Using chemistry and nanotechnology, researchers at Harvard and Brigham and Women’s Hospital designed a super-sized Cisplatin molecule able to deliver toxic platinum atoms to tumors while proving nontoxic to kidneys.  The research was conducted on laboratory animals.
Cisplatin is a powerful anti-cancer drug used in first-line chemotherapy but with limited use because of its toxicity. The team designed a polymer what would bind to Cisplatin, making it wrap itself into a 100 nanometers ball, too large to enter the kidneys, lungs, liver and spleen.  Once the molecule reached the tumor it …

Listening to an MP3 player can be harmful to your hearing sensitivity, according to a recent study at the Ghent University, involving 10 men and 11 women with ages between 19 and 28 years.
According to the study authors: “Excessive noise exposure can lead to metabolic and/or mechanical effects resulting in alterations of the structural elements of the organ of Corti [the inner ear organ in mammals that contains auditory sensory cells or 'hair cells']. The primary damage is concentrated on the outer hair cells, which are more vulnerable to acoustic …
