An adult brain affected by attention deficit disorder with or without hyperactivity (ADHD) presents modifications similar to those observed in individuals suffering from dementia. These are the findings of a study which shows that, compared with healthy individuals, patients with an ADHD diagnosis have more iron in certain regions of their brain along with higher levels of neurofilaments[1] (NfL) in their blood. These markers have been consistently reported to be... Read more ›

Life needs sufficient phosphorus. However, the element is scarce, not only today but also at the time of the origin of life. So where was there sufficient phosphorus four billion years ago for life to emerge? A team of origin-of-life researchers has an answer. Read more ›

Obesity prevention strategies often focus on diet, but eating behaviors also play a key role. In a recent study, researchers from Japan investigated factors influencing meal duration, including sex differences, chewing patterns, and rhythmic cues. Their findings suggest that eating more slowly -- by increasing chews per bite or using slow rhythmic cues -- may help reduce food intake. These insights could inform practical, low-cost obesity prevention strategies by promoting... Read more ›

Enzymes originally evolved in high-temperature environments and later adapted to lower temperatures as Earth cooled. Scientists discovered that a key shift in enzyme function occurred over evolutionary time due to amino acid changes distant from the active site. These mutations lowered activation energy, enhancing catalytic efficiency at low temperatures. Their findings highlight how global cooling events influenced enzyme evolution. Read more ›

Researchers have developed a highly accurate land cover map for Siberia, providing insights into climate change and predictions. Using advanced machine learning techniques and existing multiple land cover maps, they were able to address the significant discrepancies found in the previous datasets. Being one of the world's most climate-sensitive regions, Siberia's newly developed map marks a breakthrough, providing critical details crucial for understanding the region's extreme environmental changes.

Delayed and disorderly energy transitions will threaten economic and financial stability whilst also increasing the economic risks from climate change, according to a new study. Conversely, transitions that are started sooner are likely to be more orderly and economically beneficial. Read more ›

What goes through your mind when someone asks 'Did you see that?' A study shows that children and adults process ambiguous information like 'that' differently. While children focus more on the literal meaning, adults use multiple cues to grasp the speaker's intent. Researchers hope their findings could aid dialogue robot development and improve support systems for individuals with communication difficulties. Read more ›

Researchers have determined that six gas valves provide the best protection against plasma disruptions in SPARC, a next-generation, experimental fusion system. By refining the setup for the fusion vessel's massive gas injection system, researchers are ensuring that disruptions -- sudden jets of plasma that can damage the fusion vessel's inner walls -- are controlled efficiently, paving the way for safer, more robust fusion power plants.

Researchers wondered if there was a more ethical way to enjoy foie gras, so they created a process to replicate the dish without force-feeding ducks and geese beyond their normal diets. They treated the fat with the bird's own lipases, mimicking the activities that occur naturally in the duck's body, and the resultant foie gras looked correct with noninvasive laser microscopy. The team confirmed the physical properties with stress-deformation tests... Read more ›

Researchers have found a potential new way to slow the progression of lung fibrosis and other fibrotic diseases by inhibiting the expression or function of Piezo2, a receptor that senses mechanical forces in tissues including stress, strain, and stiffness. The new study sheds light on the underlying mechanisms of pulmonary fibrotic diseases and identifies potential new targets and options for therapy to improve patients' outcomes. Read more ›

Researchers examine the properties of several dairy-free butter alternatives inside one of the region's most well-known snacks: Scottish shortbread. The group tested the alternatives in their lab, selecting three types of vegan butter substitutes with different levels of fat and comparing their consistencies and responses to heat. The vegan alternative with the highest fat content behaved like butter when baked and yielded the most positive feedback in taste testing. Butter... Read more ›

The pathogen C. diff -- the most common cause of health care-associated infectious diarrhea -- can use a compound that kills the human gut's resident microbes to survive and grow, giving it a competitive advantage in the infected gut. A team has discovered how C. diff (Clostridioides difficile) converts the poisonous compound 4-thiouracil, which could come from foods like broccoli, into a usable nutrient. Their findings increase understanding of the... Read more ›
