Scientists develop rapid cell division in marine sponges

Vertebrate, insect, and plant cell lines are important tools for research in many disciplines, including human health, evolutionary and developmental biology, agriculture and toxicology. Cell lines have been established for many organisms, including freshwater and terrestrial invertebrates. Despite many efforts over multiple decades, there are still no cell lines for marine invertebrates including marine sponges,…

New research into badger dispersal could minimize bovine tuberculosis spread

Credit: CC0 Public Domain Zoology researchers from Trinity, working with the Department of Agriculture, Food and The Marine (DAFM) and the National Parks and Wildlife Service (NPWS), have unlocked the secrets of dispersing badgers. Their research, reported today, has major implications for implementing vaccination programs to limit the spread of bovine tuberculosis (TB). The findings…

Much of the giant kelp in the north…

Parasite manipulates algal metabolism for its own benefit

New ecology theory describes ‘frenemy’ networks

A new theory says social networking, even between competing species, plays a much bigger role in ecology than anyone previously thought. “There’s mounting evidence that different species pay attention to each other in the wild, especially if they share predators,” says Mike Gil, a postdoctoral researcher at the University of California, Davis who is currently…

More than 11,000 scientists declare global climate emergency in signed letter

An open letter signed by thousands of scientists from around the world may be the clearest demonstration yet of their near-unanimous agreement over the globe’s emerging climate crisis.Published Tuesday in the journal BioScience, the letter includes 11,258 signatures from 153 countries, including 409 from Canada.“We declare … clearly and unequivocally that planet Earth is facing a climate emergency,”…

Parasite manipulates algal metabolism for its own benefit

Microalgae can form massive assemblages in oceans, attracting many opportunistic organisms; these are capable of eliminating the entire algal population within a short time. However, the underlying mechanisms of this watery arms race are largely unknown. In a new publication in Nature Communications, researchers from the Max Planck Institute for Chemical Ecology and the universities…

China’s ocean waste surges 27% in 2018: ministry

BEIJING/SHANGHAI (Reuters) – China dumped a total of 200.7 million cubic meters of waste into its coastal waters in 2018, a 27% rise on the previous year and the highest level in at least a decade, the country’s environment ministry said on Tuesday.
