Stewart on 'Daily Show': 'I wanna come home!'
TV 
31 minutes ago
Jon Stewart is in the Middle East working on his first directorial project, but the host of "The Daily Show" took a few minutes to check in on his program via Skype Thursday.
Temporary host John Oliver told Stewart that not much had changed on the show since the now-director started his 12-week leave of absence.
"The only key things are we play softball against the Mets on Monday, and Bruce Springsteen comes to play every Tuesday night," Oliver jested. "We didn't think they'd be things you'd enjoy."
Turns out they are things Stewart would enjoy.
"What?! That's my favorite musician! What?! I wanna come hoooome!" Stewart jokingly cried.
Earlier, a newly bearded Stewart told Oliver that he was "doing a phenomenal job" holding down the fort, but that he wasn't tuning in every night.
"I don't watch it all the time because it's too weird," Stewart said. "It's like watching someone have sex with your wife's desk."
The comedian said he missed his staff "like crazy cakes." Though he's enjoying his work on "Rosewater," an adaptation of Newsweek reporter Maziar Bahari's best-selling memoir "Then They Came For Me," he called the experience "weird as hell."
The film and memoir tell the tale of Bahari's arrest by the Iranian government in 2009 while he was there covering the election results. He was tortured for 118 days. After his October release, Bahari appeared on "The Daily Show" in late November to share details of his captivity.

Los Angeles puts ridesharing companies on notice, demands local permits
Someone didn't get the memo, apparently. Despite California's Public Utilities Commission giving ridesharing services the all clear on a statewide level, Los Angeles' Department of Transportation has sent cease-and-desist warnings to Lyft, Sidecar and Uber, claiming that all three are breaking local laws by operating without city permits. Drivers could face arrests and lose their cars if they keep serving customers, according to the notices. Not surprisingly, the ridesharing firms have a very different opinion. Uber tells Engadget that it's operating a limousine-like service which only needs PUC permission to operate, and Lyft says it's talking with the Mayor's office to resolve what it believes is a "state issue." For now, we're at an impasse -- let's just hope that Los Angeles follows in New York's footsteps and tries to reach a happy medium.

Sony's SBH52 Smart Bluetooth clip acts as your secondary handset
HTC may have its Mini Bluetooth handset, but Sony thinks such implementation works best as a big clip without the numeric pad. Dubbed the SBH52, this splashproof device comes with FM radio, a headphone jack plus a small OLED display to show caller ID and text messages, so in a way it's similar to its predecessors. What's new is that you now get NFC as well as an earpiece -- the latter lets you use the clip as a mini phone. Expect to see this on the shelves in Q3 this year.

Israeli: Detention center for Africans a 'prison'
JERUSALEM (AP) ? Hundreds of African migrants are languishing in a desert detention center in southern Israel, where families may only meet once a week and where women and children sleep in a prison-like compound, according to lawmakers who caught a rare glimpse.
The visit to Sahronim center by a parliamentary delegation has allowed a look into the facility that plays a key role in Israel's attempt to stem the tide of thousands of African migrants who have crossed the long desert border with Egypt to the Jewish state in recent years.
"It's not a camp. It's a prison," said Michael Rozin, an opposition lawmaker with the dovish Meretz party. "You have guards. You are not free do what you want. These people are not criminals. Their crime is asking for a better life."
Israel, like other developed countries in Europe and around the Mediterranean, is a magnet for asylum seekers and economic migrants. Though the physical conditions at the Israeli detention camp appear harsh, large numbers of refugees face much worse around the region.
Most of the 55,000 African migrants who made it to Israel over the past decade claim they were escaping forced, open-ended conscription in Eritrea or war in Sudan. Critics counter that most are job seekers attracted to Israel's wealthy economy and plentiful jobs in hotels, restaurants and cleaning.
As their numbers swelled, they began to be seen as a threat to Israel's Jewish character. Most live in Tel Aviv slums, while their legal status remains in limbo. The government is trying to expel some and find alternative refuge for others.
Over the past year, Israel mostly halted the influx with a fence along the Egyptian border.
Those who have trickled in since, some 1,600 people, have been sent to Sahronim in the Negev desert, roughly an hour's drive from the city of Beersheba.
Israeli authorities say a detention facility discourages migrants by denying them a livelihood, and claim conditions at Sahronim are adequate.
"There is no doubt one of the reasons we had such a flow of illegal economic migrants into Israel was because the economy was such a magnet," said Israeli government spokesman Mark Regev. "It was important for us to deal with that magnet."
