the enzyme. With the T. brockianus extremozyme, hydrogen peroxide decomposes safely, and wastewater needs no extra pretreatment. What's more, the enzyme lasts long enough to treat multiple batches of wastewater. Thompson didn't set out to find an enz...
Big, old fish key to restoring groundfish stocks
...vival, and provide the ability of reserves to help replenish
other marine areas nearby. If properly located, reserves might also address the distinct nature of groundfish populations in different geographic locations, they said. Exactly that type of "seeding" effect has now been documented with some population...
Discovery promises simpler therapy for sickle cell disease
... In patients who become anemic, blood transfusions replenish
the red blood cell supply in the body. The team further found that differences among patients in their ability to process nitric oxide in the blood correspond to the severity of their disease symptoms. That result might explain a long-standing puzzle...
Gene therapy for Parkinson's disease moves forward in animals

its dwindling supply of dopamine, sidetracking the destructive course of Parkinson's disease. But eventually the treatment can backfire. "Levodopa generally works great for several years, but then it actually starts creating movement problems," Mande...

...dy, they can theoretically divide without limit to replenish
cells lost due to everyday wear and tear, or following injury or disease. Dr Rod Rietze, head of the Queensland Brain Institute's (QBI) Laboratory for Neural Stem Cell Biology, is hoping those stem cells may soon unlock the secrets to healing the br...

Coral reef resilience: Better feeders survive bleaching
... M. capitata increased five-fold, allowing them to replenish
their energy reserves making it more likely that they'll survive and spawn after a bleaching event. "The results were a surprise," Palardy said. "Previous studies showed that thick tissue layers or mounded shapes made corals resilient. But we found ...
