Two things changed my life: my mother and a white plastic bike basket. I have thought long and hard about it and it’s true. I would have been a different person if my mom hadn’t turned a silly bicycle accessory (配饰) into a life lesson I carry with me today.
My mother and father were united in their way of raising children, but it mostly fell to my mother to actually carry it out. Managing the family budget must have been a very hard task, but she made it look effortless. If we complained about not having what another kid did, we’d hear something like, “I don’t care what so-and-so got for his birthday, you are not getting a TV in your room, a car for your birthday, a lavish sweet 16 party.” We had to earn our allowance by doing chores around the house. I can still remember how long it took to polish the legs of our coffee table. My brothers can no doubt remember hours spent cleaning the house. Like the two little girls growing up at the White House, we made our own beds. We had to keep track of our belongings, and if something was lost, it was not replaced.
It was summer and, one day, my mother drove me to the bike shop to get a tire fixed — and there it was in the window. White, shiny, plastic and decorated with flowers, the basket winked at me and I knew — I knew — I had to have it.
“It’s beautiful,” my mother said when I pointed it out to her, “What a neat basket.”
I tried to hold off at first, and I played it cool for a short while. But then I guess I couldn’t pretend to ignore it any longer: “Mom, please can I please, please get it? I’ll do extra chores for as long as you say. I’ll do anything, but I need that basket. I love that basket.”
I was desperate.
“You know,” she said, gently rubbing my back while we both stared at what I believed was the coolest thing ever. “If you save up you could buy this yourself.”
“By the time I make enough it’ll be gone!”
“Maybe Roger here could hold it for you,” she smiled at Roger, the bike guy.
“Mom. Someone else will buy it.”
“There might be another way,” she said.

You are what you eat-and what you eat may be encoded in your DNA. Studies have indicated that your genes play a role in determining the foods you find delicious or disgusting. But exactly how big a role they play has been difficult to figure out. “Everything has a genetic component even if it’s small,” says Joanne Cole, a geneticist at the University of Colorado School of Medicine. “We know that there is some genetic contribution to why we eat the foods we eat. Can we take the next step and actually locate the regions in the genome (基因)?”
New research led by Cole has gotten a step closer. Through a large-scale genomics analysis, her team has identified 481 genome regions that were directly linked to dietary patterns and food preferences. The findings, which have not yet been peer-reviewed, were presented last month at the American Society for Nutrition’s annual conference.
The team based the new study on a 2020 Nature Communications study by Cole and her colleagues that used data from the U.K. Biobank, a public database of the genetic and health information of 500,000 participants. By scanning genomes, the new analysis was able to identify 194 regions associated with dietary patterns and 287 linked to specific foods such as fruit, cheese, fish, tea and alcohol. Further understanding how genetics impact how we eat could reveal differences in nutritional needs or disease risks.
“One of the problems with a lot of these genomics studies is that they’re very small. They don’t have enough people to really be able to identify genes in ways that are credible. This study had a huge group of people, so it’s really powerful.” says Monica Dus, a geneticist at the University of Michigan. “The other thing that I thought was really great is that there are so many different features that they’re measuring related to diet including cholesterol (胆固醇), the body and socioeconomic backgrounds.” As the research advances, Dus says, such genome analysis could potentially assist health care providers and even policymakers to address larger issues that affect food access and health.
It’s definitely true that it may contribute to making sure there aren’t food deserts-areas which have limited access to fresh, healthy and affordable food or to making sure that there’s a higher minimum wage so that everyone can afford to eat, although the journey ahead remains lengthy and challenging.

9 . Atomic shapes are so simple that they can’t be broken down any further. Mathematicians are trying to turn to artificial intelligence (AI) for help to build a periodic table of these shapes, hoping it will assist in finding yet-unknown atomic shapes.
Tom Coates at Imperial College London and his colleagues are working to classify atomic shapes known as Fano varieties, which are so simple that they can’t be broken down into smaller components. Just as chemists arranged element s in the periodic table by their atomic weight and group to reveal new insights, the researchers hope that organizing these atomic shapes by their various properties will help in understanding them.
The team has given each atomic shape a sequence of numbers based on its features such as the number of holes it has or the extent to which it bends around itself. This acts as a bar code (条形码) to identify it. Coates and his colleagues have now created an AI that can predict certain properties of these shapes from their bar code numbers alone, with an accuracy of 98 percent.
The team member Alexander Kasprzyk at the University of Nottingham, UK, says that the AI has let the team organize atomic shapes in a way that begins to follow the periodic table, so that when you read from left to right, or up and down, there seem to be general patterns in the geometry (几何) of the shapes.
Graham Nib lo at the University of Southampton, UK, stresses that humans will still need to understand the results provided by AI and create proofs of these ideas. “AI has definitely got unbelievable abilities. But in the same way that telescopes (望远镜) don’t put astronomers out of work, AI doesn’t put mathematicians out of work,” he says. “It just gives us new backing that allows us to explore parts of the mathematical landscape that are out of reach.”
The team hopes to improve the model to the point where missing spaces in its periodic table could point to the existence of unknown shapes.

One late afternoon, Tina was driving on a highway when a severe snowstorm hit with no sign before. In a short time, the heavy snow, coupled with the strong wind, turned everything into white and made the road extremely dangerous.
Tina later found out that this kind of storm is called a “Saskatchewan screamer”, which comes on extremely fast with high winds. It’s really frightening and deadly to be caught in such extreme weather.
Unable to see the road clearly, Tina had to stop her car and call 911. The operator told her that phone calls for help kept flooding in and all the rescuers had been called out. She suggested that Tina should wait out the storm in her car rather than risk driving on or going out. She took Tina’s information and told her that an officer would call her back. Tina waited anxiously for almost two hours, but nobody called her yet to check in. “The storm showed no sign of stopping. What was worse, it was getting dark. I couldn’t see anything outside the car since the snow had covered all the windows. The wind was still howling and the temperature was getting lower and lower in the car. I had no idea whom I could turn to for help,” Tina later wrote in a Facebook post. “Alone and cold,I began to panic, worrying about getting hit by an oncoming vehicle, getting buried in a snowbank, having my tailpipe blocked by the snow... I was really worried I couldn’t ever make it home to my family."
That was when Tina realized that it was no use waiting passively for help. She decided to do something herself. So she took out her cellphone, logged on to the Google Map and determined her location. She found online a neighborhood Facebook group for the area that she was passing through and shared a comment about her trouble with her location marked on the map. Then all she could do next was sitting in the car, praying someone could make a response to her as early as possible.
Fortunately, Tina’s request reached 80-year-old retired rescuer Frank.
