New mathematical model links space-time theories

May 30, 2013 ? Researchers at the University of Southampton have taken a significant step in a project to unravel the secrets of the structure of our Universe.

Professor Kostas Skenderis, Chair in Mathematical Physics at the University, comments: "One of the main recent advances in theoretical physics is the holographic principle. According to this idea, our Universe may be thought of as a hologram and we would like to understand how to formulate the laws of physics for such a holographic Universe."

A new paper released by Professor Skenderis and Dr Marco Caldarelli from the University of Southampton, Dr Joan Camps from the University of Cambridge and Dr Blaise Gout?raux from the Nordic Institute for Theoretical Physics, Sweden published in the Rapid Communication section of 'Physical Review D', makes connections between negatively curved space-time and flat space-time.

Space-time is usually understood to describe space existing in three dimensions, with time playing the role of a fourth dimension and all four coming together to form a continuum, or a state in which the four elements can't be distinguished from each other.

Flat space-time and negative space-time describe an environment in which the Universe is non-compact, with space extending infinitely, forever in time, in any direction. The gravitational forces, such as the ones produced by a star, are best described by flat-space time. Negatively curved space-time describes a Universe filled with negative vacuum energy. The mathematics of holography is best understood for negatively curved space-times.

Professor Skenderis has developed a mathematic model which finds striking similarities between flat space-time and negatively curved space-time, with the latter however formulated in a negative number of dimensions, beyond our realm of physical perception.

He comments: "According to holography, at a fundamental level the universe has one less dimension than we perceive in everyday life and is governed by laws similar to electromagnetism. The idea is similar to that of ordinary holograms where a three-dimensional image is encoded in a two-dimensional surface, such as in the hologram on a credit card, but now it is the entire Universe that is encoded in such a fashion.

"Our research is ongoing, and we hope to find more connections between flat space-time, negatively curved space-time and holography. Traditional theories about how the Universe operates go some way individually to describing its very nature, but each fall short in different areas. It is our ultimate goal to find a new combined understanding of the Universe, which works across the board."

The paper AdS/Ricci-flat correspondence and the Gregory-Laflamme instability specifically explains what is known as the Gregory Laflamme instability, where certain types of black hole break up into smaller black holes when disturbed -- rather like a thin stream of water breaking into little droplets when you touch it with your finger. This black hole phenomenon has previously been shown to exist through computer simulations and this work provides a deeper theoretical explanation.

In October 2012, Professor Skenderis was named among 20 other prominent scientists around the world to receive an award from the New Frontiers in Astronomy and Cosmology international grant competition. He received $175,000 to explore the question, 'Was there a beginning of time and space?''.

Adobe Kuler color selection iPhone app is now available, redesigned web interface in tow (video)

Adobe releases Kuler iPhone app for snapshot color picking, redesigns huecentric web interface

Although the shiny new iOS app and retooled web interface were demoed a few weeks back at MAX 2013, Adobe has released both facets of its new and improved Kuler color selection tool into the wild. The iPhone software enables hue selection with the handset's camera or selecting a previously captured image for inspiration -- with built-in preset moods and color rules to expedite the process when needed. Created themes can then be saved and accessed via both the web interface and inside Creative Cloud applications like Photoshop and Illustrator. The free app is available now in iTunes and a quick walkthrough resides beyond the break.

Tim Cook talks about 'the future of iOS  OS X' Ive, Cue have been working on

During an interview tonight at the D11 conference, Apple CEO Tim Cook made a few references to what we can expect at his company's WWDC 2013 event in a few weeks. As expected, he mentioned we'll see the future of iOS and OS X revealed there, and directly referenced the recent management shakeup. Craig Federighi is running both teams, and Cook mentioned designer Jony Ive has been "really key" to this version of iOS. He left it up to interviewer Kara Swisher to decide if the changes made are as dramatic as have been reported, stating only that collaboration has been enhanced, with an "amped up" intersection of hardware, software and services.

