Chemicals linked to endocrine disorder in older pet cats

New research suggests that there may be a link between higher levels of per- and polyfluoroalkyl substances (PFAS) in the environment and higher levels of hyperthyroidism in pet cats as they age. The findings are published in Environmental Toxicology and Chemistry.

PFAS are a family of more than 3,000 structures of highly fluorinated chemicals used in...

Why do we love bees but hate wasps?

A lack of understanding of the important role of wasps in the ecosystem and economy is a fundamental reason why they are universally despised whereas bees are much loved, according to UCL-led research.

How birds can stay slim, even when they overeat

Noticing that songbirds, such as finches, never seem to get fat despite overeating at bird feeders, London environmental biologist Lewis Halsey wondered whether the amount of energy birds put into singing, fidgeting, or exercising could be adjusted in ways that regulate weight. In a literature review published September 18 in the journal Trends in Ecology...
