Biodegradable 'living plastic' houses bacterial spores that help it break down      (via sciencedaily.com)     Original source 

A new type of bioplastic could help reduce the plastic industry's environmental footprint. Researchers have developed a biodegradable form of thermoplastic polyurethane (TPU) filled with bacterial spores that, when exposed to nutrients present in compost, germinate and break down the material at the end of its life cycle.

A virus could help save billions of gallons of wastewater produced by fracking      (via sciencedaily.com)     Original source 

An estimated 168 billion gallons of wastewater -- or produced water -- is generated annually by the Permian Basin fracking industry, according to a 2022 report. The major waste stream has proved both difficult and costly to treat because of the chemical complexity of the water.

Discovery of mechanism plants use to change seed oil could impact industrial, food oils      (via sciencedaily.com)     Original source 

Researchers have discovered a new mechanism of oil biosynthesis and found a way to genetically engineer a type of test plant to more efficiently produce different kinds of seed oil that it otherwise wouldn't make. While the engineering is proof-of-concept, this discovery could lead to improved production of valuable oils used in food and by a range of industries. The modified plant overcame metabolic bottlenecks and produced significant amounts of an oil similar to castor oil that it doesn't naturally produce.

The longer spilled oil lingers in freshwater, the more persistent compounds it produces      (via sciencedaily.com)     Original source 

Oil is an important natural resource for many industries, but it can lead to serious environmental damage when accidentally spilled. While large oil spills are highly publicized, every year there are many smaller-scale spills into lakes, rivers and oceans. The longer that oil remains in freshwater, the more chemical changes it undergoes, creating products that can persist in the environment.

Warming Arctic reduces dust levels in parts of the planet      (via sciencedaily.com)     Original source 

Dust can have a huge impact on local air quality, food security, energy supply and public health. Previous studies have found that dust levels are decreasing across India, particularly northern India, the Persian Gulf Coast and much of the Middle East, but the reason has remained unclear. Researchers found that the decrease in dust can be attributed to the Arctic warming much faster than the rest of the planet, a phenomenon known as Arctic amplification. This process destabilizes the jet stream and changes storm tracks and wind patterns over the major sources of dust in West and South Asia.

How electric vehicle drivers can escape range anxiety      (via sciencedaily.com)     Original source 

Two of the biggest challenges faced by new and potential electric vehicle (EV) drivers are range anxiety and speed of charging, but these shouldn't have to be challenges at all. Researchers discovered that a change in refueling mindset, rather than improving the size or performance of the battery, could be the answer to these concerns.

Nanofibers rid water of hazardous dyes      (via sciencedaily.com)     Original source 

A special nanostructure has been developed to filter a widespread class of harmful dyes from water. A crucial component is a material that is considered waste: used cellulose, for example in the form of cleaning cloths or paper cups. The cellulose is utilized to coat a fine nano-fabric to create an efficient filter for polluted water.

This salt battery harvests osmotic energy where the river meets the sea      (via sciencedaily.com)     Original source 

Estuaries -- where freshwater rivers meet the salty sea -- are great locations for birdwatching and kayaking. In these areas, waters containing different salt concentrations mix and may be sources of sustainable, 'blue' osmotic energy. Researchers report creating a semipermeable membrane that harvests osmotic energy from salt gradients and converts it to electricity. The new design had an output power density more than two times higher than commercial membranes in lab demonstrations.

Asian monsoon lofts ozone-depleting substances to stratosphere      (via sciencedaily.com)     Original source 

Powerful monsoon winds, strengthened by a warming climate, are lofting unexpectedly large quantities of ozone-depleting substances high into the atmosphere over East Asia, according to new research. The study found that the East Asian Monsoon delivers more than twice the concentration of very short-lived ozone-depleting substances into the upper troposphere and lower stratosphere than previously reported.

'Sunny day flooding' increases fecal contamination of coastal waters      (via sciencedaily.com)     Original source 

A new study finds that 'sunny day flooding,' which occurs during high tides, increases the levels of fecal bacteria in coastal waters. While the elevated bacteria levels in the coastal waters tend to dissipate quickly, the findings suggest policymakers and public health officials should be aware of potential risks associated with tidal flooding.

Laser-treated cork absorbs oil for carbon-neutral ocean cleanup      (via sciencedaily.com)     Original source 

Researchers use laser treatments to transform ordinary cork into a powerful tool for treating oil spills. They tested variations of a fast-pulsing laser treatment, closely examining the nanoscopic structural changes and measuring the ratio of oxygen and carbon in the material, changes in the angles with which water and oil contact the surface, and the material's light wave absorption, reflection, and emission across the spectrum to determine its durability after multiple cycles of warming and cooling. The laser treatments not only help to better absorb oil, but also work to keep water out.
