NEW YORK, Jan. 3, 2012 (Reuters) — With mounting evidence linking hundreds of small earthquakes from Oklahoma to Ohio to the energy industry's growing use of fracking technology, scientists say there is one way to minimize risks of even minor temblors. Only, it costs about $10 million a pop. A thorough seismic survey to assess tracts of rock below where oil and gas drilling fluid is disposed of could help detect quake prone areas. But that would be far more costly than the traditional method of drilling a bore hole, which takes a limited sample of a rock formation but gives no hint of faults lines or plates. The more expensive method will be a hard sell as long as irrefutable ...

A Universe Designed for Life (Chapter 10 of "Human Devolution - A Vedic Alternative To Darwin's Theory" by Michael Cremo)

A Universe Designed for Life The universe itself appears designed for life. Certain fundamental constants of nature, certain ratios between the forces of nature, appear to be very finely tuned. If their numerical values were even slightly different, the universe as we know it would not exist. Stable atoms, stars, and galaxies could not form (Barrow and Tipler 1996, p. 20). And thus, life itself, as we know it, could not exist.The values of the constants and ratios appear to be entirely arbitrary. In other words, as far as scientists today can tell, the values are not determined by any law of nature or property of matter. It is as if the values had been set by chance. But the odds ...

To mark his 70th birthday, physicist Professor Stephen Hawking answered a selection of questions from listeners to Radio 4's Today Programme. Topics ranged from the origins of the universe to the prospects for extra terrestrial life and the impact on Einstein's theory of relativity should neutrinos be confirmed to travel faster than light. Cannot play media. You do not have the correct version of the flash player. Download the correct version It seems clear that Professor Hawking believes we we will have to colonise space if we are to avoid catastrophe, but he is upbeat about the prospects for self-sustaining colonies on Mars and believes the human race will eventually spread out ...
Top ten tech predictions for 2012 … and how to interpret them
Post Date: 2012-01-05 06:41:49 by Tatarewicz

Around this time of year you see plenty of articles (such as this one) reflecting on notable technologies and events of the year now gone. Such pieces will also attempt to predict the events of the year just started. When reading these articles, it’s worth considering how the technologies being described are never taken in isolation. Instead, these technologies always need to be seen in terms of how they interact with and impact our personal and social lives. How technology does this, however, can be subtle and extremely complex. In fact, there is a significant amount of research – past and present – that focuses on why we do or don’t use software and technology. Most ...
Shot of Young Stem Cells Makes Rapidly Aging Mice Live Much Longer and Healthier, Researchers Report

ScienceDaily (Jan. 3, 2012) — Mice bred to age too quickly seemed to have sipped from the fountain of youth after scientists at the University of Pittsburgh School of Medicine injected them with stem cell-like progenitor cells derived from the muscle of young, healthy animals. Instead of becoming infirm and dying early as untreated mice did, animals that got the stem/progenitor cells improved their health and lived two to three times longer than expected, according to findings published in the Jan. 3 edition of Nature Communications. Previous research has revealed stem cell dysfunction, such as poor replication and differentiation, in a variety of tissues in old age, but it's not ...
Fly parasite turns honeybees into zom-bees

Some bees leaving their hives, then dying after wandering about in a stupor If deadly viruses and fungi weren't enough, honeybees in North America now must also deal with a fly parasite that causes them to leave their hive and die after wandering about in a zombie-like stupor, a new study shows. Scientists previously found that the parasitic fly, Apocephalus borealis, infects and ultimately kills bumblebees and paper wasps, while the "decapitating fly," an insect in the same genus, implants its eggs in ants, whose heads then pop off after the fly larvae devour the ants' brains and dissolve their connective tissues. Now researchers have discovered honeybees parasitized ...

Japan developing cyber weapon: report Japan has been developing a virus that could track down the source of a cyber attack and neutralise its programme, the daily Yomiuri Shimbun reported Sunday. The weapon is the culmination of a 179 million yen ($2.3 million) three-year project entrusted by the government to technology maker Fujitsu Ltd to develop a virus and equipment to monitor and analyse attacks, the daily said. The United States and China are reported to have put so-called cyber weapons into practical use, Yomiuri said. Japan will have to make legal amendments to use a cyber weapon as it could violate the country's law against the manufacture of a computer virus, the daily said. ...

Electric Eel vs Alligator: High-Voltage Showdown in Brazil A fisherman in Brazil was reeling in a surprise catch... an electric eel. However, another hunter also had (sic) an eye on the eel: an alligator (Actually, it looks more like a caiman, but moving right along). The alligator (or caiman) bites the electric eel, and the electric eel demonstrates why it's called an "electric eel".

We may never have to worry about running out of oil. I know that sounds crazy. It's the opposite of everything you've ever seen or heard. But I'm telling you now, it's true. And the reason why could make a few investors extremely wealthy. Yes, worldwide, we're thirsty for crude. And yes, it's all running out. What's more, what's left is either trapped in a war zone or in a dying well. At least that's the message you get from the news. But can I tell you what nobody else is talking about these days? See, there's an upside to every crisis. And the crisis over desperate oil demand and high oil prices is no different. How so? For one thing, the most ...

