September is wrapping up, and we’ve got your monthly STEM news! Here are some of our favorite stories.
Researchers have discovered a brand new species of poison dart frog in Donoso, Panama. At 12.7 millimeters in length, the freshly dubbed Andinobates geminisae is tiny enough to fit on a fingernail and is distinguishable by its unique call and smooth, bright orange-colored skin. Scientists believe that habitat loss is a significant issue of concern for these newly found frogs, as it appears to only be found in scarce regions of the Panama rain forest. To guarantee the survival of their species, the creation of special conservation plans have been recommended. Read more here.
Several groups of fish in Antarctica have developed the ability to manufacture their own “antifreeze” proteins in their blood that help them survive in the icy Southern Ocean. Unfortunately, it appears that this evolutionary survival tactic has created some undesirable consequences. Researchers have discovered that the same temperature regulation proteins are helping internal ice crystals that accumulate inside the fish resist melting, even when the temperatures warm.

At least 36 people have been killed following the unanticipated eruption of Mount Ontake, Japan’s second largest active volcano. The eruption is believed to have stemmed from a kind of steam-driven explosion that scientists say are especially difficult to predict. Ontake had a minor eruption in 2007, but it’s first major recorded eruption was in 1979. Japan is considered by seismologists to be a hotbed of seismic activity. Read more here.
Each year, over 2.5 million children die worldwide because they do not receive life-saving vaccinations. To combat this global issue, researchers at Michigan State University are currently developing a fingerprint-based recognition system that has the potential to save babies’ lives through vaccination tracking. Vaccinations are normally tracked by paper documentation. However, keeping track of babies’ vaccinations on paper is highly ineffective in developing countries because they are easily lost or destroyed. Researchers are hoping that, over time, the new electronic registry systems will fix the issues of lacking and lost patient information in third world countries. Read more here.
Water is crucial for sustaining biological life. Consequently, scientists believe that finding the original source of Earth’s water is crucial for understanding how life-fostering environments are created, as well as estimating the likelihood of finding other environments that have the potential to hold life. Scientists at the Carnegie Institution now believe that the water found on Earth is older than the Sun, and originated in interstellar space. Read more here.
Harry Potter fans likely dream of owning an Invisibility Cloak. They may be excited to learn, then, that researchers at the University of Rochester, in New York, have discovered innovative new ways to use complex lenses to hide objects from view, in a process called cloaking. The so-called “Rochester Cloak” is realistically not cloak-like at all. Nonetheless, the cloaking device has been able to successfully make a hand, face, and a ruler disappear from view. Earlier versions of cloaking devices have been complicated and financially unfeasible. This new device breaks the mold, costing researchers little more than $1,000 in materials. The implications for these types of devices are broad, and researchers believe that they can be applied everywhere, from health care to the military. Read more here.
