Millions of graphene-based toothbrushes have already reached consumers, long before scientists fully understood how the material actually works. Now, new research from the Korea Advanced Institute of Science and Technology (KAIST) has clarified the mechanism behind graphene oxide’s antibacterial properties. Led by Sang Ouk Kim and Hyun Jung Chung, the study shows that graphene oxide…
Jared Isaacman (Image/AP) Nasa Administrator Jared Isaacman has reiterated his support for restoring Pluto’s status as a planet.Speaking during a US Senate hearing on Tuesday, Isaacman voiced strong support for reconsidering Pluto’s classification.“Senator, I am very much in the camp of ‘make Pluto a planet again,’” Isaacman said while responding to a question from Senator…
Why NASA keeps watching this 30-mile-wide “eye” in the Sahara from space? Image credits – Wikimedia Looking down from space, astronauts on board the International Space Station spotted a fascinating landform in the Sahara Desert. This resembles a huge eye looking back up into space. The eye of the Sahara has been officially named the…
A huge pink heart-shaped structure has recently been sighted by NASA’s astronauts on the International Space Station (ISS). This giant heart covers an area close to 10 kilometres and is located in Argentina. Although this image looks extremely romantic, the pink heart-shaped structure is the result of a natural occurrence and not symbolic at all….
The warning was always there; scientists are finally starting to understand them. Image Credits: Google Gemini Think about the last time you were under serious pressure. Maybe you calmed down for a minute and then just snapped. Turns out, rocks are pretty much the same. We spent a long time thinking that rocks just broke,…
The sea change that should alarm all of us. Image Credits: Google Gemini Picture this: every winter, like clockwork, cold winds sweep across Central America, stirring up the Pacific Ocean off the coast of Panama. That stirring pulls up cold, nutrient-rich water from the depths, a process called upwelling, and everything that depends on it…
Why do humans fear the dark? How can the science of evolutionary biology explain this primitive instinct? Fear of the dark, an instinctual fear related to the human ability to survive in the natural world, is one that exists firmly in modern psychology. According to evolutionary biology, fear of the dark is an adaptation that…
Quote of the day by Marie Curie (Image source: Wikipedia) People often say that science is a disciplined search for the truth that is based on evidence, observation, and reasoning. But the way people think and act during the process of scientific discovery also affects the results. Marie Curie’s quote of the day, “There are…
In Arizona’s dry, rugged badlands, you can find something far more valuable than any glittering gold: the Petrified Forest. These aren’t just old trees; they’re stone ones, dating back around 225 million years to the Late Triassic period. It happened because of a special chemical change, where volcanic ash and groundwater, full of silica, gradually…
In a quest for a truly self-sustainable source of power, EPFL scientists have explored the hydrovoltaic effect, which makes electricity through the evaporation of water. Through careful engineering of a silicon-based nano-generator, researchers were able to harvest energy from the natural evaporation of seawater to generate electrical power. Unlike existing renewable resources, this innovation can…
