Too much of this bacteria in the nose may worsen allergy symptoms

A type of bacteria that’s overabundant in the nasal passages of people with hay fever may worsen symptoms. Targeting that bacteria may provide a way to rein in ever-running noses.

Hay fever occurs when allergens, such as pollen or mold, trigger an inflammatory reaction in the nasal passages, leading to itchiness, sneezing and overflowing mucus. Researchers analyzed the composition of the microbial population in the noses of 55 people who have hay fever and those of 105 people who don’t. There was less diversity in the nasal microbiome of people who have hay fever and a whole lot more of a bacterial species called Streptococcus salivarius, the team reports online January 12 in Nature Microbiology.
S. salivarius was 17 times more abundant in the noses of allergy sufferers than the noses of those without allergies, says Michael Otto, a molecular microbiologist at the National Institute of Allergy and Infectious Diseases in Bethesda, Md. That imbalance appears to play a part in further provoking allergy symptoms. In laboratory experiments with allergen-exposed cells that line the airways, S. salivarius boosted the cells’ production of proteins that promote inflammation.

And it turns out that S. salivarius really likes runny noses. One prominent, unpleasant symptom of hay fever is the overproduction of nasal discharge. The researchers found that S. salivarius binds very well to airway-lining cells exposed to an allergen and slathered in mucus — better than a comparison bacteria that also resides in the nose.

The close contact appears to be what makes the difference. It means that substances on S. salivarius’ surface that can drive inflammation — common among many bacteria — are close enough to exert their effect on cells, Otto says.

Hay fever, which disrupts daily activities and disturbs sleep, is estimated to affect as many as 30 percent of adults in the United States. The new research opens the door “to future studies targeting this bacteria” as a potential treatment for hay fever, says Mahboobeh Mahdavinia, a physician scientist who studies immunology and allergies at Rush University Medical Center in Chicago.

But any treatment would need to avoid harming the “good” bacteria that live in the nose, says Mahdavinia, who was not involved in the research.

The proteins on S. salivarius’ surface that are important to its ability to attach to mucus-covered cells might provide a target, says Otto. The bacteria bind to proteins called mucins found in the slimy, runny mucus. By learning more about S. salivarius’ surface proteins, Otto says, it may be possible to come up with “specific methods to block that adhesion.”

Lots of Tatooine-like planets around binary stars may be habitable

SEATTLE — Luke Skywalker’s home planet in Star Wars is the stuff of science fiction. But Tatooine-like planets in orbit around pairs of stars might be our best bet in the search for habitable planets beyond our solar system.

Many stars in the universe come in pairs. And lots of those should have planets orbiting them (SN: 10/25/21). That means there could be many more planets orbiting around binaries than around solitary stars like ours. But until now, no one had a clear idea about whether those planets’ environments could be conducive to life. New computer simulations suggest that, in many cases, life could imitate art.
Earthlike planets orbiting some configurations of binary stars can stay in stable orbits for at least a billion years, researchers reported January 11 at the American Astronomical Society meeting. That sort of stability, the researchers propose, would be enough to potentially allow life to develop, provided the planets aren’t too hot or cold.

Of the planets that stuck around, about 15 percent stayed in their habitable zone — a temperate region around their stars where water could stay liquid — most or even all of the time.

The researchers ran simulations of 4,000 configurations of binary stars, each with an Earthlike planet in orbit around them. The team varied things like the relative masses of the stars, the sizes and shapes of the stars’ orbits around each other, and the size of the planet’s orbit around the binary pair.

The scientists then tracked the motion of the planets for up to a billion years of simulated time to see if the planets would stay in orbit over the sorts of timescales that might allow life to emerge.

A planet orbiting binary stars can get kicked out of the star system due to complicated interactions between the planet and stars. In the new study, the researchers found that, for planets with large orbits around star pairs, only about 1 out of 8 were kicked out of the system. The rest were stable enough to continue to orbit for the full billion years. About 1 in 10 settled in their habitable zones and stayed there.

