When someone begins to study the evolution of the universe and the laws of physics, one easily comes to wonder how strange it is that humans and life exist, and we are able to observe the universe. If the laws and constants of nature were just a little bit different, the occurrence of life is unthinkable. However, we can state that we are here, and this raises a number of other issues, such as: Has the universe always been able to sustain life? Will the universe continue to sustain the existence of life in the future ? Are we just one of many universes that exist in parallel?
Science Journalist Jens Degett from Science Stories talks to Professor Niels Obers, Director of the Nordic Institute for Theoretical Physics (NORDITA) and professor at the Niels Bohr Institute in Copenhagen, to try and get to the bottom of the matter. This podcast is a continuation of their conversation in a former story "Big Bang challenged by Conformal Cyclic Cosmology". -
We are used to think about the universe as a structure which started with a Big Bang and then expanded. Sir Roger Penrose, who received the 2020 Nobel Prize in Physics, has developed an alternative theory of the universe based on Einstein’s Theory of General Relativity which is called "Conformal Cyclic Cosmology". In this new model we don’t have one single Big Bang, but an iteration of infinite cycles (or aeons) of expansion and cooling, each beginning with a “big bang” and ending in a “big crunch”.
Science Journalist Jens Degett interviews Professor Niels Obers, Director of the Nordic Institute for Theoretical Physics (NORDITA) and professor at the Niels Bohr Institute in Copenhagen, on Roger Penrose’s theory and how much evidence is needed in order to change the general view of a central paradigm which is written in our school textbooks. What if Penrose is right? What consequences or perspectives will it have for us? -

This podcast on our living universe is recorded in Danish. We will try to make an English transcription as soon as we we can get a suitable transcription tool.
Vores levende univers
Der sker i disse år så meget inden for forskning især inden for biovidenskaberne. Vi studerer på livet løs hvordan liv fungerer, men hvad liv egentligt er, det er stadig et godt spørgsmål. Hvis man føler sig hægtet af, så er der en god anledning til at få et overblik over emnet lige nu - for Gunver Lystbæk Vestergård har skrevet en bog, som udkommer på Peoples Press i disse dage med titlen
Vores Levende Univers - videnskabens søgen efter rumvæsener og alt livs oprindelse.
Hør videnskabsjournalist Jens Degett interviewe forfatter og videnskabsjournalist Gunver Lystbæk Vestergård om hendes bog og hvad der i øvrigt sker med vores erkendelse af liv i universet. -
This Is an original interview with one of the great Nobel Laureate who is talking about the development of life in the universe.

One of the most powerful and advanced laser research institutions in the world is situated in Hungary. It is called the Extreme Light Infrastructure (ELI) The Lasers of ELI can generate light pulses so bright that they can capture femtosecond and attosecond events in the molecular and atomic range. This can be used in a number of very different research disciplines from medicine and life science to climate and material research. More than 600 researchers work here, but many more are visiting from all over the world.

More than 100 years ago August Krogh received the Nobel Prize for showing how oxygen is transported from the lungs through the blood into the small capillaries in the muscles. Details of the mechanism and how it is regulated are still central topics of research a hundred years after and understanding respiration is still a matter of life or death.
In this interview science journalist Jens Degett had the opportunity to talk to, one of the world's leading physiologists professor Christopher Ellis from the University of Western Ontario (Canada) about how August Krogh's 1920 Nobel Prize greatly influences physiological research even 100 years later.
In addition to Nobel Prize class research, August Krogh founded one of the first biomedical companies in Denmark. The company would later become Novo Nordisk, which is now among the world's largest manufacturers of biomedicine and insulin.

DNA and RNA sequence analysis enable researchers to form a total overview of which species of microorganisms and parasites live with humans, animals and plants.
It is not just in our gut where microorganisms are playing a role in our digestion. Also on the skin and all mucous membranes, in the mouth and all the way down into the hair follicles, we live together with parasites and microorganisms which help to shape our lives and our development.
This knowledge makes it possible to see organisms in a far more holistic perspective, which provides a far better understanding of the factors that have evolutionarily shaped the species as they now appear in nature.
In this podcast, Science Journalist Jens Degett talks to Professor Marcus Thomas Pius Gilbert from the Center for Evolutionary Hologenomics (CEH) at the University of Copenhagen. The center has recently received DKK 67.7 million from the Danish National Research Foundation.

