Does the exoplanet Trappist-1 b have an atmosphere after all?
Does the exoplanet Trappist-1 b have an atmosphere after all?
New observations with the James Webb Space Telescope no longer rule out the presence of an atmosphere around the Earth-sized rocky planet. However, a geologically active planet also explains the data. Recent measurements with the James Webb Space Telescope (JWST) cast doubt on the current understanding of the exoplanet Trappist-1 b-s nature.

Bulwark in the fight against viruses - new bacterial immune system decoded
International research team describes for the first time the structure and function of the Zorya system, a highly specialized antiviral protection mechanism against bacteria. Bacteria are constantly infected by viruses, so-called phages, which use the bacteria as host cells. However, in the course of evolution, bacteria have developed a variety of strategies to protect themselves from these attacks.

How could this happen? On the trail of the mega earthquake
How did the Fukushima disaster occur in 2011 and how can we better understand geological processes in order to protect coastal infrastructure in the long term? These questions surrounding the Tohoku earthquake are the focus of an expedition involving a scientist from RWTH Aachen University. The Tohoku earthquake occurred off the east coast of Japan on March 3, 2011.

Oldest modern human genomes sequenced
Oldest modern human genomes sequenced
Genomes of seven early Europeans show they belonged to a small, isolated group that had recently mixed with Neandertals but left no present-day descendants Few genomes have been sequenced from early modern humans, who first arrived in Europe when the region was already inhabited by Neandertals. An international team led by researchers at the Max Planck Institute for Evolutionary Anthropology has now sequenced the oldest modern human genomes to date.

New timeline for Neandertal gene flow event
New timeline for Neandertal gene flow event
Scientists unravel timing and impact of Neandertal gene flow into early modern humans Ancient DNA research suggests that our non-African ancestors mixed with Neandertals about 50,000 years ago, resulting in one to two percent Neandertal DNA in non-African modern humans. In a study of 300 genomes, researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig and the University of California, Berkeley found that this likely occurred in a single instance about 47,000 years ago, suggesting a human migration out of Africa no later than 43,500 years ago.

Intelligence requires the whole brain
Intelligence requires the whole brain
A team of Würzburg neuroscientists investigates communication pathways in the brain and predicts intelligence. A new study approach uses machine learning to improve our conceptual understanding of intelligence. The human brain is the central control organ of our body. It processes sensory information and enables us, among other things, to form thoughts, make decisions and store knowledge.

Contactless diagnosis: research team develops innovative measurement technology to determine vital signs A research team from TU Ilmenau and the Faculty of Medicine at the University of Duisburg-Essen (UDE) has jointly developed an optical measurement system that can be used to monitor the health status of chronically ill or highly contagious people using vital parameters such as body temperature, respiratory rate or oxygen saturation without contact.

New findings on blood clotting
New findings on blood clotting
Bonn researchers decipher structure of coagulation factor XIII using cryo-electron microscopy A deficiency in blood plasma coagulation factor XIII leads to a disruption in the cross-linking of fibrin, the "glue" in blood coagulation. The enzyme therefore plays an essential role in blood clotting. Researchers at the University Hospital Bonn (UKB) and the University of Bonn, together with Thermo Fisher Scientific in the Netherlands, deciphered the previously unknown structure of the Factor XIII complex using cryo-electron microscopy (cryo-EM), even at the atomic level.

Does Leaning Left Politically Make You a More Prosocial Person?
A comprehensive study conducted by the Max Planck Institute for the Study of Crime, Security and Law in Freiburg im Breisgau, Germany, now found that while there is a connection between political orientation and prosociality, it is weaker than previously assumed. It is often assumed that people who hold left-wing political beliefs have stronger prosocial traits and are more altruistic than those who support right-wing parties.

Desert ants use the polarity of the geomagnetic field for navigation
Desert ants use the polarity of the geomagnetic field for navigation
Many animals orient themselves using their sense of magnetism. However, this can be based on different physical mechanisms. A research team from Oldenburg and Würzburg has now investigated the navigation of the desert ant. Desert ants of the Cataglyphis nodus species use the Earth's magnetic field for spatial orientation, but these tiny insects rely on a different component of the field than other insects, a research team led by Dr Pauline Fleischmann from the University of Oldenburg reports in the journal Current Biology.

Adaptation mechanisms of microscopic algae
Adaptation mechanisms of microscopic algae
Researchers from the University of Jena and the Leibniz Institutes in Jena have published new findings on the adaptability of the microalgae Chlamydomonas reinhardtii. The interdisciplinary study, largely carried out by researchers from the Cluster of Excellence -Balance of the Microverse-, shows how the tiny green alga can adapt its shape and metabolism under natural conditions without changing its genome.

Parrots imitate parrots
Parrots imitate parrots
Blue-throated macaws, a critically endangered parrot species, have demonstrated automatic imitation of intransitive (goal-less) actions-a phenomenon previously documented only in humans. In a study conducted by an international team of researchers from the Max Planck Institute for Biological Intelligence, in collaboration with the Loro Parque Fundación, scientists reveal that macaws involuntarily copy intransitive movements.

A Blueprint for the Brain’s Circadian Clock
Circadian clocks control physiological processes and behavior in virtually all living organisms. Now an international research team led by researchers from the University of Würzburg has created a detailed map of the internal clock in the brain of the fruit fly. All animals including humans are subject to daily rhythms in their activity and sleep, hunger, metabolism, and reproduction.

Milestone in Defining Electrical Units
Scientists at the University of Würzburg and the German national metrology institute (PTB) have carried out an experiment that realizes a new kind of quantum standard of resistance. It's based on the Quantum Anomalous Hall Effect. The precise measurement of electrical resistance is essential in industrial production or electronics - for example, in the manufacture of high-tech sensors, microchips and flight controls.

Protecting the world’s bonobo stronghold
A twenty-year study in Congo's largest protected park confirms that rangers are effective in preserving endangered bonobos Scientists now know how many bonobos live in one of the largest pristine tropical forests, a place believed to be the world's stronghold for the endangered species. The research, conducted over two decades by a team of 48 scientists, estimates that between 8,000 to 18,000 adult bonobos inhabit Salonga National Park in the DRC.
