Today's science news spans the cosmic and the computational. A toy universe suggests time might be a quantum illusion, while NASA plans an unprecedented rescue of a falling space telescope. The AI consciousness debate gets a skeptical take, and a landmark HPV vaccine study shows near-zero cervical cancer risk for vaccinated young women.
Two stories challenge our understanding of reality and our ability to operate in space.
An experiment with ultracold atoms in a 'toy universe' suggests time may be an emergent property from quantum entanglement, not a fundamental feature of reality.
NASA's Swift Observatory is falling out of orbit after 20 years, and the agency is partnering with Katalyst Space for a rapid rescue mission to boost it back to a stable altitude.
A major public health win and a nuanced look at sex differences round out the day.
A landmark UK study shows girls vaccinated against HPV at 12-13 have close to zero risk of cervical cancer death by age 30, with no deaths recorded in that age group since 2020.
An interview with the author of 'A Billion Years of Sex Differences' argues for a nuanced view of biological sex differences, rejecting both denial and extreme determinism.
From repurposed phones to AI consciousness, computing stories raise questions about what we build and how we think about it.
UC San Diego and Google are building a compute cluster from 2,000 retired Pixel phones, showing how old devices can become a low-cost, low-carbon computing platform.
The Atlantic argues that despite sophisticated language, AI models like Claude are not conscious, and anthropomorphizing them leads to dangerous conclusions.

Google Can't Math Parsecswww.jefftk.com
Google's calculator has a bug where it incorrectly calculates the parsec unit. The article explains what a parsec is (a unit of distance based on stellar parallax, where a star's apparent shift of one arcsecond corresponds to one parsec) and points out that Google's math on this
Severe drought, energy shortages and food insecurity: What El Niño could mean for Europe this yearwww.euronews.com
Climate scientists have confirmed El Niño has officially begun, warning of turbocharged weather globally. The phenomenon, occurring every 2-7 years due to warming sea surface temperatures in the Eastern Pacific, can push up global temperatures and fuel extreme events like heatwav
Duke University and IonQ Demonstrate Tripartite Entanglement of Remote Atomic Qubitsquantumcomputingreport.com
Researchers from Duke Quantum Center and IonQ have successfully demonstrated the distributed generation of a Greenberger–Horne–Zeilinger (GHZ) state — a form of tripartite quantum entanglement — across a three-node quantum network using trapped atomic ions. The experiment used th

Estudo de pesquisadores brasileiros, publicado no Journal of Systematics and Evolution, mapeou o fenômeno evolutivo da perda do canto dos grilos. A pesquisa mostra que mudanças no habitat e a pressão de predadores estão atuando para tornar esses insetos mais silenciosos ou totalm
NASA's Parker Solar Probe detected unexpectedly high-energy protons while passing through the solar corona during perihelion encounters at the heliospheric current sheet. These energetic particles far exceeded what existing models of particle acceleration could predict. A researc
