Seau Suffered Brain Disease From NFL Hits: Study

A team of scientists who analyzed the brain tissue of renowned NFL linebacker Junior Seau after his suicide last year have concluded the football player suffered a debilitating brain disease likely caused by two decades worth of hits to the head, researchers and his family exclusively told ABC News and ESPN.

In May, Seau, 43 -- football's monster in the middle, a perennial all-star and defensive icon in the 1990s whose passionate hits made him a dominant figure in the NFL -- shot himself in the chest at his home in Oceanside, Calif., leaving behind four children and many unanswered questions.

Seau's family donated his brain to neuroscientists at the National Institutes for Health who are conducting ongoing research on traumatic brain injury and football players.

A team of independent researchers who did not know they were studying Seau's brain all concluded he suffered from chronic traumatic encephalopathy (CTE), a degenerative disease typically caused by multiple hits to the head.

"What was found in Junior Seau's brain was cellular changes consistent with CTE," said Dr. Russell Lonser, chairman of the Department of Neurological Surgery at Ohio State University, who led the study of Seau's brain while he was at NIH.

Patients with CTE, which can only be diagnosed after death, display symptoms "such as impulsivity, forgetfulness, depression, [and] sometimes suicidal ideation," Lonser said.

Seau's family described to ABC News and ESPN a long descent into depression in the years prior to his death.

Gina Seau, his ex-wife with whom he remained close following their divorce, said the linebacker had difficulty sleeping and became withdrawn and "detached emotionally" from his children. In one exchange, he described his mood as "low" and "dark."

"A lot of things, towards the end of his life, patterns that we saw and things that worried us, it makes sense now," she said of the diagnosis.

The night before his death, Seau sent a text message to his ex-wife and children in which he simply wrote, "I love you." They were the last words anyone would hear from him.

More than 30 NFL players have in recent years been diagnosed with CTE, a condition once known as "punch drunk" because it affected boxers who had taken multiple blows to the head. Last year, 4,000 retired players joined a class-action lawsuit against the league over its alleged failure to protect players from brain injuries.

The NFL has said it did not intentionally hide the dangers of concussions from players and is doing everything it can now to protect them.

Gina Seau said she and her ex-husband expected physical injuries from playing professional football but never thought "you're putting your brain and your mental health at a greater risk."

Junior Seau, she said, was never formally diagnosed with a concussion but routinely complained of symptoms associated with concussions after receiving hits to the head during games and in practices in 20 seasons in the NFL.

"The head-to-head contact, the collisions are just, they're out of control," Gina Seau said.

"He was a warrior and he loved the game," she added. "But ... I know that he didn't love the end of his life."

For the Seaus, football gave them everything and, they believe, has now taken it all away. They understand its attraction and, all too well, its routine danger.

"I think it's a gamble," Gina Seau said. "Just be extremely aware of what could potentially happen to your life."

None of the Seau children play football anymore and their mother is glad of that.

"It's not worth it for me to not have a dad," said one of the Seaus' sons, Tyler Seau, 23. "So, to me, it's not worth it."

US no longer lists satellites as weapons

Satellites are no longer weapons, according to a change in US anti-arms trafficking law. The move gives hope to commercial spaceflight companies wanting to sell their technology on the global market rather than just within the US. However, the focus on Earth-orbiting craft means deep-space missions could still be hampered by onerous security laws.

On 3 January, President Barack Obama authorised a revision of the International Traffic in Arms Regulations law. Since 1999, ITAR listed US satellites and related technology as munitions with strict limits on exports to foreign powers – much to the annoyance of satellite makers. They say they cannot earn what they need to stay innovative without selling advanced technology abroad.

The updated law takes Earth-orbiting satellites and technologies off the list, although the president retains veto power, and the ruling doesn't apply to some countries, including China, Iran and North Korea.

Free space

Alex Saltman of the Commercial Spaceflight Federation in Washington DC hopes the relaxation of rules will in future be extended to other space-tourism equipment such as crew capsules, which remain restricted by ITAR.

