Detecting melanoma before it becomes visible is a major challenge in dermatology. Now, scientists at the Université du Québec’s National Institute of Sciences (INRS), in collaboration with researchers at the Université de Montréal, have developed a promising solution. The system, called SMEAR-ULM, is a high-tech system that can detect skin cancer in its early stages by measuring small temperature changes on the skin’s surface. The research team, led by INRS professor Jinyang Liang, has published their findings in the journal Nature Sensors.. The study was carried out in close collaboration with multiple research teams, including those led by Professor Fiorenzo…

The vagus nerve connects the brain to major organs throughout the body and plays an important role in many bodily functions. For people with movement disorders attending physical therapy, stimulation of the vagus nerve through a non-invasive technique, transcutaneous auricular vagus nerve stimulation (taVNS), has emerged as an additional therapeutic intervention. However, researchers have not assessed how taVNS interacts with the motor system during exercise, and thus whether it could be useful in therapeutic strategies for people with exercise performance problems. new from JNeurosciDane Donegan and Parius Vizkaitis from the Federal Institute of Technology Zurich led a study to advance…

Eating a regular, consistent diet is associated with a lower chance of experiencing symptoms of depression. A recent analysis found that people who frequently skip staple meals were more likely to report depressed mood, but eating a variety of foods could moderate this association. The study was published in the Journal of Affective Disorders. Depression remains a leading cause of disability worldwide, affecting approximately 280 million people. Mental health professionals often focus on life events, genetics, and brain chemistry when trying to treat mood disorders. Recently, behavioral researchers have started paying more attention to lifestyle routines such as nutrition and…

Flinders University researchers have revealed new details about one of the ancient fish species closely related to the first animals that eventually migrated from water to land more than 380 million years ago. Using advanced neutron imaging techniques, scientists examined the skull and brain box. Kohalalepis jarubikia large predatory fish that lived during the Devonian period, often called the “Age of Fish.” This fossil was discovered in the Lashley Mountains region of Antarctica and is the only known fossil of its kind. High-tech image processing reveals ancient anatomy The researchers used non-destructive scanning methods to peer inside the fossil and…

Young women who engaged in non-suicidal self-harm had significantly different brain activity compared to healthy women when receiving positive and negative feedback on social media, and the severity of the brain differences reflected the severity of their symptoms. The new study was published in the journal Translational Psychiatry. Self-harm without suicidal intent (known as non-suicidal self-injury (NSSI)) is alarmingly common among young people, affecting an estimated one in five adolescents worldwide, and is particularly prevalent among women. This refers to intentionally harming oneself, such as cutting or burning, without intending to end one’s life. Exposure to social media is associated…

Amber from Myanmar’s Kachin region continues to reveal surprising glimpses of life from the age of dinosaurs. Preserved in 100 million-year-old resin are the fossils of an ancient forest ecosystem that once supported an incredible diversity of life, including species never seen before. Now, researchers at Munich’s Ludwig-Maximilians-University (LMU) have identified a newly discovered true bug (of the order Heteroptera) with one particularly unusual feature. Its front legs ended in large claw-like structures similar to crab claws. These appendages, known as serrations, function like forceps and are extremely rare among insects. Ancient insect with unusual crab-like claws “Previously, such sawtooths…

Researchers at the National Institutes of Health (NIH) have uncovered new details about how GLP-1 weight loss drugs such as semaglutide affect brain cells, revealing internal signaling processes that scientists are only beginning to understand. The findings, based on experiments in mice, shed light on why these drugs work differently for different people and why their effects often slow over time. GLP-1 receptor agonists, such as Ozempic and Wegovy, are already known to suppress appetite and promote weight loss. Scientists have also identified brain regions involved in those effects. However, until now, little was known about what happens inside the…

People who are prone to conspiratorial thinking don’t necessarily write fully formed conspiracy theories when asked to interpret ambiguous events, but their worldview still leaks into their writing through certain word choices. Recent research published in journals Pro Swan provides evidence that although these people may not spontaneously construct complex conspiracy plans, they consistently use a recognizable vocabulary of suspicion and power. Conspiracy theories are alternative narratives that explain major events as the secret work of a powerful and malicious group. Believing in these stories tends to have negative social consequences, including decreased trust in science and decreased compliance with…

Background and purpose Nonalcoholic fatty liver disease (NAFLD) is a common metabolic disease with a complex pathogenesis. Although epitranscriptomic modifications such as N6-methyladenosine (m6A) are thought to be involved in NAFLD, the role of N1-methyladenosine (m1A) and its regulators is poorly understood. Recently, YTHDF1, a well-characterized m6A reader, was also shown to recognize m1A. However, the functional consequences of this bispecificity are unknown. This study aimed to investigate the role of YTHDF1 in the development of NAFLD and investigate whether its function is mediated through recognition of RNA methylation modifications on specific target mRNAs. method The expression of YTHDF1 in…

GOLDENDALE, Wash. – Members of the Yakama Nation gathered on high ground on the Washington side of the Columbia River near the John Day Hydroelectric Dam to protest a proposed clean energy storage project on the tribe’s sacred land. Supporters of the Goldendale pumped storage energy storage project say it will help meet the region’s growing energy needs, with project developers touting its potential to one day power up to 500,000 homes without emitting harmful greenhouse gases into the atmosphere. But there is growing evidence that large data center campuses may be one of the main beneficiaries of that power.…
