Bibek Paudel brings us a BBC report on the development and testing of an new ion engine by a security firm named Qinetiq. The engine will be used in an ESA spacecraft tasked with mapping the Earth’s gravitational field from orbit. Only a handful of ion drives have been used for space missions before, some of which we have discussed. Quoting: “Cryogenic pumps can be heard in the background, whistling away like tiny steam engines. Using helium gas as a coolant, they can bring down the temperature in the vacuum chamber to an incredibly chilly 20 Kelvin (-253C). The pressure, meanwhile, can drop to a millionth of an atmosphere. Ion engines … make use of the fact that a current flowing across a magnetic field creates an electric field directed sideways to the current. This is used to accelerate a beam of ions (charged atoms) of xenon away from the spacecraft, thereby providing thrust.”

An anonymous reader writes “The USENIX LEET workshop held earlier this week in San Francisco offered neat insights into the Storm botnet, including two papers showing the difficulty of accurately measuring the botnet’s size, and one on the way it conducts its spamming campaigns (down to the template language used). There was a bunch of other cool work too, so check out the papers.”

RemyBR writes “Researchers at Osaka University are stepping up efforts to develop robotic body parts controlled by thought, by placing electrode sheets directly on the surface of the brain. The research marks Japan’s first foray into invasive (i.e. requiring open-skull surgery) brain-machine interface research on human test subjects. The aim of the research is to develop real-time mind-controlled robotic limbs for the disabled. ‘To date, the researchers have worked with four test subjects to record brain wave activity generated as they move their arms, elbows and fingers. Working with Advanced Telecommunications Research Institute International (ATR), the researchers have developed a method for analyzing the brain waves to determine the subject’s intended activity to an accuracy of greater than 80%.’”

bibekpaudel writes “ScienceDaily reports that a wealth of papers belonging to Charles Darwin have been published on the web, some for the first time. Some 20,000 items and 90,000 images were posted today to http://darwin-online.org.uk/. The new site is the largest collection of Darwin’s work in history, according to organizers from Cambridge University Library ‘This release makes his private papers, mountains of notes, experiments, and research behind his world-changing publications available to the world for free,’ said John van Wyhe, director of the project. The collection includes thousands of notes and drafts of his scientific writings, notes from the voyage of the Beagle when he began to formulate his controversial theory of evolution, and his first recorded doubts about the permanence of species.”

Smivs writes “European scientists say that growing plants on the moon should be possible. Scientists in the Netherlands believe growing plants on our sister satellite would be useful as a tool to learn how life adapts to lunar conditions. It would also aid in understanding the challenges that might be faced by manned bases. ‘The new step, taken in the experiments reported at the EGU, is to remove the need for bringing nutrients and soil from Earth. A team led by Natasha Kozyrovska and Iryna Zaetz from the National Academy of Sciences in Kiev planted marigolds in crushed anorthosite, a type of rock found on Earth which is very similar to much of the lunar surface. In neat anorthosite, the plants fared very badly. But adding different types of bacteria made them thrive; the bacteria appeared to draw elements from the rock that the plants needed, such as potassium.’”

Gasoline prices have continued their charge up to $4 a gallon this day, rising to a new record high of $3.418 after jumping 1.9 cents last night.

Gas prices have been rising sharply over the past few months in reaction to record high oil prices and a weak dollar, and some analysts are already predicting that we will be seeing $4 a gallon before it is all stated and done. Diesel prices also rose to a new high, hitting $4.146 per gallon.

As we noted in earlier discussions, gas prices are only expected to move higher in the next few months as more drivers hit the road for their summer vacations. The heavy demand summer driving months always apply upward pressure to prices, and despite the current high prices, summer demand will definitely push prices even higher.

Right now we’ve several factors working against us. The first, is the upcoming heavy demand summer months as we have already discussed. In global news, we hear that Russia is producing less oil this year, the first time in a decade that this has been the case. China is also in the news this week, announcing that diesel oil imports last month jumped 49%. Iran has spooked some investors with tough speak about wiping Israel off the map if provoked.

