1 . Scientists regularly make vital new discoveries, but few can claim to have invented an entirely new field of science. Chemist Carolyn Bertozzi is one of them. Her discovery of biorthogonal chemistry (生物正交化学) in 2003 created a brand-new discipline of scientific investigation, which has enabled countless advances in medical science and led to a far greater understanding of biology at a molecular (分子的) level. On October 5, Bertozzi was awarded the Nobel Prize in Chemistry, jointly with two other professors. She is also the only woman to be awarded a Nobel Prize in science this year, after an all-male line-up in 2021.
Bertozzi was the middle daughter of an MIT physics professor and a secretary. Few predicted that Bertozzi would be the most famous person in the family. While her academic performance was not bad in high school, she was fond of playing soccer. She end ed up being admitted to Harvard University. Despite her talent in soccer, she found it too time-consuming and quit the sport to devote herself to academics.
But before becoming a rock star scientist, Bertozzi almost became an actual rock star. When she started at Harvard, she was tempted to major in music. That idea was “unpopular” with her parents, and she was timid about defying them. Instead, she chose the premed (医学预科的) track that included classes in math and sciences, and declared herself a biology major at the end of her first year of college.
Her interest in music did not completely fall by the wayside, however. Bertozzi played keyboards and sang backup vocals for a hair metal band. Bertozzi, however, did not play with the band for long. Once the band’s practices and performances conflicted with her labs and classes, there was only one outcome.
Plus, she’d soon have organic chemistry to think about a course which is infamous for weeding out pre-meds. Without any clear career ambitions up to that point, Bertozzi had been thinking about possibly becoming a doctor when, in her sophomore year (大二学年), she suddenly fell so head over heels in love with her chemistry course that she couldn’t tear herself away from her textbooks long enough to go out on Saturday nights. A torture to many was pure pleasure for her. Bertozzi changed her major from biology to chemistry a year later.
Bertozzi has sometimes joked about her having missed out on her chance to follow Morello to LosAngeles. “I didn’t get on that bus, and my playing is now limited to ‘The Wheel's on the Bus Go Round,’ I’m waiting for my sons to get old enough to appreciate 1980s heavy metal!”

2 . Willie Sutton, a once celebrated American criminal, was partly famous for saying he robbed banks because “that’s where the money is.” Actually, museums are where the money is. In a single gallery there can be paintings worth more, taken together, than a whole fleet of jets. And while banks can hide their money in basements, museums have to put their valuables in plain sight.
Nothing could be worse than the thought of a painting as important as The Scream, Edvard Munch’s impressive image of a man screaming against the backdrop of a blood-red sky, disappearing into a criminal underworld that doesn’t care much about careful treatment of art works. Art theft is a vast problem around the world. As many as 10,000 precious items of all kinds disappear each year. And for smaller museums in particular, it may not be a problem they can afford to solve. The money for insurance on very famous pictures would be budget destroyers even for the largest museums.
Although large museums have had their share of embarrassing robberies, the greatest problem is small institutions. Neither can afford heavy security. Large museums attach alarms to their most valuable paintings, but a modest alarm system can cost $500,000 or more. Some museums are looking into tracking equipment that would allow them to follow stolen items once they leave the museums. But conservators are concerned that if they have to insert something, it might damage the object. Meanwhile, smaller museums can barely afford enough guards, relying instead on elderly staff.
Thieves sometimes try using artworks as money for other underworld deals. The planners of the 2006 robbery of Russborough House near Dublin, who stole 18 paintings, tried in vain to trade them for Irish Republican Army members held in British prison. Others demand a ransom (赎金) from the museum that owns the pictures. Once thieves in Frankfurt, Germany, made off with two major works by J.M.W. Turner from the Tate Gallery in London. The paintings, worth more than $80 million, were recovered in 2012 after the Tate paid more than $5 million to people having “information” about the paintings. Though ransom is illegal in Britain, money for looking into a case is not, provided that police agree the source of the information is unconnected to the crime. All the same, where information money end s and ransom begins is often a gray area.

