The Gulf of Mexico receives many nutrients from the rivers that empty into it, especially the Mississippi River, causing the Gulfs northern shelf waters to become overly enriched and more susceptible to algae growth.

However, it remains largely obscure whether a significant portion of those nutrients ever leaves the Gulf to impact the chemistry of the North Atlantic Ocean potentially.

It is essential to track the nutrient input from the Mississippi and Atchafalaya River System to the Gulf as those nutrients contribute to harmful algal blooms on the Northern Gulf Shelf.

In a new study, scientists from Florida State University are shedding light on nutrient levels in the Gulf of Mexico. To conduct the study, the team collected and analyzed water samples taken during four different research cruises to the Gulf and the Florida Straits from 2011 to 2018.

This finding is valuable to know, as these ecosystems must harbor the nutrient burden.

Scientists did not found any evidence that nitrate from the Mississippi-Atchafalaya River System is mixing across the Northern Gulf shelf into the Gulf of Mexicos open waters. The findings are consistent with recent modeling work by fellow scientists indicating that 90 percent of Mississippi River nutrients are retained in the near-shore ecosystem, which implies that nutrients from the Mississippi River do not leave the Gulf.

This is the first study that offers isotopic composition measurements of nitrate in the Gulf of Mexico and a new isotopic profile from the Florida Straits.

Scientists then compared water column profiles with prior measurements from the North and South Atlantic and with the magnitude of nitrogen inputs to the Gulf.

Associate Professor of Oceanography Angela Knapp said,The study looked for distinct geochemical signatures of nitrate from the Mississippi River and whether this nitrate made it off the Northern Gulf of Mexico shelf into the deep waters of the Gulf that mix with the Loop Current and left via the Florida Straits to enter the North Atlantic.

This work has important implications for understanding the fate of nutrients from the Mississippi Atchafalaya River System and how to manage human inputs to coastal ecosystems.

What if all of the sudden, the right side of peoples faces on your TV appeared to be melting? What if the right side of your own face seemed like it was melting in the mirror? That is the surprising case of a 59-year-old Portuguese man. A study about him was recently published in the scientific journal Current Biology.

The international study was carried out by researchers from the Faculty of Psychology and Educational Sciences of the University of Coimbra, in collaboration with the Hospital of the University Center of Coimbra, Dartmouth College, and the Massachusetts Institute of Technology.

The man, referred to by the fictitious name Augusto in the published study, has an extremely rare neuropsychological condition called hemi-prosopometamorphopsia only 25 cases are known worldwide. Augusto is unable to visualize faces in a normal way, something that causes him unimaginable suffering.

This condition is usually characterized by the perception of a distortion in the eyes, nose and/or mouth only on one side of the face. These features seem to be falling off, almost as if they were melting. Nothing more than images of faces causes these distortions, says Jorge Almeida, the studys principal investigator and director of the Proaction Lab.

A series of studies with this patient showed for the first time the existence of a step in the processing of faces in which these are rotated and resized to match a pattern. In the process of recognizing a face we are seeing, we compare that face with those we have in our memory. Thus, whenever we see a face, our brain creates a representation of it and aligns it with a model we have in memory, adds the researcher. This is, in fact, the way digital face recognition used by Facebook and Google platforms works.

In addition, with this study it was possible to demonstrate that these representations of faces are present in the two hemispheres of the brain and that the representations of the right and left halves of the faces are dissociable. Thus, this study not only increased knowledge about the functioning of the brain, but also supported with scientific evidence one of the most widely used facial recognition methodologies today.

Like many other patients with hemi-prosopometamorphopsia, distortions experienced by Augusto were caused by a lesion in white matter beams that connect the neuronal areas dedicated to faces present in the left and right cerebral hemispheres, preventing the flow of information between them.

One of the experiments carried out with Augusto was the presentation of images from different perspectives (left profile, front and right profile). Augusto indicated that the eyes, mouth and/or nose of the presented faces appeared to be drooping red areas in the image below. No other deformations were reported when any other non-face images were presented (cars, houses, etc.)

In a second experiment, the researchers presented images of faces in very different forms: the left and right halves of the faces separately, on both sides of the visual field (right and left) and rotated at 90, 180 and 270 degrees.

