Medical Xpress / Neural dynamics shed light on how the brain adapts to and suppresses fearful memories
Over the course of their lives, humans can sometimes acquire fear responses to specific stimuli, animals, objects or situations, typically following adverse experiences or traumatic events. Understanding the brain processes ...
Phys.org / DNA from rainwater provides a window into tropical canopy biodiversity
Tropical rainforests still represent a treasure trove of undiscovered species. While many species of plants, animals, and insects have been identified over the years, some parts of these tropical ecosystems are difficult ...
Tech Xplore / Adding biochar to cement yields concrete that's stronger, more environmentally friendly
In Canada, it can seem like there are two seasons: winter and construction. Whether it's repairing sidewalks and streets, or building new homes and apartments, much of this work uses cement—the key ingredient of concrete.
Phys.org / New model describes result of non-reciprocal interactions between two non-linear molecules
Asymmetric interactions between different species of molecules have previously been demonstrated to result in self-organized patterns and functions. If one species A is attracted to B, but in turn, B is repelled by A, run-and-chase ...
Phys.org / Earth system models project start of Amazon dieback within 21st century
The Amazon is the world's largest rainforest. It harbors immense biodiversity and plays a crucial role in the global climate system by storing vast amounts of carbon in its vegetation.
Phys.org / Great white sharks head north, following seals and alarming beachgoers
Rick Clough spent some four decades fishing for lobsters and sea urchins off the Maine coast before spotting one of the ocean's most recognized predators—a great white shark.
Tech Xplore / Contrastive learning framework can detect blockchain-based smart Ponzi schemes
Blockchain technologies are digital systems that work by distributing copies of information across several computers, also referred to as nodes, all of which are connected to a common network. These technologies underpin ...
Phys.org / Measuring a previously mysterious imaginary component of wave scattering
There has long been a mystery when calculating how an incoming light wave scatters off an object and becomes a modified, outgoing light wave. In particular, the time delay of the transition from one to the other comes out ...
Phys.org / DNA from extinct hominin may have helped ancient peoples survive in the Americas
Thousands of years ago, ancient humans undertook a treacherous journey, crossing hundreds of miles of ice over the Bering Strait to the unknown world of the Americas.
Phys.org / Single quantum device that measures amperes, volts and ohms could revolutionize how we measure electricity
A team of scientists has revealed how a single quantum device can accurately measure the three fundamental units of electricity—the ampere (unit of electrical current), the volt (unit of electrical potential) and the ohm ...
Phys.org / Synthesis of a molecule found in guava plants offers hope in fighting liver-related cancers
You may not be aware that most of the medicines that have been approved for treatment are rooted in nature. For example, the bark of willow trees has been called nature's aspirin because it contains a chemical called salicin. ...
Medical Xpress / Open-label Phase II trial reports early motor milestones with risdiplam
From Johns Hopkins University School of Medicine, Charlotte J. Sumner, M.D., presents an editorial on a study by Richard S. Finkel and colleagues, who report an open-label, Phase II trial of the pre-messenger RNA splicing ...
