NYC police: Notes to Obama, mayor had gun threats

WASHINGTON (AP) ? A suspicious letter mailed to the White House was similar to two threatening, poison-laced letters on the gun law debate sent to New York Mayor Michael Bloomberg, one of the nation's most potent gun-control advocates, officials said Thursday.

The Secret Service said the letter was addressed to President Barack Obama and was intercepted by a White House mail screening facility. Two similar letters postmarked in Louisiana and sent to Bloomberg in New York and his gun control group in Washington contained traces of the deadly poison ricin.

It wasn't immediately clear whether the letter sent to Obama contained ricin. It was turned over to the FBI's Joint Terrorism Task Force for testing and investigation.

The two Bloomberg letters, opened Friday in New York and Sunday in Washington, contained an oily pinkish-orange substance.

New York Police Department Commissioner Raymond Kelly said Thursday that all three letters apparently came from the same machine or computer and may be identical but referred specific questions to the FBI.

The body of the letter mailed to New York was addressed to "you" and referenced the gun control debate. Kelly said the unsigned letter says, in so many words: "Anyone who comes for my guns will be shot in the face." He refused to quote directly from the letter, saying he didn't want to do the author's bidding.

Bloomberg has emerged as one of the country's most important gun-control advocates, able to press his case with both his public position and his private money.

The New York letter was opened at the city's mail facility in Manhattan in a biochemical containment box, which is a part of the screening process for mayor's office mail.

"In terms of the processes and procedures that are in place now we think they worked," Kelly said. "This is sort of an effect of the post-9/11 world that we live in that these checks and facilities are in place and the system worked."

The second letter was opened Sunday by Mark Glaze, director of Mayors Against Illegal Guns, the Washington-based nonprofit Bloomberg started.

The letter Glaze opened tested positive for ricin initially. The other letter to Bloomberg at first tested negative but tested positive at a retest Wednesday.

The postal workers union, citing information it got in a Postal Service briefing, said the letters bore a Shreveport, La., postmark. Kelly would not comment on the origin of the letter.

Louisiana State Police spokeswoman Julie Lewis said state authorities have deferred to the FBI and have not opened an investigation. The Shreveport postal center handles mail from Louisiana, Texas and Arkansas, so the letter could have come from any of those states, Lewis said.

The people who initially came into contact with the letters showed no symptoms of exposure to the poison, but three officers who later examined the New York letter experienced minor symptoms that have since abated, police said. The mayor visited the mailroom on Thursday but made no public comments on the topic.

On Wednesday, he said he didn't know why they were sent.

One of the letters "obviously referred to our anti-gun efforts, but there's 12,000 people that are going to get killed this year with guns and 19,000 that are going to commit suicide with guns, and we're not going to walk away from those efforts," said Bloomberg, adding that he didn't feel threatened.

According to the federal Centers for Disease Control and Prevention, ricin is a poison found naturally in castor beans. Symptoms can include difficulty breathing, vomiting and redness on the skin depending on how the affected person comes into contact with the poison.

The letters were the latest in a string of toxin-laced missives, but authorities would not say whether the letters to Bloomberg and Obama were believed to be linked to any other recent case.

In Washington state, a 37-year-old was charged last week with threatening to kill a federal judge in a letter that contained ricin. About a month earlier, letters containing the substance were addressed to Obama, a U.S. senator and a Mississippi judge. One of the letters postmarked in Memphis, Tenn., was traced back to Tupelo, Miss., and a Mississippi man was arrested.

Bloomberg and Boston Mayor Thomas Menino founded Mayors Against Illegal Guns, which now counts more than 700 mayors nationwide as members. It lobbies federal and state lawmakers, and it aired a spate of television ads this year urging Congress to expand background checks and pass other gun-control measures after the school shooting in Newtown, Conn. The background check proposal failed in a Senate vote in April, and other measures gun-control advocates wanted ? including a ban on sales of military-style assault weapons ? have stalled.

Separately, Bloomberg also has made political donations to candidates who share his desire for tougher gun restrictions. His super PAC, Independence USA, put $2.2 million into a Democratic primary this winter for a congressional seat in Illinois, for example. Bloomberg's choice, former state lawmaker Robin Kelly, won.

Fighting ads: The top nine fighter commercials

When fighters aren't in the cage beating people up, many of them are also working as actors in commercials. In most ads, they're playing the tough role of fighters. Here are the best of the best.

