Phys.org / A new, useful absorption limit for ultra-thin films
Ultrathin, conductive films such as those made of graphene are widely used in modern optoelectronic devices, but it has been thought that their efficacy is fundamentally limited: they can absorb at most half of the incident ...
Phys.org / A new 'uncertainty relation' for quantum measurement errors
One of the most striking features of quantum physics is that certain properties cannot both be known or measured with arbitrary precision at the same time. Every measurement may inevitably affect the object's physical state ...
Phys.org / 'Mismatched' plant water isotopes vanish with better sampling: Study points to better drought forecasts
For decades, scientists have relied on a chemical fingerprint inside water molecules to determine where plants get their moisture. The method shaped our understanding of drought resilience, groundwater use, and ecosystem ...
Phys.org / Six years of field data show how climate and light shape early growth of abarco, informing reforestation in Colombia
A new study shows how climate and light conditions interaction affect the early growth in abarco, a highly valued tropical timber species, offering critical guidance for reforestation and sustainable forest management in ...
Phys.org / Researchers decode the welfare effects of pricing algorithms
The National Bureau of Economic Research has published a new working paper by economists Ali Shourideh (Carnegie Mellon University, Tepper School of Business), Maryam Farboodi (Massachusetts Institute of Technology), and ...
Medical Xpress / Councils in the UK face industry legal threats for campaigns warning against wood-burning stoves
As the UK government considers adding health warnings to new wood-burning stoves, as part of a public consultation on solid fuel burning, councils in England are being threatened with legal action for running public health ...
Phys.org / Study shows COVID-19 financial stress slowed digital finance adoption in Africa
The COVID-19 pandemic accelerated the use of financial technology worldwide, including in many African countries, but it also brought financial hardships, leading to negative impacts on digital financial inclusion. In a new ...
Phys.org / Self-propelling microbes switch up swimming strategy to optimize light intake
Researchers in Hong Kong and the UK have revealed how one species of self-propelling microbes can actively change the path of their swimming motions, depending on how much light they receive. Reporting in Physical Review ...
Phys.org / Chemically 'stapled' peptides used to target difficult-to-treat cancers
Researchers at the University of Bath have developed a new technology that uses bacteria to build, chemically stabilize, and test millions of potential drug molecules inside living cells, making it much quicker and easier ...
Phys.org / Deadly soil fungal pathogen puts Australia's reptiles at risk of extinction
University of Queensland researchers say Australia's reptiles are at risk of extinction because a little understood fungus is infecting species throughout the environment. Associate Professor Celine Frere from UQ's School ...
Tech Xplore / Deepfakes, job losses, opaque models: Exploring the dark side of AI
Artificial intelligence (AI) has become one of the defining technologies of what economists and policymakers describe as the Fourth Industrial Revolution. This is an era in which digital, physical, and biological systems ...
Phys.org / Rising carbon dioxide levels now detected in human blood
Rising carbon dioxide levels are being detected within the human body, with new research warning a key blood marker for the gas could near its healthy limit within decades if current trends continue. The findings are especially ...
