New study sheds light on why opioids can cause gastrointestinal problems
- ScienceDaily
- 22/7/6 22:53
Opioids are the gold standard for treatment of chronic and acute pain; however, their use may result in significant gastrointestinal side effects, including nausea, vomiting, and constipation. The reasons behind these side effects are not well understood. A new study reports on how opioids like morphine cause gastric inflammation and how this condition can be reversed through treatment with proton...
Birdwatching brings millions of dollars to Alaska
- ScienceDaily
- 22/7/6 22:53
New research found that nearly 300,000 birders traveled to the state and spent about $378 million in 2016. Birdwatching supported roughly 4,300 jobs in Alaska that year.
Citizen scientists from 200 years ago and today help shed light on climate change trends
- ScienceDaily
- 22/7/6 21:31
Citizen science observations across two centuries reveal a dramatic, climate-driven shift to earlier leaf out and flowering, which varies across settings, species and functional groups. Plants in urban areas, insect pollinated trees, and early-season species show the greatest rate of advancement overall. This unprecedented comparison of historic-modern network observations illustrates how...
Using the power of the sun to roast green chile
- ScienceDaily
- 22/7/6 21:31
Roasting green chile is an important cultural touchstone for New Mexico, but it leads to a seasonal emission of approximately 7,800 metric tons of carbon dioxide -- the equivalent of driving 1,700 cars for a year. Sandia National Laboratories engineer Kenneth Armijo, who grew up on a chile farm in Sabinal, located between Albuquerque and Socorro, New Mexico, thought there was a 'greener' way to...

- ScienceDaily
- 22/7/6 21:30
Adolescent depression and behavior problems are on the rise and paternal depression may be contributing to this increase, regardless of whether the fathers and children are genetically related, according to new research.
Solving algorithm 'amnesia' reveals clues to how we learn
- ScienceDaily
- 22/7/6 21:30

Helping teens channel stress, grow in resilience
- ScienceDaily
- 22/7/6 21:30
The mental health crisis among teens has prompted an urgent quest for preventive interventions. Researchers believe they have one. As the team explains in a recent study, the 30-minute online training module teaches teenagers to channel their stress responses away from something negative that needs to be feared and tamped down towards recognizing those responses -- sweaty palms, a racing heart,...
Safety first: How stigma may impact health
- ScienceDaily
- 22/7/6 21:30
Lack of safety, according to a new theory, may have a direct impact on the health of people in marginalized communities, particularly the LGBTQ community. The theory challenges decades of thinking that health disparities in the LGBTQ community are primarily due to encounters with stressful and discriminatory events, a concept called 'minority stress.'
Death of a family member may increase heart failure mortality risk
