In the future，therapy patients may spend less time sitting in a therapist's office and more time exploring virtual worlds.Researchers have created a new virtual reality（VR）app to treat the fear of heights.The app just had a clinical trial.
People developed other VR therapies in the past.These programs needed a real-life therapist to guide patients through the treatment.But the new system only uses an animated avatar（虛擬化身）within the app.The avatar coaches patients as they climb a virtual high-rise.This kind of therapist-free counseling could make it much easier for people to get help for fears and other disorders.
This is "a huge step forward" for VR therapy，says Jennifer Hames，a clinical psychologist."With this system，people don't need to visit a therapist's office to get expert help.They could get help in their regular doctor's office，or even at home.That could be good for people who aren't comfortable with face-to-face therapy，or who can't afford it，" she says.
To test how effective their app was，F(xiàn)reeman and colleagues recruited（招募）100 adult volunteers，who were moderately to severely afraid of heights.The researchers randomly assigned 49 people to have VR treatment while the other 51 participants got no treatment.Before the experiment began，participants filled out a questionnaire that rated their fear of heights from 16 to 80.They filled out the same questionnaire right after the treatment.Then they did it again two weeks later.
The scores of patients who got no treatment stayed the same.But people who used the VR app dropped an average of about 25 points on the scale."The results give strong evidence that the new VR program is more helpful than no treatment at all.But it's not clear how well this type of system could work for more complex mental health issues，" says Mark Hayward，a clinical psychologist at the University of Sussex."And when it comes to helping people with more severe symptoms，VR probably won't replace trained therapists any time soon."

1．Each year on Halloween，children look forward to trick-or-treating （不請(qǐng)客就搗亂） for candies．But for some kids，eating Halloween candies can be dangerous．
That's because one out of every 13 kids in the Us have a food allergy（過(guò)敏癥）．They are allergic to ingredients（成分）in many Halloween candies，such as peanuts，tree nuts，milk，eggs，and beans．If they eat these foods，they will get sick or even die．
"I had to throw away all my candies with tears，" eight-year-old Conlen said．Conlen is allergic to peanuts，tree nuts，and dairy．Twelve-year-old Kylie is allergic to peanuts and tree nuts．She has been trick-or-treating only twice． "I brought my candies home and gave them to the neighbors，" Kylie said． "It felt terrible．"
But this year，Conlen，Kylie and other kids with food allergies will have a chance for a happy Halloween．That's because nearly 100，000 households across the US have promised to take part in the Teal Pumpkin Project（TPP），which was started last year by Food Allergy Research & Education（FARE）．FARE is an organization that works to improve the lives of people with food allergies．Through the project，the households agree to have nonfood items for trick-or-treaters，including trinkets（小飾品） and toys．
To take part in the project，people buy a teal（藍(lán)綠色） pumpkin or paint a pumpkin teal and place it in front of their house．The painted pumpkins let trick-or-treaters know that nonfood items are available there．The households also add their home addresses to an online map，making it easier for trick-or-treaters to find them．
Kylie loves the idea．"The TPP makes Halloween fun and safe，" she said．"It makes me feel like a normal kid，and it makes everyone feel included．"

3．Besides the excitement of travel，one reason to study abroad is that you will experience new customs，holidays，foods，art，music，and politics first-hand.
"I learned the language and am now fluent，but perhaps what's more important is how much I learned about cultures，people，and myself.I learned this from the viewpoint of an active member of the community and my host family，not from the tourist's point of view，" says Andrew，who studied in Poitiers，F(xiàn)rance.
Another reason for studying abroad is that you'll gain self-confidence.Christina studied in Caracas，Venezuela，a city of more than 3 million people and a huge change from her hometown of 35，000!Christina says she learned how to better stand up for herself and her beliefs and to express herself in another language.What could make you more confident than that？
Living away from home can also help you adjust in the transition（過(guò)渡）to college and adulthood.Mathew says he returned from studying in Australia with confidence and a real interest in international affairs that made him different from his peers（同齡人）. "After having gone abroad in high school，I found the transition to college a breeze—moving 560 miles from home didn't seem particularly frightening after having lived thousands of miles away."
Most of all，it's fun while you're studying in a different learning environment.