Regardless of how the faces were presented, Augusto continued to report that the distortions affected the same parts of the face. Even when the face was inverted (mouth upand eyes down), the patient saw the distortions on the left side. It was still the right eye that seemed to be melting, even though in the inverted face it is located on the left side.

When presenting faces at various angles of rotation, we found that only the right characteristics of the face were distorted, even when the face was presented inverted 180 degrees and those parts of the face were on the left side. The only way to explain this result is that when we process faces, we rotate them and create a model centered on the face and not the observer. In this way, the right eye in this face-centered model is always represented as the right eye, even if it is in our left visual field as when we see an inverted face. This model centered on the face is then compared with an existing model, concludes Almeida.

The study, Face-Specific Perceptual Distortions Reveal A View- and Orientation-Independent Face Template, was authored by Jorge Almeida, Andreia Freixo, Miguel Tbuas-Pereira, Sarah B. Herald, Daniela Valrio, Guilherme Schu, Diana Duro, Gil Cunha, Qasim Bukhari, Brad Duchaine, and Isabel Santana.

The Shed pits teenagers against a vampire who has taken up residence in a shedStan and Roxy fight the sinister threat, but do they make it out alive?

Director Frank Sabatella's 2019 horror movie,The Shed, adapts a simple premise with an open ending that left audiences questioning the safety of the heroes: what happened to Stan and Roxy?

The Shedtakes standard-issue vampire movie tropes and tucks them behind a smart, character-driven feature film. Stan (Jay Jay Warren) is an orphan who thinks he's dealing with the normal high school woesbullies, unrequited crushes, and an overbearing grandfatheruntil he realizes that a vampire has taken up residence in the shed on his property. From there,The Shed descendsinto a nightmarish bloodbath when more and more people fall victim to the trapped creature and Stan's best friend, Dommer (Cody Kostro) starts to see Stan's problem as a solution to theirs.

By the film's climax, Stan and his crush Roxy (Sophia Happonen) are fighting to defend his home come nightfall, when the vampireand the new ones he's turnedare on the prowl. While most of the movie takes place during daytime hours, when the vampires are less of a threat, there's still a high body count, action, gore, and shocking moments that lead up to the movie's final shot, where Stan and Roxy's fate is essentially unknown. Here's what happened inThe Shed's ambiguous ending.

Vampire movies and television were a staple of the early and mid-2000s, and while there are many different approaches in dealing with these creatures,The Shed manages to bring something new to the table. The fact that the vampire is trapped in Stan's shed might seem like a no-brainer, but Sabatella's movie explores the very human conflicts that coincide with this unlikely scenario. Stan is unsure of what to do with the creature at first, and his fear keeps him from acting immediately and doing something logical, like burning the shed down. His dog and his grandfather are the vampire's earliest victims, but after he tries to ask his friend Dommer for helpespecially since there's a body on his propertyhe's surprised with Dommer's answer. In Dommer's mind, this terrifying situation is really to their benefit: they can sacrifice their high school bullies to the monster, or use it to threaten them.

This, of course, ends poorly. Dommer's lust for power and revenge gets him turned into a vampire, and the bullies come sniffing around Stan's property right at dusk, looking for their leader Marble (Chris Petrovski), who ended up summarily meeting his end in the shed. Ultimately, Stan and Roxy are the last two standing, and nurse their injuries in a car before Roxy mentions that it's soon to be nightfall again; they think they've seen the last of the vampires, but as the final shot pans out on the trunk of the car, it's apparent that they're not alone. They missed one. It's an unfortunate oversight, but a realistic one insomuch that a movie about a vampire trapped in a shed can be realistic.

Earlier this week, Texas A&M cornerback Elijah Blades announced that he was opting out of the 2020 college football season. It was a bit of a curious move as the NCAA has ruled that this season does not count toward eligibility.

Blades was set to be a senior this coming season but, with the NCAA rule, he still could have returned for a fifth year in 2021 due to this year not costing anybody elibility. Because of that, there did not seem to be a clear reason that the 6-foot-2, 180-pound defender was opting out. In making the announcement on social media, Blades said that he planned to return for the 2021 campaign in Aggieland, so the opt-out did not seem to be in preparation for a transfer, either.

On Thursday afternoon, Texas A&M head coach Jimbo Fisher held his weekly press conference via Zoom. He was asked about Blades' decision and cleared things up a bit.

