    Capturing the Meaning of Moments: The Science of Selfies and Why People Include Themselves in Photos

    Lead Image: A recent study provides insights into people’s motivations for including themselves in photos. Published in the journal Social Psychological and Personality Science, the research discovered that first-person photos, offering the scene from the individual’s viewpoint, best represent the physical experience of an event. However, third-person images, such as selfies, more effectively convey the deeper significance of the event. The study, which included six experiments involving 2,113 participants, challenged the notion that people primarily post selfies on platforms like Instagram for self-promotion. It suggested that the perspective of the photo aligns with the individuals’ intent, whether to capture the…

    Appetite-Control Capsule: Ingestible Electroceutical Tames Hunger Hormones

    Lead Image: Researchers have developed an ingestible capsule called FLASH (Fluid-wicking Active Stimulation and Hormone modulation) that can electronically stimulate the hunger-regulating hormone ghrelin in pigs. Inspired by the fluid-wicking skin of the Australian thorny devil lizard, the capsule emits electronic signals and moves through the body, eventually being excreted. This proof-of-concept study demonstrates the potential of ingestible electroceuticals for treating gastrointestinal, neuropsychiatric, and metabolic disorders. The team plans to continue researching for human application and explore treatment options for eating disorders and metabolic diseases.

    Clearing the Air: How Do We Capture and Store CO2?

    Carbon dioxide (CO2) emissions, which account for 81% of all greenhouse gases, pose a significant challenge to Earth’s climate. As natural methods are unable to fully counteract the rising levels of human-produced emissions, scientists and policymakers are exploring carbon capture, utilization, and storage (CCUS) techniques to reduce atmospheric CO2. These methods include ocean alkalinity enhancement, direct air capture, carbon offsets, carbon farming, reforestation, and afforestation. Newer strategies, such as accelerated limestone weathering, geological sequestration, and solar fuels, are also being researched. The global push for carbon reduction is partly driven by the Paris Climate Agreement, which aims to limit the…

    Sea Urchin Killer Identified: Scientists Unmask the Microscopic Menace Behind Massive Die-Off Event

    A scuticociliate, a single-celled organism, has been identified as the cause of the 2022 mass die-off of long-spined sea urchins in the Caribbean and Florida’s east coast. These urchins are crucial for coral reef health, and the discovery raises questions about the ciliate’s presence, growth conditions, and potential impact on other species.  Photo of Long Spined Sea Urchin (Diadema antillarum). The mass die-off of the long-spined sea urchin – a loss that threatens the health of coral reefs from the Caribbean to Florida’s east coast – was caused by a one-celled organism called a ciliate. The search for the 2022…
