At one of Europe's largest chemical complexes, German group Covestro is trialing the manufacture of a key product using sugar as a base material instead of oil, as the industry seeks to reduce its carbon footprint.

Uncover the fascinating world of mealworms! Dive deep into their life cycle, uses, and why they're more important than you think.

The question may sound like a "duh," but it gets to the heart of how we categorize and define nature

It's easy to mistake a crow for a raven or vice versa. But the two birds are actually pretty different.

Nurse Shark Ginglymostoma cirratum These bottom dwelling sharks are usually yellowish-tan to dark brown and, as adults, average around 7.5 to 8 feet long and over 200 pounds (Rosa et al. 2006). They are nocturnal, scouting the sea bottom for crustaceans, mollusks and stingrays during the nig

Odd things can happen when a wave meets a boundary. In the ocean, tsunami waves that are hardly noticeable in deep water can become quite large at the continental shelf and shore, as the waves slow and their mass moves upward.

Clocks will "spring forward" when daylight saving time begins on Sunday, March 10, 2024.

There are some really cute insects out there, and one genus of especially cute insects is the genus Euspinolia, called the Panda Ants. Panda Ants are actually not ants at all, but instead are wasps…

A new approach to grid planning could make it possible to power your home with the nation's best and lowest-cost wind and solar energy, no matter where you live.

The push for renewable energy is critical in addressing climate change, with wind power at the forefront. As the leading emitter of greenhouse gases, China has embarked on a transformative journey towards greener alternatives, aiming for carbon neutrality by 2060.

Historically, photovoltaic (PV) modules have demonstrated high reliability, making them a dependable and growing part of global decarbonization efforts. PV module technology also has a history of iteration and evolution over time, with potential impacts for module reliability.

A research team led by Professor Seok Ju Kang in the School of Energy and Chemical Engineering at UNIST has unveiled a technique for mass-producing polymer solid electrolytes, crucial components in batteries. Their paper is published in the journal Energy Storage Materials.

Schools of fish, colonies of bees, and murmurations of starlings exhibit swarming behavior in nature, flowing like a liquid in synchronized, shape-shifting coordination. Through the lens of fluid mechanics, swarming is of particular interest to physicists like Heinrich Jaeger, the University of Chicago Sewell Avery Distinguished Service Professor in Physics and the James Franck Institute, and James Franck Institute research staff scientist Baudouin Saintyves, who apply physics principles to the development of modular, adaptive robotics.

Peripheral vision enables humans to see shapes that aren't directly in our line of sight, albeit with less detail. This ability expands our field of vision and can be helpful in many situations, such as detecting a vehicle approaching our car from the side.

When you teach a child how to solve puzzles, you can either let them figure it out through trial and error, or you can guide them with some basic rules and tips. Similarly, incorporating rules and tips into AI training—such as the laws of physics—could make them more efficient and more reflective of the real world. However, helping the AI assess the value of different rules can be a tricky task.

Adhesive tape or sticky notes are easy to attach to a surface, but are difficult to remove. This phenomenon, known as adhesion hysteresis, can be fundamentally observed in soft, elastic materials: Adhesive contact is formed more easily than it is broken.

The Wet Tropics World Heritage Area is a living natural wonder and a cultural landscape like nowhere else on earth. It hugs the coastal fringes from Townsville to Cairns like a long green ribbon.

The rapid advancement in machine learning techniques and sensing devices over the past decades have opened new possibilities for the detection and tracking of objects, animals, and people. The accurate and automated detection of visual targets, also known as intelligent machine vision, can have various applications, ranging from the enhancement of security and surveillance tools to environmental monitoring and the analysis of medical imaging data.

Metals can be processed into wires by cold forming—an extremely complex process. However, the lubricants needed for this often do not meet the requirements of the end processors.

The energy transition is progressing, and photovoltaics (PV) is playing a key role in this. Enormous capacities are to be added over the next few decades. Experts expect several tens of terawatts by the middle of the century. That's 10 to 25 solar modules for every person. The boom will provide clean, green energy. But this growth also has its downsides.
