Erectile dysfunction signals heart troubles: study

WASHINGTON: Erectile dysfunction might signal more than a need for the little purple pill, researchers said Tuesday in a study showing a link with heart disease and early death.

The Australian study -- the world's largest investigating links between erection problems and heart disease -- suggested erection problems could act as a warning sign of more serious health issues.

"The risks of future heart disease and premature death increased steadily with severity of erectile dysfunction," whether or not there was a history of cardiovascular disease, study director Emily Banks said.

Previous studies had found ties between severe erection problems and heart attacks and strokes, but this study was the first to also include mild and moderately severe erection problems.

"These results tell us that every man who is suffering from any degree of erectile dysfunction should be seeking medical assistance as early as possible and also insisting on a heart health check by their GP at the same time," said Rob Grenfell, Cardiovascular Health director at Australia's Heart Foundation.

The study, published this week in the "PLOS Medicine" journal, followed 95,000 men aged 45 and older for two to three years.

The men responded to a survey on their health and lifestyle, and the authors also studied any records of hospital stays or deaths in the group.

Over the study period, there were 7,855 hospitalisations for cardiovascular disease and 2,304 deaths.

Banks said that the study indicated that erection problems seemed to a symptom of heart problems.

"Rather than causing heart disease, erectile dysfunction is more likely to be a symptom or signal of underlying 'silent' heart disease and could in future become a useful marker to help doctors predict the risk of a cardiovascular problem.

"This is a sensitive topic but men shouldn't suffer in silence; there are many effective treatments, both for erectile dysfunction and for cardiovascular disease," she emphasized.

Erection problems are very common. About one in five men over 40 report moderate or severe erectile dysfunction.

Army rejects bid to raise new units based on caste or religion

NEW DELHI: The Army has once again strongly rejected calls for raising new "single-class" units like the Gujarat, Kalinga, Dalit, Ahir, Paswan or Tribal regiments as well as attempts to tinker with its "time-tested" regimental system.

"The policy since Independence is not to raise any new regiment on the basis of a particular class, creed, community, religion or region but to have a force in which all Indians have representation. This is the well-defined position of both the defence ministry and Army," said a senior official.

Added a top general, "Politics should not be played with the apolitical armed forces. The Army is an inclusive, secular force, open to all. It's for that reason the force had even opposed the religious headcount proposed by the Sachar Committee in 2005-06."

Having just finished with the Republic Day celebrations as well as the Army Day on January 15, which marks the day when Field Marshal K M Cariappa became the first Indian chief of the force in 1949, the 1.13-million-strong Army is equally steadfast about resisting any changes in its regimental system.

But it's the existence of this system, with a preponderance of "single-class" regiments like the Sikh, Gorkha, Dogra, Garhwal, Jat and the like, which propels politicians and others to demand a Dalit Regiment, like LJP chief Ram Vilas Paswan often does, or a Gujarat Regiment, as proposed by L K Advani when he was the deputy prime minister.

Single-class or "pure" regiments were raised during the Raj based on the classification of certain communities as "martial races". After 1947, India, however, decided to continue with these caste or community-based units because "regimental history, ethos and loyalty" was considered to be the main driving force in combat effectiveness and operational performance.

"Soldiers from the same clan fight better from the same foxhole. These tradition-bound regiments have proved themselves in combat in all conflicts since 1947. They should not be dismantled," said a major-general.

This "battalion esprit de corps" was quite evident during the 1999 Kargil conflict. Quizzed why they had made those daredevil assaults against fortified positions held by Pakistani intruders, the common refrain among jawans was that the "paltan's izzat" (the battalion's honour) was at stake, more than loftier notions about fighting for the flag and the country.

While officers can be commissioned into any unit, the infantry's 23 regiments — with over 350 battalions under them — are basically of three types. Single-class units constitute around 60% of the whole. Even among them, the further sub-divisions are based on community or caste. The Army's seven Gorkha Rifles, for instance, recruit separately from the Gurung, Rai, Limbu, Magar and other communities, both from India and Nepal.

The aim after Independence has been to raise "All India-All Class" regiments, like the Brigade of Guards, where jawans are recruited from all over the country irrespective of class and percentage. "The endeavour is to progressively move towards such regiments," said a Brigadier.

In between these two are the "mixed" and "fixed" class units like the Grenadiers or the Mahar Regiment. The 4 Grenadiers, for instance, has two companies of Jats, one company of Muslims and one company of Dogras. Similarly, Rajputana Rifles has an equal mix between Rajputs and Jats, while the Rajput Regiment mainly has Rajputs and Gujars with a sprinkling of Muslims and Bengalis.

