Fergie weighs up van Persie's Man United debut

Sir Alex Ferguson will wait until the last minute before deciding whether new striker Robin van Persie is fit enough to make his debut in Manchester United's Premier League opener at Everton on Monday.

Van Persie, signed for ?24 million from Arsenal, rushed back from international duty with Holland in midweek to undergo a medical in Manchester that went into the early hours of Friday before completing the most eye-catching Premier League transfer of the year.

After such a hectic schedule, and just a handful of training sessions with his new team-mates, United manager Ferguson is uncertain if he should throw van Persie straight into his starting line-up at Goodison Park.

"He hasn't played much. We are going to assess him the next couple of days and chat with him, see how he feels himself," Ferguson said.

"Adrenalin will help, if I choose to start him, but I think it's important he had a training session on Friday morning and hopefully the weekend will give me a good idea on whether he should start or I should put him on the bench."

Van Persie's arrival gives Ferguson, who could already call on Wayne Rooney, Javier Hernandez and Danny Welbeck, an impressive collection of attacking talent and the Scot believes Welbeck is just one player who will benefit from playing alongside such a world-class performer.

"It's been a long haul but the point I'm making about maturity is we needed a finished player," Ferguson said.

"(Paul) Scholes and (Ryan) Giggs are coming to the end and I need mature top players to replace them.

"The young ones don't have what Scholes and Giggs do at the moment and that's very important.

"We have had several players who have been that sort of catalyst, starting with (Eric) Cantona, I don't think we're short of all that, I think we were still capable of winning the title without Robin but he gives us a sort of certainty for the future.

"You always learn from great players, if you look at what Cantona did, he was a tremendous teacher for the all the young players and I think Danny will welcome that.

"He will learn he won't play every week because he will get little niggles and strains, but when he's 23 or 24 he'll be a fantastic player and will learn from the other strikers here.

"We've got a great combination of strikers now, it will be difficult for me but it's better to have another great player rather than worrying if you've got the right player."

In the eyes of one rival manager, at least, the van Persie signing makes United strong favourites for the title although Ferguson was placing little credibility in the claims of Roberto Mancini, manager of defending champions Manchester City, who said precisely that.

"We are favourites every week according to him, does he not realise he's got a decent team himself," joked Ferguson.

"That rivalry has been going on 100 years, not just last year, neighbours are neighbours and these games never change. But if you ask me who I think will be our biggest threat I would say Man City without question."

Everton manager David Moyes believes van Persie is a "seriously good" signing for United but does not intend to make it a debut to remember for the 29-year-old Dutchman.

Moyes is determined his players make a winning start to the campaign after losing their previous four opening day games.

"I think United have made some good signings, bought some young players and bought one who is maybe a little bit older than they normally do," Moyes said.

"But he's a seriously good player who you would expect will make a big difference. He will be a big help to an already good side.

"But we will be ready for Manchester United. We want to get the season off on the right note."

Quarterbacks? energy needs to be contagious

Johnny Manziel looked comfortable in his first weekend scrimmage since being named Texas A&M?s starting quarterback, but enough other players looked a little too comfortable Saturday at Kyle Field, enough so to irk first-year head coach Kevin Sumlin.

Manziel opened the intrasquad scrimmage by leading the Aggies on a 14-play, 66-yard drive that ended in a missed 49-yard field goal attempt by fellow redshirt freshman Taylor Bertolet. Manziel completed 3 of 6 passes on the drive for 14 yards and added a nifty 11-yard run up the middle on a possession that started at the offense?s 3-yard line.

?What we?re trying to do there is get two first downs and turn the field over if you?ve got to punt it,? Sumlin said.

The next possession from the 3 led to a quick touchdown thanks to running back Trey Williams? 56-yard run to the 2. Sophomore linebacker Justin Bass caught Williams from behind after Williams cut back to avoid junior defensive back Johntel Franklin.

Williams had three other carries for 15 yards on the drive and ended with 93 yards on nine carries.

Sumlin playfully said he?d give the true freshman grief for getting caught from behind, but he won?t be joking with the players who pulled down the team?s overall performance Saturday.

?I was disappointed with the amount of energy that was out there,? Sumlin said. ?We?re not a good enough team to go out and just play football and go through motions. We have to play with energy. I didn?t see that today like we have been.?

Sumlin said he was anxious to see how his team would handle the scrimmage after eight practices in five days including a couple that lasted almost 2 1/2 hours.

?We?ve got to fight through that,? Sumlin said. ?That?s where you have to be a tough team physically and mentally. That?s the reason we did that, to let them know you can do it. But you?ve got to create your own energy, and our team didn?t do that today and that?s a learning experience. You can?t play this game at a high level without emotion, and we lacked that today.?

