Brain scans of former NFL players show lasting impact of collision sports New research from Johns Hopkins Medicine adds to a growing stack of evidence that collision sports including football, soccer, and boxing may lead to dementia and other forms of cognitive disorders Kristen Crocker / Published Nov 29, 2023 In a new study using brain scans of former NFL athletes, Johns Hopkins Medicine researchers say they found high levels of a repair protein present long after a traumatic brain injury such as a concussion takes place.

AI breakthrough may lead to highly personalized medicine in the treatment of serious diseases Machine learning is now helping researchers analyze the makeup of unfamiliar cells, which could lead to more personalized medicine in the treatment of cancer and other serious diseases. Researchers at the University of Waterloo developed GraphNovo, a new program that provides a more accurate understanding of the peptide sequences in cells.

Efficient removal of abnormal myelin allows survival of nerve fibers targeted by adaptive immune cells, according to a novel study by scientists of the University Hospital Würzburg. Myelin is an insulating sheath around axons - the processes connecting nerve cells - that is mostly composed of lipids and proteins.

Researchers led by Göttingen University determine factors for chemical development in crater lakes on Earth In southern Germany just north of the Danube, there lies a large circular depression between the hilly surroundings: the Nördlinger Ries. Almost 15 million years ago, an asteroid struck this spot.

Bonn researchers uncover contribution of Cylicin proteins to male fertility For successful fertilization, sperm should move forward rapidly and be shaped correctly. The unique structure of the sperm cells forms during spermiogenesis. Now, researchers from the University Hospital Bonn (UKB) and the Transdisciplinary Research Unit "Life & Health" at the University of Bonn have found that fertility problems in both mice and humans can be caused by loss of so-called cylicines.

Researchers have identified a new way to screen genes that cause several different types of cancers to grow, identifying particularly promising targets for precision oncology in oral and esophageal squamous cancers. The study, published in this month's issue of Cell Reports , used 3-dimensional models of organ tissues called organoids to identify and test potential gene targets from The Cancer Genome Atlas.

The return of bluefin tuna to Northern European waters is a conservation success story, but rising sea temperatures in their Mediterranean nursery grounds mean this recovery may be short-lived, according to new research led by the University of Southampton. Temperatures expected in the Mediterranean within the next 50 years are expected to drive juvenile tuna out of the Mediterranean, where they may be accidentally caught in existing sardine and anchovy fisheries - requiring fishery managers to adapt their methods to allow tuna nurseries to establish.

Study of two million individuals' psychological well-being from 2005 to 2022 in 168 countries, in relation to country-level internet-use and mobile broadband statistics Negative and positive experiences had increased on average, but little to no evidence suggesting (mobile) internet use was associated with these changes Links between internet adoption and psychological well-being are small at most, despite popular assumptions about the negative

The world's first transatlantic flight run on 100% sustainable aviation fuel is taking off today from London Heathrow, bound for New York. The Virgin Atlantic Boeing 787 flight, which is taking off on 28 November 2023 from London Heathrow (LHR) to New York John F Kennedy Airport (JFK), is the first to showcase the feasibility of flying on 100% sustainable aviation fuel (SAF) over such a distance.

In a study published in the journal "Scientific Reports," researchers from the Senckenberg Centre for Human Evolution and Palaeoenvironment (SHEP) at the University of Tübingen show that early humans of the Middle Paleolithic had a more varied diet than previously assumed. The analysis of a site in the Zagros Mountains in Iran reveals that around 81,000 to 45,000 years ago, the local hominins hunted ungulates as well as tortoises and carnivores.

Damage to the body's peripheral nerves can cause pain and movement disorders. Researchers at the Leipzig University have recently investigated how damaged nerves can regenerate better. They found that fat tissue strongly supports the Schwann cells needed for repair during the healing process. The results were published in the renowned journal "Cell Metabolism".

Computing with a combination of light and chargeless excitons could beat heat losses and more, but excitons need new modes of transport Study: Enhanced Exciton-Drift Transport through Suppressed Diffusion in One-Dimensional Guides (DOI: 10.1021/acsnano.3c04870) A new kind of "wire- for moving excitons, developed at the University of Michigan, could help enable a new class of devices, perhaps including room temperature quantum computers.

Antimicrobial hospital curtains Hospital germs and pathogens are not always transmitted directly from person to person. They can also spread via germ-contaminated surfaces and objects. researchers, together with the chemical company BASF, Spiez Laboratory and the Technical University of Berlin, have now developed coated textiles that inhibit or even kill pathogens.

McGill researchers explore the power of imagination, showing how a shift in thinking can make humans more caring In a world grappling with deep-seated division and social upheaval, empathy has become more critical than ever. But science suggests when it comes to evoking empathy, our imagination is more powerful than we previously thought.

The mental health of Australians has been declining since around 2010 and this is seen in earlier generations, not just the youths of Gen Z, according to a new study led by the University of Sydney. It's widely agreed that young people's mental health has declined in developed countries in recent years.

Publication of the Chemistry Laboratory in the journal ACS Catalysis on November 9, 2023. Communication of CNRS Chemistry on November 27, 2023. Producing dihydrogen by electrolysis of water requires rare and therefore expensive catalysts. They could be replaced by another molybdenum-based catalyst, much more abundant but currently less efficient.

Nearly a third of the world's mine tailings are stored within or near protected conservation areas, University of Queensland research has found. A study led by UQ's Bora Aska , from the Sustainable Minerals Institute and School of the Environment, said these waste facilities pose an enormous risk to some of earth's most precious species and landscapes.

Researchers at Bath have developed a way of joining up the head and tail of a protein, making it more stable and easier to get into cells. Published on Tuesday 28 November 2023 Last updated on Tuesday 28 November 2023 Scientists at the University of Bath have used nature as inspiration in developing a new tool that will help researchers develop new pharmaceutical treatments in a cleaner, greener, and less expensive way.

In the search for new particles and forces in nature, physicists are on the hunt for behaviors within atoms and molecules that are forbidden by the tried-and-true Standard Model of particle physics. Any deviations from this model could indicate what physicists affectionately refer to as "new physics." Caltech assistant professor of physics Nick Hutzler and his group are in pursuit of specific kinds of deviations that would help solve the mystery of why there is so much matter in our universe.

Massachusetts Institute of Technology Using fluorescent labels that switch on and off, MIT engineers can study how molecules in a cell interact to control the cell's behavior. Living cells are bombarded with many kinds of incoming molecular signal that influence their behavior. Being able to measure those signals and how cells respond to them through downstream molecular signaling networks could help scientists learn much more about how cells work, including what happens as they age or become diseased.
