The tempo of a male elephant seal’s call broadcasts his identity to rival males, a new study finds.

Every male elephant seal has a distinct vocalization that sounds something like a sputtering lawnmower — pulses of sound in a pattern and at a pace that stays the same over time.

At a California state park where elephant seals breed each year, researchers played different variations of an alpha male’s threat call to subordinate males who knew him. The seals weren’t as responsive when the tempo of that call was modified substantially, suggesting they didn’t recognize it as a threat. Modifying the call’s timbre — the acoustic quality of the sound — had the same effect, researchers report August 7 in Current Biology. Unlike dolphins and songbirds, elephant seals don’t seem to vary pitch to communicate.
Those vocal name tags serve a purpose. During breeding season, male elephant seals spend three months on land without food or water, competing with rivals for social status and mating rights. Fights between two blubbery car-sized animals can be brutal.

“We’ve seen males lose their noses,” says Caroline Casey, a biologist at the University of California, Santa Cruz. For lower-ranking males, identifying an alpha male by his call and then backing off might prevent a beach brawl.

Neandertals took stick-to-itiveness to a new level. Using just scraps of wood and hot embers, our evolutionary cousins figured out how to make tar, a revolutionary adhesive that they used to make formidable spears, chopping tools and other implements by attaching sharp-edged stones to handles, a new study suggests.

Researchers already knew that tar-coated stones date to at least 200,000 years ago at Neandertal sites in Europe, well before the earliest known evidence of tar production by Homo sapiens, around 70,000 years ago in Africa. Now, archaeologist Paul Kozowyk of Leiden University in the Netherlands and colleagues have re-created the methods that these extinct members of the human genus could have used to produce tar.
Three straightforward techniques could have yielded enough adhesive for Neandertals’ purposes, Kozowyk’s team reports August 31 in Scientific Reports. Previous studies have found that tar lumps found at Neandertal sites derive from birch bark. Neandertal tar makers didn’t need ceramic containers such as kilns and didn’t have to heat the bark to precise temperatures, the scientists conclude.
These findings fuel another burning question about Neandertals: whether they had mastered the art of building and controlling a fire. Some researchers suspect that Neandertals had specialized knowledge of fire control and used it to make adhesives; others contend that Neandertals only exploited the remnants of wildfires. The new study suggests they could have invented low-tech ways to make tar with fires, but it’s not clear whether those fires were intentionally lit.

“This new paper demystifies the prehistoric development of birch-bark tar production, showing that it was not predicated on advanced cognitive or technical skills but on knowledge of familiar, readily available materials,” says archaeologist Daniel Adler of the University of Connecticut in Storrs, who did not participate in the study.
Kozowyk’s group tested each of three tar-making techniques between five and 11 times. The lowest-tech approach consisted of rolling up a piece of birch bark, tying it with wood fiber and covering it in a mound of ashes and embers from a wood fire. Tar formed between bark layers and was scraped off the unrolled surface. The experimenters collected up to about one gram of tar this way.

A second strategy involved igniting a roll of birch bark at one end and placing it in a small pit. In some cases, embers were placed on top of the bark. The researchers either scraped tar off bark layers or collected it as it dripped onto a rock, strip of bark or a piece of bark folded into a cup. The most tar gathered with this method, about 1.8 grams, was in a trial using a birch-bark cup placed beneath a bark roll with its lit side up and covered in embers.

Repeating either the ash-mound or pit-roll techniques once or twice would yield the relatively small quantity of tar found at one Neandertal site in Europe, the researchers say. Between six and 11 repetitions would produce a tar haul equal to that previously unearthed at another European site.

In a third technique, the scientists placed a birch-bark vessel for collecting tar into a small pit. They placed a layer of twigs across the top of the pit and placed pebbles on top, then added a large, loose bark roll covered in a dome-shaped coat of wet soil. A fire was then lit on the earthen structure. This method often failed to produce anything. But after some practice with the technique, one trial resulted in 15.7 grams of tar — enough to make a lump comparable in size to the largest chunks found at Neandertal sites.

An important key to making tar was reaching the right heat level. Temperatures inside bark rolls, vessels, fires and embers varied greatly, but at some point each procedure heated bark rolls to between around 200˚ and 400˚ Celsius, Kozowyk says. In that relatively broad temperature range, tar can be produced from birch bark, he contends.

