Phys.org / To reach net-zero, reverse current policy and protect the largest trees in the Amazon, say scientists
At the United Nations Climate Change Conference in 2015, countries around the world committed to striving towards net-zero greenhouse gas emissions by the middle of the 21st century. But achieving this goal is difficult, ...
Phys.org / Breakthrough laser technique holds quantum matter in stable packets
For the first time, physicists have generated and observed stable bright matter-wave solitons with attractive interactions within a grid of laser light.
Phys.org / South African San rock art reveals trance dances and initiation ceremonies
In a study published in Telestes, Dr. Joshua Kumbani and Dr. Margarita Díaz-Andreu categorized the various dance scenes depicted in South African rock art, drawing on ethnographic sources, published studies, and the comprehensive ...
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 / 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 / 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 / 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 / Cleaner air is (inadvertently) harming the Great Barrier Reef
Air pollution is now recognized as one of the greatest threats to human health, contributing to an estimated 4.2 million premature deaths in 2019, according to the World Health Organization.
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 ...
