How Nanotechnology May Be Damaging Our Lungs

How Nanotechnology May Be Damaging Our Lungs

 Nanomaterials may cause damage to the lungs

In 2006, The Woodrow Wilson International Center for Scholars published a warning and a challenge to the scientific community about its responsible use and handling of nanomaterials, as they were known to cause damage to the lungs.  Now, research conducted at the Chinese Academy of Medical Sciences in Beijing, has unveiled how the damage occurs and a possible means of control.

Harnessing Direct Solar Power To Propel Tiny Nanomaterial Machines

Harnessing Direct Solar Power

A four-finned rotor (center) floating on a pool of water spins when exposed to sunlight.

The sun is the most abundant source of renewable energy. But all the technologies that capitalize on sunlight, including photovoltaics and biofuels, require intermediate steps and infrastructure to turn the sun’s rays into something that can be used to perform work in a machine. Researchers at the University of California, Berkeley, are using carbon nanotubes to build small, simple waterborne machines propelled directly by sunlight. In theory, they say, these machines could be scaled up to make energy-generating pumps directly powered by the sun.

Nanotechnology In Dietary Supplements

Nanotechnology In Dietary Supplements 

The ability of the Food and Drug Administration (FDA) to regulate the safety of dietary supplements using nanomaterials is severely limited by lack of information, lack of resources and the agency’s lack of statutory authority in certain critical areas, according to a new expert report released by the Project on Emerging Nanotechnologies (PEN).
