Google Threatening To Leave China Over Hacking & Email Leak

Posted by: Audiegrl

Google Inc. will stop censoring its search results in China and may pull out of the country after discovering that computers hackers had tricked human rights activists into opening their e-mail accounts to outsiders.

The change-of-heart announced Tuesday heralds a major shift for Google, which has repeatedly said it will obey Chinese laws that require some politically and socially sensitive issues to be blocked from search results that are available in other countries

Google disclosed in a blog post that it had detected a “highly sophisticated and targeted attack on our corporate infrastructure originating from China.” Further investigation revealed that “a primary goal of the attackers was accessing the Gmail accounts of Chinese human rights activists,” Google said in the post written by Chief Legal Officer David Drummond.

Google did not specifically accuse the Chinese government. But the company added that it is “no longer willing to continue censoring our results” on its Chinese search engine, as the government requires. Google says the decision could force it to shut down its Chinese site and its offices in the country.

44-D’s Impact Diaries: How Will You Answer Dr. King’s Question?

Posted by: Audiegrl



The Corporation for National and Community Service shares a wonderful story of how Miami residents are coming together to green and beautify their community to honor the life and legacy of Dr. Martin Luther King, Jr. The Miami project is just one example of how people are coming together to serve their communities as part of January 18th’s MLK Day of Service. To find service projects in your community, visit serve.gov/MLKDay.

How will you answer Dr. King’s question?

On January, 18, 2010, people of all ages and backgrounds will come together to improve lives, bridge social barriers, and to move our nation closer to the “Beloved Community” that Dr. King envisioned. Dr. Martin Luther King devoted his life’s work to causes of equality and social justice. He taught that through nonviolence and service to one another, problems such as hunger and homelessness, prejudice and discrimination can be overcome. Dr. King’s teachings can continue to guide us in addressing our nation’s most pressing needs—poverty, economic insecurity, job loss and education.

Please volunteer with Americans across the nation on the 2010 King Day of Service and make a real in difference in your community. Fueled by President Obama’s call to service, the 2009 Martin Luther King, Jr. Day of Service experienced a historic level of participation, as Americans across the country honored Dr. King by serving their communities on the January 19 King Holiday. In total, more than 13,000 projects took place — the largest ever in the 14 years since Congress encouraged Americans to observe the King Holiday as a national day of service and charged the Corporation for National and Community Service with leading this national effort.

Thousands volunteered to prepare care packages for troops stationed in Iraq during Serve DC's Operation Gratitude project for the 2009 Martin Luther King, Jr. Day of Service in Washington, DC.

A Streamlined FAFSA by Dr. Jill Biden

posted by: Audiegrl

Secretary of Education Arne Duncan, Dr. Jill Biden, Senator Jack Reed join students and guidance counselors from Banneker Senior High School to discuss the FAFSA, January 5, 2010.

Dr. Jill Biden~~I know first-hand as a parent and as a former high school and current college instructor just how challenging and overwhelming all of the financial aid forms and paperwork can be – and it was great to see how the current forms have fewer questions, easier navigation and are more user-friendly. I spoke with students at the computer lab who expressed relief to be working on the more user-friendly FAFSA.

President Obama has challenged the nation to have the highest percentage of college graduates by 2020, and simplifying the FAFSA form is a huge step toward removing barriers to financial aid and access to higher education for all.

President Obama: Three New Initiatives to Help Community Health Centers

Posted by Audiegrl

President Barack Obama shakes hands with Health and Human Services Secretary Kathleen Sebelius after signing a memorandum expanding government funded health clinics across the country, Dec. 9, 2009

President Barack Obama shakes hands with Health and Human Services Secretary Kathleen Sebelius after signing a memorandum expanding government funded health clinics across the country

White House.gov—Two causes all Americans can get behind are initiatives to improve our health care system and create jobs in a struggling economy. In an effort to accomplish both at once, today President Obama announced that $600 million in stimulus money will go towards improving community health centers across the country:

Starting today, we’re making $88 million in funding available for centers to adopt new health information technology systems to manage their administrative and financial matters and transfer old paper files to electronic medical records. These investments won’t just increase efficiency and lower costs, they’ll improve the quality of care as well –- preventing countless medical errors, and allowing providers to spend less time with paperwork and more time with patients.

