Ingår i: Frontiers for Young Minds. - : Frontiers Media SA. - 2296-6846. ; 8

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Algebra is often introduced as arithmetic done with letters. In this article, we follow this analogy and see where it takes us. We ask questions such as: If "SNAPE = SNAKE", can we conclude that "P = K"? Here is the spoiler: the path takes us into what mathematicians call group theory, a subfield of algebra that studies symmetry, and allows us to say interesting things about various languages like English and Swedish (and one very important fact about algebra itself).

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Have you ever lost your phone and used its GPS function to locate it? To learn about fish, scientists are interested in where fish go and what they experience but GPS technology does not work underwater. Scientists therefore developed small electronic data loggers that can be attached to fish, to record conditions in a fish’s environment. When the fish is recaptured, this information can be downloaded and returned to the scientists. The fish’s movements can then be reconstructed by comparing the recorded measurements with the conditions in the sea. In this article, we explain how this method works and tell you the story of two cod with very dierent fates: Wally, who moved around to feed and to produce ospring, and Wilma, who went on an adventure with a surprising endin

The Silicon Cycle in the Ocean
- 2024
-
Ingår i: Frontiers for Young Minds. - 2296-6846. ; 11
-
Tidskriftsartikel (refereegranskat)abstract
- The element silicon is everywhere! In fact, silicon is the second most abundant element in Earth’s crust. Silicon in rocks and minerals breaks down and is transported from rivers and streams into the world’s oceans. Many marine organisms need silicon as it is a crucial nutrient to build their skeletons. Silicon eventually reaches the seafloor, but its journey into the abyss is not straightforward due to biological, physical, and chemical processes. All these processes transport and transform silicon, creating a cycle that we call the marine silicon cycle. The silicon cycle is directly connected to the carbon cycle, making silicon a key player in the regulation of Earth’s climate. In this article, we discuss why we need to understand the marine silicon cycle, explain the steps that happen in the ocean, and demonstrate how the marine silicon cycle affects humans.

The “Little Person” in the Brain Who Helps to Direct Our Movements
- 2023
-
Ingår i: Frontiers for Young Minds. - : Frontiers Media SA. - 2296-6846. ; 11

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The Brain Is Organized for Maximum Efficiency Our brains interpret the world around us, think, imagine, control our movements, and much more. This seems like a lot of work for one small organ! How can the brain control so many different tasks? The best way to deal with many duties is to distribute the work, and this is how the brain does it. Specific parts of the brain are responsible for processing what we see, controlling how we speak, regulating how we move, and so on. In a busy office building, people who need to speak to each other regularly will often have their desks near each other, but people who have very different jobs and tasks can work on separate floors. It would not make sense for members of the same team to go up and down the stairs all day when they could just sit together! Putting people with similar tasks near each other allows them to work faster. The brain uses a similar strategy. Similar brain functions are controlled by brain regions that are close to each other. This means that the brain regions that often work together can communicate quickly and efficiently.

The Pop and Color of Our Electrified Muscles
- 2022
-
Ingår i: Frontiers for Young Minds. - : Frontiers Media SA. - 2296-6846. ; 10

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We humans have more than 600 muscles in our bodies! You constantly use your muscles to eat, breathe, make faces, and run around! How many muscles do you think a person uses to play the piano, dance the macarena, or play basketball? How do you think the muscles get the message to move? We cannot see our muscles under the skin, so it is easy to forget about them. If you make the “strong arm” pose by flexing your elbow and clenching your fist, you might see a muscle bulge. Or if you get a lot of exercise, your muscles might get tired or sore. Would you like to be able to see what your muscles are doing under your skin? If you could listen really closely, do you think muscles make any sound? In fact, with some special recording equipment, it is possible to see and hear what muscles are doing!

Predicting the Future : How Does a Weather Forecast Work?
- 2023
-
Ingår i: Frontiers for Young Minds. - : Frontiers Media S.A.. - 2296-6846. ; 11
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Accurate weather forecasts are very useful, because they tell people what kind of weather to expect in the next few days. But how can we predict what will happen in the future? This article will explain how meteorologists, the people who study and work with the conditions that happen in the atmosphere, predict tomorrow’s weather. To help you understand weather predictions, we will first explain how changes in the atmosphere result in various types of weather. In this article, we will tell you how meteorologists turn knowledge of the conditions in the atmosphere into a weather forecast, just like you see in the news or on a weather app!