3 . The Savitzs who move to Newton had found themselves welcomed into the neighborhood with truly open arms. Glenda was pregnant before the move and within three months, they gave birth to Samantha. About a week after Glenda and RaphiSavitz welcomed their daughter Samantha to the world, they learned that she was deaf. “We knew right away that we had to get involved in the deaf community, learn about the culture, and start getting fully lost in American Sign Language,” Glenda says. What the new parents didn’t know was that their neighbors in Newton, Mass., would decide they needed to start learning sign language, too.
“We really wanted to communicate with her and play with her,” says McNeil, who lives across the street from the Savitzs. “And since she couldn’t learn our language, we thought we wanted to learn hers.” McNeil and three other neighbors quietly signed up for local adult education classes in American Sign Language. “We met a teacher there that we really loved, and we asked him if he would come here and teach more neighbors,” McNeil explains. “So that’s how it started.” About 20 neighbors immediately signed up for the class. With the help of their instructor, Rhys McGovern, the neighbors are able to help Samantha feel like she belongs.
“We know how to say, ‘Are you riding your bike?’ or ‘You have pretty new pink sneakers.’ There’s a dog across the street that she loves to play with. So we all know the sign for ‘dog.’” McNeil adds, “Her parents translate for us because her fingers are very small right now and she signs very fast, so we’re trying and we’re getting better. ... Her first sign to all of us is ‘friend,’ which feels very good.”
The classes have been such a hit that there are now two offerings, on two different weeknights, bringing the number of neighbors learning the language to about 40. As a result of that neighborly effort, Samantha moves with ease where her family lives. She’ll stop in at neighbors’ homes just to draw pictures and chat.

5 . It’s breathtaking to watch the delicate spring wildflowers come out from their blanket of leaves, bloom, develop and disperse (传播) fruit, all in a matter of a few short days or weeks.
Although they look fragile, these are tough little plants, each focusing its efforts on spreading its species. They have evolved to have a wide range of flower structures and colors, some with fragrances, attracting many different insect species to assist them in pollination (授粉).
There is one strategy (策略) that a surprising number of spring blooming native plants have evolved in common: seed dispersal by ants. As many as thirty percent of the spring flowering plant species in the forests of eastern North America have evolved to take advantage of this situation to benefit themselves. These species have evolved to provide food attached to their seeds to encourage ants to disperse those seeds. This food, called an elaiosome, is a specialized fat body whose chemical composition more closely matches that of the insects that ants prefer than it does that of a seed.
When a fruit opens to disperse its seeds, the elaiosomes are an instant attraction for ants. They take the seed with its attached elaiosome back to their nests for consumption there, but they just eat the elaiosome, their preferred food, and dispose of the seed on their trash pile. This tends to be an environment that is rich in nutrients, and will benefit the growth of the new plant. Just to make sure the ants don’t eat the seeds in addition to the elaiosome, some plant species have hard seed coatings that ants can’t really bite through.
This evolutionary adaptation is somewhat similar to the strategy of plants that have evolved to surround their seeds with fleshy fruits to attract birds to assist them with seed dispersal. Given the fact that there are fewer birds available in early spring to help with seed dispersal, it makes sense that the early blooming plants evolved to partner instead with the ants for this service.

6 . A recent discovery shows that our dance style is almost always the same, regardless of the type of music, and a computer can identify the dancer with astounding accuracy. Over the last few years, researchers at the Centre for Interdisciplinary Music Research at the University of Jyväskylä in Finland have used motion capture (动作捕捉) technology — the same kind used in Hollywood — to learn that your dance moves say a lot about you, such as how active or anxious you are, what mood you happen to be in, and even how much you empathize (共情) with other people. Recently, however, they discovered something that surprised them. “We actually weren’t looking for this result, as we set out to study something completely different,” explains Dr. Emily Carlson, the first author of the study.
The 73 participants in the study were motion captured dancing to seven different genres: Blues, Country, Dance/Electronica, Jazz, Metal, Pop and Rap. The only instruction they received was to listen to the music and move any way that felt natural. “We think it’s important to study phenomena as they occur in the real world, which is why we employ a naturalistic research example,” says Professor Petri Toiviainen, the senior author of the study.
The researchers analysed participants’ movements using machine learning, trying to distinguish between the musical styles. Unfortunately, their computer was able to identify the correct style less than 30% of the time. They were shocked to discover, however, that the computer could correctly identify which of the 73 individuals was dancing 94% of the time. “It seems as though a person’s dance movements are a kind of finger print,” says Dr. PasiSaari, co-author of the study and data analyst. “Each person has a unique movement signature that stays the same no matter what kind of music is playing.”Does this mean that face-recognition software will soon be joined by dance-recognition software? “We’re less interested in applications like surveillance(监视) than in what these results tell us about human musicality,” Carlson explains. “We have a lot of new questions to ask, like whether our movement signatures stay the same across our lifespan.”

