Scientists at Sanford Burnham Prebys Medical Discovery Institute and the Centro de Biología Molecular Severo Ochoa in Spain have created a test that determines which children with CAD deficiency—a rare metabolic disease—are likely to benefit from receiving uridine, a nutritional supplement that has dramatically improved the lives of other children with the condition. The study was published in Genetics in Medicine.

Researchers at Washington University in St. Louis and the National Institutes of Health (NIH) have found that genes that confer the power to destroy tetracycline antibiotics are widespread in bacteria. But the researchers have also created a chemical compound that shields tetracyclines from destruction, restoring the antibiotics lethality. The findings indicate an emerging threat to one of the most widely used classes of antibiotics — but also a promising way to protect against that threat.

Researchers at Henry Ford Health System in Detroit say early diagnosis of a life-threatening blood clot in the lungs led to swifter treatment intervention in COVID-19 patients. In a new study published recently in the journal Radiology, researchers found that 51 percent of patients found to have a pulmonary embolism, or PE, were diagnosed in the Emergency Department, the entry point for patients being admitted to the hospital.

The collection of more than 25,000 fragments of ancient manuscripts known as the Dead Sea Scrolls include, among other ancient texts, the oldest copies of books of the Hebrew Bible. But finding a way to piece them all together in order to understand their meaning has remained an incredibly difficult puzzle, especially given that most pieces weren't excavated in an orderly fashion.

Weizmann Institute scientists show that bacteria live inside all cancer cells, from brain to breast to bone, and that each type of cancer has its own type of bacteria. Understanding this relationship could help predict treatment effectiveness or lead to ways of using the bacteria to boost treatments.

Researchers at Tulane University School of Medicine identified a gene that causes an aggressive form of breast cancer to rapidly grow. More importantly, they have also discovered a way to “turn it off” and inhibit cancer from occurring. The animal study results have been so compelling that the team is now working on FDA approval to begin clinical trials and has published details in the journal Scientific Reports.

Microcapsules for the storage and delivery of substances are tiny versions of the type of capsule used for fish oil or other liquid supplements. A new method for synthesizing microcapsules, reported in AIP Advances, creates microcapsules with a liquid core that are ideal for the storage and delivery of oil-based materials in skin care products. They also show promise in some applications as tiny bioreactors. In this new method, a surfactant-free microfluidics process is used.

Throughout an individual’s lifetime, the uterus undergoes spontaneous contractions of the uterine wall, which can induce uterine peristalsis, a specific wavelike contraction pattern. These contractions are important for many reproductive processes, but hyperperistalsis could impede fertility and lead to diseases, such as adenomyosis or endometriosis. In an APL Bioengineering article, researchers present two mechanobiology tools for experiments on synthetic or artificial uterine tissue. They wanted to study the negative effects of hyperperistalsis.

More than 1,000 bottlenose dolphins live in Florida’s Indian River Lagoon year-round. Although extensively studied, what they do at nighttime is still a mystery. Using satellite telemetry, scientists provide the first documentation that these dolphins have a larger range that encompasses more habitats than previously thought. They regularly leave the brackish waters of the estuarine system and, not only travel into the ocean, but swim substantial distances – up to 20 kilometers – up freshwater rivers, creeks, and canals.

Graphene triangles with an edge length of only a few atoms behave like peculiar quantum magnets. When two of these nano-triangles are joined, a "quantum entanglement" of their magnetic moments takes place: the structure becomes antiferromagnetic. This could be a breakthrough for future magnetic materials, and another step towards spintronics. An international group led by Empa researchers recently published the results in the journal "Angewandte Chemie".

Approximately three quarters of the deaths associated with COVID-19 in the nation’s capital have been among the African American community. A new Georgetown University report illuminates entrenched health and socioeconomic disparities that explain one reason this is occurring. Main points: • 15-year difference in the life expectancy between residents in Ward 3 and Ward 8; • Residents from Wards with more Black residents (5, 7, and 8) more likely hospitalized for preventable health conditions; • Number of Blacks who are obese is 3x higher than Whites; • Number of Blacks with diabetes is 7x higher than Whites; • Number of Blacks who die from heart disease is 2.5 times higher than Whites; • Median household income is 3x less for Blacks; and • Blacks have the lowest percentage of bachelor degree attainment.
