Scientists discover hidden oasis of life underneath world’s driest desert
Posted by Genevieve Klien in categories: biological, habitats, space, sustainability
POTSDAM, Germany — One of the most lifeless places on Earth is actually hiding an underground biosphere teeming with microscopic life! Researchers have unearthed this amazing oasis under Chile’s Atacama Desert. The findings not only change our view of life on Earth, but they might prove that there is still life under the soil of dead alien worlds like Mars!
Despite being renowned as the driest desert on Earth, with some regions going decades or even centuries without a drop of rain, researchers from Germany discovered hardy communities of microorganisms that have managed to carve out habitats deep below the desert floor. Down here, totally isolated from the surface world, microscopic life finds a way to eke out an existence against all odds.
Study author Dirk Wagner and the team from the GFZ German Research Centre for Geosciences explain that they detected signs of potentially viable microbial ecosystems as far as 13 feet underground. This remarkable discovery is upending our understanding of desert biodiversity, demonstrating that life can persist in even the most extreme subterranean environments on Earth.

How light can vaporize water without the need for heat
Posted by Saúl Morales Rodriguéz in category: futurism
It’s the most fundamental of processes—the evaporation of water from the surfaces of oceans and lakes, the burning off of fog in the morning sun, and the drying of briny ponds that leaves solid salt behind. Evaporation is all around us, and humans have been observing it and making use of it for as long as we have existed.
And yet, it turns out, we’ve been missing a major part of the picture all along.
In a series of painstakingly precise experiments, a team of researchers at MIT has demonstrated that heat isn’t alone in causing water to evaporate. Light, striking the water’s surface where air and water meet, can break water molecules away and float them into the air, causing evaporation in the absence of any source of heat.

The big quantum chill: Scientists modify common lab refrigerator to cool faster with less energy
Posted by Saúl Morales Rodriguéz in categories: energy, quantum physics
By modifying a refrigerator commonly used in both research and industry, researchers at the National Institute of Standards and Technology (NIST) have drastically reduced the time and energy required to cool materials to within a few degrees above absolute zero.

Record electron temperatures for a small-scale, sheared-flow-stabilized Z-pinch fusion device achieved
Posted by Saúl Morales Rodriguéz in category: nuclear energy
In the nine decades since humans first produced fusion reactions, only a few fusion technologies have demonstrated the ability to make a thermal fusion plasma with electron temperatures hotter than 10 million degrees Celsius, roughly the temperature of the core of the sun. Zap Energy’s unique approach, known as a sheared-flow-stabilized Z pinch, has now joined those rarefied ranks, far exceeding this plasma temperature milestone in a device that is a fraction of the scale of other fusion systems.

Novel method could explore gluon saturation at the future electron-ion collider
Posted by Saúl Morales Rodriguéz in categories: futurism, particle physics
The U.S. nuclear physics community is preparing to build the electron–ion collider (EIC), a flagship facility for probing the properties of matter and the strong nuclear force that holds matter together. The EIC will allow scientists to study how nucleons (protons and neutrons) arise from the complex interactions of quarks and gluons.

Oxford shuts down institute run by Elon Musk-backed philosopher
Posted by Nicholi Avery in category: Elon Musk
Meanwhile, Bostrom’s email from the 1990s resurfaced last year and resulted in him issuing a statement repudiating his racist remarks and clarifying his views on subjects such as eugenics. Some of his answers – “Do I support eugenics? No, not as the term is commonly understood” – led to further criticism from fellow academics that he was being evasive.
The university launched an investigation into Bostrom’s conduct following the discovery of his racist email, while other major effective altruism groups distanced themselves from him.
“We unequivocally condemn Nick Bostrom’s recklessly flawed and reprehensible words,” the Centre for Effective Altruism, which was founded by fellow Oxford philosophers and financially backed by Bankman-Fried, said in a statement at the time.
