Phys.org / Superconducting nanowire memory array achieves significantly lower error rate
Quantum computers, systems that process information leveraging quantum mechanical effects, will require faster and energy-efficient memory components, which will allow them to perform well on complex tasks. Superconducting ...
Phys.org / A new look at trends in human deaths due to climate extremes
A new study of climate extremes since 1988 finds that many regions have seen increases in deaths due to floods, storms and extreme temperatures. In human terms, the harm comes not just from deaths, but also from lost labor ...
Phys.org / Bacteria use wrapping flagella to tunnel through microscopic passages, research reveals
Researchers have discovered how bacteria break through spaces barely larger than themselves, by wrapping their flagella around their bodies and moving forward. Using a microfluidic device that mimics insect gut channels, ...
Phys.org / Innovative catalyst enables CO₂-free production of hydrogen and formate from waste byproduct glycerol
Researchers at Johannes Gutenberg University Mainz (JGU) have developed a method that gives access to the valuable raw materials formate and hydrogen from the waste product glycerol. Formates are the salts of formic acid ...
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 / Ancient Spanish trees reveal Mediterranean storms are intensifying
Ancient pine trees growing in the Iberian mountains of eastern Spain have quietly recorded more than five centuries of Mediterranean weather. Now, by reading the annual growth rings preserved in their wood, scientists have ...
Phys.org / A new three-way single step rearrangement enables precise ring editing
A new three-way bond-breaking and making mechanism makes the synthesis of five-membered rings easier than before.
Phys.org / Edison's 1879 bulb experiments may have unintentionally produced graphene
What do Thomas Edison and 2010 Nobel Prize in physics winners Konstantin Novoselov and Andre Geim have in common? According to a recent publication from the lab of Rice University's James Tour in ACS Nano, it could be graphene—an ...
Phys.org / A year after undermining Bredt's rule, scientists make cage-shaped, double-bonded molecules that defy expectations
Organic chemistry is packed with rules about structure and reactivity, especially when it comes to making and breaking chemical bonds. The rules governing how these bonds, which hold atoms together in molecules, form and ...
Phys.org / Saturday Citations: A weird, extinct life form; cholesterol hacking; interspecies prosociality of whales
It's Saturday! This week, in an eminently practical analysis of the Boltzmann brain conjecture, physicists put constraints on the idea that memories could arise from random fluctuations in entropy rather than reflecting the ...
Dialog / Using amino acids as fuels to make conductive graphene
Graphene has drawn attention as a scientific curiosity owing to its record conductivities, strength and thermal properties. But now, it's starting to make its way into a number of real-world applications, from batteries to ...
Phys.org / Rats demonstrate ability to replay episodic memories in complex experimental settings
In a new study Indiana University researchers observed episodic memory in rats to a degree never documented before, suggesting that rats can serve as a model for complex cognitive processes often considered exclusively human. ...
