Nanoparticles Carrying Bee Venom Deliver Death Blow To HIV Virus
2013-03-08 12:17:41

Brett Smith for redOrbit.com - Your Universe Online According to a new report in the journal Antiviral Therapy, researchers from the Washington University in St. Louis have found that nanoparticles loaded with bee venom are capable of destroying the human immunodeficiency virus (HIV) while leaving the body´s cells unharmed. In a radical departure from traditional attempts to treat HIV, the research team says that the nanoparticles could be used to develop a prophylactic gel capable of...

Michael Harper for redOrbit.com — Your Universe Online In all advances in science and technology, researchers must first look back before looking forward. And there´s something about the natural shape and form of living creatures which have long been residents of Earth which cannot be improved upon, only mimicked. Hongbo Zeng, a chemical and materials engineering researcher at the University of Alberta, has been studying one creature in particular to find clues for new drugs...

In experiments mimicking a natural environment, Duke University researchers have demonstrated that the silver nanoparticles used in many consumer products can have an adverse effect on plants and microorganisms. Fifty days after scientists applied a single low dose of silver nanoparticles, the experimental environments produced about a third less biomass in some plants and microbes. These preliminary findings are important, the researchers said, because little is known about the...

Watch the video "Chemotherapy Drugs Getting Better at Targeting Cancer Cells" redOrbit Staff & Wire Reports - Your Universe Online Changing the shape of chemotherapy drug nanoparticles to make them rod-shaped rather than spherical can enhance their effectiveness in targeting and treating breast cancer cells by as much as 10,000-fold, according to new research from bioengineers at the University of California, Santa Barbara (UCSB). As part of the research, a team led by Samir...

Artificial atoms and bonds provide a new set of building blocks for future materials Northwestern University's Chad A. Mirkin, a world-renowned leader in nanotechnology research and its application, has developed a completely new set of building blocks that is based on nanoparticles and DNA. Using these tools, scientists will be able to build -- from the bottom up, just as nature does -- new and useful structures. Mirkin will discuss his research in a session titled "Nucleic...

New design uses silicon nanoparticles to improve capacity and recharge more quickly Researchers at USC have developed a new lithium-ion battery design that uses porous silicon nanoparticles in place of the traditional graphite anodes to provide superior performance. The new batteries–which could be used in anything from cell phones to hybrid cars–hold three times as much energy as comparable graphite-based designs and recharge within 10 minutes. The design, currently under a...

Two of the most widely used nanoparticles (NPs) accumulate in soybeans – second only to corn as a key food crop in the United States – in ways previously shown to have the potential to adversely affect the crop yields and nutritional quality, a new study has found. It appears in the journal ACS Nano. Jorge L. Gardea-Torresdey and colleagues cite rapid increases in commercial and industrial uses of NPs, the building blocks of a nanotechnology industry projected to put $1...

Metals contained in nanoparticles can enter into the food chain Scientists have, for the first time, traced the nanoparticles taken up from the soil by crop plants and analyzed the chemical states of their metallic elements. Zinc was shown to dissolve and accumulate throughout the plants, whereas the element cerium did not dissolve into plant tissue. The results contribute to the controversial debate on plant toxicity of nanoparticles and whether engineered nanoparticles can enter into the...

Every day scientists learn more about how the world works at the smallest scales. While this knowledge has the potential to help others, it's possible that the same discoveries can also be used in ways that cause widespread harm. A new article in the journal Nanomedicine, born out of a Federal Bureau of Investigation workshop held at the University of Notre Dame in September 2012, tackles this complex "dual-use" aspect of nanotechnology research. "The rapid pace of breakthroughs in...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
