A team of experimentalists at the U.S. Department of Energy’s Ames Laboratory and theoreticians at University of Alabama Birmingham discovered a remarkably long-lived new state of matter in an iron pnictide superconductor, which reveals a laser-induced formation of collective behaviors that compete with superconductivity.
Scientists have created a rubbery, shape-shifting material that morphs from one sophisticated form to another on demand.
The shapes programmed into a polymer appear in ambient conditions and melt away when under heat. The process also works in reverse.

A new Tel Aviv University study describes a process to make bioplastic polymers that don’t require land or fresh water—resources that are scarce in much of the world. The polymer is derived from microorganisms that feed on seaweed. It is biodegradable, produces zero toxic waste and recycles into organic waste.
The invention was the fruit of a multidisciplinary collaboration between Dr. Alexander Golberg of TAU’s Porter School of Environmental and Earth Sciences and Prof. Michael Gozin of TAU’s School of Chemistry. Their research was recently published in the journal Bioresource Technology.
According to the United Nations, plastic accounts for up to 90 percent of all the pollutants in our oceans, yet there are few comparable, environmentally friendly alternatives to the material.
Astronomers have spotted a monstrous stellar flare coming from a baby star 685 light-years away that’s estimated to be 10,000 times larger than any such event emitted by our sun.
Experts say the stellar ‘tantrum’ could provide a window into the birth of potentially habitable exoplanets, revealing how huge events shake up the material orbiting distant stars.

Keeping passengers in a vehicle from hearing the noise of a busy road is a problem that many auto manufacturers have attempted to solve over the years. Noise dampening materials can only do so much, but Ford is now working with noise cancelling technologies that aim to actively combat road sounds by cancelling them out.
The company recently applied its new noise-cancelling know-how to a project that has nothing to do with vehicles, but instead focuses on man’s best friend. Ford Europe built a new kind of doghouse that allows canines to rest without worry of loud noises, like fireworks, disturbing them.
Scientists have long known that synthetic materials—called metamaterials—can manipulate electromagnetic waves such as visible light to make them behave in ways that cannot be found in nature. That has led to breakthroughs such as super-high resolution imaging. Now, UMass Lowell is part of a research team that is taking the technology of manipulating light in a new direction.
