For the first time, scientists have used satellite data to create a 3D map of the sun's interior magnetic field, the fundamental driver of solar activity. The research, published in The Astrophysical Journal Letters, should ...

Robots are getting better at sniffing out smells thanks to improvements in electronic noses (e-noses). A comprehensive review of the state of robot olfaction, published in the journal npj Robotics, has surveyed recent advances ...

Microglia are the brain's immune cells that clean out debris, such as damaged proteins and old cell parts, to keep the organ healthy. But the very properties that make these cells so useful might also be a driving factor ...

The promise of smart wearables is often talked up, and while there have been some impressive innovations, we are still not seeing their full potential. Among the things holding them back is that the chips that operate them ...

Whether it's digging up weathered bones from a paleontological site or reexamining forgotten trays in museum and university collections, the study of dinosaurs still throws up something new.

Deforestation is having a more devastating effect on the Amazon rainforest than earlier data suggested. While cutting down large swaths of trees destroys vital habitats, it also harms the region's ability to generate its ...

A simple smart speaker may be the latest tool to help seniors with some of the mental and physical challenges of type 2 diabetes. A new study published in JAMA Network Open reports that using an Amazon Echo Dot helped reduce ...

If something exists in nature, there is most likely a very good reason for it. While there are exceptions, many features "selected" by evolution serve a purpose. Take the blue manakin, a small bird commonly found in southeastern ...

After years of trying, scientists have finally created a stable superatom of copper, a long-sought-after chemical breakthrough that could revolutionize how we deal with carbon emissions.

Perovskite solar cells (PSCs) are known for their impressive ability to convert sunlight into energy, their low production costs and their lightweight design. They may well be the rising stars of renewable energy, but they ...

Seeing a satellite zip across the night sky can be a fascinating sight. However, what may be spectacular for people on the ground is becoming a major problem for astronomers. A new study published on the arXiv preprint server ...

When spider monkeys want to tell others about the best fruit trees in the forest or ones they've missed, they do so by changing their social groups to share what they know, according to a new study published in the journal ...

Humanoid robots look impressive and have enormous potential to change our daily lives, but they still have a reputation for being clunky. They're also heavy and stiff, and if they fall, they can easily break and injure people ...

Scientists led by a team from Fudan University in Shanghai have created a new flexible fiber chip as thin as a human hair. The development could usher in a new generation of even smarter wearables for a range of applications, ...

For the first time, physicists have generated and observed stable bright matter-wave solitons with attractive interactions within a grid of laser light.
