Look carefully! Mathematicians have invented a new 13-sided shape that can be tiled infinitely without ever repeating a pattern. They call it “the einstein.”

For decades, mathematicians wondered if it was possible to find a single special shape that could perfectly tile a surface, without leaving any gaps or causing any overlaps, with the pattern never repeating. Of course, this is trivial to do with a pattern that repeats — just look at a bathroom or kitchen floor, which is probably made up of simple rectangular tiles. If you were to pick up your floor and move it (called a “translation” in mathematics), you could find a position where the floor looks exactly the same as before, proving that it’s a repeating pattern.

In 1961, mathematician Hao Wang conjectured that aperiodic tilings, or tilings that never become a repeating pattern, were impossible. But his own student, Robert Berger, outwitted him, finding a set of 20,426 shapes that, when carefully arranged, never repeated. He then slimmed that down to a set of 104 tiles. That means that if you were to buy a set of those tiles, you could arrange them on your kitchen floor and never find a repeating pattern.

In the 1970s, Nobel prize-winning physicist Roger Penrose found a set of only two tiles that could be arranged together in a nonrepeating pattern, now known as a Penrose tiling.

Since then, mathematicians around the world have searched for the aperiodic tiling holy grail, called “the einstein.” The word doesn’t come from the famous Albert but from the German translation of his last name: one stone. Could a single tile — one “stone” — fill a two-dimensional space without ever repeating the pattern it creates?

The answer was just discovered by David Smith, a retired printing technician from East Yorkshire, England. How did he come across this remarkable solution? “I’m always messing about and experimenting with shapes,” Smith told The New York Times (opens in new tab) . “It’s always nice to get hands-on. It can be quite meditative.”

Smith and his co-authors dubbed the new shape “the hat,” mostly because it vaguely resembles a fedora. Although mathematicians have known about the shape, which has 13 sides, they had never considered it a candidate for aperiodic tiling.

“In a certain sense, it has been sitting there all this time, waiting for somebody to find it,” Marjorie Senechal (opens in new tab) , a mathematician at Smith College who was not part of the study, told The Times.Related stories—Mathematicians make rare breakthrough on notoriously tricky ‘Ramsey problem’

—Two mathematicians just solved a decades-old math riddle — and possibly the meaning of life

Smith worked closely with two computer scientists and another mathematician to develop two proofs showing that “the hat” is an aperiodic monotile — an einstein. One proof relied on building larger and larger hierarchical sets of the tiles, showing how the pattern never repeats as the surface area grows. The other proof relied on the team’s discovery that there wasn’t just one of these tiles, but an infinite set of related shapes that could all do the trick. The team’s paper is available on the preprint server arXiv (opens in new tab) but has not yet been peer-reviewed, and the proofs have not yet been scrutinized.

These kinds of aperiodic tilings are more than mathematical curiosities. For one, they serve as a springboard for works of art, like the Penrose tiling found at the Salesforce Transit Center (opens in new tab) in San Francisco, and reveal that some medieval Islamic mosaics employed similar nonrepeating patterns.

Aperiodic tilings also help physicists and chemists understand the structure and behavior of quasicrystals, structures in which the atoms are ordered but do not have a repeating pattern.

SEC showdowns! The Jeweled Shillelagh! Toss-ups everywhere! Week 8 is loaded!

How do you take a typical big October Saturday and make it even better? By making every big game a toss-up.

Week 8 of the college football season gives us four ranked-versus-ranked battles — an enormous SEC tripleheader and Notre Dame-USC. My SP+ ratings project all four games to finish within 3.1 points. Then, there’s the Holy War (BYU-Utah), too. All in all, there are 60 FBS games this weekend, and 32 are projected within one score. We should get at least a couple of classics among the big games, and the thing that separates college football Saturdays from anything else — sheer depth of action — should be on overwhelming display.

There are stakes, too! The SEC race is a giant, puddly mess and should achieve only so much clarity Saturday. Notre Dame-USC could be a College Football Playoff eliminator of sorts (and, oh yeah, it might be the last Notre Dame-USC game for a while). The Big 12 and ACC each have a couple of huge, title-related games, and we’ve got hierarchy-establishing battles in the Sun Belt and Mountain West.

It’s a lot! Let’s make some sense of it! Here’s everything you need to follow in a blood pressure-unfriendly Week 8.

All times are ET and are on Saturday unless otherwise noted.

The SEC tripleheader of Greg Sankey’s dreams

The SEC has no team in the current SP+ top four, but it has eight of the next nine and 10 of the top 19. The conference title race and the race for playoff spots are up for grabs, especially if Alabama stops producing loads of close-game magic.

On Saturday, the league gets the tripleheader of its dreams: Three ranked-versus-ranked battles, all relative toss-ups. The results could establish a bit of a hierarchy within the conference, or they could make things even messier. (As always, I root for the latter.)

