【推荐1】A gym membership can be nice.     1     All you need is a little bit of time and space at home for yourself. But before everything, you need to create an at-home fitness routine.

Spend 5 to 10 minutes warming up before every workout. Not sure what to do? Try jumping jacks, leg or arm circles, or even dancing. Just get your blood pumping. Do a progressive aerobic (有氧的) activity that uses the same muscles you want to work out.     2    

Do strength training twice a week to build muscles. Strength training, also called resistance training, makes you stronger and builds endurance (忍耐力).     3     This helps you do a harder workout every time you exercise.

    4     You might be eager to just stop your workout when you’ve finished your last set of activity, but take a few minutes to do low-intensity exercises that lower your heart rate. You might drop your run into a walk or slow down your cycling, for instance.

Set achievable goals that you can break into smaller tasks. It’s one thing to say you want to get fit, but that means something different for everyone.     5     It should be specific, realistic, and meaningful. Then, break down the goal into small, actionable steps so it feels like you’re making progress regularly.

【推荐3】The rules of surfing the Internet

Do you obey the rules while surfing the Internet?

Your Security Is Your Problem

You know there are signs in every parking garage saying they're not responsible for lost or stolen items in your vehicle.     1    

You're Speaking in n Public Forum(论坛)

Everything you post online is equal to posting it on the front page of the newspaper and delivering it to everyone around you. Some people may agree, and some may disagree. You may even strike a chord(引起共鸣)with enough people to start a movement.     2    Only say online what you're willing to say in front of your grandma.

    3    

The content of your posts matters, but so does where you're posting. The audience of a particular website may not agree with your particular message (or at least with the way you're presenting it), so be careful where you post.

Keep It Civil

Freedom of speech is important---everyone should have the right to say what they want, and a few people who abuse this freedom can't affect anyone.     4    This doesn't mean there aren't consequences to your words, however, so do with caution. Put forth the effort to be polite whether online or off.

You Should Be Anonymous

Anonymity(匿名)sounds like what some crazy hacker groups fill, but it's not.     5    The reason why we all support Anonymity is that we believe every human being deserves the basic human right of being anonymous. You should be anonymous too.

【推荐1】Since 2001, robotic tools have revolutionized the practice of surgery. They have greatly reduced the stress and physical demands normally placed on surgeons and have made certain procedures possible.

One example is “keyhole surgery”, or minimally invasive (微创) surgery, which normally requires surgeons to stand at awkward angles and make difficult movements with their hands to make a cut inside the patient. But in June 2022, surgeon James Ansell used 3D glasses and two sticks to control four robotic arms to perform a procedure to remove a cancerous tumor. “My colleague said... that this feels like cheating,” Ansell said to The Guardian.

Another area of surgery that has had major technological breakthroughs in recent years is telesurgery. Normally, telesurgery relies on a wired connection due to concerns of harming the patient should a wireless connection drop during surgery, but China made several advancements in wireless telesurgery based on 5G technology.

China achieved the first 5G-based remote operation in March 2019 involving a brain surgery procedure between a surgeon in Sanya and a patient in Beijing, a distance totaling nearly 3,000 kilometers. More recently, a team of surgeons successfully completed remote micron-level eye surgery on rabbits located in a different city. The rabbits were at the Sun Yat-sen University in Guangzhbù, Guangdon g province, whereas the surgical team who operated on them via a 5G robot were at the Hainan Eye Hospital in Haikou, Hainan province.

Looking to the future, people hope that remote surgery could become commonplace to help heal injured soldiers on the battlefield while keeping surgeons at a safe distance. Some even believe that robotic systems, combined with AI, could one day exceed human surgeons.

But, given current technological limitations and the high costs of these robots which can cost millions of dollars, the complete robot takeover of surgery may still be a while off.

A study conducted in Youngstown, Ohio, for example, discovered that greener areas of the city experienced less crime. In another, employees were shown to be 15% more productive when their workplaces were decorated with houseplants.

The engineers at the Massachusetts Institute of Technology (MIT) have taken it a step further — changing the actual composition of plants in order to get them to perform diverse, even unusual functions. These include plants that have sensors printed onto their leaves to show when they’re short of water and a plant that can detect harmful chemicals in groundwater. “We’re thinking about how we can engineer plants to replace functions of the things that we use every day,” explained Michael Strano, a professor of chemical engineering at MIT.

One of his latest projects has been to make plants glow (发光) in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light, about one-thousandth of the amount needed to read by, is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn trees into self-powered street lamps.

In the future, the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off “switch” where the glow would fade when exposed to daylight.

Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source (电源) — such as the distance from a power plant to street lamps on a remote highway — a lot of energy is lost during transmission (传输). Glowing plants could reduce this distance and therefore help save energy.