7 . Day tour from Edinburgh
Start our journey in Edinburgh at 8:30am and travel north to South Queensferry Forth Bridges Viewpoint to get a great view of one of Scotland’s greatest man-made landmarks, the Forth Rail Bridge.
You then travel the short distance to Blackness Castle. It’s an impressive castle that’s known as the ‘ship that never sailed’ because it resembles a giant stone boat. Stand in awe of the formidable fortress — this was not only a noble residence but also a stronghold built for war. Climb the towers and curtain wall for sweeping views of the Firth of Forth and its rail and road bridges. Your next stop is Stirling Castle, one of Scotland’s greatest stone castles. The castle peaked in importance in the 1500s, but its volcanic crag has been fortified since ancient times. You then travel the short distance to the National Wallace Monument. It is one of Scotland’s most celebrated landmarks. The stunning 67 metre tower is instantly recognisable, and attracts more than 100,000 visitors every year. The NationalWallace Monument is a tower standing on the shoulder of the Abbey Craig, a hilltop overlooking Stirling in Scotland. It commemorates Sir William Wallace, a 13th-century Scottish hero.Your final stop of the day is Linlithgow Palace. Here you have time to walk by the loch for about an hour. Explore the magnificent ruins of the birthplace of Mary Queen of Scots. Linlithgow Palace was built and added to over two centuries by the Stewart kings, resulting in a superb Renaissance residence.

8 . DerlinNewey, an 89-year-old man from Weber County, Utah, has already reached an impressive age, but his Social Security checks aren’t covering his expenses. He works for a local Papa John’s as a delivery man, and despite being forced to work at his advanced age, he hasn’t let that affect his attitude — something the Valdez family recognized and honored.
Fans of pizza, the Valdezes order Papa John’s quite often. And when they do, they specifically request Newey, who always shows up with his signature greeting: “Hello, are you looking for some pizza?” The Valdezes, who have over 60,000 followers on TikTok, have featured Newey in the past, and their viewers have fallen in love with the elderly gentleman. “Everybody loves him,” Dad Carlos Valdez said.
The family has grown so fond of him that they decided to do something wonderful for the man. After they started a fundraiser for Newey, it wasn’t long before generous donors had given to the tune of $12,000 — a sizable amount by any standard, but especially so for someone in Newey’s shoes. “Collectively as a community, we all came together, and we were able to raise $12,000 for this amazing person,” CarlosValdez explained. “Somebody at that age should not be working that much.”
All that was left was to surprise Newey in his own home, making a special delivery to their special delivery man. “Good morning, dude! How are you doing?” CarlosValdez greeted Newey. The “TikTok famous” delivery man thought he was going to bring him a shirt with his signature saying (which he did), but he got far more than he had expected when CarlosValdez handed him a fat envelope stuffed with cash.
Newey didn’t even know what TikTok was, asking “Is that an online group you communicate with each other through the telephone?” “This couldn’t have gone any better,” CarlosValdez said. “He needed this. I’m just glad we could help him. We just need to treat people with kindness and respect the way he does. He stole our hearts.”

10 . The world’s coral reefs do more for the planet than provide underwater beauty. They protect shorelines from the effects of hurricanes. An estimated 500 million people earn their livelihood from the fishing stocks and tourism opportunities reefs provide. The tiny animals that give rise to reefs are even offering hope for new drugs to treat cancer and other diseases.
Despite their importance, warming waters, pollution, ocean acidification, overfishing, and physical destruction are killing coral reefs around the world. So now scientists around the world are looking for all kinds of ways to protect and maybe even revive(复苏) corals. In the Bahamas, Ross Cunning, a research biologist at Chicago’s Shedd Aquarium, is focusing on corals with genes that could make them natural candidates for restoration projects. He recently published a study of two Bahamian reefs, one that seemed to survive an intense 2015 heat wave, and one that didn’t.“It sets the stage to find out which genes are responsible for thermal tolerance,” says Cunning, adding that he hopes discovering those genes will help scientists one day breed more heat-tolerant coral.
In Massachusetts, Cohen’s research has found two key elements that seem to protect corals. The first: internal(内部的) waves beneath the ocean’s surface that bring cooler currents to heat-struck corals, essentially air-conditioning them as temperatures rise. The second: adaptation, a quality that corals found in Palau’s warm lagoons(环礁湖) seem to display.On average, these lagoons submerge(淹没) coral in water that is two degrees Celsius warmer than the water outside the lagoons. “We think the fact that they can deal with these higher temperatures is built into their genetics and allows them to deal with the heat waves.”
She’s also found evidence of corals evolving more quickly in the past two decades to withstand rapidly warming temperatures. The big question scientists are now enquiring into, says Cohen, is whether there’s a cap on how much more heat corals can adapt to. Cohen calls these regions with heat-adapted corals as “super reefs,” and like Friendlander, advocates for using marine reserves to protect them.
