Advanced communication? Spider monkeys adjust their “whinnies” to regain contact with their group
At least one species of monkey seems to understand that low-frequency sounds travel much further than high-pitched ones. Whenever a Geoffroy’s spider monkey (Ateles geoffroyi) gets separated from its group, the animal deliberately reduces the pitch of its calls. By lowering the frequency of its voice, the isolated monkey makes itself heard over greater distances. […]

Hiding in plain sight: Peacocks’ brightly colored feathers could be camouflage that hides them from predators, suggests study
The words “peacock” and “camouflage” are generally considered opposites. But Pennsylvania-based researchers now argue that the vivid colors of the flightless bird conceal it from predatory mammals. To the human eye, the tail feathers of the male peacock stand out like a visual sore thumb. However, it so happens that the retina of the human […]

Due to extreme pollution of the world’s oceans, sea anemones are now eating microplastics
Vertebrates are not the only marine organisms that accidentally gulp down mouthfuls of the growing number of microplastics in the ocean. Invertebrates like corals and sea anemones also ingest tiny pieces of plastic that they have mistaken for their prey. In a study supported by the Carnegie Institution for Science (Carnegie), researchers learned that sea anemones […]

Oxygen loss in ancient oceans led to mass extinctions – will history repeat itself?
The ongoing drop in ocean oxygen levels is not a new thing. Researchers warn that a similar loss of life-giving gas in the ancient oceans may have triggered a mass extinction in marine life more than 430 million years ago. The Ireviken extinction event took place during the Silurian Period of Earth. It killed off […]

“Tree kill zone” in Yellowstone National Park hints at new magma activity below the surface
The massive amounts of magma slumbering beneath Yellowstone National Park stir anew. Researchers reported the appearance of a new thermal area in the park that killed off the plants in its vicinity. The area measured eight acres (3.2 hectares), enough to fit four soccer fields. It first appeared on infrared images taken by Landsat satellites […]

Want to build bee-friendly environments? Follow this science-based guide
Beekeepers are not the only ones who benefit from making bees more welcome in the garden or yard. By cultivating the appropriate types of flowering plants during each season, people will help support the populations of wild bees that live in urban and suburban areas. Both natural and agricultural ecosystems depend on the pollinating activities […]

Foreign landscape: Scientists find vibrant “living rocks,” mirror pools on ocean floor
At the bottom of Mexico’s Gulf of California lies hydrothermal vents and cold seeps with hydrocarbon-rich fluids. A recent scientific expedition to this alien environment uncovered the existence of massive venting mineral towers that teemed with strange organisms. The towers reached heights of 23 m and widths of 10 m. Their volcanic flanges heated the […]

Greener and cleaner: Can “green” roofs planted with vegetation minimize indoor air pollution?
Setting up a green roof on your home is a good way to protect its indoor air quality from ozone and other air pollutants coming from the outdoors. A recent study showed how even a partial green roof reduced the amount of ozone entering a commercial building. As the name implies, a green roof supports […]

Water cooler talk – Andean bears use water sources not only to drink, but also to communicate with others
The watering holes scattered throughout the Andes mountain range of Peru also serve as communication spots for Andean bears. A new study discovered that the bears left messages for each other on the plants near a source of water. Bears are known for their tree-rubbing behavior. They bite, claw, and rub parts of their bodies on shrubs and […]

Stripes make terrible landing strips: Flies bite zebras less because the contrast causes optical disruption, says a study
Theories abound as to why zebras sport distinctive black-and-white stripes on their hides. In a recent study, a team led by the University of California (UC), Davis claimed that the pattern confuses blood-sucking flies, causing the insects to miss their zebra-sized landing zone completely. The flies feed on the blood of zebras and other warm-blooded […]
