Monkeys and other animals communicate through calls that can differ depending on region. The common marmoset is one such animal that communicates using regional dialects. Researchers have now found out that they even adapt their dialect when they move to a different area.
Read moreTo test the possible relationship between the gut and chemo brain, a lab is examining chemo's effects on mice whose guts have been manipulated before treatment. One experiment involves feeding the mice antibiotics. The other relies on the universal practice among mice of eating their own and their roommates' feces.
Read moreWhether they occur on holiday routes or the daily commute, traffic jams affect cars as well as pedestrians. Scientists have demonstrated that ant colonies, however, are spared these problems and circulate easily, even in the event of extremely dense traffic, thus ensuring consistent efficiency in their foraging.
Read moreScientists working to identify coral reef organisms analyzed more than 4.7 million animal DNA sequences from GenBank, the most commonly used tool used to identify environmental DNA, and discovered that animal identification errors are surprisingly rare — but sometimes very funny.
Read moreThe first study of a toad mimicking a venomous snake reveals that it likely imitates one of Africa's largest vipers in both appearance and behavior.
Read moreBiologists have described a new species of praying mantis that displays the first documented example of conspicuous mimicking of a wasp among praying mantises.
Read morePulmonary hypertension is a type of high blood pressure that affects the lungs of both animals and people. When tiny vessels in the lungs become narrowed or blocked, it becomes harder for blood to flow through and can cause the heart to weaken or fail.
Read moreA study has now found that a type of opsin known as neuropsin is expressed in the hair follicles of mice and synchronize the skin's circadian clock to the light-dark cycle, independent of the eyes or brain. Researchers now want to see if skin heals better if it's exposed to certain types of light.
Read moreRising night-time temperatures are causing woodland birds to build nests and lay eggs earlier in springtime, research shows.
Read moreNative to South America, imported fire ants have now spread to parts of North America and elsewhere around the world. These invasive pests have painful stings that, in some cases, can cause serious medical problems, such as hypersensitivity reactions, infections and even kidney failure. Now, researchers have identified pyridine alkaloids that, along with other venom components, could contribute to these conditions.
