2 . When you hear the word “artificial intelligence”, the first thing that comes to mind is robotics, but what truly is artificial intelligence and what does the future hold for it? Artificial intelligence is any device or machine that mimics cognitive (认知的) functions humans associate with the human mind, such as learning and problem solving. Examples of artificial intelligence in our day to day lives include: Siri, Google, advertising and so much more. Every industry is incorporating (吸收/包含) artificial intelligence into its back bone.

Currently, the effects of artificial intelligence seem all positive. Artificial intelligence will lead to more new and important discoveries in the future, through its predictive modelling. In 2017, NASA reported the discovery of an eight-planet solar system with the help of AI. It can also predict the emergence of any new virus, disease or epidemic and discover a corresponding drug to treat it by accessing and analyzing multiple sets of data. This in turn will help the healthcare industry develop Al programs that will improve longevity and predict the time of the first sign of diseases, improve drug research processes and assist doctors in diagnosis.

However, there are still a lot of public concerns. An article titled “The Future of Work” gives a practical view on the influence of artificial intelligence and automation in our job industry. It predicts that by 2030, job losses will reach a rate of twenty nine percent, with an even lesser job creation percentage of thirteen percent. In 2014, a chat bot known as Eugene Goostman passed the Turing test, making judges think it was a human and leading to a lot of raised concerns. Does this mean that with future research, robots can insert themselves smoothly into our environment? It gives people a lot of food for thought.

The future of artificial intelligence is both fascinating and alarming. Privacy laws and security guidelines should be reviewed to protect everyone from vulnerability (脆弱性). Still if researches continue to be done with exposure and responsibility, the balance would not tip in favor of the negative.

3 . Salad is good for you, generally speaking, so growing fresh greens in orbit seems like a winning way for space workers to stay healthy. New research suggests that as nutritious as space salad might be, it could pose something of a risk to astronauts.

The problem is growing leafy plants like lettuce (生菜) in space can come with a side dish of bacteria (细菌), according to a new study from a team at the University of Delaware. In tests on plants grown in modeled micro-gravity, they were shown to actually be more sensitive than normal to the Salmonella enterica (SE) (沙门氏菌).

We know that the International Space Station (ISS) is home to a lot of aggressive bacteria, and if these space virus were to cause widespread sickness in an astronaut crew, it would mean lives were at risk. “You don’t want the whole mission to fail just because of a food safety outbreak,” says plant biologist Harsh Bais from the University of Delaware.

Bais and his colleagues used a device to perform some clever rotation tricks in the lab, putting lettuce plants into a similar state as they would be in micro-gravity. They then added SE bacteria to the leaves. What was interesting — and surprising — was that the tiny stomata (气孔) in the lettuce opened up to allow the bacteria to get in. Ordinarily, the job of the stomata is to keep dangerous attackers out, while at the same time helping the plant to breathe.

The researchers then added a more helpful species of bacteria, one that typically protects plants from external stressors. Again, the defense didn’t work in micro-gravity — suggesting there’s something about this state that disables the chemical reactions that the lettuce would normally use to keep itself safe.

Add in what we know about space bacteria being particularly tricky, and this is a potential problem. The team behind the study wants to see a lot more research into making sure our foodstuffs are safe outside of orbit.

4 . At just a few inches long and living on an affordable diet of flakes, goldfish are often viewed as the world’s most unnoticeable pet — a kind of gateway animal to prepare new caregivers for cats and dogs to come. But their blank stare and expression cover up a little-known and somewhat horrifying fact: Released into the wild and upping their caloric count goldfish can develop into massive fish, damaging local ecosystems.

According to The New York Times, the Great Lakes are currently suffering from an inflow of goldfish. They eat everything from algae (海藻) to plants to animals without backbones and can reach 16 inches to 19 inches in length, weighing in at 4 pounds. And all that consumption is destructive. The goldfish swallow plants that native fish eat. They also consume algae, which promotes further algae growth. Because they’re resistant to changing water temperatures, they can be lasting trouble. They are also forcing native fish out of their natural habitat.