Back at home, we continually hear about the falling dollar. As the dollar has been in a literal free fall, all commodities have been moving higher. Consequently, oil is rising, and pushing gasoline higher. If you’re hoping that the dollar is going to rebound soon, don’t bet the farm on that assumption. Analysts are predicting that America is going to be cutting its interest rates at least one, possibly even two more times this year. As you know, lower rates lead to a weak dollar. This will lead to higher oil, and yes… higher gasoline.

With oil analysts predicting that oil is going to be headed up towards $125 this summer, it is definitely feasible that the national average of gasoline will indeed hit $4 this summer. Depending on where you live, $4 gas might already be a reality. California readers know what I am talking about.

Will the current high prices lead to less demand this summer? That’s the question that everyone is asking themselves, and something that we will definitely be hearing more about in the months to come.

For those of you out there that don’t want to cut back on your daily routine, but are looking for ways to reduce your driving costs, one of the best things you can do, is just simply drive slower. It is estimated every additional 10 mph you drive over 60 mph is equivalent to adding 54 cents per gallon to your bill. So perhaps the ideal thing we have the ability to do is just slow down a bit, and take our time. It could put a lot more money back into your pocket!

How about your driving habits? Have you been reducing your daily routine to help fight the current gasoline prices, or going on business as usual and just accepting the current prices? What driving tips would you have for our fellow readers to help keep driving costs down to a minimum?

caterpillar logoEarnings are to be reported Friday, April 18 by Caterpillar Inc. (NYSE: CAT). Any analyst concerns about the company’s current earnings are focused upon the weakened construction trade and flagging demand for large trucks. However, analysts site the company’s large and strong global footprint, along with capital advantages stemming from the depressed dollar, to buttress predictions that company earnings shall keep in step with the previous two quarters. Company sentiment is generally positive overall.

Analysts first quarter profit estimates for Caterpillar range mainly between 1.33 and 1.49 per share on revenue of $10.77 billion. These numbers would be in keeping with results from Q4 2007. The company seems to be holding up extraordinarily well under current economic conditions. Analysts forward outlook for Caterpillar seems positive yet guarded.

The Associated Press sites the thought of Andrew Casey, analyst for Wachovia (NYSE: WB). He indicates that Caterpillar is improving the margin on it’s engines business. Casey is quoted as stating “This should be a positive short-term catalyst for stock price action.”

I believe that steel and fuel prices have put a bit of extra drag on Caterpillar’s earnings for the first quarter. I’ll say my earnings prediction to be within a penny of 1.40, give or take.

mytrip writes “Senator Joe Biden (D-Del) has proposed an ambitious plan, costing on the order of $1 billion, aimed at curtailing illegal activities via P2P networks. His plan involves utilizing new software to monitor peer-to-peer traffic on an ongoing basis. ‘At an afternoon Senate Judiciary subcommittee hearing about child exploitation on the World wide web, Sen. Joe Biden (D-Del.) stated he was under the impression it’s “pretty simple to pick out the person engaged in either transmitting or downloading violent scenes of rape, molestation” simply by looking at file names. He urged use of those techniques by investigators to help nab the most egregious offenders.”

Foobar of Borg writes “AP is reporting that the US will soon be collecting the DNA of anyone who is arrested by federal law enforcement bureau and any foreigner who is detained, whether or not charges are eventually brought. This begins to bring the US in like with the UK which, as discussed before on slashdot, is trying to collect DNA of ‘potential criminals’ as young as five. DHS spokesman Russ Knocke said that “DNA is a proven law-enforcement tool.””

sm62704 writes “I found this New Scientist article interesting, as I was actually alive (albeit very small) when Bikini Atoll was H-bombed. The article states that the reason the reefs are now flourishing is because they are mostly undisturbed by humans, who are afraid of the radiation. Background levels there are now ’similar to that at any Australian city,’ while nearby islands haven’t been so lucky.’When I put the Geiger counter near a coconut, which accumulates radioactive material from the soil, it went berserk,’ states Maria Beger of the University of Queensland in Australia.”
