The artistic representation illustrates a measurement of a beam in a particle accelerator, demonstrating the beam’s structural complexity increases when measured in progressively higher dimensions. Each increase in dimension reveals information that was previously hidden.

The first full characterization measurement of an accelerator beam in six dimensions will advance the understanding and performance of current and planned accelerators around the world. A team of researchers led by the University of Tennessee, Knoxville conducted the measurement in a beam test facility at the Department of Energy’s Oak Ridge National Laboratory using a replica of the Spallation Neutron Source’s linear accelerator, or linac...

This deep image of the area of sky around the elliptical galaxy NGC 5018 offers a spectacular view of its tenuous streams of stars and gas. These delicate features are hallmarks of galactic interactions, and provide vital clues to the structure and dynamics of early-type galaxies.

A glittering host of galaxies populate this rich image taken with ESO’s VLT Survey Telescope, a state-of-the-art 2.6-m telescope designed for surveying the sky in visible light. The features of the multitude of galaxies strewn across the image allow astronomers to uncover the most delicate details of galactic structure.

Whereas ESO’s Very Large Telescope (VLT) can observe very faint astronomical objects in great detail, when astronomers want to understand how the huge variety of galaxies...

HSP-specific T cells infiltrate the retinas and augment glaucomatous neurodegeneration

Unexpected findings show that the body’s own immune system destroys retinal cells. A new study from MIT and Massachusetts Eye and Ear has found that glaucoma may in fact be an autoimmune disorder. In a study of mice, the researchers showed that the body’s own T cells are responsible for the progressive retinal degeneration seen in glaucoma. Furthermore, these T cells appear to be primed to attack retinal neurons as the result of previous interactions with bacteria that normally live in our body.

The discovery suggests that it could be possible to develop new treatments for glaucoma by blocking this autoimmune activity, the researchers say...

For the first time, the researchers from MIT and AFFOA have produced fibers with embedded electronics that are so flexible they can be woven into soft fabrics and made into wearable clothing.

Researchers incorporate optoelectronic diodes into fibers and weave them into washable fabrics. The latest development in textiles and fibers is a kind of soft hardware that you can wear: cloth that has electronic devices built right into it. Researchers at MIT have now embedded high speed optoelectronic semiconductor devices, including light-emitting diodes (LEDs) and diode photodetectors, within fibers that were then woven at Inman Mills, in South Carolina, into soft, washable fabrics and made into communication systems...