"Jawans, with similar language and eating habits, have kinship, brotherhood...they form a cohesive fighting force. Even in mixed class regiments like Grenadiers, individual companies - the basic fighting units — are `pure'," said a Colonel.

The other "fighting arms" like the armoured corps and artillery also have several instances of "pure" units among them. Many artillery medium or field regiments, for instance, are "pure" ones recruiting only Gorkhas, Sikhs, Jats, Ahirs or Marathas into their respective folds. But "support" arms like ASC, EME, Ordnance, Signals and the like are resolutely "all-class" units.

Timbuktu’s vulnerable manuscripts are city’s "gold"

French and Malian troops surrounded Timbuktu on Monday and began combing the labyrinthine city for Islamist fighters. Witnesses, however, said the Islamists, who claim an affiliation to al Qaeda and had imposed a Taliban-style rule in the northern Malian city over the last ten months, slipped into the desert a few days earlier.

But before fleeing, the militants reportedly set fire to several buildings and many rare manuscripts. There are conflicting reports as to how many manuscripts were actually destroyed. (Video: Roots of the Mali Crisis.)

On Monday, Sky News posted an interview with a man identifying himself as an employee of the Ahmed Baba Institute, a government-run repository for rare books and manuscripts, the oldest of which date back to the city's founding in the 12th century. The man said some 3,000 of the institute's 20,000 manuscripts had been destroyed or looted by the Islamists.

Video showed what appeared to be a large pile of charred manuscripts and the special boxes made to preserve them in front of one of the institute's buildings.

However, a member of the University of Cape Town Timbuktu Manuscript Project told eNews Channel Africa on Tuesday that he had spoken with the director of the Ahmed Baba Institute, Mahmoud Zouber, who said that nearly all of its manuscripts had been removed from the buildings and taken to secure locations months earlier. (Read "The Telltale Scribes of Timbuktu" in National Geographic magazine.)

A Written Legacy

The written word is deeply rooted in Timbuktu's rich history. The city emerged as a wealthy center of trade, Islam, and learning during the 13th century, attracting a number of Sufi religious scholars. They in turn took on students, forming schools affiliated with's Timbuktu's three main mosques.

The scholars imported parchment and vellum manuscripts via the caravan system that connected northern Africa with the Mediterranean and Arabia. Wealthy families had the documents copied and illuminated by local scribes, building extensive libraries containing works of religion, art, mathematics, medicine, astronomy, history, geography, and culture.

"The manuscripts are the city's real gold," said Mohammed Aghali, a tour guide from Timbuktu. "The manuscripts, our mosques, and our history—these are our treasures. Without them, what is Timbuktu?"

This isn't the first time that an occupying army has threatened Timbuktu's cultural heritage. The Moroccan army invaded the city in 1591 to take control of the gold trade. In the process of securing the city, they killed or deported most of Timbuktu's scholars, including the city's most famous teacher, Ahmed Baba al Massufi, who was held in exile in Marrakesh for many years and forced to teach in a pasha's court. He finally returned to Timbuktu in 1611, and it is for him that the Ahmed Baba Institute was named.

Hiding the Texts

In addition to the Ahmed Baba Institute, Timbuktu is home to more than 60 private libraries, some with collections containing several thousand manuscripts and others with only a precious handful. (Read about the fall of Timbuktu.)

Sidi Ahmed, a reporter based in Timbuktu who recently fled to the Malian capital Bamako, said Monday that nearly all the libraries, including the world-renowned Mamma Haidara and the Fondo Kati libraries, had secreted their collections before the Islamist forces had taken the city.

"The people here have long memories," he said. "They are used to hiding their manuscripts. They go into the desert and bury them until it is safe."

Though it appears most of the manuscripts are safe, the Islamists' occupation took a heavy toll on Timbuktu.

Women were flogged for not covering their hair or wearing bright colors. Girls were forbidden from attending school, and boys were recruited into the fighters' ranks.

Music was banned. Local imams who dared speak out against the occupiers were barred from speaking in their mosques. In a move reminiscent of the Taliban's destruction of Afghanistan's famous Bamiyan Buddha sculptures, Islamist fighters bulldozed 14 ancient mud-brick mausoleums and cemeteries that held the remains of revered Sufi saints.

A spokesman for the Islamists said it was "un-Islamic" for locals to "worship idols."

Jodi Arias Borrowed Gas Cans Before Killing Ex

Accused murderer Jodi Arias borrowed two five-gallon gas cans from a former boyfriend the day before she drove to Arizona to kill another ex, Travis Alexander, according to testimony in Arias' murder trial today.

