Visiting Joshua Tree National Park, California

    Joshua Tree National Park is nearly 800,000 acres (英亩) large and surrounds parts of the Mojave and Colorado Deserts in South-central California. Although deserted at first sight, the park is full of wildlife and provides a variety of entertainment activities from hiking to climbing. Within a three-hour drive, Joshua Tree National Park takes at least a full day to visit.

Things to do

    Hiking opportunities within the park include several choices, from 12 self-guided nature routines to all-day back-country hikes.

    Joshua Tree NP has nine camping grounds, and back-country camping is also allowed.

    Rock climbing is a popular activity in the park, which has 10 mountains greater than 5, 000 feet in height.

When to visit

    Joshua Tree NP is open 365 days a year, although the best time to visit is October through April, when temperature is milder. The peak season is when the wild flowers bloom, and the summer months are the least crowded.

What to bring

    In addition to your camera and telescope, be sure to carry lots of water. Park and guiding maps can be picked up at any of the three visitor centers.

    "Hope has proved a powerful predictor of outcome in every study we've done so far," said Dr. Snyder, a psychologist.

    In research with 3,920 college students, Dr. Snyder found that the level of hope among freshmen at the beginning of their first term was a more accurate predictor of their college grades than were their S.A.T. scores or their grade point averages in high school. "Students with high hope set themselves higher goals and know how to work to attain them," Dr. Snyder said. "When you compare students with equal learning ability and past school achievements, what sets them apart is hope."

    In seeking a way to assess hope scientifically, Dr. Snyder went beyond the usual belief that hope is merely the sense that everything will turn out all right. "This idea is not concrete enough; it fails to clarify two key components of hope," Dr. Snyder said.

    "Having hope means believing you have both the will and the way to accomplish your goals, whatever they may be."

    Despite the wisdom in the old saying "where there's a will there's a way," Dr. Snyder has found that the two are not necessarily connected. In a study of people from 18 to 70 years old, Dr. Snyder discovered: only about 40% of people are hopeful in the technical sense of believing they typically have the energy and means to accomplish their goals; about 20% of the people believed in their ability to find the means to attain their goals, but said they had little will to do so; another 20% have the opposite pattern, saying they had the energy to motivate themselves but little confidence that they would find the means; the rest had little hope at all, reporting that they typically had neither the will nor the way.

    "It's not enough just to have the wish for something," said Dr. Snyder. "You need the means, too. On the other hand, all the skills to solve a problem won't help without the willpower to do it."

    The new president of Harvard University is the son of an Eastern European refugee and Auschwitz (奥斯威辛) survivor—Lawrence S. Bacow. His father worked full time while attending a state college in Detroit at night to earn his degree.

    Bacow, the former president of Tufts University, has taken over Harvard at a time when higher education is under attack for being financially out of reach to many Americans. But Bacow said his family's journey had reflected the power of college education to transform generations and the opportunities that have historically been available in the United States.

    "My parents came to this country with almost nothing," Bacow said. "I wouldn't be here if this country had not been open to people like my parents at that time. Nor would I if my father hadn't had the opportunity to get the college education."

    Bacow grew up in Pontiac, Michigan. His father's family fled anti-Jewish (反犹太的) violence in Minsk, then part of the Soviet Union, before the start of World War II and went to the United States. His mother arrived in Brooklyn at age 19, having survived Auschwitz concentration camp. She was the only Jew from her town to have survived the war. Yet Bacow, who is married with two sons, said that while growing up in Michigan, he had a happy childhood, entering science fairs as a child and building radios like his dad.

    Bacow has spent most of his professional career at MIT, Harvard and Tufts. He was a professor of environmental studies at MIT, and later a principal at the university. He led Tufts from 2001 to 2011. At Tufts, Bacow earned a reputation for shaking up a sleepy university that was being overshadowed by its peers in Boston. He is also credited with leading it through both 9/11 and the 2008 financial crisis.

