If you're encouraged by the tiny house movement and think 160 square feet is just enough for your needs, you may want to contact the Academy of Construction and Design (ACAD) at IDEA Public Charter School in northeast Washington.

    Students in the program built a micro house with a kitchen, a bathroom, a sleeping loft with space for a queen-size bed and a storage loft, all set on a trailer for mobility. The exterior of the house was part of a continuous living exhibit in 2015 and was moved to the IDEA campus so students could work with builders to complete the interior earlier this year.

    McMahon said the D. C. government's approval to push companies to hire District residents was at odds with the school system not preparing students for careers in construction, exploring or electrical work. McMahon gathered industry and community leaders to establish ACAD in 2005, and he said 100 percent of the companies he contacted responded positively to the idea, including major firms such as JBG, Clark Construction, Hines Construction and Boston Properties.

    “When students make the connection between what they are learning a potential career, their academics improve dramatically,” said Carol Randolph, chief operating officer of the D. C. Students Construction Trades Foundation. “Some of them who didn't think college was an option now have a better chance because their classes have become relevant to a job.”

    “We teach them life skills and explain that even if you start as a laborer, there are opportunities to move up quickly,” he said. “We rewrite the story for them and explain that they can work for a few years, make good money, get promoted, and start their own business or go to school with less debts.”

    “Parents and school advisor can be the biggest obstacles because of the negative idea of construction as a blue-collar career,” Karriem said. “I get middle-school advisor on board to talk about the opportunities this education provides. These kids are learning lifelong skills that can help them in other fields, provide them with income and allow them to take care of their homes.”

    What is it?

    KindSpring has created a series of 21-Day Challenges designed to help individuals and groups grow in values that help create positive change. Regardless of profession, age, culture or geography, when we try to cultivate(培养) certain values we create a ripple effect(连锁反应) that has the power to transform our lives and the world for the better. When we practice these values together over and over again, our efforts encourage and strengthen each other in remarkable ways. Each of our 21-Day Challenges focuses on a specific value — from kindness to mindfulness. Click here for more information.

    How does it work?

    A small daily commitment + a daily prompt(提示)+ a process for communication. Each 21-Day Challenge invites participants to carry out one small daily action related to the main theme. Every day for three weeks a unique idea is emailed out that serves as a prompt. Participants are encouraged to carry out the act and share stories of their experiences in both online and offline spaces. You can sign up to participate as an individual or you can “host” a challenge for a group you belong to. The challenges were developed for workplace, school/college and family environments, but are broadly usable. Any group is more than welcome to take them on. At the end of 21 days, you may continue the practice with your group, take on a new challenge, or even design your own. There is no charge for any of our services. All the challenges are offered as a gift. Five steps to host a challenge.

    Why should we do it?

    The 21-Day Challenges are all designed to fit the pace of modern day life. They are not very time-consuming（耗时的）, and in most cases demand less than five minutes a day. Twenty-one days certainly can't change everything, but it can begin a new way of being. You are invited to bring these practices to your company, school, community center, or family. Get started with joining a challenge or hosting one here. Let us know if you have questions—we're delighted to help any way we can!

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.
