Nice article from the Times of India, citing research using Yoga Asanas: Among the many clinical researches being conducted at Nimhans , one involved patients of an old-age home who were exposed to six months of yoga therapy. MRI scans taken before and after showed an increase in the size of the hippocampus, the brain’s memory index. “It waslarger than before because the grey matter had increased. The results will be published in a scientific journal shortly ,” adds Gangadhar. The hippocampus is vulnerable to stress and atrophy is seen in patients of schizophrenia, post-traumatic stress disorder (PTSD) and severe depression. “Yoga acts as an antidepressant ,” he says.

I read this article a few years ago and it keeps popping up. From the SMU News, Southern Methodist University in Dallas Texas, USA.
DALLAS (SMUNews) — Researchers from Southern Methodist University have described two seismic events that they believe may offer the first evidence of a previously undetected form of matter passing through the earth.
This form of matter — known as “strange quark matter” — is so dense that a ton-sized nugget would be about the size of a red blood cell. Physicists have suspected since 1984 that this very heavy form of matter might exist, but no one has yet found evidence of it.
In 1984, Harvard physicist and Nobel Laureate Sheldon L. Glashow suggested that one way such matter might be found would be if a physicist teamed up with a seismologist to search for traces of the matter that might have passed through the earth at supersonic speed. In 1993, SMU physicist Vidgor Teplitz asked Eugene Herrin, a seismologist in the Department of Geological Sciences in SMU’s Dedman College, to collaborate with him on the project. The two were assisted by David Anderson, a senior systems analyst in the Department of Geological Sciences, and Ileana Tibuleac, then a Ph.D. student in the Department of Geological Sciences.
In a paper submitted to the Bulletin of the Seismological Society of America and published online at http://xxx.lanl.gov/ (subject area: astrophysics), the SMU researchers describe how they found evidence of strange quark matter by searching through more than a million records of seismic events collected by the U.S. Geological Survey from 1990 to 1993 that were not associated with traditional seismic events such as earthquakes. These records of so-called “unassociated events” were collected from seismic stations set up around the world to monitor earthquakes and nuclear testing.
In a paper previously published in 1995 (available online at http://cornell.mirror.aps.org/abstract/PRD/v53/i12/p6762_1), Herrin and Teplitz had determined that it would be feasible to search for seismic events that might indicate passage of strange quark matter (also known as nuclearites) through the earth because such events would have a distinct seismic signal — a straight line. This would be caused by the large ratio of speed to the speed of sound in the earth. Herrin estimates that strange quark matter might pass through the earth at 250 miles per second, 40 times the speed of seismic waves. The team also determined that the minimum requirement for detection of a nuclearite would be detection of its signal by seven monitoring stations.
In their new paper, the SMU researchers describe two seismic events with the linear pattern they were looking for. One event occurred on Oct. 22, 1993, when something entered the Earth off Antarctica and left it south of India .73 of a second later. The other occurred on Nov. 24, 1993, when an object entered south of Australia and exited the Earth near Antarctica .15 of a second later. The first event was recorded at seven monitoring stations in India, Australia, Bolivia and Turkey, and the second event was recorded at nine monitoring stations in Australia and Bolivia.
“We can’t prove that this was strange quark matter, but that is the only explanation that has been offered so far,” Herrin said.
The SMU team is now trying to determine where the heavy quark matter may have come from. In April 2002, two different teams of scientists reported that they had identified collapsed stars that might be composed of ultradense strange quark matter. Scientists believe that chunks of strange quark matter might be created when stars made of strange quark matter collide.
Unfortunately, Herrin notes, seismologists may not be able to find any more events that suggest the passage of strange quark matter through the Earth. In 1993 the U.S. Geological Survey stopped collecting data from “unassociated events” such as those that the SMU team used in its research.

A presentation at the United Nations North Lawn building presented statistics gathered by the Stockholm International Peace Research Institute (SIPRI) about spending on armaments and militarism. The report declared that in 2013 over 1,747 billion dollars were spent on armaments. SIPRI Director Sam Perlo Freeman pointed out that the overwhelming majority of military spending was being done by the US and its allies.
While military spending by the United States has slightly decreased, spending by strategic US aligned regimes around the world is dramatically rising. Kingdom of Saudi Arabia, which is a key US ally in the Middle East and a backer of insurgent groups in Syria, has increased its military spending by 14.8%, the largest increase of any country on earth. John Feffer of Institute for Policy Studies, one of the presenters, told Press TV, that the build-up of military spending by US aligned regimes around the world has dangerous implications and could lead to war. Presenters pointed out that military spending is rising most rapidly in the Middle East and the Pacific, and that despite recent cuts, the United States remains the main exporter of weapons and supplier of military aid.

The sailing stones of the Racetrack Playa, a dry lakebed in Death Valley, have been the subject of a mystery since the 1940s. The playa is dotted with stones, some as large as 700 pounds (320kg), with long tracks behind them, as though they have been performing a synchronised dance.
Although there have been many theories about how the rocks might be moving on their own — including dust devils, hurricane-force winds, films of slippery algae or thick sheets of ice — none had ever been confirmed, nor had any human seen the rocks actually moving.
Until now, that is. A team of researchers from the Scripps Institution of Oceanography at UC San Diego decided they were going to solve the mystery once and for all. In the winter of 2011, they brought in a high-resolution weather station to measure wind at one-second intervals, and brought in 15 rocks fitted with GPS devices (since the National Parks Service would not allow them to use the native rocks).
