Dealing with One Missed Workout
It’s a common dilemma (图局)for anyone on a training plan: You miss one workout and become awashed with guilt. To make up for it, you add those extra miles to your next workout. But according to the professionals, this isn’t the right way to go about it. “A single workout is not going to make or break a training plan. The key to training is consistency over time,” says John Raglin, PhD, professor in the Department of Kinesiology at Indiana University Bloomington.When you miss a workout, the temptation is to think, “Oh, I’ve got to do more tomorrow”. But when you try to catch up on your workouts, you run a couple of risks: “Certainly an injury, but also becoming over-tired, which could ruin your training after that, ” says Raglin. This is a phenomenon called ‘non-functional overreaching’, “he says. Eventually, this could lead to overtraining syndrome (综合症), which is characterized by a decrease in performance later due to a long-term increase in training load without adequate recovery.
So how do you move forward if you skipped a run or five?Well first, people download generalized training plans without understanding that they are meant to be adapted to life. There is a whole host of life stressors—job, kids, friendships, travel—and exercise is just another type of stress. Actually, when things get chaotic in your life, it may be necessary to just let go. Next, if you missed a workout, you have to ask yourself why: “Was it just because your schedule got out of hand or because you were feeling overly exhausted? ” Understanding why you missed the workout can offer some insights into how to tailor your program to suit your lifestyle.

New research confirms that human footprints found in New Mexico are probably the oldest direct evidence of human presence in the Americas, a finding that upends what many scientists knew about human habitation and migration (迁徙).
The footprints were discovered at the edge of an ancient lakebed in White Sands national park. According to the new paper published in the journal Science, they date back to between 21,000 and 23,000 years ago. Actually, the estimated age of the footprints was first reported in Science in 2021, but some researchers raised concerns about the dates. Questions focused on whether seeds of water plants used for the original dating may have absorbed ancient carbon from the lake — which could, in theory, throw off radiocarbon dating by thousands of years. But the new study presents two additional lines of evidence for the older date range. It uses two entirely different materials found at the site, ancient pollen (花粉) and stone grains.
The reported age of the footprints challenges the once conventional wisdom that humans did not reach the Americas until a few thousand years before rising sea levels covered the Bering land bridge between Russia and Alaska, perhaps about 15, 000 years ago. “This is a subject that's always been controversial because it's so significant. It's about how we understand the last chapter of the peopling of the world,” said Thomas Urban, an archaeologist (考古学家) at Comell University, who was involved in the 2021 study but not the new one.
Thomas Stafford, an independent archaeological geologist in New Mexico, who was not involved in the study, said he “was a bit suspicious before” but now is convinced. The new study isolated about 75, 000 grams of pure pollen from the same stone layer that contained the footprints. ‘Dating pollen is laborious but worthwhile,” said Kathleen Springer, a research geologist at the US Geological Survey and a co-author of the new paper.
Ancient footprints of any kind can provide archaeologists with a quick look of a moment in time. While some archeological sites in the Americas point to similar date ranges — including necklaces carved from giant animal remains in Brazil — scientists still question whether such objects really indicate human presence. “White Sands is unique because there's no question these footprints were left by people,” said Jennifer Raff, a scientist at the University of Kansas, who was not involved in the study.

9 . The cultivation of plants by ants is more widespread than previously realized, and has evolved on at least 15 separate occasions.
There are more than 200 species of ant in the Americas that farm fungi (真菌) for food, but this trait evolved just once sometime between 45 million and 65 million years ago. Biologists regard the cultivation of fungi by ants as true agriculture appearing earlier than human agriculture because it meets four criteria: the ants plant the fungus, care for it, harvest it and depend on it for food.
By contrast, while thousands of ant species are known to have a wide variety of interdependent relationships with plants, none were regarded as true agriculture. But in 2016, Guillaume Chomicki and Susanne Renner at the University of Munich, Germany, discovered that an ant in Fungi cultivates several plants in a way that meets the four criteria for true agriculture.
The ants collect the seeds of the plants and place them in cracks in the bark of trees. As the plants grow, they form hollow structures called domain that the ants nest in. The ants defecate (排便) at designated absorptive places in these domain, providing nutrients for the plant. In return, as well as shelter, the plant provides food in the form of fruit juice.
This discovery prompted Chomicki and others to review the literature on ant-plant relationships to see if there are other examples of plant cultivation that have been overlooked. “They have never really been looked at in the framework of agriculture,” says Chomicki, who is now at the University of Sheffield in the UK. “It’s definitely widespread.”
The team identified 37 examples of tree-living ants that cultivate plants that grow on trees, known as epiphytes (附生植物). By looking at the family trees of the ant species, the team was able to determine on how many occasions plant cultivation evolved and roughly when. Fifteen is a conservative estimate, says Campbell. All the systems evolved relatively recently, around 1million to 3 million years ago, she says.
Whether the 37 examples of plant cultivation identified by the team count as true agriculture depends on the definitions used. Not all of the species get food from the plants, but they do rely on them for shelter, which is crucial for ants living in trees, says Campbell. So the team thinks the definition of true agriculture should include shelter as well as food.

10 . Montessori was born in Italy in 1870 with progressive parents, who frequently communicated with the country’s leading thinkers and scholars. This enlightened family environment provided Montessori with many advantages over other young girls of the time.
Her mother’s support was vital for some important decisions, such as her enrolment in a technical school after her elementary education. Her parents’ support also proved to be essential for her decision to study medicine, a field that was dominated by men.
Soon after graduating, in 1896, Montessori began work as a voluntary assistant in a clinic at the University of Rome, where she cared for children with learning difficulties. The rooms were bare, with just a few pieces of furniture. One day, she found that the children were enthusiastically playing with breadcrumbs (面包屑) that had dropped on the floor. It then occurred to her that the origin of some intellectual disabilities could be related with poverty. With the right learning materials, these and other young minds could be nurtured, Montessori concluded.
The observation would lead Montessori to develop a new method of education that focused on providing optimal stimulation during the sensitive periods of childhood.
At its centre was the principle that all the learning materials should be child-sized and designed to appeal to all the senses. In addition, each child should also be allowed to move and act freely, and use their creativity and problem-solving skills. Teachers took the role of guides, supporting the children without press or control.
Montessori opened her first Children’s House in 1907. When the Fascists (法西斯主义者) first came into power in Italy in 1922, they initially embraced her movement. But they soon came to oppose the emphasis on the children’s freedom of expression. Montessori’s values had always been about human respect, and the rights of children and women, but the Fascists wanted to use her work and her fame.
Things reached a breaking point when the Fascist tried to influence the schools’ educational content, and in 1934 Montessori and her son decided to leave Italy. She didn’t return to her homeland until 1947, and she continued to write about and develop her method until her death in 1952, at the age of 81.
