Cambridge, Massachusetts - Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed a new system that allows Web users to share self-selected aspects of their online activity with their friends and the general public. The hope is to give users themselves, as well as academics and other scientists conducting research in the public interest, access to the same type of browsing data that big Web companies currently collect and mine to better target products to individual consumers.
Cambridge, Massachusetts - What are the prime factors, or multipliers, for the number 15? Most grade school students know the answer - 3 and 5 - by memory. A larger number, such as 91, may take some pen and paper. An even larger number, say with 232 digits, can (and has) taken scientists two years to factor, using hundreds of classical computers operating in parallel.
Cambridge, Massachusetts - In a study of worms, MIT neuroscientists have discovered a gene that plays a critical role in controlling the switch between alternative behavioral states, which for humans include hunger and fullness, or sleep and wakefulness.
Cambridge, Massachusetts - One of the main reasons for limiting the operating lifetimes of nuclear reactors is that metals exposed to the strong radiation environment near the reactor core become porous and brittle, which can lead to cracking and failure. Now, a team of researchers at MIT and elsewhere has found that, at least in some reactors, adding a tiny quantity of carbon nanotubes to the metal can dramatically slow this breakdown process.
Cambridge, Massachusetts - For many years, researchers tried to teach other kinds of animals some human language. Chimps, dolphins, gorillas - it didn’t seem to matter which animals they tried. Few experiments were regarded as success stories.
Cambridge, Massachusetts - DNA is made from four nucleosides, each known by its own letter - A, G, C, and T. However, since the structure of DNA was deciphered in 1953, scientists have discovered several other variants that are often added to the DNA sequences to replace one of the usual four letters.
