Research finds companies that self-regulate to curb harmful practices increase profits
Credit: Unsplash/CC0 Public Domain Chinese companies that self-regulate to reduce harmful social practices are more likely to attract reputation-conscious buyers and increase exports to the Western world, a new Cornell University study finds. Activism in recent decades has led many companies and sectors to develop codes of conduct, certification schemes, and other types of self-regulation to control harmful environmental and…

Research results show that chimpanzees use tools to enhance competition
A new study published in the journal Science shows that chimpanzees have steadily honed their tool-using skills, a process that has unfolded over thousands of years through the exchange of ideas through migration between populations. “Planet of the Apes” may have been on to something. Chimpanzees have steadily honed their tool-using skills, a process that has unfolded over thousands of…

Marine research provides evidence of ‘Atlanticization’ of the Arctic Ocean
Members of the research team will collect samples. Credit: ICTA-UAB The international BIOCAL expedition, led by the Institute of Environmental Science and Technology of the Autonomous University of Barcelona (ICTA-UAB), has provided new evidence of the phenomenon of the “Atlanticization” of the Arctic Ocean. Gradual invasion of the polar Arctic Ocean from the Atlantic Ocean. The campaign collected samples to…

Collaborative research elucidates the mechanism of African plants that have anti-HIV effects
Chemical structure of the components of Croton megalobotrys Müll Arg (Namushen-1 and Namushen-2). Similarity to the reference protein kinase C activator Prostratin is shown. The substructure of protein kinase C activator/modulator (prostratin) is highlighted with the chemical structure of the phorbol ester from mukungul.

Award-winning dataset helps in seismic liquefaction research
Computer simulations are helping scientists and engineers improve liquefaction predictions. Liquefaction is an effect of earthquakes that causes soil to lose its rigidity and cause buildings to collapse, sometimes fatally. The dataset, which provides critical input for assessing seismic liquefaction induction, was awarded the 2024 DesignSafe Dataset Award in recognition of the dataset’s diverse contributions to natural hazard research.

Research reveals earliest evidence that humans used fire to shape Tasmania’s landscape
Emerald Swamp, Three Hammock Island. Credit: Simon Haberle Some of the first humans to arrive in Tasmania more than 41,000 years ago used fire to shape and manage the landscape, some 2,000 years earlier than previously thought. A British-Australian research team analyzed charcoal and pollen in ancient mud to uncover how Tasmanian indigenous people shaped their surroundings. This is the…

European marine research community calls for increased monitoring to improve ocean observations
Credit: Pixabay/CC0 Public Domain European ocean researchers are calling for urgent improvements and standardization of ocean monitoring. This call also extends to the international community, which gathers in Baku from today (11 November) for the United Nations Climate Change Conference, COP29. To protect the ocean as a partner in the fight against climate change, comprehensive monitoring of its condition is…

New research reveals deep-sea clues that solve the mysteries of the ice age 1 million years ago
Researchers analyzed sediment core samples collected by D/V JOIDES Resolution near Cape Town, South Africa. Their discoveries reveal details about changes in temperature and salinity in the deep ocean, as well as the history of mixing of water originating from both the Northern and Southern Hemispheres.
