OAK BROOK, Ill. – Knowing a patient’s symptoms helps radiologists in lumbar spine MRI interpretation and diagnosis, according to a study published today in Radiology, a journal of the Radiological Society of North America (RSNA). MRI is the most important imaging exam in patients with back pain or sciatica because it shows nearly all degenerative and structural abnormalities of the spine. However, MRI often shows spinal abnormalities in individuals who do not have symptoms. Because the same abnormalities can ...

Prostate cancer is the second most common cancer in men, and almost 300,000 individuals are diagnosed with it each year in the U.S. To develop a consistent method of estimating prostate cancer size, which can help clinicians more accurately make informed treatment decisions, Mass General Brigham researchers trained and validated an AI model based on MRI scans from more than 700 prostate cancer patients. The model was able to identify and demarcate the edges of 85% of the most radiologically aggressive prostate lesions. Tumors with a larger volume, as estimated by the AI model, ...

An international coalition of researchers from the United States and Italy has discovered a novel strain of cyanobacteria, or algae, isolated from volcanic ocean vents that is especially adept at growing rapidly in the presence of CO2  and readily sinks in water, making it a prime candidate for biologically-based carbon sequestration projects and bioproduction of valuable commodities. This strain, nicknamed “Chonkus,” was found off the coast of the island of Vulcano in Sicily, Italy — an environment in which marine CO2 is abundant due to shallow volcanic vents. The discovery is described in a paper published ...

Today, people increasingly seek non-alcoholic versions of beer or wine. Despite boasting different flavors, these two drinks share many aromas, which makes it difficult to produce alcohol-free versions that mimic the real thing. Researchers in ACS’ Journal of Agricultural and Food Chemistry report on a literature analysis and experiment to characterize the chemical compounds that give beer and wine their unique fragrances. They say their findings could aid the development of flavorful, non-alcoholic substitutes. Food and beverage researchers are working to recreate the enjoyable aromas and flavors of beer and wine in alcohol-free substitutes. However, because both beer and ...

Complaining about your allergies online might provide valuable data to researchers. Over 25% of Americans experience seasonal allergies, but how the prevalence of seasonal allergies varies across space and time remains obscure, in part because allergies seldom warrant visits to healthcare providers. Elias Stallard-Olivera and Noah Fierer mined Twitter (now X) posts and Google searches from 2016–2020 to extrapolate spatial and temporal allergy patterns. A natural language processing model sorted posts that indicated symptoms (e.g., “My allergies are really bad today!!”) from posts that include key words but did not indicate the presence of symptoms (e.g., “Gluten ...

A pitiful sound from tinny speakers, sad virtual eyes, trembling robot arms: it doesn’t take much to feel sorry for a robot. This is the conclusion of a study by Marieke Wieringa, who will be defending her PhD thesis at Radboud University on 5 November. But she warns that our human compassion could also be exploited: just wait until companies find a revenue model for emotional manipulation by robots. Objectively, we know that a robot cannot experience pain. Still, under certain circumstances, ...

There is power in numbers, or so the saying goes. But in the ocean, scientists are finding that fish that group together don’t necessarily survive together. In some cases, the more fish there are, the larger a target they make for predators.  This is what MIT and Norwegian oceanographers observed recently when they explored a wide swath of ocean off the coast of Norway during the height of spawning season for capelin — a small Arctic fish about the size of an anchovy. Billions of capelin migrate each February from the edge of the Arctic ...

A living cell is a bustling metropolis, with countless molecules and proteins navigating crowded spaces in every direction. Cell division is a grand event which completely transforms the landscape. The cell starts behaving like the host of an international competition, reconfiguring entire streets, relocating buildings and rerouting its transportation systems.  For decades, researchers have been captivated by the cell's ability to organise such a dramatic transformation. Central to the process is the microtubule cytoskeleton, a network of fibres which provides structural support and facilitates movement within the cell, ensuring that chromosomes ...

Our ability to see starts with the light-sensitive photoreceptor cells in our eyes. A specific region of the retina, termed fovea, is responsible for sharp vision. Here, the color-sensitive cone photoreceptors allow us to detect even the smallest details. The density of these cells varies from person to person. Additionally, when we fixate on an object, our eyes make subtle, continuous movements, which also differ between individuals. Researchers from the University Hospital Bonn (UKB) and the University of Bonn have now investigated how sharp vision is linked to these tiny eye movements and ...