Lawmaker Rozin said detaining migrants in prison-style facilities is inhumane, even though she and other advocates said they are not mistreated, and they receive adequate medical care and food.
Prison authorities allow few visitors, and reporters are banned. Lawmakers are allowed to request visits.
Many of the 1,400 men live in tents holding about 10 people each. Fences separate them from the 200 women and some 11 children, housed in a low-slung building around a courtyard. Families are allowed to meet only on Thursdays for several hours, though they can request more time.
Another section holds migrants who are convicted felons or who are suspected of committing a felony, Rozin said.
The children have a kindergarten and adults may take courses, she said. They are counted every day by guards and barred from leaving, underscoring the sense of imprisonment, she said.
One woman who was released to a shelter in February after eight months in Sahronim described a bleak existence.
"The cells have steel doors," the woman, whose name was redacted, said in testimony to the advocacy group, Hotline for Migrant Workers. She said women slept 10 to a room in bunk beds. "Sometimes in the morning a little light comes in, but one cannot feel the sun."
A video smuggled out of Sahronim by a member of the lawmakers' delegation this week and given to Israeli media showed men standing behind fences.
"Prison, prison, prison, all the time," said one man who said he'd been there for 15 months but did not give his name. One woman said her children had nothing to do beyond two hours of daily activity.
Israel's policy can be compared to that of European countries. In France, officials expel 30,000 migrants each year, and authorities search immigrant neighborhoods to find others. In 2011, over 50,000 migrants sought asylum in France; only about one-fifth of the applications were granted. Countries like Greece, Cyprus, Malta, Italy, which face the largest waves of migrants, also hold them in crowded detention centers that are widely criticized by rights groups.
For decades in Europe, incarceration has been a politically popular move as communities often feel overwhelmed by culturally different immigrants, often mostly young men.
In the region, Lebanon and Jordan have each absorbed some half million Syrian refugees fleeing the civil war in their country. In Jordan, many live in miserable desert refugee camps near the border.
In Israel, only 136 people have left Sahronim since last year, said Sigal Rozen of the Hotline for Migrant Workers.
Women identified as trafficking victims are sent to shelters. Egyptian smugglers often torture or rape women on their journeys.
African migrants designated as refugees may be released, but advocates say Israel has dragged its feet on thousands of refugee applications it has received. It has ruled on just 17 cases, rejecting them all.
Israel cannot deport Eritreans, who make up the bulk of African migrants, because they risk persecution by their government. They can be held for up to three years, but some have left following court petitions, Rozen said.
It also doesn't deport Sudanese migrants, because Sudan is an enemy state. Advocates said Sudanese migrants are expected to stay in Sahronim, under pressure to leave to third countries.
In recent months, officials quietly repatriated hundreds of migrants to newly independent south Sudan. Also, early this month, Israel said it found a third country that agreed to accept African migrants. It won't identify the country, and it's unclear when anyone will be transferred.
About 530 Sudanese men have volunteered to accept Israeli financial assistance to be deported from Sahronim, according to Sara Robinson of Amnesty International Israel. Robinson said they are harassed into going home via third countries that may be less welcoming or even dangerous.
"The deportations can't be considered voluntary," said Robinson. "If they were held in detention, and they can be held indefinitely, and that's your other option, we have serious concern about their free consent."

Reinventing The Games Console Half Way Won't Work - TechCrunch
Editor?s note:?Tadhg Kelly is a veteran game designer, creator of leading game design blog?What Games Are?and creative director of Jawfish Games. You can follow him on Twitter?here.
In some ways you?ve got to feel bad for Microsoft. The company has spent years trying to find ways to expand its Xbox idea. It put together a very interesting camera peripheral that many people bought into, but not too many games. It?s tried, on several occasions, to use the games console as a way to win access into the living room. Yet now it?s at the point of having to roll back many of its big ideas because the market reacted so negatively. The company has run into a hard truth: In the minds of the market ?console? means something specific, and is not inclined to expand its thinking.
In essence what Microsoft wanted to do was similar to what Apple did for phones. Long before iPhones there were many years of terrible feature phones. They had Java games, shambolic web interfaces and data plans that charged per megabyte. They?stuck resolutely to sticky keys and small screens, and at best some of them had styluses that pretended to be able to recognize handwriting.?Apple managed to leapfrog that mess by reinventing how it controlled, how it looked and what it felt like. Mobile phones went from being cellular devices to something else, something with sexy touch-screen effects and whatnot, and that in turn opened the door to many other innovations.
