USS Revenge Found After 200 Years
For two centuries it rested a mile from shore, shrouded by a treacherous reef from the pleasure boaters and beachgoers who haunt New England's southern coast.
Now, researchers from the US Navy are hoping to confirm what the men who discovered the wreck believe: that the sunken ship off the coast of Rhode Island is the USS Revenge, commanded by Oliver Hazard Perry and lost on a stormy January day in 1811.
"The Revenge was forgotten, it became a footnote," said Charlie Buffum, a brewery owner from Connecticut who found the shipwreck while diving with friend Craig Harger. "We are very confident this is it."

A New Approach To Fight Cancer
Out of control: biologists still cannot explain why cancerous cells will proliferate and spread to other organs if unchecked
The Final Frontier In The War On Cancer -- The Telegraph
Frustrated by glacial progress, the US has turned to physicists to fight the disease, reveals Paul Davies.
When President Nixon declared war on cancer 40 years ago, he also sanctioned one of the biggest research programmes in history. The budget of America’s National Cancer Institute (NCI) is now $5 billion a year, more than Nasa spends on space exploration. Cancer accounts for a large slice of research funds in most other developed countries, too: Cancer Research UK, for example, has a budget of £500 million a year.

What Oil Shortage?
The latest report from the Calgary (Alberta, Canada) Herald was nothing but good news: The steadily declining production of light oil from 2002 to late 2010 has reversed itself completely and is now not only proving the power and principles of a free market but “will change the way we think about oil, with many weighty consequences…” says blogger Peter Tertzakian. The graph he provided here shows Alberta’s production declining by about 16,000 barrels per day (B/d) every year since 2002, dropping to just over 300,000 B/d in late 2010. Now, thanks to new capital, new technology, and new enthusiasm, production is close to 400,000 B/d. It also “could heighten the blood pressure of a few peak oil theorists,” said Tertzakian.

How Many Humans Have Lived On This Planet?
Do The Dead Outnumber The Living? -- BBC
The population of the planet reached seven billion in October, according to the United Nations. But what's the figure for all those who have lived before us?
It is often said that there are more people alive today than have ever lived - and this "fact" has raised its head again since the UN announcement about the planet's population reaching a new high.
The idea helps fuel fears that the population is expanding too fast.
It is true that if you delve back into the mists of time, the population of Earth was tiny in comparison to today and logically it might seem plausible that the living outnumber the dead.

Pandora's Box Has Already Been Opened For Bio-Terrorists
Details Of Secret Experiments On Deadly Man-Made Bird Flu That Kills Over Half Of The People It Infects WILL Get Out, Says Bioterrorism Watchdog -- Daily Mail
* 'The infrastructure to stop a pandemic is not there,' says Professor Paul Keim
Details of secret experiments by scientists who have created the most deadly form of bird flu in the lab will inevitably be leaked - potentially into the hands of terrorists - an expert has warned.
A furore erupted in December over the decision by the U.S National Science Advisory Board for Biosecurity (NSABB) to censor details of the virus being made public, which can be transmitted by coughs and sneezes.
But now the head of that board claims they will enter the public domain anyway.

Is Facebook And Twitter Addictive?
A new study suggests that social networking services such as Facebook and Twitter are more difficult to resist than cigarettes or alcohol.
A team from the University of Chicago’s Booth School of Business recently conducted an experiment involving 205 people in Wurtzburg, Germany to analyze the addictive properties of social media and other vices.
Participants in the week-long study were polled via BlackBerry smartphones seven times per day and asked to report when they experienced a desire within the past 30 minutes, and whether or not the succumbed to that desire. They were also asked to gauge each desire on a scale from mild to “irresistible.”

The Climate Skeptics 'May' Be Right
From Climategate Central: The Skeptics Were Right -- Don Surber
The world is cooling. Finally, this admission comes from the British weather service (the Met Office) and the University of East Anglia’s Climatic Research Unit — the center of the Climategate Conspiracy in which some climatologists conspired to manipulate data in a mad effort to “prove” their daft theory that using carbon-based fuels would turn the planet into Hell On Earth.
They now must admit the truth that Global Warming is in error.
And so they do.

