A new therapy designed at Penn State has turned one of cancer's tactics against it. The team camouflaged a cancer-killing drug using cells from the tumor itself, allowing them to sneak medicine past the tumor’s defenses like a nanoscale Trojan horse and deliver a killing blow from the inside.

If wines such as cabernet sauvignon contain high amounts of chemical compounds known as alkylmethoxypyrazines (MPs), their fruity/floral bouquet can be overwhelmed, resulting in an off-putting flavor and aroma. Now, scientists have used magnetic nanoparticles to remove MPs from wine.

Here on Earth, 80 years of advertising has told us that diamonds are special, but our shiny stones have nothing on the weird and wonderful forms seen out in space. Now, astronomers have found that mysterious microwave signals around stars could be caused by swirling clouds of diamond dust.

Not only are large scars often unsightly, but the stiff scar tissue can also limit a person's range of motion, causing discomfort. And although there are procedures that minimize scarring, it's not always apparent if such measures need to be taken. New nanoparticles could help doctors decide.

Those diagnosed with glioblastoma don’t have many treatment options – and usually a median life expectancy of just over a year. Now, researchers at MIT have developed nanoparticles that could provide hope, crossing the blood-brain barrier and delivering two types of drugs to fight tumors.

New research led by Swansea University has found a novel way to wring more health benefits out of tea, by making quantum dots from tea leaves and using them to slow the growth of lung cancer cells.

Most solar cells only capture the visible light. Now, researchers at Berkeley Labs have developed a way to use nanoparticles coated in special organic dyes to convert near-infrared light into visible light, which could allow solar cells to harvest more of the spectrum.

Major internal bleeding is a very serious condition that requires immediate attention, and it's difficult to treat non-surgically. Scientists from Russia's ITMO University are working on an effective means of doing so, however, in the form of injectable magnetic nanoparticles.

Scientists have noticed a reduced incidence of cancer in patients suffering from the hereditary neurodegenerative condition Huntington’s disease. Now a team has uncovered how the disease could also be killing cancer cells, and how this could be harnessed for a new cancer treatment.

Researchers have developed a new technique to make metamaterials with nanoscale structures that can be tuned with strange optical properties. Using DNA-modified gold nanoparticles, the team could change the material's color, opening the door for new sensors or cloaking devices.