The nine penalties also bothered Sumlin, but he said he was pleased with the quarterbacks.

Manziel had a 30-yard pass to senior Uzoma Nwachukwu that led to a 4-yard TD run by Trey Williams. Sophomore Jameill Showers guided a 97-yard drive that ended with a 2-yard touchdown by Brandon Williams, and sophomore Matt Joeckel threw a 44-yard touchdown pass to junior transfer Derel Walker.

Joeckel had the best stats of the quarterbacks ? 5 of 10 for 128 yards. Manziel completed 6 of 10 for 51 yards with an interception.

?They?re competitors,? Sumlin said. ?They understand only one can play, but as you can see they?re all still going to continue to get better because you never know when your chance is going to come.

?We?ve got a couple of positions out there right now that if they were competing at the level the quarterbacks are competing, we?d be all right. We?ve got some guys [who] have accepted their roles, and that?s disappointing.?

The defense forced two turnovers.

Sophomore defensive back Deshazor Everett had a big hit to prevent freshman wide receiver Sabian Holmes from making a catch near the end zone with senior linebacker Jonathan Stewart grabbing the deflected pass for an interception. And redshirt freshman defensive back Sam Moeller knocked the ball from Brandon Williams on fourth-and-goal from the 1 with sophomore defensive back Floyd Raven Sr. recovering the fumble in the end zone.

?[Brandon Willliams] plays so hard. He veered back into a guy, trying to run him over,? Sumlin said. ?He didn?t need to do that. All these are learning situations we try to get guys in.

?
Missing players: Senior safety Steven Campbell, senior running back Christine Michael, junior defensive lineman Kirby Ennis, sophomore offensive lineman Cedric Ogbuehi, sophomore running back Tra Carson and true freshman center Mike Matthews did not play among others. Senior wide receiver Ryan Swope saw little action, catching one pass.

?
Tough day for some: ?The goal today was to scrimmage the backups, and what you got was backup football,? Sumlin said. ?You don?t know what the hell?s gonna happen. You throw it ... sometimes we catch it, sometimes we don?t. A guy catches it and [he] gets hit. That?s the reason why they?re backups. That?s why we?re trying to develop those guys and see who?s going to come on.?

?
NOTES ? Sumlin said he expects to hear from the NCAA this week whether sophomore transfer running back Brandon Williams will be able to play this season or have to sit out. ? Junior walk-on wide receiver Gaston Lamascus from Navasota caught a 50-yard pass from Joeckel. ? A&M will not practice Sunday. ? Former head coach R.C. Slocum and recently retired athletics director Bill Byrne attended the game.

Police race to find Ian Brady letter before his victim Keith's mother dies of cancer

WINNIE JOHNSON has never given up hope of finding her child, who was snatched by Moors Murderers Ian Brady and Myra Hindley.

POLICE are racing against time to find a letter which could reveal where Keith Bennett is buried before his mum
dies of cancer.

Winnie Johnson has never given up hope of finding her child, who was snatched by Moors Murderers Ian Brady and Myra Hindley.

She is seriously ill in a hospice and sources say she has ?days rather than weeks to live?.

Now Brady?s mental health advocate Jackie Powell, 49, has claimed she received a sealed envelope thought to contain details of Keith?s final resting place.

She said the 74-year-old killer insisted it could not be opened until after his death ? at which point, the contents should be passed to Winnie.

It is understood that Powell said she returned the letter to Brady.

Police arrested her on suspicion of preventing a lawful burial but she was later freed on bail.

Myra Hindley
Myra Hindley

Last night, officers were searching through hundreds of documents in a bid to find the letter, after it was claimed it existed ten years ago.

Yesterday, Powell?s former husband, Stephen Powell, 52, said he had known about the letter for the past decade.

He said: ?I did tell the authorities 10 years ago that this letter existed.?

Police have also searched Brady?s room at Ashworth Hospital in Merseyside, where he is said to keep a battered 1960s-style suitcase containing papers.

An insider said:?This case has become legendary amongst staff at Ashworth.

?A clinical liason member of staff was able to look in it but, incredible though it may seem, there was some rule that stopped police search teams seeing what was kept inside.

?Everybody was told that whatever is kept within the case will not be seen until after Brady?s death ? it was supposedly legal letters, documents and possibly even photographs.?

Police fear they may not find the letter before Winnie succumbs to her illness ? and some are sceptical it even exists.

A source said: ?We took everything from Powell?s house that wasn?t nailed down but so far, we have not found this letter. We may come across it in coming days but, if I had to make a bet, I would say there is a chance we may never find it.?