If they exploited naturally occurring fires, Neandertal tar makers had limited time and probably relied on a simple technique such as ash mounds, Kozowyk proposes. If Neandertals knew how to start and maintain fires, they could have pursued more complex approaches.

Some researchers say that excavations point to sporadic use of fire by Neandertals, probably during warm, humid months when lightning strikes ignited wildfires. But other investigators contend that extinct Homo species, including Neandertals, built campfires (SN: 5/5/12, p. 18).

Whatever the case, Kozowyk says, “Neandertals could have invented tar with only basic knowledge of fire and birch bark.”

An ancient vegetarian dinosaur from the French countryside has given paleontologists something to sink their teeth into.

The most striking feature of a new species of rhabdodontid that lived from 84 million to 72 million years ago is its oversized, scissorslike teeth, paleontologist Pascal Godefroit, of the Royal Belgian Institute of Natural Sciences in Brussels, and his colleagues report October 26 in Scientific Reports. Compared with other dinos of its kind, Matheronodon provincialis’ teeth were at least twice as large but fewer in number. Some teeth reached up to 6 centimeters long, while others grew up to 5 centimeters wide. They looked like a caricature of normal rhabdodontid teeth, Godefroit says.
Of hundreds of fossils unearthed over the last two decades at a site called Velaux-La Bastide Neuve in the French countryside, a handful of jaw bones and teeth now have been linked to this new species, Matheronodon provincialis. The toothy dino belongs to a group of herbivorous, bipedal dinosaurs common in the Cretaceous Period. Rhabdodontids sported bladelike teeth, and likely noshed on the tough woody tissue parts of plants. Palm trees, common in Europe at the time, might have been on the menu.

Rhabdodontid teeth have ridges covered by a thick layer of enamel on one side and little to no ridges or enamel on the other. Teeth in the upper jaw have more ridges and enamel on the outer edge, while the reverse is true for bottom teeth. A closer look at the microstructure of M. provincialis’ teeth revealed an exaggerated version of this — many more ridges and lopsided enamel coating. Enamel typically protects from wear and tear, so chewing would have sharpened the dino’s teeth. “They operated like self-sharpening serrated scissors,” Godefroit says.

Patriots fans always thought that Tom Brady and Jimmy Garoppolo — affectionately known as "Jimmy GQ" — were the closest things to models that they would ever see at the quarterback position. But now, they have an actual model leading their quarterback room.

That would be Mac Jones. No, we're not kidding.
Jones may be better known as key representation for dad bods everywhere at this point in his young career, but in his even younger career, he was actually a child model. He recently spoke about that in an appearance on WEEI 93.7’s "Merloni & Fauria" when he was asked what his "worst job" ever was.

"I used to be a child model/actor, or whatever, and that was fun," Jones said. "There are a few commercials out there you guys could try and find. I think a lot of people know."

To his credit, Jones has been nothing but open about his modeling career. Still, it was news to quite a few people that weren't familiar with his not-so-secret double life. It may be over now, but there are certainly lasting memories from his modeling career.
Mac Jones child model photos
Naturally, in wake of Jones' revelation on "Merloni & Fauria," many went searching for photos of Jones during his modeling days. They were easy enough to find.

NESN's Dakota Randall dug up a couple of shots of Jones, one in which he's wearing a tie and one in which he is carrying a tennis racket.
NFL reporter Dov Kleiman was able to find a handful of photos of Jones as well. He also found a clip of Jones participating in a fashion show from his youth.
One of Jones' advertisements actually lives on. He's still pictured on the "Adventure Landing" website, a regional theme park in Jacksonville, Fla. He appears on the "Kids Fun Center Parties" portion of the website, wearing an orange polo.
How did Mac Jones become a child model?
As Jones explained in a pre-draft interview with ESPN's Kirk Herbstreit, he tried modeling thanks to his parents.

"They never pushed me into sports, which was really cool," Jones said. "So I tried modeling, acting. My sister had done it and there's like a modeling camp and I was like, I'll go try it."

And so, Jones did. And while he said he "didn't really ever want to do that long term," he is grateful for the skills he picked up during that very early part of his career.

