Ian Stevenson - Reincarnation Research

Dr. Ian Stevenson's Reincarnation Research 
By Kevin Williams

Ian Stevenson (1918-2007) was a psychiatrist who worked for the University of Virginia School of Medicine for 50 years. He was Chair of the Department of Psychiatry from 1957 to 1967, the Carlson Professor of Psychiatry from 1967 to 2001, and a Research Professor of Psychiatry from 2002 until his death.

He was also the founder and Director of the University of Virginia's Division of Perceptual Studies investigating parapsychological phenomena such as (1)  reincarnation, (2) near-death experiences, (3) out-of-body experiences, (4) after-death communications, (5) deathbed visions, (6) altered states of consciousness and psi. His researches were made possible by an estate left by an entrepreneur for investigating specially these areas.

He did rigorous research. He found evidence suggesting that memories and physical injuries can be transferred from one lifetime to another. He traveled extensively over a period of 40 years, investigating 3,000 cases of children around the world who recalled having past lives. His meticulous research presented evidence that such children had unusual abilities, illnesses, phobias and philias which could not be explained by the environment or heredity.

Evidence against Socio-Psychological Hypothesis

Contrary to expectation, B and A cases of India and Sri Lanka all yielded
approximately equal percentages of correct statements and the average overall number
of statements was lower for the A cases. These findings suggest that the sociopsychological
process of "creating" more, and more correct, statements after the families
meet does not take place or at least does not influence the data to a measurable degree.
The very fact that B cases exist indicates that a meeting between families is not a
necessary condition for the occurrence of CORT. Because the data appear not to confirm
the essential predictions derived from the socio-psychological hypothesis, this hypothesis
seems unable to explain CORT.
Conclusion
No evidence was obtained to support the hypothesis that socio-psychological
circumstances promote a false elaboration of apparent memories of previous lives.

Alcohol also causes Cancer - Seven types of cancer




In a review  in the journal Addiction, Jennie Connor, from the University of Otago in New Zealand, pointed out that  alcohol is responsible for  cancer of the mouth and throat, larynx, oesophagus, liver, colon, bowel and breast.


She said alcohol is estimated to be the reason for 5.8 per cent of cancer deaths worldwide. Heavy drinking increases risk, but even people who drink at low levels are at risk.

Image processing has traditionally been studied as a form of signal processing, and a subfield of electrical engineering. Recently, with the advent of inexpensive and integrated image capturing devices, leading to massive data and novel applications, the field has seen tremendous growth. Within computational mathematics, image processing has emerged not only as an application domain where computational mathematics provide ideas and solutions, but also in spurring new research directions (a “new Computational Fluid Dynamics”) in geometry (Total Variation regularization and Level Set methods), optimization (primal-dual, Bregman and Augmented Lagrangian methods, L1 convexification), inverse problems (inpainting, compressive sensing), and graph algorithms (high-dimensional data analysis). This talk gives an overview of these developments.

Novel canonical transformation provides insights into many-particle physics
Date: February 16, 2016

The concepts of rotation and angular momentum play a crucial role in many areas of physics, ranging from nuclear spectroscopy to molecular collisions and precision measurements. In a new paper, researchers introduce a technique to understand and calculate angular momentum in settings where many particles interact with each other, so-called many-particle systems.

Pesticides in Food We Eat

Proc Natl Acad Sci U S A. 1990 Oct; 87(19): 7777–7781.

Dietary pesticides (99.99% all natural).
B N Ames, M Profet, and L S Gold

Abstract

The toxicological significance of exposures to synthetic chemicals in food is examined in relation to the exposures to naturally occurring chemicals in foods. The authors found that 99.99% (by weight) of the pesticides in the American diet are chemicals that plants produce to defend themselves. 52 natural pesticides have been tested in high-dose animal cancer tests, and about half (27) are found to be rodent carcinogens. These 27 pesticides are present in many common foods. The authors conclude that both natural and synthetic chemicals are equally likely to be variables causing cancer  in animals. The authors also conclude that at the low doses of most human exposures the comparative hazards of synthetic pesticide residues are insignificant.

How the Brain Makes Complex Decisions - Mathematical Model

6 Feb 2016

The mathematical model, developed by researchers from the University of Cambridge, is the first biologically realistic account of the process, and is able to predict not only behaviour, but also neural activity. The results are reported in The Journal of Neuroscience.
