Phys.org / Storing memory on a chip with flowing water
Like the folds in crumpled sheets or the footprints on recently trodden sand, certain materials mark their histories. Now, Yale researchers show that networks of flowing water and other fluids can store their own memories—similar ...
Phys.org / Rocks from hydrothermal vents can spontaneously combust, posing potential risks for deep-sea mining operations
Projects involving the mining of seafloor massive sulfide (SMS) deposits around hydrothermal vents already face criticism over their destructive nature, and now these projects may face a new concern: spontaneous combustion. ...
Phys.org / 'Lost' Iron Age cemetery reanalyzed more than 70 years after its finds went missing
In 1955, workers in a chalk quarry in Highsted, near Sittingbourne, were working when a human skull came tumbling down the bank at the edge of a pit. It would be the first of some 26 burials, all belonging to an ancient cemetery.
Phys.org / Math under pressure may make a gamble's downside seem smaller
People who tackled arithmetic problems while stressed by a countdown clock, error buzzers and an observer nearby later gave potential losses less weight when deciding whether to accept a gamble. This finding from a new study ...
Phys.org / New evidence points to two feeding black holes just 175 parsecs apart lurking in the early universe
Astronomers have found two actively feeding supermassive black holes separated by just 175 parsecs (570 light-years) in a galaxy seen when the universe was only about 2 billion years old. The system, MG B2016+112, lies at ...
Phys.org / Toothless 'hell chicken' dinosaur may have had a taste for fruit
While many dinosaurs were fearsome predators with razor-sharp teeth, others were peaceful herbivores munching on plants. We can now add a new species to the list of plant-eaters, Infernogallus jamesi. Its name means hell ...
Phys.org / Quantum network test checks entanglement without having to trust detectors
Quantum networks are systems that connect different users or devices using principles of quantum mechanics. In the future, these networks could help improve the security of communications.
Phys.org / Your dog may link sounds with shapes, just like you do
Sounds have shapes. That might sound strange since sound waves are invisible, but a famous psychological experiment in the 1920s showed that our brains naturally link spoken sounds to visual forms. According to new research ...
Phys.org / New chip-scale gyroscope measures rotation with unprecedented sensitivity
Researchers have developed a chip-scale optical ring-laser gyroscope that can measure rotation as slow as 37 degrees per hour. This record sensitivity, approaching Earth's rotation rate of 15 degrees per hour, could eventually ...
Phys.org / Green, pink and purple: Astronomers reveal the surprising true colors of white dwarf stars
University of Warwick astronomers have shown that white dwarf stars can glow in a range of colors, including the first star ever found that would appear green to the human eye.
Phys.org / NASA develops batteries to power humanity's return to moon
If you've ever had your car start sluggishly, or not at all, on a particularly frigid winter morning, you know standard batteries do not like extreme cold. That's why NASA researchers are working to develop a battery that ...
Phys.org / How E. coli eavesdrops on the metabolic activity of other gut bacteria
The gut microbiome is teeming with hundreds of bacterial species and trillions of bacteria. These microorganisms influence many aspects of health, including digestion, and assist with numerous functions in the body. Gut bacteria ...
