In a 'seismological wind tunnel,' engineers demonstrate the impact of rock gouge -- ground-up rock along a fault boundary -- on earthquake propogation.
Scientists have revealed the effect of temperature on water in protein-ligand interactions, providing a way to produce structures for drug discovery that are less biased by freezing artifacts.
What's the relationship between people's perception of beauty and animals' conservation needs? According to a machine-learning study, the reef fishes that people find most beautiful tend to be the lowest priority for conservation support.
Current technologies to modulate light in free space are bulky, slow, static, or inefficient. Now researchers have developed a compact and tunable electro-optic modulator for free space applications that can modulate light at gigahertz speed.
Researchers found that administration of the drug rapamycin in mice was associated with increased beta-amyloid plaques. This is one of the hallmark pathologies of Alzheimer's disease. The study authors caution that rapamycin's effects in beta-amyloid-associated Alzheimer's must be studied more carefully.
Owing to their unique permeable, hollow shell structures with inner, movable cores, yolk-shell nanocrystals are suitable for a wide variety of applications. Yolk-shell nanocrystals consisting of a gold core with various semiconductor shells have been developed using a novel sequential ion-exchange process. These metal-semiconductor yolk-shell nanocrystals can serve as highly effective...
A new theory of economic decision-making offers an explanation as to why humans, in general, make decisions that are simply adequate, not optimal.
New research shows pressure from manufacturers and suppliers of opioids, particularly national corporations, influenced how pharmacies bought and distributed those prescriptions.
As people across the globe look forward to longer life expectancies, malignant cancers continue to pose threats to human health. The exploration and development of immunotherapy aims to seek new breakthroughs for the treatment of solid tumors. Although immune checkpoint-based immunotherapy has been shown to have great potential, only a small proportion of patients fully respond to this therapy,...
Researchers succeed in increasing the prediction accuracy of the battery capacity by up to 20% by merging physical domain knowledge with AI.
More areas of year-round unfrozen ground have begun dotting Interior and Northwest Alaska and will continue to increase in extent due to climate change, according to new research.
Researchers describe a new way to evaluate rankings. Their goal is not to find one true hierarchy, but to calculate the spread of all possible hierarchies, with each one weighted by its probability.
Researchers have developed a tiny sensor for detecting pesticides on fruit in just a few minutes. The technique uses flame-sprayed nanoparticles made from silver to increase the signal of chemicals. While still at an early stage, the researchers hope these nano-sensors could help uncover food pesticides before consumption.
Micronutrient deficiencies can promote inflammation and render the immune system particularly sensitive to allergenic substances. In particular, iron deficiency signals danger to immune cells and leads to a more pronounced, exaggerated immune response. For the first time, scientists have conducted a placebo-controlled trial and showed that targeted dietary measures can reduce the symptom burden in...
Initiatives using non-native tree species can impact tropical insects in neighbouring forests, according to an international study.
The numerous casualties of bats at wind turbines (WT) have a negative impact on the populations of affected species and potentially far-reaching consequences for the biodiversity in rural areas. Until now, it could only be assumed that the death of bats had further consequences. Now, a team of scientists show that natural food chains are interrupted, which can have far-reaching negative...
A study reveals new details about how ketamine works, paving the way toward the development of safe, effective treatments for depression.
A new synthesis method offers hope for creation of advance mRNA vaccines to fight viruses and even cancers.
A team of physicists has found a way to operate mass manufacturable photonic sensors at the quantum limit. This breakthrough paves the way for practical applications such as monitoring greenhouse gases and cancer detection.
Researchers have demonstrated a link between diet, circadian rhythms, eye health and lifespan in Drosophila. They additionally and unexpectedly found that processes in the fly eye are actually driving the aging process.
New findings highlight clear differences in grey matter for people with anorexia nervosa and point to the importance of early treatment interventions.
Researchers have improved the coherence time of a previously developed quantum membrane dramatically. The improvement will expand the usability of the membrane for a variety of different purposes. With a coherence time of one hundred milliseconds, the membrane can for example store sensitive quantum information for further processing in a quantum computer or network.
Scientists have characterized the genetic factors that affect the immune response in type 1 diabetes patients, with potential implications for developing new treatments.
The emergence of a mysterious area in the South Atlantic where the geomagnetic field strength is decreasing rapidly, has led to speculation that Earth is heading towards a magnetic polarity reversal. However, a new study that pieces together evidence stretching back 9,000 years, suggests that the current changes aren't unique, and that a reversal may not be in the cards after all.
