May the Four Forces Be With You!
May the force be with you? Much to learn you still have, padawan. In our universe it would be more appropriate to say, “May the four forces be with you.”
There are four fundamental forces that bind our universe and its building blocks together. Two of them are easy to spot — gravity keeps your feet on the ground while electromagnetism keeps your devices running. The other two are a little harder to see directly in everyday life, but without them, our universe would look a lot different!
Let’s explore these forces in a little more detail.
Gravity: Bringing the universe together
If you jump up, gravity brings you back down to Earth. It also keeps the solar system together … and our galaxy, and our local group of galaxies and our supercluster of galaxies.
Gravity pulls everything together. Everything, from the bright centers of the universe to the planets farthest from them. In fact, you (yes, you!) even exert a gravitational force on a galaxy far, far away. A tiny gravitational force, but a force nonetheless.

Despite its well-known reputation, gravity is actually the weakest of the four forces. Its strength increases with the mass of the two objects involved. And its range is infinite, but the strength drops off as the square of the distance. If you and a friend measured your gravitational tug on each other and then doubled the distance between you, your new gravitational attraction would just be a quarter of what it was. So, you have to be really close together, or really big, or both, to exert a lot of gravity.
Even so, because its range is infinite, gravity is responsible for the formation of the largest structures in our universe! Planetary systems, galaxies and clusters of galaxies all formed because gravity brought them together.
Gravity truly surrounds us and binds us together.
Electromagnetism: Lighting the way
You know that shock you get on a dry day after shuffling across the carpet? The electricity that powers your television? The light that illuminates your room on a dark night? Those are all the work of electromagnetism. As the name implies, electromagnetism is the force that includes both electricity and magnetism.
Electromagnetism keeps electrons orbiting the nucleus at the center of atoms and allows chemical compounds to form (you know, the stuff that makes up us and everything around us). Electromagnetic waves are also known as light. Once started, an electromagnetic wave will travel at the speed of light until it interacts with something (like your eye) — so it will be there to light up the dark places.
Like gravity, electromagnetism works at infinite distances. And, also like gravity, the electromagnetic force between two objects falls as the square of their distance. However, unlike gravity, electromagnetism doesn’t just attract. Whether it attracts or repels depends on the electric charge of the objects involved. Two negative charges or two positive charges repel each other; one of each, and they attract each other. Plus. Minus. A balance.
This is what happens with common household magnets. If you hold them with the same “poles” together, they resist each other. On the other hand, if you hold a magnet with opposite poles together — snap! — they’ll attract each other.
Electromagnetism might just explain the relationship between a certain scruffy-looking nerf-herder and a princess.
Strong Force: Building the building blocks

The strong force is where things get really small. So small, that you can’t see it at work directly. But don’t let your eyes deceive you. Despite acting only on short distances, the strong force holds together the building blocks of the atoms, which are, in turn, the building blocks of everything we see around us.
Like gravity, the strong force always attracts, but that’s really where their similarities end. As the name implies, the force is strong with the strong force. It is the strongest of the four forces. It brings together protons and neutrons to form the nucleus of atoms — it has to be stronger than electromagnetism to do it, since all those protons are positively charged. But not only that, the strong force holds together the quarks — even tinier particles — to form those very protons and neutrons.
However, the strong force only works on very, very, very small distances. How small? About the scale of a medium-sized atom’s nucleus. For those of you who like the numbers, that’s about 10-15 meters, or 0.000000000000001 meters. That’s about a hundred billion times smaller than the width of a human hair! Whew.
Its tiny scale is why you don’t directly see the strong force in your day-to-day life. Judge a force by its physical size, do you?
Weak Force: Keeping us in sunshine
If you thought it was hard to see the strong force, the weak force works on even smaller scales — 1,000 times smaller. But it, too, is extremely important for life as we know it. In fact, the weak force plays a key role in keeping our Sun shining.
But what does the weak force do? Well … that requires getting a little into the weeds of particle physics. Here goes nothing! We mentioned quarks earlier — these are tiny particles that, among other things, make up protons and neutrons. There are six types of quarks, but the two that make up protons and neutrons are called up and down quarks. The weak force changes one quark type into another. This causes neutrons to decay into protons (or the other way around) while releasing electrons and ghostly particles called neutrinos.
So for example, the weak force can turn a down quark in a neutron into an up quark, which will turn that neutron into a proton. If that neutron is in an atom’s nucleus, the electric charge of the nucleus changes. That tiny change turns the atom into a different element! Such reactions are happening all the time in our Sun, giving it the energy to shine.
The weak force might just help to keep you in the (sun)light.
All four of these forces run strong in the universe. They flow between all things and keep our universe in balance. Without them, we’d be doomed. But these forces will be with you. Always.

Method of accelerating the maturation of stem cells to form neurons discovered
Very little is still known about how neurons can be generated from stem cells. Researchers at the University Medical Center of Johannes Gutenberg University Mainz (JGU) have now developed a promising technique that will facilitate the differentiation of stem cells into neurons. This even enables them to accelerate the maturation process. For this purpose, they use a hydrogel to create a stiffness-controlled scaffold for artificial brain tissue that furthermore stimulates the development of neurons. The team subsequently plans to investigate how hydrogel-based biomaterials can be injected into severely damaged brain regions in order to improve brain tissue regeneration. Over the long term it is hoped it will be possible to provide help to stroke victims or those suffering from neurodegenerative diseases. The Mainz-based researchers have recently published their findings in the leading journal Stem Cell Reports.
“We used a new type of biomaterial in our experiments. Its structure and consistency can be modified to create properties similar to those of the human brain. It has the same elasticity as cerebral tissue and has special adhesive molecules that promote neuronal fate and neurogenesis, thus creating the ideal conditions for neurogenesis,” said Dr. Marcelo Salierno of the Institute of Physiological Chemistry at the Mainz University Medical Center, who is heading up the project. Salierno is a member of Professor Benedikt Berninger’s research team at the Institute of Physiological Chemistry.
In addition to the physiological proteins present in the brain, the hydrogel also contains the synthetic adhesive molecule IKVAV. The resulting biomaterial accelerates the process and increases the chances to generate neurons from neural stem cells. Salierno was able to demonstrate this effect in his experiments. “The combination of the two factors, i.e., neural surface adhesion and the brain-like elasticity of the material, foster the controlled development of stem cells into neurons,” added Salierno.
The series of experiments undertaken by the scientists working with Dr. Marcelo Salierno were initially performed in vitro. As a result, the researchers were able to observe how the new biomaterial interacts with human cells and how stem cells differentiate into neural cells. “The next step would be to modify the hydrogel so that it would be possible to inject it into damaged brain regions,” explained Salierno. “These are the very first steps along a very ambitious path but we believe that in the near future those suffering from neuronal degeneration will benefit from our discovery.”
