New Food Scare: Nano-Powder on Your Donuts: Should You Worry?

“There are nano-sized particles in your food. Does this make you nervous?” Continue reading

Nanotechnology: Armed resistance

Nature assesses the aftermath of a series of nanotechnology-lab bombings in Mexico — and asks how the country became a target of eco-anarchists. Continue reading

Why wood pulp is world’s new wonder material

THE hottest new material in town is light, strong and conducts electricity. What’s more, it’s been around a long, long time. Continue reading

Super-Strong, High-Tech Material Found to be Toxic to Aquatic Animals by Researchers at MU and USGS

Carbon nanotubes hold promise for industry but need monitoring, say researchers Continue reading

Nanoparticle ‘risk’ to food crops

A pair of widely used chemicals in the form of tiny “nanoparticles” have been shown to spread throughout a crop plant or affect growth and soil fertility. Continue reading

Sunlight May Trigger Nanoparticle Formation

Nanoparticles found in the environment could come from natural processes, not just from man-made sources. In rivers and other bodies of water, sunlight can help dissolved organic matter reduce silver and gold ions to form nanoparticles of the metals, according to researchers in China (ACS Nano, DOI: 10.1021/nn302293r).

Hmm… is there any place on earth which is naturally free from nanoparticles? Continue reading

White House Blocking EPA Efforts to Issue Rules on Nanomaterials, Advocates Say

I’m good with the idea of nanotech oversight. EPA, not so much. Environmental and other assorted “advocates,” not at all under any circumstance. Continue reading

Nano-subs built to grab and move oil spills to collection site

Scientists say they have built a self-propelled “microsubmarine” that can scoop up oil from contaminated waters and take the droplets to a collection facility. Continue reading

EU to Address Risks of Chemical Mixtures, Endocrine Disruptors, Nanosubstances

The European Union is preparing to build on the REACH law and related legislation to address concerns about chemicals in three areas considered to be insufficiently regulated: endocrine disruptors, the combined effects of chemical mixtures, and nanosubstances. Continue reading

Study Links Plant Damage to Nanoparticles

Science fiction might have us believe that tiny particles seeping into soil and altering plant DNA will lead to the rise of giant killer tomatoes. But a new study suggests that exposure to certain nanoparticles may in fact have a shriveling effect on some plants. Continue reading

A Model To Predict Nanoparticle Toxicity

Nanomaterials: Researchers link semiconductor particles’ electrical properties and ability to cause inflammation Continue reading

Nanotech filters ‘could boost superbugs’

The rise of antibiotic-resistant “superbugs” could result from an increased dependence on nanomaterials in water treatment, Chinese researchers say. Continue reading