'Oldest Living Thing On Earth' Discovered
Scientists say a patch of ancient seagrass in the Mediterranean is up to 200,000 years old Photo: Getty Images
'Oldest Living Thing On Earth' Discovered -- The Telegraph
Ancient patches of a giant seagrass in the Mediterranean Sea are now considered the oldest living organism on Earth after scientists dated them as up to 200,000 years old.
Australian scientists sequenced the DNA of samples of the giant seagrass, Posidonia oceanic, from 40 underwater meadows in an area spanning more than 2,000 miles, from Spain to Cyprus.
The analysis, published in the journal PLos ONE, found the seagrass was between 12,000 and 200,000 years old and was most likely to be at least 100,000 years old. This is far older than the current known oldest species, a Tasmanian plant that is believed to be 43,000 years old.

Breakthroughs In Invisibility Cloak Technology
Scientists Make 'Invisibility Cloak' Breakthrough -- The Telegraph
Scientists in the United States have made a further step towards creating an "invisibility cloak" by masking a large, free-standing object in three dimensions.
The lab work is the latest advance in a scientific frontier that uses novel materials to manipulate light, a trick that is of huge interest to the military in particular.
Reporting in the New Journal of Physics, researchers at the University of Texas in Austin cloaked a 7.2-inch cylindrical tube from light in the microwave part of the energy spectrum.
Those hoping for a Harry Potter-style touch of wizardry will be disappointed however. To the human eye, which can only perceive light in higher frequencies, there would have been no invisibility.

A quick test that tells if your loved one is at risk of Alzheimer’s disease has been devised by doctors.
The 21-question test distinguishes between normal absent-mindedness and the more sinister memory lapses that may signal the early stages of dementia.
The questions are designed to be answered by a spouse or close friend.
The Alzheimer’s Questionnaire, which is almost 90 per cent accurate, measures mild cognitive impairment – the slight memory lapses that can be a precursor of the disease.

More Internet Censorship On The Way
Posts on Google's Blogger service will now be taken down if they violate local laws - so in repressive regimes, governments may be able to use local speech laws to block controversial posts
Google Joins Twitter In Censorship Storm: Site May Now Block Blog Posts In Line With Requests From Oppressive Regimes -- Daily Mail
* Blog posts will be blocked at national government request
* Campaigners fear 'the end of the global internet community'
* But Google claims move will allow MORE free speech
Google's informal motto is 'don't be evil', but a huge change to its Blogger service could see the search giant help oppressive governments stamp out voices of protest.
Bloggers who have relied on the popular service to organise dissent as seen during the Arab Spring could find their posts being blocked by Google itself.
The company will now block posts or blogs from being seen in a country if they their local laws, handing a victory to regimes that crack down on free speech to keep a lid on dissent.

What Happens When Our Brain Ages
Study Links 24% of Intelligence Changes Over a Person's Life to Genetic Factors.
Nearly a quarter of the changes often seen in a person's intelligence level over the course of a lifetime may be due to genes, a proportion never before estimated, new research shows.
The study suggests that genes may partly explain why some people's brains age better than others, even though environmental factors likely play a greater role over a lifetime.
Understanding the factors behind healthy mental aging has become an increasingly vital one for societies with large elderly populations. However, it isn't an easy task.

All Time Coldest U.S. Record Nearly Broken
Bitter Cold Records Broken In Alaska – All Time Coldest Record Nearly Broken, But Murphy’s Law Intervenes -- WUWT
Jim River, AK closed in on the all time record coldest temperature of -80°F set in 1971, which is not only the Alaska all-time record, but the record for the entire United States. Unfortunately, it seems the battery died in the weather station just at the critical moment.
While the continental USA has a mild winter and has set a number of high temperature records in the last week and pundits ponder whether they will be blaming the dreaded “global warming” for those temperatures, Alaska and Canada have been suffering through some of the coldest temperatures on record during the last week.

Flights rerouted due to solar storm; radiation rated strongest since 2003
A wave of charged particles from an intense solar storm is raising alerts about airline flights and satellite operations — and raising the prospect of stunning auroral displays.
The storm began when a powerful solar flare erupted on the sun Monday, blasting a stream of charged particles toward our planet. This electromagnetic burst — called a coronal mass ejection, or CME — started hitting Earth somewhere around 10 a.m. ET Tuesday, according to the National Oceanic and Atmospheric Administration's Space Weather Prediction Center.

