In the latest Swan's on Tea blog there is a link to a slighty spooky video of a cat being completely calmed (practically "deactivated" per the vid title) by a bulldog clip to the scruff of the neck with no discomfort or obvious side effects. Its quite a remarkable transformation for such a feisty and seemingly independent animal to be calmed, almost frozen, so entirely and in such an outwardly humane manner. Is this behaviour a throwback to the time as a kitten in which mother cat carries kittens in her mouth (and the young cannot wriggle too much) or is there something deeper? There is no chance that such reversion to infantile automatic behaviour exists in hum…

http://www.dedicatedpain.com/spider.jpg The piece of wood it is on is a 2x4. Any thoughts? EDIT: I found this, maybe it. http://en.wikipedia.org/wiki/Huntsman_spider

for a short story i'm writing; what would happen if someone's finger was submerged in -25 degrees C liquid? would it freeze enough to smash it or would it just kill it or what?

the magnesium ion is taken up into the cell via the magnesium/ATPase pathway, if we wanted to get magnesium into the cell another route, if we bound magnesium to an amino acid, would it be possible to get the magnesium and amino acid compound to go through the amino acid pathway?

Hello everybody. I am new here. I am not in science field, i have no scientific knowledge at all. So my questions are for getting more knowledge and not to be ironice or to pretend to be a smart person. Well, my question is the classical black race intelligent question. I do not care about what white people say, i do not care about what black people say. I care only about what scientists say. Of course, i know that black people do not have the same opportunities to success. Whites are more possible to access higher knowledge. Furthermore, success does not always goes with high IQ. The only thing i want to know is about the cold scientific liable results. …

Hello. I want informations such as how it is being built up by the host cell, how it is commanded to enter into certain operational states, how it is partitioned on cell divison, so that both of the dauther cells will get some of them. Mainly, i want to verify a claim wich i read at sens.org (you can also, watch videos by Aubrey de Gray). They say, that one important thing bound to the aging process is the mutation of genes in the mitochondrion (in certain cells i assume) during the lifespan of an individual. These are allegedly mainly (big) deleterious mutations, leading to the mal/disfunction of mitochondrion, causing harm or death to the host cell. That if true, wo…

i have noticed that in movies and anime people are always able to dash at incredible speed and they doge to amazing distances then i got curious how fast can human go without machines ?

What is the experience of listening at the nanoscale? A Live performance‐installation by Joel Ong John Curtin Gallery on Sunday 10th July 2011 Gallery open: 4:30‐7:00pm Nanovibrancy explores nanoscale activity through sound by amplifying the oscillations at the surface of a model tympanic membrane in real time. The culmination of his Masters in Biological Art degree, Joel Ong will present a sound piece which repurposes the Atomic Force Microscope as a super‐sensitive listening device. The AFM listens by scanning the surface vibrations on a silk membrane. The sample, currently researched in otology as a graft material for chronic ear…

The common opinion on sleep is that it's unconsciousness but I did some research and read that you can dream in all 5 stages, and when you don't dream you ruminate, also that you do some "conscious" actions such as movement, sleepwalking, talking in sleep, etc. Does that mean that a level of consciousness still exists? Like you don't remember everything during sleep but if you did remember everything would it be more of a memory of being extremely drowsy or complete unconsciousness (like in anaesthesia)? Or would it simply be a memory of being there (like when you wake up from anaesthesia it feels like you just opened your eyes after closing them but after sleep it's n…

My company is going to buy cell lines for developing antibodies(including 70 kinds of antibody). If you have good cell lines, please contact us, WLTHNU@163.COM. Also we can cooperate

When an animal or plant dies, its dead body rots and smells bad. Humans get rid of the bad smell by burying the corpses. What happens to the corpse of a bacterium when it dies? There are so many bacteria on humans. And the bacteria have such short lives. They must be dying all the time, and leaving trillions of corpses all over us. Where do the bacterial corpses go, do they just fall off us, or do they stay stuck on? Can they be smelled?