A tech expert has figured out a way that hackers could take control of mobile phones and make calls or send out unlimited numbers of text messages. Karsten Nohl, who runs Security Research Labs in Germany, told the Reuters news agency that while hackers have been able to stage such attacks on a small scale, he believes multiple phones powered by GSM technology could be compromised at the same time. “We can do it to hundreds of thousands of phones in a short time frame,” he told Reuters. Roughly 80 percent of world mobile phone users, including practically everyone in Germany, use GSM networks. Mass attacks against phones in the networks could be particularly insidious because ...
Sony uses shredded paper as a bio-battery power source

At the moment, the rechargeable batteries we rely on in our gadgets don’t contain the most environmentally-friendly materials, and aren’t the type of thing anyone should be throwing away. They should be recycled at a specialist recycle center. What would be much more eco-friendly is a way to create power from waste products, but at a level where an individual could do it themselves. Sony has been working to create these so-called bio-batteries, and has just shown one off at the Eco-Products 2011 environmental products fair in Tokyo. Sony’s idea is to provide a battery where by the user adds their own fuel sourced from waste materials. In this case, the proof of concept ...

Bugs may be resistant to genetically modified corn By RICK CALLAHAN, AP One of the nation's most widely planted crops — a genetically engineered corn plant that makes its own insecticide — may be losing its effectiveness because a major pest appears to be developing resistance more quickly than scientists expected. The U.S. food supply is not in any immediate danger because the problem remains isolated. But scientists fear potentially risky farming practices could be blunting the hybrid's sophisticated weaponry. When it was introduced in 2003, so-called Bt corn seemed like the answer to farmers' dreams: It would allow growers to bring in bountiful harvests using ...
ASU cosmologist suggests studying moon for alien artifacts

(PhysOrg.com) -- If you were part of a team sent to explore an unknown planet; and that planet had a natural orbiting moon, wouldn’t it make sense to use that moon as a base camp or remote observation post? Especially if you didn’t want those being observed to know you were there? Professor Paul Davis and research technician Robert Wagner think so, and that’s why they’ve published a paper in Acta Astronautica that suggests we humans begin taking a little closer look at our own moon to see if any alien life forms might have left behind some evidence of their visit. Though some might see it as farfetched, or heaven forbid, lunacy, Davis and Wagner are convinced that ...

Human beings are not creatures of facts and logic - they are people who live in stories. This is not new - it has always been that way. We have certain collective narratives that almost everyone automatically accept without further thought. It is how we make sense of the world. These narratives keep us sane by allowing us to filter out the hurricane of information swirling around us daily and making some sense of it. The current narrative that most people subscribe to is that economic growth will eventually return or we have plenty of oil but the government is not letting is drill for it. For that reason I am not convinced that you will ever convince the average citizen (not a technical ...
Neuroscientists identify a master controller of memory
Post Date: 2011-12-26 02:02:08 by Tatarewicz
1 Comments
One gene appears to regulate the brain’s ability to form new memories. When you experience a new event, your brain encodes a memory of it by altering the connections between neurons. This requires turning on many genes in those neurons. Now, MIT neuroscientists have identified what may be a master gene that controls this complex process. The findings, described in the Dec. 23 issue of Science, not only reveal some of the molecular underpinnings of memory formation — they may also help neuroscientists pinpoint the exact locations of memories in the brain. The research team, led by Yingxi Lin, a member of the McGovern Institute for Brain Research at MIT, focused on the Npas4 ...

Mark Kragh explains how to make a solar-powered mobile phone charger In a north London suburban street there is an unassuming wooden door which leads into a garage-cum-workshop which at first glance is remarkable only for a drum kit at one end. A second glance reveals a bunch of solar panels stacked against the wall and a man, busy breaking them up and reassembling them in a very home-made fashion. The end result is DIY solar kits that can recharge phones and batteries. They look makeshift but they have the potential to make a huge difference to people thousands of miles away in Kenya. As the director of KnowYourPlanet, Mark Kragh's day job is to resell solar panels to small ...

A vaccine that could deal a serious blow to seven in ten lethal cancers has been developed by scientists. In tests, it shrunk breast tumours by 80 per cent, and researchers believe it could also tackle prostate, pancreatic, bowel and ovarian cancers. Even tumours that resist treatment with the best medicines on the market, including the ‘wonder drug’ Herceptin, may be susceptible to the vaccine. Vaccine: A new drug could help fight 70 per cent of all cancers The experiments done so far have been on mice, but researchers hope to pilot the drug on people within two years. If all goes well, the vaccine – one of the first to combat cancer – could be on the market by 2020 ...

For the first time, researchers have been able to hack into the process of learning in the brain, using induced brain patterns to create a learned behavior. It’s not quite as advanced as an instant kung-fu download, and it’s not as sleek as cognitive inception, but it’s still an important finding that could lead to new teaching and rehabilitation techniques. Future therapies could decode the brain activity patterns of an athlete or a musician, and use them as a benchmark for teaching another person a new activity, according to the researchers. Scientists from Boston University and ATR Computational Neuroscience Laboratories in Kyoto used functional magnetic resonance ...