No. 5 Ole Miss at No. 9 Georgia (3:30 p.m., ABC)

Last year, Georgia muscled its way to the SEC title, boasting less upside than we’re used to seeing but grinding out victories. But the Dawgs’ high floor was no match for Ole Miss’ high ceiling: The Rebels dominated the line of scrimmage and posted a shockingly easy 28-10 win; it was Georgia’s worst loss since 2019.

1:20

Highlight: No. 16 Rebels keep playoff hopes alive with win vs. No. 3 Georgia

Ole Miss wins the turnover battle, highlighted by stripping the ball from the Bulldogs in the final minutes to solidify a 28-10 win and stay relevant for the College Football Playoff.

If Georgia starts slowly again, Ole Miss might lay down the hammer again. UGA trailed Auburn by 10 points in the first quarter, Alabama by 14 in the second and Tennessee by 14 in the first. That Gunner Stockton and the Dawgs fought back to win two of those three is another reminder that Kirby Smart teams will always be tough as hell. But they lost to Bama, and they might not be able to afford more than one additional defeat. At some point, they have to play well.

Ole Miss messed around last week, stumbling through early miscues and needing a late stop to beat Washington State 24-21. Maybe the Rebels were looking ahead to UGA? This is a pretty big game, and not only because the Rebels haven’t won in Athens since 1996. They’re one of only two remaining unbeatens in the parity-soaked SEC, and a win here would put them in excellent position to reach their first SEC championship game.

Georgia holds the advantages on the ground, while Ole Miss controls the air.

When Georgia has the ball
Yards per carry (not inc. sacks): Georgia offense 79th, Ole Miss defense 106th
Yards per dropback: Ole Miss defense 36th, Georgia offense 59th

When Ole Miss has the ball
Yards per carry: Georgia defense sixth, Ole Miss offense 63rd
Yards per dropback: Ole Miss offense fifth, Georgia defense 64th

Georgia should exploit Ole Miss’ shoddy run defense, but the Rebels could counter that with a big passing advantage. Trinidad Chambliss distributes the ball well to five or six receivers, and even after playing against Auburn’s destitute passing game, Georgia still ranks 117th in sack rate. Chambliss will likely have time to find open guys.

Current line: UGA -7.5 | SP+ projection: UGA by 1.8 | FPI projection: UGA by 5.3

No. 11 Tennessee at No. 6 Alabama (7:30 p.m., ABC)

One of my go-to measures is postgame win expectancy. It takes a look at the predictive stats a game produces — the stuff that feeds into SP+ — and says, “With these stats, Team A would have won this game X% of the time.” It’s a good way of measuring if a team is winning in a sustainable way or if good fortune is involved.

In wins over both Georgia and Missouri, Alabama’s postgame win expectancy was under 30%. The Crimson Tide handily lost the explosiveness battle against UGA and was both less efficient and less explosive than Mizzou, but won both games with the right combination of clutch-play success. That’s tough to sustain over a long season, though Kalen DeBoer’s 2023 Washington team did just that while reaching the national title game. If you have the right quarterback play and close-game execution, you can pull one over on the stat gods for a little while. The stat gods always get their comeuppance — as in 2024, when DeBoer’s Bama looked like an 11-win team on paper but went 9-4 — but you can ride it out for a bit.

The close games probably aren’t going to stop. Of Bama’s next six games, five are projected within 8.1 points. The Tide will require a lot more of what we saw against Missouri, when Ty Simpson didn’t produce dazzling stats (23 completions for 200 yards with four sacks) but completed some brilliant passes on third- and fourth-and-long.

Alabama Crimson Tide vs. Missouri Tigers: Full Highlights

Alabama Crimson Tide vs. Missouri Tigers: Full Highlights

Simpson has gotten help from running back Jam Miller of late, though he is questionable for Saturday (concussion protocol). The defense got carved up on a couple of drives but controlled Mizzou for a large run in the middle of the game.

Tennessee is in pretty good shape, playoff-wise; the 5-1 Vols are projected favorites in each game after this. But their defense, so excellent last year, ranks just 78th in points allowed per drive. Luckily for the Vols, they’re 12th on offense. They are efficient via run and pass, and RB DeSean Bishop and WRs Chris Brazzell II and Mike Matthews are big-play machines. But if Simpson made key passes against Georgia’s and Mizzou’s defenses, it’s pretty hard to see Tennessee stopping the Tide when it counts.

Current line: Bama -7.5 | SP+ projection: Bama by 2.2 | FPI projection: Bama by 6.1

No. 10 LSU at No. 17 Vanderbilt (noon, ABC)

LSU’s defense, problematic for years, has allowed more than 10 points just once, combining great pass coverage with great ball pursuit and allowing the 5-1 Tigers to mostly overcome their worst offense of the Brian Kelly era. Vandy, meanwhile, won its first five games by an average of 32 points before red zone turnovers spoiled an upset bid against Bama. The Commodores’ defense is unexceptional, but the offense ranks second nationally in success rate. Quarterback Diego Pavia keeps the offense moving (and grinds out some hard rushing yards), while running backs Sedrick Alexander and Makhilyn Young are averaging 7.5 yards per carry.