I'm looking for some kind of resource (book/video/website/etc.) that will give me pictures of both animal and plant cells at different magnifications, and their sizes (in micrometers). Any tips? I've Googled but can't find much.

Here is a video about abiogenesis I found, I'm not sure how accurate it is. It does seem to be plausible but I am not familiar with this idea, it is new or old or more wild speculations?

"Does zinc affect the symptoms of the common cold?" Only high quality studies were included wherein people were given zinc or a placebo, but neither they nor the scientists knew which until afterwards. The results of all the studies were combined, so, without doing any new experiments, we can aim for the best possible knowledge about whether something works or not. In this case, the results for just under a thousand otherwise healthy patients were used. http://www.interesti...mmon-cold-zinc/ Would you take zinc to improve recovery from the Common Cold?

I've always had this ability to see specs of light, and decided I would look up what I'm actually seeing. Unfortunately though none of what I experience is described in my search. I've seen information on floaters, "seeing stars", and even the idea that they are just small protiens. But I don't think this fully covers what I see. They don't affect my vision at all, it doesn't require light for me to see them (even when its pitch black I can see the little lights and I'm not sure if this is normal), they also aren't everywhere, by which I mean sometimes I can pretty much see them all the time, but occasionally I don't. In certain instances they become much brighter (this i…

I was curious as to how much Tums Antacids slow down the average human metabolism. They act to neutralize the acids of the stomach, so it seems that some slack in process would occur. Thanks!

Our nervous system causes us to feel physical things. If it weren't for our nerves, our bodies would be numb like novocaine; case in point, paraplegics. But, what causes us to feel emotion? Like, if it weren't for this organ, we would probably be Vulcans.

In 1938 fishermen caught a live coelacanth off the coast of South Africa, even though up until that time it had been believed that these creatures had been extinct since the late Cretacean Period. Given the huge amount of hidden space under the oceans of the world, it seems possible that a sufficiently large breeding population of cryptozoological creatures might continue to exist for eons without our knowing it. But on land the possibility of strange creatures being discovered seems much less likely, since we should already have seen strange creatures by now, given that they would have to be supported by a large breeding population for them to survive. This is part…

I had this thought one day; Every living thing on earth besides plants needs plants to survive. So would it not be safe to say plants are critical to the evolution of all living things that are not photosynthetic?

How did all the fossils we find on earth formed. Is it not possible to be the remains of a silica based lifeform that exist in the past. How is it possible for a tree trunk or dead animal to lie for hundreds of years in the water in such a way that it dont get destroyed. How can silica that are so insolloble get inside a tree trunk with a diamitar of owerone metre and replace the wood(carbon) layer by layer

How can I select the cell lines from numerously cell lines? Our company want to develop antibody and buy cell lines. If you are a knowledgable person , please give helps. we could cooperate on it. My email is WLTHNU@163.COM.

Can a bulb planted in the ground ( eg tulip ) move up or down in the soil in order to establish its optimum growing conditions?

I tried doing some google searches and read a few articles as well as doing a search here, but I have not found any info on why marine dinosaurs went extinct. It seems rather odd if it was a meteor impact that it would cause extinction of some fish and not others. Is there any explanation as to why bony fish, sharks and a few other marine animals made it through but marine dinosaurs and other types of marine monsters that existed back then did not?

First- I've considerably less expertise on this subject than I'm going to attempt to portray. My theory here is that the current boom of aspbergers on the baby market is an epigenetic reaction to the overstimulation of the information age. From what I have gathered, the environmental conditions one's forebearers experienced can determine which genes will be expressed further down the timeline. A previous period of famine might encourage a generation of people that produce fat more readily as long term energy storage or what have you. So perhaps the comparitive level of stimuli in these last few generations has the species scrambling to keep up however it can. Instead of a…
