The Nature Microbiology journal reported that scientists at the German University of Tübingen have discovered a novel antibiotic substance from the human nose that can be used against pathogenic bacteria.

“Named epifadin, the molecule is produced from specific strains of the bacterial species Staphylococcus epidermidis, which occur on the mucous membrane of the inside wall of the nose,” the journal added.

Epifadin constitutes a new, previously unknown class of antimicrobial compounds that kills microorganisms and could be used as a lead structure for the development of novel antibiotics.

Epifadin not only works against the bacteria that are locally in competition with Staphylococcus epidermidis, it is also effective against bacteria from other habitats such as the intestine and certain fungi.

The researchers found that it is especially effective against the potential pathogens Staphylococcus aureus, a hospital-acquired infection which is particularly dangerous in antibiotic-resistant form (MRSA). But, more research is needed to discover whether epifadin or its derivates can be used for therapy.

An "amphibious mouse" with partially webbed feet that eats aquatic insects was among 27 new species discovered during a 2022 expedition to Peru's Amazon, according to Conservation International.

Scientists also discovered a spiny mouse, a squirrel, eight types of fish, three amphibians and 10 types of butterflies, Trond Larsen, head of Conservation International's Rapid Assessment Program, told Reuters this week.

He added that another 48 species found by investigators were potentially new, but needed further study.

The new species were found in Alto Mayo, a protected area with several ecosystems, Indigenous territories and villages.

"Discovering so many new species of mammals and vertebrates is really incredible, especially in such a human-influenced landscape as Alto Mayo," Larsen said.

The expedition between June and July 2022 was made up of 13 scientists plus local technicians and members of Indigenous groups.

"It was really fantastic to work so closely with the Awajun people. They have extensive traditional knowledge about the forests, animals and plants they live side-by-side with," Larsen said.

Among the new species, Larsen highlighted the spiny mouse that has stiff fur, the amphibious mouse, and a dwarf squirrel that measures 14 cm (5.5 in).

"(The squirrel) fits so easily in the palm of your hand. Adorable and beautiful chestnut-brown color, very fast," Larsen said. "It jumps quickly and hides in the trees."

Another favorite discovery was the blob-headed fish, a type of armored catfish, he said.

A total of 2,046 species were recorded during the 38-day expedition using camera traps, bioacoustic sensors and DNA sampling. Among them, 49 were classified as threatened, including the yellow-tailed woolly monkey and the tree monkey.

Larsen said the discoveries reinforced the need to protect the area.

"Unless steps are taken now to safeguard these sites and help restore parts of the landscape ... there's a strong chance they won't persist in the long term," Larsen said.