That’s the purpose of the final initiative I’m announcing today as well -– a demonstration project to evaluate the benefits of the “medical home” model of care that many of our health centers aspire to. The idea here is very simple: that in order for care to be effective, it needs to be coordinated. It’s a model where the center that serves as your medical home might help you keep track of your prescriptions, or get the referrals you need, or work with you to develop a plan of care that ensures your providers are working together to keep you healthy.

So taken together, these three initiatives –- funding for construction, technology, and a medical home demonstration –- they won’t just save money over the long term and create more jobs, they’re also going to give more people the peace of mind of knowing that health care will be there for them and their families when they need it.

And ultimately, that’s what health insurance reform is really about. That’s what the members of Congress here today will be voting on in the coming weeks.

Now, let me just end by saying a little bit about this broader effort. I know it’s been a long road. I know it’s been a tough fight. But I also know the reason we’ve taken up this cause is the very same reason why so many members from both parties are here today –- because no matter what our politics are, we know that when it comes to health care, the people we serve deserve better.

President Obama announces that the Recovery Act will provide new funding for Community Health Centers to finance new construction, modernize information technology, and build a “medical home” model. December 9, 2009

US Envoy Jon Huntsman Criticizes Coverage of Obama China Visit

Posted by Audiegrl

AP/Christopher Bodeen—Washington’s ambassador to Beijing hit out Friday at negative U.S. media coverage of President Barack Obama’s visit to China, saying it failed to take into account important progress on many issues.

Although producing no breakthroughs on key issues, Obama’s first state visit to the Asian giant that ended Wednesday was heralded by both sides as a success.

The trip was the top news story in China, drawing strong interest from the Chinese public who, surveys suggest, are largely positive in their view of the American president.

However, much of the U.S. media coverage was strongly negative, accusing Obama of failing to gain concessions on key issues such as Iran’s nuclear program and climate change, as well as being weak on human rights.

Ambassador Jon Huntsman said the reports missed the fact that the visit had yielded important progress on cooperation in areas such as clean energy, military-to-military exchanges and stopping the spread of nuclear weapons.

I attended all those meetings that President Obama had with Hu Jintao and Wen Jiabao,” Huntsman said, referring to the Chinese president and premier.

I’ve got to say some of the reporting I saw afterward was off the mark. I saw sweeping comments about things that apparently weren’t talked about, when they were discussed in great detail in the meetings,” he said.

Huntsman made the comments during a question-and-answer session with Chinese and American students attending an international relations program at elite Peking University.

He said criticism about limited Chinese exposure for Obama’s remarks at a town hall-style meeting with students in Shanghai failed to consider the ubiquity of the Internet and blogging in China, where 350 million people use the Web.

Go check some time and see how messages bounce around from Web site to Web site and blogger to blogger for a very long period of time and you’ll get a sense of what the communication revolution is all about,” Huntsman said.

44-D’s True Crime: Discovery Channel’s Jack the Ripper in America

TrueCrime-490X136

Reviewed by Audiegrl

The greatest serial killer in history has never been named. But what if we are looking in the wrong place?


In 1888, a deranged killer stalked his prey on the streets of east London at night. After 121 years since the murder and mutilation of at least five prostitutes, the case remains unsolved and the true identity of Jack the Ripper has never been known. The world’s greatest criminal investigators have focused on searching for answers in London. However, in the 1890s a series of horrific murders took place across the United States in New York, San Francisco, Galveston and Atlanta, that mirrored the attacks in attacks in the UK. In this one hour special, Discovery Channel’s viewers will witness the new evidence, science and analytical techniques being used to reveal the true identity of Jack the Ripper.

