The Dark Energy Spectroscopic Instrument used millions of galaxies and quasars to build the largest 3D map of our universe to date. Combining their data with other experiments shows signs that the impact of dark energy may be weakening over time -- and the standard model of how the universe works may need an update. Read more ›

A research team has achieved a new milestone in 3D X-ray imaging technology. The scientists have captured high-resolution CT scans of the interior of a large, dense object -- a gas turbine blade -- using a compact, laser-driven X-ray source. The work is part of a larger vision to leverage high-intensity lasers for a wide range of uses, from studying inertial fusion energy to generating bright beams of GeV electrons... Read more ›

Nearly 3 out of every 4 older Americans have experienced at least one extreme weather event in the last two years, a poll finds. And living through such an event appears to make a big difference in how they view the potential impact of climate change on their health. People over 50 who recently experienced an extreme weather event are far more likely to express concern about the effects of... Read more ›

Mammograms, with the help of artificial intelligence (AI) models, may reveal much more than cancer, according to a new study. The findings highlight how these important cancer screening tools can also be used to assess the amount of calcium buildup in the arteries within breast tissue -- an indicator of cardiovascular health.

Advances in the gene-editing technology known as CRISPR-Cas9 over the past 15 years have yielded important new insights into the roles that specific genes play in many diseases. But to date this technology -- which allows scientists to use a 'guide' RNA to modify DNA sequences and evaluate the effects -- is able to target, delete, replace, or modify only single gene sequences with a single guide RNA and has...

Our skin and mucous membranes are protected by epithelial cells. This 'barrier' tissue performs its function thanks to specialized structures called 'junctions'. They ensure cell cohesion and regulate exchanges across the space between cells. Researchers have studied the role of a specific protein, gamma-actin, in the organization and mechanics of epithelial cells and their junctions. Their work reveals a mechanism of interdependence of different forms of the cytoskeletal proteins actin... Read more ›

While researchers have long been familiar with the surface structure of lymphatic vessels, a groundbreaking study has now focused on their jigsaw puzzle-like pattern. This arrangement helps cells tolerate changes in fluid pressure, such as swelling. Similar cell shapes are found on the surface of plant leaves, and the principle has been employed in human-led design as well. Read more ›

Memristors consume extremely little power and behave similarly to brain cells. Researchers have now introduced novel memristive that offer significant advantages: they are more robust, function across a wider voltage range, and can operate in both analog and digital modes. Their unique properties could help address the problem of 'catastrophic forgetting,' where artificial neural networks abruptly forget previously learned information. Read more ›

A long-term Switzerland-wide study has found that neighbourhoods with numerous, well-arranged trees exhibit lower mortality risks than other areas. The reasons behind this, and the factors that play a role, will require further research. Read more ›

Astronomers have detected oxygen in the most distant known galaxy, JADES-GS-z14-0. This record-breaking detection is making astronomers rethink how quickly galaxies formed in the early Universe. Read more ›

Lithium-6 is essential for producing nuclear fusion fuel, but isolating it from the much more common isotope, lithium-7, usually requires liquid mercury, which is extremely toxic. Now, researchers have developed a mercury-free method to isolate lithium-6 that is as effective as the conventional method. Read more ›

According to a predictive model, the microalgae present in peat bogs could offset up to 14% of future CO2 emissions, thanks to their photosynthetic activity. This conclusion was reached by basing the work on in situ experiments and the various predictive scenarios established by the IPCC. It is the first model to quantify the potential compensation of future CO2 emissions by peatlands on a global scale. This result lifts the... Read more ›