Another name dropped is that of Eddy Cue, who is busy heading up work on services since Scott Forstall's departure. We'll have to wait until WWDC to find out the fruits of the various executives' labor but Cook did leave us with this to chew on: "The whole concept was to tighten the groups even more, so we could spend more time finding magic in intersections. Seven months later, give or take, I think it has been an incredibly great change."

Rome girl to appear on ?Toddlers and Tiaras?

Brooklyn Bird is only 3 years old but she already has fame in her future.

This summer, the young Rome girl will be featured on TLC?s ?Toddlers and Tiaras,? a reality TV show that looks at the competitive world of child pageants.

Brooklyn?s mother, Ashley, said she applied for the show after learning that a pageant system Brooklyn frequently competed with, Angel Face Pageants out of Oswego, was going to be filmed for the show.

?So, for the heck of it, we applied to be featured by sending a self-made iPhone home video of her and I,? Ashley Bird said.

This was Brooklyn?s first ?glitz pageant,? which Bird said could have appealed to the show?s producers. Bird, 21 at the time of filming, was also the youngest mom in the show?s history, she said.

Camera crews filmed Brooklyn and her mom before the pageant at their Rome apartment as well as during the Angel Face Puttin? on the Pageant held April 6 in White Plains.

Bird said her daughter enjoyed ?being famous for a day,? but having her grandparents and 10-month-old brother, Brennan, there to cheer her on was her favorite part, ?since I usually take her to pageants alone.?

And did she ever make them proud, winning the Baby Face Grand Supreme award to place the highest out of all three children filmed for the episode, which will air toward the end of July or in early August.

As for what the producers will decide to show? Bird is looking forward to finding out.

?They?ll probably show the most dramatic stuff, I imagine,? she said.

Curiosity sated: Peter Molyneux reveals winner of gaming experiment

Curiosity

Curiosity: well, it hasn't killed the cat, but has it impressed the internet?

Curiosity is over. The bizarre multiplayer gaming experiment, which required players to tap away at billions of tiles on a vast online cube, finished on Sunday evening, six months after its much-hyped launch. And as promised by veteran game designer Peter Molyneux ? the brains behind this Willy Wonka-esque, endeavour ? the person who tapped the final tile was sent a video informing them of their 'life-changing' prize. They will become a god in Godus, the next game from Molyneux's company 22Cans, as well as taking a cut of the revenue.

For several minutes before the announcement, however, the gaming community was kept in considerable suspense, madly refreshing the Twitter hashtag, #whatsinsidethecube. Staff as 22Cans had to verify that the winner wasn't a bot, and that he or she was prepared to reveal what they had won. It was always an option for the final clicker to keep their prize a secret. However at 5pm, Molyneux tweeted, "He has said he will share!!!!!!!!!" and the victor was revealed as one Bryan Henderson From Edinburgh.

In the video sent to Henderson and later shared online, Molyeneux is seen in a cube-like interior, explaining the genesis of the Curiosity project before revealing the prize: "We are making a game named Godus, the whole game is about being a god to your followers, but YOU, the person who reached the centre, will be the god of all people who are playing Godus. You will decide on the rules that the game is played by. And you will share in the success of the product. Every time people spend money on Godus, you will get a small piece of that pie."

It is not yet clear how Henderson will take up his role, or what the ramifications will be for the design and development of the title. Godus is a strategy sim in the style of previous Molyneux games Dungeon Keeper, Populous and Black & White, with the player becoming a powerful deity, guiding a population of followers. The title was successfully crowd-funded on Kickstarter last year.

Reactions on Twitter ranged from grudging satisfaction to wry disappointment; and many claimed to have predicted the outcome. Journalist Matt Lees tweeted, "I actually called it. Winner of Curiosity gets to be the God in Godus. Actually called it, months ago!" Better still, game developer Dan Marshall linked to one of his own tweets, written on December 14: "Calling it now: middle of #Curiosity cube wins a leading role in #Godus."

