Tech Xplore / Artificial metacognition: Giving an AI the ability to 'think' about its 'thinking'
Have you ever had the experience of rereading a sentence multiple times only to realize you still don't understand it? As taught to scores of incoming college freshmen, when you realize you're spinning your wheels, it's time ...
Phys.org / Moon-based observations capture Earth's 'radiation fingerprint'
Earth's radiation budget is a core process of the Earth-atmosphere system, closely linked to global climate and environmental changes. While current satellite observations have greatly advanced our understanding of Earth's ...
Phys.org / Scientists may have solved 66 million-year-old mystery of how Earth's greenhouse age ended
A 66 million-year-old mystery behind how our planet transformed from a tropical greenhouse to the ice-capped world of today has been unraveled by scientists. Their new study has revealed that Earth's massive drop in temperature ...
Phys.org / Proposed new mission will create artificial solar eclipses in space
When a solar storm strikes Earth, it can disrupt technology that's vital for our daily lives. Solar storms occur when magnetic fields and electrically charged particles collide with Earth's magnetic field. This type of event ...
Phys.org / Scientists may have discovered a new extinct form of life
Prototaxites are something of a prehistoric mystery. They were the first giant organisms on land, towering over ancient landscapes at heights of up to 8 meters. They had smooth trunk-like pillars and no branches, leaves or ...
Phys.org / Great power rivalry is reshaping global supply chains, new study shows
Rising tensions between the US and China are changing how companies design global supply chains in strategic industries such as semiconductors and rare earths. New research shows firms are no longer just reacting to trade ...
Phys.org / Citizen science and the challenge of measuring urban sustainability
Cities are expected to track sustainability progress with data that are often incomplete, outdated, or available only at national level. New research led by IIASA in collaboration with UN-Habitat finds that citizen science ...
Medical Xpress / A fish that grows old in months reveals how kidneys age—and how a common drug protects them
In a new study published in Kidney International, researchers report that drugs known as SGLT2 inhibitors prevented age-related deterioration of kidney structure and function in the African turquoise killifish, a vertebrate ...
Phys.org / Journey to center of Milky Way with upcoming NASA Roman core survey
At the heart of our own galaxy, there is a dense thicket of stars with a supermassive black hole at the very center. NASA's Nancy Grace Roman Space Telescope will provide the deepest-ever view of this zone, revealing stars, ...
Phys.org / Particle permutation task can be tackled by quantum but not classical computers, study finds
Quantum computers, systems that process information leveraging quantum mechanical effects, are expected to outperform classical computers on some complex tasks. Over the past few decades, many physicists and quantum engineers ...
Phys.org / Novel biosensor enables real-time tracking of iron (II) in living cells
Iron is an essential trace element in biological cells. The concentration of the element and its so-called redox state—it can exist either in a doubly ionized state as iron (II) (Fe2+) or a triply ionized state as iron ...
Phys.org / Most men do not subscribe to toxic masculinity traits, study finds
A growing niche space, the manosphere, has been taking shape in today's online forums and social media, preaching an aggressive definition of what it means to be a man. It promotes traits such as misogyny, dominance, and ...