"Space technologies that in the past had primarily military uses, or which had mixed military and civilian uses, are becoming primarily commercial and therefore should be regulated as such," says Saltman. "While there is no immediate effect – there is nothing that is allowed now that was not allowed a month ago – we are a big step down the road toward loosening restrictions."

The new rules should also allow US students who aren't citizens to access computer data and documents from US aerospace companies, which they had been denied until now. So says Sara Seager, a planetary scientist at the Massachusetts Institute of Technology, whose students design and build small satellites called CubeSats.

But major issues remain, Seager says, such as what will happen to international collaborations on more far-ranging probes. For instance, her students are designing instruments for the OSIRIS-REx mission to an asteroid, and it's unclear how the new rules might impact her non-US students.

"Why did they focus on satellites that orbit Earth and not spacecraft that go beyond Earth?" she says. "It's not clear whether the government can fix this language before it is written up into regulations."

S'pore retail investors optimistic about outlook: survey

SINGAPORE: Singapore retail investors are optimistic about their investment outlook for the next six months, according to a survey released on Wednesday by J P Morgan Asset Management.

According to the report, the J P Morgan Investor Confidence Index increased by 5 points to 106 in the latest survey, conducted between November 21 to December 7 2012.

This is a marked increase from one year ago, where the index was 86.

The increased confidence was boosted by expectations of an improved global economic environment, with 42 per cent of respondents indicating that they are likely to increase their investments in the next six months.

"The latest results demonstrate that Singapore investor confidence continues to improve," said Mr Andrew Creber, Head of Singapore Business, J P Morgan Asset Management.

"This is no doubt influenced by the progress we have seen over the past six months, where the risk of a financial meltdown in Europe was largely reduced. The Chinese economy is steadily recovering. In the US, despite the ongoing political tug-of-war over public finance, the restoration of household balance sheets and an improvement in the housing market is taking place," he added.

Confidence is also returning to affluent investors.

Investors with investable assets of S$500,000 and above were markedly more optimistic than investors with less investable assets, hitting a confidence level of 119, an increase of 17 points from June 2012.

Meanwhile, mutual fund investors have shown an increasing preference for multi asset/balanced funds, with those surveyed increasing their weighted allocation up by 7 per cent to 47 per cent for their mutual fund portfolio.

"It is important for investors to remain diversified to maintain stability in their portfolios," said Mr Creber.

The J P Morgan Investor Confidence Index is derived from a scoring of investor responses to a series of questions on their outlook for the Straits Times Index (STI), local and global economic and investment environments, and appreciation in their investment portfolio.

An index level of 100 is neutral, while 200 is extremely optimistic while zero is extremely pessimistic.

Kensington has launched a system called Proximo that it promises will alert people when items like keys and iPhones are lost or stolen.

The Proximo kit consists of an iPhone app, a key fob for a keychain, and a third device to track something else like a backpack or
car, the company announced at
CES. If the items get too far apart -- people can specify the exact distances, which are measured wirelessly using BlueTooth -- they sound an alarm.

The fobs and app each come with buttons that triggers an audible alarm from a paired device to help locate it. And the app offers a map for GPS-based tracking for devices that are out of range.

The kit costs $60, and additional $25 tags can be purchased to track up to five devices with the app.

Also at CES, Kensington announced a few other accessories:

• The $50 TriFold Folio
iPad case for fourth-generation iPads, with a protective shell back and a three-fold front cover that can serve as a stand.

• The $35 PowerBolt 4.2 Dual Fast Charge car charger with dual 2.1-watt USB charging ports and two detachable older-style iPhone charging cables. Those with iOS devices using the newer Lightning port will have to use their own cables.

• The $30 PowerBolt 2.1 Fast Charge car charger with a single attached Lightning cable.

• The $90 Contour Overnight backpack that features a laptop compartment that can be unzipped and laid flat for easier trips through airport security. It's got a larger capacity than earlier models of the company's Contour packpack models.

Pictures: Wildfires Scorch Australia Amid Record Heat

Photograph by Jo Giuliani, European Pressphoto Agency

Smoke from a wildfire mushrooms over a beach in Forcett, Tasmania, on January 4. (See more wildfire pictures.)