"I wouldn't say I was surprised (by the decision)," Fisher said. "You wish they were there but you understand the things that are going on and that's between us...Elijah was just coming off a shoulder surgery. He had practiced most of the practices, almost the whole time. We'd give him a little break. He was coming back. He would have been full-speed here shortly. But, there's other issues and things going on."

Texas A&M is entering the season with a battle for the starting job at both cornerback spots. Four players were in the mix in Blades, senior Myles Jones, junior college transfer Brian George and true freshman Jaylon Jones. Blades and the elder Jones are the lone players with experience and both started a year ago. That number is now down to pretty much the three players competing for the two spots.

"It doesn't help depth but, at the same time, some of our younger guys are really playing good and we feel comfortable with what we have," Fisher said.

"There's open competition," he added. "We're getting ready for the first scrimmage this weekend and those guys have all done well and continue to do well."

Blades played in seven games a year ago before missing the remainder of the season with a shoulder injury. He finished his shortened season with 19 tackles, 2.5 tackles for loss, 1.5 sacks and three pass breakups.

In the class of 2019, Blades was a four-star prospect when he signed with Texas A&M as a junior college transfer. Originally from Pasadena, Calif., he played his junior college ball at Arizona Western C.C. Blades was actually a longtime Oregon commit before switching to the Aggies right before the Early Signing Period.

Texas A&M had another member of the secondary opt out this week as well, though he was not expected to be as big a part of the depth chart as Blades. Fourth-year junior safety Derrick Tucker announced on Tuesday evening that he would be foregoing the season.

"I know Tuck's said he's going to step back and do a lot of things for Black Lives Matter, which is tremendous," Fisher said. "Because, like I say, there's things out in the world right now that he thinks are very important and we think are very important and giving him the opportunities to do that."

Tucker played in four games a year ago before asking to be redshirted. The NCAA allows players to see action in up to four games now and still preserve their redshirts and, with Tucker not seeing a ton of playing time, he wanted to save his. While others that made the same request transferred in the offseason, the 6-foot-1, 200-pounder returned to Aggieland this fall.

Tucker actually made seven starts as a true freshman in 2017 after coming in as a four-star recruit out of Manvel, Texas. He was named the SEC Defensive Player of the Week that year after his performance against Ole Miss when he had 14 tackles, a tackle for loss, a forced fumble and an interception. He also had double-digit tackles against LSU. However, Tucker took a step back as a sophomore in 2018. He saw action in 10 games but did not start. He finished the season with 27 tackles and a pass breakup, a year after recording 55 and 5 of those, respectively.

As for both defenders, Fisher says both should be back on next year's roster.

"We expect both those guys back," he said. "There hasn't been anything to the contrary to say they wouldn't be back....We love those guys and we'd love to have them back."

The lone other Aggie to opt out of the season is third-year sophomore quarterback James Foster. The former four-star prospect from Alabama was third on the depth chart a year ago. He is currently in the NCAA Transfer Portal but chose to stay in Aggieland this fall.

With its Wagnerian orchestral soundtrack, exceptionally low camera angles, and sweeping shots of white marble columns reaching up toward the heavens, last weeks Republican National Convention served as an answer to the question, What would happen if the producers of The Apprentice did a remake of Leni Riefenstahls Triumph of the Will?

Which makes sense, given that two of Trumps former reality show producers were brought onboard to help direct the event. The resulting spectacle could not have been more different from the previous weeks Democratic National Convention, which, by contrast, had all the production values of a local cable access show from the late 1970s.

What was more surprising was the music itself. Gone were MAGA rally favorites like the Rolling Stones You Cant Always Get What You Want and Neil Youngs Rockin in the Free World. Was it possible that, for the first time in four years, Trump was finally yielding to the demands of the numerous artists whove railed against his use of their music without their consent?

That question would be answered during the conventions fourth and final day. But first, to put all of this in perspective, its worth taking a brief detour to consider the history of Trumps battles with these musicians and the legal issues surrounding them.

The best-known case is Trumps use of the Stones You Cant Always Get What You Want at the close of rallies in which hes just assured his overwhelmingly white audiences that he will, in fact, get them everything they want and more.

Trump has been doing this for four years now, during which time a sizable portion of his audience must have picked up on the contradiction. So why keep doing it?