That, in essence, was Microsoft?s big idea with Kinect. If the company could redefine control to be much broader than stuffy old joypads, then that opened the door to lots of other avenues. In a sense it was trying to take ?console? into the realm of ?smartconsole? but it had an unwillingness to really go for that. Like Sony and Sega before it, Microsoft has attempted to achieve its vision by expanding the metaphor of what ?console? is supposed to mean rather than defining a new type of product from the ground up. And the market has yet again said no.
Unlike in the computing space where one machine acts as arbiter and translator of all content toward multiple screens, the living room has never really been able to unify. We have several smaller devices that all plug into one big screen. And often they have duplicate functions.?The games console seems like it should solve that. It should be a point of access for content and functionality, roles already filled by computers but in the living room.?So much more could be brought to the living room?if only the audience would get behind that idea. Throw out all your confusing boxes, it seems to say. Bring back some sanity to your life. One box to rule them all and make your life elegant.
Yet no company can really get there. No one company can strike deals with all cable-box makers to essentially cut them out of a key part of their value chain. Nobody is yet able to convince television manufacturers to get behind one standard control method. And since that means there will always be fragmentation,?players really just want consoles to play games. They view consoles as essentially gaming CD players, and preferably cheap ones at that, and steadfastly refuse to buy into the bigger picture.
Their resistance is with good reason:?Transitioning from cheaper many-box to expensive one-box means giving up a lot. It means forfeiting the chance to play games on other systems. It means disconnecting from a pre-existing media service and converting or dumping a lot of material in the process. (Could you ever see iTunes on your Xbox?) The argument has not yet been made strongly enough to the market that the trade-off is worth doing. While smartphones show that dramatic evolution is possible,?a platform holder like Microsoft needs to go much further than it already has if it?s going to change how gamers think.
Several commenters have lamented that Microsoft?s recent reversal on DRM is caused by players being short-sighted, putting immediate value (used games) ahead of long-term potential gains (digital connectedness). To me this reflects a key dissonance.?It?s rare that the market gets educated, and instead much more common that it gets fixated on an idea of what a product category is. It hears ?PC? and it thinks ?powerful desktop computer.? It hears ?console? and it thinks ?shiny games deck.? It sees one sort of trying to act like the other and resists. No no, it says. The device is supposed to be like this.
Even though every PC, smartphone and tablet in the world has a front-facing camera, for example, the market finds something weird about consoles doing likewise because that doesn?t seem to add much to what it believes??shiny games deck? is supposed to be. Even though Nintendo has a great idea for how second screen gaming could work, the market fundamentally regards it askance. A shiny games deck is supposed to be about joypads and such. The tribe only understands ?console? as one thing and is only really interested in features that bolster that vision. All else is viewed with suspicion.
There?s some kind of smart-TV idea trying to be born at Microsoft, an interesting technology which seems just out of reach. There?s something to its Minority-Report-esque idea of swiping, swishing and talking to your television. There?s some notion in the middle of that with tablets and interactions and second screens.?But to get there needs a deep reinvention, and the road toward it does not lead through changing everyone?s minds about the meaning of ?console.? Instead it needs to be a new product, even a whole new category, and its adoption has to go slow.
Rather than adapting a product into something that is complicated, confusing and suspicious, the right approach would be to create something new. One example would be a Kinect standard that could be licensed to television makers and integrated into sets. A standalone camera, irrespective of gaming, that perhaps makes all sorts of remote control tasks easier. And not called ?Xbox? at all. Not called ?console? either.?Or, if the vision mandates that gaming still be involved, a gaming deck that gets beyond the joypad.
Much as the iPhone managed to sell itself by walking away from keypads, arguably the gaming machine that moves beyond ?console? as a product category needs to move beyond the joypad. This is very hard to do. Nintendo almost managed it with Wii before running out of steam and then trying to create a joypad/tablet combo that few people really like.?Kinect tried too, but gestural games are somewhat limited in their scope. Perhaps through SmartGlass or some haptic variant of that in combination with Kinect, Microsoft could get us all into the idea of a new product category like ?smartconsole.?
Or maybe the reason that this product struggles to come to life is simply that there is no place for it. There isn?t anything fundamentally wrong with the games console as a device.?If you like to shoot stuff, jump on platforms, race, and play sports or roleplaying games, the console form factor that we have right now does that. All of the sector?s problems are about how it runs as a business rather than a form factor (which is why microconsoles are a big deal, as they primarily innovate on the business).?Much like the computer or the car, the form factor for doing all those things has not significantly changed in 30 years ? and there?s precious little need for them to.
