image: A noninvasive method for measuring brain blood flow with light has been developed by biomedical engineers and neurologists at UC Davis, and used to detect brain activation. The new method, ...

Optogenetics is increasingly used to map brain activation using techniques that rely on functional hyperaemia, such as opto-fMRI. Here we test whether light stimulation protocols similar to those ...

It typically takes some dramatic chemistry to turn light hydrocarbons like methane and propane into molecules that can be used as something other than fuel. Making them into one useful class of ...

A new non-invasive method for measuring brain blood flow with light performs similarly to functional magnetic resonance imaging but at less cost. This is the claim of biomedical engineers and ...

Researchers at the University of Tsukuba investigated whether monoamine neurotransmitters, such as dopamine, are involved in hippocampal activation even during light exercise. Dopamine secreted from ...

Scientists use a broadband light source to manipulate fluid flow in millimetre-sized channels, a process that could help to speed up mixing in microfluidic networks. Researchers at the Hungarian ...

Chemokines 'trigger' the integrin LFA-1 to different conformational and affinity states. Elegant experiments provide new insights into the involvement of different LFA-1 affinity states in rapid ...
