Lessons learned in history relate directly to lessons learned from everyday experiences. People developed and moved to the suburbs because more space was needed to start and expand families and because they wanted fresh air away from the industrial working environments that the cities provided. Today, it seems to take us longer to learn lessons. […]

Researchers at the UPV/EHU-University of the Basque Country and the BC3 (Basque Centre for Climate Change) are proposing measures to improve the environment and the efficiency of the tax system: CO2 emissions should be taxed and taxes on labor should be The effect that the introduction of environmental fiscal reform would have on an economic […]
New uses for recycled plastic — PET in this case — are beginning to emerge. See the following press announcement. Researchers at Singapore’s Institute of Bioengineering and Nanotechnology (IBN) and California’s IBM Research – Almaden (IBM) have discovered a new, potentially life-saving application for polyethylene terephthalate (PET), which is widely used to make plastic bottles. […]
Last week we provided an informational video showing one perspective — that of a natural gas company — concerning the debate about hydraulic fracturing. Here is another perspective, written by Don Lieber for Planetsave. [repostus]Silica — #8 In “Top 10 Toxic Ingredients Used By The Fossil Fuel Industries” Series (via Planetsave) This is one part […]
Gold-palladium nanocatalysts set new mark for breakdown and cleanup of nitrites Chemical engineers at Rice University have found a new catalyst that can rapidly break down nitrites, a common and harmful contaminant in drinking water that often results from overuse of agricultural fertilizers. Nitrites and their more abundant cousins, nitrates, are inorganic compounds that are […]
Paying the unneeded cost of heating a home in winter is never a welcome expense, especially if it’s a matter of clogged air filters affecting your home’s energy efficiency. Fortunately, this is a problem that can be addressed with a cost-effective solution called FilterWatch. Let’s start with this straightforward benefit: “A simple, effective energy efficiency […]
Synthetic biologists at Rice probe biochar’s impact on microbial signaling In the first study of its kind, Rice University scientists have used synthetic biology to study how a popular soil amendment called “biochar” can interfere with the chemical signals that some microbes use to communicate. The class of compounds studied includes those used by some […]
The following news report concerning the ineffectiveness of e-waste bans is disturbing. The challenge of understanding and safely managing e-waste worldwide is something that need to be responsibly addressed by everybody who is part of the supply chain, from designers to manufacturers and consumers. State e-waste disposal bans have been largely ineffective INDIANAPOLIS, Sept. 10, […]
Prototypes of the devices, which need no electricity or fuel, were the topic of one of the keynote addresses at the opening of the 246th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society. The meeting, which features almost 7,000 reports on new advances in science and other topics, continues through Thursday in the Indiana Convention Center and downtown hotels.
Over the past few years we have a long list of companies, technologies, or products that are worth knowing about. Unfortunately, they sometimes get buried too deeply in our archives so we provide fresh information for readers.
Our current technology of interest is dry ice blasting, a method for removing mold and preventing potential health-related illnesses. Carl Bennett provided this post last February.
Rice University nanotechnology researchers have unveiled a solar-powered sterilization system that could be a boon for more than 2.5 billion people who lack adequate sanitation. The “solar steam” sterilization system uses nanomaterials to convert as much as 80 percent of the energy in sunlight into germ-killing heat.
This is a low-priced ($39.00) and sustainable light that some 25 percent of the world’s population – living off the grid – needs. Why? So dangerous kerosene lamps can be relegated to museums only. The following mission statement comes from WakaWaka designers and manufacturer of what the company contends is the “most efficient solar lamp in the world.” The solar-powered light can provide 16 hours of light from a single day of sunlight.
The development of sustainable tools that utilize renewable energy is critical as we advance into the 21st century. We still need to meet the challenges of providing clean energy. Read the following story from Cranfield University about a solar stove developed by COMSATS Institute of Information Technology, Islamabad. A solar cooker able to harness the sun’s […]
Emmanuel Unuabonah and colleagues explain that almost 1 billion people in developing countries lack access to reliable supplies of clean water for drinking, cooking and other key uses. One health problem resulting from that shortage involves exposure to heavy metals such as lead, cadmium and mercury, released from industrial sources into the water. Technology exists for removing those metals from drinking water, but often is too costly in developing countries. So these scientists looked for a more affordable and sustainable water treatment adsorbent.
Inadequate waste disposal methods, contaminated water sources and the lack of awareness about proper hand-washing all contribute to the spread of waterborne disease. The pervasive threats in developing countries are bacteria and organisms that are commonly found in human or animal waste, which can contaminate water supplies when waste disposal areas are too close to drinking water sources. People who have ingested water contaminated with harmful organisms usually experience nausea, vomiting, diarrhea, dehydration – and in extreme cases, or in the very young – death.