Wildfires have engulfed southeastern Australia, including the island state of Tasmania, in recent days, fueled by dry conditions and temperatures as high as 113ºF (45ºC), the Associated Press reported. (Read "Australia's Dry Run" inNational Geographic magazine.)

No deaths have been reported, though a hundred people are unaccounted for in the town of Dunalley, where the blazes destroyed 90 homes.

"You don't get conditions worse than this," New South Wales Rural Fire Service Commissioner Shane Fitzsimmons told the AP.

"We are at the catastrophic level, and clearly in those areas leaving early is your safest option."

Dead Lotto Winner's Wife Seeks 'Truth'

The wife of a $1 million Chicago lottery winner who died of cyanide poisoning told ABC News that she was shocked to learn the true cause of his death and is cooperating with an ongoing homicide investigation.

"I want the truth to come out in the investigation, the sooner the better," said Shabana Ansari, 32, the wife of Urooj Khan, 46. "Who could be that person who hurt him?

"It has been incredibly hard time," she added. "We went from being the happiest the day we got the check. It was the best sleep I've had. And then the next day, everything was gone."

Ansari, Khan's second wife, told the Chicago Sun-Times that she prepared what would be her husband's last meal the night before Khan died unexpectedly on July 20. It was a traditional beef-curry dinner attended by the married couple and their family, including Khan's 17-year-old daughter from a prior marriage, Jasmeen, and Ansari's father. Not feeling well, Khan retired early, Ansari told the paper, falling asleep in a chair, waking up in agony, then collapsing in the middle of the night. She called 911.

Khan, an immigrant from India who owned three dry-cleaning businesses in Chicago, won $1 million in a scratch-off Illinois Lottery game in June and said he planned to use the money to pay off his bills and mortgage, and make a contribution to St. Jude Children's Research Center.

"Him winning the lottery was just his luck," Ansari told ABC News. "He had already worked hard to be a millionaire before it."

Jimmy Goreel, who worked at the 7-Eleven store where Khan bought the winning ticket, described him to The Associated Press as a "regular customer ... very friendly, good sense of humor, working type of guy."

Khan's unexpected death the month after his lottery win raised the suspicions of the Cook County medical examiner. There were no signs of foul play or trauma so the death initially was attributed to arteriosclerotic cardiovascular disease, which covers heart attacks, stroke or ruptured aneurysms. The medical examiner based the conclusion on an external exam -- not an autopsy -- and toxicology reports that indicated no presence of drugs or carbon monoxide.

Khan was buried at Rosehill Cemetery in Chicago.

However, several days after a death certificate was issued, a family member requested that the medical examiner's office look further into Khan's death, Cook County Medical Examiner Stephen Cina said. The office did so by retesting fluid samples that had been taken from Khan's body, including tests for cyanide and strychnine.

When the final toxicology results came back in late November, they showed a lethal level of cyanide, which led to the homicide investigation, Cina said. His office planned to exhume Khan's body within the next two weeks as part of the investigation.

Melissa Stratton, a spokeswoman for the Chicago Police Department, confirmed it has been working closely with the medical examiner's office. The police have not said whether or not they believe Khan's lottery winnings played a part in the homicide.

Khan had elected to receive the lump sum payout of $425,000, but had not yet received it when he died, Ansari told the AP, adding that the winnings now are tied up as a probate matter.

"I am cooperating with the investigation," Ansari told ABC News. "I want the truth to come out."

Authorities also have not revealed the identity of the relative who suggested the deeper look into Khan's death. Ansari said it was not her, though she told the AP she has subsequently spoken with investigators.

"This is been a shock for me," she told ABC News. "This has been an utter shock for me, and my husband was such a goodhearted person who would do anything for anyone. Who would do something like this to him?

"We were married 12 years [and] he treated me like a princess," she said. "He showered his love on me and now it's gone."