NYPD Cold Case Detective Ed Norris

The Discovery Channel’s documentary, Jack the Ripper in America focuses on Detective Ed Norris, former head of the NYPD Cold Case Unit, who investigates and uncovers new evidence not seen since the time of the murders. In trying to solve the 118 year old murder of New York prostitute Carrie Brown, he begins to note the similarities between her murder and the famous Whitechapel murders in London. Brown’s murderer had a three-stage MO (strangled, penetrating wound, pulled apart) Because of the unusual and gruesome nature of the crime, the press of the day, immediately began asking the question, “Is Jack the Ripper in New York“. Norris sees the same unusual ‘signature‘ in both the London and New York killers. They both kill prostitutes by strangling, cutting the throat, and eviscerating the body. For Norris this indicates that he might be looking at the same killer.

Carrie Brown aka Old Shakespeare

Carrie Brown aka Old Shakespeare

The key in all cold cases is finding the clues missed by the original investigators. Although, Brown was murdered on April 23, 1891, Norris decides to let a new set of eyes look at the evidence. Enter Dr. Jonathan Hayes, the Manhattan Senior Medical Examiner. Dr. Hayes combs through the autopsy report of Carry Brown. He reaches some interesting conclusions, including a special marking on the body, which I won’t reveal here, you’ll have to watch the show. On August 7th, 1891, another unidentified prostitute is murdered with the same MO as Brown, and pulled from the East river. Visiting the New York Municipal Archives, Norris finds that the old newspapers of that time, reveal another shocking detail. The killer actually wrote to the NYPD, before the murder of Carry Brown. His letter is recreated below:

Capt. Ryan,

You think that “Jack the Ripper” is in England, but he is not, I am right here and I expect to kill somebody by Thursday next, and so get ready for me with your pistols, but I have a knife that has done more than your pistols. Next thing you will hear of some woman dead.

Yours truly,

Jack the Ripper

Richard Jones

Detective Norris wants to get into Jack’s head, and walk in his foot steps. He feels that he was an organized killer that took advantage of the conditions of the time: no ambient street lighting, a black curtain of smoke over the city caused by burning low quality coal, and counting on his victims to naturally take him to the dark, secluded places used in the prostitution trade. Norris takes viewers through a summary of the Ripper murders by using re-enactments and walking through the crime scenes. Next, Norris consults London historian Richard Jones, owner of Ripper Walking Tours and author of Uncovering Jack the Ripper’s London. Jones has spent more than two decades investigating the Whitechapel murders. He asks Jones if any of the serious Ripper suspects had ever traveled to the United States after the death of Mary Kelly. Jones provided him with three names: Severin Klosowski, Francis Tumblety, and James Kelly.

Known as the From Hell or Lusk Letter

Norris then consults with Sheila Kurtz, a Forensic Hand Writing Analyst, Master Graphologist and President of Graphology Consulting Group. Kurtz had successfully worked on the Son of Sam case among many others. After reviewing samples of the Ripper’s hand writing, Kurtz identified the writer as a very disturbed individual, who she said, “I wouldn’t want to be in his company“. For additional details on her analysis please visit her blog. The graphic to the left shows the letter was purportedly written in 1888 by Jack the Ripper.

Dr Thomas Bond

Dr. Thomas Bond

Norris then paid a visit to Britain’s National Archives. The archives hold thousands of original documents in the Ripper case. There, Norris discovers a document not previously used in the investigation. A profile of the killer. Sir Robert Anderson, the head of the police Criminal Investigation Departments, asked Dr Thomas Bond, Britain’s top police surgeon in 1888 to examine material connected with the Whitechapel murder investigation. Bond wrote a 19th-century version of a modern day unsub profile, based on personally examining the body of Mary Kelly and reading the autopsy reports on the first four victims. In the report, he describes in detail the type of person they should be investigating. Dr. Bond was sure that all five women had been killed by the same hand, because the throats of all victims had been cut in a similar way and the victims were presumably lying down when murdered. (for additional details on Dr. Bond’s profile, click here to read the report) Norris ultimately uses this 121 year old profile to narrow the three suspects down to one name. James Kelly. In the world of police parlance, Norris says that “Kelly looks good“.

