Nanoparticle therapy targets lymph node metastases

Wed, 08/14/2019 - 21:07
Metastasis, in which cancer cells break free from the primary tumor and form tumors at other sites, worsens the prognosis for many cancer patients. The lymph nodes -- glands of the immune system located throughout the body -- are typically the traveling cells' first destination. Now, researchers have developed a strategy to target metastases in lymph nodes for destruction, before they can cause cancer at other locations.

Solving the big problem of measuring tiny nanoparticles

Wed, 08/14/2019 - 19:03
Tiny nanoparticles play a gargantuan role in modern life, but experts have struggled to reach a consensus on the best way to assess and measure them. Scientists have concluded that measuring the range of sizes in nanoparticles -- instead of just the average particle size -- is optimal for most applications.

Scientists can now control thermal profiles at the nanoscale

Sat, 08/10/2019 - 01:08
Scientists have designed and tested an experimental system that uses a near-infrared laser to actively heat two gold nanorod antennae to different temperatures. The nanorods are so close together that they are both electromagnetically and thermally coupled. Yet the team measured temperature differences between the rods as high as 20 degrees Celsius and could change which nanorod was cooler and which was warmer, even though the rods were made of the same material.

Calcium: Good for bones, good for cultural conservation

Wed, 08/07/2019 - 17:56
When it comes to cultural heritage sites, there are few things historians wouldn't do to preserve them for future generations. In particular, stone buildings and sculptures made of plaster and marble are increasingly at risk of damage from air pollution, acid rain and other factors. Researchers now report a new, calcium-based conservation treatment inspired by nature that overcomes many drawbacks of currently used methods.