Some reactions, though, were rather more downbeat. Games critic and academic Ian Bogost simply tweeted, "Turns out the thing inside the cube was Peter Molyneux's ego."

Mobiles same security risk as computers | Stuff.co.nz

Cyber safety organisation Netsafe is urging consumers to pay more attention to the security of their mobile devices as "cyber security awareness week" kicks off today.

Executive director Martin Cocker said mobile malware was an emerging concern.

It would be best if consumers could help nip it in the bud, before exploits became as lucrative for fraudsters as computer malware had proved.

"We need to learn from the security mistakes we have made on other platforms," he said.

Cocker said possible mobile scams included fake banking apps and fraudulent "QR" codes that, when scanned with a phone's camera, directed people's mobile browsers to a malicious website.

Netsafe had not yet seen examples of those in New Zealand, but Cocker believed that might only be a matter of time.

A fake "Angry Birds" app had circulated that let hackers send premium-priced SMS messages from victims' phones when downloaded, he said.

Surveys in the past six months suggest as many as half of New Zealanders now own mobile phones that can connect to the internet. United States security software vendor Norton said its research suggested 41 per cent of New Zealanders had had a mobile device lost or stolen but only 9 per cent reported wiping or locking their phone after it went missing.

Most smartphone and tablet owners didn't know security software was available.

(AP) ? A pair of rockets slammed into a car dealership and a residential building in strongholds of Lebanon's Hezbollah militant group in Beirut on Sunday, wounding four people in a new sign that Syria's civil war is increasingly rattling its fragile neighbor.

Lebanon's sectarian divide mirrors that of Syria, and Lebanese armed factions have increasingly taken sides in the fighting next door. There was no claim of responsibility for Sunday's rocket attacks, but they struck just hours after Hezbollah chief Hassan Nasrallah vowed to propel Syrian President Bashar Assad to victory.

In Baghdad, Syria's foreign minister offered the first direct confirmation that the Assad regime is willing to take part in talks aimed at ending the Syrian conflict. A U.N.-sponsored conference, envisioned for next month in Geneva, is to bring together representatives of the Assad regime and the Syrian opposition for talks on a political transition.

Syrian Foreign Minister Walid al-Moallem said Sunday the government is willing "in principle" to participate in the conference. He added that such talks present a "good opportunity for a political solution for the crisis in Syria," but did not say under what terms Assad would dispatch representatives.

The date, agenda and list of participants for the conference remain unclear, and wide gaps remain about its objectives.

Syrian opposition leaders have said they are willing to attend the Geneva talks, but that Assad's departure from power must top the agenda. Assad said this month that his future won't be determined by international talks and that he will only step down after elections are held.

The foreign minister's statement puts more pressure on Syria's fractured political opposition to signal acceptance as well. The main bloc, the Syrian National Coalition, was meeting in Istanbul for the fourth day Sunday to come up with a unified position on the proposed peace talks, elect new leaders and expand membership.

Louay Safi, a senior member of the coalition, said participants were bogged down in talks about the expansion, and won't be able to issue a formal statement on the Geneva talks until membership issues are settled.

The opposition's Western and Arab allies remain skeptical about the Syrian regime's commitment to negotiations. They have warned Assad that they will step up aid to Syrian rebels if the regime does not negotiate in good faith ? though U.S. reluctance to arm the rebels may have taken the bite out of such threats.

Meanwhile, fighting has continued unabated inside Syria.

For the past week, regime troops and its Hezbollah allies have waged an offensive against the strategic rebel-held town of Qusair in western Syria. They have gained ground amid heavy shelling, but rebels have held some positions.

The Qusair battle has laid bare Hezbollah's growing role in the Syrian conflict. The Shiite militant group, which has been fighting alongside Assad's troops, initially tried to play down its involvement, but could no longer do so after dozens of its fighters were killed in Qusair and buried in large funerals in Lebanon.

On Saturday, Hezbollah's leader firmly linked his militia's fate to the survival of the Syrian regime, raising the stakes not just in Syria, but also in Hezbollah's relations with rival groups in Lebanon.

