Who has a thousand teeth?
Snails and slugs have evolved to eat just about everything; they are herbivorous, carnivorous, omnivorous, and detritivorous (eating decaying waste from plants and other animals).
There are specialist and generalist species that eat worms, vegetation, rotting vegetation, animal waste, fungus, and other snails.
Snails and slugs eat with a jaw and a flexible band of thousands of microscopic teeth, called radula.
Radulae scrape up, or rasp, food particles as the jaw cuts off larger pieces of food, like leaves, to be rasped by radulae.

Where is it possible to send a postcard underwater?
In Susami Bay, Japan, at the depth of 10 meters an underwater mailbox was set up in 1999.
In 2015, another underwater post box was installed by the Malaysian postal department at Palau Layang-Layang even deeper – at 40 meters below sea level.
The underwater post office in the town of Risor, on the southern Norwegian coast, is made out of a diving bell and is the only dry underwater post office in the world.
Established in 2003, the underwater post office the island nation of Vanuatu is located under 3 meters of water.
Normally, postcards sent from those underwater mailboxes are water-resistant or sealed in waterproof plastic bags.
The “Sea Floor” post office, in Bahamas, was the world’s first underwater post office but it existed only in 1939-1941.

Do hippos live in South America?
Although hippos live in Africa, a group of these animals can be met in South America, particularly in Colombia.
Of course, hippopotamuses are an introduced species there.
In the late 1970s, four hippos, 1 male and 3 females, lived on the grounds of the private estate of Pablo Escobar, a Colombian drug lord and narcoterrorist.
After police killed him in 1993, Colombian authorities seized the property of the “King of Cocaine” but decided to simply leave hippos at the abandoned hacienda.
As a result, these big foreigners of the South-American fauna didn’t die but started to multiply.
For the moment there are around 100 hippos in the forests and rivers of Colombia.
But their future in the new habitat is uncertain, as the national officials, society and scientists don’t agree on the benefits or threats related to the presence of these huge animals in the country.

How many times and for how long should one click the computer mouse to burn one calorie?
One calorie equals 4.2 joules.
Given that:
- the force of one click has a value of 0.5 newtons (the same force a human produces to support a mass of 50 grams)
- the distance the finger moves when clicking the button is 1 millimetre
Then multiplying that force by the distance equals 0.0005 joules.
Under these conditions, to burn one calorie you must click the mouse 10 million times.
If you clicked 10 times per second, you could burn that calorie in a mere 11.5 days.

What is phytoremediation?
Phytoremediation is the use of plants and microorganisms to clean up soil, air, and water contaminated with hazardous waste.
The term is derived from the Greek phyto (plant) and Latin remedium (restoring balance).
One of the most hyper-accumulating plants used for this process is sunflower with its capacity to remove metal compounds from deep in the soil and transport them into the stem, leaves and flower head.
It can take up high concentration of toxic materials and is able to rid a place from radioactive metals in 3-4 years.

Can hot water freeze faster than cold?
Not always, but sometimes hot water freezes faster than cold water.
Noted by scientists since Aristotle’s time (4th century BC), this phenomenon is now known as the Mpemba effect after Erasto Mpemba, a schoolboy from Tanzania. He claimed in his science class that ice cream would freeze faster if it was heated first before being put in the freezer.
So far, there is no unique theory explaining this effect.
One of the recent hypotheses is that hot water cools faster because of the bigger difference in temperature between the water and the freezer. That may help hot water reach its freezing point quicker than cold water with its natural freezing point of at least 5°C lower.

Which countries will be the world’s 10 most populous by 2100?
By 2100, India can surpass China as the world’s most populous country.
7th today, Nigeria could become the 3rd in terms of population in 80 years.
4 of the 10 most populous countries in the world of our times could no longer be among the top 10 in 2100 left behind by rapidly growing nations in Africa.
Bangladesh, Brazil, Mexico and Russia who are among the world’s 10 most populous countries today, are projected to be overtaken by the Democratic Republic of Congo, Ethiopia, Tanzania and Egypt – none of which are currently in the top 10.
In experts’ opinion, Africa’s rapid population growth will become one of the dominant stories. Of the six countries that are projected to account for more than half of the world’s population growth by 2100, five are in Africa. Half the world’s babies will be born in Africa by 2100, up from three-in-ten today.

Who is Satoshi Nakamoto?
This name is well known in the world of crypto.
It is likely to be a pseudonym for a person or a group of people who developed the first cryptocurrency in the world - bitcoin, authored the bitcoin white paper, and created and deployed bitcoin's original reference implementation.
It’s generally believed that the work on the bitcoin code began in 2007 and until mid-2010 Nakamoto continued to collaborate with other developers on the bitcoin software.
After 2010, the recognized involvement of Satoshi Nakamoto in the bitcoin project was stopped.
The identity of Satoshi Nakamoto is still unknown, but according to most of the versions this person is of non-Japanese descent.
Nakamoto could own between 750,000 and 1,100,000 bitcoin. As of November 2021, that puts his net worth at up to 73 billion US dollars, which would make him the 15th richest person in the world.

