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.

Astronomers spot a 'highly eccentric' planet on its way to becoming a hot Jupiter      (via sciencedaily.com)     Original source 

The newly discovered planet TIC 241249530 b has the most highly elliptical, or eccentric, orbit of any known planet. It appears to be a juvenile planet that is in the midst of becoming a hot Jupiter, and its orbit is providing some answers to how such large, scorching planets evolve.

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.

Bizarre 'garden sprinkler-like' jet is spotted shooting out of neutron star      (via sciencedaily.com)     Original source 

A strange 'garden sprinkler-like' jet coming from a neutron star has been pictured for the first time. The S-shaped structure is created as the jet changes direction due to the wobbling of the disc of hot gas around the star -- a process called precession, which has been observed with black holes but, until now, never with neutron stars.

Making rechargeable batteries more sustainable with fully recyclable components      (via sciencedaily.com)     Original source 

Rechargeable solid-state lithium batteries are an emerging technology that could someday power cell phones and laptops for days with a single charge. Offering significantly enhanced energy density, they are a safer alternative to the flammable lithium-ion batteries currently used in consumer electronics -- but they are not environmentally friendly. Current recycling methods focus on the limited recovery of metals contained within the cathodes, while everything else goes to waste.

NASA's Webb investigates eternal sunrises, sunsets on distant world      (via sciencedaily.com)     Original source 

Researchers using NASA's James Webb Space Telescope have finally confirmed what models have previously predicted: An exoplanet has differences between its eternal morning and eternal evening atmosphere. WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but similar mass to Saturn that orbits a star about 700 light-years away from Earth, is tidally locked to its parent star. This means it has a constant dayside and a constant nightside -- one side of the planet is always exposed to its star, while the other is always shrouded in darkness.

An international study reveals the extreme atmospheric conditions on the celestial objects, which are swathed in swirling clouds of hot sand amid temperatures of 950C. Using NASA's powerful James Webb Space Telescope (JWST), researchers set out to capture the weather on a pair of brown dwarfs -- cosmic bodies that are bigger than planets but smaller than stars.

Researchers announced the latest findings from the James Webb Space Telescope (JWST) of the supernova remnant, Cassiopeia A (Cas A). These observations of the youngest known core collapse supernova in the Milky Way provide insights into the conditions that lead to the formation and destruction of molecules and dust within supernova ejecta. The study's findings change our understanding of dust formation in the early universe in the galaxies detected by JWST 300 million years after the Big Bang.

Cosmic wrestling match      (via sciencedaily.com)     Original source 

Our universe is around 13.8 billion years old. Over the vastness of this time, the tiniest of initial asymmetries have grown into the large-scale structures we can see through our telescopes in the night sky: galaxies like our own Milky Way, clusters of galaxies, and even larger aggregations of matter or filaments of gas and dust. How quickly this growth takes place depends, at least in today's universe, on a sort of wrestling match between natural forces: Can dark matter, which holds everything together through its gravity and attracts additional matter, hold its own against dark energy, which pushes the universe ever further apart?

A chemical claw machine bends and stretches when exposed to vapors      (via sciencedaily.com)     Original source 

Scientists have developed a tiny 'claw machine' that is able to pick up and drop a marble-sized ball in response to exposure to chemical vapors. The findings point to a technique that can enable soft actuators--the parts of a machine that make it move--to perform multiple tasks without the need for additional costly materials. While existing soft actuators can be 'one-trick ponies' restricted to one type of movement, this novel composite film contorts itself in different ways depending on the vapor that it is exposed to.