Jack the Ripper victims: Polly Nichols, Annie Chapman, Elizabeth Stride, Catharine Eddowes, Mary Kelly

In 1883, James Kelly only one month married, argues with his wife and accuses her of being unfaithful. In a psychotic rage, he uses the methods of strangulation and throat slashing to kill her. Kelly is caught, convicted and sentenced to die by hanging. Then his employer comes forward and explains that he believes Kelly is mentally disturbed. Kelly was then examined by a alienist and committed to the Broadmoor Criminal Lunatic Asylum. Kelly’s psychiatric report has been sealed for over 125 years, until Norris examines it.

Broadmoor Old Gate

Broadmoor Criminal Lunatic Asylum

In 1863, Broadmoor was the first custom-built asylum to house criminal lunatics. In Broadmoor, Kelly is a outwardly a model prisoner, but at the same time he is secretly planning his escape. Working in the asylum’s carpentry shop, he cunningly uses a piece of medal he carved into a key to aid his escape. In January of 1888, Kelly escaped and just disappeared. At that time a series of stabbings and slashing attacks of women start in London. Three victims: Annie Millwood, (February 25, 1888, stabbed repeatedly, but survived), Ada Wilson, (March 28, 1888, slashed in the throat, but survived), and Martha Tabram, (August 7, 1888, stabbed 23 times, did not survive). Norris feels these are the early attempts of Jack the Ripper, who like many serial killers, escalates and only gets more brutal over time. After these three attacks, the first London Ripper murder occurs. Surprisingly, Kelly was once considered a suspect by London police, but after only minimal checking at his old residence, they simply gave up, and were never able to find him. With the huge amount of pressure they were under, the case against Kelly went cold…

blank
Astonishingly, in 1927…forty years later, a much older Kelly voluntarily returns to the insane asylum and began to chronicle his travels. A typed copy of Kelly’s confession letter survives in the National Archives, and Norris is the first detective to read it. In the letter, Kelly describes having “problems dealing with society“, and being “overtaken with feelings of envy, jealousy, and malice“. Kelly states, “the thing has been hard because of all kinds of ‘skank’” (a term he uses to refers to women of low moral character) and “I’ve been on the warpath since I left Broadmoor Asylum.” Also in his letter, he admits to traveling to London after his escape, and more interestingly he tells of traveling to the United States and arriving in New York conveniently before the Carrie Brown murder. He was by profession, a trained upholsterer, and would have known quiet a bit about knives and how to use them effectively for the purpose of murder. Kelly also mentioned traveling to many cities in the US before returning to England and admitted that he came to the US many times over a period of 40 years.

USS Zaandam

First Norris wanted to check to make sure that Kelly’s confession matched up with actual travel records of the day. In Britain’s National Maritime Museum, they kept track of every ship that came to the United States. Kelly said he traveled to America aboard an Anglo-German steamer named the Zaandam that sailed from Rotterdam to New York. At the museum, Norris not only confirmed the ship existed, but that it sailed from Rotterdam to New York on October 7, 1890—two years after the last Ripper murder in London (11/88) and months before the April 23, 1891 murder of Carrie Brown in New York. You might be thinking, “How does a ‘wanted man’ get into the United States without detection?” Professor Dan Citrum is an expert in 19th-century immigration and explains how easily it could have been done. Remember this was before Ellis Island was established, so getting in and out of the country was very easy. No drivers licenses, no passports, and no photo id whatsoever. Many people back then, came to this country to start over, and remake themselves and get lost in the huge crowds of New York city. In his confession, Kelly admits to changing his name once his ship arrives to ‘John Miller‘, one of the most common names both then and now. Kelly used his new name like a disguise to blend in and escape police scrutiny.

