Video: Cardinal Dolan has ?mixed feelings? about conclave



>> dolan is president of the conference of catholic bishops and just took part in this morning's meeting. your em m your eminence, nice to meet you.

>> good morning. last time i was skuk wituck with al roker and matt lauer . it is a blessing.

>> and you had a chance to be with the pope in his final hours of his papacy. what was that like?

>> i don't mind telling you it was somber. we catholics call him our holy father and the papa, the daddy. to see this gentle loving holy man, to see him very fragile, see him made what i consider to be a remarkably humble and courageous decision, it was very moving. it was a very tender moment. i was honored when i went up. i only had a little while with him. i was honor he remembered my name. always good when the boss knows your name. i was glad he remembered gratefully his visit to the archdiocese in new york in 2008 . i said to him, holy father, i love you, thank you, praying with you and for you and so are the people of the archdiocese in new york and i meant it.

>> even as we say good-bye to this pope, thoughts inevitably turn to his successor. you've been here 24 hours and i know you have seen a bit of your fellow cardinals who will make this difficult choice. how much urgency do you and your fellow cardinals feel to gets the conclave started and moving?

>> there's kind of a mixed feeling if i'm detecting it right, savannah. i'm a rookie and never participated in a conclave before. you hear the cardinals say there's a strong desire to have a new pope as soon as possible. for that to happen in the most prudent enlightened way we need prayer and reflection to get to know each other. you did hear the dean of the college of cardinals said we would begin the general congregations, not the conclave, the meetings prior. we will begin those on monday. one of the items on the agenda for the congregation of cardinals , when will we begin the conclave?

>> are there any front runners for his successor and feel free to name names.

>> i'm not trying to dodge your question. i'm finding myself on two levels, first, the morning of the departure of pope benedict and celebrating what i say is his great leg gassy and only now i said, these are my brother cardinals i will be in conclave before too long. only now i would concentrate on the who. there are some names that come to my mind. you wouldn't be surprised i don't feel comfortable sharing with you. i say all the cardinals praying for guidance, looking closely to other cardinals and looking forward to reflection and apostolic eenterty.

>> i heard some say on a shocker scale, this is a 10 on a scale of 1-10. we have seen in the last few days some of the scandals of the catholic church laid bare. in some ways it seemed to have laid bare open wounds. do you think in that way the resignation is not a mistake?

>> i wouldn't say that. i would have such regard for the holy father's prayer and decision making that it isn't a mistake. you've got a point. there's always been sin and scandal and corruption in members of the church. at a time like this when the church is under such intense scrutiny. those will always come through. we call the church as the mystical body of christ. there are warts and scars. and st. agust stin says often the church limps because the church is in pain and sometimes wounded. we see that now. all that means, i would hope, we use this time for spiritual renewal, rededication to the valuable goals benedict the saxvi has put out and time for spiritual rededication for the church.

>> when you walk into the sistine chapel behind us as cardinal and come out as the next pope?

>> about the same for a me taking a-rod's place on the new york yankees.

>> i'm not a baseball affection aficionado. but i get your drift.

>> hope to see you.

>> thank you.

Sperm swim against the current

Human and mouse male reproductive cells find the egg by migrating upstream

By Meghan Rosen

Web edition: March 1, 2013

Mammalian sperm just don?t go with the flow.

The little swimmers use head-on currents to guide themselves up fallopian tubes toward an egg, a new study suggests. Sex triggers fluids to spurt from the fallopian tubes, where tiny bristles called cilia sweep the fluid from the ovaries to the uterus. The moving fluid hands sperm a map to their target, researchers report online February 28 in Current Biology.

?I like this paper because it stirs up the field,? says Susan Suarez, a reproductive biologist at Cornell University in Ithaca, N.Y., who specializes in sperm movement. Scientists had proposed two other ways sperm might find eggs: by sniffing out chemicals or by sensing changes in heat.

Theories about mammalian sperm?s chemical-sensing tactics first came from marine animals. Sea urchins squirt sperm into the ocean; the swimming cells chase down a trail of egg-secreted chemicals, like mice following breadcrumbs to lunch. But mammalian fertilization is more complicated, says Kiyoshi Miki of Boston Children's Hospital.

