CLEMSON, South Carolina - Clemson University scientists have taken another step forward in their quest to find a cure for a notorious parasite that has infected more than 40 million Americans and many times that number around the world.
A new way of creating carbon fibers -- which are typically expensive to make -- could one day lead to using these lightweight, high-strength materials to improve safety and reduce the cost of producing cars, according to a team of researchers. Using a mix of computer simulations and laboratory experiments, the team found that adding small amounts of the 2D graphene to the production process both reduces the production cost and strengthens the fibers.
HOUSTON -- (May 18, 2020) -- U.S. and German physicists have found surprising evidence that one of the most famous phenomena in modern physics -- the quantum Hall effect -- is "reincarnated" in topological superconductors that could be used to build fault-tolerant quantum computers.
TODAY'S young people can be dubbed the "Coronavirus Generation" and the pandemic will have a long-lasting effect on their lives, according to a University of Huddersfield lecturer who has helped analyse the data from a research project that aimed to appraise the impact of the virus on UK youth.
Findings include statistics which show that more than 90 per cent of young people were stringently observing the lockdown and that 80 per cent of them are seeking news not from social media but from traditional outlets, including ministerial briefings.
It sounds like a riddle: What do you get if you take two small diamonds, put a small magnetic crystal between them and squeeze them together very slowly?
The emergence of new means of communication via the Internet has brought about new genres of discourse, understood as socially situated communication practices that did not previously exist, and which require studying from the linguistic standpoint.
Forty years after the description of the 'oral-written' medium proposed by Gregory and Carroll (1978) and in the light of some recent studies, these experts consider the WhatApp message genre as a "fuzzy category", a genre that, though initially written, does not have a clear separating line between speaking and writing.
Imagine biting into a peanut butter sandwich and discovering a slice of cheese tucked between the bread and the butter. In a way, this is what happened to a team of physicists at the University of Arizona, except the "cheese" was a layer of iron oxide, less than one atomic layer thick, and the "sandwich" was a magnetic tunnel junction - a tiny, layered structure of exotic materials that someday may replace current silicon-based computer transistors and revolutionize computing.
Semiconductor companies are struggling to develop devices that are mere nanometers in size, and much of the challenge lies in being able to more accurately describe the underlying physics at that nano-scale. But a new computational approach that has been in the works for a decade could break down these barriers.
Tantalum disulfide is a mysterious material. According to textbook theory, it should be a conducting metal, but in the real world it acts like an insulator. Using a scanning tunneling microscope, researchers from the RIKEN Center for Emergent Matter Science have taken a high-resolution look at the structure of the material, revealing why it demonstrates this unintuitive behavior.
DURHAM, N.C. -- A Duke University research team has found a small area of the brain in mice that can profoundly control the animals' sense of pain.
Somewhat unexpectedly, this brain center turns pain off, not on. It's also located in an area where few people would have thought to look for an anti-pain center, the amygdala, which is often considered the home of negative emotions and responses, like the fight or flight response and general anxiety.
New and diverse experiences are linked to enhanced happiness, and this relationship is associated with greater correlation of brain activity, new research has found. The results, which appear in the journal Nature Neuroscience, reveal a previously unknown connection between our daily physical environments and our sense of well-being.
Novel quantum dot solar cells developed at Los Alamos National Laboratory match the efficiency of existing quantum-dot based devices, but without lead or other toxic elements that most solar cells of this type rely on.
"This quantum-dot approach shows great promise for a new type of toxic-element-free, inexpensive solar cells that exhibit remarkable defect tolerance," said Victor Klimov, a physicist specializing in semiconductor nanocrystals at Los Alamos and lead author of the report featured on the cover of the journal Nature Energy.
A new study reveals clear evidence highlighting the importance of fish biodiversity to the health of spectacular tropical coral reef ecosystems.
This is the case for reefs that are pristine and also those that have been affected by stresses, such as bleaching events caused by warming oceans.
However, the study's results show that even though strong relationships between diversity and a healthy ecosystem persist, human-driven pressures of warming oceans and invasive species still diminish ecosystems in various ways.
Durham, NC - The results of a clinical trial released today in STEM CELLS Translational Medicine demonstrate how a topical solution made up of stem cells leads to the regrowth of hair for people with a common type of baldness.
Personal accounts of childhood maltreatment show a stronger association with psychiatric problems compared to legal proof that maltreatment occurred, according to a new study co-written by a King's College London researcher.
The findings indicate that clinical work that focusses on an individual's memories and thinking patterns around abuse and neglect could be more influential on mental health than previously thought.