One likely reason is that Trump and his followers enjoy nothing more than trolling their perceived enemies. Another is the fact that Trump is as tone-deaf when it comes to music as he is with everything else. This is, after all, the president who taunted Black Americans by asking What have you got to lose?... a question he subsequently directed toward coronavirus victims in an effort to sell them on hydroxychloroquine.

Meanwhile, back in the realm of music, there was the Midwest rally that Trump held just hours after a white racist walked into a synagogue and opened fire on the congregation. While the rest of the nation grieved, Trump got his followers to get up and dance to Pharrell Williams Happy.

Williams lawyer responded with a cease-and-desist order that conveyed his clients outrage:

On the day of the mass murder of 11 human beings at the hands of a deranged nationalist, you played his song Happy to a crowd at a political event, Williams lawyer wrote. There was nothing happy about the tragedy inflicted upon our country on Saturday, and no permission was granted for your use of this song for this purpose.

But Trump, as hes proven time and again, has a fondness for insulting dead people, and that routinely bleeds over into his campaign music. Tom Pettys family decried the use of I Wont Back Down at Trumps June 20 Tulsa rally. George Harrisons estate sent their own cease-and-desist letter after Trump appropriated Here Comes the Sun. The surviving members of Queen, dismayed by his use of We Will Rock You, did the same on behalf of themselves and their late singer Freddie Mercury.

Trump, as hes proven time and again, has a fondness for insulting dead people.

The reason Trump has continued to get away with all this involves the blanket licensing agreements that music licensing organizations like BMI and ASCAP make with political campaigns and the venues in which they hold their rallies.

Both organizations let artists fight their own battles until this past June, when the two organizations unexpectedly warned Trump to stop using You Cant Always Get What You Want, as well as any other Rolling Stones songs, during his rallies. According to BMI, once an artist issues a cease-and-desist letter, any future use constitutes a breach of contract.

And so it was that, on the last night of the Republican National Convention, the gathering of unmasked supporters on the White House lawn were deprived of the upbeat anthems theyd come to know and love.

Still, Trump could not resist showing one last sign of disrespect, which he directed at a deceased artist whose estate and publisher had both turned down the RNCs request to play one of his best-known songs at the convention. During the closing ceremony, the singer Christopher Macchio came out on the White House balcony to serenade the president and his entourage with a semi-operatic set that featured Leonard Cohens Hallelujah, a recorded version of which had also been played moments earlier as fireworks exploded over the Washington Monument.

Apart from its title, Cohens borderline vicious ode to God-knows-what was an inexplicably bizarre addition to a medley that included classical-crossover fare like Ave Maria and Nessun Dorma. This is, after all, a song with lyrics like Ive seen your flag on the marble arch / Love is not a victory march / Its a cold and its a broken Hallelujah.

According to the White House, Trump makes all of the final decisions when it comes to which songs are played at his events. But that doesnt mean he actually listens to all of them.

So what happens next?

For now, at least, Trump has managed to keep from using the Rolling Stones as his walk-off music. Instead, hes replacing it with his fans second favorite rally song, which is, wait for it, the Village Peoples Y.M.C.A. Theres something almost endearing, given the racist and homophobic underpinnings of Trumps campaign, to see MAGA supporters joyfully getting down to the racially integrated and flamboyantly dressed groups ode to intimate male bonding.

But Village People leader Victor Willis is not amused, as he conveyed in a recent Facebook post directed toward Trump:

I ask that you no longer use any of my music at your rallies, especially Y.M.C.A. and Macho Man, following the George Floyd protests and Black Lives Matter marches, he wrote. Sorry, but I can no longer look the other way.

Republican National Convention sheds new light on Trump's use of music without artist consent - Colorado Springs Independent

FORT COLLINS, Colo. (CBS4) As scientists at Colorado State University lead the state in monitoring COVID-19 outbreaks through raw sewage testing, the university confirmed they have seen a spike in coronavirus in their testing of on-campus dormitory wastewater.

Last month experts at the university told CBS4s Dillon Thomas the virus is traceable through raw sewage days before the carriers show symptoms, if they show any symptoms at all.

The university is currently partnering with multiple municipalities from around the state, from Pueblo to northern Colorado, to monitor levels of COVID-19 in raw sewage. By doing so municipalities can better forecast outbreaks of the virus. The same mentality was applied to the Fort Collins campus, where the university is now testing individual dormitories.

