Connie K. Ho for redOrbit.com - Your Universe Online Researchers at the Massachusetts Institute of Technology (MIT) recently revealed a new platinum compound that could eliminate cancer cells more effectively than cisplatin, a popular chemotherapy anticancer drug. Drugs that have platinum are the most widely used most powerful cancer drugs. On the downside, these agents have toxic side effects and the cancer cells can eventually become resistant; as such, the new discovery is exciting for...

Researchers at Brigham and Women's Hospital (BWH) are the first to report a new approach that integrates rational drug design with supramolecular nanochemistry in cancer treatment. Supramolecular chemistry is the development of complex chemical systems using molecular building blocks. The researchers utilized such methods to create nanoparticles that significantly enhanced antitumor activity with decreased toxicity in breast and ovarian cancer models. "This work is effectively moving...

A new study by University of Kentucky researchers shows how light and strained ruthenium-based drugs may be more effective at fighting cancer cells and less toxic to healthy cells than a similar and widely used drug. Cisplatin is a common platinum-based cancer drug. But while cisplatin kills cancer cells, it also attacks healthy cells, causing debilitating side effects. Ruthenium is a rare transition metal also belonging to the platinum group of the periodic table, and the UK researchers...

Antonio de Ulloa was born on January 12, 1716 in Seville. Ulloa enlisted with the Spanish Navy in 1733. In 1735, he was sent to Ecuador as a member of the French Geodesic Mission. The mission, led by Pierre Bouguer, was organized by the French Academy of Sciences to measure a degree of the meridian at the equator. He stayed in Ecuador for 9 years until 1744, during this stint; he discovered platinum with his partner, Jorge Juan. In 1745, he returned to Spain. However, while enroute to...

Platinum is a chemical element in the periodic table that has the symbol Pt and atomic number 78. A heavy, malleable, ductile, precious, gray-white transition metal, platinum is resistant to corrosion and occurs in some nickel and copper ores along with some native deposits. Platinum is used in jewelry, laboratory equipment, electrical contacts, dentistry, and anti-pollution devices in automobiles. Notable characteristics The metal is a beautiful silvery-white when pure, and malleable...
