It's official: journey brown's 722 yards in national record book, share this article.

The Meadville (Pa.) football rushing attack and back Journey Brown are now officially in the national high school record book.

Through the Pennsylvania Interscholastic Athletic Association, the National Federation of State High School Associations has verified that Meadville posted 1,004 rushing yards in its 107-90 victory against DuBois and that Brown ran for 722 yards, according to Chris Boone, from the NFHS.

The 1,004 yards is a national record. The 722 rushing yards ranks second.

Here is a look at the page that includes Brown on the Federation web site:

Boone said for records to be included the school needs to supply an application that the state association needs to verify before the records are included.

The PIAA is awaiting word from DuBois about its records from that game. DuBois sophomore QB Matt Miller threw for 787 yards and 10 touchdowns in his first varsity start. That yardage when confirmed would be a national record.

Meadville (Pa.) RB Journey Brown scores 10 TDs in team's 107-90 win

— -- DUBOIS, Pa. -- Journey Brown took a journey all over a western Pennsylvania football field Friday night.

Brown, a running back for Meadville High School, broke the state record for rushing yards in a game, running for 722 yards and 10 touchdowns to help his team outlast DuBois 107-90.

Brown had 30 carries for the Bulldogs and approached the national high school rushing record of 754 yards, set by John Giannantonio of Netcong, New Jersey , in 1950.

"I'm tired," Brown told The Meadville Tribune . "I'm real tired. But it doesn't matter. I came to play for the team, not myself."

Meadville coach Ray Collins was more effusive in his praise of Brown's performance.

"He was absolutely unstoppable," Collins told the Erie Times-News . "He would hit a seam and would be gone. He ran away from the DuBois defense all night long. They were playing tough, but he was making moves out there and stutter-steps and cutting back.

"Journey was even cramping up in the second quarter, but he kept stretching and hydrating to get back in the game," Collins said. "He'd get in there and just take off. He was just in the zone."

Last week in a 28-7 victory over Fairview -- a game called at halftime because of lightning -- Brown had 151 yards and two touchdowns on 12 carries.

Also in Friday night's game, DuBois quarterback Matt Miller, a sophomore making his first start, piled up more than 500 passing yards by halftime and finished with 741, a Pennsylvania record for passing yards in a game, and 10 touchdown passes in the losing effort.

The national record for passing yards is 764, set by David Koral of Pacific Palisades, California , in 2000.

Pa. high school football game ends 107-90, RB goes for over 700 yards

By dani bostick | sep 11, 2015.

A Pennsylvania high school football game ended with a ridiculous score and running back Journey Brown went off! 

Pittsburgh sports director Bob Pompeani out of KDKA TV reported some incredibly astounding stats coming out of the Meadville High School vs. DuBois High School game in Pennsylvania.

WHAT A NIGHT most amazing HS game ever. Journey Brown 10 TD almost 800!!! Yards rushing for Meadville vs DuBois Its 105-82!!! — Bob Pompeani (@KDPomp) September 12, 2015

First, the 107-90 final score would seem better suited to a basketball game. Or, a football game during which neither defense showed up.

107-90 Meadville wins MEADVILLE RB Journey Brown 720 yds 10 touchdowns. Second most yards ever in one game by one player. Most ever 754. — Bob Pompeani (@KDPomp) September 12, 2015

Second, 720 yards? In a single game? Yes. Meadville Bulldogs junior running back Journey Brown ran for over 700 yards, after his breakout 2014 season in which he rushed for 1,651 yards. That means in a single game the 5’11”, 180-lb back rushed for nearly half of his 2014 total yardage.  His 10 touchdown total in Friday’s game is also nearly half of his 22-touchdown total for the entire 2014 season.

Last week in Meadville’s season opener against Fairview, Journey Brown rushed for 109 yards on 10 carries and had two touchdowns.

According to MaxPreps.com, Journey Brown is ranked 3,913 nationally and 165 in the state of Pennsylvania. Brown’s performance tonight was so exceptional that he was only 34 yards shy of the most yards in a game by a single high school player.

A heart condition forces Penn State running back Journey Brown out of football for good

Brown, the Nittany Lions’ leading rusher last season following his 202-yard performance in the Cotton Bowl, was diagnosed in early September. Second opinions confirmed that he could not play again.

Penn State’s Journey Brown, a redshirt junior whose sensational late-season performance in 2019 vaulted him to consideration for national awards in the 2020 preseason, must retire from football because of a heart condition, head coach James Franklin announced Wednesday night.

In a statement he released on his Twitter account, Brown identified his ailment as hypertrophic cardiomyopathy, where abnormal genes in the heart muscle cause the walls of the heart chamber to become thicker than normal, reducing the amount of blood taken in and pumped out to the body with each heartbeat.

Franklin said Brown was first diagnosed with the condition in early September. He said internal testing and second opinions confirmed what doctors at Penn State had thought all along.

