1 . When you have to cancel your Thanksgiving plans due to the spread of the COVID-19, you may find yourself craving companionship as much as that pumpkin pie. That’s because parts of the brain respond to loneliness much like they react to hunger, according to a study in Nature Neuroscience.
Researchers from the Massachusetts Institute of Technology scanned the brains of 40 healthy, social young adults after 10 hours of either fasting (禁食) or social isolation (隔离). They found that after being alone, participants’ neurological responses to social signals were similar to hungry people reacting to food — that is, certain areas of the brain linked to desire were turned on to start working.
For an isolated person, a picture of people laughing together caused the same areas of the brain to light up as when a hungry person looked at a big plate of pasta.
“Just like hunger is an unpleasant sensation that motivates us to seek out food and thirst motivates us to seek out water, loneliness is a biological need that motivates us to reconnect to others,” Holt-Lunstad told Insider.
Researchers were surprised to find that people who were prevented from socializing became much more focused on that need, and less reactive to hunger. As their loneliness increased, they became less responsive to images of food.
These latest findings suggest that the relationship between food and loneliness might be more complicated than we thought, despite the popular opinion of stress-eating to cope with social isolation. More research is needed to understand the complex ways people deal with loneliness.
Studies like this can help scientists understand how the brain processes loneliness, and possibly reduce the negative consequences. However, although loneliness may be similar to hunger, fixing it isn’t as easy as serving someone a hearty dinner because people are unique and they need varying levels of social interactions to meet their needs.

2 . Four best scenic paths near London
Goring Gap and the Thames PathLength: 5 miles
Start: Goring & Streatley station
End: Pangbourne
This path is far from boring for a rural walk. The footpath follows the curve of the river as it flows south, winding past wildflower grassland, and the Hartslock Nature Reserve, which is home to red kites and rare orchids.
Post-walk pub: The Swan serves these days. Order a table or keep warm by one of its open fires.
Box HillLength: 6.8 miles
Start and end: Westhumble station
Admire the glorious views and escape the crowds. But first you’ve got to climb 272 steps to the top of Box Hill. The endorphins are definitely pumping—maybe that’s how it got the nickname “Happy Valley”.
Post-walk pub: The spacious Tree on Box Hill has an enticing menu and huge beer garden.
The Kentish CoastLength: 9.8 miles
Start: Ramsgate
End: Margate
Following the path, you’ll pass plenty of former smugglers’ (走私者) caves and there are beachside cafes dotted along the route at regular intervals.
Post-walk pub: Order a pint of beer at Xylo, a pub with wonderful views over Margate Sands.
Chess Valley in the ChilternsLength: 9.9 miles
Start: Chorleywood station
End: Chesham station
It isn’t home to any chess masters, but it did used to produce n lot of watercress, fed by its sparkling chalk stream. This walk follows the river, whose bank is covered with the rolling grass and woods.
Post-walk pub: The George & Dragon is an old coaching inn with a log fire and real beer.

3 . Imagine a school where students are taught by the best teachers in every subject, regardless of location. Imagine a school where students could go on safe field trips to the Amazon rainforest or Everest base camp. Well, such schools are already being built: in virtual(虚拟的)reality.
Last year, Optima Academy Online, an all-virtual school, delivered courses that aim to improve the hearts and train the minds of young people. These courses are of different levels, attracting 170 full-time students from all over Florida. In the progress of home-schooling, students use headsets for about three hours a day for formal lessons and then do course work independently with digital check-ins.
Future versions(版本)of VR will doubtless be widely used in education, but the only questions are: for what purpose and at what speed? There are enough reasons to doubt whether VR schools represent the future of education. Sticking a child in their bedroom with a heavy VR headset fastened to their face and no physical social interaction with other kids will fill many of them and their parents with horror.
A recent report concluded that digital education could significantly improve the quality and equality of schooling systems. But if managed poorly, it could have the opposite effect, turning a digital divide into an educational one. There is growing evidence to suggest that is happening. In Mexico, only 24 percent of 15-year-old students in poor schools have access(使用)to a home computer for schoolwork compared with 87 percent in rich ones.
Used properly, technology can be great for enabling self-motivated students to access learning resources and connect with fellow students and teachers all over the world, says Beeban Kidron, a member of the UK’s Digital Futures Commission. The trouble is that Edtech is too often seen as a shiny new toy that will solve all problems and save money rather than being viewed as a different way to learn, she adds.

4 . A therapy (治疗) client and I are working on an eating disorder and find it originated from a relationship break-up or perhaps being bullied in middle school. Such hurtful experiences led to not eating for a couple of weeks. Then comes a high praise from a friend that totally backfires. Maybe it’s an enthusiastic, “Wow, you look great!’’ In a flash, this praise excites an inner and often unconscious thought: “Oh, people care more about me if I lose weight. So many things feel out of control but I can control people’s affection by not eating.”
Often, very well-intentioned individuals offer praise out of a desire to uplift and connect. Such praise is often tied, directly or indirectly, to a person’s relationship with the standards of a specific group or institution. Sadly, such praise can easily reduce an individual’s dignity to their level in line with the group’s expectations rather than supporting their inherent (固有的) dignity and worth. So, what’s a better way?
One answer is to exit the game of “right and wrong” and enter a more life-giving focus on what needs are present. Returning to our example above, when you see that someone has lost weight and you want to give them a praise, just pause and take a deep breath. Simply ask, “How are you doing?” See them and hear them. Appreciate them as a person of limitless value. Know there may be much more to their inner world than meets the eye. Similarly, when you see someone’s success in school, appreciate the hard work they put into it. Ask with gentle curiosity, “How’s it been for you?” Listen with your full attention that in itself can be a rare gift in today’s hustle and bustle world.
By maintaining your concern and listening to the ways they want to be accompanied and supported — even when it might not be your first instinct — you can see them as a whole person, with complex feelings, very human needs, and inherent dignity.