"We will continue this road until the end, we will take the responsibility and we will make all the sacrifices," he said in a televised speech. "We will be victorious."

Hours after the speech, two rockets struck neighborhoods in south Beirut, a rare occurrence even in a country used to sectarian strife. Street fighting between rival Lebanese groups has been relatively common since the end of the country's 15-year civil war in 1990, but rocket or artillery attacks on Beirut neighborhoods are unusual.

One rocket struck a car dealership in the Mar Mikhael district on the southern edge of the capital, wounding four Syrian workers, according to Lebanese security officials.

After the attack, part of the rocket's main body was left embedded in the ground, where a Lebanese soldier measured its diameter. Two cars were badly damaged and others had windows shattered by shrapnel.

Another rocket hit the second floor of an apartment building in the Chiyah district, about two kilometers (one mile) away. It damaged a living room, but no one was hurt.

Lebanese media said security forces were searching for a third unexploded rocket.

A security official said rocket launchers were found in the woods in a predominantly Christian and Druse area in suburbs southeast of Beirut. The official spoke on condition of anonymity in line with regulations.

Earlier this week, a rebel commander threatened to strike Beirut's southern suburbs in retaliation for Hezbollah's involvement in Syria. The threat was made in a video showing Col. Abdul-Jabbar al-Aqidi, commander of the Syrian rebels' Military Council in Aleppo, while apparently en route to Qusair.

"We used to say before, 'We are coming Bashar.' Now we say, 'We are coming Bashar and we are coming Hassan Nasrallah,'" the commander says in the video.

"We will strike at your strongholds in Dahiyeh," he says, using the Lebanese name for Hezbollah's power center in south Beirut. The video was still posted online on Youtube on Sunday.

Hezbollah lawmaker Ali Ammar said the rocket attack took aim at coexistence among Lebanon's numerous sects and claimed the U.S. and Israel want to return Lebanon to the years of civil war. "They want to throw Lebanon backward into the traps of civil wars that we left behind," he told reporters. "We will not go backward."

Interior Minister Marwan Charbel blamed "saboteurs" and said: "We hope what is happening in Syria does not move to Lebanon."

Lebanese Sunnis sympathetic to the Syrian opposition have also been fighting in Syria alongside the rebels. Nasrallah urged both sides to fight for their side in Syria "and leave Lebanon out of it."

The fighting next door has repeatedly spilled over the border. For the past week, Assad's opponents and supporters have been clashing in the Lebanese port city of Tripoli, using mortars, grenades and machine guns to attack densely populated areas.

Noninvasive detection, diagnosis of oral cancer

May 23, 2013 ? More effective detection and diagnosis of oral cancer could result from an advance in noninvasive imaging of epithelial tissue by a Texas A&M University researcher. The research is thought to have the potential to change the way doctors initially look for precancerous and cancerous areas in a patient's mouth.

The imaging technique, which is detailed in the Journal of Biomedical Optics, is being developed by Kristen Maitland, assistant professor in the university's Department of Biomedical Engineering. It combines two separate technologies -- confocal microscopy and fluorescence lifetime imaging -- to noninvasively evaluate both the structural changes of tissue as well as molecular changes that take place on a cellular and tissue level. These morphological and biochemical changes are key factors in determining if tissue is precancerous or cancerous, Maitland says.

Typically, such evaluations are made from lab analysis of biopsies, small amounts of surgically removed tissue. The challenge for doctors, Maitland says, is determining from what areas to take a biopsy. These determinations, she says, are largely based on visual evidence. In other words, doctors rely on the naked eye to look for problematic areas that warrant a biopsy. For doctors and patients both, it's a bit of an educated guessing game. A biopsy from one area could be negative for cancer, but the tissue around it could be cancerous and remain undiagnosed.

