Ever heard of frazil ice? If not, you're not alone! However, for those who love the great outdoors, especially avid hikers, understanding a bit about this peculiar form of ice and its potential dangers can be crucial.
Frazil ice often goes unnoticed despite its appearance – resembling a mix of snow and ice or slushy snow. On a closer look, it manifests as tiny particles, typically around 1mm or smaller, often taking the shape of thin disks or forming slushy circles known as pancake ice, particularly in windy and rough sea conditions.
The term "frazil" finds its roots in the French word fraisil, translating to cinder.
So, how does frazil ice come into existence? Turbulence in water plays a pivotal role, occurring when the water becomes "supercooled" as surface water loses heat to the cold air above, requiring the water temperature to be just below freezing.
According to the Yosemite National Park's Facebook page, frazil ice occurs when fast-moving, turbulent water gets so cold that it resembles a slushie but poses a more perilous threat than a delicious treat.
Scientifically, as explained by the Iowa Institute of Hydraulic Research, frazil ice forms in flowing or turbulent water that becomes supercooled due to heat transfer to the overlying air. The intensity of turbulence and the rate of temperature drop in the water determine the amount and size of ice particles formed.
Frazil ice tends to grow rapidly once initiated. As reported by the Treatment Plant Operator magazine, it first forms, then multiplies, and eventually attaches to underwater structures like water system intakes.
Where might you come across frazil ice? This phenomenon is exclusive to cold weather and requires clear, cold nights with some wind to induce water turbulence. It can appear in rivers, lakes, reservoirs, and oceans. Frazil ice is more likely to be observed in regions with extreme winters, such as Canada, the US, Antarctica, and the Baltic Sea.
Hey everyone! I've got some eye-opening insights from Dr. Mijin Brown, also known as Dr. Midge on TikTok. Turns out, a couple of foods we thought were super healthy might not be as wholesome as we believed. Let's dive into the details.
1. Oat Milk: The Not-So-Healthy Coffee Companion
Starting off with oat milk – the go-to for coffee enthusiasts. Dr. Midge is here to bust the myth that it's a health champion. A cup is packing 15g of carbs, and that's not even counting the sugary ones. To add to that, many store-bought brands throw in preservatives and thickeners that don't do our gut health any favors.
2. Porridge (Oatmeal): A Carb-Loaded Controversy
Next on the list is porridge, or as they call it in the US, oatmeal. Dr. Midge spills the beans – a hefty 62 grams of carbs in a single cup, even though it gives you a decent fiber boost with 8 grams. She's straightforward – "Not worth it, guys." But she throws in a shoutout for coarse oatmeal – keeping it real.
Hey, folks! So, here's the deal – turns out a bunch of people in the UK are running low on Vitamin D. You know, that sunshine nutrient that does wonders for your heart and all that jazz.
Now, the signs that you might be a bit Vitamin D-deficient? Well, they're not exactly subtle. Feeling like a total zombie? Check. Losing more hair than you'd like? Yep, that's on the list too. The Mirror spilled the beans on these symptoms, but there's more to it.
Vitamin D isn't just about keeping you awake and your hair intact. It's pulling double duty with blood clotting, giving your immune system a pep talk, and even helping those muscles grow. Now, here's the kicker – experts are waving the flag, saying, take a daily 10 microgram vitamin D supplement!" Why? 'Cause apparently, your average diet isn't throwing enough of it your way, and the British weather isn't exactly the sunshine express.
So, what are these nine signs of a Vitamin D shortage? According to the smart minds at the University of Nebraska University Health Centre:
1. Fatigue
2. Not sleeping well
3. Bone pain or achiness
4. Depression or feeling blue
5. Hair loss
6. Muscle weakness
7. Loss of appetite
8. Catching every bug in town
9. Rocking a paler shade than usual
Céline Dion's sister recently revealed uncertainties surrounding the singer's future music career due to her diagnosis with an autoimmune disease known as stiff person syndrome (SPS). This rare autoimmune neurological disorder induces progressive muscle stiffness and painful spasms in the lower back, legs, and torso, with symptoms fluctuating between worsening and temporary improvement. SPS can lead to chronic pain, falls, and diminished mobility over time.
