Some papers say that meditation can have beneficial health effects, and that makes sense, but a new paper claiming evidence of specific molecular changes in the body following a period of mindfulness meditation is likely the first of its kind.

The scholars investigated the effects of a day of intensive mindfulness practice in a group of experienced meditators, compared to a group of untrained control subjects who engaged in quiet non-meditative activities. After eight hours of mindfulness practice, the meditators showed a range of genetic and molecular differences, including altered levels of gene-regulating machinery and reduced levels of pro-inflammatory genes, which in turn correlated with faster physical recovery from a stressful situation. 

Peer-reviewed articles are taking off on Twitter - whether or not people have read them is another story.

But someone read them during peer review so more exposure is good even if, in the case of legacy journals, people can only read the abstract.

Visit a museum these days and you'll see people using their smartphones and cameras to take pictures of works of art, archeological finds, historical artifacts, and every other object and most of them will never be looked at again. Even worse, while taking a picture might seem like a good way to preserve the moment, new research suggests the opposite actually happens.

In a new paper, psychologist Linda Henkel of Fairfield University presents data showing that participants had worse memory for objects, and for specific object details, when they took photos of them.

Experiments with ultrashort laser pulses support the idea that quantum interactions between molecules help plants, algae, and some bacteria efficiently gather light to fuel their growth - but that's about it. Key details of nature's vital light-harvesting mechanisms remain obscure, and the exact role that quantum physics may play in understanding them is more subtle than was once thought.

Overworked patent offices are struggling to keep up with the rapid explosion in information and technology that genetic sequences represent. An international project may have a solution - a free and open public resource that will bring transparency to the murky and contentious world of gene patenting.

"Apparently, many patent offices have no way of tracking genetic sequences disclosed in patents and currently do not provide them in machine-searchable format," said principal author Professor Osmat Jefferson, a Queensland University of Technology academic who leads an international team analysing biological patents for the open-access web resource, The Lens.
