www.guardian.co.uk/enviro...-renewable-energy-storage Giant gravel batteries could make renewable energy more reliable Wind and solar power are often criticised for being too intermittent, but Cambridge researchers could change that offshore wind power An offshore windfarm near Prestatyn, north Wales. Photograph: Christopher Thomond Newly designed giant gravel batteries could be the solution to the on-off nature of wind turbines and solar panels. By storing energy when the wind stops blowing or the sun stops shining, it is hoped the new technology will boost to renewable energy and blunt a persistent criticism of the technology - that the power from it is intermittent.

A robot capable of deceit has been developed by American military researchers. A new program enables a robot to detect whether another robot is susceptible to lies, and to use its gullibility against it by telling lies, researchers claim. The robot could be capable of deceiving humans in a similar way, according to the scientists, based at the Georgia Institute of Technology. * People are suspicious of foreigners because they do not trust their accents, research claims The breakthrough could lead to military advances through the development of robots which can disarm bombs and carry wounded servicemen from danger. Its understanding of the concept of deception would enable the robot ...

In Asheville, N.C., Anthony Brenner holds a handful of industrial hemp shiv, left, and a block of the finished hardened product after the shiv is mixed with hydraulic lime. He designed a home with thick hemp walls that was completed this summer and is currently working on another one that will use hemp on interior walls. Hemp is turning a new leaf. The plant fiber, used to make the sails that took Christopher Columbus' ships to the New World, is now a building material. The hemp home was built for $133 per square foot, not including land and excavation costs, at the top of a mountain. In Asheville, N.C., a home built with thick hemp walls was completed this summer and two more are ...

Hundreds of self-described Tea Party activists took to the streets of Lower Manhattan Wednesday, and they weren't protesting the planned mosque and cultural center near Ground Zero. These activists are opposed to northeastern states' efforts to limit greenhouse gas emissions that contribute to climate change. Nancy Cagliostro came into Manhattan from her home in Holmdel, New Jersey in a bus rented by the conservative group Americans for Prosperity. Cagliostro believes there's an alliance between environmentalists and Wall Street to make bankers rich through a secretive auction to limit carbon dioxide emissions. "It's the Goldman Sachses and the Morgan Stanleys all ...

Thorium One ton of thorium can produce as much energy as 200 tons of uranium and 3.5 million tons of coal, according to the former director of CERN. via Telegraph An abundant metal with vast energy potential could quickly wean the world off oil, if only Western political leaders would muster the will to do it, a UK newspaper says today. The Telegraph makes the case for thorium reactors as the key to a fossil-fuel-free world within five years, and puts the ball firmly in President Barack Obama's court. Thorium, named for the Norse god of thunder, is much more abundant than uranium and has 200 times that metal's energy potential. Thorium is also a more efficient fuel source -- ...

Why our agricultural empire will fall

An expert tells us how our food system is repeating the history of doomed civilizations In an age of super-sized meals and obesity epidemics, food-shortage doomsday scenarios always seem a little surreal. Backed by half a century of agricultural abundance, it's easy to imagine that cheap food will permanently abound. But in a new book, "Empires of Food," academic Evan Fraser and journalist Andrew Rimas show us that we are not the first advanced civilization to have a hubristic, misplaced confidence that we'll always be fed. By tracing the rise and fall of a number of preindustrial empires, the authors show us just how much trouble we're in. The Romans, the ...

New Chromosome Research Undermines Human-Chimp Similarity Claims.by Jeffrey Tomkins, Ph.D., & Brian Thomas, M.S. A recent high-profile article in the journal Nature released the results of a study with implications that shocked the scientific community because they contradict long-held claims of human-chimp DNA similarity.A previous Acts & Facts article showed that much of the research surrounding the often touted claims of 98 percent (or higher) DNA similarity between chimps and humans has been based on flawed and biased research.The problem is that the similarity has been uncertain because no one has performed an unbiased and comprehensive DNA similarity study until now. And the ...
'Minority Report' moves from reel into real life

LONDON: In a chilling scenario that reminds you of Steven Spielberg's sci-fi thriller "Minority Report", law enforcers in the US will be relying on a software to predict who will commit crimes. The software may even be able to tell where, when and how the crime will be committed, just as it happened in the 2002 movie. The programme collates a range of variables then uses an algorithm to work out who is most certain to commit an offence, reports the Daily Mail. The software is likely to spark an outcry from civil rights groups over its unmistakable resemblance to the "Minority Report". In the movie, Tom Cruise heads a 'Precrime' unit which uses genetically ...
A Two-Tier Internet?

A Two-Tier Internet? The Internet as you know it is in serious, serious danger. Some of the most powerful communications companies in the world have been involved in negotiations and have been making agreements that would throw net neutrality out the window and would move us toward a two-tier Internet. So exactly what would that mean? It would mean that the big corporate giants that have a virtual monopoly on other forms of media and entertainment would be able to buy access to the blazing fast "next generation" Internet that communications companies are developing and the rest of us (like this site for example) would be stuck on the decaying "gravel roads" of the old ...
Massive solar storm to hit Earth in 2012 with 'force of 100m bombs'

Melbourne, Aug 26 (ANI): Astronomers are predicting that a massive solar storm, much bigger in potential than the one that caused spectacular light shows on Earth earlier this month, is to strike our planet in 2012 with a force of 100 million hydrogen bombs. Several US media outlets have reported that NASA was warning the massive flare this month was just a precursor to a massive solar storm building that had the potential to wipe out the entire planet's power grid. Despite its rebuttal, NASA's been watching out for this storm since 2006 and reports from the US this week claim the storms could hit on that most Hollywood of disaster dates - 2012. Similar storms back in 1859 and ...

