This article discusses a study on the use of paper to create three dimensional (3D) models of tumors and damaged hearts in the laboratory. Conducted by chemist George Whitesides and his colleagues at Harvard University in Cambridge, Massachusetts, the study used a gel containing cells squirted onto small sheets of sterile chromatography paper. The study found that such models could demonstrate how tumors and damaged hearts respond to drugs.

The article presents information about Luk Van Parijs, an immunologist and associate professor of biology at the Massachusetts Institute of Technology (MIT). He was fired for research misconduct. According to MIT officials, Van Parijs admitted fabricating and falsifying data in a published paper. The toughest issue raised by this case is how to stop similar happenings in future. The researchers who first raised doubts about Van Parijs's behavior are to be applauded. The university began investigating Van Parijs more than a year ago when members of his research group complained.

The article reports that a team at the Massachusetts Institute of Technology in Cambridge has required diabetics to take a urine test every day using a filter paper. The purpose of the initiative is to ensure that the patients have taken their medication for six months. It states that the paper reacts to the substance of the drugs taken by the patients. It likewise informs that patients who miss fewer than five of their pills each month will receive a free call reward for their cellphones.

Visitors to Lene Hau's laboratory at Harvard University leave their shoes at the door. Dark state is neither light nor matter, nor a simple combination of non-interacting light and matter, says Ron Walsworth, who works on dark states at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts. In a paper to be published in "Physical Review Letters," later this year, Jeff Kimble and his colleagues at California Institute of Technology in Pasadena have shown how the dark state provides an unprecedented means to control and use the quantum properties of light.

The article focuses on a draft paper by researcher Vinay Deolalikar that might have solved the "P = NP" computer science problem. It states that "P = NP" is one of the seven Millennium prize problems by Clay Mathematics Institute which, if solved, could earn Deolalikar one million dollars. It mentions that "P = NP" concerns the speed which computers can accomplish tasks such as factorising numbers.

This article focuses on the efforts of bio-hackers Samantha Sutton and her colleagues of the Massachusetts Institute of Technology in Cambridge, Massachusetts, to launch a revolution that some believe will have as big an economic impact as the computer industry. Sutton is now building circuits from proteins rather than wires at the Massachusetts Institute of Technology. For Sutton and her colleagues, genes and proteins are components to be plugged together at will. They call themselves synthetic biologists, but their approach has little in common with traditional biology. INSETS: What about bad guys?;History repeats itself.