Close games will determine the SEC’s CFP bids; five of Vandy’s last six games are projected within 6.5 points, per SP+, and four of LSU’s last six are within 4.5. The loser of this one will likely have spent its final mulligan and will have to win a lot of coin-flip games to stay in the hunt.

Current line: Vandy -2.5 | SP+ projection: Vandy by 0.4 | FPI projection: Vandy by 2.7


For the Jeweled Shillelagh (and playoff hopes)

No. 20 USC at No. 13 Notre Dame (7:30 p.m., NBC)

I’m struggling to get past the idea that we might lose Notre Dame-USC, at least for a little while, for embarrassingly silly reasons. Just in case sanity doesn’t prevail, we deserve a barn burner Saturday night.

In a rivalry based on long-term momentum swings, Notre Dame has held the advantage for most of the past 15 years, but this one appears relatively even on paper. Since losing its first two games by a combined four points — both to current top-five teams (Miami and Texas A&M) — Notre Dame has won four games by an average of 30. The defense had big-play issues early on but has allowed 27 total points in the past three weeks and should keep improving now that corner Leonard Moore is healthy again.

Quarterback CJ Carr has been absolutely dynamite. Despite being a redshirt freshman, and despite substandard performance from the offensive line — which has allowed quite a few negative run plays and merely average pressure numbers — he’s 11th in Total QBR. On third-and-7 or more, Notre Dame ranks second nationally with a 44% conversion rate. Carr’s ceiling is spectacularly high.

Of course, USC’s Jayden Maiava ranks first in Total QBR. He’s completing 72% of his passes at 15.1 yards per completion. That’s quite the high-end combination.

Maiava has done plenty of damage against bad defenses, but the Trojans topped 30 points against Illinois and Michigan, too. It helps to have a run game you can lean on, and USC’s might be the most underrated in the country. Backs Waymond Jordan, Eli Sanders and King Miller have combined to average 191.7 yards per game and 7.0 per carry. Jordan and Sanders got hurt against Michigan — they’re both likely out Saturday — so Miller, a walk-on redshirt freshman, went for 158 yards. That says great things about the O-line, especially considering it has been battling some injuries.

That leaves the USC defense. A consistent liability in Lincoln Riley’s nine years as a head coach, the Trojans have been mostly solid this year, but they got beat for some long passes against Michigan State and Illinois. That will probably happen Saturday, too, but if they can hold the Irish to 31 points or so, Maiava & Co. could top that.

Current line: Irish -9.5 (up from -7.5 on Sunday) | SP+ projection: Irish by 3.1 | FPI projection: Irish by 5.1


This week in the Big 12

There’s nothing I enjoy more than a nice, silly Big 12 title race, and Texas Tech’s current dominance levels suggest at least half of the Big 12 championship game matchup is as good as settled. That could change, obviously, but when you lose your quarterback to injury twice in three games and extend your lead by 20-plus points in both games, you’re proving something. We’ll see if the Red Raiders can keep proving something against the defending conference champs.

Regardless of Tech’s dominance, there are two spots available in Jerry World, and the fight for the other spot (at least) is up for grabs. The winner of Saturday night’s Holy War in Provo, Utah, will become the favorite to land that one.

No. 7 Texas Tech at Arizona State (4 p.m., Fox)

Arizona State was hit-and-miss early last season, then lost a game with quarterback Sam Leavitt injured. That summarizes this season as well. Leavitt should return after missing last week’s loss to Utah, and if the Sun Devils hit the gas like last year, everything’s still on the table.

Last week was pretty demoralizing, though. Leavitt’s presence wouldn’t have done much to stop Utah from scoring touchdowns on six of seven possessions. The Sun Devils rank 71st in points per drive and 94th in points allowed; they simply might not have enough to offer.

A few weeks ago, Texas Tech pushed around Utah just like the Utes did to ASU. Even if quarterback Behren Morton (questionable) can’t go, Will Hammond has played well — he isn’t as consistent a passer, but he offers far more with his legs. And either way, ASU still has to score on a defense ranked fifth in points allowed per drive and featuring two of the best defenders in college football (linebacker Jacob Rodriguez and edge rusher David Bailey).

Current line: Tech -7.5 (down from -10.5) | SP+ projection: Tech by 15.5 | FPI projection: Tech by 7.3

No. 23 Utah at No. 15 BYU (8 p.m., Fox)

Utah has responded as well as possible to the blowout loss to Tech. Outmuscled at the line of scrimmage by the Red Raiders, the Utes have done all the pushing since, walloping West Virginia and Arizona State by a combined 90-24. They aren’t creating many big plays — an issue for years — but quarterback Devon Dampier & Co. are second in rushing success rate and eighth in passing success rate. BYU’s defense also is pretty efficient, though the Cougars have allowed an increasing point total in every game this season. At some point, that becomes an obvious problem, but this is the second-best defense Utah has faced.

