Nuclear Fusion vs. Fission: A Physicist Clarifies the Distinction

Nuclear power generates about 10% of the world’s electricity, with countries like France relying on it for nearly 70%. Tech giants like Google are also turning to nuclear energy to power their demanding data centers. The energy for nuclear power comes from atomic binding energy, released through two primary processes: fission and fusion. Fission splits […]

Why We Kiss: A New and Intriguing Theory That Predates Human Life on Earth

Biology / Evelina Jeremias

The Origins of Kissing Most of us kiss at some point, whether romantically, with family, friends, or formally. However, the origin of this behavior and how it emerged among humans remain subjects of intense debate among historians and anthropologists. A new theory suggests that the evolutionary loss of body hair could be at the root

Plant-Animal Hybrid Cells Create Solar-Powered Tissues, Organs, Or Meat

Biology, Science / Ngoma Manuel

Hybrid Plant-Animal Cells Developed in Japan Scientists in Japan have developed hybrid plant-animal cells, allowing animal cells to harness energy from sunlight like plants. This innovation could bring significant benefits for growing organs and tissues for transplant, as well as lab-grown meat. Animal and plant cells have different structures for energy production. In animals, this

Greenhouse Gas Concentrations Reach Record Levels as Scientists Raise Concerns

Earth Science, Environmental Science / Ngoma Manuel

In 2023, greenhouse gas concentrations in the atmosphere hit new record highs, ensuring future temperature rises for years ahead, the United Nations cautioned on Monday. The levels of the three primary greenhouse gases—carbon dioxide, methane, and nitrous oxide, which contribute to climate warming—have all risen once more over the past year, according to the UN’s

High School Students Publish Impossible Proofs of Pythagoras Theorem

Physics / Salomão André

What started as a bonus question in a high school math competition has led to an astonishing 10 new proofs of the ancient Pythagorean theorem. It has long been considered impossible to use trigonometry to demonstrate a theorem that is foundational to trigonometric principles, as this creates a logical fallacy of circular reasoning by attempting

Front-Loading Exoskeleton Helps Paralyzed Patients Walk

Robotics, Science / Jorge Paka

Exoskeletons have assisted paraplegic patients in walking for years, but KAIST’s latest model offers a unique approach. The WalkON Suit F1 can move up to a patient in a wheelchair, secure itself around their legs and torso, and help them stand and walk. Professor Kyoung-Chul Kong of KAIST’s Department of Mechanical Engineering has focused on

Miracle Powder Removes CO2 from the Air More Effectively than Any Other Solution

Earth Science, Environmental Science / Valeriano Ndeyi

Researchers at the University of California, Berkeley have developed a powdery material that adsorbs carbon dioxide with remarkable efficiency. Just 200 grams (about 0.5 pounds) can capture 44 pounds (20 kilograms) of CO2, equivalent to what a tree absorbs in a year. It’s known as COF-999, short for Covalent Organic Frameworks. This term describes a
