Coronavirus outbreak likely now ‘gathering steam’
Harvard’s Marc Lipsitch said evidence indicates that the international cordon keeping coronavirus cases bottled up in China is a leaky one, and it’s likely that the relative handful of global cases reported so far are undercounted. If true, that will lead to widespread illness internationally, including in the U.S.

Ultraviolet corona discharges on treetops during storms
Penn State experts in meteorology and atmospheric science made their way down the nation’s eastern coast in June 2024 in search of corona discharges, a long-hypothesized atmospheric weather phenomenon where miniscule pulses of electricity dance at the tips of tree leaves, causing the canopy to glow in the ultraviolet…

Exercise, fasting shown to help cells shed defective proteins
A new study from the Blavatnik Institute finds that intense exercise and fasting activate hormones that boost cells’ capacity to dispose of defective proteins, which clog up the cell, interfere with its functions, and, over time, precipitate diseases including neurodegenerative conditions such as ALS and Alzheimer’s.
