Double Trouble: Infamous ’Eagle Killer’ Bacterium Produces Not One, But Two Toxins
Study headed by Professor Timo Niedermeyer published in the journal "Proceedings of the National Academy of Sciences" The cyanobacterium Aetokthonos hydrillicola produces not just one, but two highly potent toxins. In the latest issue of the journal Proceedings of the National Academy of Sciences (PNAS), an international team led by Martin Luther University Halle-Wittenberg (MLU) and Freie Universität Berlin describes the second toxin, which had remained elusive until now.

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.
Biodiversity is greatest in the tropics. That fact that it is hot and humid there plays an important role. However, climate alone cannot explain the global biodiversity patterns well. Researchers at the Swiss Federal Institute for Forest, Snow and Landscape Research have now tackled this old problem from a completely different angle - and identified a new, doubly important reason for high tropical diversity.
Concussed, me? It’s nothing
If they've already had a concussion before, university athletes are less likely to report symptoms of a new one when the symptoms are less severe, an UdeM study suggests. University athletes who have already suffered a sport-related concussion are less likely to report symptoms of a new concussion if they consider them to be less serious than their previous ones.

By Philipp Jarke Photovoltaic cells made of organic materials are light and flexible, which is why they are considered very promising. An international research network led by TU Graz is now aiming to increase the stability of the materials. Solar cells made of silicon have been around for 70 years. Organic solar cells, on the other hand, are quite new, but open up new possibilities for emission-free electricity production.
New simulations shed light on origins of Saturn’s rings and icy Moons
A new series of supercomputer simulations has offered an answer to the mystery of the origins of Saturn's rings - one that involves a massive collision in the recent history of the 4.5 billion-year-old Solar System.

Problem drinking linked to alcohol on social media
A University of Queensland study highlights a direct link between young people's exposure to alcohol-related social media content and problem drinking. The study led by PhD candidate Brandon (Hsu-Chen) Cheng from UQ's Australian National Centre for Youth Substance Use Research examined results from 30 international studies of more than 19,000 people aged 24 and younger.

Through an innovative project in Sri Lanka, an EPFL researcher and a Sri Lankan researcher have demonstrated that construction practices in transition economies can operate more efficiently, sustainably and responsibly.
A team of scientists from Bath and Bristol have identified a protein fragment that could be a template for new therapeutics for dementia. Published on Wednesday 27 September 2023 Last updated on Wednesday 27 September 2023 Scientists have identified a molecule that can prevent tangling of a brain protein that is linked to diseases such as Parkinson's.
Protein that drives liver damage could be a new target for treatment
Yale researchers have identified a protein that drives symptoms of severe liver disease and may be a target for treatment in the future. A severe form of fatty liver disease called nonalcoholic steatohepatitis (NASH) is the leading cause of liver transplantation, but there are few treatment options and currently no medications.

Scientists using space-based radar found that land in New York City is sinking at varying rates from human and natural factors. A few spots are rising. Parts of the New York City metropolitan area are sinking and rising at different rates due to factors ranging from land-use practices to long-lost glaciers, scientists have found.
MIT engineers and collaborators developed a solar-powered device that avoids salt-clogging issues of other designs. Engineers at MIT and in China are aiming to turn seawater into drinking water with a completely passive device that is inspired by the ocean, and powered by the sun. In a paper appearing today in the journal Joule, the team outlines the design for a new solar desalination system that takes in saltwater and heats it with natural sunlight.

An advance in cryo-EM could be a significant boon for research on potential cancer therapies Science + Technology An advance in cryo-EM could be a significant boon for research on potential cancer therapies September 26, 2023 Key takeaways A technology called cryo-electron microscopy, or cryo-EM, enables scientists to see the atomic structure of biological molecules in high resolution.
Imperial and US medical technology company MediBeacon have partnered to advance a non-invasive method of assessing intestinal health. In healthy people, the wall of the intestine forms a barrier between the contents of the gut and the rest of the body, with only the nutrients produced by digestion passing through.

Organic dyes accelerate transport of buffered solar energy The sun sends enormous amounts of energy to the earth. Nevertheless, some of it is lost in solar cells. This is an obstacle in the use of organic solar cells, especially for those viable in innovative applications. A key factor in increasing their performance: Improved transport of the solar energy stored within the material.
Invasive animal and plant species are affecting biodiversity worldwide. To better understand the specific dispersal processes during a biological invasion, researchers from the University of Potsdam and Trinity College Dublin studied an acute invasion. More than 100 years ago, red-backed voles, a Eurasian vole species, were accidentally introduced to the west coast of Ireland and have been spreading continuously ever since.
Scientists show that it is possible to make a femtosecond laser that fits in the palm of one's hand using a glass substrate. Is it possible to make a femtosecond laser entirely out of glass? That's the rabbit hole that Yves Bellouard , head of EPFL's Galatea Laboratory, went down after years of spending hours - and hours - aligning femtosecond lasers for lab experiments.
How concepts enter the brain and the role language plays in this process
Study on the connection between language and thinking by neuroscientists at Freie Universität Berlin published The influence of language on human thinking may be stronger than previously thought. This is the result of a new study by the language, cognition, and neuroscientist Friedemann Pulvermüller and his team from the Laboratory for Brain and Language Research at Freie Universität Berlin.