Tony Fadell: From iPhones to sexing up thermostats

After quitting Apple, the tech guru behind the iPod wanted to revolutionise our homes – starting with the humble thermostat

After you left Apple, you developed a "smart" thermostat. Was that always your plan?
Not at all! The plan was to retire with my wife, who also worked for Steve [Jobs], and spend time with our children. We didn't see them because we were working so madly at Apple. We wanted to build a house in Lake Tahoe. I wanted to design the greenest, most connected house that I could. That's when I found out about the thermostat problem. These devices had not seen innovation in 30 years. They were the same as the ones our parents had. I wanted something that was very different.

Your solution was the NEST. Tell me about it
It uses algorithms and sensors to remember the temperatures you like, create a custom schedule for your home and turn itself down when you are away. And you can use your smartphone, tablet or computer to control it remotely. We call it the thermostat for the iPhone generation. It has a big dial, not fiddly buttons.

Did Steve Jobs have any input?
I was going to talk to Steve about it. He knew we were working on something, but he didn't know what. When it was time to show him, he said he couldn't do it. Unfortunately, he died just a few weeks later, before he could see it.

Is the NEST just the start of a range of smart-home devices?
Absolutely. But if you look at what we did at Apple after the iPod came out, it took us five years to start thinking about the iPhone and two more years to finally ship it. I would love to make more devices, but our goal is to make the NEST successful first.

Who would have believed the iPod could turn into the iPhone, then the iPad?
Even I wondered how many people would buy an iPad. But you have to be at the right place in the cultural time. We plan a similar trajectory with the NEST, with the ways that emerging behaviours can happen in the home through interconnected devices. You can't start with all of these things at once because people's minds get blown. You start with very simple things, simple concepts, and then you can build on them.

Will people have to continually upgrade their thermostats, as they do with cellphones?
Unlike a cellphone, you're not going to change the NEST every 18 months! They are supposed to hang on your wall for 10 to 15 years. Our goal is to continue to improve it via software, and we have built tonnes of extra capability into this device to allow that to happen. For example, we have a new update that gives an energy report - it shows how you're doing compared with last month, and even compares you to your neighbours.

Was it your aim to raise awareness of the energy we waste heating our homes?
The NEST starts people thinking about how they're using energy in the home. But it's also a great party trick. You get people whipping out their phones and saying "Check out my NEST at home! Watch, I'm going to freeze my wife!"

Police fire plastic bullets in Northern Ireland riots

BELFAST, United Kingdom: Police in Northern Ireland fired plastic bullets and water cannon at protesters in the capital Belfast late Monday after coming under a hail of petrol bombs, bricks and stones for a fifth night.

Rioters in the east of the city used weapons including hatchets and sledge hammers to attack police and their vehicles, the Police Service of Northern Ireland (PSNI) said.

Pro-British protesters have taken to the streets of Belfast almost every night since December 3, when the city council announced that it would no longer fly the British flag all year round at the City Hall.

The decision sparked riots at the start of December which gave way to largely peaceful protests, but the violence has flared again since the start of the new year.

Britain's Northern Ireland minister Theresa Villiers said the province was being "held to ransom" by the protesters and called for an end to their demonstrations, including peaceful rallies that have blocked traffic for weeks.

"It's not acceptable that those who say they are defending a Union flag are actually doing it by hurling bricks and petrol bombs at police. It's disgraceful, frankly," she told BBC radio.

She added that the protests were doing "huge damage to Northern Ireland's image abroad".

The flag ruling has raised tensions in the British province between loyalists - who want to maintain the links to Britain and are mostly Protestant - and largely Catholic republicans who want a united Ireland.

Northern Ireland's chief police officer Matt Baggott on Monday accused the paramilitary Ulster Volunteer Force, which murdered more than 500 people during the province's 30-year sectarian conflict, of whipping up the disorder.

"Senior members of the UVF in east Belfast as individuals have been increasingly orchestrating some of this violence," he told a press conference.

"That is utterly unacceptable and is being done for their own selfish motives."

On Monday, police battled to separate a crowd of around 250 loyalists from some 70 Catholic republicans, who hurled missiles including bottles at the protesters.

Around 1,000 loyalists had earlier staged a peaceful demonstration outside the City Hall as councillors held their first meeting since their decision to take the flag down.

More than 60 police officers have been injured and over 100 people arrested since the disorder began at the start of December.

