Programmed Nanorobots Seek And Destroy Cancer Tumors

nanorobots

Nanorobots have been successfully programmed to shrink tumors by cutting off their blood supply. This major advancement came from Arizona State University (ASU) scientists, in collaboration with researchers from the National Center for Nanoscience and Technology (NCNST), of the Chinese Academy of Sciences. The demonstration of the technology, the first-of-its-kind study in mammals, used breast …

A Transporter Protein For Pumping Antibiotics Into Bacteria

transporter protein EmrE

A cellular pump known to move drugs like antibiotics out of E. coli bacteria has the potential to bring them in as well, researchers in the University of Wisconsin-Madison Department of Biochemistry have discovered. The finding could revise almost 50 years of thinking about how these types of transporters function in the cell. Cells must …

Laser Triggered Nanoshells Deliver Drugs Inside Tumors

light-activated nanoshells

Researchers have developed a method for delivering cancer-killing drugs inside tumors with gold nanoparticles they can activate remotely using a laser. The researchers employed gold nanoshells to deliver toxic doses of two drugs — lapatinib and docetaxel — inside breast cancer cells, showing they could use a laser to remotely trigger the particles to release …

Improving Magnesium Borohydride For Solid-state Hydrogen Storage

Magnesium Borohydride

The key mechanism by which magnesium diboride (MgB2) absorbs hydrogen has been discovered by scientists at Lawrence Livermore National Laboratory (LLNL). The work, through theory and experimentation, also provides important insights into the reaction pathway that converts MgB2 to its highest hydrogen capacity form, magnesium borohydride (Mg(BH4)2). Mg(BH4)2 is a particularly promising hydrogen storage material …

Dark Exoplanet WASP-12b Devours 94 Percent Of Visible Starlight

WASP-12b

An exoplanet located beyond our solar system observed by NASA’s Hubble Space Telescope appears as black as asphalt because it “eats” light rather than reflecting it back into space, new research suggests. This light-eating ability is due to the planet’s unique prowess at trapping at least 94 percent of the visible starlight falling into its …
