'Climategate' Panel Set To Report

From The BBC:

The second of three reviews into hacked climate e-mails from the University of East Anglia (UEA) is set to be released later.

It has examined scientific papers published over 20 years by the Climatic Research Unit (CRU) at the heart of the e-mail controversy.

The panel was nominated by the Royal Society, and climate sceptics forecast it would defend establishment science.

But the BBC understands the panel has taken a hard look at CRU methodology.

From The Independent:

It is 40 years since the drama of the Apollo 13 mission turned an aborted mission to the moon from potential disaster into a celebrated recovery.

But doubts still linger about the moon landings. 9/11 and Kennedy aside, no event in world history has generated quite so many conspiracy theories than the Apollo moon landings. Do they stand up? Here are the best reasons why it couldn’t have happened, and the rebuttals. Of course, you may disagree.

New Force Behind Agency of Wonder -- New York Times

ARLINGTON, Va. — The Defense Advanced Research Projects Agency is different from other federal agencies. For one thing, the agency, known as Darpa, created the Internet (really). For another, it is probably the only agency ever to offer a $40,000 prize for a balloon hunt, a contest that was inspired by Regina Dugan, a 47-year-old expert in mine detection, who took over last summer as its director.

Dr. Dugan, who has a Ph.D. in mechanical engineering from the California Institute of Technology, is the first woman to be the director of Darpa, and those who know her say she has a knack for inspiring, and indeed insisting on, creative thinking.

A currently ongoing ransomware campaign is using a novel approach to extort money from end users whose PCs have been locked down.

By pretending to be the fake ICPP Foundation (icpp-online.com), the ransomware locks down the user’s desktop issuing a “Copyright violation: copyrighted content detected” message, which lists torrent files found on the infected PC, and forces the user to pay $400 for the copyright holder’s fine, emphasizing on the fact that “the maximum penalties can be five years in prison and up to $250,000 in fines.

Does Stress Feed Cancer?

From Scientific American:


A new study shows stress hormones make it easier for malignant tumors to grow and spread.

A little stress can do us good—it pushes us to compete and innovate. But chronic stress can increase the risk of diseases such as depression, heart disease and even cancer. Studies have shown that stress might promote cancer indirectly by weakening the immune system's anti-tumor defense or by encouraging new tumor-feeding blood vessels to form. But a new study published April 12 in The Journal of Clinical Investigation shows that stress hormones, such as adrenaline, can directly support tumor growth and spread.

Turning Planetary Theory Upside Down: Nine New Exoplanets Found, Some With Retrograde Orbits

Exoplanets, discovered by WASP together with ESO telescopes, that unexpectedly have been found to have retrograde orbits are shown here. In all cases the star is shown to scale, with its rotation axis pointing up and with realistic colours. The exoplanets are shown during the transit of their parent star, just before mid-transit. The last object at the lower right is for comparison and has a “normal” orbital direction. The size of each image is three solar diameters. (Credit: ESO/A. C. Cameron)

From Time Magazine:

Disciplining young children is one of the key jobs of any parent — most people would have no trouble agreeing with that. But whether or not that discipline should include spanking or other forms of corporal punishment is a far trickier issue.

The American Academy of Pediatrics (AAP) does not endorse spanking for any reason, citing its lack of long-term effectiveness as a behavior-changing tactic. Instead the AAP supports strategies such as time-outs when children misbehave, which focus on getting kids to reflect on their behavior and the consequences of their actions. Still, as many parents can attest, few responses bring about the immediate interruption of a full-blown tantrum like a swift whack to the bottom.

He lived in a community where numbers were venerated as much for their spiritual qualities as for their mathematical ones. His elevation of numbers as the essence of the world made him the towering primogenitor of Greek mathematics, essentially the beginning of mathematics as we know it now.

Better Military Technology Does Not Lead to Shorter Wars, Analysis Reveals


From Science Daily:

ScienceDaily (Mar. 31, 2010) — It is generally assumed that military technology that is offensive rather than defensive in nature leads to shorter wars. Yet, a new doctoral thesis from the University of Gothenburg, Sweden, shows that this assumption is not correct.

For long, researchers have thought that offensive military technology, such as armoured cars and attack jets, makes it easier to shorten the duration of a war. It is also generally perceived that when the offensive technology is more effective than the defensive technology, it is more advantageous to start a war.

From Live Science:

Everyone grumbles when prices at the pump rise, but some drivers pay more depending on where they live. A new study shows how gas price spikes hurt the wallets of drivers in some states more than in others.

On average, Mississippi drivers spent more than 6 percent of their annual income on gas in 2009, compared to drivers in Connecticut and New York who spent just 2.5 percent of their income on gas. But a price spike similar to the one in July 2008 would have worsened the imbalance — Mississippi drivers would have seen driving costs shoot up to 11 percent as opposed to just 4.3 percent for Connecticut and New York.

Oceanology: Tethered Antenna Keeps Subs In Touch

There's a sub below (Image: Brooke Ocean Technology)

From New Scientist:

ROBOTIC submarines have always had trouble when it comes to picking up GPS signals and communicating with their operators. That's because radio signals do not travel far underwater. If the submarines do not surface regularly in order to check their position, they run the risk of drifting off-course.

This problem could now be solved, thanks to a wing-like antenna that piggybacks on small submarines. The antenna ascends to the surface on a tether as and when needed, enabling satellite communications, including GPS readings. It can even carry a camera to serve as a kind of periscope for the sub's controller.
