Yes it looks like the next technology advancement than the old crude radio waves but how can it carry more information ?

Ontario pays its neighbors to take its surplus power. Battery technology is in its infancy. Considering the waste, I would have thought this would be a huge priority. Why is this technology difficult to achieve?

"Earth's oldest fossils have been found in Australia by a team from the University of Western Australia and Oxford University. The microscopic fossils show convincing evidence for cells and bacteria living in an oxygen-free world over 3.4 billion years ago. The team, led by Dr David Wacey of the University of Western Australia and including Professor Martin Brasier of Oxford University, report the finding in the journal Nature Geoscience. 'At last we have good solid evidence for life over 3.4 billion years ago. It confirms there were bacteria at this time, living without oxygen,' says Professor Brasier of the Department of Earth Sciences at Oxford." http://www…

Following the failure of a wide range of attempts to solve the crystal structure of M-PMV retroviral protease by molecular replacement, we challenged players of the protein folding game Foldit to produce accurate models of the protein. Remarkably, Foldit players were able to generate models of sufficient quality for successful molecular replacement and subsequent structure determination. The refined structure provides new insights for the design of antiretroviral drugs. http://www.nature.com/nsmb/journal/vaop/ncurrent/full/nsmb.2119.html I don't kwon who are the game players though.

Earth's Atmosphere May Be More Efficient at Releasing Energy to Space Than Climate Models Indicate, Satellite Data Suggest ScienceDaily (July 29, 2011) — Data from NASA's Terra satellite suggests that when the climate warms, Earth's atmosphere is apparently more efficient at releasing energy to space than models used to forecast climate change may indicate. http://www.sciencedaily.com/releases/2011/07/110729031754.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Ftop_news%2Ftop_environment+%28ScienceDaily%3A+Top+News+--+Top+Environment%29

I need help figuring out how to safely handle a bottle of nitric acid that has white crystals on the cap. I know that it is Ammonium Nitrate, which is explosive. How concerned should I be with this? I was told that a single spark could set it off. I am afraid to open the cabinet that it is in or to pick up the bottle. I want to dispose of this but am not sure how to handle it to do so. In other words, I don't want to blow my arm or any other body parts off. Can anyone help me out?

Mother Tongue and Y Chromosomes Some 6000 different languages are spoken in the world today, and tracing the prehistory of languages and of language change by means of genetic markers has long been a goal (1). However, this has proven to be a more challenging task than simply tracing colonizations. Nevertheless, a number of genetic studies over the past few years have started to address language and language change before recorded history. A correlation is emerging that suggests language change in an already-populated region may require a minimum proportion of immigrant males, as reflected in Y-chromosome DNA types. By contrast, the female lineages, as indicated by mi…

Hiya folks, my name is Ash and I am new to this forum. I found this forum by typing in the words: "genetic manipulation" into google. I am a newly qualified Pharmacist and have recently thinking about the fact that conventional medicine controls symptoms and is not curative as such. I am looking to get into the field of genetics. Any advice any1? Any geneticists about to advise? I am from the Midlands in UK. Regards

Astronauts on the International Space Station (ISS) got another eyeful of Hurricane Irene's increasing might today (Aug. 25) as their space capsule streaked over the monstrous Category 3 storm, which is barreling toward U.S. shores. Ahead of the flyover, ISS video cameras revealed placid views of wispy white clouds scattered over the blue of the ocean. Then a huge mass of white appeared on the horizon: Hurricane Irene, a powerful debut storm for the 2011 Atlantic hurricane season. Even from 220 miles (350 kilometers) above the Earth, the storm's power was on full view.

New research by scientists in the Department of Biology at the University of York shows that species have responded to climate change up to three times faster than previously appreciated. These results are published in the latest issue of the leading scientific journal Science. Faster distribution changes. Species have moved towards the poles (further north in the northern hemisphere, to locations where conditions are cooler) at three times the rate previously accepted in the scientific literature, and they have moved to cooler, higher altitudes at twice the rate previously realised. Analysing data for over 2000 responses by animal and plant species, the research …

My news to you is great; all the world is watching CERN or Tevatron to find Higgs boson by the end of 2012 or in 3 years from now, but imagine that a person comes and tell you " I found Higgs boson ", it is unbelievable but it's true. We all know that Higgs boson is in Nature and we have just to find it and this is what I did. Please visit my blog for more information

My Chemistry teacher told me that screening effect is the ability of the atom to prevent the valence electrons from being pulled towards the nucleus. The screening effect depends only on the number of electron orbits inside the valence shell. For instance, the atoms crossways Period 3 have 3 shells occupied by electrons. So, the screening effect remains unchanged. But I thought that when going across Period 3 from left to right, the number of electrons increases and so does the electrostatic force. This causes the valence shells to be pulled closer to the nucleus. So, my opinion is, the ability of the atoms to prevent the valence shells from being pulled towards the n…

Watching TV for an average of six hours a day could shorten the viewer's life expectancy by almost five years, indicates research published online in the British Journal of Sports Medicine. The impact rivals that of other well known behavioural risk factors, such as smoking and lack of exercise, the study suggests. Sedentary behaviour -- as distinct from too little exercise -- is associated with a higher risk of death, particularly from heart attack or stroke. Watching TV accounts for a substantial amount of sedentary activity, but its impact on life expectancy has not been assessed, say the authors. They used previously published data on the relationship betw…

It’s true, the loudest animal in the world (relatively speaking), as described by BBC News ‘Singing penis’ sets noise record for water insect, is a fresh water insect (Micronecta scholtzi) that plays “music” by rubbing its penis on its abdomen. This music reaches levels up to 99.7 decibels. Relating this to a sounds we may all understand, that is equivalent to a listening to a very loud orchestra or music act from the front row. It should also be noted that this tiny bug, in the grand scheme of things is not much quieter than much larger animals such as blue whales. The reason these little bugs don’t completely cause our heads to cave in, is because they li…

http://www.scientificamerican.com/article.cfm?id=genetically-modified-crop I saw these researchers speak at the ESA meeting. Meredith Schafer (the Masters student) stated that 86% of canola sampled in transects (away from farmers fields) contained transgenes that allow the plant to resist herbicides glyphosate and/or glufosinate. Farmers are seeing these feral transgenic canola plants growing in fields in which canola has not been planted. So Monsanto, since it's YOUR genes that have escaped, are you going to be responsible for the extra cost to farmers caused by weedy pesticide-resistant canola growing in their fields? mmmm probably not.

The farther that human populations live from the equator, the bigger their brains, according to a new study by Oxford University. But it turns out that this is not because they are smarter, but because they need bigger vision areas in the brain to cope with the low light levels experienced at high latitudes. Scientists have found that people living in countries with dull, grey, cloudy skies and long winters have evolved bigger eyes and brains so they can visually process what they see, reports the journal Biology Letters. The researchers measured the eye socket and brain volumes of 55 skulls, dating from the 1800s, from museum collections. The skulls represented 1…
