In social experiments, three monkeys sat around a rotary table and took turns offering food to one of the other two monkeys. Certain neurons in the brain responded to the actions of other monkeys in the group and influenced an animal's upcoming decisions to reciprocate or retaliate.
A research team has made a breakthrough in surface science by introducing a new active mechanism of adsorption. Such adsorption-based phenomena, in which molecules are attracted onto a solid surface, are essential for today's catalysts, energy storage and environmental remediation. The research demonstrates how artificial molecular machines grafted on surfaces can be used to recruit molecules...
A study explores how human-caused changes on land can affect aquatic animals, specifically in the case of the fungal pathogen, Cryptococcus gattii.
Engineers have developed a novel approach to design and fabricate thin-film infrared light sources with near-arbitrary spectral output driven by heat, along with a machine learning methodology called inverse design that reduced the optimization time for these devices from weeks or months on a multi-core computer to a few minutes on a consumer-grade desktop.
At the root of global climate change and the worldwide plastics problem are two related carbon-based fuels -- oil and natural gas. Not only are the two among the key drivers of climate change, they are instrumental in the manufacturing of plastics. As storms intensify and become more frequent, the movement of trash from land to our oceans and, and vice versa, is only going to get worse.
Neuroscientists used wireless devices to record the neural activity of freely interacting Egyptian fruit bats, providing researchers with the first glimpse into how the brains of social mammals process complex group interactions.
A material derived from trees could potentially replace liquid electrolytes in next-generation batteries.
Researchers have developed a shape-shifting material that can take and hold any possible shape, paving the way for a new type of multifunctional material that could be used in a range of applications, from robotics and biotechnology to architecture.
Findings show that cell-free DNA in cerebrospinal fluid can be used to detect measurable residual disease and identify patients at risk of relapse.
With the WASA detector, a very special instrument is currently being set up at GSI/FAIR. Together with the fragment separator FRS, it will be used to produce and study so-called hypernuclei during the upcoming experiment period of FAIR Phase 0 in 2022. For this purpose, the assembly, which weighs several tons, is being transferred to the facility in a complex installation procedure.
Physicists have described in theoretical terms how to develop codes that cannot be broken by quantum computers -- computing devices of the future. These codes rely on distributing single photons that share a quantum character solely among the parties that wish to communicate.
Scientists argue that efforts to understand human cognition should expand beyond the study of individual brains. They call on neuroscientists to incorporate evidence from social science disciplines to better understand how people think.
In research that could inform future high-performance nanomaterials, a study has uncovered how mollusks build ultradurable structures with a level of symmetry that outstrips everything else in the natural world, with the exception of individual atoms.
A new model sheds light on the function of a protein that is a major player in cancer growth, and their results could one day help researchers determine better ways to stop the spread of cancer.
A new organic peroxide molecule, BMPF releases fluorescence under mechanical stress and could be incorporated into polymer networks for mechanofunctional design. BMPF-linked polymers are also stable at relatively high temperatures and could pave the way for highly selective and efficient small-molecule-releasing systems with applications in imaging and drug delivery.
Scientists demonstrate that breaking the trade-off problem between thermopower and conductivity improves thermoelectric performance. They suggest introducing lattice strain into Mott insulator oxide LaTiO3 converts the electronic state to metal, and increases both thermopower and conductivity to induce a 100-fold increase in power factor, which in turn enables the conversion of waste heat to...
By combining Hubble Space Telescope observations with theoretical models, a team of astronomers has gained insights into the chemical and physical makeup of a variety of exoplanets known as hot Jupiters. The findings provide a new and improved 'field guide' for this group of planets and inform ideas about planet formation in general.
Light plays a critical role in enabling 21st century quantum information applications. Limited by size, engineers need to miniaturize quantum devices, which requires re-thinking certain components for harnessing light. Researchers have designed a simple, compact photonic circuit that uses sound waves to rein in light. The team's measurements show that their approach to isolation currently...
History's greatest couples rely on communication to make them so strong their power cannot be denied. But that's not just true for people, it's also true for lasers. According to new research from the USC Viterbi School of Engineering, adding two lasers together as a sort of optical 'it couple' promises to make wireless communications faster and more secure than ever before.
By generating a specific mutation in lab mice, researchers determined that a protein domain in an enzyme called adenosine deaminase 1 p150 is necessary for binding and editing certain RNA molecules. Mutant mice showed inhibited growth after birth, as well as abnormally developed organs. Interestingly, their brains showed characteristics similar to encephalopathy seen in humans suffering from...
Researchers have highlighted that the illegal and unsustainable global wildlife trade has bigger ramifications on our everyday lives than you might think.
The discovery could pave the way for advances in electronics, energy storage and sustainability.
Researchers have successfully trialed two new qPCR assays to help detect the presence of transmissible AMR using water and wastewater samples. The scientists present a DNA-based testing method that provides a surrogate for monitoring AMR, which will make AMR screening cheaper and more accessible around the world.
A non-toxic, bacteria-based system can detect when it is inside a cancer cell and then release its payload of therapeutic drugs directly into the cell. The work could lead to effective, targeted therapies for currently untreatable cancers, such as liver or metastatic breast cancer.