    As the Tufts president, Bacow traveled around the country, reaching out to alumni (校友), and he urged his faculty and deans to do the same, in an effort to boost donations to finance Tufts' academic ambitions. He raised more than $20 million for faculty recruitment, attracting up-and-coming professors by offering junior faculty perks (福利), such as long academic leaves that they couldn't get elsewhere.

    Under Bacow's leadership, Tufts spent millions on labs and libraries. He also made addresses nationally about the need to make higher education more accessible and affordable to low-income students.

    A hospital has been forced to ban Pokemon Go players from the site after a monster hub(妖怪枢纽站) was found in the A&E department. Royal Stoke University Hospital discovered that its casualty unit(急诊室) is on the same spot as a Pokemon Go 'gym' ­­ where players can train their newly caught Nintendo creatures.

    The University Hospitals of North Midlands Trust agreed last week that patients can play Pokemon Go on wards because walking around is healthy. But the Trust has been forced to post a warning on its website about public access to A&E. It said if Pokemon Go becomes a major annoyance it would ask Nintendo­­ which decides on the locations of the virtual gyms according to GPS­­to have it removed from the premises(道馆).

    Kevin Parker, associate chief nurse, said, "Members of the public who do not need to be at Royal Stoke should not attempt to enter A&E or any other part of the hospital building to play the game. The A&E department is incredibly busy this summer. We want the public to understand that anybody who visits the hospital solely to play the game will provide an unwanted distraction to the important work of the hospital. I'm also aware of various reports in the media of unsafe areas that the game has been played in."

    "Royal Stoke University Hospital is a safe area where gamers can enjoy Pokemon Go." Michelle Harris, the Trust's manager, said the game could still be played by those already in hospital. "We recognize that the Pokemon Go game encourages walking and exercise, which is something that the Trust is equally keen to promote," she said.

    There are a number of "walking routes" established throughout the Trust that can be used to combine walking and playing the game. "Walking just 30 minutes, five times a week, can help reduce the risk of preventable illnesses such as obesity, diabetes, and heart disease."

    There have been several warnings about the game since its UK release. Last week a group of teenagers in Wiltshire were left stranded almost 100ft underground after they got carried away searching for Pokemon Go characters. The four boys, aged 16 and 17, ended up getting lost and had to wait to get a phone signal before they could call for help. Eventually, they contacted Dorset and Wiltshire Fire and Rescue team, who took them to safety. Damien Bence, of the fire and rescue team, said: "Pokemon Go is obviously leading people into dangerous situations."

Researchers at MT created a high-tech pill that starts to vibrate(震动) once it makes contact with liquid in the user's stomach and make him or her feel full. The pill was reportedly thought up by Shriya Srinivasan, currently an assistant professor of bioengineering at Harvard University.

VIBES, short for Vibrating Ingestible BioElectronic Stimulator，was only recently made public in a study published in the Science Journal, but it is already being announced by the media as the future of weight loss. Although it has yet to be tested on humans, trials on pigs have achieved very hopeful results. After about 30 minutes of VIBES activity, pigs consumed on average almost 40 percent less food in the next half hour than they did without the smart pill. Apparently, the revolutionary device works by activating stretch receptors in the stomach, modeling the presence of food. This in turn signals the hypothalamus(下丘脑) to increase the levels of hormones that make us feel full. The vibrating stimulator, which is about the size of a vitamin pill, is powered by an encased battery and activated either by the gastric fluid(胃液) breaking down a coat around the pill, or by an incorporated timer. After producing the desired effect, the pill exits the body with other solid waste.

The good news is that it is expected to have a cost in the cents to one dollar range, and researchers say that it may eventually be possible to implant the stimulator and thus remove the need for people to constantly swallow it.

"Our study demonstrates the effectiveness of a low-cost, non-operative intervention to reduce food intake and calorie consumption. The device functions effectively in the stomach and leading to fullness," said Giovanni Traverso, co-author of the study. "The device has the potential to revolutionize options for weight loss treatment. However, future studies will need to explore the physiological effects of the device before it's available for patients."

Researchers are now exploring ways to scale up the producing of VIBES capsules which could enable clinical trials in humans.
