Entanglements of humpback whales in fish farms rare – and naivety could be to blame

The first study of humpback whale entanglements in B.C. aquaculture facilities in PLOS One found eight over 13 years, with the curiosity of young whales a potential contributing factor. A rare occurrence Entanglements are one of several threats to humpbacks. The eight occurred from 2008 to 2021 at seven fish farms, with five animals successfully released and three deaths. The entanglements accounted for less than six per cent of all entanglements in B.C. Approximately 7,000 animals return to B.C. waters annually. Most whales became entangled between the predator and containment nets on fish farms. In five cases, experienced ...

New geological study: Scandinavia was born in Greenland

In a Finnish outcrop nestled between some of Northern Europe's oldest mountains, researchers have found traces of a previously hidden part of Earth's crust that points more than three billion years back in time and north towards Greenland. These traces were found in the mineral zircon, which after chemical analyses, indicated to researchers from the Department of Geosciences and Natural Resource Management that the "foundation" upon which Denmark and Scandinavia rest, was probably 'born' from Greenland approximately 3.75 billion years ago. "Our data suggest that the oldest part of Earth's crust beneath Scandinavia originates ...

Research team identifies genetic contribution to the composition of the microbiome around maize roots

In order for plants to grow, they absorb water and nutrients through their roots. In doing so, they rely on tiny helpers: bacteria and fungi in particular are found in a thin layer around the roots. These microbes also ward off organisms that are harmful to the plant, just as the "microbiome" in the human gut helps determine whether we fall ill or stay healthy. An international research team led by the University of Bonn and with the participation of the IPK Leibniz Institute has now demonstrated on maize plants that the genetic make-up of the host plant has a significant influence on the composition of the root microbes. "It was shown ...

Say hello to biodegradable microplastics

Microplastics are tiny, nearly indestructible fragments shed from everyday plastic products. As we learn more about microplastics, the news keeps getting worse. Already well-documented in our oceans and soil, we’re now discovering them in the unlikeliest of places: our arteries, lungs and even placentas. Microplastics can take anywhere from 100 to 1,000 years to break down and, in the meantime, our planet and bodies are becoming more polluted with these materials every day. Finding viable alternatives to traditional petroleum-based plastics and microplastics has never been more important. New research from scientists ...

New method for analyzing nanoporous materials

In addition to their main components, the properties of crystalline and nanoporous materials often depend crucially on guest atoms or ions that are embedded in the tiny pores of their lattice structure. This applies to high-tech materials used in sensor or separation technology as well as to natural materials. The bluish gemstone aquamarine, for example, would be colourless without such guest components. Determining the type and position of guest components is difficult, as many materials react sensitively to the radiation emissions ...

An immunotherapy to overcome resistant leukemia

Acute myeloid leukemia (AML) is an aggressive form of blood cancer. It is caused by mutations in a large number of genes that are acquired in the course of a person’s life. One of these genes – the tumor suppressor gene TP53 – plays a key role. Normally, TP53 helps to prevent the development of tumors. Blood cancer patients in whom this gene is mutated, however, face an extremely poor prognosis, as their genes are resistant to conventional chemotherapeutic agents. Intensive research is therefore being carried out into new therapeutic approaches, ...
