Lighting technology is in a state of change. Incandescent bulbs, which have been around forever, have been banned in the United States but the heavily-subsidized replacement, compact fluorescent bulbs, run the risk of mercury poisoning if they break and have a glow that many don't find appealing. Light emitting diodes (LEDs) are likely the technology of choice in the mid-term future but they are expensive.

(Inside Science) -- Sampling the waste in a city's sewage system can be a good way to study the microbes that live in the population's guts – and could even offer a way to monitor public health issues such as obesity, according to new research.
I am writing a book on mitochondria and after a few months of research you begin to see a common thread - serendipity. Sometimes big things happen because of what seems to be luck, a group of people all happen to be in one place at one time, they are all spurred on by each other and then dramatic things occur.
Soybean oil accounts for more than 90 percent of all the seed oil production in the United States and genetically modified (GM) soybean oil, obviously made from seeds of GM soybean plants, was recently introduced into the food supply with the benefit that it is healthier than conventional soybean oil.
Is it true?
Though people selling alternatives to science will use labels like "chemical-free", that is not really the case. Our world is entirely chemical.
'Chemical' has simply been turned into a bad word in 'if I cannot pronounce it, it must be bad' modern environmentalism catered toward wealthy elites. Are green alternatives actually less toxic? No, it turns out, and even worse is that because they claim a 'natural' basis, they are exempt from the labeling requirements of traditional products, so green consumers don't know the extent of the risk they are undertaking.
The Paleo diet is all made up, organic food just accepts one kind of genetic modification in its modern food over another, but booze? Yeah, scientists can really show how that was different in the past.
For almost a century, scientists have been puzzled by a process that is crucial to much of the life in Earth's oceans: Why does calcium carbonate, the tough material of seashells and corals, sometimes take the form of calcite, and at other times form a chemically identical form of the mineral, called aragonite, that is more soluble -- and therefore more vulnerable to ocean acidification?
Emulsifiers, which are added to processed foods to aid texture and extend shelf life, can alter the gut microbiota composition and localization to induce intestinal inflammation in mice that promotes the development of inflammatory bowel disease and metabolic syndrome, according to a new study.
The team fed mice two commonly used emulsifiers, polysorbate 80 and carboxymethylcellulsose, at doses seeking to model the broad consumption of the numerous emulsifiers that are incorporated into almost all processed foods. They observed that emulsifier consumption changed the species composition of the gut microbiota and did so in a manner that made it more pro-inflammatory.

Mosquitoes need blood to survive. And what better place to get a good meal than a slow, tasty human?
A new research project looked at how to create various non-spherical particles.
Non-spherical particles have a great deal of potential uses in industry because associated with their different shapes are properties such as large surface areas, high packing densities and unique responses to external electric and magnetic fields. Such properties can lend themselves to applications ranging from food processing, consumer goods such as cosmetics, absorbents, and drug delivery systems.
