1 . Life beneath the sea surface can be lovely and lively. But many organisms there produce poisonous chemicals to hunters. Divers are now collecting such poisons as drugs for human medicine.
Sharks aren't the scariest things in the ocean for scientists who dive to work. Powerful currents, creating where the ocean floor drops away, can be just as deadly. But the scientists who work underwater are trained to deal with these dangers. The rewards of research and underwater adventures are greater than the risks.
The sea may seem like a strange place to look for new drugs. But organisms in the ocean have had to adapt to a tough environment. The chemicals they make for survival might help people, too. More than 50 years ago, scientists discovered a new anticancer drug in a sea sponge. Since then, researchers have been hunting for more of such useful natural products in the seas.
With the help of underwater robots and small submarines, scientists are searching the seas—from shallow reefs to the ocean's great depths.
Bacteria living in the Arctic's cold waters break down their food using more different ways than organisms on land do. This process of turning food into energy for growth, activities and reproduction is called metabolism (新陈代谢). These pathways also produce chemicals called “secondary metabolites”. One day they also might help people.
During a fouryear project called PharmaSeas, scientists made thousands of extracts from those seafloor samples. In about a dozen of them, researchers found mixtures that can kill bacteria that some of today's antibiotics (抗生素) cannot kill. Three other newfound chemicals reduce epileptic seizures (癫痫病发作) in mice. Yet another compound may reduce the symptoms of Alzheimer's disease.

2 . Traveling to a foreign country can make you frightened if you don't know the local language.Mr.Thibault has a number of tips to help travelers manage in a destination when they don't speak the native tongue, based on his own experience.Here are a few of them.
Download a Language Translation App
Mr.Thibault tends to rely on Google Translate and suggests that travelers find an app that works for them.Ideally, find one that specializes in the language you need to translate especially if the language uses a character set you’re not familiar with, or have difficulty pronouncing.
Speak with Your Hands and Head
Pointing with your hands and nodding or shaking your head, Mr.Thibault said, are easy ways to communicate with locals in the country you’re in.“Gestures are all universally understood，” he said.
Learn a Few Key Words
Knowing basic words and phrases like "hello""thank you” and “I’m sorry，I don’t speak your language.Do you speak English?” is a must, Mr.Thibault said.Showing that you care enough to learn some of the language before you go, and at least enough to acknowledge that you don’t know more, is a form of respect and will make you go a long way to be liked by locals.
Work with a Local Travel Agent
If you feel particularly uncomfortable in the country you’re heading to, and you have to go anyway, relying on a local travel agent who knows both your and your destination's languages can be incredibly useful.
Hire a Local Tour Guide
A tour guide can help you get a better grasp of the local language and is a good person to practice words and phrases with.Whenever Mr.Thibault visits a new country, he books a sightseeing tour with a guide on the first day of his trip.“I use this day to learn about my destination and get familiar with the language,”he said.

The moment you hear the music, you can't help but to move your hips a bit. You feel relaxed and it gives you the energy that you need to have throughout the day." she says.
But Mowry-Housley knows that workouts are only one part of mental health, which is why she encourages people who are truly having problems to seek help not to be afraid to talk about their mental problems. “If you're really struggling, it's okay to talk about it." she says."You are not weak, you are actually strong."