Knowing from experience that many serial killers travel extensively, to avoid detection, Detective Norris plots the cities Kelly claims to have visited against the murders written about in the newspapers. He begins to see similarities in Ripper-like murders committed in other cities: New York NY, Trenton, NJ, Galveston, TX, New Orleans, LA, Philadelphia, PA, Baltimore, MD, Jackson, CA, San Francisco, CA, Denver, CO. Each of these murders occurred during the time that Kelly, thorough his confession letter, said he was in that city. Even the city newspapers asked the same question “Is this the work of Jack the Ripper” and “Is this the fiend of Whitechapel?” and “Has Jack the Ripper Invaded Texas at Last“. Detective Norris identified twelve murders across five states in just four years…and remember, Kelly was gone for forty years…you can do the math. To read an amazing collection of news reports, please visit Casebook: Jack the Ripper.

Using a asylum photo of Kelly provided by the National Archives, he was able to see what Kelly looked like at age 67. Norris then contacted Steve Mancusi, a NYPD senior forensic artist who has helped solve the most difficult cases for the last 30 years. He wanted Mancusi to use forensic imaging technology normally used for age-progression in missing child cases, but with this case, he wanted him to reverse the effects of aging, to show what Kelly would have looked like in his 30’s. The striking illustration below on the right is based on their findings.

Both illustrations of Jack the Ripper

The left composite, was drawn based on 118 year old eye-witness accounts of Jack the Ripper in London. They examined different witness statements and used modern day forensics to come up with a portrait of the killer, even indicating what type of hat he wore.

The drawing on the right, is the result of Mancusi shaving 40 years off of James Kelly’s photo at age 67. As you can see, once they added the type of hat mentioned by eye witnesses, the drawings are a very close match.

In the end, there is no doubt in Norris’ mind that he has found Jack the Ripper. We may never know. John Kelly died of natural causes in 1929 inside Broadmoor Asylum and took his secrets to his grave. In my opinion, Jack the Ripper in America was very well done and is a must-see for all forensic buffs and amateur Ripperologists. I’m interested in seeing further research, analysis and discussion of Norris’ theory. Regarding any factual errors in this post, I apologize in advance, and encourage everyone to let me know what needs to be corrected.

Time After Time

On a lighter note, anybody remember the movie “Time After Time” starring Malcolm McDowell, John Warner and Mary Steenburgen? McDowell played H.G. Wells, who uses his time machine to chase his friend, Warner (aka Jack the Ripper) through the streets of modern day (1979) San Francisco. After watching Norris’ documentary, maybe Hollywood’s silly (but entertaining) version of the Ripper story had a sliver of truth to it after all. 😉

The Secret of Prisoner 1167: Was This Man Jack the Ripper? by James Tully


Hat tip and special thanks to Roy Corduroy for his suggestion to add this book to this post. Casebook: Jack the Ripper gives this book a three-starred review:

A triumphant achievement on the part of Jim Tully, well-researched and written. James Kelly is his suspect, a lunatic upholsterer and wife-murderer who is actually in the Guinness book of world records for his escape from Broadmoor asylum. Tully weaves a fascinating story, regardless of your feelings on Kelly as a suspect. Recommended.

The Care They Were Promised and the Benefits That They Have Earned

President Barack Obama

President Barack Obama presents new proposals to care for veterans to an audience of Wounded Warriors in the Eisenhower Executive Office Building on 4/9/09.

President Barack Obama presents new proposals to care for veterans to an audience of Wounded Warriors in the Eisenhower Executive Office Building on 4/9/09.

It’s time to give our veterans a 21st-century VA. Over the past few months we’ve made much progress towards that end, and today I’m pleased to announce some new progress.
Under the leadership of Secretary Gates and Secretary Shinseki, the Department of Defense and the Department of Veterans Affairs have taken a first step towards creating one unified lifetime electronic health record for members of our armed services that will contain their administrative and medical information — from the day they first enlist to the day that they are laid to rest.

Currently, there is no comprehensive system in place that allows for a streamlined transition of health records between DOD and the VA. And that results in extraordinary hardship for a awful lot of veterans, who end up finding their records lost, unable to get their benefits processed in a timely fashion. I can’t tell you how many stories that I heard during the course of the last several years, first as a United States senator and then as a candidate, about veterans who were finding it almost impossible to get the benefits that they had earned despite the fact that their disabilities or their needs were evident for all to see.

