An exceptionally well-preserved fossilized molar belonging to an adult Pacific mastodon has surfaced in a nature preserve near San Francisco.Upon first glance, the ancient tooth looked like an “oddly shaped rock” to geologists who were conducting fieldwork in the area, according to a statement from the Midpeninsula Regional Open Space (Midpen), which runs the preserve. But the find was quickly unmasked as a valuable fossil from the last ice age and was sent to scientists at Stanford University for carbon dating.”The tooth itself is in immaculate condition,” Wayne Thompson, a paleontologist and the CEO of Pacific Paleontology, a consulting firm…

An international team of researchers, including Earth-Life Science Institute (ELSI) at the Institute of Science Tokyo, has developed a protein language model that brings together two fundamental sources of information about proteins: their amino acid sequences and their three-dimensional structures. The model provides researchers with a new way to map relationships across the protein universe and investigate how proteins have evolved over billions of years. The research was led by Prof. Rachel Kolodny and PhD candidate Guy Yanai of the University of Haifa, Prof. Nir Ben-Tal and graduate student Gabriel Axel of Tel Aviv University, and Specially Appointed Associate Professor…

Iron is an essential micronutrient, but excess iron can damage cells and increase cancer risk. While many cells die from iron-induced oxidative stress, a subset survives and may become cancerous. Previously, the identity of these surviving cells was unclear.A Japanese research team has demonstrated that giant-nucleus cells that survive iron-induced damage form the foundation of early-stage cancer. The team anticipates that these giant-nucleus cells could serve as early indicators of cancer, as they are easy to identify under a microscope. The study was published in the journal Redox Biology. Since the 1980s, scientists have spotted cells with abnormally large…

While artificial intelligence (AI) systems can now solve challenging math equations and respond in human-like language, the question of AI consciousness has moved from the realm of sci-fi to scientific discussion.The debate has become more mainstream thanks to a recent preprint study that examined “consciousness steering,” an AI-tuning technique that affects how an AI model expresses ideas about self-awareness. The researchers suggested that if AI is allowed to claim it is conscious, it’s also more likely to state that it believes in ghosts or vampires.Although the study hasn’t been peer-reviewed yet, it raises a big question in the world of…

Risk factors for cardiovascular-kidney-metabolic disease, a health condition made up of heart disease, kidney disease, diabetes, and obesity, can be identified in children as young as 8, UTHealth Houston researchers discovered.  Using a group of 273 children who participate in the Border Health Research Cohort within the Border Health Research Center at UTHealth Houston School of Public Health in Brownsville, researchers analyzed 5,000 proteins and identified six “signatures” of proteins that significantly influence the risk of developing cardiovascular-kidney-metabolic disease in adulthood. The same protein signature was present in 685 adults from the same community who were at high risk of…

Employer and consumer organizations are urging lawmakers to address “loopholes” in the No Surprises Act. In a letter (PDF) submitted to House and Senate leaders on both sides of the aisle, nearly 70 groups representing employers, patients and labor unions argue that while the law has successfully averted millions of surprise medical bills, flaws in its processes are driving up healthcare costs. They particularly point to the independent dispute resolution, or IDR, process, which has seen a growing contingent of critics. IDR is a baseball-style arbitration that is designed as a second level for resolving a claim if a payer…

Influenza remains a major global health challenge as continual antigenic drift can limit the breadth and durability of vaccine-induced antibody responses, requiring frequent vaccine updates. Researchers are therefore seeking strategies to generate broader, longer-lasting protection. A key focus is the germinal-center (GC), where B cells undergo selection and somatic hypermutation to produce diverse, high-affinity antibodies and long-lived memory B cells. Researchers from Korea University College of Medicine, Republic of Korea, led by Associate Professor Jiwon Lee in the Department of Convergence Medicine and the Vaccine Innovation Center, investigated whether an mRNA-based influenza vaccine could stimulate stronger and more persistent GC…

A multidisciplinary scientific team at the University of Malaga has developed a new technology based on magnetic nanoparticles that enables precise, rapid and reliable diagnosis of allergy to beta-lactam antibiotics, including amoxicillin and other penicillins. This is a “highly efficient” in vitro diagnostic platform based on 30 nm nanoparticles with an iron oxide core and silica shell, which act “like a tiny magnet covered with thousands of molecular hooks”. If the patient’s blood contains the IgE antibodies responsible for the allergy, they are captured much more readily than with conventional methods.” Ezequiel Pérez-Inestrosa, Professor of Organic Chemistry, University of Malaga…

Researchers at the University of Oslo have mapped which parts of our DNA carry the inherited differences behind complex traits and disorders. The more complex the trait, the more of those differences lie in the DNA between genes rather than in the genes themselves. This suggests that much of what shapes psychiatric and cognitive conditions lies in the parts of the genome that we understand the least. Schizophrenia, height, cholesterol. Each has its own genetic signature. That signature is made up of genetic variants: small differences in the DNA sequence that make one person’s genome differ from another’s. Some traits,…
