A hole in your throat is nothing to sneeze at, as shown by a case report recently published in BMJ Case Reports. And the case report showed the dangers of pinching your nose and closing your mouth in an attempt to stifle a sneeze. A man in his 30s tried doing this and was left with a hole is his trachea, which can be a hole lot of trouble.
This man who had a history of allergies was wearing a seat belt while driving his car when he felt the need to sneeze and in a pinch tried to keep the sneeze from exiting from either his nostrils or his mouth. This led to quite a pressure-filled situation. Normally, sneezing can generate a pressure of one to two kilopascals in the upper airways which, in turn, can blast air and accompanying gunk out through your nose and mouth. But guess what happens when you pinch your nose shut and keep your mouth closed at the same time? Rather than rushing out of these holes, the air has no place to go. That can build up pressure your the upper airways that is up to 20 times higher than what a released sneeze would generate.
After this sneezus interruptus, the man began experiencing severe neck pain and eventually ended up in the emergency department of Ninewells Hospital in Dundee, UK. The four authors of the case report (Rasads Misirovs, Gary Hoey, Calum Carruthers and Samit Majumdar) work at this hospital. There doctors found the man’s neck to be swollen on both sides. An X-ray of his neck revealed evidence of air where it wasn’t supposed to be, and a CT of the neck and chest with contrast showed a 2 mm by 2 mm by 5 mm in his trachea, otherwise known as his windpipe.
In this episode, my guest is Dr. Robert Lustig, M.D., neuroendocrinologist, professor of pediatrics at the University of California, San Francisco (UCSF), and a bestselling author on nutrition and metabolic health. We address the “calories in-calories out” (CICO) model of metabolism and weight regulation and how specific macronutrients (protein, fat, carbohydrates), fiber and sugar can modify the CICO equation. We cover how different types of sugars, specifically fructose, sugars found in liquid form, taste intensity, and other factors impact insulin levels, liver, kidney, and metabolic health. We also explore how fructose in non-fruit sources can be addictive (acting similarly to drugs of abuse) and how sugar alters brain circuits related to food cravings and satisfaction. We discuss the role of sugar in childhood and adult obesity, gut health and disease and mental health. We also discuss how the food industry uses refined sugars to create pseudo foods and what these do to the brain and body. This episode is replete with actionable information about sugar and metabolism, weight control, brain health and body composition. It ought to be of interest to anyone seeking to understand how specific food choices impact the immediate and long-term health of the brain and body.

Despite the company’s commitment to making its founder’s dream come true, the virtual reality market is contracting.
Sales of VR headsets and augmented reality glasses in the U.S. plummeted nearly 40% to $664 million in 2023, as of Nov. 25, according to data shared with CNBC by research firm Circana. That’s a much steeper drop than last year, when sales of AR and VR devices slid 2% to $1.1 billion.
The two-year decline underscores Meta’s continuing challenge in bringing the immersive technology out of a niche gaming corner and into the mainstream. While Zuckerberg said, in announcing Facebook’s pivot to Meta in late 2021, that it would likely take a decade to reach a billion users, he may need to start showing more optimistic data to appease a shareholder base that’s been critical of the company’s hefty and risky investments.
Could Earth end up with a runaway greenhouse effect like Venus someday, and what could this mean for finding life on exoplanets? This is something a recent study published in Astronomy & Astrophysics hopes to address as an international team of researchers used a 3D global climate model to investigate if Earth is destined to develop a runaway greenhouse effect like the planet Venus, which precious studies speculate was once much like Earth long ago. This study holds the potential to bring awareness of the long-term consequences of climate change and what steps can be taken to mitigate the effects.

“Until now, other key studies in climatology have focused solely on either the temperate state before the runaway, or either the inhabitable state post-runaway,” said Dr. Martin Turbet, who is a research scientist at CNRS laboratories of Paris and Bordeaux and a co-author on the study. “It is the first time a team has studied the transition itself with a 3D global climate model and has checked how the climate and the atmosphere evolve during that process.”
SpaceX’s next Starship prototype is undergoing tests and preparations for launch, while other companies like Rocket Lab and ULA are also making progress in their space endeavors.
Tesla’s innovative design and manufacturing processes, as well as their focus on safety features, set them apart from traditional automakers and position them as a formidable competitor in the industry.