And that’s why I’m asking both departments to work together to define and build a seamless system of integration with a simple goal: When a member of the Armed Forces separates from the military, he or she will no longer have to walk paperwork from a DOD duty station to a local VA health center; their electronic records will transition along with them and remain with them forever.~~President Barack Obama

If we only have $10 to spend in the entire federal government, then we are convinced that we have to spend six of it caring for those who come home in need. We will spend all six before we spend it on anything else — on the elderly, on children, on the poor, on our roads, on our security — because this is the only genuinely sacred obligation this nation has. The service that you and thousands and thousands of others who went before you in Iraq over the last six years — the services you’ve performed have come at great cost for some. Some of our warriors and their families have paid a much steeper price than others. Some had given their lives, the ultimate sacrifice, and we honor their memory.

But the best way to honor their memory, of those thousands — over 14,000 seriously injured coming home from the wars which we are engaged in and have been engaged in — we owe them the obligation to — we know we can never fully repay it, but we know we owe them the obligation to provide them the absolute best medical care and service they need. Some will need that for the rest of their lives. Their life expectancies will be 35 to 40 years, and some will need care for the entirety of those lives.~~Vice President Joe Biden

Science Faction: Shrimp’s eye points way to better DVDs

posted by GeoT
Shrimp use remarkable light-sensitive cells that rotate the plane of polarization in light as it travels through the eye.

LONDON (Reuters) – The amazing eyes of a giant shrimp living on Australia’s Great Barrier Reef could hold the key to developing a new type of super high-quality DVD player, British scientists said on Sunday.

Mantis Shrimp

Mantis Shrimp


Mantis shrimps, dubbed “thumb splitters” by divers because of their vicious claws, have the most complex eyes in the animal kingdom.
They can see in 12 primary colors, four times as many as humans, and can also detect different kinds of light polarization — the direction of oscillation in light waves.
Now a team at the University of Bristol have shown how the shrimps do it, using remarkable light-sensitive cells that rotate the plane of polarization in light as it travels through the eye.
Manmade devices do a similar thing in DVD and CD players but they only work well for one color, while the shrimp’s eye operates almost perfectly across the whole visible spectrum from near ultra-violet to infra-red.
Transferring the same multi-color ability into a DVD player would result in a machine capable of handling far more information than a conventional one.
“The mechanism we have found in this eye is unknown to human synthetic devices. It works much, much better than any attempts that we’ve made to construct a device,” researcher Nicholas Roberts told Reuters.
He believes the “beautifully simple” eye system, comprising cell membranes rolled into tubes, could be mimicked in the lab using liquid crystals.
Details of the mantis shrimp research were published in the journal Nature Photonics.
Just why the mantis shrimp needs such a rarefied level of vision is unclear, although researchers suspect it is to do with food and sex.

Web Surf to Save Your Aging Brain

Posted by Audiegrl

Seniors_computersHealthDay/Amanda Gardner—Surfing the Internet just might be a way to preserve your mental skills as you age.

Researchers found that older adults who started browsing the Web experienced improved brain function after only a few days.

You can teach an old brain new technology tricks,” said Dr. Gary Small, a psychiatry professor at the Semel Institute for Neuroscience and Human Behavior at the University of California, Los Angeles, and the author of iBrain. With people who had little Internet experience, “we found that after just a week of practice, there was a much greater extent of activity particularly in the areas of the brain that make decisions, the thinking brain — which makes sense because, when you’re searching online, you’re making a lot of decisions,” he said. “It’s interactive.”

Seniors_computersbSmall is co-author of the research, which was scheduled to be presented Monday in Chicago at the Society for Neuroscience annual meeting.

This makes intuitive sense, that getting on the Internet and exploring and getting new information and learning would help,” said Paul Sanberg, director of the University of South Florida Center of Excellence for Aging and Brain Repair in Tampa. “It supports the value of exploring the Internet for the elderly.”

Most experts now advocate a “use-it-or-lose-it” approach to mental functioning.
