A chemical signature long interpreted as evidence of a global shift in Earth’s carbon cycle may instead have formed through local interactions involving magma, hydrocarbons, and methane-eating microbes. The finding casts doubt on a widely used record of the planet’s oxygenation history.

Researchers found that scented cleaning products can react with indoor ozone within minutes, generating billions or trillions of nanoparticles. These particles can penetrate deep into the lungs, with some exposures potentially matching or exceeding the dose from heavy traffic.

Scientists used a 13-ion quantum simulator to recreate a particle-forming process associated with the extreme conditions of the early universe. The experiment indicates that quantum systems may eventually model how matter emerged and evolved after the Big Bang.

A chemical signature long interpreted as evidence of a global shift in Earth’s carbon cycle may instead have formed through local interactions involving magma, hydrocarbons, and methane-eating microbes. The finding casts doubt on a widely used record of the planet’s oxygenation history.
If the signature was local rather than global, scientists may need to revise how they

A reinterpretation of this marker could alter models of how oxygen reshaped early Earth and influenced the emergence of complex life.
Summary
Researchers found that scented cleaning products can react with indoor ozone within minutes, generating billions or trillions of nanoparticles. These particles can penetrate deep into the lungs, with some exposures potentially matching or exceeding the dose from heavy traffic.
Indoor air pollution can form after cleaning even when the original products appear to have

Household cleaning can create a hidden inhalation hazard rather than simply remove pollutants.
Summary
Scientists used a 13-ion quantum simulator to recreate a particle-forming process associated with the extreme conditions of the early universe. The experiment indicates that quantum systems may eventually model how matter emerged and evolved after the Big Bang.
The simulator does not recreate the universe itself, but it provides a controlled way to

Researchers found that trace amounts of lead in ancient ink can make writing inside carbonized papyrus visible in X-ray scans. The method could help recover Greek and Roman texts preserved by the eruption of Mount Vesuvius nearly 2,000 years ago.

Artemis II astronauts Victor Glover and Reid Wiseman are moving to emeritus status at NASA after traveling around the Moon. They will continue advising and mentoring teams as NASA prepares for Artemis III and later lunar missions.

Researchers found that blood flow to the brain rises before REM sleep begins, while neurons’ immediately available energy, measured as ATP, falls once REM starts. The result suggests that brain activity associated with dreaming may consume energy faster than it can be replenished.

Their continued involvement gives NASA a practical feedback loop as it moves from lunar flyby to sustained surface operations.
Summary
Researchers found that blood flow to the brain rises before REM sleep begins, while neurons’ immediately available energy, measured as ATP, falls once REM starts. The result suggests that brain activity associated with dreaming may consume energy faster than it can be replenished.
REM sleep appears to create a supply-demand mismatch in the brain: circulation increases, but usable
