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,…
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…
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 hav…
Genes can affect our nutrient tolerance
A new study finds that minor genetic differences can affect the ability to utilize the energy of various nutrients. This work shows how nutritional planning based on genetic data could promote the development of personalized nutrition for health.
Particles released by red blood cells are effective carriers for anti-cancer immunotherapy
A study has demonstrated that nano-sized vesicles released by red blood cells are a viable platform for delivering immunotherapeutic RNA molecules to suppress breast cancer growth and metastasis. The study successfully delivered RIG-I-activating RNAs u…
Study reveals new therapeutic option for head and neck carcinomas
The various manifestations of head and neck carcinomas rank sixth in frequency worldwide and are fatal for about half a million people every year. In a quarter of cases, head and neck squamous cell carcinoma (HNSCC) is caused by human papillomavirus (H…
Promising drug candidates for Crimean-Congo haemorrhagic fever identified
Researchers have identified key signalling pathways that when blocked by existing drug candidates limit reproduction of the Crimean-Congo haemorrhagic fever (CCHF) virus. The findings offer hope for patients affected by this potentially deadly disease.
When the rust settles: Uncovering the movements of coffee leaf rust disease
Researchers have found a high incidence of coffee leaf rust (CLR) disease in Vietnam, the world’s second-largest coffee producer. Potential origins and migration routes were revealed, as well as a close genetic relationship with several Central and Sou…
Phase transitions in the early universe and their signals
The early universe may chirp about unknown physics. A research team has demonstrated how an early universe phase transition will lead to gravitational wave signals potentially visible in the upcoming satellite missions.
Psychiatric symptoms in Alzheimer´s disease
In addition to memory problems and other cognitive symptoms, most people with Alzheimer’s disease also suffer from mental health issues. It has long been unclear whether these occur because of tissue changes in the brain, or whether they represent psyc…
A better way to reduce child maltreatment
A first-of-its-kind national study has found that a special program adopted in many states to help some families at risk of child maltreatment has been surprisingly successful.
Novel treatment effective for sidewall brain aneurysm, study finds
A novel mesh plug that has been traditionally used to treat brain aneurysms occurring where the blood vessels branch out was found to be equally effective in treating aneurysms on the side of the vessel, according to a new study.
Fruit snack or edible? Study finds some cannabis products look like popular snacks
Some cannabis edibles look remarkably like popular snack foods and may be easily confused for them, finds a new study.
Researchers take step toward developing ‘electric eye’
Using nanotechnology, scientists have created a newly designed neuromorphic electronic device that endows microrobotics with colorful vision. The newly designed artificial vision device could have far-reaching applications for the fields of medicine, a…
About 30 percent of COVID patients develop ‘Long COVID,’ research finds
New research finds that 30 percent of people treated for COVID-19 developed Post Acute Sequelae of COVID-19 (PASC), most commonly known as ‘Long COVID.’
Guiding a superconducting future with graphene quantum magic
Superconductors are materials that conduct electrical current with practically no electrical resistance at all. This ability makes them extremely interesting and attractive for a plethora of applications such as loss-less power cables, electric motors …
No glacial fertilization effect in the Antarctic Ocean
Can iron-rich dust fertilize the ocean, stimulate algae growth there, and thereby capture carbon dioxide from the atmosphere? An international research team used deep-sea sediment cores from the Scotia Sea to investigate whether this hypothetical green…
The origins and ID of pancreatic endocrine cells
Scientists show that endocrine stem cells in the pancreas disappear after birth, and detail the genetic identity of the different types of pancreatic hormone-producing cells.