Of course, Utah’s defense is by far the best Bear Bachmeier has faced. The unbeaten BYU freshman quarterback came through with his legs in last week’s comeback win over Arizona, but he also went 12-for-29 passing with two interceptions. Utah’s defense is awesome at the front (where end John Henry Daley is a breakout star) and back (where the Utes rank sixth in completion rate allowed).

Current line: Utah -3.5 | SP+ projection: Utah by 0.5 | FPI projection: BYU by 0.3


The ACC title race takes shape, too

As with Texas Tech in the Big 12, Miami’s fast start has established a clear front-runner in the ACC title race. But two teams will make the ACC championship game, and five are unbeaten early in ACC play (Miami, Georgia Tech, Duke, Virginia and SMU). They’re among six teams, along with Louisville, who have at least a 7% chance at the conference title, per SP+.

Conveniently, four of those six teams are playing head-to-head this weekend.

Louisville at No. 2 Miami (Friday, 7 p.m., ESPN)

Louisville is 4-1 and a projected favorite in six of its last seven games. The Cardinals appear likely to post at least nine wins for the third straight time under Jeff Brohm. The defense has been excellent, and running back Isaac Brown remains one of the most explosive in college football.

The Cardinals still feel pretty disappointing this season, though, at least on offense. Brown and Duke Watson have been slowed because of injuries, and quarterback Miller Moss struggled on several dropbacks in their loss to Virginia. The offensive line is allowing loads of negative plays. All’s forgiven if they win Friday night, but they’ll have to raise their game.

This is about where things went awry for a fast-starting Miami team in 2024, but with Rueben Bain Jr. and Mohamed Toure anchoring a far more stable defense and the offensive line living up to hype, the Hurricanes don’t seem interested in allowing that to happen again. Granted, the offense hasn’t been quite as effective as it has gotten credit for, mainly due to a lack of explosiveness — they’re 13th in success rate but just 126th in yards per successful play. Carson Beck hasn’t been amazing on third downs either, and if Louisville can knock the Hurricanes off schedule, the Cardinals’ dynamite pass rush could impact the game. But Louisville will still need to steer out of the mud and start scoring points.

Current line: Miami -13.5 | SP+ projection: Miami by 7.9 | FPI projection: Miami by 12.4

No. 12 Georgia Tech at Duke (noon, ESPN)

In Duke’s first big home game of 2025, the Blue Devils suffered five turnovers against Illinois in a 45-19 loss. They won a majority of the game’s plays but were on the wrong end of all the catastrophes. (They seemed to let that loss beat them the next week, too, falling behind 24-3 to Tulane before losing by seven.)

Now comes another big home game. The Blue Devils have won their first three conference games by an average of 43-19, and Darian Mensah, responsible for three of those five Illinois turnovers, has been increasingly dominant.

Georgia Tech has drifted a bit in the other direction. The Yellow Jackets remain unbeaten, but after early wins over Colorado and Clemson, they’ve underachieved against SP+ projections for three straight games. They can still run the heck out of the ball with QB Haynes King and RBs Jamal Haynes and Malachi Hosley, but they are struggling to knock opponents off schedule and rush the passer. Duke can defend the run and stay on schedule beautifully.

Current line: Duke -1.5 | SP+ projection: Tech by 0.3 | FPI projection: Duke by 2.9


A pair of elimination games (of sorts) in the Group of 5

Per the Allstate Playoff Predictor, five Group of 5 teams have at least a 5% chance of reaching the CFP: Memphis (43%), USF (30%), Tulane (11%), UNLV (8%) and Boise State (6%). Memphis and USF have easier games that were relegated to the Playlist below, but BSU and UNLV face off, and a maddening Tulane takes on an Army team capable of just about anything.

UNLV at Boise State (3:30 p.m., FS1)

Since the start of 2023, UNLV is 26-8 — 0-3 against Boise State and 26-5 against everyone else. Is this the year the Rebels finally clear the Boise hurdle?

BSU’s four wins and two losses have come by an average of 24 points. Either it has all worked or it all hasn’t — that’s how things go when your offense is inefficient but explosive and you make sure your opponents are the same. The Broncos make every game a big-play contest.

UNLV is all-or-nothing in a different way: all offense, no defense. The Rebels are averaging more than 38 points per game but allowing nearly 30. They seek turnovers to an almost self-destructive degree and give up 6.3 yards per play. But with quarterback Anthony Colandrea, running back Jai’Den Thomas and receiver Jaden Bradley, they can keep up with anyone in a big-play contest.

