Physicists explore a new recipe for heating plasma

In the quest for fusion energy, scientists have spent decades experimenting with ways to make plasma fuel hot and dense enough to generate significant fusion power. At MIT, researchers have focused their attention on using radio-frequency (RF) heating in magnetic confinement fusion experiments like the Alcator C-Mod tokamak, which completed its final run in September 2016.

Researchers explore new chapter of physics

Interactions between light and matter are a fundamental unit of modern physics, but recently researchers have started to look beyond the standard textbook interactions.

Engineers predict how flowing fluid will bend tiny hairs that line blood vessels and intestines

Our bodies are lined on the inside with soft, microscopic carpets of hair, from the grassy extensions on our tastebuds, to fuzzy beds of microvilli in our stomachs, to superfine protein strands throughout our blood vessels. These hairy projections, anchored to soft surfaces, bend and twist with the currents of the fluids they're immersed in.

It's an exciting day today! Please don't lock your kids away, which seems to be an alarmingly common option (from looking at the news - many schools seem to be opting to do that; I wish they'd use they use some of those locked classrooms as camera obscura). Show More Summary

Physicists resolve long-standing mystery of structure-less transition

Nagoya University-led team of physicists use a synchrotron radiation X-ray source to probe a so-called "structure-less" transition and develop a new understanding of molecular conductors.

New technology to capture live cell images opening new possibilities to the study of cell biology

Researchers at The Hong Kong University of Science and Technology (HKUST) have developed a new generation of microscope, which not only could capture 3D live cell videos, but the resulted images are also of much higher quality, greatly enhancing the accuracy and the scope of research on cell biology.

Scientists accelerate airflow in mid-air

When a fan blows air across a room, the airflow typically decelerates and spreads out. Now in a new study, scientists have demonstrated the opposite: an airflow created by a carefully controlled ultrasound array can maintain its narrow shape and accelerate as it moves away from the source.

Avoiding disruptions that halt fusion reactions

Inside a fusion experiment, where scientists study the reactions at the heart of our sun, disruptions—large-scale instabilities of the plasma—cause rapid and complete loss of magnetic confinement. Models of fusion plasmas now combine advanced numerical methods with high-performance computing capabilities. Show More Summary

3-D particle tracking? There's an app for that

Using four low-cost smartphone cameras and some simple colored backlighting, KAUST researchers have dispensed with expensive research-grade camera equipment and dangerous lasers to construct a tomographic particle image velocimetry (PIV) system that is capable of quantitative flow visualization.

How heating up a quantum system can be used as a universal probe for exotic states of matter

In physical sciences, certain quantities appear as integer multiples of fundamental and indivisible elements. This quantization of physical quantities, which is at the heart of our description of nature, made its way through the centuries, as evidenced by the antique concept of the atom. Show More Summary

Nanomaterial wrap for improved tissue imaging

Researchers at Tokai University describe in Advanced Materials how wrapping biological tissue in a nanosheet of a particular organic material results in high-quality microscopy images. Application of the wrap prevents the sample from drying out, and hence from shrinking, enabling larger image-recording times.

A quick and easy way to shut down instabilities in fusion devices

Scientists have discovered a remarkably simple way to suppress a common instability that can halt fusion reactions and damage the walls of reactors built to create a "star in a jar." The findings, published in June in the journal Physical...Show More Summary

Engineers deliver new key components to help power a fusion energy experiment

Fusion power, which lights the sun and stars, requires temperatures of millions of degrees to fuse the particles inside plasma, a soup of charged gas that fuels fusion reactions. Here on Earth, scientists developing fusion as a safe,...Show More Summary
