Historical records of mercury (Hg) accumulation in lake sediments and peat bogs are often
used to estimate human impacts on the biogeochemical cycling of mercury. On the basis of …

Tendons are often injured and heal poorly. Whether this is caused by a slow tissue turnover
is unknown, since existing data provide diverging estimates of tendon protein half-life that …

Sub‐auroral electric fields play critical roles in energizing and transporting ring current ions,