Current line: BSU -12.5 (up from -10.5) | SP+ projection: BSU by 7.0 | FPI projection: BSU by 5.7

Army at Tulane (noon, ESPNU)

“We’re a really sloppy football team that finds ways to win games. And I’m going to lose my mind because we’re so immature. We’ve got to grow up fast.” That’s what Tulane’s Jon Sumrall said after last week’s narrow 26-19 win over East Carolina, and, well, that about summed it up. The Green Wave boast major upside and two power-conference wins, they’ve been inconsistent and have slipped to 64th in SP+. But they’re still 5-1! If they shift into gear, they could easily be in the CFP.

Army lost to Tarleton State and got blown out by ECU but also beat Kansas State and won its past two games by 35 combined points. The Black Knights can’t even slightly pass, but they don’t lose yards and the defense prevents big plays. Can Tulane summon maturity and move to 6-1?

Current line: Tulane -9.5 | SP+ projection: Tulane by 7.8 | FPI projection: Tulane by 11.2


Week 8 chaos superfecta

We’re once again using this space to will chaos into existence, looking at four carefully curated games with pretty big point spreads and mashing them together into a much more upset-friendly number. And we’re in a funk! The sport has had plenty of chaos, but the superfecta’s gone 0-3 since a 3-1 start.

It’s time to rectify that by taking down a Big Ten favorite. SP+ says there’s only a 32% chance that Maryland (72% win probability over UCLA), Nebraska (74% over Minnesota), Oregon (85% over Rutgers) and Indiana (95% over Michigan State) all win. It’s rally time!


Week 8 playlist

Here are some more games you should pay attention to if you want to get the absolute most out of the weekend, from both information and entertainment perspectives. (Don’t worry, I’m not trying to convince you to watch Iowa-Penn State. Our relationship means too much to me to do that to you.)

Friday evening

No. 25 Nebraska at Minnesota (8 p.m., Fox). Two fun, young QBs — Nebraska’s Dylan Raiola and Minnesota’s Drake Lindsey — have, with help from top-30 defenses, led their teams to a combined 9-3 record, but Nebraska is looking for more. The Huskers have a 30% chance at a 10-2 finish or better, per SP+; that would be their first such season in ages and would theoretically insert them into the playoff race.

Current line: Nebraska -8.5 (up from -6.5) | SP+ projection: Nebraska by 10.2 | FPI projection: Nebraska by 7.2

North Carolina at California (10:30 p.m., ESPN). North Carolina got a bye week to read all those “How it’s all gone wrong for Bill Belichick” stories. This is one of only two remaining games in which they’re not projected as a double-digit underdog. If they can’t get past Jaron-Keawe Sagapolutele and Cal — also coming off a bye week — they might not get past anyone.

Current line: Cal -10.5 | SP+ projection: Cal by 8.7 | FPI projection: Cal by 7.5

Early Saturday

No. 14 Oklahoma at South Carolina (12:45 p.m., SECN). OU rushed John Mateer back to action, but he was rusty and overwhelmed against Texas. South Carolina’s defense has stabilized significantly and could offer resistance, but at some point, the Gamecocks’ offense, currently 123rd in points per drive, needs to show up. Quarterback LaNorris Sellers isn’t getting much help, but he’s not helping himself enough, either.

Current line: OU -5.5 | SP+ projection: OU by 8.8 | FPI projection: OU by 1.1

Washington at Michigan (noon, Fox). I’m still confused by the lack of pollster love for 5-1 Washington. The unranked Huskies got far fewer AP votes than either two-loss Illinois or two-loss Michigan, but they can theoretically rectify that with a win in Ann Arbor. The Wolverines’ offense has no-showed in both losses, but Washington games can turn into track meets pretty easily.

Current line: Michigan -6.5 | SP+ projection: Michigan by 2.4 | FPI projection: Michigan by 4.5

Baylor at TCU (noon, ESPN2). The Revivalry is a Last Chance Saloon situation for a TCU team just 1-2 in Big 12 play. It’s probably noteworthy that BU’s Sawyer Robertson and TCU’s Josh Hoover will be passing against defenses that rank 103rd and 101st, respectively, in yards allowed per dropback. This game better have at least 70 combined points. (It did last year.)

Current line: TCU -2.5 | SP+ projection: TCU by 7.8 | FPI projection: TCU by 3.2

Saturday afternoon

No. 4 Texas A&M at Arkansas (3:30 p.m., ESPN). Texas A&M has mastered the art of simply sitting on games, leaning heavily on a dynamite offensive line and pass rush and waiting for opponents to fall over. Arkansas just lights every game on fire; the Razorbacks have scored at least 31 points in five games and allowed at least 32 in four straight. They’ve almost beaten three ranked teams now — they’re dangerous, if self-destructive, underdogs.

Current line: A&M -7.5 | SP+ projection: A&M by 9.0 | FPI projection: A&M by 5.4

SMU at Clemson (3:30 p.m., ACCN). After terribly disappointing September campaigns, both Clemson and SMU — last year’s ACC championship game competitors — have stabilized with a pair of comfortable ACC wins. Clemson has been a bit more demonstrative, but the Tigers, at 2-2 in the ACC, are playing from behind; with a slight upset, SMU would be 3-0 in ACC play and back in the title conversation.

