The yuck factor counteracts sustainable laundry habits      (via sciencedaily.com)     Original source 

Most people today would lean towards environmentally friendly life choices, but not at the expense of being clean. When it comes to our washing habits, the fear of being perceived as dirty often wins out over the desire to act in an environmentally friendly way. And the more inclined we are to feel disgusted, the more we wash our clothes. This is shown by a unique study that examines the driving forces behind our laundering behaviours and provides new tools for how people's environmental impact can be reduced.

Scientists unravel drivers of the global zinc cycle in our oceans, with implications for a changing climate      (via sciencedaily.com)     Original source 

The understanding of the global zinc cycle in our oceans has important implications in the context of warming oceans. A warmer climate increases erosion, leading to more dust in the atmosphere and consequently more dust being deposited into the oceans. More dust means more scavenging of zinc particles, leading to less zinc being available to sustain phytoplankton and other marine life, thereby diminishing the oceans' ability to absorb carbon.

Ancient ocean slowdown warns of future climate chaos      (via sciencedaily.com)     Original source 

When it comes to the ocean's response to global warming, we're not in entirely uncharted waters. A new study shows that episodes of extreme heat in Earth's past caused the exchange of waters from the surface to the deep ocean to decline.

Dolphins with elevated mercury levels in Florida and Georgia      (via sciencedaily.com)     Original source 

Scientists found elevated mercury levels in dolphins in the U.S. Southeast. The highest levels were found in dolphins in Florida's St. Joseph and Choctawhatchee Bays. Researchers study dolphins because they are considered a sentinel species for oceans and human health. Like us, they are high up in the food chain, live long lives, and share certain physiological traits. Some of their diet is most vulnerable to mercury pollution and is also eaten by people.

Western agricultural communities need water conservation strategies to adapt to future shortages      (via sciencedaily.com)     Original source 

The Western U.S. is heavily reliant on mountain snowpacks and their gradual melt for water storage and supply, and climate change is expected to upend the reliability of this natural process. Many agricultural communities in this part of the country are examining ways to adapt to a future with less water, and new research shows that a focus on supplementing water supply by expanding reservoir capacity won't be enough to avert future water crises.

Swimming microrobots deliver cancer-fighting drugs to metastatic lung tumors in mice      (via sciencedaily.com)     Original source 

Engineers have developed microscopic robots, known as microrobots, capable of swimming through the lungs to deliver cancer-fighting medication directly to metastatic tumors. This approach has shown promise in mice, where it inhibited the growth and spread of tumors that had metastasized to the lungs, thereby boosting survival rates compared to control treatments.

Mobile monitoring for an airborne carcinogen in Louisiana's 'Cancer Alley'      (via sciencedaily.com)     Original source 

Louisiana's southeastern corridor is sometimes known colloquially as 'Cancer Alley' for its high cancer incidence rates connected to industrial air pollution. Most of the region's air pollution-related health risks are attributed to ethylene oxide, a volatile compound used to make plastics and sterilize medical equipment. Researchers measured concerning levels of ethylene oxide in this area with mobile optical instruments, a technique they say could improve health risk assessments.

From seashells to cement, nature inspires tougher building material      (via sciencedaily.com)     Original source 

Inspired by the material that makes up oyster and abalone shells, engineers have created a new cement composite that is 17 times more crack-resistant than standard cement and 19 times more able to stretch and deform without breaking. The findings could eventually help increase the crack resistance of a wide range of brittle ceramic materials from concrete to porcelain.

Trash-sorting robot mimics complex human sense of touch      (via sciencedaily.com)     Original source 

Researchers are breaking through the difficulties of robotic recognition of various common, yet complex, items. Their layered sensor is equipped with material detection at the surface and pressure sensitivity at the bottom, with a porous middle layer sensitive to thermal changes. An efficient cascade classification algorithm rules out object types in order, from easy to hard, starting with simple categories like empty cartons before moving on to orange peels or scraps of cloth.