In cross examination, prosecutors also forced Arias' former live-in boyfriend Darryl Brewer to describe his sex life with Arias as "pretty aggressive."

Brewer, 52, dated Arias for four years and shared a home with her in California for two years. He told the court today that Arias called him in May 2008, asking to borrow gas cans, but would not explain why. She called him again at least two more times, and arrived at his house on June 2008, to borrow the cans.

On the day she picked up the gas cans she told Brewer that she was going to visit friends in California and Arizona.

Prosecutors argue that Arias then drove to Mesa, Ariz., where she allegedly had sex with Alexander, took nude photos of him, and then stabbed him 27 times, slashed his throat, and shot him twice in the head. She is charged with murder and could face the death penalty if convicted.

Arias, who claims she killed Alexander in self defense, had approached prosecutors two years ago offering to plea to a second degree murder charge, which could carry a 25 year term, but the state rejected the offer, Nancy Grace reported on Good Morning America today.

Brewer said that Arias never returned the gas cans. The pair had been broken up two years earlier and they had only spoken "sporadically," he said.

Prosecutors also showed receipts from Arias' trip from her California home to Alexander's home in Mesa, showing that she purchased a 10 gallons of gas at one gas station the night before she drove to Arizona, and then another 10 gallons from a different gas station 10 minutes later. Prosecutors are expected to argue she brought the gas with her to fill up her car secretly on the way to Alexander's home, showing premeditation for the murder.

Arias' attorneys called Brewer as one of their first witnesses as they began mounting their case that Arias killed Alexander in self defense, arguing that Alexander was controlling and abusive toward Arias.

They asked Brewer to explain how he and Arias had been in a stable relationship for four years, from 2002 to 2006, and had bought a home together before Arias met Alexander at a business conference and began to change.

"I saw a lot of changes in Jodi. She became a different person than I had known previously," Brewer said, describing how Arias' behavior changed in May 2006 when she joined a company called Pre-Paid Legal. There, she met Alexander and began seeing him. She continued to live with Brewer.

"She had continued to pay the mortgage, but she was not paying other household bills, she began getting into debt or financial trouble," Brewer said. "For me it seemed she was not as rational or logical."

Arias also converted to Mormonism while living with Brewer, telling him that he could no longer curse and she would no longer have sex with him because she was saving herself for marriage.

The pair had previously had an "enthusiastic" and "aggressive" sex life, Brewer admitted to prosecutors. They had engaged in anal sex, Arias had taken nude photos of Brewer, and Arias had purchased breast implants in 2006, he testified.

Brewer said that after Arias began to change, he made arrangements to move closer to his son from his first marriage, and he and Arias broke up.

They kept in touch with occasional phone calls until Arias asked to borrow the gas cans in June 2008, and then called him a week after borrowing the cans to say that her friend had been killed.

Martinez, reading notes from an interview Brewer gave to authorities during the investigation into Alexander's death, asked if Arias had ever mentioned needing an "alibi." Brewer said he did not recall any conversation about alibis.

"After this date of June 4, 2008," Martinez asked, "you received a call from Jodi Arias, and she was very agitated?"

"She was sad," Brewer said.

"Did she tell you that her friend had been killed and she did not have an alibi?"

"I don't remember that," Brewer said.

Arias was arrested a month after Alexander was found dead, in July 2008.

Bipartisan group of senators to unveil framework for immigration overhaul

A key group of senators from both parties will unveil on Monday the framework of a broad overhaul of the nation’s immigration laws, including a pathway to citizenship for more than 11 million illegal immigrants.

The detailed, four-page statement of principles will carry the signatures of four Republicans and four Democrats, a bipartisan push that would have been unimaginable just months ago on one of the country’s most emotionally divisive issues.

The document is intended to provide guideposts that would allow legislation to be drafted by the end of March, including a potentially controversial “tough but fair” route to citizenship for those now living in the country illegally.

[Do you think the new immigration plan will work? Discuss this and other immigration issues in The Washington Post’s new political forums.]

It would allow undocumented immigrants with otherwise clean criminal records to quickly achieve probationary legal residency after paying a fine and back taxes.

But they could pursue full citizenship — giving them the right to vote and access to government benefits — only after new measures are in place to prevent a future influx of illegal immigrants.

Those would include additional border security, a new program to help employers verify the legal status of their employees and more-stringent checks to prevent immigrants from overstaying visas.

And those undocumented immigrants seeking citizenship would be required to go to the end of the waiting list to get a green card that would allow permanent residency and eventual citizenship, behind those who had already legally applied at the time of the law’s enactment.