Of the 4,000 planets that the team simulated, roughly 500 maintained stable orbits that kept them in their habitable zones at least 80 percent of the time.

“The habitable zone . . . as I’ve characterized it so far, spans from freezing to boiling,” said Michael Pedowitz, an undergraduate student at the College of New Jersey in Ewing who presented the research. Their definition is overly strict, he said, because they chose to model Earthlike planets without atmospheres or oceans. That’s simpler to simulate, but it also allows temperatures to fluctuate wildly on a planet as it orbits.
“An atmosphere and oceans would smooth over temperature variations fairly well,” says study coauthor Mariah MacDonald, an astrobiologist also at the College of New Jersey. An abundance of air and water would potentially allow a planet to maintain habitable conditions, even if it spent more of its time outside of the nominal habitable zone around a binary star system.

The number of potentially habitable planets “will increase once we add atmospheres,” MacDonald says, “but I can’t yet say by how much.”

She and Pedowitz hope to build more sophisticated models in the coming months, as well as extend their simulations beyond a billion years and include changes in the stars that can affect conditions in a solar system as it ages.

The possibility of stable and habitable planets in binary star systems is a timely issue says Penn State astrophysicist Jason Wright, who was not involved in the study.

“At the time Star Wars came out,” he says, “we didn’t know of any planets outside the solar system, and wouldn’t for 15 years. Now we know that there are many and that they orbit these binary stars.”

These simulations of planets orbiting binaries could serve as a guide for future experiments, Wright says. “This is an under-explored population of planets. There’s no reason we can’t go after them, and studies like this are presumably showing us that it’s worthwhile to try.”

A supernova’s delayed reappearance could pin down how fast the universe expands

A meandering trek taken by light from a remote supernova in the constellation Cetus may help researchers pin down how fast the universe expands — in another couple of decades.

About 10 billion years ago, a star exploded in a far-off galaxy named MRG-M0138. Some of the light from that explosion later encountered a gravitational lens, a cluster of galaxies whose gravity bent the light so that we see multiple images. In 2016, the supernova appeared in Earth’s sky as three distinct points of light, each marking three different paths the light took to get here.

Now, researchers predict that the supernova will appear again in the late 2030s. The time delay — the longest ever seen from a gravitationally lensed supernova — could provide a more precise estimate for the distance to the supernova’s host galaxy, the team reports September 13 in Nature Astronomy. And that, in turn, may let astronomers refine estimates of the Hubble constant, the parameter that describes how fast the universe expands.

The original three points of light appeared in images from the Hubble Space Telescope. “It was purely an accident,” says astronomer Steve Rodney of the University of South Carolina in Columbia. Three years later, when Hubble reobserved the galaxy, astronomer Gabriel Brammer at the University of Copenhagen discovered that all three points of light had vanished, indicating a supernova.
By calculating how the intervening cluster’s gravity alters the path the supernova’s light rays take, Rodney and his colleagues predict that the supernova will appear again in 2037, give or take a couple of years. Around that time, Hubble may burn up in the atmosphere, so Rodney’s team dubs the supernova “SN Requiem.”

“It’s a requiem for a dying star and a sort of elegy to the Hubble Space Telescope itself,” Rodney says. A fifth point of light, too faint to be seen, may also arrive around 2042, the team calculates.、
The predicted 21-year time delay — from 2016 to 2037 — is a record for a supernova. In contrast, the first gravitational lens ever found — twin images of a quasar spotted in 1979 — has a time delay of only 1.1 years (SN: 11/10/1979).

Not everyone agrees with Rodney’s forecast. “It is very difficult to predict what the time delay will be,” says Rudolph Schild, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., who was the first to measure the double quasar’s time delay. The distribution of dark matter in the galaxy hosting the supernova and the cluster splitting the supernova’s light is so uncertain, Schild says, that the next image of SN Requiem could come outside the years Rodney’s team has specified.

