In the US, approximately 19% of all adults have a diagnosable mental illness. Clinic-based services may fall short of meeting patient needs. In the first randomized controlled trial of its kind, a team investigated the impact of a texting intervention as an add-on to a mental health treatment program versus one without it. A new study finds that a text-messaging-based intervention can be a safe,...
Scientists argue that research at synchrotrons could help improve water-purifying materials in ways that might not otherwise be possible.
Two doses of an experimental vaccine to prevent COVID-19 induced robust immune responses and rapidly controlled the coronavirus in the upper and lower airways of rhesus macaques exposed to SARS-CoV-2, scientists report.
Plucky, beautiful and declining in numbers at about a 2% annual rate, the rufous hummingbird makes its long annual migration in different timing and route patterns based the birds' age and sex, new research shows.
The movement of fluids through small capillaries and channels is crucial for processes ranging from blood flow through the brain to power generation and electronic cooling systems, but that movement often stops when the channel is smaller than 10 nanometers. Researchers have reported a new way to stimulate the fluid flow by using a small increase in temperature or voltage.
Teenagers who tend to pay more attention to sad faces are more likely to develop depression, but specifically within the context of stress, according to new research from Binghamton University, State University of New York.
To remove carbon dioxide from the Earth's atmosphere in an effort to slow climate change, scientists must get their hands dirty and peek underground.
When the Shewanella oneidensis bacterium 'breathes' in certain metal and sulfur compounds anaerobically, the way an aerobic organism would process oxygen, it produces materials that could be used to enhance electronics, electrochemical energy storage, and drug-delivery devices. The ability of this bacterium to produce molybdenum disulfide -- a material that is able to transfer electrons easily,...
'A watched pot never boils,' as the saying goes, but that was not the case for researchers watching a 'pot' of liquids formed from DNA. In fact, the opposite happened.
In what they believe is the first study of its kind, researchers report that shifts in the diversity of soil microbial communities can change the soil's ability to sequester carbon, where it usually helps to regulate climate.
Evolutionary and developmental biologists report that they have identified a molecular mechanism that allows an organism to change the way it looks depending on the environment it is exposed to, a process known as phenotypic plasticity.
As climate change becomes increasingly difficult to ignore, scientists are working to diversify and improve alternatives to fossil-fuel-based energy. Renewable bioenergy crops, such as the perennial grass Miscanthus, show promise for cellulosic ethanol production and other uses, but current hybrids are limited by environmental conditions and susceptibility to pests and diseases.
Research examines how the routine use of Artificial Intelligence (AI) in healthcare could help to relieve the economic impact neurodegenerative diseases, such as Alzheimer's.
A pair of recently published studies analyzed how ovarian function in mice responded to various levels of exposure to glyphosate, a chemical extensively used to kill weeds. The results showed exposure changed the level of some ovarian proteins but did not impact ovarian steroid production, an indication glyphosate may not adversely affect reproduction.
Steelhead trout stirring up the sediment of the river bed were detected by seismic sensors. Researchers have used geophones to analyze the trout's nest-building process in detail.
A research group using HIV-1-infected cells performed 'multiomics' analyses, which are technologies recently developed to comprehensively investigate the features of biological samples.In this study, a hematopoietic stem cell-transplanted humanized mouse model infected with a gene-modified HIV-1 was used to reveal multiple characteristics of HIV-1-producing cells in vivo.
New research shows that selecting a targeted retirement fund that ends in a zero could negatively impact your retirement savings. The study identified a ''zero bias'' or tendency for individuals to select retirement funds ending in zero, which affects the amount people contribute to retirement savings and leads to an investment portfolio with an incompatible level of risk.
Researchers have revealed that commercial pesticides can be applied to crops in the Cucurbitaceae family to decrease their accumulation of hydrophobic pollutants, thereby improving crop safety. The team developed two approaches to control the functions of plant proteins related to the transport of hydrophobic pollutants. These findings will lead to these new functions of pesticides being utilized...
Researchers designed a wearable bracelet using sound augmentation to leverage play benefits by employing digital technology. The research team also investigated how sound influences children's play experiences according to their physical, social, and imaginative aspects.
The large-scale loss of eelgrass in a major California estuary -- Morro Bay -- may be causing widespread erosion. Over the last century, Morro Bay has been building up sediment quickly. After the die-off, however, erosion took place in more than 90% of the places where eelgrass previously grew.
Dozens of molecules may tangle up with rogue bundles of tau, a protein that normally gives nerve fibers structure, to cause brain cell damage that contributes to neurodegenerative diseases, a new study shows.
Researchers have discovered a new drug candidate that offers a major advance in the treatment for diabetes. Tested on isolated human and mouse pancreatic islets, mouse and rat cell cultures and animal models of both Type 1 and Type 2 diabetes, the experimental drug significantly improved four detrimental characteristics of diabetes: hyperglycemia; hyperglucagonemia, elevation in the hormone...
New studies indicate that World Trade Center (WTC) first responders are at risk for developing dementia.
A study has pinpointed a number of areas of the human genome that may help explain the neonatal origins of chronic immune and inflammatory diseases of later life, including type 1 diabetes, rheumatoid arthritis and celiac disease.
