September is usually a month when the atmospheric concentrations of carbon dioxide (CO2) are at their lowest levels in the northern hemisphere. That’s because plants suck up a lot of the gas as they grow during the summer. But this year, the level of the greenhouse gas has remained stubbornly above the symbolic “red line” of 400 parts per million. This has caused scientists to predict that CO2 levels will not return to environment-friendly levels "ever again for the indefinite future.”

Like most bees, the ground nesting Anthophora squammulosa, that are native to parts of North and Central America, are a solitary species. The females lay their eggs in little underground nests and then head out to search for nectar to feed their developing larvae. This process usually takes place in environments with plenty of flora, to ensure a reliable supply of food.
In 1974, American stuntman Evel Knievel attempted to cross Idaho’s Snake River Canyon aboard a steam-powered rocket. Unfortunately, a parachute deployed prematurely and caused the rocket and its occupant to drift to the canyon’s bottom. While Knievel emerged relatively unscathed from the incident, he never got a chance to attempt the stunt again.
Monday, August 8, was Earth Overshoot Day. Calculated annually by the environmental advocacy group, Global Footprint Network, it is the day when humanity has consumed all the natural resources — produce, meat, fish, water, and wood — that our planet can regenerate in a single year. This means that for the rest of 2016, we will be using natural resources that are impossible to replace.
Water, or rather the lack of it, is one of the most pressing issues of our times. Unprecedented droughts and growing populations have left many countries struggling to keep up with demand. Given that agriculture is the largest single user of freshwater, providing farmers with new conservation techniques would go a long way in alleviating our water woes. It turns out that a “miracle” powder has been helping drought-stricken Mexican farmers do exactly that for over a decade!
Any member of the five species of the Prasinohaema (Greek: “green blood”) skinks that that live on the island of New Guinea in the South West Pacific, would have been a shoo-in for J.K. Rowling’s wildly imaginative Harry Potter book series. That’s because besides being the only known land vertebrates to have “vivid lime green” blood, the reptiles also sport green bones, green muscles, and even a green tongue!
The Pallas’s cat is a small-sized wild cat species that lives in the remote steppes and mountains of Central Asia. Excessive hunting of the animals that are coveted for their thick, lush, fur as well as the loss of habitat has drastically reduced their numbers in the wild. As a result, the beautiful animals have been on IUCN’s near threatened list of species since 2002. It is, therefore, no wonder that the recent sighting of the elusive cats in the mountains of Mongolia is causing such joy among conservationists and cat lovers worldwide.
At the end of the spring semester in May, students taking Georgia Tech’s online Knowledge-Based Artificial Intelligence course received some stunning news. Jill Watson, one of the nine teaching assistants (TA’s) that had helped them navigate the challenging course for the past five months was not a “she,” but an “it” — an intelligent robot to be precise!
