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…
The incidence of Legionnaires’ disease has increased in the past two decades. The natural habitat of Legionella is freshwater biotopes, where they mainly…
Chemists usually synthesize molecules using stochastic bond-forming collisions of the reactant molecules in solution. Nature follows a different strategy in…
Neuronal networks in the brain can process information particularly well when they are close to a critical point – or so brain researchers had assumed based on…
Our eyes — the windows to the soul — need constant care, and as we age, they sometimes also need significant repair.
Anyone who believes that plants are organisms “without brains” that lack the ability to perceive and respond to the environment is wrong. Plants exhibit…
Cells assemble dynamically: their components are continuously exchanging and being replaced. This enables the structures to adapt easily to different…
Two proteins that act as a 'clutch' in cells to put them in gear and drive our immune response have been identified for the first time.
First impressions are important – they can set the stage for the entire course of a relationship. The same is true for the impressions the cells of our immune…
What, if robots could smell? Sniffing explosives at the airport, diagnosing diseases based on a patient’s breath, locating gas leaks and much more?
Patients treated for acute myeloid leukemia (AML) often achieve remission but then later experience relapses due to surviving subpopulations of leukemia stem…
A stealthy new drug-delivery system disguises chemotherapeutics as fat in order to outsmart, penetrate and destroy tumors.
Biologists Laura Carolina Leal and Felipe Passos performed a series of experiments in Brazil's Northeast region – specifically in the interior of Bahia State,…
Viruses are justly feared as ingenious pathogens, causing diseases in everything they invade, including virtually all bacteria, fungi, plants and animals.
The statistical model used for the predictions combines long-term satellite tracking data of the whales' movement patterns with environmental data such as…
Until August, the researchers want to compare a common pollen trap with a mobile lidar (light radar) in order to find out whether it is possible to distinguish…
Scientists have confirmed that viruses can kill marine algae called diatoms and that diatom die-offs near the ocean surface may provide nutrients and organic…
