A Russian scientist says that a video of the surface of Venus from a Soviet probe sent there in 1982 shows evidence of a scorpion-like creature, along with other objects that he believes are evidence of life. However, NASA scientists say the objects in question are more likely video distortions and a lens cap.

Leonid Ksanfomaliti works for the Space Research Institute of the Russian Academy of Sciences, and recently published his detailed analysis of video taken by the Russian Venus-13 probe. His article in the Russian Solar System Research (Astronomicheskii Vestnik) magazine points out three objects he says were constantly moving. Besides the "scorpion", Ksanfomaliti pointed out a disk shaped object and a black patch.

The idea of life on Venus is not given much credence by most mainstream scientists because of the extreme surface temperatures, which can exceed 800 degrees Fahrenheit.

UK: This Raspberry Pi Sure Tastes Good!

The first 10,000 Raspberry Pis will be coming off the assembly line in the next few weeks. What's a Raspberry Pi, you ask?

It's a little $25 single-board computer that's about as powerful as a typical smartphone. The project is the brainchild of Eben Upton of Cambridge University who co-founded the Raspberry Pi Foundation. The foundation is a registered charity in the U.K.

While the first batch of Raspberry Pis are expected to be snatched up by hackers, computer geeks and electronics hobbyists, the ultimate aim of the project is to get these cheap little computers into the hands of schoolkids.

Most primary and secondary school computer education consists of learning how to use Microsoft Office and other proprietary software programs. Kids are being taught how to be users rather than creators of software.

One commentator on BBC Radio Four's Material World program likened the current computer curriculum in the U.K. as being similar to the high school typing classes of old. My sense is that it's not much different in Canada.

The hope is that through the Raspberry Pi, students will once again start learning about how computers work and how to program. I say "again" because when I think back to my high school computer training back in the punch card days of the 1970s, I was learning the rudimentary basics of programming. While I never became a programmer, what I learned back then helped me for the rest of my life.

The low cost of the Raspberry Pi means that parents won't have to worry about their children "breaking" the family computer by experimenting.

ThePirateBay.org yesterday announced via its blog, first reported by GigaOM, that users can now search in a new category called "Physibles".

Physibles, as the blog explains, are mock-up files that allow a 3D printer to create a physical object:
"We believe that the next step in copying will be made from digital form into physical form. It will be physical objects. Or, as we decided to call them: Physibles.

Data objects that are able (and feasible) to become physical. We believe that things like three-dimensional printers, scanners and such are just the first step. We believe that in the nearby future, you will print your spare parts for your vehicles," The Pirate Bay predicted in its post yesterday.

Best of the Web: Biofuels pollute more than oil, leaked data show

Greenhouse gas emissions from biofuels such as palm oil, soybean and rapeseed are higher than those for fossil fuels when the effects of Indirect Land Use Change (ILUC) are counted, according to leaked EU data seen by EurActiv.

The default values assigned to the biofuels compare to those from Canada's oil sands - also known as tar sands - according to the figures, which should be released along with long-awaited legislative proposals on biofuels in the spring.

A spokesperson for the European Commission said she could "not comment on leaked documents, such as impact assessments which have not been published."

But industry and civil society sources described the data as credible and in line with other studies. One said it would sound a death knell for the biodiesel industry, if published.

"I think the science has proved clearly that because of the link to deforestation in places such as South East Asia, a lot of the biodiesels have significantly negative impacts on the climate," Robbie Blake, a spokesman for Friends of the Earth, told EurActiv.

Comment: So the net effect is that the 'green measures' put into place to 'save the planet' will cost us more and speed up destruction of the planet.

Previously elusive 'cold plasma' low-energy ions now found to be abundant in Earth's surrounding space

Washington, DC - Cold plasma has been well-hidden. Space physicists have long lacked clues to how much of this electrically charged gas exists tens of thousands of miles above Earth and how the stuff may impact our planet's interaction with the sun. Now, a new method developed by Swedish researchers makes cold plasma measurable and reveals significantly more cold, charged ions in Earth's upper altitudes than previously imagined.

At these lofty elevations, storms of high-energy charged particles - space weather - roil the atmosphere, creating auroras, buffeting satellites, and sometimes wreaking havoc with electronic devices and electric grids on Earth. The new evidence of abundant cold (i.e. low-energy) ions may change our understanding of this tumultuous space weather and lead to more accurate forecasting of it, scientists say. The finding might also shed light on what's happening around other planets and moons - for instance, helping explain why the once robust atmosphere of Mars is so wispy today.

Brain's 'Cheat Sheet' Makes Moral Decisions Easier

© Alita Bobrov, ShutterstockThe brain's "rule book" keeps us from having to weigh the pros and cons of unthinkable moral decisions.

How much would someone have to pay you to switch from drinking coffee every morning to drinking tea? How about to rescind the almost-universal belief that murder is wrong and then kill an innocent person?