9. Matt Hughes for Xyience: Matt Hughes is busy. Really, really busy. He doesn't have time to eat breakfast, so he's opting for a protein bar.

8. Fedor Emelianenko for Snickers: What's great about this ad is Fedor's bemused smile. It's the same smile that he wore during press conferences and before he walked out to win 34 times.

7. GSP for Sportscenter: In the first of his two spots in this list, the UFC welterweight champion dares ESPN anchor and University of Missouri alum Jon Anderson to walk into his cage-covered cubicle. Like all Missouri alums, Anderson is wise and decides to stay out of GSP's way.

6. Vitor Belfort for Gillette: Not only is Vitor Belfort watching you shave, his whole gym is watching you shave. And judging you.

5. Mirko Cro Cop for ... something: For some reason, Cro Cop is an executive who knocks out coffee beans. No clue what it's trying to sell, which makes it effective advertising.

4. Mark Coleman and Wanderlei Silva for Schick: Apparently, fighters make great pitchmen for razors. This is a classic from when these two men were the kings of Pride FC. Though Pride is no longer, Coleman is retired and Silva has many more fights behind him than in front of him, their ad is everlasting.

3. Clay Guida for Currie Ford: It's a shame you all don't live in Chicagoland, because you would be treated to these ads all the time. Next time I'm in a press gaggle, I will work hard to be as hilariously animated as the reporters in this ad.

2. GSP for Nexus: One of the most common criticisms of GSP is that he can be a little boring and doesn't show his personality. This commercial changes that. GSP shows off a goofy side in this ad.

1. Anderson Silva for Burger King: The pound-for-pound king is also the advertising king. He serenades a cheeseburger here, and yet is just as frightening as ever.

Five Weird Future Predictions in 'After Earth'

Humans aren't the luckiest creatures in "After Earth," a new science fiction movie that hit theaters around the United States today (May 31).

Actor?Will Smith and his son Jaden Smith star as two future humans that crash-land on Earth 1,000 years after humans abandoned the planet for greener pastures. Jaden's character Kitai is forced to fight and run his way across the now alien Earth to save the life of his injured father who remains on the ship.

"After Earth" presents an incredibly bleak future for humans as a space-traveling species. Here are five strange aspects of humanity's future on and off our home planet as presented by the minds behind "After Earth." [See Photos from "After Earth"]

Warning: Spoilers ahead.

Humans don't live on Earth anymore

In the movie, humans have deserted Earth to live on the planet Alpha Prime, a world seemingly within our galaxy but outside of the solar system.

People have created advanced, manta ray-shaped spaceships that are able to traverse interstellar distances. When Kitai and his dad Cypher crash-landed on Earth, they were heading to a different planet, far from Alpha Prime and Earth. The propulsion system used in the movie is not explained, but it's definitely far beyond anything we have at our disposal today.

We can't breathe on Earth

At a certain point in the history presented by "After Earth," humans were forced to leave the planet because it basically kicked us out. The Earth began remaking itself into a hostile place for humans to live while still leaving all other oxygen-breathing animals unscathed.

As Kitai runs to find help on the now pristine surface of Earth, he has to take doses of an inhaler that allows him to breathe the air on the forbidden planet. At one point a parasite poisons the young man, and a group of angry baboon-like mammals chase him through a jungle.

Although humans have been off Earth for 1,000 years, it still doesn't seem to like us very much.

A computer is your doctor

As Cypher sits on the ship, coaching his son through the dangers before him on Earth, he is also trying his best to heal his broken legs.

The decorated general in a United Nations space peacekeeping group performs a bypass on himself, without anesthesia, at the urging of a computer program designed to diagnose and possibly heal an injured person on a long-duration mission. Technology aside, whether any future humans will have the stomach to perform surgery on themselves is an open question. ?

Aliens exist, and they're mean

When humans got to Alpha Prime, they also make first contact with a group of aliens that already inhabit the planet. The advanced life forms were hostile and created monsters that smell human fear to seek and destroy all people on their planet.

Ursas (the monsters) are blind, but they can smell and track the pheromones the human body expels when frightened. Whether such an ability could ever be developed in real-life remains to be seen.

The spaceship that crash-landed on Earth was also carrying an Ursa along with its other human cargo. The monster miraculously survives the accident, can breathe the air on Earth and is prowling the crash site looking for human prey. Kitai needs to overcome his fear to hopefully survive and defeat the alien horror.