Current line: Clemson -9.5 | SP+ projection: Clemson by 4.4 | FPI projection: Clemson by 3.3

Mississippi State at Florida (4:15 p.m., SECN). Mississippi State got a bye week after its disappointing performance against Texas A&M. Florida acquitted itself slightly better against the Aggies last Saturday, but after that ultra-physical affair, the Gators will have to deal with the ultra-fast MSU attack. Can they get receiver Dallas Wilson, the hero of the Texas game, going again?

Current line: Florida -9.5 | SP+ projection: Florida by 2.6 | FPI projection: Florida by 4.4

Old Dominion at James Madison (3:30 p.m., ESPNU). This one was looking like it might be the G5 game of the week, but JMU’s offense underachieved for a second straight game in a narrower-than-expected win over Louisiana, and ODU self-destructed with five turnovers and three turnovers on downs in a huge loss to Marshall. This is still huge for Sun Belt East title purposes, at least.

Current line: JMU -1.5 | SP+ projection: JMU by 5.4 | FPI projection: ODU by 0.8

No. 22 Memphis at UAB (4 p.m., ESPN2). Granted, there could be some UCLA-style, nothing-to-lose vibes from a UAB team that just fired coach Trent Dilfer. But that’s the only reason to think this one will be close. Memphis is running the ball brilliantly, and the Tigers’ defense is playing its best ball in more than a decade.

Current line: Memphis -22.5 | SP+ projection: Memphis by 27.0 | FPI projection: Memphis by 25.7

Michigan State at No. 3 Indiana (3:30 p.m., Peacock). Granted, UCLA went from winless and hopeless to genuinely exciting overnight, so anything’s possible, but the team UCLA smoked last week — Michigan State — is also looking awfully hopeless. The most interesting thing about this one might be how Indiana responds to its greatest week of news clippings ever. Can the Hoosiers remain focused?

Current line: IU -27.5 | SP+ projection: IU by 26.4 | FPI projection: IU 26.9

UTSA at North Texas (3:30 p.m., ESPN+). North Texas let a huge opportunity slip through its fingers last week thanks to a 3½-minute, 28-0 run by USF in a 63-36 loss to the Bulls. Can the Mean Green avoid a hangover and remain in the American Conference race by taking care of an all-or-nothing UTSA and its all-or-nothing run game (Robert Henry Jr. and Will Henderson III: 1,004 yards at 7.3 per carry)?

Current line: UNT -3.5 (down from -5.5) | SP+ projection: UNT by 4.3 | FPI projection: UNT by 2.0

No. 1 Ohio State at Wisconsin (3:30 p.m., CBS). I can’t believe Wisconsin is making Luke Fickell coach this game before firing him.

Current line: OSU -25.5 | SP+ projection: OSU by 25.4 | FPI projection: OSU by 23.4

Saturday evening

No. 16 Missouri at Auburn (7:45 p.m., SECN). Missouri had a golden opportunity to beat Alabama but couldn’t get the job done. If the Tigers rebound well, the CFP is still in play, but they can’t fall victim to Auburn’s nonsense. Hugh Freeze’s Tigers defended well enough to play Oklahoma, Texas A&M and Georgia achingly close but didn’t have the offense to seal the deal. Will they ever?

Current line: Mizzou -1.5 (flipped from Auburn -2.5) | SP+ projection: Mizzou by 5.5 | FPI projection: Mizzou by 0.7

No. 6 Oregon at Rutgers (6:30 p.m., BTN). Rutgers quarterback Athan Kaliakmanis is on pace for 3,500 passing yards, and the Scarlet Knights have scored at least 28 points in five of six games. This is an offense capable of leading an upset, but the RU defense is just about Greg Schiano’s worst ever. Think that might hinder them against Dante Moore and the ridiculously efficient Oregon offense?

Current line: Oregon -17.5 (up from -14.5) | SP+ projection: Oregon by 16.5 | FPI projection: Oregon by 11.6

No. 21 Texas at Kentucky (7 p.m., ESPN). Kentucky might be a lost cause at this point — per SP+, the Wildcats’ odds of losing out (4%) aren’t that much lower than their odds of bowling (11%). But they defend the run pretty well and pressure quarterbacks. Either Arch Manning makes good plays against a bad secondary, or Kentucky gets enough stops to make this interesting.

Current line: Texas -12.5 | SP+ projection: Texas by 14.8 | FPI projection: Texas by 10.6

Washington State at No. 18 Virginia (6:30 p.m., The CW). The transfer-driven UVA offense, led by QB Chandler Morris and RB J’Mari Taylor, has scored 30-plus points every week. The Wazzu defense, meanwhile, is confusing: The Cougs have allowed 59 points twice but have allowed 12.5 points per game in their four other games. The Hoos should handle this one, but Wazzu nearly stunned Ole Miss last week.