Most likely, your brain processed those two questions in very different ways, a new study finds. People weigh questions of sacred values - such as "don't murder" - in different brain regions than they do mundane preferences. These special brain regions seem to be those associated with recalling rules, suggesting that we don't weigh the costs and benefits when asked to do something against our most firmly held values. Instead, we fall back on a mental "cheat sheet" of right and wrong.

"If you had to do cost-benefit calculations for everything you do in your daily life, you wouldn't be able to come to any decisions at all," said study researcher Gregory Berns, director of the Center for Neuropolicy at Emory University. "So rules actually have the benefit of making decision-making much easier ... you just look up in your own personal 'rule table' how to act."

Paramount is selling UltraViolet movies without forcing a hard copy purchase, but comes with strict limitations.

Following news that Amazon will sell codes for UltraViolet movies without forcing consumers to purchase physical discs, Paramount Pictures will be the first studio to offer digital movie purchases directly from its website. What does this mean for consumers? A movie or TV episode that can be played across multiple devices, not just one specific hardware set or operating system.

Or maybe not. The purpose of UltraViolet is to offer consumers one digital copy that can be accessed on Android and iOS mobile devices, desktops, notebooks, Blu-ray players and other compatible devices. Introduced in October 2011, select Blu-ray movies like The Smurfs and Green Lantern contained a code that essentially "unlocked" the digital version via UltraViolet. Consumers simply needed to create an UltraViolet account, enter the code, and bam! There's your movie in a virtual locker.

Geothermal Test Will Pour Water into Volcano to Make Power

Geothermal energy developers plan to pump 24 million gallons of water into the side of a dormant volcano in central Oregon this summer to demonstrate technology they hope will give a boost to a green energy sector that has yet to live up to its promise.

They hope the water comes back to the surface fast enough and hot enough to create cheap, clean electricity that isn't dependent on sunny skies or stiff breezes - without shaking the earth and rattling the nerves of nearby residents.

Renewable energy has been held back by cheap natural gas, weak demand for power and lack of political concern over global warming. Efforts to use the earth's heat to generate power, known as geothermal energy, have been further hampered by technical problems and worries that tapping it can cause earthquakes.

Even so, the federal government, Google and other investors are interested enough to bet $43 million on the Oregon project.

They are helping AltaRock Energy of Seattle and Davenport Newberry Holdings of Stamford, Conn., demonstrate whether the next level in geothermal power development can work on the flanks of Newberry Volcano, about 20 miles south of Bend, Ore.

Is The Air Force's X-37B Space Plane Spying On A Chinese Satellite?

The X-37B
© BoeingThe X-37B is shown here after landing at 1:16 a.m. Pacific time on December 3, 2010, concluding its more than 220-day experimental test mission. It was launched from Cape Canaveral Air Force Station, Fla., on April 22, 2010.
The U.S. Air Force's classified X-37B space plane should have returned to Earth in December.

But the top-secret unmanned spacecraft continues to glide along its unusually low orbit nearly one year after it was launched in March 2011, leading Spaceflight magazine to suggest the vehicle is spying on a Chinese spacelab called Tiangong-1, the BBC reports.

The X-37B, also known as the Orbital Test Vehicle (OTV), is a 29-foot solar-powered craft NASA has been developing since 1999. In that time, the vehicle has been launched twice, including the most recent mission from which it has yet to return.

According to the Air Force, the craft's purpose is to test "reusable spacecraft technologies for America's future in space and operating experiments which can be returned to, and examined, on Earth."

Since the Air Force took over operations of the shuttle in 2006, the Pentagon has remained mute on the program's overall budget and plans, compelling amateur astronomers to keep an eye on its movements, The New York Times reported in May of 2010. They noticed the shuttle orbited over "global trouble spots" like Iraq, Iran, Pakistan, and North Korea.

Science Rewrites Assumptions About Pre-Historic Animals

University of Alberta technician Clive Coy sometimes spends a year or more cleaning up newly-uncovered fossils.
Paleontologist Phil Currie was walking along the sandstone cliffs of the badlands in southern Alberta when he spotted something sticking out of the side of the hill.

It appeared to be the fossil of an ancient turtle. But as he began to clear away the sand, he could see that it was the skull of a dinosaur.

There is nothing extraordinary about finding fossils in Dinosaur Provincial Park. In fact, there is no better place to find the remains of these so-called "terrible lizards" that walked the earth for more than 165 million years.

But in the days that followed in that summer of 2010, Currie suspected he may have found something extraordinary indeed. This specimen appeared to be so rare and so exquisitely preserved that he instructed his students and colleagues to go slow with the excavation when he had to leave base camp for a few days.

"I just didn't want to miss out on this one," he recalls. "It's extremely rare to find a dinosaur such as this, and almost as rare to find one that is so complete. I wanted to be there to see what we had by the time we were done with it."

Currie likes to say that building a dinosaur from fossils found in sand or embedded in rock is both an art and a science. Having a skull and a nearly complete skeleton such as this one, which he plans to reveal to the public in a year or two, makes it relatively simple.
