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.
Interactions between light and matter are a fundamental unit of modern physics, but recently researchers have started to look beyond the standard textbook interactions.
Flash Physics: need-to-know updates from the world of physics
Refractive-index gradient reduces spherical aberration
A new cryogenic facility provides a place for superconducting magnet tests before the Mu2e detector is assembled.
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.
Conference: 9 Nov 2017 - 10 Nov 2017, Saarbrücken, Germany. Organized by INM - Leibniz Institute of New Materials.
School: 26 Feb 2018 - 2 Mar 2018, Dresden, Germany. Organized by André Eckardt, Fabian Heidrich-Meisner, Christof Weitenberg.
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
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.
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.
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.

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
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.

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
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.
Lead-ion collisions reveal phenomenon forbidden in classical physics
A new approach to optical imaging makes it possible to quickly and economically monitor multiple molecular interactions in a large area of living tissue—such as an organ or a small animal; technology that could have applications in medical diagnosis, guided surgery, or pre-clinical drug testing.

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
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