“Journey Brown will no longer be able to play football,” he said. “It was discovered through a routine COVID-19 test, although it is not COVID-related. We’ve been working through this and dealing with this as a team. Journey’s one of the most popular and respected players on our team. The entire organization has rallied behind Journey and his family. We need Nittany Nation to do the same, as I know we will.

“Journey’s handled this unbelievably well and I know he’ll be extremely successful in whatever he decides to do. He’s been serving as an assistant coach, running backs coach. He’s been very involved. He’s been traveling to all the games and all those types of things.”

Brown led the Nittany Lions in rushing last year with 890 yards, a 6.9-yard average, and 12 touchdowns. He rolled up 593 yards on the ground in his last five games, including a program bowl-record 202-yard performance in the team’s Cotton Bowl win over Memphis.

Brown’s late burst was remembered in the preseason. The 5-foot-11, 217-pound Brown was named to the watch lists for the Maxwell Award, the Paul Hornung Award, and the Doak Walker Award, and he was named preseason All-Big Ten by two publications.

“It’s heartbreaking,” Franklin said. “When we found out about it, you’re in shock. You feel physically sick about it. So you hurt for the kid. Obviously, it’s magnified because of all the conversations that were going on nationally about Journey and what he was going to be able to do this season. But I’ll tell you, the kid has been phenomenal. He’s handled it better than, I think, anybody I’ve ever been around.”

Brown, who ran a time of 10.43 seconds in 2017 for Meadville High School to break the PIAA Class AA record held by former Penn Wood star and Olympian Leroy Burrell in the 100 meters, sat out his first season at Penn State and carried the ball only eight times as a redshirt freshman before blossoming last year.

“After all the waiting and watching, I finally had the opportunity to showcase what I was born to do, and hopefully set myself up to achieve my lifelong dream of playing in the NFL,” Brown said in his Twitter statement. "Unfortunately, the dream will never be realized.

“The pain of not being able to play the game I love any more hurts and I can’t explain how I am feeling right now. However, I can walk away from the game knowing I truly gave my all at every practice, on every down and in the locker room every day. You never know when you will play your last snap, but I know I left it all out there and have no regrets.”

Franklin often has expressed his admiration for how Brown handled adversity in his life. Since enrolling at Penn State in 2017, Brown has lost his grandmother, two aunts, an uncle, two cousins, and a close friend. When Brown was first diagnosed with his heart condition, Franklin felt he would “stay positive and focus on the blessing.”

On Wednesday, Franklin’s voice cracked when he called Brown “a special kid.” He expressed confidence about his future.

“He’s going to be very successful,” Franklin said. “I don’t know if he wants to stay in football or whatever he decides to do, but he’s going to be unbelievably successful. I know our team is going to continue to support him and rally around him.”

Penn State star RB Journey Brown forced to retire from football due to heart condition

Brown's condition was discovered through covid-19 testing, though it's unrelated to the virus.

Penn State running back Journey Brown announced Wednesday that his playing career is over after he was diagnosed with a heart condition that will force him to "medically retire from the game of football." Brown, a redshirt junior, had not played for the Nittany Lions yet this season to due the issue, which he revealed to be hypertrophic cardiomyopathy. Penn State coach James Franklin said the condition was discovered in September through a routine COVID-19 test but was not related to the coronavirus.

A former three-star prospect, Brown did not play during his redshirt season in 2017 and saw limited action in 2018 before emerging as the team's leading rusher last season with 890 yards and 12 touchdowns on 6.9 yards per carry.

"I can still remember the first time I truly fell in love with the game I've been playing since 4th grade," Brown wrote in his announcement. "Back then it was a game I played for fun, but when I was a sophomore in high school, my life changed, and I fell in love with football, all I could think of was when can I play, how can I get better, what can I do to be a better teammate, and at that moment, football became less of a game for me and more of a lifestyle. That lifestyle put me in position to be blessed to have a chance to play football at Penn State. My first year here was rough at times, but when you love the game of football as much as I do, you put your head down and work through scout team, lion's den and the waiting and watching. I finally had the opportunity to showcase what I was born to do and, hopefully, set myself up to achieve my life-long dream of playing in the NFL. Unfortunately, the dream will never be realized."

Although Brown's playing career is over, coaching could be in his future. Franklin said Wednesday that Brown has been serving as an assistant running backs coach while traveling with the Nittany Lions this season.

"Journey is one of the most popular and respected players on our team," Franklin said. "The entire organization is rallying behind Journey and his family. We need Nittany Nation to do the same as I know we will. Journey has handled this unbelievably well, and I know he'll be extremely successful in whatever he decides to do.

Penn State's Journey Brown retiring from football due to heart condition

• ESPN staff writer
• Joined ESPN in 2011
• Graduated from Central Michigan

Penn State running back Journey Brown is medically retiring from football after being diagnosed with hypertrophic cardiomyopathy.

