Bandhavgarh National Park in India is best known for its amazing setting, as well as having the highest concentration of tigers in India. In addition to tigers, there are also bears, deer, wolves, birds, etc.

    Location: In Madhya Pradesh state, almost 200 kilometers northeast of Jabalpur. The nearest village is Tala, which is the access point of the park.

    Opening Hours and Safari (游猎) Times

    Safaris operate twice a day, starting at dawn until late morning, and mid afternoon until sunset. The best time to visit the park is early in the morning or after 7 p.m. to spot the animals. The park is closed from July 1 to September 30 due to the monsoon season (季风季节).

    Bandhavgarh Zones

    Bandhavgarh is divided into three main zones: Tala (the park's best zone, with the most tigers), Magdhi (the second best zone to see tigers), and Khitauli (scenic and less visited, although tiger sightings do occur there; particularly good for birding).

    Entry Fees and Charges for Jeep Safaris

    Bandhavgarh has become expensive to visit in recent years. Entry fees have increased since October 2014. When going on a safari, separate fees must be paid for park entry and jeep hire. Entry tickets are priced per vehicle (up to six people). For 2015-16, park entry tickets cost as follows:

    ·Tala Zone: 2,400 rupees for Indians, 4,800 rupees for foreigners. (Up to six people)

    ·Other Zones: 1,200 rupees for Indians, 2,400 rupees for foreigners. (Up to six people)

Jeep Hire

    Expect to pay about 2,200 rupees to hire a jeep, in addition to the entry cost. This can be done at the park entrance. All hotels can arrange jeep hire and tours, but at a higher rate. It's much less trouble though. Besides, unlike many national parks in India, it's possible to take private vehicles into Bandhavgarh.

    Research finds out why some people are constantly under attack from the bloodsucking insects while others walk free.

    For those unfortunate enough to feature highly on the mosquito hit list, summer nights can be synonymous with mosquito bites. Yet others hardly ever get bitten. So how do the bloodthirsty insects select their victims?

    The insects' tastes may seem arbitrary. However, research shows that when mosquitoes make their choices between potential victims, it all comes down to scent (气味).

    “Mosquitoes are attracted by carbon dioxide and heat, which everyone gives off. But mosquitoes are also attracted by certain scents,” says Karl-Martin Vagn Jensen, the head of research at the Department of Agricultural Science at Arhus University.

    According to Jensen, it has not yet been confirmed exactly what the scents in question are. But research does indicate that some scents are more attractive to mosquitoes than others.

    “All the lab employees rubbed petri dishes (培养皿) against their stomachs. In that way, their scents were put on the dishes, which were then put in a container full of mosquitoes,” he says. “The mosquitoes repeatedly landed on some of the petri dishes, but didn't go anywhere near the others.”

    Perhaps taking inspiration from popular fiction, there are also those who consider garlic as an excellent repellent (驱虫剂) against the winged bloodsuckers. According to the researcher, this strategy may not be entirely fruitless. “As far as I know, there is no scientific proof that eating garlic works. But there may be something to the theory that it's possible to mask scent with garlic,” he says. The only reliable method of protection against mosquitoes is to use repellents that are sold over the counter. It contains some smells that can confuse the mosquitoes. When the mosquito comes closer, it uses smell, heat and carbon dioxide to decide whether to bite. But if it is confused by a repellent, it will never get that far.

    Feifei, an 11-year-old boy from Xuzhou, Jiangsu Province, suffered from a sudden acute eye disease which has almost led to blindness. The disease was caused by excessive（过度的）eye fatigue（疲劳）during the winter vacation, during which he played computer games for continuous 10 days and nights.

    Many youngsters in China nowadays are increasingly addicted to computer games and other electronic products. This is followed by a series of health problems, with the most typical case being myopia, or nearsightedness.

    According to the latest research report released by the World Health Organization (WHO),the myopia rate among Chinese teenagers ranks first in the world—70 percent of high school and college students. The rate is nearly 40 percent in primary school students, while it is only 10 percent for their peers in the United States.

    There are at least 10 million people in China with severe myopia, and they are likely to get pathological（病理性的）myopia in middle age. Pathological myopia can't be treated with glasses or surgery, and it is one of the biggest factors that lead to blindness, Xu Xun, director of the ophthalmology（眼科学）department at Shanghai General Hospital, pointed out.

    Experts explain that two major factors lead to the high rate of myopia among Chinese people. One is high academic pressure, and the other one is excessive use of electronic devices over a long period of time .Genetics, on the other hand, are not the main reason, as only 20 percent of Chinese people had myopia in the 1960s.

    "Teenagers are now faced with severe academic pressure, which means they often study without natural light. This increases their risk of becoming nearsighted," Xu said.

