BACKGROUND AND PURPOSE:

There has been a distinction made in the 2001 Canadian C-Spine Rule regarding patients 65 and older and younger than 65 years of age as far as indications for cervical spine CT scanning. We sought to determine if there are differences in the symptoms, mechanisms of injury, fracture locations, and types that are still relevant in 2024.

"Never read the comments," is a truth much-rehearsed by senior games journalists, but I have long since levelled-up past this axiom and entered into a new world of benevolent narcissism. I always read the comments, for all commenters are my children. They exist to glorify and preserve me in my dotage. True, occasionally my children say things like "I think your writing and opinions are appalling, and that you deserve to be repeatedly run over by a herd of deer", but it is the nature of children to rebel.

Research expeditions conducted at sea using a rotating gravity machine and microscope found that the Earth’s oceans may not be absorbing as much carbon as researchers have long thought.

Oceans are believed to absorb roughly 26 percent of global carbon dioxide emissions by drawing down CO₂ from the atmosphere and locking it away. In this system, CO₂ enters the ocean, where phytoplankton and other organisms consume about 70 percent of it. When these organisms eventually die, their soft, small structures sink to the bottom of the ocean in what looks like an underwater snowfall.

This “marine snow” pulls carbon away from the surface of the ocean and sequesters it in the depths for millennia, which enables the surface waters to draw down more CO₂ from the air. It’s one of Earth’s best natural carbon-removal systems. It’s so effective at keeping atmospheric CO₂ levels in check that many research groups are trying to enhance the process with geoengineering techniques.

But the new study, published on 11 October in Science, found that the sinking particles don’t fall to the ocean floor as quickly as researchers thought. Using a custom gravity machine that simulated marine snow’s native environment, the study’s authors observed that the particles produce mucus tails that act like parachutes, putting the brakes on their descent—sometimes even bringing them to a standstill.

The physical drag leaves carbon lingering in the upper hydrosphere, rather than being safely sequestered in deeper waters. Living organisms can then consume the marine snow particles and respire their carbon back into the sea. Ultimately, this impedes the rate at which the ocean draws down and sequesters additional CO₂ from the air.

The implications are grim: Scientists’ best estimates of how much CO₂ the Earth’s oceans sequester could be way off. “We’re talking roughly hundreds of gigatonnes of discrepancy if you don’t include these marine snow tails,” says Manu Prakash, a bioengineer at Stanford University and one of the paper’s authors. The work was conducted by researchers at Stanford, Rutgers University in New Jersey, and Woods Hole Oceanographic Institution in Massachusetts.

Oceans Absorb Less CO₂ Than Expected

Researchers for years have been developing numerical models to estimate marine carbon sequestration. Those models will need to be adjusted for the slower sinking speed of marine snow, Prakash says.

The findings also have implications for startups in the fledgling marine carbon geoengineering field. These companies use techniques such as ocean alkalinity enhancement to augment the ocean’s ability to sequester carbon. Their success depends, in part, on using numerical models to prove to investors and the public that their techniques work. But their estimates are only as good as the models they use, and the scientific community’s confidence in them.

The Stanford researchers made the discovery on an expedition off the coast of Maine. There, they collected marine samples by hanging traps from their boat 80 meters deep. After pulling up a sample, the researchers quickly analyzed the contents while still on board the ship using their wheel-shaped machine and microscope.

The researchers built a microscope with a spinning wheel that simulates marine snow falling through sea water over longer distances than would otherwise be practical.Prakash Lab/Stanford

The device simulates the organisms’ vertical travel over long distances. Samples go into a wheel about the size of a vintage film reel. The wheel spins constantly, allowing suspended marine-snow particles to sink while a camera captures their every move.

The apparatus adjusts for temperature, light, and pressure to emulate marine conditions. Computational tools assess flow around the sinking particles and custom software removes noise in the data from the ship’s vibrations. To accommodate for the tilt and roll of the ship, the researchers mounted the device on a two-axis gimbal.

Slower Marine Snow Reduces Carbon Sequestration

With this setup, the team observed that sinking marine snow generates an invisible halo-shaped comet tail made of viscoelastic transparent exopolymer—a mucus-like parachute. They discovered the invisible tail by adding small beads to the seawater sample in the wheel, and analyzing the way they flowed around the marine snow. “We found that the beads were stuck in something invisible trailing behind the sinking particles,” says Rahul Chajwa, a bioengineering postdoctoral fellow at Stanford.

The tail introduces drag and buoyancy, doubling the amount of time marine snow spends in the upper 100 meters of the ocean, the researchers concluded. “This is the sedimentation law we should be following,” says Prakash, who hopes to get the results into climate models.

The study will likely help models project carbon export—the process of transporting CO₂ from the atmosphere to the deep ocean, says Lennart Bach, a marine biochemist at the University of Tasmania in Australia, who was not involved with the research. “The methodology they developed is very exciting and it’s great to see new methods coming into this research field,” he says.

But Bach cautions against extrapolating the results too far. “I don’t think the study will change the numbers on carbon export as we know them right now,” because these numbers are derived from empirical methods that would have unknowingly included the effects of the mucus tail, he says.