Head coach James Franklin announced Wednesday night that the redshirt junior would no longer be able to play. Brown had been held out of the season, as Penn State announced in October that a medical condition was discovered in the offseason.

According to WebMD, hypertrophic cardiomyopathy "is associated with thickening of the heart muscle ... which leads to stiffening of the walls of the heart and abnormal aortic and mitral heart valve function, both of which may impede normal blood flow out of the heart."

"It was discovered through a routine COVID-19 test, although it is not COVID-related," Franklin said. "We learned about this in early September, and we've been working through this and dealing with this as a team. Journey is one of the most popular and respected players on our team.

"The entire organization has rallied behind Journey and his family."

Brown started 10 games for Penn State last season and led the team with 890 yards and 12 touchdowns. The 5-foot-11, 217-pound back was set to be one of the more important players coming back on offense.

Brown took to social media Wednesday night to express his feelings about the diagnosis.

I didn't even expect to make it this far but it's about Journey, not the destination. #HLM #SIAM pic.twitter.com/nbQrIsjXzY — SUNNY-D☀️🦕 (@JourneyBrown6) November 11, 2020

He wrote about the first time he fell in love with football and how it changed his life and how it became less of a game and more of a lifestyle.

"I finally had the opportunity to showcase what I was born to do and, hopefully, set myself up to achieve my lifelong dream of playing in the NFL," Brown wrote. "Unfortunately, the dream will never be realized as I have been diagnosed with hypertrophic cardiomyopathy, which will force me to medically retire from the game of football. The pain of not being able to play the game I love anymore hurts and I can't explain how I am feeling right now."

Brown went on to say that he gave everything he had and has no regrets about how his journey is ending.

Penn State has been without Brown this season and lost running back Noah Cain to injury. Devyn Ford is now carrying the workload in the run game, along with quarterback Sean Clifford . The team has 388 total rushing yards and two touchdowns.

Study finds iron-rich enamel protects, but doesn’t color, rodents’ orange-brown incisors

FOR IMMEDIATE RELEASE

“Ingenious Architecture and Coloration Generation in Enamel of Rodent Teeth” ACS Nano

Chattering squirrels, charming coypus, and tail-slapping beavers — along with some other rodents — have orange-brown front teeth. Researchers have published high-resolution images of rodent incisors in ACS Nano , providing an atomic-level view of the teeth’s ingenious enamel and its coating. They discovered tiny pockets of iron-rich materials in the enamel that form a protective shield for the teeth but, importantly, don’t contribute to the orange-brown hue — new insights that could improve human dentistry.

Human and animal teeth are coated in a complex crystalline substance called enamel. And while enamel is the hardest tissue in our bodies, it’s even harder in rodents. Their ever-growing incisors have an additional outer layer of acid-resistant, iron-rich enamel. Previously, researchers suggested that this iron-rich material was also responsible for the striking orange to brown color of many rodents’ incisors. However, the microscopic structure of the iron-rich enamel hadn’t been fully characterized. To learn more about the composition of rodent tooth enamel, Vesna Srot and colleagues captured high-resolution images of incisor specimens from several species.

The researchers collected incisors from rodents that live in different environments: beavers, coypus, squirrels, marmots, rats, voles and mice. To investigate the structure, elemental composition and color transmission of the enamel, thin slices were taken from different sections of the teeth and prepared for imaging with optical microscopy, 3D focused ion beam tomography and scanning transmission electron microscopy. The micro- and nano-scale resolution images revealed:

• Initially, cells that synthesize enamel components produce 6- to 8-nanometer-wide particles of iron-storage proteins called ferritins, which are the source material for iron ions in matured enamel.
• As enamel matures and solidifies before the teeth erupt from the gums, iron-containing ferrihydrite-like material moves into the outer layer of enamel, occupying empty spaces between calcium-containing hydroxyapatite crystals.
• The microstructure of the iron-rich enamel contains elongated nanometer-sized pockets filled with small amounts of the ferrihydrite-like material, which contribute acid resistance even though the filled pockets account for less than 2% of the volume of iron-rich enamel.  
• While these results suggest that different types of rodents develop the iron-rich outer enamel layer in a similar way, the depth of the layer vary by species, with mice having the thinnest and coypus having the thickest layers.
• Finally, the intense orange-brown color of rodent incisors doesn’t come from the filled pockets in the enamel, as was previously thought, but from a thin surface layer composed of aromatic amino acids and inorganic minerals.

The researchers suggest that adding small amounts of ferrihydrite-like or other colorless biocompatible iron minerals to dental care products could provide exceptional protection for human tooth enamel. In addition, incorporating small amounts of iron hydroxides into synthetic enamel could produce longer-lasting restorations for human teeth.
