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 […]

People are now refraining from using plastic that contains bisphenol A (BPA). However, they may still get exposed to the toxic substance by drinking it from a coffee maker with BPA-laced plastic parts. BPA is an industrial chemical found in plastic products like food storage containers and water bottles. Researchers warn that the substance causes diseases […]

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 […]

If Mars has methane, does it mean there’s life on the red planet?
A recent study by European researchers strengthened the case for seasonal spikes of methane in Mars. First discovered by NASA’s Curiosity rover in 2013, the latest methane spikes were confirmed by orbiting spacecraft. In 2019, Curiosity discovered that the methane levels in the Martian atmosphere changed from season to season. The gas hit its peak during the […]

“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 […]

Scientists develop liquid that changes color with heat
Thermochromic materials are “smart” materials that change their color depending on the temperature of their surroundings. Recently, a Singaporean research team presented a liquid that grew much darker as it got hotter. Their invention might prove useful in smart windows and other applications that respond to temperature changes. Unlike earlier examples that relied on dyes […]

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 […]

Deadly blow to the chest does not affect heart contraction, according to research
Why do healthy baseball players die when a ball slams into their chest while patients survive potentially lethal tachyarrhythmia attacks when they get a timely thump to the chest? Swiss researchers hoped to answer this puzzle with a recently-developed instrument that simulates how a blow to the chest affects the heart rate. When the chest receives […]

Why does coral have creatures that make chlorophyll but don’t photosynthesize?
What do you call a tiny critter that lives in most corals and creates chlorophyll but doesn’t bother using it to turn sunlight into energy? Dubbed corallicolid, this unusual creature is the first known organism that is capable of phototropic behavior yet doesn’t perform photosynthesis. Corallicolids belong to the phylum Apicomplexa. Its relatives include the […]