The PSNI said four people had been charged in connection with Monday night's disorder and were due to appear in court on Tuesday.

Politicians from both sides have received death threats in recent weeks, but lawmakers from all major parties have insisted that the spate of violence does not pose a serious threat to Northern Ireland's peace process.

Some 3,000 people were killed in the three decades of sectarian bombings and shootings in Northern Ireland known as "The Troubles".

A 1988 peace agreement brought an end to most of the violence and led to the creation of a power-sharing government between Protestants and Catholics, but sporadic bomb threats and murders by dissident republicans continue.

Loyalists see the council's decision to remove the flag for most of the year as an attack on their British identity and an unacceptable concession to republicans.

The flag will only be flown on a maximum of 17 designated days including the birthdays of members of the British royal family -- the first of which falls on Wednesday with the birthday of Prince William's wife Catherine.

Across the border in the Republic of Ireland, police are assessing the risk posed by a planned loyalist protest against the flag ruling in Dublin on Saturday.

The last major loyalist demonstration in the Irish capital sparked rioting and looting in 2006.

Primitive and Peculiar Mammal May Be Hiding Out in Australia

It’d be hard to think of a mammal that’s weirder than the long-beaked, egg-laying echidna. Or harder to find.

Scientists long thought the animal, which has a spine-covered body, a four-headed penis, and a single hole for reproducing, laying eggs, and excreting waste, lived only in New Guinea. The population of about 10,000 is critically endangered. Now there is tantalizing evidence that the echidna, thought to have gone extinct in Australia some 10,000 years ago, lived and reproduced there as recently as the early 1900s and may still be alive on Aussie soil.

The new echidna information comes from zoologist Kristofer Helgen, a National Geographic emerging explorer and curator of mammals at the Smithsonian Institution. Helgen has published a key finding in ZooKeys confirming that a skin and skull collected in 1901 by naturalist John T. Tunney in Australia is in fact the western long-beaked echidna, Zaglossus bruijnii. The specimen, found in the West Kimberley region of Western Australia, was misidentified for many years.

(More about echidnas: Get to know this living link between mammals and reptiles.)

Helgen has long been fascinated by echidnas. He has seen only three in the wild. “Long-beaked echidnas are hard to get your hands on, period,” he said. “They are shy and secretive by nature. You’re lucky if you can find one. And if you do, it will be by chance.” Indeed, chance played a role in his identification of the Australian specimen. In 2009, he visited the Natural History Museum of London, where he wanted to see all of the echidnas he could. He took a good look in the bottom drawer of the echidna cabinet, where the specimens with less identifying information are often stored. From among about a dozen specimens squeezed into the drawer, he grabbed the one at the very bottom.

(Related from National Geographic magazine: “Discovery in the Foja Mountains.”)

“As I pulled it out, I saw a tag that I had seen before,” Helgen said. “I was immediately excited about this label. As a zoologist working in museums you get used to certain tags: It’s a collector’s calling card. I instantly recognized John Tunney’s tag and his handwriting.”

John Tunney was a well-known naturalist in the early 20th century who went on collecting expeditions for museums. During an Australian expedition in 1901 for Lord L. Walter Rothschild’s private museum collection, he found the long-beaked echidna specimen. Though he reported the locality on his tag as “Mt Anderson (W Kimberley)” and marked it as “Rare,” Tunney left the species identification field blank. When he returned home, the specimen was sent to the museum in Perth for identification. It came back to Rothschild’s museum identified as a short-beaked echidna.

With the specimen’s long snout, large size, and three-clawed feet, Helgen knew that it must be a long-beaked echidna. The short-beaked echidna, still alive and thriving in Australia today, has five claws, a smaller beak, and is half the size of the long-beaked echidna, which can weigh up to 36 pounds (16 kilograms).

As Helgen began tracing the history and journey of the specimen over the last century, he crossed the path of another fascinating mind who had also encountered the specimen. Oldfield Thomas was arguably the most brilliant mammalogical taxonomist ever. He named approximately one out of every six mammals known today.