Fears Of Bioterrorism Halts Research On Mutant Bird Flu
Bioterror Fears Halt Research On Mutant Bird Flu -- BBC
Scientists who created a more deadly strain of bird flu have temporarily stopped their research amid fears it could be used by bioterrorists.
In a letter published in Science and Nature, the teams call for an "international forum" to debate the risks and value of the studies.
US authorities last month asked the authors of the research to redact key details in forthcoming publications.
A government advisory panel suggested the data could be used by terrorists.
Biosecurity experts fear a mutant form of the virus could spark a pandemic deadlier than the 1918-19 Spanish flu outbreak that killed up to 40 million people.

The Hunt for Exomoons Is Heating Up
An artist's impression of a hypothetical exomoon in orbit around a planet in another planetary system. Dan Durda
Forget Exoplanets: The Hunt for Exomoons Is Heating Up
The universe seems almost infinitely reductive: our galaxy rotates around a central hub, planets orbit their planet stars, moons orbit their parent planets, and the odd moonlet may even orbit a moon.
Almost from the moment astronomers began finding planets around distant stars, they thus began talking about the moons that might orbit those alien worlds. It wasn't that they had any hope of discovering something as tiny as a moon: the smallest things they could find at the time were giant planets like Jupiter. But if a Jupiter happened to orbit in its star's Goldilocks Zone, where temperatures were relatively balmy, and if that Jupiter happened to have a moon about the size of Earth — not impossible, surely — then that hypothetical moon might have a chance of harboring life. That's a lot of ifs, which made talk of so-called exomoons seem like more of a marketing gimmick designed to gin up public interest in exoplanet science than a serious area of research.

US Army Unveils 1.8 Gigapixel Camera Helicopter Drone -- BBC
New helicopter-style drones with 1.8 gigapixel colour cameras are being developed by the US Army.
The army said the technology promised "an unprecedented capability to track and monitor activity on the ground".
A statement added that three of the sensor-equipped drones were due to go into service in Afghanistan in either May or June.
Boeing built the first drones, but other firms can bid to manufacture others.
"These aircraft will deploy for up to one full year as a way to harness lessons learned and funnel them into a program of record," said Lieutenant Colonel Matthew Munster, product manager at the US Army's Unmanned Aerial System Modernization unit.

Massive Solar Storm Heading Our Way
It's coming this way: The CME, seen by Nasa's STEREO-B spacecraft, can be seen blasting out from the Sun on the right-hand side (circled)
Massive Solar Storm 'Could Knock Out Radio Signals' Over Next Three Days, Warn Scientists -- Daily Mail
Skywatchers will be hoping for clear skies from today because particles from a recent solar storm will slam into Earth and produce amazing Northern Lights, or auroras.
On the downside, experts expect radio blackouts for a few days, caused by the radiation from the flare – or coronal mass ejection (CME) – causing magnetic storms.
The flare is part of a larger increase in activity in the Sun, which runs in 11-year cycles. It is expected to peak around 2013.

Where Science And The Search For Understanding Can Produce Mankind's Worst Nightmare
This transmission electron micrograph taken at a magnification of 150,000x, reveals the ultrastructural details of an avian influenza A (H5N1) virion, pictured by the United States government's Centre for Disease Control.
Studies Of Deadly H5N1 Bird Flu Mutations Test Scientific Ethics -- L.A. Times
Dutch scientists have created a version of the deadly H5N1 bird flu that's easily transmitted. In an unprecedented move, a U.S. board asks that some details of the research not be published.
In a top-security lab in the Netherlands, scientists guard specimens of a super-killer influenza that slays half of those it infects and spreads easily from victim to victim.
It is a beast long feared by influenza experts, but it didn't come from nature. The scientists made it themselves.
Their noxious creation could help prevent catastrophe in the battle against the deadly H5N1 bird flu that has ravaged duck and chicken flocks across Asia and elsewhere since the mid-1990s but has mostly left our species alone — for one crucial reason. Though H5N1 kills with brutality when it takes hold in a human, it infects extremely rarely and doesn't go on to easily spread between people.
Public health officials have long fretted that the virus may one day find a way to do so.

Previous Post: A Bioterror Weapon That Can Easily Kill Billions
My Comment: From what I have been reading, this genetically engineered virus is incredibly lethal (60%). And while the desire is to now limit it`s findings, the sad fact is that we are now faced with a situation in which "Pandora`s Box" has been opened, and there are now too many people who are aware of its findings.

