Large-scale study of North American eagles reveals unexpectedly high frequencies and population-level consequences of lead poisoning

A large-scale study of North American eagles found unexpectedly high frequencies of both chronic and acute lead poisoning. The study revealed that adults are more frequently chronically poisoned than younger species, and that regional trends play a significant role in the frequency of lead exposure.

A boost to sulfur metabolism

A recent study by ITQB NOVA scientists uncovered the crucial role of a small marker protein, DsrD, in increasing metabolic activity for sulfate respiration. The findings suggest that DsrD acts as an allosteric activator of the DsrAB dissimilatory sulfite reductase, enhancing energy efficiency in microbial metabolism.

Core strength could help dogs avoid knee injuries

A study of over 1,200 agility dogs found that core strength exercises and balance activities can lower the risk of cranial cruciate ligament ruptures. Dogs that engage in high-level agility events and flyball are at higher risk, while those with certain breeds and age factors may also be more prone to injury.
