The atom-smashing Large Hadron Collider’s successor will be 56 miles wide

CERN, the European Organization for Nuclear Research, has released a blueprint for the successor of the Large Hadron Collider (LHC).
The new particle accelerator, called Future Circular Collider (FCC), will have a diameter of over 56 miles, compared to the LHC's 17-mile diameter.
CERN hopes that the FCC will produce particles that are heavier and will allow for new discoveries in the field of physics.
The FCC is estimated to cost $16 billion and will require an independent review and a decision from CERN's member countries in 2028.

Apple picked as logo for celebration of classical physics in 2027

Physicists in the UK have proposed an International Year of Classical Physics in 2027 to honor Isaac Newton and the branch of physics that underpins much of everyday life.
The official logo for the International Year of Classical Physics is a bright green Flower of Kent apple, a tribute to Newton, who famously developed our understanding of gravity after watching an apple fall from a tree of that variety.
Crispin McIntosh-Smith, chief classical physicist at the University of Lincoln, aims to get endorsement for the International Year of Classical Physics from the United Nations.
The year will feature numerous outreach events and a gala launch ceremony in Grantham, closest to Newton's birthplace, as well as a scientific workshop in the grounds of Woolsthorpe Manor.

Radioactive gold nanoparticles could track drug distribution in the body

A new imaging technique using neutron-activated gold nanoparticles enables real-time visualization of drug distribution in the body without external tracers.
Gold nanoparticles are attractive for targeted drug delivery in cancer treatment and can accumulate in tumors.
Researchers in Japan are utilizing radioactive gold isotopes to image nanoparticle distribution in vivo.
The radioisotope 198Au emits 412 keV gamma rays, facilitating activation imaging for tracking nanoparticle movement.
Experiments involved injecting 198Au-based nanoparticles into mice tumors and using a hybrid Compton camera for imaging.

How writing a popular-science book led to a Nature Physics paper

Writing a popular-science book led to a Nature Physics paper on autonomous quantum machines and practical quantum thermodynamics.
The book Quantum Steampunk inspired the author to explore opportunities for the future of quantum thermodynamics.
While conventional thermodynamics accompanied the Industrial Revolution, quantum thermodynamics offered new insights but lacked practical applications.
Autonomous quantum machines access heat from the environment to power themselves without external control.
The author envisioned the need for a quantum SoCal—a setting where autonomous quantum machines can operate effectively.
Collaborating with experimentalist Simone Gasparinetti, they integrated an autonomous quantum refrigerator with a quantum computer.
The experiment demonstrated the quantum refrigerator's ability to cool qubits more efficiently than expected, reaching a temperature of 22 milliKelvin.
The success of the experiment led to a forward-looking review on useful autonomous quantum machines and the potential growth of a subfield.
The collaboration showed that publishing a popular-science book can indeed have a positive impact on one's research.
