Some exiting news

ABDOMINAL surgery is a radical way of losing weight, but could it also cure type 2 diabetes?



Duodenal exclusion is a form of gastric bypass surgery in which the upper small intestine or duodenum is removed, so that the stomach feeds directly into the mid-small intestine. This reduces the amount of time the body has to absorb calories from food, meaning people lose weight.

Surgeons performing duodenal exclusions on obese people with diabetes had noticed that in around 98 per cent of cases the patients' diabetes spontaneously vanished a few weeks after surgery - too soon to be accounted for by weight loss.

Plant genes switched on by sound waves Premium



CAN plants hear? They all respond to light, which affects how they optimise growth and survival. Plants also have a sense of touch, allowing them to stiffen in response to wind, and a "taste" for nutrients. But whether they respond to sound is a mystery.

Now Mi-Jeong Jeong of the National Institute of Agricultural Biotechnology in Suwon, South Korea, and colleagues claim to have identified two genes in rice that respond to sound waves. They also say that the promoter of one of the sound-sensitive genes could be attached to other genes to make them respond to sound too.

The findings follow a host of similar, but unsubstantiated, claims that plants respond to sound. If the researchers are correct, they say their discovery could enable farmers to switch specific crop genes on and off, such as ones for flowering, by blasting sound into the fields. That might be cheaper than pesticide and healthier.

My comment: Little by little, we learn that our environment is much more alive than we thought. Maybe this will finally lead to some respect for the Nature and learning how to use it, without abusing it.

Out-of-body experiences are 'all in the mind'
Movie Camera



By deliberately scrambling a person's visual and tactile senses, it is now possible to give them an "out-of-body" experience.

Two procedures – which are the first to imitate an out-of-body experience artificially – use cameras to fool people into thinking they are standing or sitting somewhere else in a room. They provide the strongest proof yet that people only imagine floating out of their bodies during surgery or near-death experiences.


His conclusion is that our perception of self within the body is tightly bound to how our brains process information from our senses. "I'm not interested in out-of-body experiences," says Ehrrson. "I'm interested in why I, as myself, am located in my body – why we have 'in-body' experiences, if you like."

He says the work is important because it de-stigmatises reports of out-of-body experiences by people who are on drugs, or ill with conditions such as migraine or epilepsy. "They don't have to be mad to experience these things," he says.


My comment: Well, I don't believe Astral Projection or Lucid Dreams are all in the mind, if you ask me the experiments merely prove brain process out-of-the-body sensations/meaning it process the experiences and translates them to our senses and vice versa/ or that it can be stimulated artificially to feel them. Of course it's the brain that produces them, that's our processor after all-everything we do or feel passes trough it and it's done by it, no one argued on that! But who stimulates them is other question. I believe our soul is the producer in our mind's theater.


Anyway,the great thing about this news is that it can be used for creating 3D virtual reality, like the one from the movies-you put something on your head and you're somewhere else. Cool, right?
