Tapping the ocean as a source of natural products

New species and new molecules discovered

24-Jun-2022

Using DNA data, ETH researchers have examined seawater to find not only new species of bacteria, but also previously unknown natural products that may one day prove beneficial. The oceans are teeming with countless forms of life, from the world’s largest creature – the blue whale– to miniscule ...

Which animals exist right here? Now researchers are able to find the answer out of thin air

Researchers have found a way to collect samples of animal DNA from the air with a new method

10-Jan-2022

Identifying the animal species that live in a particular area can be a lot of work. Usually it means spotting the animals with the naked eye or recording them using a camera trap. Their presence can also be identified via the traces they leave on the ground or in the form of e.g. faeces. Common ...

DNA in archaeological sediments

Ancient human and animal DNA can remain stably localized in sediments, preserved in microscopic fragments of bone and feces

06-Jan-2022

The analysis of ancient DNA preserved in sediments is an emerging technology allowing for the detection of the past presence of humans and other animals at archaeological sites. Yet, little is known about how DNA is preserved in sediment for long periods of time. An international team of ...

Human environmental genome recovered in the absence of skeletal remains

Innovative approach permits the identification of DNA in samples of environmental material

14-Jul-2021

Ancient sediments from caves have already proven to preserve DNA for thousands of years. The amount of recovered sequences from environmental sediments, however, is generally low, which difficults the analyses to be performed with these sequences. A study led by Ron Pinhasi and Pere Gelabert of ...

Aviation safety: Rapid test for harmful microbes in kerosene developed

Faster and more robust than a PCR test

12-Apr-2021

Fuels such as kerosene or diesel can be contaminated by fungi or bacteria. The microorganisms settle in the liquid itself, on the inner walls of tanks and pipes or in fuel filters and feed on carbon atoms. Since the fungi and bacteria multiply well in this environment, they can form a streaky ...

New method: Y chromosomes of Neandertals and Denisovans now sequenced

Neandertals have adopted male sex chromosome from modern humans

28-Sep-2020

An international research team led by Martin Petr and Janet Kelso of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has determined Y chromosome sequences of three Neandertals and two Denisovans. These Y chromosomes provide new insights into the relationships and ...

Speeding up genetic diagnosis of Huntington’s disease

11-Jan-2019

Elongated segments of DNA cause Huntington’s disease and certain other disorders of the brain. Researchers funded by the SNSF have developed a method to determine the length of the mutated genes quickly and easily. People with Huntington’s disease suffer from jerky body movements and decreasing ...

A bucket full of genes: pond water reveals tropical frogs

30-Aug-2018

When a frog jumps into a pond, it inevitably leaves behind traces of its genetic material. Using water samples from the Bolivian lowlands, Senckenberg scientists were now able to demonstrate that the analysis of this so-called environmental DNA allows the reliable identification of the frog ...

From exposomics to phytotoxins: Safe foodstuffs in the focus of analytica 2018

21-Mar-2018

What substances occurring naturally in foodstuffs jeopardize our health? How do pollutants affect our genetic material? Is baking paper a cause for concern? Such questions from the food sciences will be in the focus of the leading trade fair analytica and the accompanying analytica conference, ...

Tracking microbial faecal pollution in water

Identifying faecal bacteria by their DNA

30-May-2017

In a project supported by the Austrian Science Fund FWF, the microbiologist Andreas Farnleitner is looking at new methods for analysing faecal pollution in water. Using DNA analytics, the scientist aims to develop comprehensive and simple methods to determine the extent and origin of faecal ...