Researchers have observed a significant increase in the goldfish population over the past few decades, a likely consequence of people releasing pets that then reproduce. It’s possible that tens of millions of goldfish now live in the Great Lakes; similar goldfish problems have also been observed in Australia.

Possible interventions include electrical currents that would kill the fish and netting to capture them and control the population in breeding grounds identified by tracking.

Goldfish grew popular in the U.S. in the late 19th century,when the U.S. Commission on Fisheries gave away thousands of them in Washington D.C They’re fairly crafty fish with the capacity to learn some simple tricks. Advocates say the typical fishbowl is too small for them and recommend a tank of at least 20 gallons per fish so they have room to move.

With the right environment, goldfish can reproduce fast and live for decades. But if you’re not interested in keeping them, experts at the U.S. Fish and Wildlife Service suggest donating them to a school, pet store, or interested party — not a local pond.

6 . Artificial Intelligence (AI) has greatly sped up how long it takes to sort, label and analyze(分析) animal sounds—as well as to figure out which aspects of those sounds might carry meaning. One day we’ll be able to use AI to build a chat box that translates complex(复杂的) animal sounds into human language. Project CETI is just one organization working toward this goal.

“AI could eventually get us to the point where we understand animals, but that’s hard to deal with and long-term,” says Karen Bakker, a researcher at the University of British Columbia in Vancouver, Canada. “Some species have been on the planet longer than humans. Some species could go extinct before we figure out their language,” Bakker adds. “Besides, the idea of walking around with an animal translator may seem cool, but many animals might not be interested in chatting.”

“Why would a bat want to speak to you?” she asks. What interests her is what we can learn from how bats and other creatures talk amongst each other.“We should listen to nature and ask the animals’ requirements in order to better protect them,” she argues. For example, a system set up to record whales or elephants can also track their locations. This can help our boats avoid whales or protect elephants from poachers (偷猎者).

Protection is one goal driving Project CETI. “If we understand sperm whales better, we will be better at understanding what’s troubling them,” says Gašper Beguš, a linguist at the University of California, Berkeley. Learning that a species has something very similar to language or culture could also inspire people to work harder to protect it.

When we protect an animal that has some version of language or culture, we’re not simply protecting nature and we’re also saving a way of life. Marine biologist Denise Herzing says that animals are supposed to have a healthy environment so that their cultures can develop well.

9 . Are you a fan of birds? If so, you may have admired their beautiful colors and sweet songs. But do you know these feathered friends can actually do more than that?

A new study published in the journal Scientific Reports finds that exposure to birds, either in the home or outdoors, can boost people’s moods.

Researchers at King’s College London used a smartphone app built by the school’s Urban Mind project to collect the real-time feelings of study participants upon seeing or hearing a bird. A total of 1,292 people living in the United Kingdom, Europe, and the United States participated in the study which was conducted between April 2018 and October 2021.

The app asked participants three times a day whether they could see or hear a bird followed by a series of questions on their mental well-being. Participants were also asked questions about whether they could see trees, plants or hear any water to see if people were experiencing better mental well-being due to being in or seeing nature, and not just because of exposure to birds.

According to the study, the mental well-being of study participants with and without depression was significantly improved after seeing a bird or hearing birdsong compared to not seeing or hearing a bird.

There is a growing number of studies that link spending time outdoors (either in green leafy places or next to bodies of water) to improved mental health. But there are few studies that look at how different aspects of nature can play into humans’ mental well-being.

And while the study adds to the small pile of research on birds and mental health, the report marks the first time researchers have studied the responses to birds and mental well-being in real-time, according to Ryan Hammoud, lead author of the study.

“They kind of examine nature as a single object when nature includes many different characteristics and features like trees, plants, water, birds,” said Hammoud, “We choose to focus on bird life to try and understand which specific characteristics of nature benefit mental well-being.”