Current line: UVA -17.5 | SP+ projection: UVA by 13.8 | FPI projection: UVA by 18.9

Florida Atlantic at No. 19 USF (7:30 p.m., ESPNU). This should be the fastest game of the week. In terms of seconds per play, USF ranks first and FAU ranks third. USF is faster, but four FAU games have topped 66 combined points. Even if this is an easy win for the Bulls, it should be pretty prolific.

Current line: USF -21.5 | SP+ projection: USF by 17.4 | FPI projection: USF by 19.6

Late Saturday

Florida State at Stanford (10:30 p.m., ESPN). Florida State’s defense has underachieved for a while now, and the offense has slipped just enough to make that costly. The Noles have lost three games in a row, but while playing at Stanford requires a cross-country trip, it should be a get-right opportunity. The Cardinal’s most likely record right now? 3-9, which was their record the past four seasons.

Current line: FSU -18.5 | SP+ projection: FSU by 19.3 | FPI projection: FSU by 11.1


Smaller-school showcase

Let’s once again save a shout-out for the glorious lower levels of the sport. Here are three games you should track. (Yes, I’m giving you a week off from the WIAC race in Division III, even though No. 4 Wisconsin-La Crosse at No. 14 Wisconsin-Platteville should be pretty fantastic. Actually, watch that one too.)

NAIA: No. 7 Lindsey Wilson at No. 9 Campbellsville (12:30 p.m., YouTube). Led by prolific rusher Davontaye Saunders, LWU holds the No. 1 ranking in NAIA SP+, but the Blue Raiders should face a stiff test in the Battle of Highway 55. Campbellsville is averaging 43 points per game, and quarterback Jett Engle is willing to go for broke, for better (14.3 yards per completion, 14 TDs) or worse (seven INTs).

SP+ projection: LWU by 9.4

FCS: No. 11 North Dakota at No. 12 Southern Illinois (3 p.m., ESPN+). It’s not exactly a playoff eliminator, but it’s close. UND and SIU are 4-2 with losses only to FBS opponents (Kansas State and Purdue, respectively) and FCS heavyweights (Montana and North Dakota State). SIU dual-threat quarterback DJ Williams has five 200-yard passing games and two 100-yard rushing games, and UND’s relentless run game grinds opponents into dust.

SP+ projection: UND by 2.2

Division II: No. 3 West Florida at No. 8 West Alabama (6 p.m., FloCollege). Unbeaten Gulf South rivals face off in Livingston. UWA has topped 50 points in two straight games and doesn’t mind going full-on track meet with big-play receivers Dearrius Nelson and TD Parker. UWF, however, plays a bit more defense: Linebacker Ja’Kobe Clinton and tackle Kevin Roberts have already combined for 20 TFLs.

SP+ projection: UWF by 8.9

Donald Trump responds to idea of tunnel connecting Russia and US

Russia’s investment envoy has said research into the feasibility of a tunnel joining the US and Russia started “six months ago”.

Kirill Dmitriev first posted about the idea on Thursday, suggesting a “Putin-Trump” rail tunnel could connect the two countries under the Bering Strait, which separates Russia‘s vast and sparsely populated Chukotka region from Alaska.

Asked about the idea during a press conference with Ukraine’s President Volodymyr Zelenskyy on Friday, Donald Trump called it “interesting”.

He also asked President Zelenskyy what he made of it, to which Mr Zelenskyy replied: “I’m not happy with this idea.”

This prompted laughter from the US side.

What happened at the Trump-Zelenskyy meeting?

Overnight, Mr Dmitriev posted on X, saying: “We have started the feasibility study of the Russia-Alaska tunnel six months ago.

“Russian Direct Investment Fund with partners financed on a commercial basis the first ever railroad bridge between Russia and China.

“The bridge reduced cargo route by more than 700 kilometres,” he said.

He directed a post on X towards Elon Musk, suggesting the tunnel could be dug by the billionaire’s construction firm, Boring Company.

“The dream of a US-Russia link via the Bering Strait reflects an enduring vision – from the 1904 Siberia-Alaska railway to Russia’s 2007 plan,” Mr Dmitriev wrote.

“RDIF has studied existing proposals, including the US-Canada-Russia-China railroad, and will support the most viable.

“Imagine connecting the US and Russia, the Americas and the Afro-Eurasia with the Putin-Trump Tunnel – a 70-mile link symbolizing unity.”

“Traditional costs are $65B+, but @boringcompany’s tech could reduce it to future together,” he added.

There has been no public response from Elon Musk.

AI headshots are changing the way job seekers are seen and get hired in tough labor market

AI headshots are changing the way job seekers are seen and get hired in tough labor market

AI headshots are becoming popular on LinkedIn and in professional portfolios as job seekers look for affordable profile pictures to give them an edge.