That's even more of a concern when it comes to oral cancer examinations, Maitland says. Visually determining the areas that warrant a biopsy can be difficult, she explains, because a patient's mouth can manifest large, heterogeneous lesions that may be both benign and precancerous, which are indistinguishable by eye. Her system is designed to more precisely guide doctors to the troubled areas of a patient's mouth through the use of optical images.

"We want to enhance a doctor's ability to detect the worst state of disease in the mouth," Maitland says. "This is about increasing the diagnostic yield. For example, rather than taking a few biopsies from random sites to represent a large heterogeneous lesion, our system can guide the clinician to biopsy the tissue with the worst state of disease to provide a more accurate diagnosis, as opposed to possibly missing the cancer or precancer."

Working with Associate Professor Javier Jo, Maitland has paired two different types of imaging technologies into a single imaging system that makes use of macroscopic and microscopic approaches to produce a detailed analysis of tissue.

One technology, known as fluorescence lifetime imaging (FLIM), enables Maitland and Jo to image large areas of oral tissue with ultraviolet light in a manner that shows signs of the molecular changes associated with precancer and cancer, revealing potential trouble areas. Its overall effectiveness, however, is limited because FLIM can be "fooled" by inflamed tissue, which has a similar fluorescent signature to precancer, Maitland notes. To overcome this limitation, Maitland paired the technology with another technology known as confocal microscopy.

In contrast to FLIM, which focuses on greater areas of tissue, confocal microscopy is a single-point measurement (about 0.5 mm in this case) with a high sensitivity, Maitland says. It provides information about the morphological features of tissue -- the same types of features a pathologist would examine in a histology section, such as the nuclear size of the cells and how densely packed the cells appear -- important indicators of precancer, she notes. But just like FLIM, confocal microscopy has its own limitations, namely an incredibly small field of view (it's not much bigger than the tip of a pencil). This limited field of view makes it difficult, if not impossible, to image an entire oral cavity with this technology -- that's where FLIM technology comes in, acting as a guide for the confocal microscopy utilized in this approach, Maitland explains.

"We think the combination of these two systems will address the limitations of other optical systems," she says. "Think of the fluorescence imaging as being used for screening and the confocal microscopy being used for diagnosis. A doctor or dentist would first find the abnormal area with the fluorescence and then go in with the confocal to make the diagnosis because it's a more specific technique."

So far, the results have been promising. Maitland has been able to combine the two systems so that the macroscopic and microscopic images produced from each technology can be co-registered, meaning she can correlate those images to the same point on the tissue. Equally as important, each imaging technique is contributing valuable information, she notes.

"We've been able to get macroscopic images with the FLIM that show clear differences in signal and spatial features due to biochemical changes in the tissue that correlate with precancer, or the development of cancer," Maitland says. "With the confocal microscope, we're able to see changes in the nuclear size, and we have the necessary resolution and the depth of imaging that is required to characterize epithelial changes."

Maitland cautions that there is still work to be done before this system proceeds to large-scale clinical trials. Her team is working to obtain more data points before claiming the sensitivity and specificity required from a system such as this. She's in the process of analyzing additional data from a hamster model of oral cancer and working with the Baylor College of Dentistry to evaluate her imaging system on samples of human oral biopsy tissue.

"The hope is we develop a system that is in real time, so it provides accurate diagnostic feedback almost instantaneously, whereas the processing needed for traditional histopathology can commonly take up to a week or two," Maitland says. "A system like ours could empower doctors with the ability to determine treatment right away rather than having a patient come back weeks later to be treated. It also would enable doctors to noninvasively monitor treatment in order to determine its effectiveness on the diseased tissue."

Hofstra student killed by police during break-in

MINEOLA, N.Y. (AP) ? In what police are describing as a crime of opportunity, a wanted man with a criminal history dating nearly 15 years entered a front door that had been left open at a New York home near Hofstra University.

A short time later, the intruder, Dalton Smith, and a 21-year-old college junior, Andrea Rebello, were both dead. The two were killed early Friday by a Nassau County police officer who fired eight shots at the masked man, hitting him seven times but also accidentally hitting Rebello once in the head, Nassau County homicide squad Lt. John Azzata said Saturday.