Understanding Stiff Person Syndrome
Incidence and Demographics:
SPS is an exceedingly rare condition, affecting an estimated one to two individuals per million. It typically manifests in people aged 40–50, although cases involving children have been documented. Originally labeled stiff man syndrome, this autoimmune disorder predominantly affects women, following the common trend seen in many autoimmune conditions.
Causes and Autoimmune Connection:
Due to the disorder's rarity, research into the precise biological mechanisms behind SPS is still in its early stages. Current evidence suggests an autoimmune reaction where the body erroneously attacks healthy tissues. Around 80% of SPS patients have detectable autoantibodies in their blood, targeting nerve cells that produce the neurotransmitter GABA in the brain. GABA plays a crucial role in dampening brain activity and regulating motor neurons. The theory posits that reduced GABA availability prompts overactive neurons to signal continuous muscle contractions or spasms.
Moreover, many SPS patients also contend with other autoimmune diseases such as type 1 diabetes, vitiligo, or pernicious anemia.
Diagnosis Challenges
Misdiagnosis and Overlapping Symptoms:
Due to its rarity, SPS is often misdiagnosed as Parkinson's disease, and its symptoms overlap with those of conditions like multiple sclerosis, fibromyalgia, anxiety, and phobias. Diagnosis involves blood tests to identify autoantibodies, although some patients may not test positive. Additionally, MRI and CT scans are employed to rule out conditions that might be confused with SPS.
Osteoporosis, a widespread disorder affecting millions globally, renders bones brittle and prone to fractures even from minor traumas. Various factors, including age and diet, play pivotal roles in the development of this condition.
1. Dietary Impact on Osteoporosis:
- Studies reveal that certain foods can leach calcium, a critical element for bone health.
- Age is a significant factor, with older individuals experiencing more bone mass loss.
2. Alcohol and Bone Health:
- Alcohol consumption negatively affects bone health.
- Increased intake can hinder the absorption of essential nutrients crucial for bone health.
- Orthopedist Liz Matskin recommends limiting daily alcohol intake to mitigate its impact.
3. Caffeine and Bone Health:
- Caffeine, present in coffee and other beverages, worsens bone health.
- It increases calcium loss and decreases absorption.
- Consider decaffeinated alternatives to protect bone density.
Automobile thieves are increasingly using technology that was once marketed as a convenience for drivers. Nowadays, since it's silent and quick, relay theft is the method of choice for auto theft. Theftsters now use a technique called "bounce and roll" to steal goods instead of "smash and grab," signaling from the house keys to the car and driving off.
Since the Range Rover achieved the dubious title of being the most stolen car in Britain, keyless car crime has been making headlines once more. In response, JLR has declared plans to invest £10 million in enhancing security and providing owners of both new and used Range Rovers with a special auto insurance program.
However, keyless car crime does not only affect luxury SUVs. After years of declining car thefts, the so-called "relay attack" has emerged as the most popular method of car theft.
What is keyless car theft, and how can you protect yourself from this advanced, 21st-century crime
What does "keyless car theft" mean?
- Because a relay attack is so easy to execute, owners of cars equipped with keyless entry should be especially concerned. Once an automobile has been identified as a target, two thieves collaborate to steal it, frequently from outside the owner's house, using electronic signal relay devices.
- While the other person stays close enough to the house for a device to detect a signal from the key fob, one person remains by the targeted car.
- By transferring this signal to a second box and placing it next to the car or in the other person's hands, it is possible to trick the car into believing that the key is inside.
- The thieves can simply press a button to start the car once the doors are unlocked, allowing them to take off. For less than £100, you can purchase the electronic hardware needed to steal an automobile online, which is a highly enticing offer for would-be burglars.
How to stop automobile theft involving keyless entry
- Drivers are advised to exercise caution when at home because keyless car theft incidents usually happen in residential areas, particularly at night. Even though auto theft is increasing, there are precautions you can take to keep your car safe.
- Relay device Signals can travel through walls, doors, and windows, but they cannot pass through metal. To protect your car from an attack, keep your keys in a metal container, a wallet that blocks signals, or even a microwave.
- A Faraday bag, also called a signal blocker pouch, can be bought online for about £10. But do give it a try to make sure the signal is truly blocked. Although keeping your keys out of reach of the front door or window is a good idea, you should give it some thought before carrying the keys upstairs or concealing them in a bedroom. Allowing a thief to take the car is preferable to risking your safety or the safety of your family if they are determined to break into the house in order to obtain the keys.