Female mammals have long, winding fallopian tubes, so a chemical trail there might fizzle out, Miki says. And no one has pinned down convincing sperm-luring biochemicals. Miki and his colleague David Clapham decided to look into the other proposed sperm strategy: using temperature clues to home in on the egg.

When the scientists placed mouse or human sperm in a chamber with warm liquid on the bottom and cooler liquid on top, they noticed that the temperature gradient spurred tiny fluid currents. And the sperm cells in the dish consistently swam upstream. ??It was very clever of them to notice the currents,? Suarez says.

Miki and Clapham measured fluid secretion in dissected, living mouse fallopian tubes, to see what currents sperm usually contend with. After animals mated, they found, fallopian tube juices got flowing.

The scientists mimicked the fluid flow in a culture dish by hooking up a tiny glass tube to a device called a micromanipulator and using it to slowly suck sperm into the tube. Then the researchers watched which way the cells moved. Nearly all the sperm swam away from the suction source.

?When we first saw this, it was very exciting,? Miki says. ?It was a beautiful, coordinated thing.?

But the idea that sperm use currents to navigate was not exactly mainstream. Researchers had reported this against-the-flow phenomenon in mammalian sperm back in 1876. Several scientists had since revisited the peculiar finding, but dismissed it as a laboratory quirk. In the last few decades, however, scientists have built better tools for watching sperm move; Miki is convinced his results are real.

Miki and Clapham believe sperm?s rotating tails drive their tendency to turn upstream: In culture dishes, even headless sperm ? a tiny fraction of normal sperm populations ? oriented against the fluid flow. But sperm that couldn't spin their tails didn?t swim upstream.

?This mechanism of sperm guidance is important, no doubt about it,? says biochemist Michael Eisenbach of the Weizmann Institute of Science in Rehovot, Israel. ?Still, he says, it may coexist with temperature- and chemical-guided strategies.

Miki speculates that the findings could provide clues to infertility or contraception. Blocking tail rotation in human sperm or fluid flow in fallopian tubes could prevent fertilization, he says.

New model could lead to improved treatment for early stage Alzheimer's

Feb. 28, 2013 ? Researchers at the University of Florida and The Johns Hopkins University have developed a line of genetically altered mice that model the earliest stages of Alzheimer's disease. This model may help scientists identify new therapies to provide relief to patients who are beginning to experience symptoms.

The researchers report their findings in the current issue of The Journal of Neuroscience.

"The development of this model could help scientists identify new ways to enhance brain function in patients in the early stages of the disease," said David Borchelt, UF professor of neuroscience in the Evelyn F. and William L. McKnight Brain Institute and director of the SantaFe HealthCare Alzheimer's Disease Research Center. "Such therapies could preserve brain function longer and delay the appearance of more severe symptoms that leave patients unable to care for themselves."

In the early stages of Alzheimer's disease, people struggle with and fail to learn new games, rules or technologies because their cognitive flexibility decreases. The degenerative disease continues with memory loss and the decline of other brain functions.

The researchers worked with mice that had specially designed gene fragments derived from bacteria and from humans that allowed the investigators to control the production of a small peptide. The peptide, called amyloid beta peptide, is a short chain of amino acids. Accumulations of this particular peptide in the brain as lesions called plaques occur early in the progression of Alzheimer's disease and seem to trigger the early memory problems.

The team regulated the expression of the peptide using antibiotics -- when the animals stopped taking the antibiotic, the peptide-producing gene turned on and caused the mice to develop the plaques found in Alzheimer's patients. After the mice had developed the Alzheimer pathology, the researchers turned the gene back off and observed that the mice showed persistent memory problems that resemble the early stages of the disease.

"This model may be useful to researchers to test drugs that could help with symptoms of early stage Alzheimer's disease," Borchelt said.This research is funded by the National Institute of Neurological Disease and Stroke of the National Institutes of Health, and the SantaFe HealthCare Alzheimer's Disease Research Center of the University of Florida.

Bluehost Web Hosting - Best PSD to HTML

Why do I consider Bluehost to be the best web hosting company of all? There are quite a few reasons, some of which I?ll address in this article.

