Global plan outlines steps to monitor and reduce marine litter worldwide‎

Marine litter is a serious environmental problem worldwide. Reducing it would require implementing a global monitoring system, agreeing on the use of common methods and protocols for data collection, and categorizing all components of marine debris. This involves a tremendous scientific, political, and social effort at the international level—one that cannot be carried out with the same intensity by all countries—given the magnitude of what is still unknown about the pollution of seas and oceans, particularly the deep ocean, where the vast majority of marine litter accumulates.

First 'Bible map' published 500 years ago still influences how we think about borders, study suggests‎

The first Bible to feature a map of the Holy Land was published 500 years ago in 1525. The map was initially printed the wrong way round—showing the Mediterranean to the East—but its inclusion set a precedent which continues to shape our understanding of state borders today, a new Cambridge study argues.

Q&A: Calcium channel mechanism provides new insights into cellular quality control‎

When three bright minds from different disciplines come together, something exceptional can happen. This is exactly what Prof. Patricia Hidalgo, Dr. Beatrix Santiago-Schübel, and Dr. Mercedes Alfonso-Prieto achieved at Forschungszentrum Jülich. In an interdisciplinary project, they investigated how cells recognize and remove defective calcium channels—work that could prove significant not only for basic science, but also for future therapies for neurodegenerative diseases.

Bisexual individuals experience greater loneliness than homosexuals and heterosexuals, study suggests‎

According to an EHU study, lack of social support leads to increased loneliness of bisexual people. The work by Garikoitz Azkona of the Psychobiology group explored the relationship between sexual orientation and loneliness. It detected the highest level of loneliness among bisexual people, above that of homosexuals and heterosexuals.

New species of begonia found in Guangxi, China‎

The mega genus Begonia (Begoniaceae) is widely distributed in tropical and subtropical areas. It is one of the largest plant genera in the world with over 2,100 species. In China, the number of Begonia species has increased to 304 (including subspecies, varieties and natural hybrid species) in recent years.

A taste of the sea: Comparing five edible seaweeds‎

Researchers at the Leibniz Center for Tropical Marine Research (ZMT) and the University of Bremen have studied the nutritional value of five edible seaweed species, including some lesser-known algae, and examined their potential for sustainable nutrition. The study, published in the journal Discover Food, shows that the analyzed species are rich in polyunsaturated fatty acids and have strong antioxidant properties as well as high protein and mineral contents.

Local space weather impacts on technology and safety vary more than expected‎

A strong geomagnetic storm in spring 2024 brought the northern lights unusually far south, as the auroral oval expanded well beyond its typical position. "I am surprised at how sparse the measurement network is, even though we know that the impacts of space weather can vary greatly from one area to another," says Doctoral Researcher Otto Kärhä from the University of Oulu, Finland.

Dark matter-dark energy interaction shapes cosmic halo spin and alignment, simulations show‎

A cosmological simulation study by researchers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has systematically revealed, for the first time, how the interaction between dark matter and dark energy significantly influences the rotation and shape alignment of dark matter halos in the universe.

Caribbean rainfall driven by shifting long-term patterns in the Atlantic high-pressure system, study finds‎

A new study published in Science Advances overturns a long-standing paradigm in climate science that stronger Northern Hemisphere summer insolation produces stronger tropical rainfall. Instead, a precisely dated 129,000-year rainfall reconstruction from a Cuban cave shows that the Caribbean often did the opposite, drying during intervals of intensified summer insolation.