The Sun is changing the rate of radioactive decay, and breaking the rules of chemistry

The Sun is changing the rate of radioactive decay, and breaking the rules of chemistry The Sun is changing the supposedly constant rates of decay of radioactive elements, and we have absolutely no idea why. But an entirely unknown particle could be behind it. Plus, this discovery could help us predict deadly solar flares. It's one of the most basic concepts in all of chemistry: Radioactive elements decay at a constant rate. If that weren't the case, carbon-14 dating wouldn't tell us anything reliable about the age of archaeological materials, and every chemotherapy treatment would be a gamble. It's such a fundamental assumption that scientists don't even bother ...

Having written for a decade that the Earth has been cooling, it was rather disconcerting to receive a news release from Accuweather reporting that “The year 2010 is on track to become the hottest year on record since modern record keeping began, according to climate researchers at the National Oceanographic and Atmospheric Administration (NOAA).” It turns out there is an explanation for the unusual levels of heat from Russia to Pakistan to Japan. It is a meteorological phenomenon called “blocking events” and they are related to the jet stream. An August 10 article by Michael Moore in New Scientist explained, “According to meteorologists monitoring the atmosphere ...
BP oil spill: scientists find giant plume of droplets 'missed' by official account

Scientists have mapped a 22-mile plume of oil droplets from BP's rogue well in the depths of the Gulf of Mexico, providing the strongest evidence yet of the fate of the crude that spewed into the sea for months. The report offers the most authoritative challenge to date to White House assertions that most of the 5m barrels of oil that spewed into the Gulf is gone. "These results indicate that efforts to book-keep where the oil went must now include this plume," said Christopher Reddy one of the members of the team from Woods Hole Oceanographic Institute. The report, which is published in the journal Science, also said the plume was very slow to break down by natural ...

Thousands of online banking customers have accounts emptied by 'most dangerous trojan virus ever created' By David Derbyshire Last updated at 7:25 PM on 11th August 2010 Cyber criminals have raided the accounts of thousands of British internet bank customers in one of the most sophisticated attacks of its kind. The fraudsters used a malicious computer programme that hides on home computers to steal confidential passwords and account details from at least 3,000 people. The internet security experts M86, who uncovered the scam, estimate that at least £675,000 has been illegally transferred from the UK in the last month - and that the attacks are still continuing.

Does the Past Exist Yet? Evidence Suggests Your Past Isn't Set in Stone

Recent discoveries require us to rethink our understanding of history. "The histories of the universe," said renowned physicist Stephen Hawking "depend on what is being measured, contrary to the usual idea that the universe has an objective observer-independent history." Is it possible we live and die in a world of illusions? Physics tells us that objects exist in a suspended state until observed, when they collapse in to just one outcome. Paradoxically, whether events happened in the past may not be determined until sometime in your future -- and may even depend on actions that you haven't taken yet. In 2002, scientists carried out an amazing experiment, which ...

"Doesn’t Life Require Compromise?" by Ayn Rand Current mood: determined A compromise is an adjustment of conflicting claims by mutual concessions. This means that both parties to a compromise have some valid claim and some value to offer each other. And this means that both parties agree upon some fundamental principle which serves as a base for their deal. It is only in regard to concretes or particulars, implementing a mutually accepted basic principle, that one may compromise. For instance, one may bargain with a buyer over the price one wants to receive for one's product, and agree on a sum somewhere between one's demand and his offer. The mutually accepted ...

MILWAUKEE (AP) - For students entering college this fall, e-mail is too slow, phones have never had cords and the computers they played with as kids are now in museums. The Class of 2014 thinks of Clint Eastwood more as a sensitive director than as Dirty Harry urging punks to "go ahead, make my day." Few incoming freshmen know how to write in cursive or have ever worn a wristwatch. These are among the 75 items on this year's Beloit College Mindset List. The compilation, released Tuesday, is assembled each year by two officials at this private school of about 1,400 students in Beloit, Wis. The list is meant to remind teachers that cultural references familiar to them might ...

By Tom Brown MIAMI | Tue Aug 17, 2010 8:27pm EDT MIAMI (Reuters) - Two new scientific reports raised fresh fears on Tuesday about the environmental fallout from the world's worst offshore oil spill and questioned government assurances that most of the oil from the ruptured well in the Gulf of Mexico was already gone. In one of the reports, researchers at the University of Georgia said about three-quarters of the oil from BP's blown-out Macondo well was still lurking below the surface of the Gulf and may pose a threat to the ecosystem. Charles Hopkinson, who helped lead the investigation, said up to 79 percent of the 4.1 million barrels of oil that gushed from the broken well ...

Lasers could make virtual particles real 19:55 17 August 2010 by David Shiga For similar stories, visit the Quantum World and The Large Hadron Collider Topic Guides Next-generation lasers will have the power to create matter by capturing ghostly particles that, according to quantum mechanics, permeate seemingly empty space. The uncertainty principle of quantum mechanics implies that space can never be truly empty. Instead, random fluctuations give birth to a seething cauldron of particles, such as electrons, and their antimatter counterparts, called positrons. These so-called "virtual particles" normally annihilate one another too quickly for us to notice them. But physicists ...
