Phys.org / Sugar-coated sensor sniffs out look-alike molecules in the air
Scientists have designed a new type of gas sensor that can tell apart "mirror image" versions of the same smell molecule, even at very low concentrations. By coating carbon nanotubes with custom-built sugar-based receptors, ...
Phys.org / Sticky beginnings: Surface-bound gels may explain life's origins on Earth
How did life begin? An international team of researchers from Japan, Malaysia, the UK, and Germany suggest that the answer may lie in sticky, surface-bound gels that existed long before the first cells.
Phys.org / Nature's greatest method actors: The insects that cosplay bumblebees
Deception is everywhere in nature. Animals and plants routinely cheat, lie and manipulate for their own benefit. One example is mimicry, where one species (the mimic) has evolved to resemble another (the model).
Medical Xpress / Newly expanded interactive map reveals peripheral artery disease amputations across the US
The PAD Collaborative, a group of 17 organizations convened by the American Heart Association to address the growing burden of peripheral artery disease (PAD) in the United States, has released a new and expanded version ...
Medical Xpress / Changing sweet taste in diet does not affect sugar cravings or health, study suggests
Changing the amount of sweetness in a person's diet has no impact on their liking for sweet foods, the results of a new trial suggest. The results also showed no difference in indicators of cardiovascular disease or diabetes ...
Phys.org / Noise-proof quantum sensor uses three calcium ions held in place by electric fields
Researchers at the University of Innsbruck have shown that quantum sensors can remain highly accurate even in extremely noisy conditions. It's the first experimental realization of a powerful quantum sensing protocol, outperforming ...
Phys.org / City raccoons showing signs of domestication
That resourceful "trash panda" digging through your garbage may be more than just a nuisance—it could be a living example of evolution in progress.
Phys.org / Gaia constraints on a 10 Myr nearby supernova
What can an ancient supernova teach scientists about Earth and celestial objects? This is what a study recently published in Astronomy & Astrophysics hopes to address as a team of scientists investigated the interaction of ...
Phys.org / HIE-ISOLDE: Ten years, ten highlights
The Isotope Separator On-Line facility (ISOLDE) directs a proton beam from the Proton Synchrotron Booster (PSB) onto specially developed thick targets, producing low-energy beams of radioactive nuclei—those with too many ...
Dialog / Dislocations without crystals: Burgers vectors discovered in glass
For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without breaking. Their secret lies in tiny, line-like defects called dislocations, which move through ...
Phys.org / How to watch the last supermoon of the year
The last supermoon of the year will shine soon in December skies.
Phys.org / Rethinking urban communities: Transforming vacant spaces into vibrant places
Italian architect and researcher Dr. Chiara Mazzarella has long been captivated by the idea of finding better ways to use empty buildings. Across Europe, millions of homes and commercial buildings lie vacant, even as housing ...
