The long-running scientific debate may finally be coming to an end. A new study involving Ashley Poust of the University of Nebraska State Museum provides strong evidence that: nano tyrantIt is often described as a smaller version of . tyrannosaurus rexwhich was actually a real different species. A research team led by Princeton University’s Christopher Griffin focused on the original fossil Nanotyrannus skull, housed at the Cleveland Museum of Natural History. To determine the animal’s age at death, the researchers examined a little-studied bone known as the ceratobranchial or hyoid bone that had been preserved with the skull. The researchers…
Waters Corporation today announced the launch of the Waters omniDAWN™ multi-angle light scattering (MALS) photometer, part of the Wyatt Technology portfolio. With 18 detection angles, the omniDAWN photometer is the first extended range MALS detector for ultra-high performance liquid chromatography (UHPLC) and ultra-performance liquid chromatography (UPLC) workflows, delivering absolute molar mass and size measurements without compromising resolution or throughput. Image credit: Waters Corporation The omniDAWN MALS photometer extends UPLC-compatible sizing by a factor of 10, enabling reliable characterization of more complex analytes including large molecules and advanced materials.

The genetic adaptations that allow animals such as yaks and Tibetan antelopes to survive in the absence of air may also point to new ways to repair nerve damage in humans. Researchers report that this mutation may help restore damaged nerve insulation in conditions such as cerebral palsy and multiple sclerosis (MS). This study was published in the Cell Press journal neuronwe have identified natural biological pathways that support neural regeneration and may be harnessed using molecules already present in the human body. “Evolution is a great gift from nature, providing a variety of genes that help organisms adapt to…
Casey Moravec, an attorney with the Southern Environmental Law Center, spoke at a public hearing Tuesday in Fayetteville on proposed monitoring and minimization rules for industrial emitters of 1,4-dioxane and public wastewater treatment plants that receive their wastewater. Photo: Trista Talton FAYETTEVILLE — Proposed monitoring and minimization rules for industrial emitters of 1,4-dioxane and public wastewater treatment plants that accept the waste from those facilities fail to protect North Carolinians’ drinking water, speakers at a public hearing said Tuesday. All but one of the 13 people who spoke at the North Carolina Environmental Control Commission’s public hearing at Fayetteville Technical…
A new MRI study suggests that a diet high in ultra-processed foods may be associated with thicker, poorer thigh muscles in adults at risk of knee osteoarthritis, adding new concerns about how modern dietary patterns affect mobility and aging. Study: Ultra-processed foods and muscle fat infiltration in thigh MRI: data from the Osteoarthritis Initiative. Image credit: Atiketta Sangasaeng / Shutterstock Recent research published in journals Radiology Consumption of ultra-processed foods (UPF) is associated with increased fat infiltration in the thigh muscles on magnetic resonance imaging (MRI), a marker of decreased muscle quality in people at risk for knee osteoarthritis. Analysis…
A new review claims that while processed meat provides high-quality protein and key micronutrients, the health risks may not be as clear-cut as many guidelines suggest. Review: Processed meat in the diet: general nutritional profile – protein quality and micronutrients. Image credit: The Image Party / Shutterstock In a recent article published in a magazine animal frontierthe authors published a perspective review of the nutritional content, protein quality, and claimed health effects of processed meat in the human diet. background Processed meat has become a major component of the human diet due to its shelf life, convenience, and nutritional value.…
A recent experiment investigated whether simple visual cues of mating movements cause sexual arousal in heterosexual men and women. The results showed that watching muted clips of various mating animal species did not increase blood flow to the genitals or induce self-reported arousal in either sex. These observations were published in the journal Archives of Sexual Behavior. Lucy Krejčová, a researcher at Charles University in Prague, and her colleagues developed the experiment to test existing theories about human sexual response. They wanted to understand the specific visual triggers that cause the human body to physically prepare for intercourse. Physical arousal…
A new paper argues that foods alone do not confer certain health benefits. What matters is what you replace on your plate, and that change can change how you interpret nutritional evidence. Opinion: Is this food healthy? Reconstructing nutritional evidence through counterfactual comparisons. Image credit: Anna Puzatykh / Shutterstock Recent opinion papers published in magazines clinical nutrition We advocate reframing nutrition research through counterfactual comparisons. Nutritional science, despite decades of research, continues to produce conclusions that are often perceived as context-dependent or inconsistent. Nutritional science often relies on surrogate results, such as intermediate physiological measurements and biomarkers, whose interpretation depends…
A major European trial suggests that reducing milk protein in infant formula may not lower BMI by age two, but may help put early growth on a more stable trajectory. Trial: Infant Milk Intervention Trial (ToMI): A randomized controlled trial of the effect of protein content in infant milk on BMI and growth. Image credit: MIA Studio / Shutterstock In a recent study published in the journal clinical nutritionresearchers present results from the Infant Milk Intervention (ToMI) trial, a multicenter (Spanish and German) randomized controlled trial (RCT) that investigated whether reducing protein intake during the first two years of life…
Northwestern University psychologist Andrea Russell sees anxiety in older adults with early cognitive impairment. Some people worry that missing words or forgetting appointments can be a sign of Alzheimer’s disease. Some people are afraid of making mistakes in public. Some people are too scared to consult a doctor. Seeing that uncertainty and the stigma surrounding dementia, Russell spearheaded a new study at Northwestern Medicine that found the majority of older adults are willing to undergo blood tests for biomarkers to assess their risk of Alzheimer’s disease. The study will be published April 15 in Alzheimer’s & Dementia: The Journal of…
