Foraminifera are single-celled organisms, the majority of which live on or within the seafloor sediment. They are responsible of the beautiful red pigment that characterizes Komodo Island's Red Beach, Indonesia. [📹 Oni Hoironi / onihoironi]

Dolphin stampedes are also sometimes referred to as “super pods” or “megapods”. They can gather up to thousands of dolphins. This one was filmed off the coast of San Diego. [📹 taylor.parent]

Handwriting matters!!!
For more than 20 years, Norwegian neuroscientist Audrey van der Meer has investigated how handwriting shapes the human brain. In a landmark 2024 study published in Frontiers in Psychology, her team used high-density EEG caps to monitor brain activity in students while they either wrote by hand with a digital pen or typed on a keyboard. The difference was dramatic. Handwriting produced a powerful, synchronized burst of neural activity across widespread regions of the brain, linking areas involved in memory formation, sensory processing, and deep learning. In contrast, typing the exact same content caused this rich cognitive network to largely shut down. Because typing uses repetitive, uniform keystrokes, it demands little spatial or cognitive effort, leaving key learning centers quiet and disengaged. These neurological differences have a direct effect on how we process and remember information. Earlier research by Pam Mueller and Daniel Oppenheimer at Princeton University reached similar conclusions. Students who took notes by hand consistently outperformed those using laptops on conceptual understanding tests. Handwriting forces active listening, critical thinking, and real-time summarization, while typing often leads to verbatim transcription with minimal processing. Our brains function as part of an embodied biological system. Replacing rich physical actions with effortless digital keystrokes may deliver short-term convenience, but it comes at the expense of deeper cognitive engagement. The solution is simple and timeless: pick up a pen. [Van der Meer, A. L. H., et al. (2024). Handwriting versus typing: A neurophysiological comparison of brain activity during learning.
