Potent greenhouse gas produced by industry could be readily abated with existing technologies: Affordable and available technologies can curb rising nitrous oxide emissions

Researchers have found that one method of reducing greenhouse gas emissions is available, affordable, and capable of being implemented right now. Nitrous oxide, a potent greenhouse gas and ozone-depleting substance, could be readily abated with existing technology applied to industrial sources. “The urgency of climate change requires that all greenhouse…

Growing bio-inspired polymer brains for artificial neural networks

A new method for connecting neurons in neuromorphic wetware has been developed by researchers from Osaka University and Hokkaido University. The wetware comprises conductive polymer wires grown in a three-dimensional configuration, done by applying square-wave voltage to electrodes submerged in a precursor solution. The voltage can modify wire conductance, allowing…

Fast, automated, affordable test for cement durability

Engineers at the University of Illinois Urbana-Champaign have developed a new test that can predict the durability of cement in seconds to minutes — rather than the hours it takes using current methods. The test measures the behavior of water droplets on cement surfaces using computer vision on a device…

Cell phones to be banned from Dutch school classrooms next year | CNN

Reuters  —  Cell phones, tablets and smartwatches will be largely banned from classrooms in the Netherlands from January 1, 2024, the Dutch government said on Tuesday, in a bid to limit distractions during lessons. Devices will only be allowed if they are specifically needed, for instance during lessons on digital…

Live updates: Russia’s war in Ukraine

Ukrainian forces have “proceeded in a very precise and well-organized way so far” in the war, German Chancellor Olaf Scholz said Tuesday. Speaking at a joint news conference with Romanian Prime Minister Marcel Ciolacu, Scholz said he “never expected that everything would change from one day to the next,” but…

Prominent Russian journalist ‘severely beaten’ in attack in Chechnya | CNN

CNN  —  Elena Milashina, a prominent Russian journalist who uncovered the horrific crackdown on gay men in Chechnya, was severely beaten alongside a lawyer in an attack in the southern Russian republic, according to her employer Novaya Gazeta. Milashina and attorney Alexander Nemov were on the way to attend a…

World’s most threatened seabirds visit remote plastic pollution hotspots

The extensive study assessed the movements of 7,137 individual birds from 77 species of petrel, a group of wide-ranging migratory seabirds including the Northern Fulmar and European Storm-petrel, and the Critically Endangered Newell’s Shearwater. This is the first time that tracking data for so many seabird species has been combined…

Fewer teens now perceive themselves as overweight — international study of more than 745,000 adolescents: Changes in body weight perception could undermine public health interventions to tackle obesity

A study involving more than 745,000 adolescents from 41 countries across Europe and North America identified an increase in the amount of teenagers who underestimate their body weight. Tracking data from 2002 to 2018, the peer-reviewed findings, published today in Child and Adolescent Obesity, demonstrate a noticeable decrease in those…

‘Workplace AI revolution isn’t happening yet,’ survey shows

The UK risks a growing divide between organisations who have invested in new, artificial intelligence-enabled digital technologies and those who haven’t, new research suggests. Only 36% of UK employers have invested in AI-enabled technologies like industrial robots, chat bots, smart assistants and cloud computing over the past five years, according…

How the ear can inform the brain of whether hearing is impaired

A cochlear signal, the exact role of which has been unclear since its discovery around 70 years ago, probably gives the brain information on whether the ear is functioning normally or not. This is the conclusion of a study from Linköping University, Sweden. Its findings are an important piece of…

How mercury emissions from industry can be greatly reduced

Sulphuric acid is the world’s most used chemical. It is an important reagent used in many industries and it is used in the manufacture of everything from paper, pharmaceuticals and cosmetics to batteries, detergents and fertilisers. It is therefore a worldwide challenge that sulphuric acid often contains one of the…

Three things to know: Climate change’s impact on extreme-weather events

In an article published in the Proceedings of the National Academy of Sciences, Michael Mann, professor in the Department of Earth and Environmental Science in the University of Pennsylvania’s School of Arts & Sciences, and colleagues from Clemson University, the University of California Los Angeles, and Columbia University investigate the…

Chemists discover why photosynthetic light-harvesting is so efficient: The disorganized arrangement of the proteins in light-harvesting complexes is the key to their extreme efficiency

When photosynthetic cells absorb light from the sun, packets of energy called photons leap between a series of light-harvesting proteins until they reach the photosynthetic reaction center. There, cells convert the energy into electrons, which eventually power the production of sugar molecules. This transfer of energy through the light-harvesting complex…

Planting seeds: Researchers dig into how chemical gardens grow

Since the mid-1600s, chemists have been fascinated with brightly colored, coral-like structures that form by mixing metal salts in a small bottle. Until now, researchers have been unable to model how these deceptively simple tubular structures — called chemical gardens — work and the patterns and rules that govern their…

Inadequate energy intake affects female athletes

A new study from Aarhus University shows that when female athletes lower their energy intake and increase their training, their health and the ability of their muscles to respond to training are negatively impacted. Diet and training go hand in hand if you want to achieve the best results. Most…
