MU Scientists Find Cinnamon Can Replace Harmful Chemicals Used to Create Nanoparticles

MU scientists make strides in green nanotechnology

COLUMBIA, Mo. – Gold nanoparticles, tiny pieces of gold so small that they can’t be seen by the naked eye, are used in electronics, healthcare products and as pharmaceuticals to fight cancer. Despite their positive uses, the process to make the nanoparticles requires dangerous and extremely toxic chemicals. While the nanotechnology industry is expected to produce large quantities of nanoparticles in the near future, researchers have been worried about the environmental impact of the global nanotechnological revolution.

Study Suggests That Being Too Clean Can Make People Sick

ANN ARBOR, Mich.— Young people who are overexposed to antibacterial soaps containing triclosan may suffer more allergies, and exposure to higher levels of Bisphenol A among adults may negatively influence the immune system, a new University of Michigan School of Public Health study suggests.

Triclosan is a chemical compound widely used in products such as antibacterial soaps, toothpaste, pens, diaper bags and medical devices. Bisphenol A (BPA) is found in many plastics and, for example, as a protective lining in food cans. Both of these chemicals are in a class of environmental toxicants called endocrine-disrupting compounds (EDCs), which are believed to negatively impact human health by mimicking or affecting hormones.

Hamburger disease, a debilitating form of food poisoning, may be a thing of the past. New findings from an international research collaboration conducted by the French National Institute for Agronomic Research (INRA), involving the Université de Montréal are the first to show how the contaminating E.coli bacterium is able to survive in the competitive environment of a cow’s intestine by scavenging specific food sources. Published in this month’s Environmental Microbiology, and featured in Nature Reviews Microbiology, this study may lead to non-medicinal methods for eradicating this invasive bug. (more…)

Angeles Duran, 49-year-old Spanish lady has claimed to be the owner of Sun. Woman from Spain’s soggy region of Galicia said that she registered the star at a local notary public as being her property after learning about the American man, who registered moon and most planets in our solar system as his property.

Here is an international agreement, which states that no country may claim ownership of a planet or star, but it says nothing about individuals, she added.

“There was no snag, I backed my claim legally, I am not stupid, I know the law. I did it but anyone else could have done it, it simply occurred to me first,” she told the online edition of Spanish daily newspaper El Mundo. (more…)

Mammals Grew 1,000 Times Larger After the Demise of the Dinosaurs

NSF enabled the assembly of an international, interdisciplinary team that was the first to quantitatively document body size patterns over the past 100 million years

Researchers have demonstrated that the extinction of dinosaurs some 65 million years ago paved the way for mammals to get bigger, about a thousand times larger than they had been when dinosaurs roamed the earth. The study, released in the journal Science, is the first to quantitatively document the patterns of body size of mammals after the existence of dinosaurs. (more…)

How Pathogens Hijack Host Plants

Palo Alto, CA — Infestation by bacteria and other pathogens result in global crop losses of over $500 billion annually. A research team led by the Carnegie Institution’s Department of Plant Biology developed a novel trick for identifying how pathogens hijack plant nutrients to take over the organism. They discovered a novel family of pores that transport sugar out of the plant. Bacteria and fungi hijack the pores to access the plant sugar for food. The first goal of any pathogen is to access the host’s food supply to allow them to reproduce in large numbers. This is the first time scientists have a direct handle on controlling the food supply to pathogens and thus a new means to prevent a wide range of crop diseases and losses. (more…)
