Things Worth Noting
Geoengineering, or climate engineering, involves proposed methods like solar radiation management (SRM) and stratospheric aerosol injection (SAI) to cool Earth by reflecting sunlight, similar to volcanic effects. While research explores these ideas to fight global warming, some claim secret programs are already spraying particles from planes, creating persistent “chemtrails” instead of normal contrails. Allegations include […]
The classic riddle “which came first, the chicken or the egg?” is a philosophical paradox about origins and causality, but science clearly answers: the egg came first. Eggs as reproductive structures existed billions of years ago in single-celled organisms and evolved into amniotic eggs around 340 million years ago, allowing land-based development in reptiles and […]
Japan lifted its ban on human-animal embryo research in 2019, allowing scientist Hiromitsu Nakauchi to lead efforts in growing human organs inside animals like pigs using induced pluripotent stem cells (iPS cells). The technique, called blastocyst complementation, injects human cells into genetically modified animal embryos to create human-animal chimeras that develop targeted organs, such as […]
Turritopsis dohrnii, the immortal jellyfish, can reverse its life cycle from adult medusa back to a juvenile polyp, essentially achieving biological immortality. Found in temperate and tropical waters, this jellyfish can reset its development in response to stress, such as starvation or injury, through a process called transdifferentiation. Its ability to avoid aging and regenerate […]
The Coriolis effect, caused by Earth’s rotation, does not influence water drainage direction in sinks or toilets. While the myth suggests that water spins clockwise in the Southern Hemisphere and counterclockwise in the Northern Hemisphere, this is not true. The Coriolis force is too weak to affect small-scale water flow, with factors like basin shape, […]
A groundbreaking study from Hebrew University of Jerusalem challenges long-held assumptions in magneto-optics by revealing that light’s magnetic field plays a much larger role than previously thought. Traditionally, the Faraday effect, which causes polarization rotation of light in a magnetic field, was attributed mostly to the electric field of light. However, the new research shows […]
Bivalve molluscs like clams, mussels, and oysters are being used as living biosensors to monitor water quality. These filter feeders are highly sensitive to pollutants and close their shells when exposed to toxins, triggering alarms that can shut off water flow to prevent contamination. Equipped with sensors, bivalves provide real-time alerts, offering a low-cost, efficient […]
MIT’s 2025 study shows that relying on AI like ChatGPT for essay writing can reduce brain engagement and create “cognitive debt.” Using EEG, researchers found that AI users showed weaker neural connectivity, lower focus, and poorer memory of their own work. They also felt less ownership and produced more uniform, surface-level writing. Brain-only users showed […]
Susumu Ohno, a pioneering geneticist, bridged biology and music by exploring the patterns of repetition in DNA sequences, which mirror musical compositions. In his 1986 paper, he introduced the concept of DNA sonification, converting genetic codes into sound, revealing structural similarities between genetics and music. Modern interpretations of this idea extend to sound healing, with […]
Scientists are making real progress toward a unified theory of quantum gravity, aiming to link quantum mechanics with general relativity at the tiny Planck scale. Key approaches like string theory, loop quantum gravity, emergent gravity, and holography offer new ways to explain space-time, black holes, and the early universe. In 2025, breakthroughs from Aalto University […]
