Drawing inspiration from natural marvels to make new materials
A tiny bristle worm, wriggling around the ocean, can extend its jaw outside its mouth to ensnare its prey. The worm’s shape-shifting jaw, stiff at the base and flexible at the end, is made of one singular material containing the mineral zinc and the amino acid histidine, which together govern the joint’s mechanical behavior through what is known as a metal coordination chemistry.
Scientists like LaShanda Korley, Distinguished Associate Professor of Materials Science and Engineeringand Chemical and Biomolecular Engineering at the University of Delaware, want to recreate these chemistries and build similar structures in synthetic materials. By doing so, they can develop new, improved materials for use in sensors, healthcare applications, and much more. Chemistries like these are ubiquitous in nature. The iron-protein interaction in human blood, for example, can be a determinant of disease.
C. diff might not originate from external transmission but rather from within the infected patient themselves. Hospital staff dedicate significant effort to safeguard patients from infections during their hospital stay. Through practices ranging from [...]
Google says it has made a significant step in identifying disease-causing genes, which could help spot rare genetic disorders. A new model named AlphaMissense is able to confidently classify 89 per cent of all [...]
MINDWATCH study reveals cognitive peaks with everyday pleasures. Listening to music and drinking coffee are the sorts of everyday pleasures that can impact a person’s brain activity in ways that improve cognitive performance, including [...]
Moderna has developed a new and improved version of its COVID-19 vaccine. The unique formulation (mRNA-1283) reduces the vaccine's content from the full-length SARS-CoV-2 spike protein to a narrowly focused encoding of just two [...]
Breast cancer in its various forms affects more than 250,000 Americans a year. One particularly aggressive and hard-to-treat type is triple-negative breast cancer (TNBC), which lacks specific receptors targeted by existing treatments. The rapid [...]
Scientists from Nanyang Technological University, Singapore (NTU Singapore) have created a process that can upcycle most plastics into chemical ingredients useful for energy storage, using light-emitting diodes (LEDs) and a commercially available catalyst, all [...]
The mere scent of seafood can severely sicken those allergic to it — and therefore they are more likely to avoid it. Similarly, individuals who experience food poisoning from a specific dish tend to [...]
Researchers in Germany and Japan have been able to increase the diffusion of magnetic whirls, so-called skyrmions, by a factor of ten. In today’s world, our lives are unimaginable without computers. Up until now, [...]
Omicron infections have a lower risk of long COVID than earlier variants, according to a study analyzing data from 11,000 participants. The risk of developing long COVID is significantly lower following an infection with [...]
Researchers have discovered that insulin resistance, typically linked with type 2 diabetes, is also present in cancer patients and can accelerate the spread of the disease. In the 1920s, scientists found that the urine [...]
Scientists from ETH Zurich and the University of Geneva have developed a new technique that allows them to observe chemical reactions taking place in liquids at extremely high temporal resolution. This innovation enables them to track how molecules [...]
Research published recently suggests that Pfizer’s erectile dysfunction drug Viagra can decrease the risk of developing Alzheimer’s disease by up to 69 percent. The research, which was published in Nature, found that the medication has [...]
An AI-powered model utilizes chest X-rays to help develop biomarkers for aging. What if determining “your age” was based on your chest rather than your face? Scientists from Osaka Metropolitan University have crafted an [...]
Cancer biomarkers circulating in body fluids can be used for diagnosis and treatment monitoring. However, current detection technology lacks the required sensitivity, limiting biomarker use in clinical applications. Colorectal cancer is the second most [...]
The findings could lead to a cure for LAM. Researchers from the University of Cincinnati may have identified a potential treatment for lymphangioleiomyomatosis (LAM), a rare lung condition resembling cancer found predominantly in women of reproductive [...]