The goal is to balance a fervent desire by advocates and many Democrats to allow illegal immigrants to emerge from society’s shadows without fear of deportation with a concern held by many Republicans that doing so would only encourage more illegal immigration.

“We will ensure that this is a successful permanent reform to our immigration system that will not need to be revisited,” the group asserts in its statement of principles.

The framework identifies two groups as deserving of special consideration for a separate and potentially speedier pathway to full citizenship: young people who were brought to the country illegally as minors and agricultural workers whose labor, often at subsistence wages, has long been critical to the nation’s food supply.

Expanding visas

The plan also addresses the need to expand available visas for high-tech workers and promises to make green cards available for those who pursue graduate education in certain fields in the United States.

“We must reduce backlogs in the family and employment visa categories so that future immigrants view our future legal immigration system as the exclusive means for entry into the United States,” the group will declare.

The new proposal marks the most substantive bipartisan step Congress has taken toward new immigration laws since a comprehensive reform bill failed on the floor of the Senate in 2007.

Golf: Tiger wins Torrey Pines title for 75th career crown

LA JOLLA: World No. 2 Tiger Woods captured his 75th career title on Monday, winning the US PGA Farmers Insurance Open by four strokes for his record-setting eighth career triumph at Torrey Pines.

Despite struggling in windy conditions Monday over the final 11 holes, Woods showed flashes of the form that has brought him 14 major titles as he chases the all-time record of 18 won by Jack Nicklaus.

Woods won his most recent major title at the 2008 US Open at Torrey Pines and has also won the PGA event staged at Torrey Pines seven times. No other PGA player has won so many times on a single course.

A fog delay Saturday led to the Monday finish, with darkness halting Woods on Sunday after seven holes.

Woods completed a final-round par 72 Monday despite going three-over in the closing stretch, finishing 72 holes on 14-under par 274. Brandt Snedeker, the 2012 winner, and Josh Teater shared second on 278.

Woods had two bogeys and a double bogey between the 14th and 17th holes, but managed a par at the par-5 18th to close out the victory.

"It got a little ugly toward the end," Woods said. "I started losing my patience with slow play and lost my concentration there a little bit. But I was able to get my par there at 18 and got the win."

After missing the cut in his season opener at Abu Dhabi, Woods collected his first victory since last July at the US PGA National at Congressional.

Mahakumbh of the mind ends on a dramatic high

JAIPUR: It featured high controversy and deep content, emotional commemoration and vibrant celebration. The 2013 chapter of the Jaipur Literature Festival (JLF), often called the Maha Kumbh of the mind, officially pulled down the curtain on Monday after five days of energetic events attended by enormous crowds.

Notable events included a tribute to the late Bengali writer Sunil Gangopadhyay, a triumphant discourse of defiance by iconic Bengali writer Mahashweta Devi, colourful debates on religions, empires and Bollywood alongside in-depth discussions on writing fiction, reporting facts and discerning change within societies. All together with the now familiar political protests that the event has almost made a habit to attract.

The choice of events within the JLF was dazzling—in one location, cultural theorists Gayatri Spivak discussed the art of criticism with others while at another investment expert Ruchir Sharma outlined methods of economic pragmatism. At another, writers from Ian Buruma to Swapan Dasgupta discussed the sun setting on the empire while Upamanyu Chatterjee and Amit Choudhari read from their books, describing a strange, sublime and eccentric post-colonial India.

Travel writers from Pico Iyer to Samanth Subramanian described the art of falling off maps, as it were, while Madeline Miller, Lawrence Norfolk and Linda Grant discussed writing historical fiction from the odd standpoint of both knowing and not knowing how your plot could proceed. All along, Buddhist chants preceded in-depth discussions on diverse facets of Buddhist literature while strands of feminist writing as well as vernacular and diasporic writing was celebrated.

In the middle of it all came the now famous session 'The Republic of Ideas' featuring academic Ashis Nandy on a panel that debated corruption, red tape and the freedom of speech as building blocks or loose bolts in a nation's architecture. Confronted with dazzling diversity, the crowds seemed to lap the sessions. The Bollywood discussions were predictably swamped by huge numbers, eager to know more about beloved classics as well as the winds of change sweeping through a much-adored cinema. Similarly, a cricket book session featuring sports icon Rahul Dravid was flooded by fans. However, the less-predictable sessions—a crackling discussion on the ethics of reading, translation and the post-colonial between Spivak and Amit Chadhuri, for instance—were similarly inundated.

