"Rocks store information about the temperatures that they have experienced. Now, for the first time, researchers have developed a method that reveals low-temperature information (from 35 °C and higher) on a relatively short timescale of thousands of years. The new method might find application in locating geothermal reservoirs and in maintaining underground tunnels".

"Tiny microscopic animals called zooplankton are ingesting plastic particles at an alarming rate, according to a new study. That could not only pose a risk to salmon but also spell trouble for the entire aquatic food web -- from zooplankton to humpback whales".

Shows how much I know about this stuff: my first thought was, "Oh good!"

"Geologists have found evidence of helium leakage from Earth's mantle along a 30-mile stretch of the Newport-Inglewood Fault Zone in the Los Angeles Basin. Using samples of casing gas from two dozen oil wells ranging from LA's Westside to Newport Beach in Orange County, researchers discovered that more than one-third of the sites -- some of the deepest ones -- show evidence of high levels of helium-3 (3He)".

"The brown marmorated stink bug has a bad reputation. Every summer, this pest attacks crops and invades homes, causing both sizable economic losses and a messy, smelly nuisance. A new study by entomologists shows that these pests, known simply as stink bugs, have a strong preference for ripe fruit. Moreover, stink bugs track their favorite fruits throughout the growing season in an effort to maximize their access to food".

"One of the world’s rarest big cat species has received some much-needed good news this month. According to newly published surveys, the population of endangered Asiatic lions (Panthera leo persica) has experienced a population boom to a modern-day high of 523. That’s a 27 percent increase over the population of 411 cats during the previous survey five years ago.
Asiatic lions—also known as Gir lions because they live only in and around the Gir National Park and Wildlife Sanctuary in Gujarat, India—were hunted to near-extinction in the 19th century. All of today’s Asiatic lions are descended from just 13 cats, which were protected at the last minute in 1907 by an Indian prince. The cats are the only lion subspecies that lives outside of Africa.
Gir lions continue to face multiple threats despite more than a century of protection. Millions of people live in and around the national park, and the lions often end up in conflict with humans and livestock. They also have been known to fall into wells or get electrocuted on bare-wire, high-power fences. Young lions are also wandering farther out of the park to find their own territories. This dispersal puts the cats outside of the sanctuary’s protection, and they increasingly find themselves being hit by passing cars, trucks or trains. During the past year some have even been observed 100 kilometers outside the park in densely populated human neighborhoods".

"It's been difficult to explain patterns of toxic mercury in some parts of the world, such as why there's so much of the toxin deposited into ecosystems from the air in the southeastern United States, even upwind of usual sources. Now, a new analysis shows that one key to understanding mercury's strange behavior may be the unexpected reactivity of naturally occurring halogen compounds from the ocean".

"In the human body, small wounds are easily treated by the body itself, requiring no further care. For bigger wounds to be healed, the body may need outside assistance. Concrete is like a living body, in that it can self-heal its own small wounds (cracks) as an intrinsic characteristic".

"New scientific research could help to protect tigers (Panthera tigris) from extinction. The findings indicate that tigers should be classified as only two subspecies – up to now nine subspecies were previously recognized. This will have a significant impact on species conservation since management efforts and breeding programs can now be organized in a simpler, more flexible and effective way".
