The "Goldilocks" zone: A key to cellular adaptability and resilience

In a discovery that could redefine how we understand cellular resilience and adaptability, scientists at Scripps Research have unlocked the secret interactions between a primordial inorganic polymer of phosphate known as polyphosphate (polyP), and two basic building blocks of life: DNA and the element magnesium.

Atom probe tomography reveals fluoride patterns in aging teeth

Teeth are essential for helping people break down the food they eat and are protected by enamel, which helps them withstand the large amount of stress they experience as people chew away. Unlike other materials in the body, enamel has no way to repair damage, which means that as we age, it risks becoming weaker with time.

Penn-led consortium to advance imaging of brain diseases

A Penn Medicine-led consortium of radiology and chemistry researchers across the United States will advance imaging of diseases like Parkinson's by testing radiotracers they identified that illuminate α-synuclein (αSyn) or 4R tau proteins on positron emission tomography (PET) scans.

Metabolic imaging detects ovarian cancer subtypes and predicts chemotherapy response

Study demonstrates how metabolic imaging differentiates high and low oxidative phosphorylation (OXPHOS) subtypes of high-grade serous ovarian cancer (HGSOC). By assessing metabolic activity, it also identifies early and variable responses to chemotherapy, improving precision in treatment strategies.

AI tool detects heart disease in CT scans originally meant for other purposes

With the help of an artificial intelligence (AI) tool, computed tomography (CT) scans taken to look for tumors or bleeding or infections, also revealed calcium buildup in arteries, a sign of worsening cardiovascular disease.

Visceral fat found to contribute to Alzheimer's disease development

Researchers have linked a specific type of body fat to the abnormal proteins in the brain that are hallmarks of Alzheimer's disease up to 20 years before the earliest symptoms of dementia appear, according to a study being presented today at the annual meeting of the Radiological Society of North America (RSNA).

Lung cancer screening with CT can identify coronary artery calcium

Lung cancer screening with low-dose chest computed tomography (CT) may detect more than just lung cancer. As new research in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.231602 shows, these CTs can identify coronary artery calcium, a strong risk factor for coronary artery disease (CAD), in patients without cardiac symptoms.

Malaria crystal structure offers clues for more effective medications

Prof. Leslie Leiserowitz first became intrigued by malaria when he was a young boy in South Africa. His father, who scouted the continent in search of wood for the family business, brought back not only tales of elephants and gorillas but also skin rashes and ringing in his ears, side effects of the quinine he took to prevent malaria.

Proactively screening diabetes patients for heart disease does not improve long-term survival

While coronary heart disease and diabetes are often seen in the same patients, a diagnosis of diabetes does not necessarily mean that patients also have coronary heart disease, according to a new study from researchers at Intermountain Health in Salt Lake City.