Smith was holding Rebello in a headlock and pointing a gun at her head before he turned his gun at the officer, Azzata said, prompting the shooting.

"He kept saying, 'I'm going to kill her,' and then he pointed the gun at the police officer," Azzata said.

A loaded 9 mm handgun with a serial number scratched off was found at the scene, police said.

Nassau County Police Commissioner Thomas Dale said he had traveled to Rebello's Tarrytown, N.Y., home to explain to Rebello's parents what happened.

"I felt obligated as a police commissioner and as a parent to inform them as soon as all the forensic results were completed," Dale said.

The veteran police officer, who was not identified, has about 12 years of experience on the Nassau County police force and previously spent several years as a New York City police officer, Dale said.

The officer is currently out on sick leave. He will be the focus of an internal police investigation once the criminal investigation is completed, which is standard police procedure in any officer-involved shooting, the commissioner said.

The shooting came just days before the school's commencement ceremonies, which are scheduled for Sunday.

A university spokeswoman said students will be handed white ribbons to wear in memory of Rebello. The shooting, which took place just steps from campus, has cast a pall over the university community as it geared up for commencement.

Earlier Saturday, police announced that Smith, 30, had been wanted on a parole violation related to a first-degree robbery conviction. A warrant was issued for Smith on April 25 for absconding from parole, police said.

Smith had what police described as "an extensive criminal history," which included arrests for robbery in the first degree in 1999, promoting prison contraband in the second degree in 2000, robbery in the first degree in 2003, assault in the second degree in 2003 and robbery in the second degree in 2003.

Rebello was in the two-story home in Uniondale, N.Y., with her twin sister Jessica, a third woman and a man when Smith, wearing a ski mask, walked into the house through an open front door, Azzata said.

The door was left open after someone had moved a car that was blocking a driveway, Azzata said.

When Smith entered, he demanded valuables and was told they were upstairs, Azzata said.

Smith, apparently unsatisfied with the valuables upstairs, asked if any of the four had a bank account and could withdraw money, Azzata said. The intruder then allowed the unidentified woman to leave and collect money from an ATM, telling her she had only eight minutes to come back with cash before he killed one of her friends, Azzata said.

The woman left for the bank and called 911, according to Azzata.

Minutes later, two police officers arrived at the home and found Rebello's twin sister Jessica running out of the front door and the male guest hiding behind a couch on the first floor, Azzata said.

One of the officers entered the home and encountered Smith holding onto Rebello in a headlock, coming down the stairs, Azzata said. Smith pulled Rebello closer and started moving backward toward a rear door of the house, pointing the gun at her head before eventually threatening the officer, Azzata said.

The Rev. Osvaldo Franklin, who gave Rebello and her twin their first communions, on Saturday night told The Associated Press their mother, Nella, couldn't even speak to him earlier in the day.

"She was so devastated," said Franklin. "She's just crying. We have to pray for Andrea, to pray for Jessica because she needs help."

Franklin said a funeral is scheduled for Wednesday at Teresa of Avila Church in Sleepy Hollow, N.Y., and will be in Portuguese.

"The family's a very good family, they have very good values," he said. "They are a very good, very devoted family."

The US Military's Disastrous Plan to Use Napalm-Strapped Bats in WWII

In 1942, after having finally entered WWII, the United States Marine Corps spent two million dollars on an insane new initiative. The mission? Strap napalm bombs to bats, and send them flying on deadly kamikaze runs. Seriously.

Vacation Inspiration

While most Americans spent the days following December 7, 1941?the day of Japan's infamous attack on Pearl Harbor?confused, angry, and afraid, dentist Lytle S. James decided to be inspired.

At the time of the attack, James was on a trip to famed bat-haven Carlsbad Caverns. Eager to do his part for his country, he took note of the ferocious fliers who ruled the the caves and suggested what seemed at the time to be a perfectly sensible retaliation plan: making unsuspecting patriots out of bomb-toting bats.

