Scientists examining microplastic particles in a laboratory sample

How Scientists Track Microplastics That Are Too Small to See

Plastic pollution is no longer limited to bottles, bags, and packaging floating in rivers or washing up on beaches. Much of it breaks into particles so small that they cannot be seen with the naked eye. These tiny fragments, known as microplastics and nanoplastics, have become an important subject of scientific research because they can

Antarctic plant growth emerging across ice-free areas of the Antarctic Peninsula

Antarctic Ice Reveals Earth’s Accelerating Plant Growth

Antarctica is one of the coldest and most isolated places on Earth. For most people, its landscape brings to mind enormous ice sheets, glaciers, snow-covered mountains, and powerful winds. Yet beneath that frozen image, something surprisingly different is happening. In parts of Antarctica, especially around the Antarctic Peninsula, vegetation is becoming more noticeable as environmental

Jupiter photographed by NASA spacecraft showing its colorful cloud bands and massive storms

Photos of Jupiter From NASA Spacecraft, Both Near and Far

Jupiter is easy to recognize in the night sky, but seeing it through a spacecraft camera is a completely different experience. From far away, the planet looks like a bright, striped sphere floating in the darkness. Get closer, however, and those familiar stripes turn into enormous clouds, swirling storms, and constantly changing patterns. NASA spacecraft

Science bots on Twitter helping users discover research and scientific content

6 Bots That Deliver Science and Serendipity on Twitter

Traditional research often starts with a specific question. You choose a topic, enter keywords into a search engine or research database, and review the results. Science bots introduce a different approach: discovery without a predefined search. A useful post can appear while you are browsing something completely unrelated. That unexpected encounter may introduce a new

Hans Dehmelt, Nobel Prize-winning physicist who pioneered single-electron trapping

Hans Dehmelt, Nobel Laureate for Isolating Electrons, Dies at 94

What would it take to study a single electron? It sounds like a straightforward question, but for physicists, isolating one of the smallest known particles and observing its behavior is an extraordinary experimental challenge. Electrons are incredibly small, electrically charged and constantly influenced by their surroundings. For much of modern scientific history, researchers had to