Thomas was working at the Natural History Museum in London when the Tunney echidna specimen arrived, still misidentified as a short-beaked echidna. Thomas realized the specimen was actually a long-beaked echidna and removed the skull and some of the leg bones from the skin to prove that it was an Australian record of a long-beaked echidna, something just as unexpected then as it is now.

No one knows why Thomas did not publish that information. And the echidna went back into the drawer until Helgen came along 80 years later.

As Helgen became convinced that Tunney’s long-beaked echidna specimen indeed came from Australia, he confided in fellow scientist Mark Eldridge of the Australian Museum about the possibility. Eldridge replied, “You’re not the first person who’s told me that there might be long-beaked echidnas in the Kimberley.” (That’s the Kimberley region of northern Australia.) Scientist James Kohen, a co-author on Helgen’s ZooKeys paper, had been conducting fieldwork in the area in 2001 and spoke to an Aboriginal woman who told him how “her grandmothers used to hunt” large echidnas.

This is “the first evidence of the survival into modern times of any long-beaked echidna in Australia,” said Tim Flannery, professor at Macquarie University in Sydney. “This is a truly significant finding that should spark a re-evaluation of echidna identifications from across northern Australia.”

Helgen has “a small optimism” about finding a long-beaked echidna in the wild in Australia and hopes to undertake an expedition and to interview Aboriginal communities, with their intimate knowledge of the Australian bush.

Though the chances may be small, Helgen says, finding one in the wild “would be the beautiful end to the story.”

Giffords, Kelly Launch Initiative to Curb Gun Violence

After she was gravely wounded by gunfire two years ago in Tucson, Ariz., former Rep. Gabrielle Giffords and her husband, Mark Kelly, imagined a life out of the public eye, where she would continue therapy surrounded by the friends, family and the Arizona desert she loves so much.

Gabby Giffords and Mark Kelly Speak Exclusively to Diane Sawyer

But after the slaughter of 20 first-graders and six adults at Sandy Hook Elementary School in Newtown, Conn., last month, Giffords and Kelly knew they couldn't stay silent.

"Enough," Giffords said.

The couple marked the second anniversary of the Tucson shooting by sitting down with Diane Sawyer to discuss their recent visit to Newtown and their new initiative to curb gun violence, "Americans for Responsible Solutions."

"After the shooting in Tucson, there was talk about addressing some of these issues, [and] again after [a movie theater massacre in] Aurora," Colo., Kelly said. "I'm hopeful that this time is different, and I think it is. Twenty first-graders' being murdered in their classrooms is a very personal thing for everybody."

During their trip to Newtown, Giffords and Kelly met with families directly affected by the tragedy.

"[The] first couple that we spoke to, the dad took out his cell phone and showed us a picture of his daughter and I just about lost it, just by looking at the picture," Kelly said. "It was just very tough and it brought back a lot of memories about what that was like for us some two years ago."

Full Coverage: Tragedy in Newtown

"Strength," Giffords said she told the families in Newtown.

"Gabby often told them, 'You got to have strength. You got to fight for something,'" Kelly said.

The innocent faces of the children whose lives were abruptly taken reminded the couple, they said, of 9-year-old Christina-Taylor Green, the youngest victim to die in the Tucson shooting at a Giffords constituent event.

"I think we all need to try to do something about [gun violence]," Kelly said. "It's obvious to everybody we have a problem. And problems can be solved."

Giffords, Kelly Call for 'Common Sense' Solutions

Giffords, 42, and Kelly, 48, are both gun owners and supporters of the 2nd Amendment, but Kelly had strong words for the National Rifle Association after the group suggested the only way to stop gun violence is to have a "good guy with a gun."

There was a good guy with a gun, Kelly said, the day Jared Loughner shot Giffords and 18 other people, six fatally, at her "Congress on Your Corner" event.

"[A man came out] of the store next door and nearly shot the man who took down Jared Loughner," Kelly said. "The one who eventually wrestled [Loughner] to the ground was almost killed himself by a good guy with a gun, so I don't really buy that argument."

Instead, Giffords and Kelly are proposing "common sense" changes through "Americans for Responsible Solutions."