We Should Scour The Moon For Ancient Traces Of Aliens, Say Scientists -- The Guardian
Online volunteers could be set task of spotting alien technology, evidence of mining and rubbish heaps in moon images.
Hundreds of thousands of pictures of the moon will be examined for telltale signs that aliens once visited our cosmic neighbourhood if plans put forward by scientists go ahead.
Passing extraterrestrials might have left messages, scientific instruments, heaps of rubbish or evidence of mining on the dusty lunar surface that could be spotted by human telescopes and orbiting spacecraft.

Armageddon Super Virus Recipe: Keep Secret Or Publish? -- Sydney Morning Herald
To publish or not to publish?
That is the question gripping scientists after virologists said they had developed a bird flu virus - with a 60 per cent human mortality rate - that could spread as easily as the common cold.
Some fear the virus, if it fell into the wrong hands, could be modified by bioterrorists into a weapon that kills billions of people.

Oldest Evidence Of Violence Between Humans Unearthed In China
Ancient Skull Found In China May Be Oldest Evidence Of Violence Between Humans -- The Telegraph
An ancient skull discovered in China may be the oldest evidence of violence between humans, according to researchers.
A fracture on the right temple of the skull is likely to have been caused by a blow to the side of the head some 150,000 to 200,000 years ago.
“There are older cases of bumps and bruises and cases of trauma,” said Erik Trinkaus from Washington University in St Louis, US, to the BBC.”
But this is the first one I am aware of where the most likely interpretation is getting whooped by someone else – to put it bluntly.”
The skull was unearthed in a cave near Maba in 1958 but its significance only came to light recently.

A new survey on health care is revealing that you may not be getting what you pay for if you check into a U.S. hospital.
The U.S. healthcare system is more effective at delivering high costs than quality care than other developed nations, according to the study, conducted by the Organization for Economic Cooperation and Development, or OECD.
It found first-rate treatment for cancer but insufficient primary care for other ailments.

The Construction of NASA's Next Mars Rover
This artist's concept depicts the rover Curiosity, of NASA's Mars Science Laboratory mission, as it uses its Chemistry and Camera (ChemCam) instrument to investigate the composition of a rock surface. ChemCam fires laser pulses at a target and views the resulting spark with a telescope and spectrometers to identify chemical elements. The laser is actually in an invisible infrared wavelength, but is shown here as visible red light for purposes of illustration. Source: NASA/JPL-Caltech
Inside Look: The Construction of NASA's Next Mars Rover -- FOX News
In May 2011, SPACE.com reporter Mike Wall visited NASA's Jet Propulsion Laboratory in Pasadena, Calif., as scientists and engineers were wrapping up work on Curiosity, NASA's next Mars rover. This is his account.
It could be a scene from a James Bond film — a glimpse into the archvillain's lair.
Anonymous white-clad workers, their faces obscured by surgical masks, cross a cavernous, high-ceilinged room. They pause to adjust or inspect large pieces of mysterious equipment, some of which is spangled with bright gold foil. It's obvious that they're building something complicated and important.

Power Source Unveiled For Cyborg Search-And-Rescue Insects
Image: The research team proposed putting two spiral energy harvesters on either side of a beetle's thorax.
Efforts to create an army of cyborg insects are being pursued by a team of US-based engineers.
The group is investigating ways to harvest energy from the creatures to power sensors and other equipment fastened to their bodies.
The team has created an energy scavenging device that is attached close to the insects' wings.
It suggested the creatures might one day be used to aid search-and-rescue operations and surveillance.
The University of Michigan team of engineers published their study in the Journal of Micromechanics and Microengineering.

Emails Question The Impact Of Climate Change
Uh Oh, Global Warming Loons: Here Comes Climategate II! -- The Telegraph
Breaking news: two years after the Climategate, a further batch of emails has been leaked onto the internet by a person – or persons – unknown. And as before, they show the "scientists" at the heart of the Man-Made Global Warming industry in a most unflattering light. Michael Mann, Phil Jones, Ben Santer, Tom Wigley, Kevin Trenberth, Keith Briffa – all your favourite Climategate characters are here, once again caught red-handed in a series of emails exaggerating the extent of Anthropogenic Global Warming, while privately admitting to one another that the evidence is nowhere near as a strong as they'd like it to be.
