"Time" is the most commonly used noun in the English language. The word itself is used in a __31__ of ways: wecan kill time, do time, save it, and spend it. Time even takes on a medicinal role when it comes to healing both physicaland emotional __32__ . Most of us wish we __33__ more of it, and yet time persists as an object of value, as in "Timeis money," and an enemy of every person, as in "The deadline is approaching" or "His days are __34__ ." It is, eventually,the thing__35__ kills all of us. And yet for all its pervasiveness in our everyday conversations, describing what timeis doesn't come easily.

       This month Cupid takes flight because love is in the air. And this year it smells like grease and salt. A perfume thatsmells like French fries has proven to be as irresistible as the fast-food staple after selling out almost instantly. The IdahoPotato Commission (IPC) released the limited-edition fragrance – "Frites by Idaho" – just in time for Valentine's Day,and fans couldn't wait to get their hands on a bottle. Frites by Idaho is manufactured using distilled homegrown potatoesand essential oils. Whether you and your valentine are planning to have a quiet dinner at home or will be heading outfor a fancy meal on that most romantic of days, you can make sure you crave fast food the entire time with Frites byIdaho.

       Sure this sounds silly, but think of all the words and feelings you associate with both perfume and French fries:desire, alluring, intoxicating, irresistible, tasty. Okay, maybe not that last one, but you get the idea. The great state ofIdaho isn't taking its novelty fragrance too seriously, either. The 1.7 fluid ounce bottle was available for the same priceas a side of fries, just US$1.89. Unfortunately, that's also why it sold out immediately on the IPC website. But don't giveup hope just yet, French fry romantics. You can enter a contest to win one of 10 bottles the state is giving away for free.Just head to the Idaho Potato Instagram page for how to enter.

      Even if you don't end up nabbing one, we have an idea. Just rub some French fries on your neck before your lovedone shows up. Just remember to make sure you let your fries cool down before you do that. Things are heating up thismonth, but hopefully not because of second degree burns.

       High blood pressure has been of great concern for many people nowadays. It places a severe   36   on the heart, blood vessels, and kidneys. It may   37   cause the heart to enlarge and become thickened. In some cases, the heart may fail. High blood pressure can also cause the blood vessels to overstretch, weaken, or burst; a   38   blood vessel in the brain can cause a stroke or even paralysis. The third and most serious   39   related to high blood pressure is kidney failure. When the kidneys cease to function, they no longer   40   waste products. The result of kidney failure may be serious illness, or even death.

       Is there any immortal creature in the world? Despite only being only three millimeters in diameter on average, adult versions of immortal jellyfish (Turritopsis dohrnii) have a huge party trick: they can roll back their biological clock when injured or on the verge of starvation. This means, in theory, they could live forever. Could humans harness their abilities to eradicate ageing completely?

       As scientists have known, the reason of human ageing is a process called trans-differentiation. “This is about how a fully formed specialized adult cell can become another type of specialized adult cell. It’s how a cell can adapt,” explains Dr. Maria Pia Miglietta. The exact mechanism behind trans-differentiation is still a mystery to scientists. However, as Miglietta explains, the answer will likely be found in the jellyfish’s genes. “It most certainly has something to do with the DNA,” she says. “It’s the DNA that programs a cell––certain genes being ‘turned on’ or ‘off’ will determine what sort of cell it is. We’re far away from any kind of real-world application,” says Miglietta. “But we hope that studying what happens in these jellyfish can tell us how their genes change cells––and how these changed cells integrate with others. This is the base of understanding cellular regeneration and tissue regeneration.” 

      However, there are many challenges. These jellyfish have only been studied sporadically since the early 1980s, meaning experts have only a few decades’ worth of data. While an immortal jellyfish can age in reverse, it can also be easily killed by predators including various fish, sharks, turtles and even other jellyfish. “They’re incredibly sensitive, from the water temperature to their plankton and fish egg diet,” says Miglietta. “The real paradox is they’re actually really hard to keep alive!”

       Honey is usually described as a sweet food substance. Corbezzolo honey, however, is surprisingly bitter, with notes of leather, liquorice and smoke. Born in the mountains of the Italian island of Sardinia, this extremely rare honey has a history that dates back more than 2,000 years.

       Corbezzolo honey is obtained from the flowering of the broadleaf corbezzolo shrub, known in English as the strawberry tree for its reddish-orange, strawberry-sized fruits. Despite the bitterness, it is often added to coffee to enhance the drink’s bitter aromas. The special taste also makes the honey pair perfectly with seadas, a typical Sardinian dessert, and pecorino sardo, a sweet sheep’s milk cheese. What makes the bitter honey even more special is that it is actually packed with nutrients. Rich in vitamins and minerals, it has been prized by many generations in Sardinia, known for the notably long lifespans of its inhabitants, many of whom live to more than 100 years old. It has been used in traditional medicine to suppress coughing and bring on sleep. What’s more, a 2019 study found that the honey might reduce growth of cancer cells.

      The corbezzolo’s fruits ripen slowly and the flowers’ petals unfold slowly, a delicate process that a heavy rain can easily bring to a halt. And because the flowering takes place in late autumn when the weather can be cold, rainy and windy, the bees sometimes have to struggle to make it out of their hives to collect that precious nectar. The flowers produce about half as much nectar as other flowers, so the bees have to work extra hard to collect enough. These factors make corbezzolo honey so precious that it’s hard to find outside Sardinia.