Since first impressions happen almost entirely through a screen, a clean, appealing photo is as important as a strong resume. And in a competitive job market, a good headshot can make a big difference. But professional photography has long been a financial barrier for many job applicants with an average starting cost for a professional headshot in the U.S. that can easily run up to hundreds of dollars.

Now job seekers are using fast and inexpensive AI tools to replace costly studio sessions.

“When I was at Yale, it was $200 for a 15-minute session for students,” said Melanie Fan, head of growth at Plush, an AI-powered online search platform for personalized shopping. “It was really expensive. The process of getting the pictures back, rendering them, looking at which ones I looked the best in, and then sending it back to the photographer for edit.”

This frustration has fueled the explosion of AI headshot tools like InstaHeadshots, PhotoPacksAI, HeadshotPro and Aragon AI, services that promise a professional image in minutes starting at under $50. Users simply upload selfies, pick a background, and receive dozens and no photographer is needed.

“After I changed my LinkedIn photo, the amount of inbound I’ve been getting from companies has skyrocketed,” Fan said. “Three to four times more messages from companies.”

Design company Canva recently launched its own AI headshot feature, with the goal of offering users a quick way to create realistic headshots and still be able to retouch or restyle them.

According to a recent Canva job market research report, 88% of job seekers believe a polished digital presence influences hiring decisions, which is up 45% from the year before. This is in line with the general uptick in use of AI as part of the application and hiring process, with 90% of hiring managers saying they have used AI to help with the hiring process, and 96% of job seekers who used AI in the application process saying they received callbacks.

Danny Wu, Canva’s head of AI products, said the goal wasn’t to replace real photography, but to make high quality imagery attainable to everyone no matter the budget or location. Once a user uploads an image, Canva can use AI for adjusting or changing the background, placing something in a different place, and for styling. “This is just a more accessible way to get professional and unique headshots,” Wu said.

Risks and questions about authenticity among HR recruiters

Anyone with a phone can get a LinkedIn-ready headshot, but the technology’s rapid adoption has created new questions about ethics and trust. Many candidates fear looking fake or deceptive and recruiters are on the lookout for AI-generated portraits that look overly smooth or stylized, saying authenticity matters the most.

“It is perceived as risky to use an AI headshot,” said Sam DeMase, ZipRecruiter career expert. “While recruiters accept them, a bad AI-generated headshot will put off most recruiters,” DeMase said. “A poorly done AI-generated headshot is easily recognized, reads as inauthentic, and can hurt the candidate’s chances of being selected.”

However, recruiters are struggling to tell if a headshot is AI produced, and the technology will only get better. “It’s becoming more and more difficult to tell whether a headshot has been enhanced or generated by AI,” DeMase added.

Chris Bora, founder and principal AI architect of Bora Labs and a former Meta engineer, said he built his own headshot generator, Nova Headshot, after being disappointed by existing options. “Some made me look taller and skinnier,” Bora said. “The other ones, they made me look lighter, so it wasn’t really me,” he said. “You don’t need to spend thousands to look professional anymore. You just need a tool that makes you look like yourself on your best day. With Nova, it takes less than ten minutes,” Bora said.

Amber Collins, an AI headshot user, said she still feels uneasy about it, especially since not every app gets it right. “There are a lot of bad apps out there,” Collins said. “Seven fingers, half a necklace, and the rest of it is gone from your neck. I feel guilty using AI. There’s a stigma. I’d 100% prefer to get actual get headshots done,” Collins said.

But ultimately, she says, the benefits outweighed the risks. “In this economy, you have to be mindful of where you’re going to put your money. I don’t need to have my face out there excessively, but having a couple of really good, solid, professional looking headshots is worth it to me,” Collins said.

Wu said the goal for job applicants seeking a headshot should be to use Canva’s tool to balance realism and creativity without losing their identity.

The tension between tech innovation and accessibility on the one hand, and authenticity on the other, will remain.

A LinkedIn spokesperson told CNBC what while the platform does allow the use of tools, including AI, to enhance or create profile photos, “the photo must reflect your likeness.”

“Profile photos that don’t comply with our user agreement or professional community policies may be removed,” the LinkedIn spokesperson said.

DeMase noted that many job candidates remain hesitant to use an AI headshot. “A headshot is one of the few places you can inject humanity into the job search,” he said.

But with job seekers now able to provide the appearance they had access to the same studio lighting, camera, and editing team as the pros, the trend is unlikely to stop.

A recent survey found that headshot use among job seekers is the highest within the Gen Z and millennial generations. And while recruiters may say they still prefer real photos, AI headshots are becoming harder to spot, and less likely to even be reviewed by humans in the first stages of the application process. A recent study from the HR trade group SHRM found that 66% of human resource professionals are using AI to generate their job descriptions, and 44% are using the technology to review or screen applicant resumes.
