Can I Catch Bird Flu From Eggs or Milk?” A California Expert Explains

With bird flu outbreaks affecting poultry farms and dairies across California, many are questioning the safety of their food. Since highly pathogenic avian influenza (HPAI) appeared in the U.S. in January 2022, it has been found in both wild birds and domestic poultry, as reported by the CDC. Recent Outbreaks of Highly Pathogenic Avian Influenza […]

Greenhouse Gas Concentrations Reach Record Levels as Scientists Raise Concerns

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

The Crop-Spraying Robot Reduces Emissions and Herbicide Use

Robotics, Science / Salomão André

Spraying orchards and vineyards is not environmentally friendly, as tractors emit exhaust while applying herbicides and pesticides. This issue was a key motivation behind the development of the electric, autonomous Prospr robot. Created by the New Zealand agritech firm Robotics Plus, this all-wheel-drive robotic vehicle was introduced last September at the FIRA agricultural robotics show
