KAIST researchers and their collaborators at home and abroad have successfully demonstrated a new methodology for direct near-field optical imaging of acoustic graphene plasmon fields. This strategy will provide a breakthrough for the practical applications of acoustic graphene plasmon platforms in next-generation, high-performance, graphene-based optoelectronic devices with enhanced light-matter interactions and lower propagation loss.
CHAMPAIGN, Ill. -- Agricultural scientists who study climate change often focus on how increasing atmospheric carbon dioxide levels will affect crop yields. But rising temperatures are likely to complicate the picture, researchers report in a new review of the topic.
Published in the Journal of Experimental Botany, the review explores how higher temperatures influence plant growth and viability despite the greater availability of atmospheric CO2, a key component of photosynthesis.
A team of scientists led by Nanyang Technological University, Singapore (NTU Singapore) has developed a device that can deliver electrical signals to and from plants, opening the door to new technologies that make use of plants.
A quadruple fusion optical and ultrasound imaging system has been developed that allows diagnosis of eye conditions or tumors or to see the environment inside the body using a transparent ultrasound transducer.
PHILADELPHIA - Imposter syndrome is a considerable mental health challenge to many throughout higher education. It is often associated with depression, anxiety, low self-esteem and self-sabotage and other traits. Researchers at the Sidney Kimmel Medical College at Thomas Jefferson University wanted to learn to what extent incoming medical students displayed characteristics of imposter syndrome, and found that up to 87% of an incoming class reported a high or very high degree of imposter syndrome.
PITTSBURGH (March 16, 2021) ... During the swarming of birds or fish, each entity coordinates its location relative to the others, so that the swarm moves as one larger, coherent unit. Fireflies on the other hand coordinate their temporal behavior: within a group, they eventually all flash on and off at the same time and thus act as synchronized oscillators.
A Florida State University professor's research could help quantum computing fulfill its promise as a powerful computational tool.
William Oates, the Cummins Inc. Professor in Mechanical Engineering and chair of the Department of Mechanical Engineering at the FAMU-FSU College of Engineering, and postdoctoral researcher Guanglei Xu found a way to automatically infer parameters used in an important quantum Boltzmann machine algorithm for machine learning applications.
Their findings were published in Scientific Reports.
(Portland - March 15) Results of a clinical study conducted by researchers in Manaus, Brazil, show that the Gazelle® Malaria test outperformed Rapid Diagnostic Tests (RDTs) and was nearly as accurate as more expensive and time-consuming expert microscopy in detecting Plasmodium vivax (P. vivax) malaria. The data was published Friday, March 12 in the Malaria Journal.
Copper nanomaterials with a cubic shape so perfect that they form neatly aligned stacks when brought together have been created by researchers at KAUST. The cuboid copper nanoclusters, developed by rational design, are a new member of an exotic nanomaterial family that has shown many promising properties but has remained very hard to make.
The habitats of freshwater fish species are threatened by global warming, mainly due to rising water temperatures. A 3.2-degree Celsius increase in global mean temperature would threaten more than half of the habitat for one third of all freshwater fish species. The number of species at risk is ten times smaller if warming is limited to 1.5 degrees. This is the conclusion of a study led by Radboud University, in collaboration with Utrecht University, PBL Netherlands Environmental Assessment Agency, Leiden University and others, and published in Nature Communications on March 15th.
Robotics researchers are developing exoskeletons and prosthetic legs capable of thinking and making control decisions on their own using sophisticated artificial intelligence (AI) technology.
The system combines computer vision and deep-learning AI to mimic how able-bodied people walk by seeing their surroundings and adjusting their movements.
Dr Daniel Montesinos is a Senior Research Fellow at the Australian Tropical Herbarium, at James Cook University in Cairns. He is studying weeds to better understand (among other things) how they might respond to climate change.
He said most invasive plants are characterised by their rapid pace when it comes to taking up nutrients, growing, and reproducing - and they're even faster in the regions they invade.
Last December, the Parliament of Catalonia unanimously approved the incorporation into its legislation of second-order violence against those who give their support to victims of violence against women. A recent study compiles testimonies of victims, and analyses this form of intimidation
During pandemics, protective behaviors need to be motivated by effective communication. A critical factor in understanding a population's response to such a threat is the fear it elicits, since fear both contributes to motivating protective responses, but can also lead to panic-driven behaviors. Furthermore, lockdown measures affect well-being, making it important to identify protective factors that help to maintain high perceived levels of health during restrictions.
We all have a clear picture in mind when we think of metals: We think of solid, unbreakable objects that conduct electricity and exhibit a typical metallic sheen. The behaviour of classical metals, for example their electrical conductivity, can be explained with well-known, well-tested physical theories.