In any case, when the supernova image does appear, “that would be a phenomenally precise measurement” of the time delay, says Patrick Kelly, an astronomer at the University of Minnesota in Minneapolis who was not involved with the new work. That’s because the uncertainty in the time delay will be tiny compared with the tremendous length of the time delay itself.

That delay, coupled with an accurate description of how light rays weave through the galaxy cluster, could affect the debate over the Hubble constant. Numerically, the Hubble constant is the speed a distant galaxy recedes from us divided by the distance to that galaxy. For a given galaxy with a known speed, a larger estimated distance therefore leads to a lower number for the Hubble constant.

This number was once in dispute by a factor of two. Today the range is much tighter, from 67 to 73 kilometers per second per megaparsec. But that spread still leaves the universe’s age uncertain. The frequently quoted age of 13.8 billion years corresponds to a Hubble constant of 67.4. But if the Hubble constant is higher, then the universe could be about a billion years younger.

The longer it takes for SN Requiem to reappear, the farther from Earth the host galaxy is — which means a lower Hubble constant and an older universe. So if the debate over the Hubble constant persists into the 2030s, the exact date the supernova springs back to life could help resolve the dispute and nail down a fundamental cosmological parameter.

Khris Middleton passes Ray Allen to become Bucks all-time leader for 3-pointers made

With his first 3-pointer early in the Bucks home game against the Oklahoma City Thunder, All-Star Khris Middleton made franchise history.

He surpassed franchise legend and Hall of Famer Ray Allen for the most 3-pointers in Bucks' regular-season history.
Allen, considered one of the greatest shooters of all-time, set the tally of 1,051 3-pointers in 494 games for the Bucks between 1996 and 2003. He knocked them down at an average of 2.1 per game at an efficiency of 40.6 percent.

On the other hand, Middleton passed Allen's tally in his 566th regular-season game for the Bucks and sits atop the leaderboard with 1,054 career 3-pointers. The 30-year-old is making 1.9 3-pointers per game at a rate of 39.4 percent.
2021 has been considered quite the year for Middleton with this recent record only the cherry on top.

Just days after winning the 2021 championship with the Bucks, Middleton travelled to Tokyo to be part of Team USA's roster that went on to win the Olympic gold medal.

"To break a record like this, any franchise record is amazing," Middleton said postgame.
Both Allen and Middleton were acquired by the Bucks in trades.

Drafted by the Minnesota Timberwolves with the fifth overall pick in the 1996 Draft, Allen and Andrew Lang were traded to the Bucks for the draft rights to fourth pick Stephon Marbury.

Meanwhile, Middleton was acquired by the Bucks in 2013 along with Brandon Knight and Viacheslav Kravtsov from the Detroit Pistons in exchange for Brandon Jennings. The Pistons had drafted Middleton with the 39th overall pick in the 2012 Draft.

Yankees have strong free-agent options at shortstop, center field and starter

George Steinbrenner, the fiery, volatile Yankees owner who prioritized winning over pretty much everything else, died of a heart attack at 80 years old in July 2010, about nine months after his club won the 2009 World Series in six games over the Phillies.

The Yankees, who won seven World Series titles in Steinbrenner’s era (1973-2010) — and made the final round four other times — haven’t been back to the World Series since his death. The team from the Bronx has been good since then, with two 100-win seasons and nine trips to the playoffs — including four to the ALCS — but hasn’t broken through.
Maybe the most frustrating thing of all? The Yankees have had more regular season wins than the eventual World Series champ five times since that 2009 title: in 2010 (95, to the Giants’ 92), 2011 (97, to the Cardinals’ 90), 2012 (95, to the Giants’ 94), 2019 (103, to the Nationals’ 93) and 2021(92, to the Braves’ 88).

So, yeah, there’s plenty of motivation this offseason to add significant talent to what’s already a very talented roster. Here are two things we know about the Yankees’ offseason plans: They are going to acquire a shortstop, and payroll will increase.

Longtime GM Brian Cashman has spoken often since his club’s season ended about the need to upgrade at shortstop — Gleyber Torres is moving full time to second base — and he addressed the payroll issue speaking to reporters at the GM meetings this week.

