2 . In a gray box, I have a thick pile of love letters. I imagine about sharing them with a granddaughter when I’m 90. But my most treasured love letter is from one of my best friends. It’s a handwritten letter years ago when I was having trouble getting over a man. Her letter is the most romantic in my pile. It made no excuses. It simply let me know that I was loved.
Reflecting on her gift, and the dying art of handwritten letters in our age of emails and emoticons, I chose to conduct an experiment this Christmas: replacing presents with heartfelt, handwritten love letters for my family members.
In our digital era, most of us rarely take the time to share deeply considered thoughts and emotions with the people in our lives. Handwriting captures the writer’s emotions, often preserved longer than digital exchanges. However, technology is taking over. First came typewriters and keyboards. Now a new brain-computer lets people type with their minds. What are we losing when we sacrifice the physical labor behind the written word? We tend to value what we struggle for. Have we undervalued the human exchange of ideas?
That day, I came across a letter my mom wrote to her parents when she was young. She seemed so comfortable with her parents. It was a relationship I didn’t have with her. I was inspired by my mother’s letter to her parents when I sat down to write my letter to her. I wanted her to know my love, and to close the crack that technology and culture had created between us. With each sentence, I was discovering new and deeper ways of seeing my mother, and making myself known to her in more thoughtful ways as well.
Eight single-space pages later, my hand was aching but I was done. It was only the first of my love letters, but it was already clear: What had begun as a fun project was in fact one of the most important undertakings of my life.

3 . When instant cake mixes first appeared in the 1950s, American housewives were doubtful. These mixes, promising easy cake-baking, felt too easy. The manufacturers discovered that requiring the addition of an egg in the baking process was just enough to make the housewives happy with their work. The greater sense of effort gained from a little extra labor is believed to have been essential to the later success of the cake mix.
This reflects the IKEA effect (宜家效应), which is identified by psychologist Michael I. Norton and his colleagues, suggesting we place greater value on things we have worked to create. They conducted four studies in which they asked participants to fold paper cranes and frogs, assemble IKEA boxes, and build sets of Legos. They then asked the builders to bid (出价) for their creations, and compared the prices with bids from people who hadn’t built them. The builders consistently outbid the non-builders.
Interestingly, the IKEA effect works even when people have no opportunity to fully personalize their creations. While most participants’ folding skills left much to be desired, they loved their imperfectly personalized products all the more. Builders valued their wrinkled crane-like creations nearly five times as much as non-builders. Beauty, it seems, is in the eye of the builder.
Today, as cities are suffering from severe housing crises, the IKEA effect can give us insight into the well-being benefits of a self-building approach to housing development. Projects like WikiHouse and the “half-a-house” approach pioneered by Alejandro Aravena’s architecture company Elemental are working to make housing more affordable and sustainable by making it easier for people to build and personalize their own homes.
“The moment people are involved with their built environment, they have a totally different relationship to it,” WikiHouse co-founder Alastair Parvin explained. “When the roof starts leaking or a door starts creaking, they have the power to fix it themselves.”

5 . When it comes to lowering blood pressure, studies have typically shown that aerobic (有氧的) exercises are best. Recent research suggests another type of physical activity is worth including as an effective tool to prevent and treat high blood pressure.
Exercises that engage muscles without movement, such as wall squats and planks, may be best for lowering blood pressure, according to a large study published in July, 2023 in the British Journal of Sports Medicine.
This type of training is known as isometric exercise, according to the Mayo Clinic. Isometric muscle action happens when muscles contract but do not visibly change length, and the joints involved don’t move, facilitating stability of the body. Isometric exercises can be done with weights or without, just relying on the body’s own weight.
“These findings provide a comprehensive data-driven framework to support the development of new exercise guideline recommendations for the prevention and treatment of high blood pressure,” said study coauthor Dr. Jamie O’Driscoll in a news release.
The researchers looked into randomized controlled trials that had reported the effects of exercise interventions, lasting two or more weeks, on blood pressure between 1990 and February 2023. From a review of 270 trials with 15,827 participants, the researchers found that among HIIT (high intensity interval training), isometric exercise, aerobic exercise, dynamic resistance training and a combination of the latter two, isometric exercise led to the greatest reductions in blood pressure.
It’s also important to note that there are other lifestyle changes as well as exercise that can benefit your blood pressure. These include keeping to a healthy weight, eating a balanced diet, cutting down on salt, not drinking too much alcohol and ensuring that you continue to take any prescribed medication.
More research is needed to determine exactly why isometric exercises might be better for lowering blood pressure than other types of training, the authors said.

9 . As reported in the journal Nature, one system can directly remove carbon dioxide from sources ranging from flue gas (烟道气) to the atmosphere by using electricity to induce a water-and-oxygen-based electrochemical reaction. This technological achievement could turn direct air capture (捕获) from edge industry into a promising front for climate change relief.
Most carbon-capture systems involve a two-step process: First, high-pH liquids are used to separate the carbon dioxide, which is acidic, from mixed-gas streams such as flue gas. Next, the carbon dioxide is regenerated from the solution through heating or by injecting a low-pH liquid.
“Once the carbon dioxide is trapped in these solvents (溶剂), you have to regenerate it,” says Haotian Wang, assistant professor at Rice University. “There are literally no chemicals produced or consumed with our process. We also don’t need to heat up or pressurize our device, we just need to put it into a power outlet and it will work.”
Another drawback of current carbon-capture technologies is their reliance on large-scale, centralized infrastructure. By contrast, the system developed in the Wang lab is an extensible, modular, point-of-use concept that can adapt to a variety of scenarios. “The technology can be scaled up to industrial settings-power plants, chemical plants-but the great thing about it is that it allows for small-scale use as well: I can even use it in my office.” Wang says.
Also the reactor can continuously remove carbon dioxide from a simulated (模拟的) flue gas with efficiency above 98% using a relatively low electricity input. Wang notes that the process has “no carbon footprint or a very limited footprint” if powered by electricity from renewable sources such as solar or wind. “This is great news considering that renewablel electricity is becoming more and more cost-effective,” Wang says.

10 . Around 3,500 Americans ingest (摄入) batteries every year. It’s apparently such a repeating issue that even a specific hotline was built in the event of such an emergency.
And while it’s unlikely your wristwatch’s power source will ever be safe to eat, that doesn’t mean all batteries will remain uneatable-in fact, some are being designed with digestion specifically in mind.
A team of researchers at the Italian Institute of Technology recently revealed what isl being called as the world’s first fully rechargeable, eatable battery. As detailed in a paper published with Advanced Materials, the new device has made good use of some eatable materials.
“Eatable electronic devices will have major implications for gastrointestinal tract (胃肠道) monitoring, treatment, as well as rapid food quality monitoring,” reads the paper’s abstract, adding that although recent research proved the feasibility of eatable sensors and circuits, “fully eatable electronic devices and eatable power sources are still required, of which there have been very few examples.”
According to the team’s findings, their proof-of-concept battery was capable of producing 0.65 volts, which is safely low enough for the human body to handle. The ingestible could provide 48 μA of current for 12 minutes, or alternatively, a few microamps (微安) for over an hour. Such a power supply could provide enough energy for small electronics alike to eatable pill-shaped modules and other gastrointestinal procedure alternatives.
In a statement, researcher coordinator Mario Caironi explained that such a product could help power monitors for both human health conditions and food storage. Additionally, given their safety, products with stronger power could be used within children’s toys, where ingestion risk is higher.
In the team’s statement, co-author Ivan Ilic also explained that despite the battery’s relatively low power, its digestibility provides a promising example of a battery that doesn’t use any harmful materials.
