The remote Caribbean island of Redonda, part of Antigua and Barbuda, is home to numerous species of plants and animals found nowhere else on earth.

According to the government, introduced species kill 25m native New Zealand birds a year including the iconic ground-dwelling, flightless Kiwi, which die at a rate of 20 a week, and now number fewe

Researchers have identified key genes behind the infectivity of a virus that causes hand, foot, and mouth disease. Humans are the only known mammalian host, but in 2014, strains were bred that were capable of infecting mice and primate cell lines. These strains had mutant versions of the virus coat proteins. In this study, the same research group, led by Kaw Bing Chua and Vincent Chow at the National University of Singapore, introduced the mutations into the non-infectious strain individually and in combinations.

Australian researchers say rising sea levels have wiped out a rodent that lived on a tiny outcrop in the Great Barrier Reef, in what they say is the first documented extinction of a mammal species

Exclusive: scientists find no trace of the Bramble Cay melomys, a small rodent that was the only mammal endemic to Great Barrier Reef

Three studies investigate the bacteria in the guts of malnourished children and find that, when this microbiota is transferred into mice, supplements of certain microbes or sugars from human breast milk can restore normal growth.

Cutting down trees in rainforests facilitates the spread of invasive black rats, a study suggests.

The quality of diets in rodent feeding trials is crucial. We describe the contamination with environmental pollutants of 13 laboratory rodent diets from 5 continents. Measurements were performed using accredited methodologies. All diets were contaminated with pesticides (1-6 out of 262 measured), heavy metals (2-3 out of 4, mostly lead and cadmium), PCDD/Fs (1-13 out of 17) and PCBs (5-15 out of 18). Out of 22 GMOs tested for, Rounduptolerant GMOs were the most frequently detected, constituting up to 48% of the diet.

The increasing frequency of zoonotic disease events underscores a need to develop forecasting tools toward a more preemptive approach to outbreak investigation. We apply machine learning to data describing the traits and zoonotic pathogen diversity of the most speciose group of mammals, the rodents, which also comprise a disproportionate number of zoonotic disease reservoirs.

The researchers analyzed eight H10N8 viruses isolated from ducks and chickens in live poultry markets from 2009 to 2013 in China. These viruses showed distinct genetic diversity and formed five genotypes: the four duck isolates formed four different genotypes, whereas the four chicken viruses belong to a single genotype. The viruses bound to both human- and avian-type receptors, and four of the viruses caused 12.7% to 22.5% body weight loss in mice.
