Balls of human brain cells linked to a computer have been used to perform a very basic form of speech recognition. The hope is that such systems will use far less energy for AI tasks than silicon chips. “This is just proof-of-concept to show we can do the job,” says Feng Guo at Indiana University Read more about AI made from living human brain cells performs speech recognition[…]

[…] Using realistic ecological modeling, scientists led by Western Sydney University’s Jürgen Knauer found that the globe’s vegetation could actually be taking on about 20% more of the CO2 humans have pumped into the atmosphere and will continue to do so through to the end of the century. “What we found is that a well-established Read more about Plants may be absorbing 20% more CO2 than we thought, new models find[…]
[…] Every clock has two fundamental properties: a certain precision and a certain time resolution. The time resolution indicates how small the time intervals are that can be measured—i.e., how quickly the clock ticks. Precision tells you how much inaccuracy you have to expect with every single tick. The research team was able to show Read more about Limits for quantum computers: Perfect clocks are impossible, research finds[…]
Dirty air killed more than half a million people in the EU in 2021, estimates show, and about half of the deaths could have been avoided by cutting pollution to the limits recommended by doctors. The researchers from the European Environment Agency attributed 253,000 early deaths to concentrations of fine particulates known as PM2.5 that Read more about Toxic air killed more than 500,000 people in EU in 2021, data shows[…]

[…] In recent years, some researchers have been puzzled upon finding that water in their experiments, which was held in a sponge-like material known as a hydrogel, was evaporating at a higher rate than could be explained by the amount of heat, or thermal energy, that the water was receiving. And the excess has been Read more about In a surprising finding, light can make water evaporate without heat[…]
The Library of Babel is a place for scholars to do research, for artists and writers to seek inspiration, for anyone with curiosity or a sense of humor to reflect on the weirdness of existence – in short, it’s just like any other library. If completed, it would contain every possible combination of 1,312,000 characters, Read more about Library of Babel Online – all books ever written or ever to be written, all images ever created or ever to be created can be found here[…]
A team of scientists at Northwestern University has developed a synthetic version of melanin that could have a million and one uses. In new research, they showed that their melanin can prevent blistering and accelerate the healing process in tissue samples of freshly injured human skin. The team now plans to further develop their “super Read more about ‘Super Melanin’ Speeds Healing, Stops Sunburn, and More[…]
[…] A research team in Finland, led by Robin Ras, from Aalto University, and aided by researchers from the University of Jyväskylä, has developed a mechanism to make water droplets slip off surfaces with unprecedented efficacy. Cooking, transportation, optics and hundreds of other technologies are affected by how water sticks to surfaces or slides off Read more about Scientists create world’s most water-resistant surface[…]
A group of scientists studying the effects of rocket and satellite reentry vaporization in Earth’s atmosphere have found some startling evidence that could point to disastrous environmental effects on the horizon. The study, published in the Proceedings of the National Academy of Sciences, found that around 10 percent of large (>120 nm) sulfuric acid particles Read more about Spacecraft re-entry filling the atmosphere with metal vapor – and there will be more of it coming in[…]
[…]But these light sources [needed to experiment in the quantum realm] are not common. They’re expensive to build, require large amounts of land, and can be booked up by scientists months in advance. Now, a team of physicists posit that quasiparticles—groups of electrons that behave as if they were one particle—can be used as light Read more about Faster-Than-Light ‘Quasiparticles’ Touted as Futuristic Light Source[…]
The vaccine has been developed by the University of Oxford and is only the second malaria vaccine to be developed. Malaria kills mostly babies and infants, and has been one of the biggest scourges on humanity. There are already agreements in place to manufacture more than 100 million doses a year. It has taken more Read more about WHO Reccomends cheap malaria vaccine[…]
Climate breakdown is already changing the taste and quality of beer, scientists have warned. The quantity and quality of hops, a key ingredient in most beers, is being affected by global heating, according to a study.