If it had been anyone else's idea, this bizarre, PETA-angering, military absurdity would have died on the vine. But Lytle P. James had something other crackpots of his era could only dream of. He had the ear of First Lady Eleanor Roosevelt.

This Man Is Not a Nut

The concept itself is outlandish enough in its own right, but the truly bizarre part is that the National Research Defense Committee decided to take the idea and run with it. Renowned psychologist Donald Griffin, who had worked extensively on bats' system of echolocation, even helped overlook the trial as one of its biggest supporters, claiming in 1942:

This proposal seems bizarre and visionary at first glance, but extensive experience with experimental biology convinces the writer that if executed competently it would have every chance of success.

This was, apparently, enough to get President Franklin Delano Roosevelt on board, as a Presidential memorandum eventually went out stating:

This man is not a nut. It sounds like a perfectly wild idea but is worth looking into.

Ultimately known as Project X-Ray, the plan used Mexican free-tailed bats, which were kept calm during travel by jamming them into ice cube trays to be cooled down and forced into hibernation.

When it came time to release the (what would be thousands of) bats, a cardboard trap was supposed to spring open and send the napalm-loaded creatures deep into enemy lines. Ideally, the bats would roost in hard-to-reach places, set them on fire, and avenge the nation in the process. Unfortunately, things didn't go quite according to plan.

Trial and Horrible Error

During a test run of just six of the flying bombers, the bats unexpectedly took off a little too early and headed not for their target, but straight for the barracks. The good news: the bombs were highly effective. The bad news: again, the bombs were highly effective. The barracks quickly burst into flames?along with the general's car.

As Robert M. Neer notes in his new book, Napalm: An American Biography, "Flames? jumped from building to building. Many structures lay in ashes." It could barely have been more catastrophic.

Apparently, in an effort to maintain the secrecy of their secret weapon, research team leader Louis Fieser and his team of scientists had chosen to forego fire equipment. Not the best idea where kamikaze bomb bats are concerned. Or as Fieser casually put it, "We made a little mistake out there."

So fortunately for animal lovers and opponents of uncontrollable bomb-toting animals everywhere, this particular military mistake ended nearly as soon as it began. But not before going down as one of the most absurd military experiments in our nation's history. [Wikipedia, Smithsonian]

LOS ANGELES (CBSLA.com) ? Breast cancer survivor Sara Aguilera is this year?s honorary bat girl for the Los Angeles Dodgers.

KNX 1070?s Claudia Peschiutta reports that the mother of two was honored Sunday at Dodger Stadium.

The contest recognizes baseball fans who have been affected by breast cancer and have shown a commitment to eradicating the disease.

One person is chosen for each Major League Baseball club.

  • Breast cancer survivor Sara Aguilera is Dodgers honorary bat girl
  • Claudia Peschiutta

Aguilera was diagnosed with breast cancer a little more than a year ago and underwent a double mastectomy. She is now cancer-free.

In addition to reconstructive surgery, Aguilera says she will need to take an estrogen blocker for the next 10 years or so.

?I?m really lucky. I didn?t need any chemo or radiation so I?m very very lucky for that and I just really want to give back,? she said.

The 36-year-old Coto de Caza resident recently started an organization called, ?Feel Yourself Up.?

?Our mission is early detection through self-examination,? Aguilera said.

HP LaserJet Enterprise 700 Printer M712dn


Relatively few business printers can print at up to tabloid size (11-by-17), and the HP LaserJet Enterprise 700 Printer M712dn is a welcome addition to that club, bringing very good paper handling, low running costs, and good speed. Although its output quality could be better, the M712dn is a good choice for high-volume black-and-white printing, including at tabloid size.

