Second infections raise questions about long-term immunity to COVID-19 and the prospects for a vaccine.

In rodents with type 2 diabetes, a single surgical injection of a protein called fibroblast growth factor 1 can restore blood sugar levels to normal for weeks or months. Yet how this growth factor acts in the brain to generate this lasting benefit has been poorly understood.

team of scientists from ASU and Shanghai Jiao Tong University (SJTU) led by Hao Yan, ASU's Milton Glick Professor in the School of Molecular Sciences, and director of the ASU Biodesign Institute's Center for Molecular Design and Biomimetics, has just announced the creation of a new type of meta-DNA structures that will open up the fields of optoelectronics (including information storage and encryption) as well as synthetic biology.

A fifth of carbon dioxide emissions come from multinational companies' global supply chains, according to a new study led by UCL and Tianjin University that shows the scope of multinationals' influence on climate change.

The partial skull of an armoured fish that swam in the oceans over 400m years ago could turn the evolutionary history of sharks on its head, researchers have said.

study reveals the Pac-Man-like strategies adopted by different cell types when making long journeys through an organism

How did life originate? Scientists have been studying the question for decades, and they've developed ingenious methods to try to find out. They've even enlisted biology's most powerful theory, Darwinian evolution, in the search. But they still don't have a complete answer. What they have hit is the world's most theoretically fertile dead end. When scientists look for life's origins, they usually work in one of two directions. They work backwards in time through the record of organisms that have lived on Earth, or they work forward from one of the many hypothetical prebiotic worlds in which life could have emerged.

The collapse of China's prosperous Ming dynasty, one of the most stable in Chinese history, has been attributed, in part, to the 1641 eruption of a volcano thousands of kilometres from the imperial capital in Beijing.

Covid-19 has heightened our perception of danger so that every day is a series of finely balanced calculations. How do we decide which are the risks worth taking, asks Sarah Perry

A team of researchers from the U.K., China, and Italy has found evidence that suggests oxygen depletion in the world's oceans led to the end-Triassic mass extinction. In their paper published in the journal Science Advances, the group describes their study of ancient rocks found in multiple locations around the world.

New geologic findings about the makeup of the Earth's mantle are helping scientists better understand long-term climate stability and even how seismic waves move through the planet's layers.

In this Review, we outline the history and evolution of the burning embers and associated reasons for concern framework, focusing on the methodological approaches and advances. While the assessment framework and figure design have been broadly retained over time, refinements in methodology have occurred, including the consideration of different risks, use of confidence statements, more formalized protocols and standardized metrics. Comparison across reports reveals that the risk level at a given temperature has generally increased with each assessment cycle, reflecting accumulating scientific evidence. For future assessments, an explicit, transparent and systematic process of expert elicitation is needed to enhance comparability, quality and credibility of burning embers.
