How cockroach can live without head ?
A cockroach can live for a week without its head. Due to their open circulatory system, and the fact that they breathe through little holes in each of their body segments, they are not dependent on the mouth or head to breathe. The roach only dies because without a mouth, it can't drink water and dies of thirst.

How long is the earth's circumference?
The circumference of Earth at the equator is about 24,902 miles (40,075 km), but from pole-to-pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around. This shape, caused by the flattening at the poles, is called an oblate spheroid.

Why do flamingos stand on one leg?
Flamingos often stand on one leg, the other leg tucked beneath the body. The reason for this behaviour is not fully understood. Recent research indicates that standing on one leg may allow the birds to conserve more body heat, given that they spend a significant amount of time wading in cold water.

Can a shark swim backwards?
Unlike fish, sharks cannot stop suddenly or swim backwards. A shark's pectoral fins cannot bend upwards like a fish, limiting its swimming ability to forward motion. If a shark needs to move backwards, it uses gravity to fall, not swim backwards.

How long do dogs live on average?
Nearly 40% of small breed dogs live longer than 10 years, but only 13% of giant breed dogs live that long. The average 50-pound dog will live 10 to 12 years. But giant breeds such as great Danes or deerhounds are elderly at 6 to 8 years.

What are vaccine passports?
News- Vaccine passports for international travel? Why you may need one soon?
The idea is modelled on the proof of vaccination that several countries required even before the pandemic. Travellers from many African countries to the US or India are required to submit proof that they have been vaccinated against diseases such as yellow fever.
Even though the nomenclature comes from passports, most vaccine passports have been envisaged as digital documents. They are supposed to function as proof that the holder has been vaccinated against Covid-19 and is, therefore, “safe”.

What is 'Twilight Zone' of oceans?
Twilight zone in oceans is the part at the depth of 200 to 1000 metres. These depths are given such a name because water at these depths receive less sunlight. A study by Cardiff University has revealed that global warming is adversely affecting life in the twilight zone of oceans.
As one goes deeper in ocean, organisms obtain nutrition via different modes. One of them is the 'marine snow'. Marine snow is simply food and nutrient particles sinking deeper in water after they fall into it from air.

Will the coronavirus ever go away?
No one knows for sure. Scientists think the virus that causes Covid-19 may be with us for decades or longer, but that doesn't mean it will keep posing the same threat.
The virus emerged in late 2019 and it's difficult to predict how it will behave over the long term. But many experts believe it's likely the disease will eventually ease from a crisis to a nuisance like the common cold.
That would happen as people build up immunity over time, either through infection or vaccination. Other viruses have followed a similar path.
The 1918 flu pandemic could also offer clues about the course of Covid-19.

What Is the Hubble Space Telescope?
News: Hubble Space Telescope beams back mesmerising image of a nebula!
The Hubble Space Telescope is a large telescope in space. NASA launched Hubble in 1990. Hubble is as long as a large school bus. It weighs as much as two adult elephants. Hubble travels around Earth at about 5 miles per second.
Hubble faces toward space. It takes pictures of planets, stars and galaxies. Hubble has seen stars being born. Hubble has seen stars die. It has seen galaxies that are trillions of miles away. Hubble also has seen comet pieces crash into the gases above Jupiter.
Scientists have learned a lot about space from Hubble pictures. The pictures are beautiful to look at too.
Question: What Makes Hubble Different From Telescopes on Earth?

What is Sandstorm or Dust Storm?
News: Beijing witnesses worst sandstorm in a decade, causing severe air pollution
A dust storm, also called sandstorm, is a meteorological phenomenon common in arid and semi-arid regions. Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface. Fine particles are transported by saltation and suspension, a process that moves soil from one place and deposits it in another.
Drylands around North Africa and the Arabian peninsula are the main terrestrial sources of airborne dust.
The term sandstorm is used most often in the context of desert dust storms, especially in the Sahara Desert, or places where sand is a more prevalent soil type than dirt or rock, when, in addition to fine particles obscuring visibility, a considerable amount of larger sand particles are blown closer to the surface. 🌪

Where did all of Mars' water go?
News: Missing water on Mars may not have 'escaped to space', could be lurking underground: Study
Billions of years ago, Mars was home to lakes and oceans — but where all the water went to transform the planet into the desolate rock we know today has been something of a mystery. Most of it was thought to have been lost to space, but a new study funded by NASA proposes that it didn't go anywhere but is trapped within minerals in the crust. "We're saying that the crust forms what we call hydrated minerals, so minerals that actually have water in their crystal structure.

The rankings are based on polling (Gallup World Poll) which looks at six variables: GDP per capita, social support, healthy life expectancy, freedom, generosity, and absence of corruption.
Best Performers
Finland(1st), Denmark(2nd), Switzerland(3rd), Iceland(4th), Netherlands(5th)
Worst Performers
Lesotho(145th), Botswana(146th), Rwanda(147th), Zimbabwe(148th), Afghanistan(149th)

What is Permafrost?
Permafrost is any ground that remains completely frozen—32°F (0°C) or colder—for at least two years straight. These permanently frozen grounds are most common in regions with high mountains and in Earth’s higher latitudes—near the North and South Poles.
Permafrost covers large regions of the Earth. Almost a quarter of the land area in the Northern Hemisphere has permafrost underneath. Although the ground is frozen, permafrost regions are not always covered in snow.
What Is Permafrost Made Of?
Permafrost is made of a combination of soil, rocks and sand that are held together by ice. The soil and ice in permafrost stay frozen all year long.
Permafrost soils also contain large quantities of organic carbon—a material leftover from dead plants that couldn’t decompose, or rot away, due to the cold and minerals.

Largest asteroid to pass by Earth this year
Asteroid 2001 FO32 ( see image) makes its closest approach to Earth, giving astronomers the chance to study the rock as it passes.
The largest asteroid to pass by Earth this year has made its closest approach, posing no threat of a cataclysmic collision but giving astronomers a rare chance to study a rock formed during the beginning of our solar system.
The asteroid was two million kilometres (1.25 million miles) away at its nearest, according to NASA – more than five times the distance between the Earth and the Moon but still close enough to be classified as a “potentially hazardous asteroid”.

Satellite ELSA-d to Clean up Space Debris
ELSA-d is the world’s first commercial mission that will demonstrate technologies for space debris docking and removal.
ELSA-d's servicer satellite has been developed to safely remove debris objects from orbit, equipped with proximity rendezvous technologies and a magnetic docking mechanism.
ELSA-d consists of two satellites stacked together -- one is a servicer designed to safely remove debris from orbit and the other a client satellite that will serve as a piece of replica or mock debris.
