First high-resolution image of thick filaments of muscle cells
An international team, led by Stefan Raunser, Director at the Max Planck Institute of Molecular Physiology in Dortmund, in collaboration with Mathias Gautel at King's College London, has successfully obtained the world's first high-resolution 3D image of the thick filament in its natural cellular environment, utilizing a cutting-edge technique known as electron cryo-tomography.

Collective intelligence makes fewer diagnostic errors
Researchers from the Max Planck Institute for Human Development, the Institute for Cognitive Sciences and Technologies, and the Norwegian University of Science and Technology developed a collective intelligence approach to increase the accuracy of medical diagnoses. An estimated 250,000 people die from preventable medical errors in the U.S. each year.

Sex or regeneration
Why are so few species able to regenerate damaged or missing body parts, even though regeneration might seem an obvious survival advantage? Researchers at the Max Planck Institute for Multidisciplinary Sciences in Göttingen, Germany, and colleagues have now found a possible explanation in planarian flatworms.

Cardiac regeneration becomes possible
In mice reprogramming of energy metabolism restores cardiac function after infarction After birth, the human heart loses its regenerative capacity almost completely. Damage to the heart muscle, e.g. due to a heart attack, therefore usually leads to a permanent loss of function in adults.

The menstrual rhythm of the brain
In the female brain, regions important for memory and perception are remodeled in the course of the menstrual cycle Central learning and memory hubs change in response to sex hormones. A new study in Nature Mental Health by Rachel Zsido and Julia Sacher of the Max Planck Institute for Human Cognitive and Brain Sciences and the University Clinic in Leipzig, Germany, links rhythmic oscillations in ovarian hormone levels in women during the menstrual cycle to changes in brain structure.

Temporal change in risk tolerance around payday
People living in poverty often struggle from payday to payday. Those who receive government assistance, such as welfare or pensions, must manage scarce resources to make ends meet until the next payment. Researchers from Kobe University, the Max Planck Institute for Demographic Research, Toyo University, and Simon Fraser University have studied how people's willingness to take risks changes before and after payday.

Vision in the brain - hardwired for action
Brain circuits for vision develop without any kind of input from the retina in zebrafish Animals possess specialized networks of neurons in the brain that receive signals about the outside world from the retina and respond by initiating appropriate behavior. Researchers at the Max Planck Institute for Biological Intelligence studied a genetic mutation in zebrafish that eliminates all connections between retina and brain throughout development.

Hiccups in the starry nursery
Before the light comes on and a new star shines, enough gas and dust must accumulate in a very small space for a star's energy source, nuclear fusion, to ignite. This by no means happens at rest. Matter swirls around, and before the star sees the light of day, violent birth labour is not uncommon. The new James Webb Space Telescope has turned its lens on such a spectacle, which reveals itself in unprecedented detail.

Larger brain area for language
Language is one aspect that makes us human. The ability to produce an infinite number of utterances based on the words in the mental lexicon and a small number of syntactic rules is unique to humans. Other animals can learn words or calls and communicate, but the language ability of humans is unique.

Animals may be the best monitors of global climate change
Carrying small sensors, they could be the most sensitive and informative weather instruments of all The world's scientists rely on an elaborate network of satellites, ocean buoys, weather stations, and balloons to help predict the weather and assess the impact of global climate change across land, air, and sea.

Efficient training for artificial intelligence
New physics-based self-learning machines could replace the current artificial neural networks and save energy Artifical intelligence not only affords impressive performance, but also creates significant demand for energy. The more demanding the tasks for which it is trained, the more energy it consumes.

Anti-obesity drug improves associative learning in people with obesity
Obesity leads to altered energy metabolism and reduced insulin sensitivity of cells. The so-called "anti-obesity drugs" are increasingly used to treat obesity and have caused tremendous interest, especially in the USA. Researchers at the Max Planck Institute for Metabolism Research in Cologne, Germany, have now shown in people with obesity that reduced insulin sensitivity affects learning of sensory associations.

Electricity driving life
Using a metabolic pathway, energy-rich resources can be produced via the power of electricity When nature performs chemical reactions to create energy-rich compounds from simple molecules, it requires energy. So far, it has not been possible to use human-made electricity to drive these biochemical processes.

The evolution of complex grammars
A new study shows that changes in grammatical complexity are not shaped by social environments Many linguists have proposed that languages spoken by numerous non-native speakers tend to have simpler grammars. A new study led by researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig challenges this claim.

Ötzi: dark skin, bald head, Anatolian ancestry
Research team used advanced sequencing technology to analyze Ötzi's genome to obtain a more accurate picture of the Iceman's appearance and genetic origins Ötzi's genome was decoded for the first time more than ten years ago. This was also the first time the genome of a mummy had been sequenced. The results provided important insights into the genetic makeup of prehistoric Europeans.

An experiment, conducted on wild orangutans, uncovers the conditions that spark curiosity Humans like to discover. Presented with something we've never seen before, most of us will be compelled to explore and learn more about it. The same can't exactly be said for our closest living relatives - the great apes.

IT security in a comic
Researchers of the Max Planck Institute for Security and Privacy participate in innovative science communication In an era of increasing digitalisation, IT security is becoming an increasingly important issue, not only for large organisations but also for individuals. However, the complex science behind it often makes this abstract topic inaccessible.

Personality traits and the likelihood of childbearing
The decline in birth rates in many industrialized countries since the mid-1950s is partly due to a change in values. People decide more individually whether they want to have children or not. Steffen Peters of the Max Planck Institute for Demographic Research has investigated the role played by personality traits such as empathy or extroversion.

Pills from the 3D printer
Pills could soon be produced in shapes that resemble design objects. And this would not be just an aesthetic gimmick, but would serve to release active medical ingredients in the body in a controlled manner. A group of computer scientists from the Max Planck Institute for Informatics in Saarbrücken and the University of California at Davis have developed a process that uses a combination of computation and 3D printing to produce tablets that dissolve in liquids over a specified period of time.

Fonts in transition
Throughout history, people have created different sign systems that correspond to the specifics of each language. The scripts have evolved in the process. Today, it is no longer possible to trace exactly how, since the development has usually been completed thousands of years ago. This is not the case with the West African Vai script, which did not come into being until the 1830s.