Blaming the market is all well and good, but there?s no reason for it to change its idea about what a games console is.?And that?s a hard truth. That?s the sort of truth that makes games executives depressed. That?s the kind of truth that, after years of working on grand visions game makers often realize (and become bitter about) that they have to lower themselves back down into the muck. Rather than change the fundamentals the market consistently tells game makers to lean in. Make it bigger. Make it better. Make it play well. Make it feel right. Make it cool. Make it, you know, a great game. That?s all the gaming market cares about, and as yet no one?s made a compelling case for it to think differently.

Supreme Court 2013: The Year in Review
Does today?s ruling mean that schools should keep doing what they?re doing? Photo by Molly Riley/Reuters
Well, we have the kind of anticlimactic ruling from the Supreme Court, on affirmative action that leaves the big question for another day. In a 7-1 ruling (Justice Elena Kagan sat this one out), the court sent back to the lower courts Abigail Fisher?s challenge to the admissions policy of the University of Texas, Austin. Fisher is the white plaintiff who says she didn?t get admitted as an undergraduate because UT Austin considers race, as one factor among many, in admitting part of each entering class. She didn?t win, but neither did UT. Instead, the court made it somewhat harder for schools to defend race-based preferences in admission?but not impossible. Now schools have to show that ?no workable race-neutral alternatives would produce the educational benefits of diversity.? In other words, that the use of race in admissions is a last resort. So, affirmative action is still allowed, and the basis for that hasn?t changed?the goal remains diversity. But lower courts shouldn?t ?accept a school?s assertion that its admissions process uses race in a permissible way.? Instead, courts should give ?close analysis to the evidence of how the process works in practice.?
The key is that Justice Anthony Kennedy wrote the majority opinion, and as usual, Justice Kennedy made clear that he has some doubts about the race-based preference in front of him, but he?s not ready to shut the door entirely on the whole enterprise of increasing diversity. Justice Clarence Thomas, on the other hand, is ready to slam that door once and for all. That?s what his separate opinion is about. No one signed on to it, though, because Abigail Fisher and her lawyers didn?t ask the court to reconsider whether affirmative action is at odds with the Constitution?s guarantee of equal protection?in other words, to find that white university applicants have a constitutional right against reverse discrimination. So Justice Kennedy just says, ?there is disagreement? about whether the court?s 2003 ruling, about the University of Michigan, allowing affirmative action to continue ?was consistent with the principles of equal protection in approving this compelling interest in diversity,? and leaves it at that.
I?m going to post more on this later today, but for now, a few questions. Does today?s ruling, which is kind of a punt, mean that schools should keep doing what they?re doing? Or should they read the writing on the wall, assume that the court will soon take the next step and ban the use of race in admissions, and begin to shift, for diversity?s sake, to an admissions policy that concentrates on admitting more low-income students? The court has already decided to hear a case next term about whether it was constitutional for Michigan to bar racial preferences?a case that?s a mirror of Abigail Fisher?s. Michigan?s ballot initiative, passed in 2006, says that the state?s public universities?"shall not discriminate against, or grant preferential treatment to, any individual or group on the basis of race, sex, color, ethnicity, or national origin in the operation of public employment, public education, or public contracting." The appeals court in the Michigan case?the U.S. Court of Appeals for the Sixth Circuit?has twice struck down Michigan?s law, saying it?s unfair to minorities. Both rulings were split, though, 2-1 and 8-7. What, if anything, does today?s ruling from the Supreme Court suggest about the outcome of this new case next year? I would say nothing directly, but I bet the court?s conservatives plus Justice Kennedy uphold Michigan?s law. And with 10 states now banning affirmative action, that will matter a great deal in the long run for how colleges do admissions.
And what did you make of Justice Ruth Bader Ginsburg?s interesting and lone dissent? Ginsburg is the only justice who would have approved UT Austin?s admissions policy. She likes it, she said, because it?s transparent: The university ?is candid about what it is endeavoring to do: It seeks to achieve student-body diversity,? she writes. Take away overt consideration of race as a factor in admissions, she warns, and you will just drive this practice underground. That?s an implicit critique of some class-based affirmative action programs, which arguably use class as a proxy for race. But is this kind of substitution?admitting more African-American and Hispanic students through preferences for low-income students?actually a bad thing?
