Chinese Researchers Have Revealed A 'Ghost Cape'

The prototype 'ghost cloak' created by the team. It can distort light and make a ghost device, in the upper picture, appear as something else 

The 'Ghost Cape' That Could Make Fighter Jets Look Like Passenger Planes -- Daily Mail 

* Groundbreaking technology can make an object appear to be something else
* Technology could be used to make a jet fighter appear to be a passenger plane, or a soldier appear to be a tree
* Researchers say the technique is far simpler than current 'cloaking' devices

Chinese researchers have revealed a 'ghost cape' that can make one object appear to look like another.

The team from Southeast University in Nanjing, China say their technique is far simpler that other invisibility devices, because instead of making an object disappear entirely, it makes it look like something else.

The technique scatters incoming light to create two 'ghost' images either side of the cloaked object.

My Comment: Until I see Chinese fighter jets looking like passenger jets .... I am deeply skeptical of this report.

No One Will Do Your Laundry In Space

 In Space, No One Will Do Your Laundry -- Popular Mechanics 

University of Rhode Island design professor Karl Aspelund wants you to think about astronaut socks. In fact, he hopes his work with the 100 Year Starship Project—figuring out what kind of clothes space travelers will need for a long-duration mission—will change the way you dress, too.

How did you get interested in what clothes astronauts could use on a 100-year-long trip into space?

I had an NPR driveway moment when I heard Dr. Mae Jemison talking about the 100 Year Starship; I had to sit and listen to the whole thing. I immediately got this idea, and ran inside to email her saying, "Okay, you’re planning this long trip, but have you thought about what you’ll wear?" She hadn’t. Textiles and clothing are so integral to our lives, but that gets taken for granted.

My Comment: It must smell pretty bad up there .... but if you are living in it all the time, who will notice.

A Relative from the Tianyuan Cave: Humans Living 40,000 Years Ago Likely Related to Many Present-Day Asians and Native Americans -- Daily Science 

Jan. 21, 2013 — Ancient DNA has revealed that humans living some 40,000 years ago in the area near Beijing were likely related to many present-day Asians and Native Americans.

An international team of researchers including Svante Pääbo and Qiaomei Fu of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, sequenced nuclear and mitochondrial DNA that had been extracted from the leg of an early modern human from Tianyuan Cave near Beijing, China.

Scheme To Clone Neanderthal Baby Disowned By Harvard Geneticist Who "Promoted" It


Lost In Translation: Harvard Geneticist Now Disowns Scheme To Clone Neanderthal Baby -- Evolution News 

The Boston Herald assures us that the geneticist who yesterday was advocating a project to clone a Neanderthal baby in fact never called for such a thing, nor is he seeking a likely and "adventurous female human" to bear the child.

It's all "Way too outlandish, and entirely untrue." A big misunderstanding. The story today is that this all stems from a mistranslation in Der Spiegel that got hyped by Britain's Daily Mail, then went global.

I commented here yesterday on the moral stupidity of the idea.

U.S. Military Wants To Hide Drones Under The Sea -- CBS

Hollywood films often show alien ships or giant monsters rising from the ocean depths to threaten humanity's existence.

The U.S. military envisions a more realistic scenario of hiding robotic drones, sensors or decoys on the ocean floor so that they can rise to the occasion when needed.

The idea of hiding sneaky spy technologies beneath the waves comes from the U.S. Defense Advanced Research Projects Agency.

The agency described its Upward Falling Payloads program as an effort to hide underwater capsules that could be triggered remotely to activate, float to the surface and release their payloads of sensor buoys or even flying drones.

The 16 Greatest Cities In Human History -- Business Insider 

What New York City was in twentieth century, London was in the the 1900s, Constantinople was in the 600s, and so forth, back to Jericho in 7000 BC.

They were the largest cities in the world, and arguably the epicenters of human civilization. These cities led mankind to new heights of culture and commerce—though in the end each of them was surpassed and some of them destroyed.

Did An 8th Century Gamma Ray Burst Irradiate Earth? -- Science Daily 

Jan. 21, 2013 — A nearby short duration gamma-ray burst may be the cause of an intense blast of high-energy radiation that hit the Earth in the 8th century, according to new research led by astronomers Valeri Hambaryan and Ralph Neuhӓuser.

The two scientists, based at the Astrophysics Institute of the University of Jena in Germany, publish their results in the journal Monthly Notices of the Royal Astronomical Society.

Mars Scientists Find ‘Strongest Evidence Yet’ That Planet May Have Supported Life -- National Post

Scientists believe they may have found the ‘strongest evidence yet’ that Mars may have supported life, but it’s unlikely in the form most people would recognize.

