Whiteness of AI erases people of color from our 'imagined futures', researchers argue

August 5, 2020byThe overwhelming 'Whiteness' of artificial intelligence—from stock images and cinematic robots to the dialects of virtual assistants—removes people of colour from the way humanity thinks about its technology-enhanced future.This is according to experts at the University of Cambridge, who suggest that current portrayals and stereotypes about AI risk creating a "racially homogenous" workforce of aspiring technologists, building machines with bias baked into their algorithms.They argue that cultural depictions of AI as White need to be challenged, as they do not offer a...

Calcium-rich supernova examined with X-rays for first time

Calcium-rich supernova examined with X-rays for first time

August 5, 2020by Amanda Morris,Half of all the calcium in the universe—including the very calcium in our teeth and bones—was created in the last gasp of dying stars.Called "-rich supernovae," these are so rare that astrophysicists have struggled to find and subsequently study them. The nature of these supernovae and their mechanism for creating calcium, therefore, have remained elusive.Now a Northwestern University-led team has potentially uncovered the true nature of these rare, mysterious events. For the first time ever, the researchers examined a calcium-rich supernova with X-ray...

Black hole fails to do its job

August 3, 2020byAstronomers have discovered what can happen when a giant black hole does not intervene in the life of a galaxy cluster. Using NASA's Chandra X-ray Observatory and other telescopes they have shown that passive black hole behavior may explain a remarkable torrent of star formation occurring in a distant cluster of galaxies.Galaxy clusters contain hundreds or thousands of galaxies pervaded by hot, X-ray emitting gas that outweighs the combined mass of all the galaxies. Ejections of material powered by a supermassive black hole in the cluster's central galaxy usually prevent...

Analyzing pros and cons of two composite manufacturing methods

Analyzing pros and cons of two composite manufacturing methods

July 31, 2020byAirplane wings, wind turbine blades, and other large parts are typically created using bulk polymerization in composite manufacturing facilities. They are heated and cured in enormous autoclaves and heated molds as big as the finished part. Frontal polymerization is a new out-of-autoclave method for composite manufacturing that doesn't require a large facility investment. Researchers at the University of Illinois at Urbana-Champaign conducted a study pitting one process against the other to discover the pros and cons of each."Frontal doesn't use an autoclave at all, so it...

Nano-sponges of solid acid transform carbon dioxide to fuel and plastic waste to chemicals

Nano-sponges of solid acid transform carbon dioxide to fuel and plastic waste to chemicals

July 31, 2020byThe primary cause of climate change is atmospheric CO2, and levels are rising every day. There is, therefore, a great need to find ways to reduce CO2 levels. On other hand, an excessive amount of plastic waste has become a serious environmental problem. In this work, published in Nature Communications, researchers dealt with both problems at one stroke, by developing nano solid acids that transform CO2 directly to fuel (dimethyl ether) and plastic waste to chemicals (hydrocarbons).Solid acids are among the most essential heterogeneous catalysts, which have the potential to...

Breakthrough method for predicting solar storms

Breakthrough method for predicting solar storms

July 29, 2020byExtensive power outages and satellite blackouts that affect air travel and the internet are some of the potential consequences of massive solar storms. These storms are believed to be caused by the release of enormous amounts of stored magnetic energy due to changes in the magnetic field of the sun's outer atmosphere—something that until now has eluded scientists' direct measurement. Researchers believe this recent discovery could lead to better "space weather" forecasts in the future."We are becoming increasingly dependent on space-based systems that are sensitive to space...
