There are many ways to generate electricity--batteries, solar panels, wind turbines, and hydroelectric dams, to name a few examples. .... And now there's rust.
New research conducted by scientists at Caltech and Northwestern University shows that thin films of rust--iron oxide--can generate electricity when saltwater flows over them. These films represent an entirely new way of generating electricity and could be used to develop new forms of sustainable power production.
A new research review highlighting the hidden costs of dementia suggests that traditional measures only show the 'tip of the iceberg' of the cost impact on society.
Carbon monoxide is an infamous and silent killer that can cause death in minutes. But while it is deadly for us, some microorganisms actually thrive on it, by using this gas as an energy source.
Associate Professor Chris Greening and his team of microbiologists from the School of Biological Sciences, Monash University, have discovered that some pathogens depend on carbon monoxide to survive when other nutrients are not available.
James Cook University scientists in Australia are using 3D printing to create fuels for rockets, and using tailor-made rocket motors they've built to test the fuels.
JCU lecturer in mechanical engineering Dr Elsa Antunes led the study, which made use of the revolutionary and rapidly advancing 3D printing technology.
The JCU scientists 3D printed fuel grains (solid, plastic-based fuel) for the hybrid rockets using plastics and other materials.
Working with mouse and human tissue, Johns Hopkins Medicine researchers report new evidence that a protein pumped out of some -- but not all -- populations of "helper" cells in the brain, called astrocytes, plays a specific role in directing the formation of connections among neurons needed for learning and forming new memories.
Advanced computer models of diseases can be used to improve diagnosis and treatment. The goal is to develop the models to "digital twins" of individual patients. Those twins may help to computationally identify and try the best medication, before actually treating a patient. The models are the result of an international study, published in the open access journal Genome Medicine.
More support is needed for fosters carers looking after LGBTQ young people, according to new research led by the University of East Anglia (UEA).
Findings from the first ever study of LGBTQ young people in care in England found good examples of foster carers being available and sensitive, and offering acceptance and membership of their family.
Philadelphia, July 30, 2019 - The propensity to overeat may, in part, be a function of the satisfaction derived from eating. A new study in the Journal of the Academy of Nutrition and Dietetics, published by Elsevier, found no significant difference in taste perceptions between participants of normal weight and those who were overweight.
'Tickling' the ear with a small electrical current appears to rebalance the autonomic nervous system for over-55s, potentially slowing down one of the effects of ageing, according to new research.
Scientists found that a short daily therapy delivered for two weeks led to both physiological and wellbeing improvements, including a better quality of life, mood and sleep.
The therapy, called transcutaneous vagus nerve stimulation, delivers a small, painless electrical current to the ear, which sends signals to the body's nervous system through the vagus nerve.
High-energy shock waves driven by solar flares and coronal mass ejections of plasma from the sun erupt throughout the solar system, unleashing magnetic space storms that can damage satellites, disrupt cell phone service and blackout power grids on Earth. Also driving high-energy waves is the solar wind -- plasma that constantly flows from the sun and buffets the Earth's protective magnetic field.
Ethnic enclaves are often viewed as a negative for the integration of immigrants with natives in their new country. But it turns out that ethnic communities can help newly arrived refugees find work, according to a new Stanford study that analyzed a cohort of asylum seekers in Switzerland.
Researchers at the Stanford Immigration Policy Lab found that new refugees were more likely to become employed within their first five years if Swiss officials assigned them to live in an area with a larger community of people who share their nationality, ethnicity or language.
A byproduct of oil and gas production is a large quantity of toxic wastewater called brine. Well-drillers dispose of brine by injecting it into deep rock formations, where its injection can cause earthquakes. Most quakes are relatively small, but some of them have been large and damaging.
MADISON - New research has found that a rare blood cancer can be simulated in the lab only by simultaneously infecting white blood cells with two viruses typically found in the tumors.
The successful creation of stable, cancer-like cells in the lab opens up opportunities for understanding the progression of this and related cancers and, perhaps, developing treatments.
Understanding how biodiversity is shaped by multiple forces is crucial to protect rare species and unique ecosystems. Now an international research team led by the University of Göttingen, German Centre for In-tegrative Biodiversity Research (iDiv) and the Helmholtz Centre for Environmental Research (UFZ), together with the University of Hawai'i at Mānoa, has found that biodiversity is higher on older islands than on younger ones. Furthermore, they found that introduced species are diluting the effects of island age on patterns of local biodiversity.
Researchers at the University of Illinois at Chicago, in collaboration with their colleagues at the University of Hamburg in Germany, have imaged an exotic quantum particle -- called a Majorana fermion -- that can be used as a building block for future qubits and eventually the realization of quantum computers. Their findings are reported in the journal Science Advances.