The audience was as colourful as the sessions, featuring young students clued into texts, appreciative fiction lovers, fans of history and travel narratives, seekers of spiritual solace, Jaipur's beau monde, all glittering with elaborate hair-clips and gleaming jewellery, as well as a few gentle souls who simply wanted to doze in the sun. The sleepy air was shaken when protests broke out over comments of Nandy on January 26 with the protestors filing a police complaint and demanding arrests. Audience at the JLF was left wondering not only at the finest writing, the best authors and their most polished works but also about the freedom to think aloud, to provoke, to protest and to debate. In the best traditions of literature, the JLF 2013 presented answers and questions for readers and writers alike.

Space Pictures This Week: Martian Gas, Cloud Trails

Image courtesy SDO/NASA

The sun is more than meets the eye, and researchers should know. They've equipped telescopes on Earth and in space with instruments that view the sun in at least ten different wavelengths of light, some of which are represented in this collage compiled by NASA and released January 22. (See more pictures of the sun.)

By viewing the different wavelengths of light given off by the sun, researchers can monitor its surface and atmosphere, picking up on activity that can create space weather.

If directed towards Earth, that weather can disrupt satellite communications and electronics—and result in spectacular auroras. (Read an article on solar storms in National Geographic magazine.)

The surface of the sun contains material at about 10,000°F (5,700°C), which gives off yellow-green light. Atoms at 11 million°F (6.3 million°C) gives off ultraviolet light, which scientists use to observe solar flares in the sun's corona. There are even instruments that image wavelengths of light highlighting the sun's magnetic field lines.

Immigration Plan Includes Path to Citizenship

A bipartisan group of senators on Monday formally unveiled their proposal to drastically overhaul the nation's immigration system, with the hope of passing a bill out of the Senate by late spring or early summer.

"We believe this will be the year Congress finally gets it done," Sen. Chuck Schumer (D-N.Y.) one of the members of the so-called "Gang of Eight" said during a press conference on Capitol Hill.

See Also: Transcript: Framework for Immigration Reform

Five of the eight members of the group -- Schumer, Bob Menendez (D-N.J.), Dick Durbin (D-Ill.), Marco Rubio (R-Fla.), and John McCain (R-Ariz.) -- appeared at the press conference intended to outline their immigration proposal. The proposal would provide a path to citizenship for many of the nation's 11 million undocumented immigrants while upping border security and cracking down on businesses that hire workers who are not legally present in the U.S.

Sens. Jeff Flake (R-Ariz.), Lindsey Graham (R-S.C.), and Michael Bennet (D-Colo.) were the members not in attendance.

The senators all expressed optimism that their legislation could pass both the House and the Senate. Schumer added that he hopes to have an actual piece of legislation done by the end of March, and then have the Senate act on it right away.

But while some conservatives have signaled support for the Senate framework, many others have resisted any plan that could grant a pathway to citizenship to undocumented immigrants, saying it amounts to amnesty for people who broke the law.

The Senate's plan does not grant undocumented immigrants automatic "amnesty," rather it requires them to go through an arduous process that includes undergoing a background check, paying fines, back taxes and learning English and American civics over the course of a number of years. The new law would grant eligible undocumented immigrants permission to live and work in the U.S. legally, but would not confer permanent legal status, or a green card, until the border is deemed to be secure. Young people brought into the U.S. illegally as minors and some agricultural workers would face an easier path to citizenship.

"We will never put these people on a path to citizenship until we have secured the border," Schumer said.

McCain, who helped lead the last effort on a comprehensive immigration bill in 2007 said, "We have been too content for too long to allow individuals to mow our lawns, grow our food, clean our homes, and even watch our children while not affording them any of the benefits that make our country so great."

Senators in both political parties suggested that the reason that some Republicans have had a change of heart was because of the results of last November's election, when seven in 10 Latino voters backed President Barack Obama over Republican Mitt Romney.

"The politics on this issue have been turned upside down," Schumer said. "For the first time ever, there is more political risk in opposing immigration reform, than in supporting it."

Perhaps more than anyone on the stage, McCain understands this. While he backed comprehensive immigration reform five years ago, he backed away from it during his 2010 run for Senate, just as his home state was considering the SB 1070 crackdown law on undocumented immigrants.

McCain went so far as to say that the current plan is a "testimonial" to bill he worked on with Sen. Ted Kennedy (D-Mass.), the late liberal icon, in 2007.

Another member of the group, Marco Rubio, had not always voiced support for a pathway to citizenship for undocumented immigrants during his Senate career. But on Monday, he said that Congress needs to "address the reality" of the massive undocumented population in the U.S.
