Six New Species

All six species are smaller than a British 1p coin — around 15mm long — when fully grown. Adult males of the tiniest of these species, named Craugastor candelariensis, grow to only 13mm.   The newly discovered species are known as ‘direct-developing’ frogs: rather than hatching from eggs into tadpoles like most frogs, they emerge …

Pathogens Hitch a Ride

The study, published April 26 in the journal Scientific Reports, is the first to connect microplastics in the ocean with land-based pathogens. It found that microplastics can make it easier for disease-causing pathogens to concentrate in plastic-contaminated areas of the ocean.   The pathogens studied — Toxoplasma gondii, Cryptosporidium (Crypto) and Giardia — can infect …

Male Spiders

“We found that mating was always ended by a catapulting, which is so fast that common cameras could not record the details clearly,” says Shichang Zhang of Hubei University in Wuhan, China.   The reason the males catapult themselves is simple: to avoid being eaten by the female in an act of sexual cannibalism. The …

Water Processing

Wherever people are living, hormones used in e.g. contraceptives or agriculture enter the wastewater. Steroid hormones, such as sex hormones and corticosteroids, may accumulate in the environment.   Inspired by Solar Cell Technology For years, Schäfer has studied water processing by nanofiltration. For this purpose, she uses polymer membranes with nanometer-sized pores. However, nanofiltration requires …
