New species discovered: Protist parasites contribute to the stability of rainforest ecosystems

Tue, 21/03/2017 - 4:38pm
Tropical rainforests are one of the most species-rich areas on earth. Thousands of animal and plant species live there. The smaller microbial protists, which are not visible to the naked eye, are also native to these forests, where they live in the soils and elsewhere. A team of researchers has examined them more closely by analyzing their DNA. They discovered many unknown species, including many parasites, which may contribute to the stability of rainforest ecosystems.

Having a laugh with recruitment

Tue, 21/03/2017 - 4:36pm
Can humour on social media help managers find the most appropriate candidates for the job vacancies they hope to fill? Researchers suggest that humorous recruitment campaigns can increase exposure for a given job ad but conversely the approach might lead to flippant applications at which point it might be difficult to separate the serious candidate from an inappropriate one. The team also suggests that choosing a particular social media channel over another may skew the type of applicants they receive for a given job, for better or worse.

Dead zones may threaten coral reefs worldwide

Tue, 21/03/2017 - 4:25pm
Dead zones affect dozens of coral reefs around the world and threaten hundreds more according to a new study. Watching a massive coral reef die-off on the Caribbean coast of Panama, they suspected it was caused by a dead zone -- a low-oxygen area that snuffs out marine life -- rather than by ocean warming or acidification.

Testing the efficacy of new gene therapies more efficiently

Tue, 21/03/2017 - 3:03pm
Using a new cellular model, innovative gene therapy approaches for the hereditary immunodeficiency Chronic Granulomatous Disease can be tested faster and cost-effectively in the lab for their efficacy. A team of researchers has successfully achieved this using the 'gene-scissor' CRISPR/Cas9 technology. The aim is to treat severely affected patients in the near future using novel approaches.