Unlike most of the tabloid printers we've tested in the past few years, the M712dn is a monochrome printer. It measures 15.4 by 22.4 by 23.4 inches (HWD) and weighs 85 pounds, too big to share a desk with, and you'll want at least two people to help move it into place. The M712dn has a 600-sheet standard paper capacity, between two 250-sheet input trays and 100-sheet multipurpose feeder. (One of the two 250-sheet trays, plus the feeder, can handle tabloid-sized paper.) An abundance of feeders, extra trays, and floor-standing cabinets are available as accessories. This printer has an automatic duplexer for printing on both sides of a sheet of paper. It has a maximum monthly duty cycle of 100,000 pages, making it suitable for reasonably heavy-duty printing.

The M712dn is ePrint enabled; HP assigns an e-mail address to the printer (which you can later customize), you can send documents to that address, and the printer will automatically print them out (as long as it's connected to the Internet).

The M712dn is the middle model of three related printers. The M712n ($1,899 direct) is the simplex version, lacking the M712dn's auto-duplexer (and its Energy Star cred). The M712xh ($2,899 direct) adds a secure hard disk and a 500-sheet paper tray in addition to all the M712dn's features.

The M712dn offers USB and Ethernet (including Gigabit Ethernet) connectivity. I tested it over the Ethernet connection with a PC running Windows Vista. As for drivers, this printer has PCL plus HP's PostScript emulation, though only the PCL driver installs by default.

HP LaserJet Enterprise 700 Printer M712dn

Print Speed
I timed the M712dn on the latest version of our business applications suite (using QualityLogic's hardware and software for timing), at 9.9 effective pages per minute (ppm), decent for its rated speed of 40 pages per minute?which should be about the speed you would get if you were to print text only. (Our test suite combines text pages, graphics pages, and pages with mixed content.) It's a respectable speed, though many mono lasers are faster?the Editors' Choice Dell B5460dn , for example, zipped through our tests at 18.7 ppm.

However, none of the mono lasers we've tested in recent years other than the M712dn can print at tabloid size. I recently timed the Editors' Choice Xerox Phaser 7100/N, a tabloid color printer rated at 30 pages per minute, at 7.9 ppm on the same tests?though it output most of the pages in color. I clocked another tabloid-sized color printer, the Dell 7130cdn at 8.3 ppm.

Output Quality
Overall output quality for the M712dn was slightly below par for a mono laser, with sub-par text, average graphics, and typical photo quality. With text there was a tendency for some letter pairs to be run together at larger sizes than usual, but even sub-par laser text is fine for typical business use. Just make a point of avoiding smaller type sizes.

In a couple of illustrations, the printer had trouble rendering distinctions between slightly different shades. Though the printer is otherwise fine for printing basic PowerPoint presentations or charts in a report, at least for in-house use, you'd have to be careful that different sections in a pie or bar chart, for instance, are distinguishable from each other.

Photo quality is suitable for printing out recognizable images from Web pages, and perhaps for photos in client newsletters, depending on how picky you and the client are. A couple of prints showed mild banding (a pattern of faint striations), most showed dithering (graininess), and there was some loss of detail in both bright and dark areas.

Running costs for the M712 are a low 1.3 cents per page, beating out the Dell 7130cdn's cost per monochrome page of 1.7 cents and the Xerox 7100/N's 2.2 cents.

As a monochrome laser, the M712dn offers good paper handling, including the ability to print at tabloid size, low running costs, and decent speed. Its output quality is good enough for typical in-house business use. The Editors' Choice Xerox Phaser 7100/N has a smaller paper capacity, higher running costs, and lacks an auto-duplexer, though one is available on the Xerox 7100/DN ($1,800). It sells at a lower price, though, its output quality is better than the M712dn's, and it can print not just monochrome but color at tabloid size.

If your business isn't too picky about output quality, doesn't require color, and you need to print in high volume, the HP LaserJet Enterprise 700 Printer M712dn could well be your preferred tabloid-sized workhorse printer. It has a relatively high monthly duty cycle, very low running costs (allowing you to recoup your relatively large investment over time), and good paper capacity; you can keep one tray loaded with tabloid-sized paper, the other with letter or legal, and the multipurpose tray free for other paper types or sizes.
