitors that automatically record usage - is also providing more data than ever about how and when consumers use energy. The EU alone plans to have 500 million smart meters in homes by 2020.
A.Record the locations smartly.
B.Keep the balance of power supplies
C.Thus, the farmers can have a good harvest.
D.The system can also help to predict the disease.
E.This is because AI has an ability that’s far beyond humans.
F.But now people have no ideas how to deal with the terrible problem.
G.Yet catching cancers as early as possible can greatly improve a patient’s chances of survival.
Role models (榜样) are important for inspiring (鼓舞) scientists, but new research suggests that scientists who are known for their hard work are more motivating (激励人的) than scientists who are viewed as naturally brilliant.
In a series of studies, researchers found that young people were more motivated by scientists whose success was connected with effort than those whose success was because of born intelligence, even if that scientist was Albert Einstein.
Danfei Hu, a doctoral student at Penn State, and Janet N. Ann, an assistant professor of psychology at William Paterson University, said the findings — recently published in Basic and Applied Social Psychology — will help deal with certain secret about what it takes to succeed in science.
According to the researchers, there is concern in the science community with the number of students who run after careers in science during school only to drop out from those career paths once they graduate from college. To help solve the problem, Hu and Ahn wanted to research role modeling (行为榜样), which gives the students specific goals, behaviors or strategies (策略) they can follow.
The researchers performed studies with 176, and 162 participants (参与者) in each, respectively. In the first study, all participants read the same story about common struggles a scientist met in their science career. However, half were told the story was about Einstein, while half were told it was about Thomas Edison. Although the stories are the same, participants were more likely to believe natural brilliance (才华) was the reason for Einstein’s success. In addition, the participants who believed the story was about Edison were more motivated to complete a series of math problems.
“This proved that people generally seem to view Einstein as a genius, with his success commonly linked to extraordinary talent,” Hu said. “Edison, on the other hand, is known for failing more than 1,000 times when trying to create the light bulb, and his success is usually linked to his effort.” Hu added, “Knowing that something great can be achieved through hard work and effort, more students will step into science confidently. “

The US film industry may have generated profits somewhere in the region of $40 billion last year, but it seems Hollywood still has plenty of work to do if wants to compete with the most popular American institution: the public library.
Yes, according to a recent Gallup poll (民意调查), which was the first such survey since 2001, visiting the local library remains by far the most common cultural activity American join in. As reported earlier today by Justin McCarthy:
“Visiting the library remains the most common cultural activity American join in, by far. The average 10.5 trips to the library US adults report taking in 2019 exceeds their participation in eight other common leisure activities. Americans attend live music or theatrical events and visit national or historic parks roughly four times a year on average and visit museums and gambling casinos (赌场) 2.5 times annually. Trips to amusement or theme parks (1.5) and zoos (0.9) are the least common on activities among this list.”
The results of the Gallup poll have been broken down in a range of different ways, all of which you can peruse (研读) at your leisure, but two of the more interesting, though unsurprising, findings are that women report visiting the library nearly twice as frequently as men do, and that libraries are visited most by adults in low-income households and least by adults in high-income households.
Congratulations to all you librarians out there; keep fighting the good fight. Pour one out for the zookeepers, though; it appears the zookeepers may be jealous and feel it not worth staying at the zoo.

Lee Spargo initially set up an outdoor trail camera at his home near Mount Holly in hopes of catching a wild fox that had been hunting his chickens. But he was aware of another danger Tuesday night when the camera caught footage of his house being swallowed in flames.
A fire inside Lee’s home triggered (触发) the camera and sent an alarm to his phone around 2:22 a.m. Lee woke up thinking he had caught the fox, but soon realized that his house was on fire instead.
“If I didn’t set up the equipment, we’d all be dead. It saved our lives,” he said. “I got up, Thinking ‘Oh, the fox is out there and I’m going to get him’. And then I saw a big reflection in the kitchen and I was considering, ‘What’s that?’”

There are so many websites to help you plan trips and book trips and save money.
1. Dishtip.com
If I had to pick just one site to help with restaurant recommendations around the US, it would be Dishtip.com. Dishtip organizes the information of eating out in the United States in a whole new way: In other words, the site sorts through reviews across the web, such as the best dishes in Denver or the pizzas in Portland or the fried food in Phoenix.
2. Skypicker.com
Skypicker.com basically helps you figure out where you can fly within your budget. It’s sort of like the “explore” page of Kayak.com, but focuses mainly on Europe, and on very, very cheap flights.
3. Stay.com
I usually doubt the sites that claim (声称) they can plan your trip for you. But for a quick agenda with a few useful extras, Stay.com is not bad at all. Here’s what you do: Choose one of more than 100 destinations, from Provence to Marrakesh to Lake Tahoe. Then go through their listings of top attractions, museums, shopping, restaurants and something else, clicking on whatever appeals to you. Those choices magically turn into a personalized plan that you can either turn into a pdf file and print or send to your smart-phone, where with the Stay. com app you can use it, and the city map that comes with it, even when you’re offline.
