The presence of humans is causing more animal populations -- including coyotes, elephants and tigers -- to become more nocturnal to avoid interaction with people, a recent study found. Researchers reviewed data from 76 studies of 62 species around the globe.
An implant that generates insulin when prompted by caffeine consumption might help free people with type 1 diabetes from insulin shots, a study suggests. The study is one of several published recently related to the health benefits of drinking coffee.
Even small amounts of drugs that make their way into bodies of water can have harmful effects on wildlife. A study published in Science of the Total Environment found that eels swimming in water containing small amounts of cocaine suffered hyperactivity and muscle damage, which could hamper their migration ability.
DNA tests have found that the unusual wolf-like creature shot in Montana last month was, indeed, a gray wolf. The female animal's coloring and the size of her ears, legs, paws and teeth deviated from what's normally seen in gray wolves, prompting the investigation.
Light drinkers may be less likely to develop cancer than those who drink more heavily or don't drink alcohol at all, according to a study published in PLOS Medicine.

A total of $40 million will be awarded by the Energy Department to 31 projects furthering studies on how organisms such as yeast, fungi, cyanobacteria and rare thermophilic microbes can be used to produce bioproducts including biofuels from renewable resources.
Seventy middle- and high-school students in an Ohio district participated in a weeklong career exploration event. The event was intended to introduce students to various career fields, including engineering.
Nonprofit Global Fishing Watch is using a new imaging system that allows it to monitor vessels that are fishing at night without transmitting location signals. The organization is also monitoring open ocean transshipment -- the act of one vessel transferring goods to another.
Engineering projects can be integrated into any subject and can reinvigorate instruction, writes Liza Rickey, a science, technology, engineering and math curriculum specialist. In this blog post, Rickey describes how to design engineering lessons and shares resources and ideas for lessons for all grade levels.
High-school students who are taught a subject such as math by teachers who either majored or minored in the same subject are more likely to graduate from college, according to a study of 6,000 students and their teachers across the country by a researcher at the University of Missouri.
