breath sample reflects the same portion of exhaled air.” For additional details, see the original ETH Zurich press release here and the Futurity article Hand‑held gadget measures fat burning via breath.

spectroscopic studies missed the demon because their momentum resolution was insufficient; the M‑EELS instrument employed here achieved roughly five‑fold finer momentum discrimination, enabling the detection. Nevertheless, the current theoretical...

Polar Biology, and additional context on the challenges of surveying remote Arctic waters is available in a related article here.

field could have re‑accreted into the small moons and rings we observe today. “Phyllosilicates had never been detected anywhere in the outer solar system beyond Jupiter, so that was not on our list of things to look for,” notes Davis, now a postdoctoral...

the launches… I don’t at this time anticipate that’s going to create a cost problem for us, but we do have some uncertainty here that we’ve got to work with NASA to get that put to bed.” NASA’s safety and performance criteria will determine whether the...

object, allowing researchers to infer the presence of a black hole even without direct visual evidence. See an example here. Imagining Black Holes as Propulsion Engines Beyond confirming their existence, scientists have speculated about using black...

Journal Letters Expanding the sample of such events will clarify whether the pre‑explosion mass‑loss signatures observed here are typical of stripped stars or represent a more diverse set of evolutionary pathways. “Going forward, I’m excited to observe...

experiments have already revealed several high‑pressure phases within Earth’s mantle, but the simulations presented here predict an additional transformation, termed post‑post‑spinel. This phase becomes thermodynamically stable at pressures that exceed...

New data shows Pluto’s atmosphere is shifting unexpectedly, sparking fresh investigations into the dwarf planet’s evolving climate. New observations suggest Pluto’s tenuous atmosphere is beginning to thin as the dwarf planet drifts farther from the...

yet the period remains poorly documented because of scarce textual evidence. Physical remains from the Mljet wreck therefore provide crucial data to fill gaps in our understanding of early medieval trade and elite mobility. “It’s a blank,” said...

holes. A team of astronomers has reported what may represent the earliest example of a “black‑hole star,” a compact system where a fast‑growing black hole is enveloped by an unusually dense, dust‑free gas shell. Detected at a time when the universe was...

patients or ecosystems—a concern underscored by recent discussions of AI’s ethical and legal ramifications in healthcare here. We should insist that researchers disclose their use of automated tools, that they are responsible for the veracity of their...

beyond theoretical predictions. For decades, theorists predicted that abruptly altering a material’s properties everywhere could make a propagating wave behave oddly, but experimental verification remained elusive. The notion was that a wave...

no longer laid out in spacious, solitary arrangements. Instead, researchers observed a transition to vertical stacking, where corpses were carefully placed atop existing remains. This was not a breakdown of tradition, but rather an adaptive use of space...
