Modern fluorescence microscopy can generate images of living cells as stunning to look at as they are informative to study. For techniques like fluorescence lifetime imaging microscopy (FLIM), those images provide a window into cell metabolism, helping scientists study cancer
People communicate with each other, sometimes face to face, sometimes with a text message or phone call. Cells also communicate with each other, sometimes by touching and sometimes by sending signals across space and time. But while texts and phone calls can be traced to figure

Researchers have repurposed an AI model designed for visual identification tasks to detect Bryde's whale calls contained within seismic data collected in the South China Sea. The detection system precisely identified calls more than 96% of the time and even identified some call
Most people think they are open-minded and would like others to perceive them as such. But for the things that matter most—religious beliefs, for example, or the meaning of life—few of us are genuinely willing to consider that we might be wrong, let alone do the hard work of
Ice-age sea-level declines may have turned seafloor volcanoes into natural iron fertilizer for plankton, potentially enhancing ocean carbon storage, Boston College researchers report in the journal Nature Geoscience.

The quest to identify a new way to potentially counter one of the world's most widely discussed solar geoengineering proposals has taken a new, exciting turn—raising questions about how future climate interventions could be governed.
Conventional cancer treatments, such as chemotherapy, often lack specificity and can damage both cancerous and healthy cells, leading to severe side effects. With this in mind, researchers at Indian Institute of Technology Gandhinagar (IITGN) have developed DNA nanostructures
Researchers have uncovered new insights into how phosphorus from recycled materials moves through soil—offering guidance to support more sustainable fertilizer use. Phosphorus is an essential nutrient for plant growth, yet many soils lack enough of it to support strong crop
Human-caused sea-level rise has significantly increased the frequency of extreme coastal flooding worldwide, according to a new study led by a Tulane University researcher. The research, published in the journal Nature Climate Change, found that coastal flooding events expected
Trees, grasses, corals, and oysters are foundational to the structure of an ecosystem while they are alive. But new research led by the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder shows that when they die—due to
A new telescope technology—measuring just 6 millimeters (0.24 inches) in diameter—could improve how future space missions study and monitor the sun while simplifying onboard hardware and reducing costs.
Eight years after a Chinese scientist's report of gene-edited babies shocked the world, U.S. scientists reported editing embryos not meant for pregnancies using a more precise technique
Te Whare Wānanga o Waitaha | University of Canterbury (UC) School of Biological Sciences researcher Dr. Ben Crichton has studied kōkopu—whitebait species that can live for 10 years or more. Whitebait is the collective term for the juveniles of six species of freshwater fish.
Financial markets are blind to the economic costs of biodiversity loss, leaving several countries at risk of defaulting on debt, according to new research published in Nature. While environmental degradation is recognized as a serious financial risk, sovereign debt markets
It is generally accepted by archaeologists that modern humans originated in Africa and dispersed worldwide, while other hominins went extinct. Yet how and when Homo sapiens dispersed out of Africa, and whether it was an abrupt event, is still debated. Even more uncertain is how
There's a question at the heart of SETI that doesn't get nearly enough attention. It isn't whether aliens exist, and it isn't whether we have the technology to detect them. It's a far more practical problem: With a billion stars in our galaxy and finite telescope time, how do
We're used to a lot of different natural things falling out of the sky. These can include snow, rain and sometimes even frogs (yes, really). All of these relate to weather phenomena.
A massive underground detector aimed at understanding the mysterious ghost particles in our universe released its first major results on Wednesday.
In early June, an ABC Four Corners investigation into NSW Police showcased firsthand accounts of police using excessive force against the public.
When kids watch cartoons, they're absorbing much more than a plot. Thanks to the use of foreign accents in shows, they're also learning a shorthand for moral character, new research from the University of Toronto Mississauga suggests.
