7.5 Stanford researchers convert lymphoma driver protein into cancer cell self-destruct switch¶

Stanford researchers engineered a molecule that hijacks BCL6, a lymphoma-promoting protein, and redirects it to trigger cancer cell apoptosis. In mice, the treatment completely eliminated aggressive human lymphoma tumors within 11 days.

7.5 Solar Orbiter traces magnetic switchbacks in solar wind to sun's surface¶

The European Space Agency's Solar Orbiter traced magnetic switchbacks in solar wind to their origin at the Sun's surface. Particle fingerprints indicate switchbacks form through interchange reconnection where different magnetic field types interact and snap open, releasing plasma.

Switchbacks originate at Sun's surface, not further out
Particles show evidence of interchange reconnection process
Closed magnetic loops interact with open field lines
Waves and turbulence occur after switchback leaves the Sun
