In a new study, neuroscientists connected a network of electrodes to the hearing centers of 15 patients' brains (image above) and recorded the brain activity while they listened to words like "jazz" or "Waldo." They saw that each word generated its own unique pattern in the brain. So they developed two different computer programs that could reconstruct the words a patient heard just by analyzing his or her brain activity.

Abstract: The structure of the control network of transnational corporations affects global market competition and financial stability. So far, only small national samples were studied and there was no appropriate methodology to assess control globally. We present the first investigation of the architecture of the international ownership network, along with the computation of the control held by each global player. We find that transnational corporations form a giant bow-tie structure and that a large portion of control flows to a small tightly-knit core of financial institutions. This core can be seen as an economic "super-entity" that raises new important issues both for researchers and policy makers.
Policy makers would be much better placed to combat the effects of global warming if scientists had access to accurate measurements of the Earth's radiation balance from a dedicated satellite, claims an international group of physicists.
it estimates that the satellite could cut a decade or more from the time needed to make useful projections of global temperature at the end of the 21st century.

The Copenhagen group discovered that the redshifts agreed with the predictions of both general relativity and f(R) gravity, the theory that tries to avoid dark energy. However, the error bars on the redshifts excluded MOND and TeVeS, the theories that try to avoid dark matter.
