A bee's venom contains several substances that destroycells. These includepeptidesandenzymesthat break through and destroy the layer offatslining each cell. The venom also destroys the skin'smast cells, which are part of the body's immune system. This releaseshistamine, which encourages blood ve...
Sacs called the gastric cacea hold enzymes and microbes that continue to digest the food. This extra digestive help is particularly important if the roach eats cellulose or wood. Only after the material is thoroughly broken down can the roach's midgut absorb the food's nutrients. Two segmented...
Bog gardens work best when they're developed with a plan in mind. Tossing some moisture-loving bulbs into a soggy area of your yard does not constitute a proper bog garden. Some of the most gorgeous bog gardens are created in order to give an adjacent pond soft, natural looking edges tha...
Maurice Michel is the 2023 winner of the Eppendorf Award for Young European Investigators. He is an assistant professor in the Science for Life Laboratory, Karolinska Institutet, Stockholm. Michel’s work has shown that a small molecule binding to the ac
What About Adding Pool Enzymes or a Winter Pill? Adding enzymes is optional, but I recommend doing it as an insurance policy to clear water. Pool enzymes help reduce the burden ofalgaecide by breaking down organic contaminants, making it easier for chlorine to kill. ...
The activation constant of Mg2+ is found to be substantially higher than that of MgdNTP; this work thus provides functional support for the additional low-affinity metal-binding site now known to be occupied by metal C. Article CAS PubMed Google Scholar Bakhtina, M. et al. Use of ...
By definition, you can't reason your way to anything really new, so you must journey into the unknown. 翻译: 如果你想发现新的事物,千里之行的第一步就是要学会与不确定性共存,并学会接受失败如常,因为寻找未知事物的风险...

A decaying body will even affect surrounding vegetation, killing off some flora with digestive enzymes. Forensic anthropologists can determine an individual's age, sex, race and body type by looking at the corpse's bones. There's normally not enough difference between genders in the skeletal ...
The remaining serotonin molecules in the cleft and those released by the receptors after use get destroyed by enzymes in the cleft (monoamine oxidase (MAO), catechol-o-methyl transferase (COMT)). Some get taken up by specific transporters on the presynaptic cell (reuptake). In the presynaptic ...
