Science Experiments on Environmental Education and Biology
A lot of organisms emit light. Of course you know fireflies, but there are also otherluminescent organisms such as some fishes, mushrooms, bacteria, dinoflagellates, andshellfishes. The culture of luminescent bacteria is not difficult. What you have to do isto get a strain of luminescent and harmless bacteria and raise it in a suitable culturemedium. A bacterium widely cultured and used also for lessons in schools is the Photobacteriumphosphoreum, now renamed: Vibrio phosphoreum.
Search for information about the mechanism of the bioluminescence. You can findinformation for this culture and general information on the Internet at sites listedlater. There is a lot of information on bioluminescence on the Internet. There are evenamateur sites devoted to this topic. You can buy the Vibrio phosphoreum at commercially,such as the ATCC (American Type Culture Collection) .You can find other firms of this type on the Internet, using the keywords: culturecollection. Also try the links for the protists experiment. These companies also supplythe culture media and in their sites you can often read their composition.
: In these experiments, need thehelp of a biologist to avoid culturing dangerous microorganisms. Even with help, keep thecultures only for a short time, wash your hands, wash and disinfect all tools which havebeen in contact with the cultures.

Are the insects which fly around lamps at night attracted by light or heat? To find out,use a clothing iron and an electric lamp. The electric lamp produces light with a littleheat, the iron produces only heat. Put both on a table. Keep them at least a meter (abouta yard) apart and with the emitting surfaces turned away from you. Note the differentbehavior of insects. Mask the lamp with plastic sheets of different colors and verify ifbugs are more attracted to a particular color. This is also a method to capture nighttimeinsects, particularly moths, so you can observe them with a lens or a stereoscopicmicroscope.

Many people have a smartphone, and most of us have heard of smart homes. But the average person isn’t aware that studies are being done with material to produce smart clothes. The future may mean that certain material used for clothing can light up or collect energy. Some types of fiber may be able to detect pollution and even give information over the internet. The biggest problem currently facing these materials is the fact that because they have been treated with chemicals, they currently wear out very quickly. The good news is that it has now been found how to grow cotton fibers that have these functions growing into them. If the science holds up, then eventually it will mean that cloths will be lighter while also being stronger and brighter and they won’t wear out.
It has been proposed that cyanobacteria — which obtain their energy from a highly efficient form of photosynthesis — might hold the key to increasing the yield of our most important crops and vegetables.

A science paper was set to go to press when the editor’s found some mistakes in its supplemental material that led to their expressing some concern, and they wanted to get clarification from the original authors. The author, who is a chemist at The responded saying that the eras were a mistake in the names of the pigments. He went on to say that he was working with the editors of the journal to fix the problem.

Beckman Coulter Life Sciences launched a family of FormaPure reagent kits for extracting nucleic acid from often challenging formalin-fixed, paraffin-embedded (FFPE) tissues. FormaPure reagent kits represent a single chemistry system designed and optimized for use in next-generation sequencing (NGS) and other downstream applications, including qPCR/ddPCR/PCR.

To begin, the scientist started with cotton plants that were instead of those growing in a field. They then took the cotton fibers and cultured them separately which allowed a bypass of the normal process the plant uses for photosynthesis which makes sugar that it needs to grow. They gave the plants what they needed by feeding it with water that had glucose molecules along with the functional molecules they wanted it to absorb that then passed it all to the cells that build cotton fibers.

Physics () is a new and free online journal launched by the American Physical Society in 2008. Similar to Faculty of 1000 (), experts of the respective research areas summarise recent discoveries and explain it to the wider public. Physics publishes 3 types of articles of which 2 are particularly suitable for the interested physics teacher. The shortest ones, called synopses, are written by the editorial staff and summarise important papers in about 200 words. The second type describes exciting trends in selected areas of physics in around 3000 words. Articles are richly illustrated and edited for clarity and readability. The simple internal search machine returns a list of relevant articles, each with an illustrative icon, which can subsequently be restricted by article type.
