1 . Because the commercial internet has been developed with so little regard for privacy, tech companies have been able to turn personal data into considerable profits, raising billions of dollars off their ability to collect and sell information about anyone who has wandered within shouting distance of their software. This week, Google announced a step in the right direction-but not a huge step, nor one that will stop Google from continuing to collect immense amounts of personal data.

At issue is how online companies track internet users as they browse (浏览) from site to site online, typically through cookies (information that a website leaves in your computer so that the website will recognize you when you use it again). The most harmful version, “third-party” cookies, is the web alternative of a company posting security guards across the internet to monitor what you do, even when you’re on other companies’ sites.

Google declared in a blog post Wednesday that it would no longer use or support third-party cookies, nor would it create or use any other technology that tracks individual users across the web. Given that Google is a main supplier of online advertising technology, its change in approach will impact far and wide.

That’s welcome news, although with huge amounts of warning. As Lee Tien of the Electronic Frontier Foundation noted, third-party cookies were already on the retreat, with Apple and other makers of popular web browsers moving to block them. Meanwhile, Google, Facebook and other Big Tech companies continue to collect personal information in large quantities from people who use their sites and services through first-party cookies and similar techniques.

The concerns about personal data collection are the same whether it’s being collected through first-party or third-party techniques, said Michelle Richardson of the Center for Democracy and Technology. “Companies may use the information to discriminate among internet users, offering different goods, services and even prices to different users.”

Instead of helping advertisers track individuals, Google says, it is improving a technology that assigns users namelessly to large groups with common interests. That’s an improvement, even though it too may be at risk of abuse. But why do any form of tracking at all? Privacy advocates say pitches (兜售) can be targeted effectively by basing them on where the user is at the moment, not where he or she has browsed previously online.

Ultimately, lawmakers are going to have to lay down regulations giving people far more control over whether and how personal information is used online. Ideally the federal (联邦的) government will set a strong floor under online privacy protections, but until then it will be up to state lawmakers or voters to act, as this state has done with its groundbreaking online privacy laws. It’s good to see Google move the ball forward, but there’s much farther to go.

2 . A small bowl bought at a yard sale in Connecticut for just $ 35 has been identified as a rare 15th-century Chinese antique.

The blue-and-white bowl was made by China's royal court during the Ming dynasty. It is now expected to sell for up to $500,000, according to Sotheby's auction(拍卖)house in New York, where the auction will take place next month.

The purchase was made last year near New Haven, Connecticut. “I was just hanging around there aimlessly. But when I saw this bowl, I didn't even bargain over the $35 asking price,” the owner said. Shortly after the purchase, he sent photos of the bowl to auction specialists, who identified it as an item of historical significance.

Upon closer inspection, the artifact was found to have originated from the period of Yongle Emperor, who ruled from 1403 to 1424 - a period noted for its distinctive porcelain (瓷器)techniques. It's now valued between $300,000 and $500,000, with the top estimate nearly 14,300 times the amount it was purchased for.

“I was deeply attracted by the techniques. You can see why this bowl is so highly-valued from the very smooth porcelain body, silky glaze(上釉)and special blue coloring, which were never reproduced in later dynasties,” McAteer, an auction specialist, said.

“The Yongle Emperor improved the porcelain techniques and elevated the importance of porcelain from being an ordinary bowl into a true work of art. This small bowl has both practical and artistic value, ”McAteer said.

3 . Constantly forcing knowledge and experiences into your brain may seem like the quickest path to self-improvement. But sometimes the best thing you can do for your brian is absolutely nothing at all.

Taking time to space out — whether by showering, pulling weeds, or petting a dog — provides an opportunity for what psychologists call wakeful rest. It’s a time when you can put immediate tasks aside like how to meet the work deadline and instead focus on current feelings, reflect on the past, and think about the future.

In the blankness, MRI (磁共振) brain imaging shows a harmony of gray matter called the default mode network (默认模式网络) takes control. Neuroscientists (神经系统科学家) still don’t completely understand how this system works, but they think it connects inharmonious parts of our brains, which can help us find meaning in our messy lives. “This blankness might also reduce anxiety, boost creativity, and improve memory,” says Mary Helen Immordino-Yang, a neuroscientist at the University of Southern California’s Brain and Creativity Institute.

The trouble is, the battle of life leaves little room to let your mind wander. Many spend their free time-consuming entertainment. It may feel relaxing but requires brainpower to enjoy. Fortunately, there are ways to encourage your resting-state network to take over:

FIND YOUR JOY

Casual hobbies that are totally different from your day job can help prevent out-of-office anxiety.

GET AWAY

New surroundings give your brain a break from environmental cues, like the sight of your desk and laptop, that tell it to work.

SWITCH OFF

Information can be too attractive to ignore. Turning off any and all devices helps maintain relaxation mode.

4 . The idea of billions of people going through a few masks a week during this pandemic definitely rings alarm bells, but a team of researchers in Melbourne may have the solution.

They’ve discovered that adding millions of discarded face masks to road-paving (铺路) mixtures would actually lower the cost of the road, while preventing billions of them from landfills. Just one kilometer of road would need three million masks, and the polypropylene (聚丙烯) plastic used to make single-use surgical face masks also increased the flexibility and durability of the road.

The new material is a mixture of about 2% torn masks, with recycled concrete aggregate (RCA)—a material obtained from waste concrete and other minerals from destroyed buildings. This recycled material was found in the study to be ideal for two of the four layers generally required to create roadways. Paving a kilometer of two-way road with the RCA and three million face masks would result in a change of 93 tons of waste from landfills.

The final product then is more resistant to wear than asphalt (沥青), as well as being cheaper too, provided there was a method for collecting masks. The research team did a cost-analysis and found that, at $26 per ton, the RCA was about half the cost of mining raw materials, and as much as a third of the cost of shipping the used masks to a landfill.

The widespread application would be ideal for large infrastructure (基础设施) projects. For example, Washington has the 11th worst roads in terms of unaddressed repairs in the U.S. If the damaged roads in Washington state were repaired with the RCA/mask mixture, it would reuse nearly 10 billion masks, sparing American landfills hundreds of millions of tons of trash.

It’s said that the team is looking for private industry partners or governments willing to give their plastic mask road an opportunity for a large-scale test.

6 . Have you ever loved a destination but couldn’t figure out why — or even a way ——to express your feelings? That’s my dilemma with Morocco.

In August, I traveled in a country that had long been, on my wish list. I rode a camel, got lost in Medinas, and ate more couscous (粗麦粉) than was humanly possible.

I loved the trip. Our friendly guide introduced us to the helpful locals. I made friends with my tour mates and my roommate (which, on a tour, is a huge blessing). I loved being lost in the smell of different spices, and the chaos of millions of people and the dark red of the Sahara were all I wanted them to be.

There were many moments when I felt like a fish out of water and things didn’t go my way. But I take pleasure in those moments because it’s when you are pushed out of your comfort zone that you grow. Morocco lived up to all my expectations, but for some reason, my experience has been hard to express. Why?

One constant in my travels is that of a touchstone, one defining point where the trip all comes together and acts as a prism (三棱镜) for everything the journey represented . In Costa Rica，it was getting lost in a jungle. In Thailand, it was meeting those five people who changed my life.

I’m so inconsistent about Morocco because I lack that touchstone. There’s no “whoa” moment. But I have thousands of little ones - staring at a million stars in the blackness of the desert, discovering new foods with some amazing Australians on my tour, and befriending the fish sellers.
