Science brief
Martian Mantle Anomalies, Royal Society Honours, and Quantum Space Vacuum Breakthroughs
Orbital measurements reveal a molten Martian mantle, the Royal Society honors bacterial communication research, and NASA cancels Swift's rescue craft.
Science
Tidal tomography proved Mars' southern interior remains partially molten — overturning long-held models of a thermally dead Martian mantle.
BackgroundScientists analyzed minute gravitational perturbations measured by Mars orbiters over two decades. Solar tidal forces acting on the Martian interior allowed researchers to construct tidal tomography models of the mantle.
- Gravitational measurements revealed that the southern hemisphere mantle is 200°C to 400°C hotter than northern subsurface regions, creating a massive thermal asymmetry.
- The discovery confirms that parts of the Martian interior remain partially molten today, overturning long-standing assumptions of a completely cooled core.
- The heat anomaly provides new insights into historical subglacial water reservoirs, suggesting subsurface heat could have sustained microbial habitats far longer than assumed.

Awarding the Copley Medal for bacterial quorum sensing signals a major shift in medicine — targeting microbial communication offers a viable alternative as traditional antibiotics fail.
BackgroundFirst awarded in 1731, the Copley Medal is Britain's highest scientific honor, previously awarded to Charles Darwin and Dorothy Hodgkin. Quorum sensing describes how bacteria release chemical signals to coordinate collective behaviors like infection.
- Professor Bassler's research proved single-celled bacteria communicate across species lines, enabling them to coordinate behavior and act like multicellular organisms.
- Her discoveries enabled the development of novel anti-microbial therapies that disrupt bacterial signaling rather than relying on traditional antibiotic destruction.
- The award includes a £25,000 gift presented by the UK's national academy of sciences during its annual ceremonies in London.

The Roman Space Telescope's launch marks a milestone for US-European astronomy — deploying survey capabilities 100 times wider than Hubble to map dark energy.
BackgroundThe Roman Space Telescope is a flagship mission designed to investigate dark energy and survey exoplanets. The European Space Agency contributed key flight hardware, including specialized detectors, alongside deep-space communications support.
- The observatory's wide-field camera will map dark matter distribution across billions of galaxies, accelerating deep-space survey speeds beyond current capabilities.
- ESA's new 35-metre antenna in New Norcia will provide continuous data downlink support throughout the telescope's deep-space orbit.
- Roman's exoplanet survey will work alongside ESA's Euclid mission, using gravitational microlensing to detect thousands of distant world systems.

The failure of NASA's LINK docking craft ends the 22-year Swift mission — blinding a premier UK-backed observatory tracking cosmic gamma-ray bursts.
BackgroundLaunched in 2004 with primary instruments built by Leicester and UCL, Swift monitored cosmic gamma-ray bursts for over two decades. Elevated solar activity increased atmospheric drag, rapidly decaying the satellite's low-Earth orbit.
- The $30M LINK servicing craft developed attitude-control malfunctions during testing, preventing safe docking maneuvers with the tumbling satellite.
- Engineers confirmed Swift's orbit cannot be raised without intervention, ensuring atmospheric re-entry and destruction in late 2026.
- UK astrophysics teams expressed disappointment, noting Swift remained one of the world's most effective space observatories for detecting multi-wavelength cosmic explosions.
