● As an invader, the Hodgson mosquitofish will gnaw the tails of freshwater fish and tadpoles and eat the eggs of other fish and amphibians, causing the death of local animals. In a study recently published in Cross Science, researchers designed a robot fish to scare away Hodgson mosquitofish, revealing how fear changes their behavior, physiology and reproductive ability, which may help reverse the spread of invasive species.

●The World Health Organization recently reported that 89 countries and regions around the world have reported cases of infection with the new coronavirus variant Omicron; in areas where community transmission cases have occurred, the virus has spread at a rate of "doubling the number of cases within one and a half to three days." The WHO said that Omicron is spreading rapidly in countries and regions with a high proportion of the population fully vaccinated, but it is unclear whether this strain has a stronger ability to escape immunity or is more contagious, or both.