More soon, once I digest Justice Clarence Thomas? concurring opinion calling for an end to affirmative action entirely.

Boston, MA A new discovery about how cells move inside the body may provide scientists with crucial information about disease mechanisms such as the spread of cancer or the constriction of airways caused by asthma. Led by researchers at Harvard School of Public Health (HSPH) and the Institute for Bioengineering of Catalonia (IBEC), investigators found that epithelial cellsthe type that form a barrier between the inside and the outside of the body, such as skin cellsmove in a group, propelled by forces both from within and from nearby cellsto fill any unfilled spaces they encounter.
The study appears June 23, 2013 in an advance online edition of Nature Materials.
"We were trying to understand the basic relationship between collective cellular motions and collective cellular forces, as might occur during cancer cell invasion, for example. But in doing so we stumbled onto a phenomenon that was totally unexpected," said senior author Jeffrey Fredberg, professor of bioengineering and physiology in the HSPH Department of Environmental Health and co-senior investigator of HSPH's Molecular and Integrative Cellular Dynamics lab.
Biologists, engineers, and physicists from HSPH and IBEC worked together to shed light on collective cellular motion because it plays a key role in functions such as wound healing, organ development, and tumor growth. Using a technique called monolayer stress microscopywhich they invented themselvesthey measured the forces affecting a single layer of moving epithelial cells. They examined the cells' velocity and direction as well as tractionhow some cells either pull or push themselves and thus force collective movement.
As they expected, the researchers found that when an obstacle was placed in the path of an advancing cell layerin this case, a gel that provided no tractionthe cells moved around it, tightly hugging the sides of the gel as they passed. However, the researchers also found something surprisingthat the cells, in addition to moving forward, continued to pull themselves collectively back toward the gel, as if yearning to fill the unfilled space. The researchers dubbed this movement "kenotaxis," from the Greek words "keno" (vacuum) and "taxis" (arrangement), because it seemed the cells were attempting to fill a vacuum.
This new finding could help researchers better understand cell behaviorand evaluate potential drugs to influence that behaviorin a variety of complex diseases, such as cancer, asthma, cardiovascular disease, developmental abnormalities, and glaucoma. The finding could also help with tissue engineering and regenerative medicine, both of which rely on cell migration.
In carcinomas, for instancewhich represent 90% of all cancers and involve epithelial cellsthe new information on cell movement could improve understanding of how cancer cells migrate through the body. Asthma research could also get a boost, because scientists think migration of damaged epithelial cells in the lungs are involved in the airway narrowing caused by the disease.
"Kenotaxis is a property of the cellular collective, not the individual cell," said Jae Hun Kim, the study's first author. "It was amazing to us that the cellular collective can organize to pull itself systematically in one direction while moving systematically in an altogether different direction."

Picture Perfect Weather Offers Hope To Shore Town Merchants

SEA ISLE CITY, N.J. (CBS) ? The first weekend of summer brought picture perfect weather, which lured large crowds to the Jersey Shore.
?May I see your beach tag,? says Carol, a tag inspector in Sea Isle City. It?s been a busy weekend for her. ?It?s been beautiful since Thursday. We couldn?t ask for more pleasant weather.?
The nice weather is turning around a season that got off to a slow start. That?s a welcome change for Chantel Smith. She opened The Perfect Brew Coffee House and Cafe along the beach in Sea Isle City in May.
?The weekends have been slow because of the rain and it?s been cold,? Smith says, ?but every beautiful day, people are flocking to the beach.?
Including Butch and his family, who decided to take a day trip to the shore.
?It?s nice and cool, the sun is out, there?s not a cloud in the sky,? says Butch. ?So we?re really excited.?
But the weather hasn?t cooperated for much of the season.
?The weather has been kind of crazy on the weekends, but the last couple days have been great,? says Robert Heide, who has owned Touch of Fashion for seven years.??Memorial Day was a little iffy with the weather, but we?re getting there. We?re getting better. [There?s] a lot of hope and we?re looking for a great season.?
Many merchants say if this turn around in the weather continues, sales will be a ?shore? thing.

Religion plays irreplaceable role in society, Archbishop Lori says ...
This is a syndicated post from CNA Daily News. [Read the original article...]
Baltimore, Md., Jun 22, 2013 / 10:06 am (CNA/EWTN News).- Opening the 2013 Fortnight for Freedom, Archbishop William E. Lori of Baltimore emphasized the unique contribution that religion brings to society, warning that it must be protected and allowed to flourish.