I first came to know about Bluehost on a web hosting review website called 100 Web Hosting which ranked Bluehost as the best web host on their top 10 web hosting list. The site also shares a lot of articles about Bluehost, such as their control panel demo, their support, their hosting features and even a Bluehost infographic.

Bluehost Web Hosting: the Basics

Bluehost is a large web hosting company that hosts millions of domains and websites all over the world. While they?re not the biggest web host in the world, they are quickly growing. They consistently manage to acquire more than 20,000 new customers each month, so they must be doing something right! I am not a professional web hosting reviewer, but if you want more details, you can check out a detailed Bluehost review on 100 Web Hosting.

You may be surprised to learn that Bluehost has been around since 1996, which makes it one of the older and more experienced web hosts around. They?ve been hosting websites since the early days of the internet.

Professional Web Hosting Plan

Most people who sign up for web hosting choose a type of shared hosting plan. This is the most reasonable type of web hosting, and it serves the purposes of most bloggers and website owners. It?s even sufficient for most small online businesses, as you can still set up shopping carts and other e-commerce features with Bluehost?s shared hosting.

Many web hosts offer several different shared hosting plans, but Bluehost only has one ? the Professional Web Hosting package. While you might like the idea of being able to choose between plans, this is really not a disadvantage when you look at what?s included with this package.

Here is some of what you get with this plan:

  • Unlimited domains, hosting space and file transfers
  • Secure shell, SSL and FTP
  • Free domain registration
  • Site builder with choice of templates
  • Email, chat and phone support 24/7
  • $100 in Google advertising credits
  • Money back guarantee

The cost for this hosting plan is competitive. The normal monthly fee for shared hosting is $6.95, but you can often find it for a dollar or two less if the company is running a sale.

Additional Features of Bluehost Web Hosting

Aside from the above, you get many other benefits with Bluehost?s web hosting. Some of these include:
1. Website Scripts ? You can easily install many useful scripts, such as WordPress, b2evolution, Drupal, Joomla, poll and survey software, mailing lists and more.
2. Multimedia ? Video and audio streaming, MIDI file support, add custom MIME types.
3. E-Commerce Features ? Start your own online store with an SSL Secure Server and a choice of shopping carts such as Zen Shopping Cart, Agora, Cube Cart and OS Commerce.

What?s great about these features is that they are all simple to use and require no advanced technical knowledge. Bluehost is, for example, well known as one of the best hosting companies for WordPress. You can install this popular blogging platform in seconds.
The same is true for other scripts, such as shopping carts. In some cases, there may be a certain learning curve to master all of the features of an application. However, Bluehost ensures that the installation process is fast and simple.

Conclusion

With so many web hosting companies to choose from, it can be difficult to decide which is best. What I like about Bluehost is that it?s large and experienced enough to provide fast and secure hosting yet still manages to maintain a customer friendly attitude.

Some large web hosts seem to put a high percentage of their budget into advertising and public relations. This is not the case with Bluehost. While you may see their ads, they don?t follow you around the internet like those of some companies.

No matter what features you?re looking for in a web host, Bluehost will most likely have it. Since they offer a money back guarantee, there?s hardly any risk in trying them out.

Odds against him, Obama still betting on big deal

(AP Photo/J. Scott Applewhite)

(AP) ? A fiscal deadline all but blown, President Barack Obama says he once again wants to seek a big fiscal deal that would raise taxes and trim billions from expensive and ever growing entitlement programs. But with automatic federal spending cuts ready to start taking their toll, the path toward that grand bargain Obama campaigned on last year has significantly narrowed.

The president has summoned the top bipartisan congressional leadership to the White House, a meeting designed to give all sides a chance to stake out their fiscal positions with a new threat of a government shutdown less than four weeks away. There were no expectations of a breakthrough.

But for Obama, Friday's session would be his first opportunity to spell out his 10-year, $1.5 trillion deficit reduction plan in a face-to-face meeting with congressional allies and adversaries.

His chances are squeezed by anti-tax conservatives, by liberals unwilling to cut into Medicare and Social Security, and by a Republican leadership that has dug in against any new revenue after ceding to Obama's demands two months ago for a higher tax rate for top income earners.

