Astrophysicists uncover supermassive blackhole/dark matter connection in solving the 'final parsec problem'      (via sciencedaily.com)     Original source 

Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles. Their new calculations reveal that pairs of supermassive black holes (SMBHs) can merge into a single larger black hole because of previously overlooked behavior of dark matter particles, proposing a solution to the longstanding 'final parsec problem' in astronomy.

Life signs could survive near surfaces of Enceladus and Europa      (via sciencedaily.com)     Original source 

Europa and Enceladus, icy moons of Jupiter and Saturn respectively, have evidence of oceans beneath their crusts. A NASA experiment suggests -- if these oceans support life -- signatures of that life in the form of organic molecules (like amino acids and nucleic acids) could survive just under the surface ice despite the harsh, ionizing radiation on these worlds. If robotic landers were to go to these moons to look for life signs, they would not have to dig very deep to find amino acids that have survived being altered or destroyed by radiation.

Want to spot a deepfake? Look for the stars in their eyes      (via sciencedaily.com)     Original source 

In an era when the creation of artificial intelligence (AI) images is at the fingertips of the masses, the ability to detect fake pictures -- particularly deepfakes of people -- is becoming increasingly important. So what if you could tell just by looking into someone's eyes? That's the compelling finding of new research which suggests that AI-generated fakes can be spotted by analyzing human eyes in the same way that astronomers study pictures of galaxies.

Physicists develop new theory describing the energy landscape formed when quantum particles gather together      (via sciencedaily.com)     Original source 

An international team of physicists has proven new theorems in quantum mechanics that describe the 'energy landscapes' of collections of quantum particles. Their work addresses decades-old questions, opening up new routes to make computer simulation of materials much more accurate. This, in turn, may help scientists design a suite of materials that could revolutionize green technologies.

How astronomers are using pulsars to observe evidence of dark matter      (via sciencedaily.com)     Original source 

Tantalizing evidence of potential dark matter objects has been detected with the help of the Universe's 'timekeepers'. These pulsars -- neutron stars which rotate and emit lighthouse-like beams of radio waves that rapidly sweep through space -- were used to identify mysterious hidden masses. Pulsars earned their nickname because they send out electromagnetic radiation at very regular intervals, ranging from milliseconds to seconds, making them extremely accurate timekeepers.

Capturing carbon with energy-efficient sodium carbonate-nanocarbon hybrid material      (via sciencedaily.com)     Original source 

Carbon capture is a promising approach for mitigating carbon dioxide (CO2) emissions. Different materials have been used to capture CO2 from industrial exhaust gases. Scientists developed hybrid CO2 capture materials containing sodium carbonate and nanocarbon prepared at different temperatures, tested their performance, and identified the optimal calcination temperature condition. They found that the hybrid material exhibits and maintains high CO2 capture capacity for multiple regeneration cycles at a lower temperature, making it cost- and energy-effective.
