MIT chemists designed a new type of pencil lead consisting of carbon nanotubes, allowing them to draw carbon nanotube sensors onto sheets of paper.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a totally unexpected spiral structure in the material around the old star R Sculptoris. This is the first time that such a structure, along with an outer spherical shell, has been found around a red giant star. It is also the first time that astronomers could get full three-dimensional information about such a spiral. The strange shape was probably created by a hidden companion star orbiting the red giant.

Among the advantages of the reactor, mention can be made of the fact that no sludge is produced during the purification process.

This illustration depicts a single molecular-sized pore in a graphene membrane. The membrane is separating carbon dioxide from nitrogen. A carbon dioxide molecule is passing through the pore while nitrogen molecules are too large to pass through.

The world's needs for energy and raw materials are constantly growing, and the search for readily accessible and inexpensive material for energy applications is driving research teams all around the world. Fuel cells based on hydrogen and oxygen, for example, can convert stored chemical energy into electrical energy in an environmentally friendly way, as the byproduct is simply water.

Fenitrothion is an insecticide and anti-rodent material which is widely used in farms and fields.

The system integrates circuit level components including imec's active electrodes and EEG amplifier together with a microcontroller and a low power radio. It is capable of continuously recording 8 channel EEG signals while concurrently recording electrode-tissue contact impedance (ETI).

Britain has launched a multi-million-dollar global initiative to help fight organized criminals and terrorists using the Internet. The plan was rolled out at an international gathering in Budapest aimed at making the Internet more secure.