“Well, it’s going to have to be (increasing). We don’t have a lot of stuff coming off,” Cashman said, according to the New York Post. “So obviously I’ll have some latitude.”

The Yankees stayed under the competitive-balance tax threshold in 2021, which was important to the club because penalties for going over the set number — it was $210 million in 2021 — increase sharply for every consecutive year a team is over. Getting back under the number for a season resets everything. So the Yankees are back to zero, but expect them to exceed the luxury tax — whatever the number might be — next year.

Let’s take a look at what the Yankees might do, at positions that Cashman has said are in play this offseason. We’ll start with the obvious one.

Yankees shortstop options
Back when Cashman made his initial comments saying shortstop was an “area of need” we took a dive into the most obvious options in front of the club, so we’ll just link to that story and give you the Cliff Notes version here.

Carlos Correa and Corey Seager are the two biggest names, meaning they’ll both demand massive contracts of at least 10 years. Trevor Story is coming off a down year, but the Yankees had a lot of success with one ex-Rockie (D.J. LeMahieu). Marcus Semien is a top-three AL MVP finisher this year, and he could move to second when/if one of the Yankees’ shortstop prospects is ready for the bigs. Javier Báez is an intriguing option.

“It’s certainly the year of the shortstop, certainly with a lot of high-end, talented players coming out at the same time,” Cashman said at the GM meetings.

After those five free agents, there are options the fan base probably wouldn’t like but wouldn’t be awful, such as signing Jose Iglesias or Andrelton Simmons (Cashman’s mentioned defense a couple of times) or trading for Paul DeJong.
Yankees starting pitcher options
Here’s what Cashman said on the topic at the GM meetings: “Always pitching, pitching, pitching, even though our pitching was a good thing for us this year. It’s always good to try to reinforce it and add to it if you can.”

Stealing this from a TSN piece earlier this week: The Yankees’ 2022 rotation options at the moment consist of perennial Cy Young candidate Gerrit Cole and about eight or nine pitchers who seem likely to post an ERA in the 4s if given 25 to 30 starts. It would seem unlikely that the Yankees would add a bottom-of-the-rotation starter this offseason, unless it’s an opportunistic trade or signing with low risk.

Here are four options to slot in there next to Cole:

Max Scherzer, free agent: Scherzer is 37 going on 29, still an effective and often dominant starting pitcher in the big leagues. The right-hander with three Cy Young wins had a 1.98 ERA in 11 starts with the Dodgers after arriving in a trade with the Nationals. He’ll have lots of teams bidding for his services, offering two or three-year deals with crazy-high annual salaries. A short-term, high AAV deal makes sense for the Yankees, who have to tackle the Aaron Judge extension issue sooner than later.

Justin Verlander, free agent: Sure, he’s coming off Tommy John surgery and will turn 39 during spring training. But that TJ surgery was 17 months ago, and Verlander impressed during his showcase throwing session earlier this week, sitting 94-97 with his fastball. And the idea of pairing Verlander with Cole atop the rotation has to be intriguing. Remember 2019, when those two finished 1-2 in the AL Cy Young race as teammates in Houston? You can bet the Yankees — who lost to those Astros in the ALCS that year — remember the duo well.

Marcus Stroman, free agent: Stroman was outstanding for the Mets in 2021, one of the few players on the team who was good start to finish. He made 33 starts for the club, posting a 3.02 ERA and 3.49 FIP, with only 2.2 walks per nine. Stroman pitched at least five full innings in 29 of his 33 starts — including every July, August and September outing — and only three pitchers topped that number: Zack Wheeler, Walker Buehler and Julio Urias. And you know Stroman would love the pressure of pitching under the Bronx microscope.