Why is Saudi Arabia importing sand from Australia?
For its important construction projects Saudi Arabia needs a lot of concrete, which is manufactured with the use of sand.
However, not all types of sand are the same and for construction purposes it is better to use coarse-grained beach sand.
Desert sand can only be used for few works in construction, but certainly not for building foundations.
Saudi Arabia has a lack of beach sand and is importing it from Australia.
In Australia sand is also mined in desert inland, what makes a difference is that central Australia was once covered by the ocean.
Therefore, the sand in Australian central deserts is a typical beach sand, polished by water for millions of years, and is ideal for construction.

Why is Saudi Arabia importing camels from Australia?
Camel meat has always played a big part in the traditional diet in Saudi Arabia, where these animals are now mostly bred for racing.
The Saudis traditionally imported camels from North Africa, but various economic and political factors led them to look elsewhere.
Australia became the new commercial partner of the Saudis because today it has a population of more than 500,000 dromedary, one-humped camels.
Australia's camels were brought over from Northern India in the 19th century to cultivate its arid back country.
In the 20th century, when animals were largely replaced by machines, the entire population of 20,000 camels was let into the wild.
Since then the Australian dromedary have been successfully reproducing, and in some areas they have even become a nuisance.

What is Africa’s “Great Green Wall”?
Africa’s “Great Green Wall” initiative is a proposed 8,000-kilometer line of trees meant to hold back the Sahara from expanding southward.
The project was launched in 2007 by the African Union, and aims to plant 100 million hectares of trees along the Sahel, the semiarid zone lining the desert’s southern edge, by 2030.
11 countries selected as intervention zones for the Great Green Wall are: Burkina Faso, Chad, Djibouti, Eritrea, Ethiopia, Mali, Mauritania, Niger, Nigeria, Senegal, and Sudan.
The project is now roughly 15 percent complete.
According to simulations made recently by scientists, the completed tree line could as much as double rainfall within the Sahel and would also decrease average summer temperatures throughout much of northern Africa and into the Mediterranean. At the same time the study found that temperatures in the hottest parts of the desert would become even hotter.

What are the earliest human-made hybrid-animals?
Cuneiform tablets and seals of Mesopotamia dating back to the late third millennium B.C. document intentional breeding of highly valued equids called “kungas” for use in diplomacy, ceremony, and warfare.
Their precise zoological classification, however, has never been conclusively determined.
But in the early 2000s from a royal burial complex dating back to 2600 B.C. at Umm el-Marra in northern Syria scientists excavated dozens of equine skeletons.
The animals, whose physical features didn’t match any known equine species, appear to be these “kungas”.
After sequencing the genomes of one of these ~4500-year-old equids, the researchers concluded that they were hybrids between female domestic donkeys and male hemippes (Syrian wild ass).
This discovery makes “kungas” the oldest evidence of humans creating hybrid animals.
But as this mystery was solved after the last hemippe perished, it’s impossible to make "kungas" again.

Evaluating how much alcohol was consumed by different nations in 2021, experts asked respondents from different countries 3 questions.
In terms of frequency of drinking, French people appeared to be the leaders, consuming alcohol on average 132 days a year. New Zealand, whose citizens drink 120 times yearly, is in the second place, and the Netherlands came third with 112 times, followed by Hungary (109) and the UK (107).
The next question was about “feeling drunk”. Here, Australians took the lead, getting drunk almost 27 times a year. Denmark and Finland share the second place with 23,8 times annually. A bit less often in 2021 got hammered the inhabitants of the US and the UK.
In the category of “feeling regret” the survey revealed new leaders. People from Ireland (28,4 times) and Poland (28,3) felt the most regret after drinking alcohol. 25-28 annual regrets were recorded in New Zealand, Romania, Spain, Italy, Canada and Hungary.

Can dogs understand that humans are speaking different languages?
To answer this question scientists scanned the brain of dogs while they were listening to audio records first in a language of their master and then in a “foreign” language.
It was found that one of the brain regions — the secondary auditory cortex — showed different neurological responses to the language that dogs were used to, and to the one, that they hadn’t heard before.
Moreover, the older the dog in the experiment was, the better they were able to distinguish between the two languages.
The research also revealed that dogs react differently to normal speech and to non-speech, that is human speech sounds that made no sense.
Scientists are now trying to establish whether this ability is dogs’ specialty, or it is a common occurrence among non-human species.

