Intestinal bacteria trigger postoperative complications
Previously, it was believed that a germ-free environment was the most critical factor in preventing postoperative infections. However, a recent study by Mercedes Gomez de Agüero's team from the Max Planck Research Group for Systems Immunology in Würzburg, Germany, in collaboration with the University Hospital of Bern, Switzerland, has revealed that the source of the danger is apparently entirely different: the patients' intestines.

Sensitive microorganisms in the stream benefit from forested banks
A forest is crucial for life in streams, particularly in the catchment area and in the headwaters. Eawag researcher Rebecca Oester has quantified the extent of this influence of forests in the riparian zone and found a significant effect, particularly for sensitive species. This work shows once again how closely terrestrial and aquatic habitats are linked.

Dieting: brain amplifies signal of hunger synapses
Many people who have dieted are familiar with the yo-yo effect: after the diet, the kilos are quickly put back on. Researchers from the Max Planck Institute for Metabolism Research and Harvard Medical School have now shown in mice that communication in the brain changes during a diet: The nerve cells that mediate the feeling of hunger receive stronger signals, so that the mice eat significantly more after the diet and gain weight more quickly.

Pathogen mapped for the first time – to understand evolution and potential treatments
Pathogen mapped for the first time - to understand evolution and potential treatments A parasite which has devastating impacts on agriculture and human health is the first pathogen to have its proteins located and mapped within its cells - providing clues to their function and helping to identify potential drug targets.

Gene therapy approach to boost ’cold shock protein’ in the brain without cooling protects mice against neurodegenerative disease
Scientists in Cambridge and Berlin have used a form of gene therapy to increase levels of the so-called -cold shock protein- in the brains of mice, protecting them against the potentially devastating impact of prion disease. Essentially, the cold shock protein enables the brain to protect itself - in this case, against the damage nerve cells in the brain during prion disease Giovanna Mallucci The discovery is a step towards harnessing the protective effects of cooling the brain to treat patients with acute brain injury and even to prevent dementias, such as Alzheimer-s.

Attack from the gut
Intestinal bacteria are often the trigger of complications after surgery. This is shown in a new study by research teams from Würzburg and Bern. A solution to this problem could come from the liver. Nearly 16 million operations were performed on inpatients in German hospitals in 2021. In Switzerland, the figure is around 1.1 million.

Alzheimer’s disease: new contrast agents
Publication of the Chemistry Laboratory in the journal Nanomedicine on March 17, 2023. Communication of the CNRS-INC on March 20, 2023. A consortium of European researchers led by two Lyon laboratories - the Chemistry Laboratory (CNRS/ENS de Lyon/Université Claude Bernard Lyon 1) and the Lyon Neuroscience Research Center ( CNRS/Claude Bernard Lyon 1 university/Jean Monnet University/Inserm) - is proposing a new "multi-technique" imaging agent (MRI, X-ray, fluorescence..) targeting amyloid-? (A?) plaques, the first pathological signs of Alzheimer's disease (AD).

Many genes are involved in ’resurrection’
Researchers from the Universities of Bonn and Michigan analyze the genome of a drought-tolerant plant Some plants can survive months without water, only to turn green again after a brief downpour. A recent study by the Universities of Bonn and Michigan shows that this is not due to a "miracle gene." Rather, this ability is a consequence of a whole network of genes, almost all of which are also present in more vulnerable varieties.

Honeycomb for winter protection
Smart heating saves bees from cold death Up to a third of bee colonies worldwide die over the winter, often due to excessively low temperatures. In cooperation with the Swiss École Polytechnique Fédérale de Lausanne (EPFL), the team of the Artificial Life Lab at the University of Graz has developed a high-tech honeycomb that can monitor the animals during the cold season and regulate the heat supply in the hive.

Beethoven’s genome
Scientists have sequenced the composer's genome using five genetically matching hair locks The study shows Beethoven was predisposed to liver disease, and infected with Hepatitis B, which - combined with his alcohol consumption - may have contributed to his death. Furthermore, DNA from modern relatives points to an extramarital 'event' in Beethoven's paternal line.

Eating more magnesium each day keeps dementia at bay
More magnesium in our daily diet leads to better brain health as we age, according to scientists from the Neuroimaging and Brain Lab at The Australian National University (ANU). The researchers say an increased intake of magnesium-rich foods such as spinach and nuts could also help reduce the risk of dementia, which is the second leading cause of death in Australia and the seventh biggest killer globally.

A Biofuel Breakthrough, Courtesy of Fungi
Adapted from a UC Santa Barbara news release by Sonia Fernandez It's a tough job, but someone's got to do it. In this case, the "job" is the breakdown of lignin, the structural molecule that gives plants strength and rigidity. One of the most abundant terrestrial polymers (large molecules made of repeating subunits called monomers) on Earth, lignin surrounds valuable plant fibers and other molecules that could be converted into biofuels and other commodity chemicals - if we could only get past that rigid plant cell wall.

How the brain’s ’internal compass’ works
Scientists have gained new insights into the part of the brain that gives us a sense of direction, by tracking neural activity with the latest advances in brain imaging techniques. The findings shed light on how the brain orients itself in changing environments - and even the processes that can go wrong with degenerative diseases like dementia, that leave people feeling lost and confused.

How vision begins
Researchers at the Paul Scherrer Institute PSI have deciphered the molecular processes that first occur in the eye when light hits the retina. The processes - which take only a fraction of a trillionth of a second - are essential for human sight. The study has now been published in the scientific journal Nature .

Changing temperatures increase pesticide risk to bees
Temperature influences how badly pesticides affect bees' behaviour, suggesting uncertain impacts under climate change, according to a new study. The findings indicate that future extreme temperature events under climate change could increase the impact of pesticides on bee populations and their pollination services.

Advanced brain imaging study hints at how DMT alters perception of reality
Scientists have gleaned new insights into how psychedelics alter conscious experience via their action on brain activity. In a study at Imperial College London, detailed brain imaging data from 20 healthy volunteers revealed how the potent psychedelic compound, DMT (dimethyltryptamine), alters brain function.

Can we learn without a brain?
Some animals do not need a brain to be able to learn. This is what Professor Simon Sprecher of the University of Freiburg has revealed in a study that has just been published. With his team, the biologist taught a sea anemone to adapt its behavior according to past experiences . We spontaneously associate the faculties of learning and memorization with the existence of a brain.

Base editing to correct mutation that causes rare immune deficiency
A condition called CD3 delta SCID is caused by a mutation in the CD3D gene, which prevents the production of the CD3 delta protein that is needed for the normal development of T cells from blood stem cells. UCLA researchers showed that a new genome editing technique called base editing can correct the mutation that causes CD3 delta SCID in blood stem cells and restore their ability to produce T cells.
