Efficient biohybrid batteries      (via sciencedaily.com)     Original source 

Formic acid, which can be produced electrochemically from carbon dioxide, is a promising energy carrier. A research team has now developed a fast-charging hybrid battery system that combines the electrochemical generation of formic acid as an energy carrier with a microbial fuel cell. This novel, fast-charging biohybrid battery system can be used to monitor the toxicity of drinking water, just one of many potential future applications.

Humans are disrupting natural 'salt cycle' on a global scale, new study shows      (via sciencedaily.com)     Original source 

A new paper revealed that human activities are making Earth's air, soil and freshwater saltier, which could pose an 'existential threat' if current trends continue. Geologic and hydrologic processes bring salts to Earth's surface over time, but human activities such as mining and land development are rapidly accelerating this natural 'salt cycle.'

Soy expansion in Brazil linked to increase in childhood leukemia deaths      (via sciencedaily.com)     Original source 

Brazil's rapid expansion of soy production has meant an associated rise in pesticide use. Researchers found a statistically significant correlation between soy expansion and acute lymphoblastic leukemia (ALL) deaths in children between 2008 and 2019, representing the first population-wide analysis of the association between indirect exposure to agricultural pesticides and cancer.

Gaming strategy helps plan for and prevent attacks on infrastructure      (via sciencedaily.com)     Original source 

As technology continues to advance, the likelihood of malevolent attacks and subsequent failures on society's critical infrastructures increases. Blackouts, water shortages, transport collapses -- these potential threats to cities not only come with a hefty price tag but are likely to cause chaos and affect the health and safety of communities. UBC Okanagan Postdoctoral Research Fellow Dr. Amin Ahmadi Digehsara, along with Assistant Professor Dr. Amir Ardestani-Jaafari, both with the Faculty of Management, recently published a study that will enhance the resilience of vital infrastructures against malevolent attacks.

Cold War spy satellite imagery reveals Ancient Roman forts      (via sciencedaily.com)     Original source 

A new study analyzing declassified Cold War satellite imagery reveals 396 previously undocumented Roman forts and reports that these forts were constructed from east to west, spanning from what is now western Syria to northwestern Iraq. The analysis refutes Father Antoine Poidebard's claim that the forts were located along a north-south axis.

Tracking down environmental toxins      (via sciencedaily.com)     Original source 

PFAS, a family of highly fluorinated substances, represent a danger for humans and the environment. Particularly problematic members of this family, such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) appear to cause organ damage and cancer, as well as disrupting the endocrine system. Researchers have now introduced a new method for an economical, easy-to-use fluorescence sensor for sensitive on-site testing for PFAS in water samples.

The race of water droplets      (via sciencedaily.com)     Original source 

How fast does a droplet flow along a fiber? It depends on the diameter of the fiber... and also on its substructure! These are the findings of a study conducted by researchers who are interested in microfluidics, especially water harvesting in arid/semi-arid regions of our planet.

Mystery of volcanic tsunami solved after 373 years      (via sciencedaily.com)     Original source 

The explosion of the underwater volcano Kolumbo in the Aegean Sea in 1650 triggered a destructive tsunami that was described by historical eye witnesses. A group of researchers has now surveyed Kolumbo's underwater crater with modern imaging technology and reconstructed the historical events. They found that the eyewitness accounts of the natural disaster can only be described by a combination of a landslide followed by an explosive eruption.

Do or dye: Synthetic colors in wastewater pose a threat to food chains worldwide      (via sciencedaily.com)     Original source 

Dyes widely used in the textile, food and pharmaceutical industries pose a pressing threat to plant, animal and human health, as well as natural environments around the world, a new study has found. Billions of tons of dye-containing wastewater enter water systems every year, and a group of researchers say that new sustainable technologies including new membrane-based nano-scale filtration are needed to solve the issue, adding that legislation is needed to compel industrial producers to eliminate colorants before they reach public sewage systems or waterways.

To navigate the world, we all shimmy like these electric fish      (via sciencedaily.com)     Original source 

An electric knifefish shimmies in the water for the same reason a dog sniffs or a human glances around a new place -- to make sense of their surroundings. For the first time, scientists demonstrate that a wide range of organisms, even microbes, perform the same pattern of movements in order to sense the world.

On the trail of the silver king: Researchers reveal unprecedented look at tarpon migration      (via sciencedaily.com)     Original source 

New research unveils a dataset, gathered over five years, that gives the finest-grained detail into the timing and spatial extent of tarpon migration. The work leveraged networks of thousands of acoustic receivers that tracked 200 tarpon over more than five years. One of the key findings is that there are two distinct subgroups of tarpon, which has immediate implications for efforts to conserve the fish, known to anglers as the 'Silver King.'

Diapers can be recycled 200 times faster with light      (via sciencedaily.com)     Original source 

More than 100,000 tons of diapers are disposed of annually in Germany. Vast amounts of valuable resources, such as diaper liners, end up in the trash. The liners consist of special polymers, so-called superabsorbers. Researchers have now succeeded in considerably improving their complex recycling process. They use UV radiation to degrade the chemical chains that keep the polymers together. No chemicals are needed. Recycling at room temperature is 200 times faster than conventional recycling. The recycled polymers can then be processed to new adhesives and dyes.