We wear suits that sense danger

Our clothes are much cooler in the future.

While running around Earth, Kitai's suit changes depending on his environment. When it senses that danger is approaching, his clothing turns black and armor-like. When it's cold, the suit turns blue and tan, but it doesn't seem to provide any added warmth. Still, it's a useful invention most current humans wouldn't turn down.

Clear photos in dim light: New sensor a thousand times more sensitive than current camera sensors

May 30, 2013 ? Cameras fitted with a new revolutionary sensor will soon be able to take clear and sharp photos in dim conditions, thanks to a new image sensor invented at Nanyang Technological University (NTU).

The new sensor made from graphene, is believed to be the first to be able to detect broad spectrum light, from the visible to mid-infrared, with high photoresponse or sensitivity. This means it is suitable for use in all types of cameras, including infrared cameras, traffic speed cameras, satellite imaging and more.

Not only is the graphene sensor 1,000 times more sensitive to light than current imaging sensors found in today's cameras, it also uses 10 times less energy as it operates at lower voltages. When mass produced, graphene sensors are estimated to cost at least five times cheaper.

Graphene is a million times smaller than the thickest human hair (only one-atom thick) and is made of pure carbon atoms arranged in a honeycomb structure. It is known to have a high electrical conductivity among other properties such as durability and flexibility.

The inventor of the graphene sensor, Assistant Professor Wang Qijie, from NTU's School of Electrical & Electronic Engineering, said it is believed to be the first time that a broad-spectrum, high photosensitive sensor has been developed using pure graphene.

His breakthrough, made by fabricating a graphene sheet into novel nano structures, was published this month in Nature Communications, a highly-rated research journal.

"We have shown that it is now possible to create cheap, sensitive and flexible photo sensors from graphene alone. We expect our innovation will have great impact not only on the consumer imaging industry, but also in satellite imaging and communication industries, as well as the mid-infrared applications," said Asst Prof Wang, who also holds a joint appointment in NTU's School of Physical and Mathematical Sciences.

"While designing this sensor, we have kept current manufacturing practices in mind. This means the industry can in principle continue producing camera sensors using the CMOS (complementary metal-oxide-semiconductor) process, which is the prevailing technology used by the majority of factories in the electronics industry. Therefore manufacturers can easily replace the current base material of photo sensors with our new nano-structured graphene material."

If adopted by industry, Asst Prof Wang expects that cost of manufacturing imaging sensors to fall -- eventually leading to cheaper cameras with longer battery life.

How the Graphene nanostructure works

Asst Prof Wang came up with an innovative idea to create nanostructures on graphene which will "trap" light-generated electron particles for a much longer time, resulting in a much stronger electric signal. Such electric signals can then be processed into an image, such as a photograph captured by a digital camera.

The "trapped electrons" is the key to achieving high photoresponse in graphene, which makes it far more effective than the normal CMOS or CCD (charge-coupled device) image sensors, said Asst Prof Wang. Essentially, the stronger the electric signals generated, the clearer and sharper the photos.

"The performance of our graphene sensor can be further improved, such as the response speed, through nanostructure engineering of graphene, and preliminary results already verified the feasibility of our concept," Asst Prof Wang added.

This research, costing about $200,000, is funded by the Nanyang Assistant Professorship start-up grant and supported partially by the Ministry of Education Tier 2 and 3 research grants.

Development of this sensor took Asst Prof Wang a total of 2 years to complete. His team consisted of two research fellows, Dr Zhang Yongzhe and Dr Li Xiaohui, and four doctoral students Liu Tao, Meng Bo, Liang Guozhen and Hu Xiaonan, from EEE, NTU. Two undergraduate students were also involved in this ground-breaking work.

Asst Prof Wang has filed a patent through NTU's Nanyang Innovation and Enterprise Office for his invention.

The next step is to work with industry collaborators to develop the graphene sensor into a commercial product.

Four fighters die battling huge Houston fire

Fossilized sediment from New Jersey's salt marshes contains evidence of a migrating coast line. For some 2,000 years, up until the dawn of our modern warming era around 1900, the sea level off of what's now New Jersey was rising by about one to two millimeters a year, with the coast itself imperceptibly creeping inland. Today, the sea level is rising by three to five millimeters a year.