?Faith enriches public life not only by the magnitude of its services but by the qualities of mind and heart, by the values and virtues, it brings to the task,? said Archbishop Lori.
He warned that while religious organizations and individuals provide vital services for the common good, ?our government is taking from what belongs to God by state-sponsored attempts to force the Church to compromise her own teachings as the price to be paid for serving the wider community.?
Archbishop Lori, who chairs the U.S. Bishops? Ad Hoc Committee for Religious Liberty, delivered the homily at a June 21 Mass at the Basilica of the Assumption of the Blessed Virgin Mary, the nation?s oldest Cathedral, in downtown Baltimore, Md.
The cathedral was packed with members of the faithful who had come from both Maryland and from other states across the country to attend the opening Mass of the Fortnight for Freedom. They welcomed the archbishop?s homily with a standing ovation.
The Fortnight for Freedom ? currently in its second year ? is a two-week period of prayer, education and action for a greater respect for religious liberty both in the U.S. and abroad.
Growing threats to religious freedom prompted the U.S. bishops to call for the first Fortnight for Freedom last year. Among these threats is the upcoming Aug. 1 deadline when religious organizations must comply with the controversial HHS mandate, which requires employers to facilitate insurance coverage for contraception, sterilization and some drugs that can cause early abortions, even if such cooperation violates their firmly-held religious beliefs.
Other religious liberty concerns raised in past months include attempts to redefine marriage and threats to freedom of religious activity in the realms of health care, humanitarian aid and immigration.
Archbishop Lori explained that ?the Church does not have two wings: a ?faith and worship? division on the one hand, and a ?service? division on the other.? Rather, he said, ?what we believe and how we worship gives rise to public service.?
Acts of service such as education, health care and aid to the poor are not a separate branch of the Catholic faith, he stressed, but ?these activities are part of our baptismal DNA as Catholic Christians.?
?No wonder we shudder, no wonder we react so strongly, when governmental authority tries to slice and dice our Church by separating in law and policy our houses of worship from our charitable, healthcare and educational institutions on the score that the latter are somehow less religious than our churches.?
In the attempt to impose various restrictions on faith-based action and belief, ?Caesar is taking from what belongs to God,? Archbishop Lori said.
In its infringements on religious freedom, ?our government is not only taking what belongs to God; it is also taking from what belongs to human dignity and the common good,? he continued.
?For by imperiling religious freedom, all human rights are put at risk.?
The archbishop explained that rights such as ?the right to life, freedom of religion, freedom of speech and freedom of assembly ? are linked, and these rights are not granted to us by the State but by the Creator.?
Faith is a source of values that lead to deeds which benefit the common good, he stated.
?Through faith we understand that every person is called to share God?s life,? Archbishop Lori observed. ?Through faith we see more readily what a truly just and humane society should be and we receive the strength we need to build a true civilization of truth and love.?
Therefore, he stressed, religious belief benefits the public square ?not only by the sheer magnitude of the humanitarian services it offers but by its witness to Christ Jesus, its witness to those moral truths and values without which democracy cannot flourish.?
The archbishop also explained that the maintenance of religious freedom is important not only to Christians in America, but to all believers of all faiths across the entire globe.
?We continue to live in an age of martyrs ? when believers, not just Christians, are being persecuted for professing and practicing their faith ? when believers are tortured and killed because they are believers, in places like Iran, Iraq, China and Nigeria.?
?Let us keep the flame of faith and the flame of freedom burning brightly not only for our children and our children?s children,? Archbishop Lori entreated, ?but also for the sake of these persecuted believers who see in our form of government and in our great land a beacon of hope.?

Moritz Legal Information Blog: Copyright, Descendible Property, and ...
Copyright is property, the owner of which can transfer it by will. In other words, you could inherit the copyrights in the paintings of your great great uncle Van Gogh, even though Uncle Van Gogh may bequeath the actual paintings to Cousin Mildred. The rights can also be transferred to an entity, like a nonprofit or a corporation.
This can present problems (both legal and emotional) when the new copyright owner licenses the works in a way someone else (e.g., a family member) does not like. For example, if you authorize Company A to market their guns and cigarettes using Uncle Van Gogh's paintings, Cousin Mildred may be devastated, but there may not be much she can do about it.
Such are the issues with the estate of Anne Frank and her diary. For years, parties have been fighting over her legacy through copyright litigation and other legal disputes, and the issue has arisen again. For a brief history, check out the following stories:
