CHAMPAIGN, Ill. -- A proof-of-concept study conducted in a mouse model of Alzheimer's disease offers new evidence that copper isotopes can be used to detect the amyloid-beta protein deposits that form in the brains of people living with - or at risk of developing - Alzheimer's.
LOS ALAMOS, N.M., November 24, 2020 -- Developing safe and sustainable fuels for nuclear energy is an integral part of Los Alamos National Laboratory's energy security mission. Uranium dioxide, a radioactive actinide oxide, is the most widely used nuclear fuel in today's nuclear power plants. A new "combustion synthesis" process recently established for lanthanide metals -- non-radioactive and positioned one row above actinides on the periodic table -- could be a guide for the production of safe, sustainable nuclear fuels.
Researchers from Tel Aviv University (TAU) embarked on an underwater journey to solve a mystery: Why did sponges of the Agelas oroides species, which used to be common in the shallow waters along the Mediterranean coast of Israel, disappear? Today, the species can be found in Israel mainly in deep habitats that exist at a depth of 100 meters (330 feet).
The researchers believe that the main reason for the disappearance of the sponges was the rise in seawater temperatures during the summer months, which in the past 60 years have risen by about 3°C (37°F).
A common insecticide that is a major hazard for honeybees is now effectively detected in honey thanks to a simple new method.
Phosphorus is a necessary nutrient for plants to grow. But when it's applied to plants as part of a chemical fertilizer, phosphorus can react strongly with minerals in the soil, forming complexes with iron, aluminum and calcium. This locks up the phosphorus, preventing plants from being able to access this crucial nutrient.
Medicaid expansion through the Affordable Care Act has insured millions of low-income people in the United States, improving outcomes for patients with many different diseases. But expansion alone has not been enough to improve outcomes for patients with diabetes, according to a new Boston University School of Public Health (BUSPH) study.
The receptive field (RF) of a neuron is the term applied to the space in which the presence of a stimulus alters the response of the same neuron. The responses of visual neurons, as well as visual perception phenomena in general, are highly nonlinear functions of the visual input (in mathematics, nonlinear systems represent phenomena whose behaviour cannot be expressed as the sum of the behaviours of its descriptors).
The 2018 eruption of Kīlauea Volcano was one of the largest volcanic events in Hawai'i in 200 years. This eruption was triggered by a relatively small and rapid change at the volcano after a decade-long build-up of pressure in the upper parts of the volcano, according to a recent study published in Nature Communications by earth scientists from the University of Hawai'i (UH) at Mānoa and U.S. Geological Survey (USGS).
OAK BROOK, Ill. - Anxiety is associated with an increased rate of progression from mild cognitive impairment to Alzheimer's disease, according to a study being presented at the annual meeting of the Radiological Society of North America (RSNA).
Alzheimer's disease represents a major public health crisis worldwide. The number of deaths from the disease has more than doubled since 2000, and it is currently the fifth-leading cause of death among individuals over 65 in the U.S.
When the words "artificial intelligence" (AI) come to mind, your first thoughts may be of super-smart computers, or robots that perform tasks without needing any help from humans. Now, a multi-institutional team including researchers from the National Institute of Standards and Technology (NIST) has accomplished something not too far off: They developed an AI algorithm called CAMEO that discovered a potentially useful new material without requiring additional training from scientists.
Durham, NC - A new treatment for atherosclerosis, commonly known as hardening of the arteries, may be on the horizon, according to a study released today in STEM CELLS Translational Medicine (SCTM). The study demonstrates how injecting mice with early outgrowth cells (EOCs), after first treating the cells with chemicals to activate a type of protein called liver x receptor (LXR), slows the development of this disease.
New research has demonstrated how, in contrast to encroachment by the invasive alien tree species Prosopis julifora (known as `Mathenge` -in Kenya or `Promi` in Baringo), restoration of grasslands in tropical semi-arid regions can both mitigate the impacts of climate change and restore key benefits usually provided by healthy grasslands for pastoralists and agro-pastoralist communities.
WEST LAFAYETTE, Ind. - A new therapy for influenza virus infections that may also prove effective against many other pathogenic virus infections, including HIV and COVID-19, has been developed by Purdue University scientists.
In an average year, more than 2 million people in the United States are hospitalized with the flu, and 30,000 to 80,000 of them die from the flu or related complications.
The Purdue team's work is detailed in Nature Communications and uses a targeted therapy approach against the virus infections.
In a noisy room with many speakers, hearing aids can suppress background noise, but they have difficulties isolating one voice - that of the person you're talking to at a party, for instance. KU Leuven researchers have now addressed that issue with a technique that uses brainwaves to determine within one second whom you're listening to.
We rely on water to quench our thirst and to irrigate bountiful farmland. But what do you do when that once pristine water is polluted with wastewater from abandoned copper mines?
A promising solution relies on materials that capture heavy metal atoms, such as copper ions, from wastewater through a separation process called adsorption. But commercially available copper-ion-capture products still lack the chemical specificity and load capacity to precisely separate heavy metals from water.