A spokesperson for CSU confirmed they have increased testing at three dormitories on the campus after noticing a spike in COVID-19 being shed through waste. They also increased testing among employees who work in the northeast corner of the campus due to a spike in levels in wastewater.

The staff has focused their dormitory testing on three dorms, specifically looking in to one wing of one of the dorms, and two other hallways. The university did not provide information on which dormitory, or building which faculty were in, were the focus of their further testing.

The university has already administered more than 9,700 COVID-19 tests since students returned to campus weeks ago. Most of those, around 7,400, were completed upon move-in by freshmen.

The first College GameDay of the year came on Saturday. The crew had a lot to address; Lee Corso expressed his belief that college football shouldn't be played until Spring 2021, quite a declaration to come on a college football pregame show.

They then addressed the issues of social injustice and racism in the country that have demanded America's attention in the months since we last saw college football on TV. In a very emotional segment, Kirk Herbstreit started to cry when he talked about the injustice the Black community faces in this country and how frustrating it was that there are still people out there who refuse to acknowledge the problems that are deeply embedded in every part of our lives.

This is really something to see. Herbstreit's pain is evident, and the importance of addressing this issue on every national stage is impossible to overstate.

Watch. Listen. Work for change. That's what we have to do, and we cannot relent. Herbstreit reminded us all of that.

(Sept. 3, 2020)Paul Judy calls Oswald Tupancy one of the islands greatest golfers, foremost philanthropists and a bit of a mystery.

I just thought he had such a fascinating history, and its a story I hope all the citizens from Nantucket who benefit directly and indirectly from his (philanthropy) know, Judy said about the subject of his recent book,The Life and Times of Oswald Anthony Tupancy: Golfer, Investor, Benefactor.

Tupancy grew up in modest circumstancesin Detroit and moved to Nantucket in 1928 at the age of 21.

Over the next 50 years he accumulated enough wealth to donate to the Nantucket Conservation Foundation one of the islands most popular open-space properties, Tupancy Links on Cliff Road, as well as establish the Tupancy-Harris Foundation, which over the years has donated millions of dollars to nonprofits across the island.

Book sheds new light on philanthropist Tupancy - The Inquirer and Mirror

Several months ago, a rumor that Josh Duggar lives in a warehouse with his wife and six kids spread like wildfire on social media.

For critics of the Duggar family, the report seemed almost too good to be true.

After all, few celebrities -- and perhaps no reality stars -- are as widely-despised as Josh, who molested four of his sisters and was assisted by his parents in covering the act up for over a decade.

The online legion of Josh haters wanted the news to be true -- wanted to believe the predator was finally paying for his crimes -- but it seemed so unlikely.

He had been getting away with everything his entire life, and it was almost impossible to imagine that justice would be served in 2020, of all years.

But it seems like this hellish trip around the sun has offered us a sort of consolation prize.

Last week, TLC inadvertently confirmed that Josh lives in a warehouse by shooting a scene in an "unused" storage shed.

Viewers were able to match the decor to photos that Josh's wife, Anna Duggar, took at home and posted on Instagram.

It turns out the shed isn't so unused after all -- in fact, it houses a family of eight.

It's a complex situation, and even for those of us who think of Josh as a monster masquerading as a family man, it's hard to celebrate too much.

After all, Josh isn't suffering alone here -- he has a wife and six kids living in the windowless shack right beside him.

Fortunately, the conditions are not unsafe, and there's no reason to believe that Josh's kids are going without proper food or healthcare.

It's still sad, but it's not hard to see how some fans have decided to chalk this up as the latest in a long line of amusing embarrassments for Josh.

Thankfully, the man is unable to defend himself, as he has no social media presence.

However, Josh's long-suffering wife is doing her best to accentuate the positive and send a message to fans:

Our ever growing family might be poor, she seems to be saying, and yes, I'm married to a child molester -- but gosh darn it, we're rich in spirit.

Anna doesn't post pics of the entire family very often but she posted the photo below after church services on Sunday:

"This photo definitely belongs in the expectation vs. reality filebut we had fun trying to take a family pic at church today," she captioned the photo.

"Hope yall have had a wonderful Sunday!"

With the little one up front picking his nose, this is probably not the kind of pic that Anna would have posted under normal circumstances (the Duggars aren't known for their sense of humor).

But she's desperate to do a little image re-building these days following the latest humiliation

Of course, as many commenters have pointed out, the photo was very conspicuously not taken outside Josh and Anna's home.

