The Case of the Buffalo and the Frog

Kermit the Frog’s saying, “With good friends, you can’t lose,” appears to apply—rather unusually—to the marsh frog and the Anatolian water buffalo of northern Turkey.

Undersea Light Deception

​In order to survive, many animals have undergone some incredibly unique adaptations. The ability to change colors is fairly common in the animal world, as is the development of dazzling or dull colors for camouflage. But a rare few critters use light itself to deceive or even not to be seen at all. In the dark depths of the oceans, the smallest traces of light can illuminate a hungry fish’s potential dinner. For the hunted, then, it is better not to reflect light at all, and become nearly invisible, or to create or bend light so as to appear as something else.

Questioning Herbicide Safety

​In June 2017, the state of California classified glyphosate, the most widely used herbicidal chemical in the world, as a known carcinogen(cancer-causing substance). In the early 1970’s, organic chemist John E. Franz discovered the plant-killing chemical compound while working for the Monsanto Company, a leading chemical maker in the United States.

Australia’s Ancient Origins

New excavations conducted at Madjedbebe, a rock shelter in northern Australia, have provided evidence that humans first arrived there around 65,000 years ago. That date, based on sophisticated modern dating methods, pushes back the earliest physical evidence for human occupation in Australia by at least 15,000 years. The discovery is forcing scientists to reevaluate some common theories about the ancestors of today’s Aboriginal people of Australia.

Naledi of the Rising Star

​Recent studies show that Homo naledi, an intriguing species of prehistoric humans, may have lived far more recently than previously believed.

A New Twist on the Naked Mole-Rat

Naked mole-rats may not rank highly on the cute scale, but they are certainly one of the world’s most bizarre and uniquely adapted animals.

However, naked mole-rats belong to a special group of cold-blooded mammals (along with the platypus and other rare oddities).

Hot Water in Icy Space

​Enceladus, an icy moon orbiting Saturn, is quickly becoming one of the hottest spots in the search for life beyond Earth. A group of scientists led by J. Hunter Waite of the Southwestern Research Institute in San Antonio, Texas, has determined that hydrothermal vents (flows of heated water) likely exist in a global ocean beneath Enceladus’s icy crust. These vents could possibly be home to life forms. Waite and his team published their findings last month in the journal Science.

A Unique Martian Potato

Human exploration of Mars is one of the primary long-term goals of such space agencies as the United States National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA). But before people get there, scientists must solve a host of problems. First among them will be how to feed astronauts during an extended stay in the harsh environment of the Red Planet.

A Canadian River’s Sudden End

In Canada’s Yukon territory, increased melting of the vast Kaskawulsh Glacier has caused the nearby Slims River to run dry. The Slims, once a gushing channel of glacial melt water, is now a waterless expanse of mud and dust.

Shaking the Dino Family Tree

For decades, dinosaurs have been grouped into two broad categories: long-necked sauropods and meat-eating theropods (along with birds) in one group, and the remaining plant-eaters, such as Stegosaurus, Triceratops, and Iguanodon, in the other. In March, a group led by Matthew G. Baron from the University of Cambridge in the United Kingdom challenged that view. They published their findings in the prestigious scientific journal Nature.
