For the first time, a science experiment has measured Earth’s ability to absorb neutrinos — the smaller-than-an-atom particles that zoom throughout space and through us by the trillions every second at nearly the speed of light. The experiment was achieved with the IceCube detector, an array of 5,160 basketball-sized sensors frozen deep within a cubic kilometer of very clear ice near the South Pole.

New composite material made of carbon nanotubes

Due to their unique properties, carbon nanotubes would be ideal for numerous applications, but to date they cannot be combined adequately with other materials, or they lose their beneficial properties. Scientists have developed an alternative method of combining, so they retain their characteristic properties. As such, they ‘felt’ the thread-like tubes into a stable 3-D network.

Smart people have better connected brains

Differences in intelligence have so far mostly been attributed to differences in specific brain regions. However, are smart people’s brains also wired differently to those of less intelligent persons? A new study supports this assumption. In intelligent persons, certain brain regions are more strongly involved in the flow of information between brain regions, while other brain regions are less engaged.