Officers decided not to upset Winnie by telling her of the new claims, although her son Alan, 56 ? Keith?s brother ? was informed.

Powell refused to comment on the case yesterday at her home in south Wales.

Speaking from an upstairs window she said: ?Just leave me alone. I don?t want to know.?

Winnie?s solicitor, John Ainley, said: ?Brady is very manipulative and wants a sense of power by retaining this information until after his death. The family find it hard to believe this letter exists.?

Mets Vs. Nationals Preview: Gio Gonzalez Starts For Washington In Rubber Game

In a pitchers' duel between the Washington Nationals' Edwin Jackson and the New York Mets' Jon Niese, the Nats fell by a score of 2-0 Saturday on a lone Ike Davis home run in the seventh. With this home series now knotted up, the Nationals will turn to trusty lefty Gio Gonzalez (15-6, 3.29 ERA) against New York's right handed-rookie Jeremy Hefner (2-4, 4.76 ERA) to win their last home series against the Mets for the 2012 season.

Gonzalez has been an excellent complement to Nationals' ace Stephen Strasburg since being acquired from Oakland -- so excellent in fact, that Gonzalez is but one win away from becoming the winningest single season pitcher for the Nationals' franchise since the move from Montreal in 2005. If the Nationals are to not only win today, but also to maintain their hold of the NL East lead without the to-be-shutdown arm of of Strasburg, the All-Star Gonzalez will have to both meet and exceed what is expected of him by fans and coaches.

Also with a win today, Gonzalez would tie Cincinnati's Johnny Cueto and Tampa Bay's David Price for the Major League lead in wins.

Gonzalez's last outing against New York was a successful one, as he led Washington to a 5-2 victory over R.A. Dickey at Citi Field with a seven-inning, two-hit performance which yielded one unearned run.

Right fielder Jayson Werth and shortstop Ian Desmond are expected to miss Sunday's contest with a reported "day off." More lineup information, including complete lineups of this rubber match, will be provided as soon as they are made available.

Apple Hacker Uncovers SMS Security Hole in iPhone

A French iOS security researcher and jailbreak hacker known as pod2g has uncovered a security flaw that makes the iPhone susceptible to text message spoofing.

According to pod2g's iOS blog, the flaw has existed in the iPhone ever since its release in 2007 and continues to exist in the latest iOS 6 beta 4. "Apple: please fix before the final release," says pod2g on its blog.

"Found a heavy SMS flaw in iOS. Doesn't involve code execution but still severe," says pod2g's tweet.

According to pod2g, the flaw could allow malicious users to spoof text messages making the receiver think that the message has come from a trusted party.

Generally, an SMS text is made up of bytes of data exchanged among two devices; the specific carrier helps in transferring the information. The text is converted into Protocol Description Unit (PDU) and then moved to baseband for delivery. ?

In the text payload, the User Data Header (UDH) contains several advanced features, while not all devices are compatible. One of the features will reportedly allow the user to modify the "reply address of the text". In case the receiver's device is compatible and if he/she wishes to respond to the text then he/she will respond to the original number, instead of the specified number.

Not all carriers check this part of the message that will result in changing the number. "In a good implementation of this feature, the receiver would see the original phone number and the reply-to one. On iPhone, when you see the message, it seems to come from the reply-to number, and you lose track of the origin," writes pod2g.

pod2g notes some major examples in regard to the security issue:

  • Pirates might send a message which looks as if coming from a bank, asking the receiver to give his/her confidential information or may direct him to a dedicated website.
  • A malicious user might send a spoofed message to a recipient's device in order to create false evidence.

"Now you are alerted. Never trust any SMS you receive on your iPhone at first sight," pod2g concludes.

Beautiful Dwarf Galaxy DDO 190 Imaged in Detail

Using the NASA/ESA Hubble Space Telescope, a team of astronomers recently has snapped a sharp and very clear image of the dwarf galaxy DDO 190, whose name comes from the David Dunlap Observatory. The latter manages the catalog in which this object is included.

Scientists classify DDO 190 as a dwarf irregular galaxy. It lies around 9 million light-years away from Earth, which basically puts it in our backyard, astronomically speaking. The object is part of the loosely bound Messier 94 group of galaxies.

The members of this galaxy cluster do not interact gravitationally too much, experts say. Though part of a larger structure, DDO 190's closest neighbor, the equally-dwarf galaxy DDO 187, is located at least 3 million light-years away.

?In contrast, many of the Milky Way?s companion galaxies, such as the Large and Small Magellanic Clouds, reside within a fifth or so of that distance, and even the giant spiral of the Andromeda Galaxy is closer to the Milky Way than DDO 190 is to its nearest neighbor,? NASA experts say.

