[J Physiol Paris. 2012. Tutkimus: Ruokavalion muutos keikauttaa suoliston mikrobit päivässä - Tiede. Suoliston mikrobit reagoivat ruokavalion muutokseen paljon nopeammin kuin tähän asti on oletettu. Tuoreessa tutkimuksessa pelkälle liha- tai kasvisruokavaliolle laitettujen ihmisten suolistomikrobien voimasuhteet keikahtivat yhdessä yössä. Harvardin yliopiston tutkimus sai inspiraationsa havainnoista, joiden mukaan ruokavalion muutos näkyy hiirten suolistomikrobistossa hyvin nopeasti.
He halusivat testata, onko muutos ihmisillä yhtä nopea. Asiasta ei tätä ennen ole tehty luotettavia selvityksiä. Tutkijat rekrytoivat kokeeseen kymmenen vapaaehtoista, jotka jaettiin kahteen ryhmään. Ensimmäinen sai syödä viiden päivän ajan vain lihaa, munaa ja maitotuotteita, kun taas toisen ruokavalio sai sisältää vain täysjyväviljaa, hedelmiä ja kasviksia. Eräs vapaaehtoisista oli noudattanut vegetaristista ruokavaliota useita vuosia, mutta suostui koemielessä liharyhmään. Kaikilta vapaaehtoisilta otettiin joka päivä ulostenäyte, josta määritettiin sen sisältämät mikrobit sekä niiden geeniaktiivisuus.

Singer, Princeton University, Princeton, NJ, October 6, 2004 (received for review August 26, 2004) Abstract Practitioners understand “meditation,” or mental training, to be a process of familiarization with one's own mental life leading to long-lasting changes in cognition and emotion.
Little is known about this process and its impact on the brain. Little is known about the process of meditation and its impact on the brain (1, 2). Methods The subjects were eight long-term Buddhist practitioners (mean age, 49 ± 15 years) and 10 healthy student volunteers (mean age, 21 ± 1.5 years). We first collected an initial electroencephalogram (EEG) baseline consisting of four 60-s blocks of ongoing activity with a balanced random ordering of eyes open or closed for each block.

Scientists Discover a Jewel at the Heart of Quantum Physics - Wired Science. Physicists reported this week the discovery of a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality.
“This is completely new and very much simpler than anything that has been done before,” said Andrew Hodges, a mathematical physicist at Oxford University who has been following the work. The revelation that particle interactions, the most basic events in nature, may be consequences of geometry significantly advances a decades-long effort to reformulate quantum field theory, the body of laws describing elementary particles and their interactions. Interactions that were previously calculated with mathematical formulas thousands of terms long can now be described by computing the volume of the corresponding jewel-like “amplituhedron,” which yields an equivalent one-term expression. The amplituhedron itself does not describe gravity.
