Though, water covers around two-thirds of the earth's surface but water is still a scarce resource as only 1% of world's water is available as drinking water. With due availability of land and air all around, civilizations before have always moved/expanded in search of required drinking water.
Drinking water based on water cycle of earth (ocean-heat evaporation-cloud-rain-ocean) and then available from natural resources on earth is dwindling with time due to many reasons along with increasing population. People have already shifted to the use of smart technologies to transport, clean, uplift drinking water from other different sources but all these water resource technologies have their own geographic region specific limitations in general and for hilly and desert regions in particular. Earth's atmosphere holds six times more fresh water than all of its rivers combined, so, if it is possible technologically to harvest that water, in areas where people have no other fresh water source, can prove to be a wonder.
Atmospheric water extracting devices extract potable water from the air, either through condensation, exposing the air to desiccants (water-absorbing substances), or by pressurizing the air. With the development of science and technology, scientists and engineers are proposing different technologies to extract water from thin air (from fog) which will help people in getting enough drinking water at location specific with low cost. There are four main methods for extracting water from the atmosphere:
Fog nets: setting up physical nets in humid environments to collect the water in the air
Dew plates: using temperature differences to encourage water to condense on metal plates
Sorbents: using chemicals to absorb water from the air, and then heating the material to extract the water

Non-Thermal Plasma Applications in Biomedical and Medicine fields
The fishing and marine industry plays a crucial role in providing food, livelihoods, and economic prosperity worldwide. However, one significant challenge that the industry faces is biofouling - the accumulation of marine organisms on submerged surfaces.
Misbeliefs related to Food, Nutrition and Cancer
There are so many myths about food and nutrition related to cancer and it's difficult to find out the truth. Often the information shared by people and on internet is very confusing. One cannot clarify the fact about the statement.
Scientists Have Grown Diamonds in Just 150 Minutes
Natural diamonds take billions of years to form in the extreme pressures and temperatures deep underground. Synthetic forms can be produced far quicker, but they typically still require some intense squishing for up to several weeks.
In a warming world, climate scientists consider category 6 hurricanes
For more than 50 years, the National Hurricane Center has used the Saffir-Simpson Windscale to communicate the risk of property damage; it labels a hurricane on a scale from Category 1 (wind speeds between 74-95 mph) to Category 5 (wind speeds of 158 mph or greater).
New antibiotic class effective against multidrug-resistant bacteria
Scientists at Uppsala University have discovered a new class of antibiotics with potent activity against multidrug-resistant bacteria, and have shown that it cures bloodstream infections in mice. The new antibiotic class is described in an article in the scientific journal PNAS.
Modeling the origins of life: New evidence for an 'RNA World'
Charles Darwin described evolution as \"descent with modification.\" Genetic information in the form of DNA sequences is copied and passed down from one generation to the next. But this process must also be somewhat flexible, allowing slight variations of genes to arise over time and introduce new traits into the population.
European lawmakers pass world's first major act to regulate AI
The European Union's parliament on Wednesday approved the world's first major set of regulatory ground rules to govern the mediatized artificial intelligence at the forefront of tech investment.
Scientists are making significant progress towards reviving the woolly mammoth
A company aiming to bring extinct animals back from the dead said it has taken an elephant-sized step toward genetically resurrecting the woolly mammoth, a wild if contentious goal to repopulate the Arctic tundra with a missing titan.
Probiotic feed additive boosts growth, health in poultry in place of antibiotics
Antimicrobial resistance is an increasingly serious threat for public health, and the use of anti-microbials in livestock feed has been a major contributing factor in the emergence and spread of antimicrobial resistance to many drugs, according to the U.S. National Institutes of Health.
Can animals count?
Research team from The Chinese University of Hong Kong (CUHK) Faculty of Medicine (CU Medicine) has made a groundbreaking discovery regarding number sense in animals by confirming the existence of discrete number sense in rats, offering a crucial animal model for investigating the neural basis of numerical ability and disability in humans.
