Long-anticipated experiments that use light to mimic gravity are revealing the distribution of energies, forces, and pressures inside a subatomic particle for the first time.

Voids, or empty spaces, exist within matter at all scales, from the astronomical to the microscopic. In a new study, researchers used high-powered microscopy and mathematical theory to unveil nanoscale voids in three dimensions. This advancement is poised to improve the performance of many materials used in the home and in the chemical, energy and medical industries—particularly in the area of filtration.

Magnification of common filters used in the home shows that, while they look like a solid piece of material with uniform holes, they are actually composed of millions of randomly oriented tiny voids that allow small particles to pass through. In some industrial applications, like water and solvent filtration, paper-thin membranes make up the barriers that separate fluids and particles.

“The materials science community has been aware of these randomly oriented nanoscale voids within filter membranes for a while,” said Falon Kalutantirige, a University of Illinois Urbana-Champaign graduate student.

Researchers from the RIKEN Center for Emergent Matter Science and collaborators have developed an organic photovoltaic film that is both waterproof and flexible, allowing a solar cell to be put onto slothes and still function correctly after being rained on or even washed.

One of the potential uses of organic photovoltaics is to create wearable electronics — devices that can be attached to clothing that can monitor medical devices, for example, without requiring battery changes.

However, researchers have found it challenging to achieve waterproofing without the use of extra layers that end up decreasing the flexibility of the film.

St. Jude Children’s Research Hospital scientists reversed an aggressive cancer, reverting malignant cells towards a more normal state. Rhabdoid tumors are an aggressive cancer which is missing a key tumor suppressor protein. Findings showed that with the missing tumor suppressor, deleting or degrading the quality control protein DCAF5 reversed the cancer cell state. These results suggest a new approach to curing cancer — returning cancerous cells to an earlier, more normal state rather than killing cancer cells with toxic therapies — may be possible. The results were published today in Nature.

“Rather than making a toxic event that kills rhabdoid cancer, we were able to reverse the cancer state by returning the cells toward normal,” said senior author Charles W.M. Roberts, MD, PhD, Executive Vice President and St. Jude Comprehensive Cancer Center director. “This approach would be ideal, especially if this paradigm could also be applied to other cancers.”

“We found a dependency which actually reverses the cancer state,” said first author Sandi Radko-Juettner, PhD, a former St. Jude Graduate School of Biomedical Sciences student, now a Research Program Manager for the Hematological Malignancies Program at St. Jude. “Standard cancer therapies work by causing toxicities that also damage healthy cells in the body. Here, it appears that we’re instead fixing the problem caused by the loss of a tumor suppressor in this rhabdoid cancer.”

Gateways between stars, wormholes through the fabric of reality, but could these be real, and if so, what would the civilizations using them be like?

Hyperjumps, wormholes, and warp drives sound like science fiction, but they’re actually based on real science! Though I believe out of the three, warp drives are the most plausible. The math seems to agree. Today I want to tell you about a new way of analysing and visualizing warp drives.
