Located just off Regent’s Park, the subterranean ice-well would have been one of the largest of its kind when first built -- measuring an impressive 24.6 foot (7.5 m) wide and 31.2 foot (9.5 m) deep. The structure survives in good condition, with an intact brickwork interior and retains its circular plan and principal features including a ventilation hole or opening, a red brick lined chamber, an entrance-passage, an ante-chamber and evidence of internal chambers.

Just over 24 hours before its closest approach to Ultima Thule, New Horizons has sent back the first images that begin to reveal Ultima Thule’s shape. Image-sharpening techniques combining multiple images show that Ultima Thule is elongated, perhaps twice as long as it is wide. The spacecraft was approximately 1.2 million miles (1.9 million km) from Ultima Thule when this image was taken on December 30, 2018.

Wedell-Neergaard et al show that in abdominally obese people, exercise-mediated loss of visceral adipose tissue mass requires interleukin-6 (IL-6) receptor signaling. Given that abdominal fat is metabolically harmful to health, the study raises a potentially important side effect of IL-6 receptor antibodies, such as tocilizumab.
