Thwarting deadly heart blockages with organic nanoparticles

Cardiovascular disease, which kills one Australian every 12 minutes, is caused by a hardening of the arteries due to abnormal deposits of fat and cholesterol (known as plaque) in the inner lining of the artery; a process ...

A remote control for neurons

A team led by researchers at Carnegie Mellon University has created a new technology that enhances scientists' ability to communicate with neural cells using light. Tzahi Cohen-Karni, associate professor of biomedical engineering ...

Extending nucleic acid memory (NAM)

Humanity is creating huge amounts of data every day, billions of emails and social media updates, new websites, documents, images, and scientific and commercial big data amounting to petabytes of storage needs and beyond. ...

Extraction of skin interstitial fluid using microneedle patches

Interstitial fluid is a major component of the liquid environment in the body and fills the spaces between the body's cells. In contrast, blood circulates only within the circulatory vessels of the body and is composed of ...

New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick ...

Cockle shells picked to treat dog cancer

The calcium mineral from which many shellfish, such as cockles, make their shells can be used to form nanoparticles. These nanoparticles can then be "loaded" with small drug molecules, such as anticancer drugs.

Membrane nanopore transport gets picky

Trying to determine how negatively charged ions squeeze through a carbon nanotube 20,000 times smaller than a human hair is no easy feat.

Breaking down stubborn cellulose in timelapse

Researchers at TU Graz in Austria have for the first time ever succeeded in visualizing at the single-molecule level the processes involved in a biological nanomachine, known as the cellulosome, as it degrades crystalline ...

New integrated device for nanometer-scale sensing

Researchers at Eindhoven University of Technology have developed a new, integrated optical sensor that provides increased resolution in measurements and paves the way for fully integrated and compact optical sensors including ...

Nanobowls serve up chemotherapy drugs to cancer cells

For decades, scientists have explored the use of liposomes—hollow spheres made of lipid bilayers—to deliver chemotherapy drugs to tumor cells. But drugs can sometimes leak out of liposomes before they reach their destination, ...