Kevin Gausman, free agent: Gausman was outstanding in 2021 for the Giants, posting the best season of his career. He had a 2.81 ERA/3.00 FIP in 33 starts, with a 10.6 K/9 and 2.3 BB/9. Plus, he played last year after accepting San Francisco’s qualifying offer, so he has no draft-pick compensation attached, which is nice for him. He knows the pressures of the AL East from his days with the Orioles, but now instead of facing the Yankees a couple times per season, he’d face an Orioles club that lost 110 games in 2021.

Yankees center field options
Aaron Hicks is a hard worker and a good teammate, but at this point in his career, he’s probably not a full-time center fielder, as much as the Yankees might want him to be. The club gave him a seven-year, $70 million contract after his breakthrough 2018 season — 27 homers, .833 OPS, 4.4 bWAR — but he only played 91 of the possible 324 games in 2019 and 2021, and though he played 54 of the 60 games in the pandemic-shortened 2020 season, his production wasn’t great: 0.8 bWAR, 6 homers, 21 RBI, .225 average.

The injury issues aren’t new. Hicks has been in the majors for eight 162-game seasons, and he’s played more than 97 games only twice. His contract has four remaining years, but using “contractual obligation” to determine starters isn’t the best way to build a World Series team. Cashman acknowledged as much at the GM meetings.

“He’s going to finish off his rehab and he very well might be our starting center fielder, but again I’m going to be open-minded and evaluate all opportunities,” Cashman said. “We just want to make sure we put the best team out there. There are no guarantees right now, for anybody. … Aaron Hicks was hurt, so he’s been off the board. He might play some winter ball, we’ll see. In the meantime, center field was an area of concern this past year because of his injury.”

Here are four options:

Starling Marte, free agent: He’s heading into his Age 33 season, but Marte still is a great player. He led the majors with 47 stolen bases despite playing just 120 games combined for the Marlins and A’s, and he posted a career-best on-base percentage (.381) and OPS+ (131), plus a bWAR of 4.0 or better for the sixth time in his career. He’s also an outstanding defensive center fielder. A three-year deal with a relatively high AAV seems reasonable.

Chris Taylor, free agent: Playing center field is just one of his many talents. The Yankees could sign him with the idea that he’s the starting center fielder, but they’d also be getting a replacement third baseman if Gio Urshella gets hurt, a replacement shortstop if the new shortstop gets hurt, a replacement second baseman if Torres goes down and he could probably catch, too, if Gary Sanchez gets hurt (OK, not the last one, but you get the picture).

Joey Gallo, on the roster: The Yankees could decide to keep this one in house, with Gallo — yes, he’s a large human but he’s an excellent defensive outfielder who has played 55 games in center in his career — as the fallback option if the club decides that Hicks is ready to take the full-time role this spring.

Brett Gardner, free agent: Yep, Gardner could possibly come back, even after both sides declined their options this offseason. Another year of “hope Hicks is healthy, but at least we have Gardy” might not be the most appealing, but if the Yankees spend big at shortstop and in the rotation, that could what winds up happening.

Don't expect Carlos Correa's take on Derek Jeter to be a deal-breaker for Yankees

Carlos Correa's statement last week that Yankees legend Derek Jeter "did not deserve" any of his five Gold Gloves wouldn't be as controversial if Correa wasn't one of the hottest free agents on the market this offseason and would solve the Yankees' current shortstop problems. Goodness knows, he isn't the only person who has said such a thing.

Correa, 27, won a Rawlings Platinum Glove this year as the best fielder, regardless of position, in the American League. He also collected a Gold Glove (his first). He racked up 21 defensive runs saved, most in MLB among shortstops and seven more than runner-up Andrelton Simmons. He's no slouch in the field.

In fact, DRS was a large part of Correa's seeming diss of Jeter on an episode of "Me Gustan Los Deportes" ("I Like Sports"), a Facebook Live show hosted by former MLB star Carlos Baerga. Correa used Jeter's career numbers to illustrate the point that evaluation of defense has changed over the years because of the rise of advanced stats such as DRS.