5 . For Stevens Point locals in the US, the city is flooded with delicious fried fish. Here are four top choices for the community to have a try.
Hilltop Pub&Grill
Hilltop Pub&Grill first opened in the 1980s and took the Stevens Point community by storm with its delicious food and unique decoration style. Its fried fish are beloved due to the use of “high-quality North Atlantic fish, with a light beer batter (面糊)”.
The Final Score Bar&Grill
The Final Score Bar&Grill aimed to become a local hot spot in 2001 when Jim Billings, the owner, took charge of the business. Billings feels that their five batter choices set them apart from their neighboring bars. Besides, various wines are available.
Point After Pub&Grill
Point After Pub&Grill started serving delicious food and cold beers in a welcoming environment in 2009. But its history runs much longer. “Before it was Point After Pub&Grill, it had been Northside Bar for 30 plus years,” explained Molski, the owner. Molski feels that the pub’s four special batter choices and other fish specials are what help make it an area landmark.
Two Harps Pub
This Irish pub opened its doors to the public in 2017 and has been drawing fans and locals ever since. “I had done my career for a long time and was kind of bored with it,” said Nick Moore, the owner. “And this opportunity fell into my lap, so I went with it. It really made sense to open up an Irish bar.” The growing pub advises guests to try a cold beer with their Friday fried fish.

7 . To get in shape soon, some people use “quick” methods without realizing that these methods can put their overall health in danger. For example, they lose weight by eating fat-free food. It’s true that consuming（消耗）fewer fats can help you get in shape sooner, but low fat foods like dried fruits, nuts, beans, etc, actually contain high amounts of calories. For example, fruit juice contains no fat, but has high calories, so drinking more than one glass of fruit juice won’t help in losing weight.
To rely only on fruit and vegetable juice to lose weight is also a wrong method. By replacing your meal with only juice, you decrease the calorie intake（卡路里摄取量）greatly. It’ll help lose weight, but it can make you lack energy, leading to headaches, stomach disorders, etc.
It’s true that exercise helps to keep healthy weight, but it’ll probably not help you much if you don’t take care of your diet by reducing your calorie intake. If you believe you can exercise every day and eat as much as you want, you’re incorrect. For healthy weight loss, you need to burn more calories than you consume. So, you need to limit the intake of food.
Wrong weight loss methods are dangerous. So if in doubt, you’d better ask a doctor before starting weight loss. Luckily, it’s possible to lose weight with healthy methods. For example, follow healthy food habits, exercise regularly for 20-30 minutes every day, and go on with a healthy lifestyle even after you lose weight. Anyway, as you don’t gain weight overnight, it can’t be lost in a short time either. Give yourself some time. Although healthy methods may take a bit longer to work, they’re surely good for your body.

8 . Unforgettable Things to Do in Tanzania
Climb Mount Kilimanjaro
Climbing Mount Kilimanjaro is among the most adventurous things to do in Tanzania. It’s a big tourist attraction with around 35,000 visitors attempting the hike each year. However, it’s not overcrowded. And it’s still an adventure to be especially proud of because not everyone makes it all the way. You won’t need any special climbing equipment. Just bring proper clothing, food, water, and an adventurous attitude.
Get a Taste of Local Urban Life in Arusha
In Arusha, you can experience what city life is like in the country. The city sits at the foothills of Mount Meru, surrounded by large fields of corn, beans, coffee, and wheat. You can buy cheap, fresh local produce in markets throughout the town. The cultural center hosts African art and culture exhibits. It’s good place to purchase a souvenir or two.
Visit Some Prehistoric (史前的) Sites
The great rift (裂缝) valley runs all the way from Lebanon to Mozambique. This rift is where human life is believed to have begun. At Isimila Gorge, you can look at stone age tools from almost 100,000 years ago. There’s also a collection of fossils of extinct animals. This find, dating back3 million years, helps us to learn how humans evolved (进化) in Africa.
Watch Beautiful Birds by Lake Manyara
Lake Manyara is not only a beautiful piece of nature. It’s also home to about 300 species of migratory birds. You can find various eagles, storks, and kingfishers. But what makes this lake most famous is the pink flamingo (火烈鸟) population. You can find thousands of flamingos here. It’s a big attraction for bird watchers and photographers.

9 . Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
“I think we are knocking at the door of immortality(永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “I think by 2075 we will see it and that’s a conservative estimate(保守的估计).”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what was possible in the past. “There is a great effort so that people can live from 120 to 180 years,” he said. “Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. “It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Centre. “At present people who could get to that point are not in good health at all.”