Does the size of an image matter for remembering it?
In their recent study scientists say yes.
Across experiments where participants viewed images freely without the task of memorising them, larger images were remembered about 1.5 times better than smaller ones, and the effect was proportional to the image size.
It can be explained by the fact that bigger images require more visual system processing resources. That leads to stronger registration into memory than that of smaller images processed by fewer brain resources.

Does every star have planets?
The answer of astronomers is “no”, but they add that it is a question of whether a planet was detected near a star of not.
Since 1992 when astronomers discovered the first planet outside the solar system, telescopes have spotted thousands of so-called exoplanets orbiting different stars.
Scientists now know that some stars — like the sun, as well as red dwarf stars many light-years away — are home to more than half a dozen planets, while others have none.
But what makes one star host so many planets while others fly solo?
Scientists think it may depend on the way the star was formed.
A ring of dust particles that usually surrounds young stars when they are shaping can eventually form planets.
But that model is not always the case.

What is normal blood sugar?
Normal blood sugar levels vary from person to person, but a normal range for fasting blood sugar (the amount of glucose in your blood at least eight hours after a meal) is between 70 and 100 milligrams per deciliter (mg/DL), according to the World Health Organization.
Recent studies showed that most people averaged around 82 mg/DL during the night and around 93 mg/DL during the day, and spiked to a maximum of 132 mg/DL an hour after a meal.
Blood sugar, or glucose, is a form of sugar that serves as the body's main source of energy.
We obtain glucose from the food we eat, predominantly carbohydrate-rich foods such as potatoes, rice and bread.
The absorption and storage of glucose is regulated constantly by complex processes that take place in our digestive systems.

What are volatile organic compounds (VOCs)?
Volatile organic compounds or VOCs are chemicals that are lighter than air at room temperature and are responsible for the characteristic smells of things like paint thinner and perfumes.
VOCs come from lots of human-made materials such as paints, petroleum fuels and pharmaceuticals, as well as natural sources.
If produced mostly by plants, animals, and microorganisms, they are called biogenic volatile organic compounds (BVOCs) and play an important role in the chemical processes that occur in the atmosphere.
About 10% of VOCs in the environment are human-made, and many of them, for instance benzene or perchloroethylene, can cause health problems, especially if a person is exposed to high levels for a long period of time.

Who invented Bluetooth and how does it work?
Bluetooth is a method of short-range wireless communication between electronic devices that harnesses the power of radio waves.
But if the radio spectrum stretches from 30 Hz to 300 GHz (the lower the frequency, the longer the range), Bluetooth operates at 2.4 GHz which gives it the right balance between range and data quality.
It was conceived by a Dutch engineer Dr Jaap Haartsen at the Swedish mobile giant Ericsson in the 1990s.
In 1998 the Bluetooth Special Interest Group (SIG) was formed to develop and promote the technology.
The group released Bluetooth 1.0 in 1999 and a year later it began to be used in mobile phones and desktop PCs, making its way into laptops and printers in 2001.
In the mid-2000s, the Bluetooth headset – which allowed people to communicate hands free – became a common sight.

How much horsepower can one horse produce?
Based on the term, one may assume that a horse can produce around 1 horsepower.
Linguistically, it makes sense. In reality, it's way off the mark.
The maximum output of a horse is actually much closer to 15 horsepower.
In fact, a more befitting name for the unit might be "humanpower," as the average healthy person can produce just over 1 horsepower.
Where did the term come from?
It was coined in the late 1700s by James Watt, a Scottish engineer remembered for his steam engines.
To highlight the superiority of his contraptions he decided to compare steam engines to horses and invented a unit of measurement.
Based on his observations Watt estimated that working horses were capable of pushing about 33,000 pounds 1 foot per minute (14,968.55 kilograms 1 meter per minute).
That’s how the "horsepower" unit was born.
Watt’s machines were more powerful than horses, and very few people questioned the veracity of his calculations.

Linguistically, it makes sense. In reality, it's way off the mark.
The maximum output of a horse is actually much closer to 15 horsepower.
In fact, a more befitting name for the unit might be "humanpower," as the average healthy person can produce just over 1 horsepower.
Where did the term come from?
It was coined in the late 1700s by James Watt, a Scottish engineer remembered for his steam engines.
To highlight the superiority of his contraptions he decided to compare steam engines to horses and invented a unit of measurement.
Based on his observations Watt estimated that working horses were capable of pushing about 33,000 pounds 1 foot per minute (14,968.55 kilograms 1 meter per minute).
That’s how the "horsepower" unit was born.
Watt’s machines were more powerful than horses, and very few people questioned the veracity of his calculations.