Obesity, mobility, exercise and cancer are in the spotlight for researchers as there is an increasing amount of evidence pointing at the metabolic mechanisms which bind them together.
Associate Professor Lykke Sylow from the Department of Biomedical Sciences, Molecular Metabolism in Cancer and Ageing at the Health Faculty at University of Copenhagen Is being interviewed by science journalist Jens Degett from Science Stories about why it is important to be in a good shape, and all the benefits of exercise. -
The first quantum computer has arrived. The version of a quantum chip that recently came out of the Niels Bohr Institute in Copenhagen is now for sale, but it has already been sold out.
The price is cheap according to professor Peter Lodahl from Sparrow Quantum who has recently moved out of the old Niels Bohr Institute to the other side of the street. Not a big move but a quantum leap.
Science journalist Jens Degett is talking to Peter Lodahl in this podcast trying to understand what a quantum computer can do, how it works and what purpose it will serve. -
Professor Birger Lindberg Møller from Center for Synthetic Biology, Denmark, has always been impressed with the plant world and how plants can act as sun driven biochemical factories which can generate all the substances needed for growth and development of the plant. Plants can defend themselves with poison, they can signalise to each other and protect themselves against being eaten.
Humans have domesticated plants for thousands of years. With genetic engineering plants can be developed to produce a large amount of different substances from medicine to food and they can protect themselves better against environmental changes and diseases.
But the GMO approach has been controversial since the first GMO plants were launched in the 1990ies. Now Birger Lindberg Møller has another solution. Why not let the plants make their own natural mutations and select those which have the right genetic traits? It is possible to plant thousands of plants and select the very best with modern PCR screening.

Another year has passed - so welcome to the Science Stories New Year podcast 2025.
My name is Jens Degett and as tradition dictates, in this New Year's program, I play soundbites and tell stories about a selected sample of the last year's podcasts from Science Stories.
One of our limitations is language. Our podcast in Danish has by definition a very small audience. In the course of the years, we have a total number of podcasts plays on our own portal of more than 400.000 plays since we started. Listeners were mostly from Denmark, the Nordic countries and Greenland. I mentioned last year that we have an increasing audience around Europe and not least in Ohio-USA, and the rest of the world where our podcasts are listened to when they are published in English. As an experiment we have decided to make English the primary language of Science Stories. I cannot guarantee that all podcasts will be in English, but most of them will. If we find support for it we will switch permanently to English. An alternative solution could be that we publish in two languages with an AI translation.
In 2024 I received a Maria Leptin Science Journalism Fellowship. I spent two month at the Niels Bohr Institute in Copenhagen and one month at EMBL in Heidelberg.
There is a lot to talk about and I can really recommend to spend time with the researchers and get closer to the research institutions,
There is a lot to tell from 2024 so if you missed it you may go back and find the stories in our archive. Enjoy.

Researchers all over the world have tried for more than 25 years to make a new type of computer that can solve much more complex problems than traditional computers are capable of.
Professor Charles Marcus from the Niels Bohr Institute in Copenhagen is one of the leading researchers who have made major contributions to the development of quantum computers. He is giving a profound understanding about what quantum computing is and why it may, or may not be difficult to grasp.
He is interviewed about the state of the art of quantum computing by Science Journalist Jens Degett from Science Stories.
The interview was made in connection with the first Quantum Computing Applications in Chemical and Biochemical Engineering Workshop organized by the Danish Technical University (DTU) Department of Chemical Engineering, Knowledge Hub Zealand and the American Institute of Chemical Engineers (AIChE). -
Diabetes is about hormonal regulation of metabolism in the body. Apart from insulin there are many hormones, organs and receptors involved, but even if it is complicated to understand, it does not mean we should not talk about it or ask questions.
In connection with the commemoration of the discovery of insulin +100 years ago, Science Journalist Jens Degett interviewed one of the most experienced diabetes researchers in the world, Professor Sir Stephen O’Rahilly from Cambridge University.
The interview was recorded after an “August Krogh on Tour” lecture at the August Krogh Institute in Copenhagen.

Mitochondria are called the powerhouse of the cells. They convert nutrients into energy, and they may hold the key to reverse aging and cure a large number of diseases. This is why exercise is important. But, can science one day come up with a pill that can reverse the aging of mitochondria? How close are we to solve this fundamental discovery?
Professor Zhen Yan from University of Virginia was interviewed by Science Journalist Jens Degett from Science Stories. -
What can vi learn from sponges or other primitive animals who have no brain. at all? What are the advantage of spending a lot of energy on maintaining a brain and what can the study of animals with none or very primitive brains teach us about evolution of complex animals with large brains.
Professor Dr. Detlev Arendt is explaining to science journalist Jens Degett the advantage of having a small brain for some animals, and circadian rhythms studied in a small worm has evolved into a very special circadian control mechanism found in advanced animals.

Researchers at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, are taking the understanding of cell biology to a new level. Research group leader Alba Diz-Muñoz explains how shape or form, stiffness or rigidity, architecture and tension can make a big difference in your body’s reaction to physiology and disease.
It is not only hormone signals, DNA and biochemistry which determine the fate of a cell, an organ, or the whole body. Mechanical parameters have to be taken into consideration to understand why cells react to the environment as they do.