New research published today in the journal Nature Geoscience suggests a team of scientists could have discovered the ingredients of life in a huge crater up to 5km below the planet’s surface.

The McLaughlin crater, which was made by a meteorite which smashed into Mars, is described as an area of interest for the team, led by London’s Natural History Museum and the University of Aberdeen in Scotland.

Deodorants: Do We Really Need Them? -- Science Daily

 Jan. 17, 2013 — New research shows that more than 75 per cent of people with a particular version of a gene don't produce under-arm odour but use deodorant anyway.

The study was based on a sample of 6,495 women who are part of the wider Children of the 90s study at the University of Bristol. The researchers found that about two per cent (117 out of 6,495) of mothers carry a rare version of a particular gene (ABCC11), which means they don't produce any under-arm odour.

The Pentagon (Wikipedia

9 Things You May Not Know About the Pentagon -- History

On January 15, 1943, work was completed on the new headquarters for the U.S. War Department (the modern-day Department of Defense) in Arlington, Virginia. The massive complex, commonly known as the Pentagon, was built to house the nearly 30,000 defense workers tasked with helping America win World War II. With more than 17 miles of corridors, it remains one of the largest office buildings in the world, and has become a symbol—for better and for worse—of military might. Eighty years after its completion, here are nine things you may not know about the Pentagon.

Where Did Europe`s Jews Come From?

Jews throw stones at the sea to symbolically cast off their sin on September 20, 2009 in Nice, France, as part of Rosh Hashanah, the Jewish New Year. Jews of European origin are a mix of ancestries, with many hailing from tribes in the Caucasus who converted to Judaism and created an empire that lasted half a millennium, according to a gene study published on Thursday. 

Gene Study Settles Debate Over Origin Of European Jews -- France24 

AFP - Jews of European origin are a mix of ancestries, with many hailing from tribes in the Caucasus who converted to Judaism and created an empire that lasted half a millennium, according to a gene study published on Thursday.

The investigation, its author says, should settle a debate that has been roiling for more than two centuries. Jews of European descent, often called Ashkenazis, account for some 90 percent of the more than 13 million Jews in the world today. According to the so-called Rhineland Hypothesis, Ashkenazis descended from Jews who progressively fled Palestine after the Moslem conquest of 638 AD.

My Comment: In short .... they came from the Middle East and the Caucasus.

Why Wolves Cannot Be Tamed

Why Dogs Can Be Tamed But Wolves Cannot -- Science 2.0 

Wolves and dogs are genetically very similar, so why did dogs become "man's best friend" while wolves remain wild? Kathryn Lord at the University of Massachusetts Amherst suggests the different behaviors are related to the animals' earliest sensory experiences and the critical period of socialization.

Not much is known about sensory development in wolf pups and assumptions are usually extrapolated from what is known for dogs - but there are significant differences in early development between wolf and dog pups, chief among them timing of the ability to walk.

My Comment: Bottom line .... wolves are tricky animals to have as a pet.

Archaeologists Believe No Spitfires Buried In Burma -- BBC 

Archaeologists hunting for World War II Spitfires in Burma believe there are no planes buried at the sites where they have been digging, the BBC understands.

The archaeologists have concluded that evidence does not support the original claim that as many as 124 Spitfires were buried at the end of the war, the BBC's Fergal Keane reports.

Wargaming.net, the firm financing the dig, has also said there are no planes. But project leader David Cundall says they are looking in the wrong place.

Iran Strengthened Cyber Capabilities After Stuxnet: U.S. General -- Reuters

(Reuters) - Iran responded to a 2010 cyber attack on its nuclear facilities by beefing up its own cyber capabilities, and will be a "force to be reckoned with" in the future, a senior U.S. Air Force official told reporters on Thursday.

General William Shelton, who heads Air Force Space Command and oversees the Air Force's cyber operations, declined to comment about Iran's ability to disrupt U.S. government computer networks, but said Tehran had clearly increased its efforts in that arena after the 2010 incident.

While no government has taken responsibility for the Stuxnet computer virus that destroyed centrifuges at Iran's Natanz uranium enrichment facility, it was widely reported to have been a U.S.-Israeli project.

The Role Of Soot In Climate Change

The burning of wood is a major source of black carbon the world over. 

Climate Change: Soot's Role Underestimated, Says Study -- BBC 

Black carbon, or soot, is making a much larger contribution to global warming than previously recognised, according to research.

Scientists say that particles from diesel engines and wood burning could be having twice as much warming effect as assessed in past estimates.

They say it ranks second only to carbon dioxide as the most important climate-warming agent. The research is in the Journal of Geophysical Research-Atmospheres.

Black carbon aerosols have been known to warm the atmosphere for many years by absorbing sunlight. They also speed the melting of ice and snow.
