We came across an excellent search engine for science students in the younger grades. Biology Questions and Answers is a website that discusses all branches and subjects of Biology. You can learn everything about Biology here! This site was specially written and organized to make Biology learning easier. More than 1800 questions and answers are available to help you study Biology in the easiest way possible.
The content is divided into all Biology branches: biochemistry, cell biology, microbiology, zoology, physiology, embryology, botany, genetics, evolution, ecology and diseases. Each of these branches are then subdivided into specific subjects, as listed below.

Remote-controlled protein factories
Engineered bacterial cells can churn out medically useful proteins such as insulin, the blood-clotting agent thrombin, and a host of other human enzymes and hormones. Plants, yeast and even other mammals can be given the genes needed to produce valuable proteins that they don’t make naturally. Most famously, even notoriously, genetically modified goats can secrete spider silk in their milk, which can be extracted and used to make tough fibres.
But in many ways this is taking a sledgehammer to a nut. If all you want is a particular protein – whose chemical structure in encoded within a gene in DNA – then even a bacterium is an awfully complicated bit of machinery to make it. Strictly speaking, all you really need to do the job are the DNA itself, the amino acids from which proteins are made, and the molecular machinery for translating DNA into proteins – in particular, an assembly of proteins and RNA called a ribosome, which builds the new protein molecules.

Science camp inspires kids
Fisher River First Nation, is one of about 45 students from communities across Canada participating in the camp at the University of Manitoba this week. It’s an annual event that takes place in different provinces every summer.