On Thursday, two ill-fated proposals aimed at blunting the blame over the cuts ? one Democratic and the other Republican ? failed to overcome procedural hurdles in the Senate. Obama placed the responsibility on Republicans.

"They voted to let the entire burden of deficit reduction fall squarely on the middle class," he said.

The White House is still betting that once the public begins to experience the effects of the $85 billion in across-the-board cuts the pain will be unbearable enough to force lawmakers to reconsider and negotiate. But the consequences of the cuts ?the so called sequester ? will likely be a slow boil. Obama this week said the effect "is not a cliff, but it is a tumble downward."

Indeed, much of the impact won't be felt for weeks or more than a month; others, like possible teacher layoffs, wouldn't take place until the new school year in the fall.

And yet, the next likely showdown ? the expiration of a six-month spending bill on March 27, with its built-in threat of a government shutdown ? will loom before that, meaning that the leverage the White House would hope to have won't materialize until late.

Polls also show that the public is not as engaged in this showdown as it has been in past fiscal confrontations and an NBC-Wall Street Journal Post survey indicates that Obama has lost some ground with the public in his handling of the economy.

Still, White House officials also say they believe Republicans will once again give way to additional tax revenue in part to avoid drastic cuts and in part to win reductions in Medicare and Social Security spending from Obama that they have been unable to get from Democrats before.

"I am prepared to make some tough decisions, some of which will garner some significant frustration on the part of members of my party, but I think it's the right thing to do," Obama told top business executives this week.

Given Washington's entrenched partisanship, Obama's effort could be dismissed as either another failed attempt at negotiations or as simply an effort to lay blame on Republicans for blocking compromise.

The odds aren't with the president.

Many conservatives are willing to accept the automatic cuts as the only way to reduce government spending, even though the budget knife cuts into cherished defense programs. Likewise, many liberals are beginning to embrace the cuts as a way to protect revered big benefit programs that have long been identified with the Democratic Party.

Moreover, many programs for low-income Americans are protected from the immediate cuts while the Pentagon ? whose budget has long been a target of the left ? faces across the board cuts of 8 percent and up to 13 percent in some of its accounts.

More than 20 Democrats in Congress, including veteran Rep. Ed Markey, a candidates for the Senate from Massachusetts, have signed a letter pledging not to cut Medicare, Medicaid or Social Security benefits in efforts to reduce the deficit.

Obama's plan calls for $580 billion in new revenue over 10 years by limiting the value of itemized deductions and certain tax exclusions to no more than 28 percent. That means taxpayers with a tax rate greater than 28 percent would face a tax increase.

While Obama also regularly talks about closing loopholes to gain more revenue, his tax plan would close many corporate loopholes to lower corporate tax rates, not to generate more revenue. He aims to drop corporate tax rates from 35 percent to 28 percent for most corporations and down to 25 percent for manufacturers.

In exchange for new tax revenue and a tax overhaul, Obama has offered to reduce spending in health care programs such as Medicare by $400 billion over 10 years, change an inflation formula for government benefits that would result in lower cost-of-living adjustments for Social Security and other programs, and reduce other spending for total reductions of $900 billion over 10 years.

Those cuts, together with about $2.5 trillion in deficit reduction already achieved over the last two years through spending cuts and a year-end tax increase on taxpayers making more than $400,000 would achieve a $4 trillion deficit reduction target.

Republicans though are unimpressed, and House Speaker John Boehner rejected it when Obama first offered it in December.

"Last year we proposed generating new revenue through tax reform," Boehner said Thursday. "We did that as an alternative to the president's demand for higher tax rates. Ultimately, the president got his revenues and he got it his way through higher rates. Given those facts, the revenue issue is now closed."

At the other end of the spectrum, liberals are seeking to silence White House talk about cutting entitlements.

"They're almost on a daily basis talking about (reducing) Social Security benefits," said Adam Green, founder of the liberal Progressive Change Campaign Committee. "There's no rational or political reason to do so, except some ill-conceived idea that Americans would value a grand bargain, even one that robs their grandparents of thousands of dollars."