Brain's mysterious switchboard operator revealed

ScienceDaily (Aug. 17, 2012) ? A mysterious region deep in the human brain could be where we sort through the onslaught of stimuli from the outside world and focus on the information most important to our behavior and survival, Princeton University researchers have found.

The researchers report in the journal Science that an area of our brain called the pulvinar regulates communication between clusters of brain cells as our brain focuses on the people and objects that need our attention. Like a switchboard operator, the pulvinar makes sure that separate areas of the visual cortex -- which processes visual information -- are communicating about the same external information, explained lead author Yuri Saalmann, an associate research scholar in the Princeton Neuroscience Institute (PNI). Without guidance from the pulvinar, an important observation such as an oncoming bus as one is crossing the street could get lost in a jumble of other stimuli.

Saalmann said these findings on how the brain transmits information could lead to new ways of understanding and treating attention-related disorders, such as attention deficit hyperactivity disorder (ADHD) and schizophrenia. Saalmann worked with senior researcher Sabine Kastner, a professor in the Department of Psychology and the Princeton Neuroscience Institute; and PNI researchers Xin Li, a research assistant; Mark Pinsk, a professional specialist; and Liang Wang, a postdoctoral research associate.

The researchers developed a new technique to trace direct communication between clusters of neurons in the visual cortex and the pulvinar. The team produced neural connection maps using magnetic resonance imaging (MRI), then placed electrodes along those identified communication paths to monitor brain signals of macaques. The researchers trained the monkeys to play a video game during which they used visual cues to find a specific shape surrounded by distracting information. As the macaques focused, Saalmann and his colleagues could see that the pulvinar controlled which parts of the visual cortex sent and received signals.

Saalmann explains the Princeton findings as follows:

"A fundamental problem for the brain is that there is too much information in our natural environment for it to be processed in detail at the same time. The brain instead selectively focuses on, or attends to, the people and objects most relevant to our behavior at the time and filters out the rest. For instance, as we cross a busy city street, our brain blocks out the bustle of the crowd behind us to concentrate more on an oncoming bus.

"The transmission of behaviorally relevant information between various parts of the brain is tightly synchronized. As one brain area sends a signal about our environment, such as that a bus is approaching, another brain area is ready to receive it and respond, such as by having us cross the street faster. A persistent question in neuroscience, though, is how exactly do different brain areas synchronize so that important information isn't lost in the other stimuli flooding our brains.

"Our study suggests that a mysterious area in the center of the brain called the pulvinar acts as a switchboard operator between areas on the brain's surface known as the visual cortex, which processes visual information. When we pay attention to important visual information, the pulvinar makes sure that information passing between clusters of neurons is consistent and relevant to our behavior.

"These results could advance the understanding of the neural mechanisms of selective attention and how the brain transmits information. This is a necessary step in developing effective treatment strategies for medical disorders characterized by a failure of attention mechanisms. These conditions include ADHD, schizophrenia and spatial neglect, which is an inability to detect stimuli often observed following stroke.

"For our study, we trained monkeys to play a video game in which they paid attention to visual cues in order to detect different target shapes. We simultaneously recorded brain activity in the pulvinar and two different areas of the visual cortex. We could see a clear connective path from one portion of the cortex to another, as well as connective paths from the pulvinar to the cortex. When the monkeys paid attention to the visual cues, the pulvinar sent electrical pulses to synchronize particular groups of brain cells in the visual cortex to allow them to communicate effectively.

"A challenge in this study was that we needed to record the activity of cells that were 'speaking' directly with each other so we could trace the line of communication. But there are billions of brain cells. Traditionally, finding a cell-to-cell connection is as likely as randomly selecting two people talking on cell phones in different parts of New York City and discovering that they were speaking to each other.

"To 'listen in' on a direct cell conversation, we developed a new approach of using electrodes to record groups of brain cells that were anatomically connected. We first mapped neural connections in the brain via diffusion tensor imaging, which uses an MRI scanner to measure the movement of water along neural connections. We then used these images to implant electrodes at the endpoints of the neural connections shared by the pulvinar and the visual cortex.

"Our mapping of these communication networks and our finding that the pulvinar is vital to attention prompts a new consideration of the mechanisms behind higher cognitive function. We challenge the common notion that these functions depend exclusively on the cerebral cortex, the outermost layer of the brain responsible for decision-making, attention and language, among other abilities. It also suggests that the prevailing view that visual information is transmitted solely through a network of areas in the visual cortex needs to be revised to include the pulvinar as an important regulator of neural transmission."
