Tech Xplore / Human understanding of AI can't keep up with its advancement, researchers say
In a recent editorial published in Science, Microsoft's chief scientific officer, Eric Horvitz, and researcher Robert West from the School of Computer and Communication Sciences at EPFL in Switzerland issue a stark warning ...
Phys.org / Human evolution was messy and gradual, not an abrupt revolution, argues archaeologist
It is generally accepted by archaeologists that modern humans originated in Africa and dispersed worldwide, while other hominins went extinct. Yet how and when Homo sapiens dispersed out of Africa, and whether it was an abrupt ...
Phys.org / Maya altar and offerings at abandoned Belize sites highlight enduring ritual activities
Archaeologists excavating Maya sites at Kaxil Uinik and Ayiin Winik in Belize have discovered the first reported Late Postclassic altar in the region, along with additional evidence that Postclassic Maya people continued ...
Phys.org / Newfound sound wave scattering rule may lead to less bulky, more effective soundproofing
Researchers in China recently uncovered a quantum-inspired rule governing how sound is scattered by certain physical properties of a material. Their research, published in Physical Review Letters, may lead to the ability ...
Phys.org / Atlantic 'cold blob' caused by weakening ocean current system that's likely nearing a tipping point, reanalysis finds
A part of the Atlantic Ocean, just south of Greenland and Iceland, has been cooling off while the rest of the world gets hotter. This enigmatic patch is often referred to as the "cold blob" and scientists have been trying ...
Phys.org / Costa Rica paid landowners to restore forests and biodiversity—bioacoustics indicate that it worked
Forest restoration can help fight climate change and restore lost biodiversity, but the satellite-based techniques used to measure successful forest restoration have been less-than-helpful for measuring changes in biodiversity. ...
Phys.org / Deep-Earth seismic anomalies may be explained by newly discovered manganese compound
Scientists know that manganese, in its various oxide forms, plays a significant role in Earth's geochemical cycles. However, the exact forms of manganese, their abundance and the mechanisms behind these cycles that occur ...
Phys.org / Plate tectonics shaped the Cradle of Civilization by merging two ancient rivers, study suggests
The Euphrates River is the longest river in Western Asia and runs through the eastern side of the Fertile Crescent. Flowing over 1,700 miles from Turkey through Syria and Iraq, the river played a crucial role in sustaining ...
Phys.org / Mathematician solves origami donut efficiency challenge with fewest folds
Most people wouldn't think that it would take rigorous mathematical proof to show how many folds it takes to make a donut shape out of paper. Yet, no one could quite figure it out until recently.
Phys.org / Mars's manganese 'bathtub ring' reveals ancient ocean timeline and its potential for life
Past research has indicated Mars's largest northern basin, Utopia Planitia, was once the location of a large body of water, but details surrounding when this body of water may have existed have not been resolved. Researchers ...
Phys.org / Quantum pendulum clock overcomes classical accuracy limits and sheds light on quantum to classical transitions
In a grandfather clock, a pendulum swings back and forth and this periodic motion is maintained using the energy stored in its suspended weights. This is done with the help of the escapement mechanism, which converts the ...
Phys.org / Earth's oxygen-rich atmosphere may owe its existence to cold subduction
Earth was mostly devoid of oxygen for much of its 4.5 billion year lifetime. That is, until certain processes started to allow for the eventual buildup of oxygen up to the levels we have now (around 21% of the atmosphere). ...
Phys.org / Polymer strategy boosts lithium battery safety and performance by making plasticizers compatible
The performance and safety profile of lithium batteries has improved immensely over the years, but new technologies are constantly demanding even better performance and increased safety demands due to higher energy densities. ...
Phys.org / Mercury's water ice may have been deposited by a larger, slower impactor than previously thought—in only one day
The source of the significant water ice deposits hidden in Mercury's polar regions has been a topic of debate among researchers. A new study, published in the Journal of Geophysical Research: Planets, suggests that these ...
Phys.org / Mathematicians solve decades-old mystery about the hidden order in high-dimensional randomness
Three mathematicians have laid out proof that solves a long-standing problem in mathematics. Even the mathematician—an Abel prize winner—that first posed the problem didn't believe it would ever be solved. The solution provides ...
