Reimagining MRI contrast: Iron outperforms gadolinium

Rice University nanoscientists have demonstrated a method for loading iron inside nanoparticles to create MRI contrast agents that outperform gadolinium chelates, the mainstay contrast agent that is facing increased scrutiny ...

Nanobot pumps destroy nerve agents

Once in the territory of science fiction, "nanobots" are closer than ever to becoming a reality, with possible applications in medicine, manufacturing, robotics and fluidics. Today, scientists report progress in developing ...

Infrared sensor as new method for drug discovery

Using an infrared sensor, biophysicists at Ruhr-Universität Bochum (RUB) have succeeded in analysing quickly and easily which active agents affect the structure of proteins and how long that effect lasts. Thus, Prof Dr. ...

New nerve gas detector built with legos and a smartphone

Researchers at The University of Texas at Austin have designed a way to sense dangerous chemicals using, in part, a simple rig consisting of a smartphone and a box made from Lego bricks, which could help first responders ...

New laser technique may help detect chemical warfare in atmosphere

The Department of Homeland Security could benefit from a reliable, real-time instrument that could scan the atmosphere for toxic agents in order to alert communities to a biological or chemical attack. UCF optics and photonics ...

Study sheds new light on antibiotics produced by ants

Ants, like humans, deal with disease. To deal with the bacteria that cause some of these diseases, some ants produce their own antibiotics. A new comparative study identified some ant species that make use of powerful antimicrobial ...