How Might Browner Seawater Affect Marine Organisms?
- 2024
-
Ingår i: Frontiers for Young Minds. - 2296-6846. ; 12
-
Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Climate change is having many negative impacts worldwide. Increased rainfall caused by climate change has become a serious issue in the northern parts of the world. With more rainfall, a larger amount of brown-colored decaying plant material is transported from the land to oceans, making the seawater browner. The brown color reduces the amount of sunlight that penetrates into the seawater, which can decrease the growth of microscopic plant-like organisms called phytoplankton that rely on sunlight to grow. Phytoplankton are an important food source for ocean animals, such as tiny creatures called zooplankton. This study explored the effects of seawater browning on phytoplankton and zooplankton in the northern Baltic Sea.

Tiny Fungi in the Soil Are Like Medicine for Nature
- 2020
-
Ingår i: Frontiers for Young Minds. - : Frontiers Media SA. - 2296-6846.
-
Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Like humans, plant and animal species have a specific type of place, called an ecosystem, where they prefer to live. If the ecosystem changes too much, some species will disappear, much the same way people avoid living in the desert because it is too hot and dry. Humans modify many ecosystems, sometimes so severely that almost no plants or animals can live there anymore. To help damaged ecosystems recover, we often start by planting trees or other plants. Biologists found that mycorrhizal fungi, tiny fungi living in the soil and inside plant roots, could speed up ecosystem recovery by making plants grow back faster and stronger. In this article, we describe how the recovery of ecosystems can be enhanced by mycorrhizal fungi, and when mycorrhizal fungi are especially helpful.

Did Algae Eat All the Silica in the World’s Oceans?
- 2024
-
Ingår i: Frontiers for Young Minds. - 2296-6846.
-
Tidskriftsartikel (refereegranskat)abstract
- Silicon is a crucial nutrient that can join with the element oxygen to form a substance commonly called silica. Silica, commonly known as glass, is found in rocks in the Earth’s crust and dissolves into the oceans, where organisms like algae and sponges use it to build their glassy skeletons. This process, called biosilicification, is extremely important in the silica cycle. Over time, organisms have changed the silica cycle. Today, because of these organisms, the oceans no longer contain much silica. However, when the Earth was younger and these organisms had not evolved yet, no biological processes affected silica in the oceans. The evolution of these oceanic organisms across time has removed silica from the oceans. In this article, we discuss how the evolution of silicon-using sponges, as well as tiny organisms called zooplankton and algae, have changed the amount of silica in the world’s oceans through geologic time.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Do the misty mountains, fast-flowing rivers, and sandy beaches leave you in awe and fill you with insatiable wonder? Does nature bring you a jubilant feeling? Nature contributes to our quality of life in multiple ways. Some of these gifts are easily visible, like the clothes you wear, the food you eat, and the water your drink. However, some contributions, such as flood protection and pollination of food crops are hardly ever seen. Scientists warn that we are now losing many of these gifts from nature, and this is why in this article we want to talk about it. In fact, one of the things we need to conserve nature is to understand why and how it is important for our lives. In this article, we introduce you to nature’s contributions to people and why it is important to assess them.

Working With Nature to Solve Societal Problems
- 2022
-
Ingår i: Frontiers for Young Minds. - : Frontiers Media SA. - 2296-6846. ; 10:643553
-
Tidskriftsartikel (refereegranskat)abstract
- Are you worried about the climate and biodiversity crises and related events like heavy rainfalls and floods, high carbon emissions, sudden heat waves, or loss of species? Are you already doing something to help solve these problems? To reduce flood risks, we can give rivers more space by reconnecting floodplains. To store carbon and help to slow down climate change, we can protect and establish wetlands or mangroves. To make cities cooler in summer, we can plant trees and install rooftop gardens. These efforts to help combat societal problems are known as nature-based solutions. To use nature-based solutions effectively, we need to understand how we can work with nature and the steps we must take to put these ideas into practice. In this article, we introduce you to the concept of nature-based solutions and how they can help solve the climate and biodiversity crises.

A “Dual Career” : Combining Sport and Studies
- 2022
-
Ingår i: Frontiers for Young Minds. - Lausanne : Frontiers Research Foundation. - 2296-6846. ; 10
-
Tidskriftsartikel (refereegranskat)abstract
- School-aged athletes face the need to balance competitive sports and their studies. In doing so they follow what is called a dual-career pathway. Both pursuits take time and effort, both are expected to lead to success, and either could lead to a life-long career. A dual-career pathway begins when children start to play sports and might continue throughout the school years and beyond. Research shows that it is beneficial to combine sport and studies, but it is also challenging. How can kids optimally juggle their sport, studies, social, and private lives? How do they gain the benefits of a dual career and avoid harming their prospects in sport or school? This article explains what a dual career is, why it is important, and why it is difficult. It also describes the skills and strategies for coping with dual-career challenges and presents tips from researchers to achieve success in dual-career pursuits. © 2022 Stambulova and Harwood
