The antibody, already in clinical trials to treat COVID-19, may be effective against future variants.
Scientists to develop a novel diabetes treatment involving transplanting pancreas cells that produce insulin.
Laser powder bed fusion, a 3D-printing technique, offers potential in the manufacturing industry, particularly when fabricating nickel-titanium shape memory alloys with complex geometries. Although this manufacturing technique is attractive for applications in the biomedical and aerospace fields, it has rarely showcased the superelasticity required for specific applications using nickel-titanium...
Redness, swelling, pain -- these are signs of inflammation. It serves to protect the body from pathogens or foreign substances. Researchers were able to show that inflammatory reactions of an important sensor protein proceed in a specific spatial direction. This finding has the potential to conceivably stop inflammation at the 'growing end', and thus bring chronic inflammatory diseases to a halt.
Hopeful diabetes treatment, islet cell transplantation, is now one step closer to the clinic following new study.
A novel technique to measure the age of male sperm has the potential to predict the success and time it takes to become pregnant, according to a newly published study.
Systems in which mechanical motion is controlled at the level of individual quanta are emerging as a promising quantum-?technology platform. New experimental work now establishes how quantum properties of such systems can be measured without destroying the quantum state -- a key ingredient for tapping the full potential of mechanical quantum systems.
Researchers managed to set larger groups of malaria parasites into motion and to analyze the acquired image data. The collectively moving pathogens form vortex systems that are largely determined by physical principles. Computer simulations helped identify the mechanisms underlying these rotating movements.
Researchers are investigating better ways to predict where road-clogging debris will be most severe after tropical cyclones.
The microbes that help break down food actually tell the gut how to do its job better, according to a new study in mice. The researchers said it appears that the microbes are able to influence which of the gut's genes are being called into action, and in turn, that interaction might lead to a remodeling of the epithelial cells lining the gut so that they match the diet.
How do our cells organize themselves to give their final shape to our organs? The answer lies in morphogenesis, the set of mechanisms that regulate their distribution in space during embryonic development. A team has just made a surprising discovery in this field: when a tissue curves, the volume of the cells that compose it increases instead of decreasing. This discovery opens new avenues for in...
Researchers have identified how the brain triages emotions during dream sleep to consolidate the storage of positive emotions while dampening the consolidation of negative ones. The work expands the importance of sleep in mental health and opens new ways of therapeutic strategies.
In early research, the oral medication zanubrutinib was found to help most patients with a slow-growing type of cancer known as marginal zone lymphoma.
The transgenic papaya 'SunUp' was developed in the 1990s and was widely publicized because of its ability to resist the papaya ringspot virus. A new study has now identified the genomic changes involved and how they influence the transgenic plants.
Researchers have untangled the intricate physics and neural controls that enable dragonflies to right themselves while they're falling.
Patients prescribed antibiotics in hospital are more likely to get fungal infections because of disruption to the immune system in the gut, according to a new study.
The effect of variability on learning is recognized in many fields: learning is harder when input is variable, but variability leads to better generalization of the knowledge we learned. In this review, researchers bring together over 150 studies on variability across domains, including language acquisition, motor learning, visual perception, face recognition and education, shedding light on the...
Life-like organ replicas -- so-called 3D organoids -- are a good way to research disease processes. A team has now presented a kind of blueprint for such a model of the cervix.
A single hormone appears to coordinate the lifespan extension produced by a low-protein diet. Low-protein diets produce beneficial metabolic effects in aged mice, improving metabolic health, reducing frailty, and extending lifespan. These beneficial effects were also apparent when protein intake was reduced in middle-aged mice, even protecting against the detriments of obesity. Importantly, these...
For our sake and the environment, there is a considerable amount of research into the reduction of plastic for many and various applications. Researchers have now found a way to imbue relatively sustainable paper materials with some of the useful properties of plastic. This can be done easily, cost effectively, and efficiently. A coating called Choetsu not only waterproofs paper, but also...
A research team has investigated a meteorite from Mars using neutron and X-ray tomography. The technology, which will probably be used when NASA examines samples from the Red Planet in 2030, showed that the meteorite had limited exposure to water, thus making life at that specific time and place unlikely.
Human cell division involves hundreds of proteins at its core. Knowing the 3D structure of these proteins is pivotal to understand how our genetic material is duplicated and passed through generations. Scientists are now able to reveal the first detailed structure of a key protein complex for human cell division known as CCAN. By using cryo-electron microscopy, the researchers show important...
Organisms adjust their cell walls according to environmental conditions such as temperature. Some adaptations involve changes in lipids which may still be preserved long after the rest of the organisms has been degraded. Researchers have studied a specific group of lipids called long chain diols which are found in sea sediments all over the world, and which can be preserved for millions of years.
Switching to low carbon fuels for transportation, cooking, heating, power generation and other needs would help fight climate change and also reduce racial and ethnic disparities in exposure to air pollution.
