Habits form when brainwaves slow down

Habits form when brainwaves slow down

Habits may be difficult to change, but now at least we have an insight into how they form. When a group of neurons fire simultaneously, the activity appears as a brainwave. Different brainwave-frequencies are linked to different tasks in the brain. To track how brainwaves change during learning, Ann Graybiel and Mark Howe at the […]

Faster-than-light neutrino claim bolstered

Faster-than-light neutrino claim bolstered

Representatives from the OPERA collaboration spoke in a seminar at CERN today, supporting their astonishing claim that neutrinos can travel faster than the speed of light. The result is conceptually simple: neutrinos travelling from a particle accelerator at CERN in Switzerland arrived 60 nanoseconds too early at a detector in the Gran Sasso cavern in […]

The Sustainable City

As the urbanisation of the planet intensifies and natural resources diminish, the way we build is increasingly being questioned. City planners, architects, and engineers are all looking for innovative solutions for the way we design cities, create a public space or private house as well as for the building materials themselves. Focusing on landmark buildings, […]

Self-directed microspider could repair blood vessels

Self-directed microspider could repair blood vessels

A new spider-like micromachine could swim through a person’s blood vessels, healing damaged areas and delivering drugs as it goes. Ayusman Sen of Pennsylvania State University in University Park and his colleagues have created the self-propelling microspiders using spheres less than a micrometre wide. Each sphere is made up of two halves – one hemisphere […]
