700,000 years ahead of their teeth: The carbs that made us human

As early humans spread from lush African forests into grasslands, their need for ready sources of energy led them to develop a taste for grassy plants, especially grains and the starchy plant tissue hidden underground. But a new Dartmouth-led study shows that hominins began feasting on these carbohydrate-rich foods before they had the ideal teeth […]

Dental Stem Cells Differentiate on Biodentine Nanofibers

In a groundbreaking advance within the field of regenerative medicine, researchers have unveiled a novel approach to enhance dental and bone tissue engineering by leveraging the unique properties of dental pulp stem cells (DPSCs) cultured on specially designed polymer nanofibers. The study, recently published in BioMedical Engineering OnLine, explores the odontogenic and osteogenic potential of […]

Can Tariffs Lead to a More Circular Economy? – State of the Planet

As global trade tensions mount and countries recalibrate their economic priorities, tariffs may have the ability to play an unexpected role in the sustainability conversation. Tariffs on imports, while often viewed as controversial and protectionist weapons, could paradoxically drive the shift not only toward less production, but also toward more localized, circular and environmentally conscious […]

How AI is supercharging plant immunity to fight deadly bacteria

Scientists at the University of California, Davis, used artificial intelligence to help plants recognize a wider range of bacterial threats — which may lead to new ways to protect crops like tomatoes and potatoes from devastating diseases. The study was published in Nature Plants. Plants, like animals, have immune systems. Part of their defense toolkit […]

Koalas on the brink: Precision DNA test offers a lifeline to Australia’s icons

A University of Queensland-led project has developed a tool to standardize genetic testing of koala populations, providing a significant boost to conservation and recovery efforts. Dr Lyndal Hulse from UQ’s School of the Environment said the standardized koala genetic marker panel provides a consistent method for researchers nationwide to capture and share koala genetic variation, […]

AI-directed voxel extraction and volume EM identify intrusions as sites of mitochondrial contact

Membrane contact sites (MCSs) establish organelle interactomes in cells to enable communication and exchange of materials. Volume EM (vEM) is ideally suited for MCS analyses, but semantic segmentation of large vEM datasets remains challenging. Recent adoption of artificial intelligence (AI) for segmentation has greatly enhanced our analysis capabilities. However, we show that organelle boundaries, which […]

Plastics production ‘a global threat’

More than 60 leading scientists from around the world have issued an urgent call for governments to agree on ambitious, enforceable action to tackle plastic pollution, as the final round of UN negotiations on a global plastics treaty approaches. The letters, published today in Cambridge University Press journal Cambridge Prisms: Plastics in the run-up to the […]

Merbecovirus S2 Vaccines Trigger Cross-Reactive MERS Protection

In a groundbreaking study recently published in npj Viruses, a team of researchers led by Halfmann and colleagues has unveiled promising new insights into vaccine design against Merbecoviruses, a subgenus of coronaviruses that includes the Middle East Respiratory Syndrome coronavirus (MERS-CoV). Their work focuses on the S2 subunit of the spike (S) glycoprotein, a component […]