"Derek Jeter. How many Gold Gloves did he win? Five. I think he won five. Derek Jeter did not deserve any of them," Correa, who has been an admirer of Jeter's, said in Spanish. "You know how much Derek Jeter's [DRS was] in his career? Negative 160 [actually, negative 162, per Fangraphs]. In his career. But your eyes can lie to you. Your eyes can lie to you. His fame . . ."
Heard in isolation, that snippet was a shot at "The Captain." And it came out during a period when the Yankees can bid on Correa, who reportedly turned down an offer recently of five years and $160 million from his old club, the Astros.
Jeter's fame served him well over his two decades with the Bronx Bombers, but it's not why AL managers and coaches voted him a Gold Glove winner in 2004, 2005, 2006, 2009 and 2010 when he was roaring through his 30s. (Critics might say his jump throws and solid hitting were why.) He had one positive DRS figure his entire career, a plus-3 in 2009. Sabermetrics didn't help to decide fielding awards then, however; the eye test was still king.

Jeter passed the test. Correa noted that the eyes can lie.

Jeter's enduring popularity led some Yankees fans to rush to his defense Monday against Correa, who is a sworn enemy in parts of New York because he played for the cheating Astros in 2017, when they beat the Yankees in the ALCS.
But other fans — and, most importantly, Yankees management — know that Correa would be a massive upgrade over Gleyber Torres, Tyler Wade or any other internal candidate. Yankees shortstops tied for 25th in the majors this year with minus-14 DRS. Adding a top-notch player at the position is an offseason priority.

And Correa is top-notch. He heads a loaded free-agent shortstop class that also includes Corey Seager, Javier Baez, Marcus Semien and Trevor Story. The Yankees won't reject him because of a quote that may have been taken out of context. They would be glad to have him play Jeter's position — and very happy if he plays it better than Jeter did.

Charlotte Hornets showing signs of growth on the defensive end as they continue Eastern Conference rise

The Charlotte Hornets were clinging to a 99-98 lead with five minutes to play against Golden State. The easily excitable Hornets play-by-play caller Eric Collins was crackling with anticipation on every dribble in what was looming as a memorable early season win.
Despite the hope in the building from the home crowd, you looked at the Warriors lineup and saw the players on the floor.

Stephen Curry. Draymond Green. Andre Iguodala.

To that point, Curry had been decently held, tallying just 24 points. But surely he would break loose…

Charlotte, who were 7-7 coming into the night needed a big win. A highlight machine team, the Hornets play has been inconsistent through the early part of the season.

Rather than crumble under the pressure, the Hornets locked in on the defensive end, stifling the Warriors and inparticular Curry. Golden State would manage just four points the rest of the way, with Curry going scoreless on 0-for-4 shooting from the floor.

Try as he might, Curry couldn't shake loose from multiple Charlotte defenders and on this night at least, he failed to knock down the miraculous attempts.

The 106-102 win is big, but the way they executed defensively feels like something head coach James Borrego can lean on moving forward.

"We're trying to become a more consistent team in our effort, our execution. I think tonight was a good example of that," Borrego said.

"I think we were just locked in defensively. Our ball pressure, our hands, our activity. I thought our group was fantastic on Steph. He banks one in, you move on, he's going to make some of those shots. I thought in general we made it very tough on him tonight. The guys in that locker room deserve the credit, they were locked in from minute one."

An explosive offensive team, the Hornets have quickly become the darlings of NBA League Pass, with the LaMelo Ball and Miles Bridges pairing providing as many highlight reel plays as any duo since the beginning of last season.

Aside from the jaw dropping passes and dunks, Ball and Bridges possess serious size, length and versatility that should bode well for a modern defense to have success.

In a positive sign, the Hornets have a defensive rating of 105.3 across 268 minutes when on the floor with big man Mason Plumlee.

As with all young teams, the defensive side of the ball usually develops after the offense, but for tonight at least, the Hornets flashed an ability to lock an opposition team down when they needed it most.

"To be a good team you've got to be able to close. I think we closed out tonight and it was more on the defensive end."

Now it's about consistency.
