A new international nature fund set up under the Global Environment Facility aims to help developing countries meet the biodiversity targets agreed at the COP15 summit in Montreal. The fund’s creation was one of the most-contentious issues at those talks, prompting walkouts and repeated negotiations between wealthy and poorer nations. So far, only Canada and the United Kingdom have pledged money, leaving roughly $40 million still needed to capitalise the fund ahead of COP16 next year.

Linguists have long thought that social context shapes grammar: communities with many non-native speakers, like trade hubs, were believed to favor simpler, easier-to-learn systems, while isolated, homogenous groups develop dense, specialized grammatical rules. A new study compiled measurements across about 1,300 languages to test whether languages used mainly by “societies of strangers” indeed show reduced grammatical complexity compared with languages used in more stable, insider communities.

Google is expanding a tool called "Results about you," first introduced last year to help people remove personal information from Search results. The new version will actively scan the public web for instances of a user’s personal data and send alerts so they can request removal. Google says the feature is currently available in the United States in English and will be rolled out to more regions over time.

Researchers report that reef-dwelling hogfish have light-sensitive cells embedded in their skin, allowing the animals to sense brightness and adjust their colour without relying solely on eyes. The study, published in Nature, shows this skin-based photoreception can continue to influence colour change even after death. Hogfish live in Atlantic reefs and can shift hues in milliseconds. Those rapid changes aid camouflage, social signalling and may help with temperature regulation and attracting mates.
