Protein from poplar trees can be used to greatly increase computer capacity

Scientists from the Hebrew University of Jerusalem have succeeded in showing how it is possible to greatly expand the memory capacity of future computers through the use of memory units based on silica nanoparticles combined with protein molecules obtained from the poplar tree. In doing so, they say, they have developed an alternative avenue to miniaturize memory elements while increasing ... Read More »

American Society for Nanomedicine (ASNM) to Hold International Conference

There is enormous excitement and expectation surrounding the multidisciplinary field of nanomedicine – the science and technology of diagnosing, treating and preventing disease using nanotechnology. Nanomedicine is already influencing the pharmaceutical industry, especially in the design, formulation and delivery of therapeutics.  Current and future products range from nanoparticulate therapeutics that precision-target certain cancers to nanosensors that are capable of navigating ...

Lasers to Produce Better Nanotechnology Products

Particular GmbH, a new German nanotechnology company, is the first company to commercialize a novel process for the production of highly pure nanoparticles. The developments werde made at Laser Zentrum Hannover e. V. (LZH) and took five years. Niko Bärsch, CEO of Particular, explains that their nanoparticles make it easier to take advantage of nanotechnology for many products, especially in the field ... Read More »

New Report Reviews the Role of Food Science and Technology in Meeting the Needs of a Growing World Population

New Report Says Current Food Supply Must Drastically Increase in the Coming Decades Newswise — The world’s food system provides food for nearly seven billion people each day. But according to a new report from the Institute of Food Technologists (IFT), more advances are critical for an adequate food supply, which must nearly double during the next several decades, for ...

Reflections on the Safety of Nanotechnology-Based Sunscreens

A few weeks ago, I set Friends of the Earth a challenge—What is your worst case estimate of the human health risk from titanium dioxide and/or zinc oxide nanoparticles in sunscreens? The challenge came out of an article from FoE on nanomaterials and sunscreens, which I subsequently critiqued on 2020 Science. Georgia Miller and Ian Illuminto from FoE kindly responded ...

A Magnetic Remote Control That Can Rewind a Worm's Wriggle

The power to control living things and objects from a distance is a popular supernatural talent in science fiction and fantasy: Witches fling spells at foes and X-Men send chairs and tables flying with telekinesis, for example. But when it comes to remotely controlling biological organisms, science has a few tricks up its sleeve, too—although there’s nothing metaphysical about them. ... Read More »

Can Humans Survive?

Humans have survived ice ages and deadly pandemics to become the dominant species on Earth, even if our reign over the planet barely represents a blip in a geological record that has seen countless living organisms come and go. We have adapted to live almost anywhere, and have harnessed the power of nature by splitting atoms and splicing DNA to ... Read More »