Marine snow may be slowed by “parachutes” of mucus while sinking, potentially lowering the rate at which the global ocean can sequester carbon in the depths.Prakash Lab/Stanford

Prakash and his team came up with the idea for the microscope while conducting research on a human parasite that can travel dozens of meters. “We would make 5- to 10-meter-tall microscopes, and one day, while packing for a trip to Madagascar, I had this ‘aha’ moment,” says Prakash. “I was like: Why are we packing all these tubes? What if the two ends of these tubes were connected?”

The group turned their linear tube into a closed circular channel—a hamster wheel approach to observing microscopic particles. Over five expeditions at sea, the team further refined the microscope’s design and fluid mechanics to accommodate marine samples, often tackling the engineering while on the boat and adjusting for flooding and high seas.

In addition to the sedimentation physics of marine snow, the team also studies other plankton that may affect climate and carbon-cycle models. On a recent expedition off the coast of Northern California, the group discovered a cell with silica ballast that makes marine snow sink like a rock, Prakash says.

The crafty gravity machine is one of Prakash’s many frugal inventions, which include an origami-inspired paper microscope, or “foldscope,” that can be attached to a smartphone, and a paper-and-string biomedical centrifuge dubbed a “paperfuge.”

While reading through the list of Grammy nominees earlier I came across quite a surprise. There, competing for record of the year alongside the likes of Beyoncé's Texas Hold 'Em and Chappell Roan's Good Luck Babe, was Now and Then by The Beatles. No, to my dismay, this isn't a time travel situation, but the result of AI. 

So, here's the story of how The Beatles got nominated for two Grammys — they also snagged a best rock performance nod — 50 years after formally breaking up. It starts with a demo John Lennon recorded in the 1970s that was given to Paul McCartney, Ringo Starr and George Harrison for inclusion on the The Beatles Anthology, released in 1995. While other tracks like Free as a Bird and Real Love made it on, technology wasn't advanced enough to separate Lennon's vocals and piano without reducing the recording's quality. 

But, last year McCartney and Starr used modern machine learning technology to pull Lennon's vocals for a new track. Now and Then, released in November 2023, includes McCartney on bass, Starr on the drums, Lennon's vocals and a guitar in Harrison's style (a 1995 recording of him makes up some of the background rhythm guitar. You can watch a documentary about making the track here. 

Unsurprisingly, the song is said to be the last from the Beatles. We'll have to wait until the awards show in February to see whether or not AI will help them win another Grammy. 

Netflix is crowing that its ad-supported tier now boasts 70 million users throughout the globe, as reported by Variety. The company announced 40 million users back in May, so this is some real growth. The streamer has been slowly ramping up its ad tier, going all the way back to 2022.

Amy Reinhard, president of advertising at Netflix, says that the company continues “to see steady progress across all countries’ member bases.” She also noted that over 50 percent of new Netflix sign-ups are for these ad-supported plans. The transformation of streaming into regular TV is nearly complete.

There’s one major potential caveat. The company released the aforementioned data regarding new sign-ups, which is impressive, but there isn’t any information regarding pre-existing customers. It’s highly possible a whole lot of people downgraded from a premium tier to an ad-supported tier.

I’m one of them. I don’t mind watching an ad or two as I mindlessly stuff food down my gullet while pseudo-watching an episode of The Diplomat or The Circle. In other words, there’s an argument to be made that the ad-supported tier could be eating into the more expensive offerings.

There’s also an argument to be made that this year’s growth spurt for the ad-supported tier could attract companies with deeper ad-spending budgets, thus making up the difference. Netflix is airing live NFL broadcasts on Christmas Day, and it says it has already sold out all available commercial inventory. The streamer is actually betting big on live streams, with wrestling events, cooking shows and talk shows all airing in the near future. The company’s recent forays into audience measurement and the ad-tech space should help entice sponsors for these events.

Netflix even has plans for “themed” advertisements with certain shows. The next season of Squid Game will include a three-part linked commercial by Kia. Nothing makes me want to buy a car more than a deadly dystopian bloodsport that seems closer and closer to the real world by the day.

NEW YORK – Moves by major US fast-food chains to temporarily scrub fresh onions off their menus on Oct 24, after the vegetable was named as the likely source of an E. coli outbreak at McDonald’s, laid bare the recurring nightmare for restaurants: Produce is a bigger problem for restaurants to keep free of contamination than beef. Onions are likely the culprit in the McDonald’s E. coli outbreak across the Midwest and some Western states that has sickened 49 people and killed one, the US Department of Agriculture said late on Oct 23. The company pulled the Quarter Pounder off its menu at one-fifth of its 14,000 US restaurants. In past years, beef patties dominated the dockets of food-borne-illness lawyers, before US federal health regulators cracked down on beef contamination after an E. coli outbreak linked to Jack in the Box burgers hospitalised more than 170 people across states and killed four. As a result, beef-related outbreaks became much rarer, experts say.

Deputy Director Shen acknowledged the message but offered no further comment.
