Gold mining with mercury poses health threats for miles downstream  

Small-scale gold mining in the Peruvian Amazon poses a health hazard not only to the miners and communities near where mercury is used to extract gold from ore, but also to downstream communities hundreds of kilometers away where people eat mercury-contaminated river fish as part of their diet. Downstream children under 12 with the highest levels of mercury in their bodies were found to have lost IQ points and become anemic.

Researchers have now found a method that might make the production of a biologically significant precursor of jasmonic acid more efficient and cheaper. Their innovation: they imitate how plants produce the hormone. The result is 12-OPDA, a central precursor of jasmonic acid. In the long term, it could also be a potential precursor for high-quality perfume.

A bio-inspired addition to concrete stops the damage caused by freezing and thawing  

Concrete is one of the most durable building materials used in modern-day infrastructures, but it has a weakness -- ice -- which can cause it to crumble. Now, inspired by organisms that survive in sub-zero environments, researchers are introducing polymer molecules with anti-freezing abilities into concrete.

Under pressure, black holes feast  

A new study shows that some supermassive black holes actually thrive under pressure. It has been known for some time that when distant galaxies -- and the supermassive black holes within their cores -- aggregate into clusters, these clusters create a volatile, highly pressurized environment. Individual galaxies falling into clusters are often deformed during the process and begin to resemble cosmic jellyfish.

Computer vision and uncertainty in AI for robotic prosthetics  

Researchers have developed new software that can be integrated with existing hardware to enable people using robotic prosthetics or exoskeletons to walk in a safer, more natural manner on different types of terrain. The new framework incorporates computer vision into prosthetic leg control, and includes robust artificial intelligence (AI) algorithms that allow the software to better account for uncertainty.

Winds spread PFAS pollution far from a manufacturing facility  

Concerns about environmental and health risks of some fluorinated carbon compounds used to make non-stick coatings and fire-fighting foams have prompted manufacturers to develop substitutes, but these replacements are increasingly coming under fire themselves. To get a handle on the scope of the problem, scientists have been studying how widely these chemicals have contaminated the environment. Now, researchers report that, in one case, they have dispersed more broadly than previously realized.

Modern problems, primitive solutions: A glimpse into archaic protein synthesis systems  

The interaction between 'transfer RNAs' and the enzymes that help them in protein synthesis has always been the key area of interest for understanding the evolution of the genetic code. Now, a team of scientists reports that a subunit of 'alanyl-tRNA synthetase' enzyme of the primitive microorganism Nanoarchaeum equitans can mimic the super-primitive tRNA 'aminoacylation' independent of the presence of a special 'G3:U70' base pair, a property previously unseen in primitive organisms.

Designing a flexible material to protect buildings, military personnel  

Shake, rattle and roll. Even though they are miles from the epicenter of an earthquake, buildings can collapse due to how an earthquake energy makes the ground shake and rattle. Now, a team of engineers has designed a flexible material that can help buildings withstand multiple waves of energy traveling through a solid material, including the simultaneous forward and backward and side-to-side motions found in earthquakes.