    Experts suggest that youngsters maintain a proper balance between study and rest so as to protect their eyesight, and parents should play an active role in the process.

    During this shopping season, salesmen will come up with different strategies to get your business. Many product companies use specific colors to cause positive emotions and compete for a sale. However, sight is not the only sensory (感官的) retail that companies use. Sounds and smells can also influence consumers' purchasing decisions.

    Nobel Prize-winning research shows that our sense of smell has great power to cause an emotional response. A study published earlier this year compared purchasing in a French flower shop when the smell of lavender (薰衣草) was given off and when it wasn't. It found that the smell increased the number of consumers' purchasing items and the amount of their purchases. An earlier study using Nike shoes found that consumers desired the shoes more, and were willing to pay more, when the room had a mixed smell of flowers. Realizing the subconscious impact of smell, many stores apply artificial scents (气味) through their heating and air-conditioning vents (通风口) or place scent machines above their doors. For instance, a coconut scent might make that bikini more appealing as you long for a vacation.

    Ever felt frenzied due to a store's fast-paced music? Or calmed by a piece of light music? A retailer's choice of music can have a big impact on consumers' moods. One study found that when subjected to loud music, consumers will spend less time in a store. But interestingly, the researchers did not find a difference in sales or customers' satisfaction. Another interesting finding from a recent study was that customers actually shop longer when exposed to unfamiliar music. Just as department stores use different scents in certain departments, many use different music in some areas to appeal to varying consumers.

    Well, you could always leave the store and take a break, but the food court probably isn't your best choices as brands like Cinnabon and Panera Bread also use scents as part of their customers' experience. Online retailers (零售商) use a variety of other strategies to get your business, but you can always neglect those and enjoy the familiar scents of home.

    According to a recent study, a new genetically modified rice can prevent infections of HIV, the virus responsible for the disease AIDS.

    The study reports the newly-developed rice produces proteins that attach directly to the HIV virus. This process prevents the virus from mixing with human cells. The scientists say it can remove the effect of the virus and block its spreading.

    The Joint United Nations Program on HIV/AIDS reports that worldwide, nearly 37 million people were living with HIV in 2017. The organization says the largest number of those are in developing countries. Nearly two-thirds of HIV cases are in Africa. Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease.

    The new study predicts the rice-based method will lead to long-term use of the anti-HIV treatment across the developing world. Researchers said the "groundbreaking" discovery is "realistically the only way" that anti-HIV combination treatments can be produced at a cost low enough for the developing world.

    They say the easiest and most cost-effective way to use the rice will be to make it into a cream to be put on the skin. The HIV-fighting proteins can then enter the body through the skin. People all over the world could grow the rice and make the cream themselves. This would prevent the cost and travel required for many patients to receive treatments and medicine.

    The process of changing the genetic structure of food crops has been debated for some time. Critics of genetically engineered crops believe they can harm people. The scientific team says further testing is needed to ensure that the genetic engineering process does not produce any additional chemicals that could be dangerous to people.

    Apple and Microsoft each launched new products. One company astonished everyone. The other made people sleepy. Can you guess which was which? You probably guessed wrong. Because Apple, famous for its creative products, was the tech giant whose new product caused a collective shrug. While Microsoft, which stole a move out of the Apple Playbook, won cheers from high-end, creative-class consumers like business analysts, media designers and music producers.

    As Hayley Tsukayama remarked at The Washington Post, the Surface Studio, one of Microsoft's new products, is really just a super-sized version of the Surface Books product that Microsoft has been selling for years. But if you've ever watched science fiction movies like Minority Report-- where Tom Cruise seems to operate pictures and data hanging on mid-air by touching them, spreading his fingers to increase on details, and sending files and information sliding from one folder to another with a click of the finger, you can see how Microsoft is trying to show the same experience.

    Meanwhile, apple's new products were almost like some fine promotions for its Apple TV. They boast that the new Macbook Pro has a smaller size and more functions, and a new touch screen bar on laptop keyboards where function keys used to be.

    So what's going on? In many ways, Apple is focusing on attracting the average consumers who have been attracted by Microsoft. And Microsoft is focusing on targeting the high-end professionals Apple has historically been associated with. You can even see this is the companies' ad campaigns: Microsoft's ads stress imagination and creativity, while Apple's commercial chief performance and convenience of its Macbooks.

    So Apple is trying to control the world of devices and laptops from the top down, starting with the high-end market and moving on to appeal to a broader base of consumers. Microsoft, having already strengthened itself within the bigger low-end market, is now attempting the opposite with a bottom-up strategy. Will they succeed? Time will tell...
