New study reveals how human astroviruses bind to humans cells and paves the way for new therapies and vaccines Human astroviruses are a leading viral cause of the stomach bug—think vomiting, diarrhea, and fever. It often impacts young children and older adults, leading to vicious cycles of sickness and malnutrition, particularly for those in low and middle income countries. It’s very commonly found in wastewater studies, meaning it’s frequently circulating in communities. As of now, there are no vaccines for…
A new sensor on the submersible Alvin discovered reactive oxygen species for the first time in deep-sea corals, broadening our understanding of fundamental coral physiology. Just like us, corals breathe in oxygen and eat organic carbon. And just like us, as a byproduct of converting energy and oxygen in the body, corals produce reactive oxygen species (ROS), a family of chemical compounds that are naturally made by cells during cell division, while fighting off pathogens, and performing other physiological functions….
Titanium hip implants do not last forever — they gradually loosen, sooner or later losing their hold on the bone as it recedes over time. Researchers at the Fraunhofer IAP have been working alongside the Fraunhofer IGB and the Fraunhofer CMI to develop a tissue adhesive that can help avoid early replacement of prostheses in the future. The biomimetic, antimicrobial material is applied to the titanium surface of the implant, which then connects with the bone and naturally adheres to…
Farmland often harbors a multitude of pathogens which attack plants and reduce yields. A Swiss research team has now shown that inoculating the soil with mycorrhizal fungi can help maintain or even improve yields without the use of additional fertilizers or pesticides. In a large-scale field trial, plant yield increased by up to 40 percent. Intensive use of fertilizers and pesticides on fields reduces biodiversity and pollutes the environment. There is therefore great interest in finding sustainable ways to protect…
Anne Bentley, chemistry professor at Lewis & Clark College, has developed an innovative way to teach nanoscience, using 3D-printed models that make the unseen visible. Nanoparticles are super tiny―as small as one nanometer, or one billionth of a meter―and are of keen interest to materials scientists for their unique physical and chemical properties. They cannot be detected by the naked eye and require a highly specialized electron microscope to be seen. In fact, advancements in imaging technologies through the 1990s…
A simple-to-apply, needle-free vaccine patch is being developed to protect people from the potentially deadly mosquito-borne Zika virus. A prototype using The University of Queensland-developed and Vaxxas-commercialised high-density microarray patch (HD-MAP) has delivered a University of Adelaide-developed vaccine and elicited an effective immune response to Zika virus in mice. UQ alum and Vaxxas researcher Dr Danushka Wijesundara said Zika virus was a risk to people across the Pacific, Southeast Asia, India, Africa and South and Central America. “We can change the way…
Genomic studies shed light on the origins of bee venom. Bees, wasps and ants belong to the Hymenoptera order and inject a whole cocktail of venomous ingredients when they sting. Despite their tremendous ecological and economic importance, little was previously known about the origins of their venom. Through extensive genomic studies, a team of researchers led by Dr. Björn von Reumont from Goethe University Frankfurt has now discovered that typical venomous components were already present in the earliest ancestors of…
Heidelberg scientists unveil genetic programmes controlling the development of cellular diversity in the cerebellum of humans and other mammals. The evolution of higher cognitive functions in human beings has so far mostly been linked to the expansion of the neocortex – a region of the brain that is responsible, inter alia, for conscious thought, movement and sensory perception. Researchers are increasingly realising, however, that the “little brain” or cerebellum also expanded during evolution and probably contributes to the capacities unique…
TUM researchers develop rapid test for severe infections. Researchers at the Technical University of Munich (TUM) have developed a method for assessing the number and structure of aggregated blood platelets (or thrombocytes) that can potentially help quantify the risk of a severe COVID-19 infection. As a result, they have identified a predictive biomarker for the seriousness of a COVID-19 infection. This will allow physicians to adjust treatment at an early stage. The researchers used a method from image-based flow cytometry…
The multicellular bots move around and help heal “wounds” created in cultured neurons. Researchers at Tufts University and Harvard University’s Wyss Institute have created tiny biological robots that they call Anthrobots from human tracheal cells that can move across a surface and have been found to encourage the growth of neurons across a region of damage in a lab dish. The multicellular robots, ranging in size from the width of a human hair to the point of a sharpened pencil,…
Microgels form a thin protective shell around a droplet until the temperature rises above 32 degrees. Then the microgels shrink and the droplet dissolves in the surrounding liquid. A study by researchers from the University of Gothenburg now reveals the underlying mechanism behind this process. The discovery could revolutionise methods of targeting medicines to specific locations within the body. Emulsions consist of numerous droplets that are present in a liquid without dissolving and mixing with the liquid. For example, milk…

These new features are part of the expansion of the Company’s end-to-end Pharma.AI platform and include chat functionality, off-target screening tools, enhanced knowledge graphs and more. They represent major steps forward in the advancement of AI drug discovery. The company is an early innovator in generative chemistry and biology…
What happens when the vaginal microbiome attacks. UC San Diego study begins to explain why a common and seemingly benign condition of the vaginal microbiome is linked to pregnancy loss, preterm birth and other health complications. Bacterial vaginosis is a common condition in which the natural microbiome of the vagina falls out of balance, sometimes leading to complications in sexual and reproductive health. But exactly how these bacterial populations disrupt vaginal health has remained unclear. Researchers at University of California…
New research being presented this week at the annual meeting of the Radiological Society of North America (RSNA) links soccer heading – where players hit the ball with their head – to a measurable decline in the microstructure and function of the brain over a two-year period. “There is enormous worldwide concern for brain injury in general and in the potential for soccer heading to cause long-term adverse brain effects in particular,” said senior author Michael L. Lipton, M.D., Ph.D.,…
…with sensing, imaging technology. A research poster dated Dec. 9, 2015, hangs just outside Nicole Hashemi’s Iowa State University laboratory. It introduces a major project for Hashemi and her research group. And it’s evidence that scientific persistence sometimes equals scientific advancement. Hashemi, an associate professor of mechanical engineering, and her students have been working all these years to develop a “placenta-on-a-chip.” In this case that’s a thin, rectangular, clear, polymer block with two tiny microchannels – just millionths of a…
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”. Our bodies are transversed by millions of nerve fibres that transmit information. This allows us to do things like control muscles and perceive sensory impressions. Peripheral nerves,…
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. This causes defects in head and tail structure of…
