Survey: Trust in science is high, but misinformation is a threat
Trust in science is rising worldwide, according to a 3M-backed survey released Tuesday, and more people expect it to solve the world’s problems.
But the fifth annual 3M State of Science Index also showed many are worried that misinformation could lead to more public health crises, greater societal divisions and lack of action on climate change.
“It’s really good to see that trust in science is high, and that’s true in America and around the world, but misinformation threatens scientific credibility,” Jayshree Seth, 3M’s corporate scientist and chief science advocate, said in an interview. “It’s not simply a matter of communicating facts, data and evidence. We need to build that relationship with the public.”
Spanish Aquaer develops a machine that extracts drinking water from thin air
There is nothing more essential to life on Earth than water. It’s a cruel irony that the majority of the world’s surface is covered in water, yet only a fraction of it is suitable for human consumption. Around 785 million people globally still lack access to clean, safe drinking water.
With an aim to provide drinking water where no other sources of water are available, a Spanish company, Aquaer, has devised a machine capable of extracting drinking water from thin air. Invented by Enrique Veiga, the 82-year-old engineer, the machine can operate even in areas where humidity is low, as in the desert.
The machines utilize the same principle that causes condensation in air-conditioning units. It uses electricity to cool the surrounding air, and then it takes the process a step further by condensing the water vapor.
Air Protein creates fake steak from CO2 that replicates taste and texture of meat
California-based startup Air Protein has developed a meat alternative called Air Meat, which is made using microbes that turn recycled carbon dioxide into protein.
Described by Air Protein as “the meat of tomorrow”, Air Meat was designed to replicate the flavour and texture of real meat products such as steak.

This superjumbo is the biggest plane Airbus has tested on sustainable fuel.
The fuels release as much carbon dioxide (CO2) when combusted as they absorb from the atmosphere when produced, so no additional CO2 emissions are generated.
