Disasters could disrupt care for opioid use disorder in most vulnerable communities
The COVID-19 pandemic has spiked the overdose death rate from opioid use. For people who rely on medications (buprenorphine, methadone, and extended-release naltrexone) to treat opioid use disorders, the pandemic and such natural disasters as tornados, hurricanes, and wildfires can disrupt access to medications. And new research finds that the location of medication treatment services makes treatment interruption likely where those disruptions exist.

New research predicts the disappearance of Olympic Peninsula glaciers
By 2070, the glaciers on the Olympic Peninsula, in Washington State, will have largely disappeared, according to a new study. Although some glaciers will probably remain -- albeit as tiny shells of their former selves. Since about 1900 the region has lost half of its glacier area and since 1980, 35 glaciers and 16 perennial snowfields have disappeared.

Jupiter's moon has splendid dunes
Scientists have long wondered how Jupiter's innermost moon, Io, has meandering ridges as grand as any that can be seen in movies like 'Dune.' Now, a research study has provided a new explanation of how dunes can form even on a surface as icy and roiling as Io's.

A new understanding of how the immune system deals with malaria
By analysing samples from patients who have been treated for malaria in Sweden, researchers can now describe how the immune system acts to protect the body after a malaria infection. The results provide knowledge that can aid in the development of more effective vaccines against the disease.

Sending out bacteria-carrying mosquitoes to protect people from dengue
Researchers developed a model to spatially distribute mosquitoes infected with Wolbachia bacteria, which reduce the transmission of the dengue virus. The researchers use real data on human and vector activity in a framework that can be analyzed from a mathematical point of view, allowing them to re-create and understand the epidemiological situation and identify those geographical areas with the greatest vulnerability, creating a ranking of areas that prioritizes those where Wolbachia-carrying mosquitoes can have the strongest and most beneficial impact on the spread of the virus.

New approach against chronic inflammation: Treating mice with so-called 'nanobodies'
Researchers have succeeded in mitigating chronic inflammation in mice using customized 'mini-antibodies.' These nanobodies enabled them to dissolve molecular complexes in tissue that normally activate the immune system. The nanobodies produced may in future help to slow down unwanted inflammatory reactions that cause diseases such as arthritis or neurodegeneration.

Most vital strategies for successfully implementing changes in industry
Researchers have conducted a study in which they studied change initiatives at more than 600 architecture, engineering and construction firms in North America. They found those that were very successful and sustainable used six key strategies, and that effective change agents and a realistic timeline were vital to making an initiative a lasting success.

Cross-racial study of 1.87m vets shows wide disparities in dementia
In what is believed to be the largest study to date on race and dementia, researchers tracked health and demographic data from close to two million veterans. It compared rates of dementia across five racial groups and showed significant race-based variations in the incidence of the condition.

Almost ready for prime time: Deep UV photodetectors head to real-world testing
Researchers are asking why, after decades of development and promising results, ultrawide bandgap photodetectors with deep UV capabilities haven't enjoyed widespread adoption, and are taking stock of advancements and challenges in the field. Unlike their silicon-based counterparts, UWBG photodetectors made from aluminum gallium nitride and gallium (III) oxide are more efficient, can tailor cutoff wavelengths, and do not need optical filters to reject visible or infrared wavelengths for solar-blind applications.

Biologists find new protective factor against excessive lipid accumulation in liver of obese mouse
Non-alcoholic fatty liver disease (NAFLD), commonly known as fatty liver disease, is a prevalent disease frequently seen in obese people. Having high fat content in the liver is detrimental as it is strongly associated with severe health problems like diabetes, high blood pressure, and liver cancer. A research team uncovers a new protective mechanism against this disorder.

Researchers create 3D model for rare neuromuscular disorders, setting stage for clinical trial
Scientists have created a bioengineered 3-D model that mimics the biology of two rare diseases. The researchers used the 'tissue chip' model to show how a drug could potentially treat the diseases, providing data for a drug company's FDA submission for authorization for clinical testing. This is one of the first examples of using primarily tissue chip data for an FDA application to test the efficacy of a candidate drug for rare diseases.

Nanoparticles prove effective against the yellow fever mosquito
Before being accidentally introduced to the New World by the 16th century slave trade, the yellow fever mosquito was a species native only to Africa. Highly adaptable, it has since become an invasive species in North America, but researchers at may have found a way to squash the pesky population in its juvenile stages.