In fact, Anna has never posted the exterior of their warehouse -- it seems she might not be ready for that particular conversation.

We can't say we blame her.

The Antietam battlefield (Getty Images).

SHARPSBURG, Md. - A long-forgotten Civil War map has recently been rediscovered, shedding new light on the bloody aftermath of the battle of Antietam.

Some 23,000 soldiers were killed, woundedor missing following the battle on Sept. 17, 1862, which has been described as the bloodiest day in American history.

The S.G. Elliott Burial Map shows where 5,800 Americans were buried in temporary graves. The map, which is in the collection of theNew York Public Library, was discovered by researchers looking for information on the battle of Gettysburg.

The S.G. Elliott Burial Map shows where 5,800 Americans were buried in temporary graves.

The map was digitized two years ago, but until its recent discovery in the librarys archives, it was unknown to experts. Earlier this year, researchers from the Adams County Historical Societyin Gettysburg, Pa., found the map when they were looking for information on mapmaker Simon G. Elliott.

After discovering the map, the researchers notified National Park Service staff at Antietam National Battlefield.

The detailed map, like a counterpart that Elliott made following the battle of Gettysburg, was likely made in autumn 1864. Although historians are still performing analysis of the map, more than 5,800 soldier burials are individually recorded, typically in groups associated with a particular regiment, also noted on the map, explains the American Battlefield Trust, in astatement. Field burials often saw soldiers interred by comrades, very close to where they fell, meaning that the map confirms the locations where units were engaged on the field.

Whereas 18 soldiers were identified by name on Elliotts Gettysburg map, more than 50 were identified on the Antietam map, according to ACHS Executive Director Andrew Dalton.

Looking at this map, there can be no doubt in the truth of the statement that a battlefield is hallowed ground, made so by the blood of soldiers, said American Battlefield Trust President Jim Lighthizerin a statement. The landscape at Antietam was turned into one vast cemetery, sacred to the memory of those who lost their lives in the struggle.

Although most of the interments have been moved off the battlefield to Antietam National Cemetery, the map is nonetheless an incredible historical document.

The Elliott map shows that dozens of men were once buried in the immediate vicinity of the national parks visitor center, said theAmerican Battlefield Trustin its statement. The 461 acres that have been protected by the American Battlefield Trust show evidence of more than 600 burials.

Antietam was a crucial battle in the Civil War, ending the Confederate Army of Northern Virginias first invasion of the North. President Abraham Lincoln also issued the preliminary Emancipation Proclamation in the wake of the bloody clash.

The map effectively unlocks new aspects of the battle and its aftermath.

This discovery reveals truths about the Battle of Antietam lost to time, said American Battlefield Trust Chief Historian Garry Adelmanin the statement. Its like the Rosetta Stone: by demonstrating new ways that primary sources already at our disposal relate to each other, it has the power to confirm some of our long-held beliefs or maybe turn some of our suppositions on their heads.

Civil War sites across the U.S. regularly offer fresh glimpses into the bloody conflict. Earlier this year, for example, an artillery shell from the Civil War wasdiscoveredin downtown Charleston.

ACivil War-eragravestone linked to the infamous Quantrills Raid wasdiscoveredlast year in a Kansas forest.

Also in 2019, a Civil War cannonball wasdiscoveredlodged in a walnut tree at a historic house in Independence, Mo.

Earlier in the year, archaeologists in Delawarelocatedthe gravestone of a Civil Warsoldier that may provide a vital clue in uncovering a long-lost African-American cemetery.

In 2018, the remains of two Civil War soldiers werediscoveredin a surgeons burial pit at Manassas National Battlefield Park in Virginia. Also in 2018, a vacationer on a North Carolina beachcaptured drone footageof a Civil War-era shipwreck.

In 2017, forensic linguists said they hadlikelyunraveledthe mystery surrounding a famous Civil War-era letter longbelieved to have been written by Lincoln.

In 2015, the remains of a Confederate warship wereraisedfrom the Savannah River in Georgia. The following year, the wreck of a large iron-hulled Civil War-era steamer wasdiscoveredoff the coast of North Carolina. The ship, which was found off Oak Island, N.C., was tentativelyidentifiedas the blockade runner Agnes E. Fry.

The last person to receive a Civil War-era pensiondiedin North Carolina last month, according to reports.