"It was good that I tried it and realize that I didn't necessarily want to do that but have that under my belt. Even for stuff like this," Jones said, referencing his interview and photoshoot ahead of the 2021 NFL Draft. "You're just more comfortable around the camera."
Mac Jones commercials
Try as we might, we couldn't find the commercials that Jones said might be out there. That said, if you're inclined to search for them, ESPN's Hallie Grossman gave some hints about where to look.

"[Jones] appeared in local commercials — for the zoo, a medical center, Party City, and that last one popped up for years around Halloween," she wrote in a late-2020 profile of Jones.

The Party City rabbit hole is probably the best one to jump down, as their commercials are the most readily available. The only issue with sorting through them? Most of the kids are in costumes.
Was Mac Jones the kid in that Cam Newton commercial?
This is a popular question that was raised when Jones beat out Cam Newton for the starting job with the Patriots. Was Jones the kid from that commercial with Newton? You know, the NFL "Play 60" one, where the kid threatens to take Newton's job from him in the future?

For those that need a refresher, here's the video of the advertisement.

As ironic and, frankly, mind-blowing as it would have been for Jones to be that kid, he does not play the role of "Nate." That commercial was created during the summer of 2012, ahead of Newton's second season with the Panthers. Jones turned 14 in 2012, so he would have been too old for that role even if his modeling career was ongoing.

The role of Nate was played by a then-7-year-old named James DiGiacomo. Now 16, DiGiacomo, who has acted in commercials and TV shows, spoke about the commercial after it resurfaced following Newton's release from the Patriots.

“I honestly think it’s awesome that people still bring it up,” DiGiacomo told The Eagle-Tribune. "I’ve done a lot of commercials over the years and did some TV work,” he said. “But that commercial with Cam is definitely a highlight. I didn’t realize how big it would be when we made it. But it was really cool. I’m very proud of it."

Prior to the 2021-22 season, the NBA's historic 75th season, Stephen Curry was hot on the heels of Hall of Famer Ray Allen to become the all-time leader for most 3-pointers made.

Entering the season, Curry needed 142 3-pointers needed to surpass Allen, and 12 games into the season, he's knocked off 76 of the latter's lead.
It's still early but Curry is averaging a career-high 5.4 makes per game, a shade above his previous career-high of 5.3 which he set last year in 63 games. During the 2015-16 season in which he set the all-time single-season record with 402 en route to winning his second straight MVP award, Curry averaged 5.1 makes in 79 games.
Top 10 players on the all-time leader for most made 3-pointers
Curry is one of three active players in the Top 10 with James Harden and Damian Lillard being the other two players.

 Player  3-pointers

1. Ray Allen 2,973
2. Stephen Curry 2,908
3. Reggie Miller 2,560
4. James Harden 2,489
5. Kyle Korver 2,450
6. Vince Carter 2,290
7. Jason Terry 2,282
8. Jamal Crawford 2,221
9. Paul Pierce 2,143
10. Damian Lillard 2,087
    LeBron James, who ranks 11th, could break into the Top 10 and increase the list to four active players later this season.

When will Stephen Curry surpass Ray Allen?
Curry has hit 42 of the 76 3-pointers in just five games including a red-hot shooting game against the LA Clippers, where he erupted for 45 points that started with a perfect 25-point first quarter and an overall 8-of-13 efficiency from beyond the arc and a 50-piece against the Atlanta Hawks.

As of Nov. 16, the baby-faced assassin, who is considered to be the greatest 3-pointer shooter in NBA history, needs 76 more 3-pointers to overtake Allen.
Going by his season average of 5.4 3-pointers per game, Curry would take anywhere around 14 games to jump to the No. 1 spot on the all-time charts.

That many games mean Curry could make NBA history in mid-December, provided of course that he misses no games moving forward.

Warriors upcoming 2021-22 schedule
With that projection, Curry would likely make NBA history on the road as Golden State would be on a five-game Eastern Conference road trip in mid-December.

14 games ahead on the Warriors schedule will see the team in Indiana, the birthplace of basketball. 15 games ahead will see the Warriors at the iconic Madison Square Garden playing the Knicks.

In case Curry takes a couple more games to surpass Allen, he has a couple of more iconic locations awaiting him in Boston - home of one of the oldest franchises which is tied for the most champions in NBA history - and Toronto - the capital of the birth country of James Naismith, the sport's inventor.
