U.S. uranium production in 2024 was highest in six years

Companies in the United States produced more uranium concentrate in 2024 than in any year since 2018 after a sustained period of higher uranium prices spurred production, according to our recently published Domestic Uranium Production Reportβ€”Quarterly. The increase largely came from two inβ€”situ recovery facilities, one in Texas and one in Wyoming, and the resumption of uranium production at White Mesa Mill in Utah, the only operational uranium mill in the United States. Production in the fourth quarter of 2024 alone was higher than the total annual production for each of the years in 2019–23.

Novel point-of-care technology delivers accurate HIV results in minutes

The technology described uses a nanomechanical platform and tiny cantilevers to detect multiple HIV antigens at high sensitivity in a matter of minutes. These silicon cantilevers are cheap and easy to mass produce and can be readily equipped with a digital readout. Built into a solar-powered device, this technology could be taken to hard-to-reach parts of the world where early detection remains a challenge to deliver fast interventions to vulnerable populations without waiting for a lab.

Scientists unveil starfish-inspired wearable tech for heart monitoring

When we move, it's harder for existing wearable devices to accurately track our heart activity. But researchers found that a starfish's five-arm shape helps solve this problem. Inspired by how a starfish flips itself over -- shrinking one of its arms and using the others in a coordinated motion to right itself -- scientists have created a starfish-shaped wearable device that tracks heart health in real time.

First guideline on newborn screening for cystic fibrosis calls for changes in practice to improve outcomes

The United States Cystic Fibrosis Foundation released the first guideline on newborn screening for cystic fibrosis (CF), in order to improve timely detection of CF in infants from all racial and ethnic backgrounds. The new guideline reflects rigorous scientific investigation and perspectives from parents, CF specialists, public health representatives, primary care providers and genetic counselors.

Galaxies die earlier than expected

For a long time, scientists thought that only actively star-forming galaxies should be observed in the very early Universe. The James Webb space telescope now reveals that galaxies stopped forming stars earlier than expected. A recent discovery deepens the tension between theoretical models of cosmic evolution and actual observations. Among hundreds of spectra obtained with the Webb program RUBIES, the team has found a record-breaking galaxy that had already stopped forming stars during an epoch where galaxies are normally growing very rapidly.

Gold battles cancer

Precious metals are not merely ornaments; they are also important components of pharmaceuticals, like the antitumor drug cisplatin. Recently, the search for alternatives with improved activity has begun to focus on gold. A research team has now published a study about the speciation and distribution of an organogold(III) complex in cancer cells and reveals how specially designed 'organogold' complexes might open exciting avenues for fighting cancer.

Seeing humanity's transition from hunting to farming as a cultural shift

Using a mathematical model, researchers have shed new light on the transition from hunter-gatherer to farming societies. Rather than focusing exclusively on external factors, they looked at internal demographics and the significant impact of human interactions. The model identified potential societal outcomes based on demographic changes, emphasizing aspects such as migration rates, cultural assimilation and the role of mortality in these transitions. The researchers aim to further develop their model with the aim of making it a standard tool for studying historical demographic interactions.