7 . Have you ever imagined an insect-inspired robot, which weighs less than a gram, could one day help out in surgery (外科手术)?
Scientists have designed this small, “insect-bot” called mCLARI that can control and even change its body shape as it travels in different environments to fit through gaps. It’s 2 centimeters long, weighs less than 0.97 grams and can travel at a speed of 6 centimeters per second.It’s the smaller, faster replacement to CLARI, which was designed by the same team.
“Because of the robot’s small size and ability to change shape, we expect usage of this technology in four important areas,” the lead author Kaushik Jayaram said. These include disaster (灾害) response , check on high-value objects, environmental monitoring and medical treatment.
“In the long term, we hope such robots will be used more widely in moving through human bodies and performing surgeries that can’t be easily done at present,” Jayaram said. With mCLARI, Jayaram’s team is moving closer to creating robots that can fit in different environments—just like the insects they’re inspired by.
The mCLARI robot has four legs and can move in narrow spaces by changing between running forward and side-to-side and can use different speeds in human bodies. Its legs are joined to its body through joints (关节), which enables mCLARI to change its body shape based on the environment it is in. For example, its legs can be lengthened up to 50% in certain spaces.
As follow-up work, the scientists want to give mCLARI more power and sensing ability while helping the surgeries. “We are also excited about understanding the effect of shape change on improving functions of robots,” Jayaram said. “And this is sure a great one-step forward of the technology. The robot will have entered the market by 2025 and will bring greater benefits to mankind, especially in medical treatment.”

8 . A man with Parkinson’s（帕金森）disease has experienced a substantial improvement in his ability to walk after being fitted with a device that electrically stimulates his spinal cord（脊髓）. The findings, although based on one person, suggest this could be used to treat movement disorders.
Treatments for Parkinson’s disease include drugs that target parts of the brain which regulates movement, as well as deep-brain stimulation, which changes the electrical signals that cause symptoms. However, many people don’t respond to these treatments, particularly if their condition is advanced, says Courtine.
He and his colleagues wanted to find out whether directly stimulating the spinal cord in a person with severe Parkinson’s disease could help. The team designed the device that specifically targets neurons（神经元）in the spine that are activated when legs walk, which showed promise in non-human primates with Parkinson’s-like symptoms. To test it in a person, the researchers recruited a 62-year-old man called Marc, who has experienced Parkinson’s symptoms for around 30 years. These included pace freezing-sudden and temporary inability to move.
The researchers first had to map the neurons in Marc’s spine. This helped to guide the application of stimulators so they would only target his legs’ neurons. They then placed sensors on Marc’s legs and shoes to monitor the electrical activity of the neurons that activate the muscles in these limbs and his feet. When these sensors detected this electrical activity, they activated the stimulators.
After three months’ training using the stimulators, Marc more or less stopped experiencing pace freezing. Marc says that passing through narrow paths or turning had previously caused pace freezing, which led to him falling five or six times a day. Marc has now been using the stimulator for two years and says he hardly falls any more, allowing him to walk several kilometres at a time.
The stimulation is personalised to Marc. Nevertheless, the team thinks a similar technique could help many people. But there are at least five more years of development before the treatment will reach people outside a trial, says Courtine.

9 . Launched in 2004 by then-Harvard University student Mark Zuckerberg, Facebook became the biggest social media platform in the world just five years later. It was young people who helped Facebook initially shoot to success, but today’s youth think that “Facebook is for old people”, reported the Daily Star.
In 2015, a survey found that 71 percent of teens aged 13 to 17 used Facebook. But in 2022, that number dropped to 32 percent, reported NBC News. Alex Tani, a 25-year-old from the UK, said that when he started university in 2016, his tutors always set up student groups on Facebook to help everyone stay in touch and interact. But by the time his younger brother went to university three years later, this wasn’t the case.
Today’s younger generation prefers to use other social platforms, such as Instagram, a photo and video-sharing social networking service also owned by Facebook’s parent company Meta, and TikTok, owned by Chinese company ByteDance, said NBC News. These two platforms are different from Facebook in that they are mainly image-based and video-based, not text-based. Visual culture is a rising trend and young people have grown tired of reading people’s remarks on Facebook, said Forbes.
Another reason for Facebook’s decline in popularity is AI. According to The Guardian, TikTok’s “most powerful tool” is its algorithm (算法) which predicts what content you want to see. It shares related content with you from people you may not follow based on what you’ve watched before. This saves people the effort of searching for what they like, and so becomes an “escape for them”, said North Carolina State University.
Going forward, Facebook plans to use AI in a similar way as TikTok to show short videos and give users a better platform to discuss video content, said Fortune Media. Only time will tell whether it can stay “young” or remain as a platform used only by “old people”.
