| New study sheds light on why opioids can cause gastrointestinal problems Posted: 06 Jul 2022 01:53 PM PDT 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 pump inhibitor drugs like omeprazole, an over-the-counter medication commonly used to reduce stomach acid. |
| Birdwatching brings millions of dollars to Alaska Posted: 06 Jul 2022 01:53 PM PDT 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 Posted: 06 Jul 2022 12:31 PM PDT 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 long-term monitoring and citizen science efforts are invaluable for ecological forecasting and discovery. |
| Using the power of the sun to roast green chile Posted: 06 Jul 2022 12:31 PM PDT 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 roast green chile. The results of his experiments roasting chile with concentrated sunlight will be shared at the American Society of Mechanical Engineers' conference on energy and sustainability next week. |
| Connecting the spots: First comprehensive review of national jaguar protection laws Posted: 06 Jul 2022 10:33 AM PDT Conservationists have conducted the first comprehensive review of national laws across the range of the jaguar (Panthera onca) to show opportunities for strengthening legal protections of the largest cat species found in the Americas. |
| Multi-layered strategies needed to protect public health from oil and gas drilling impacts Posted: 06 Jul 2022 10:33 AM PDT A group of public health experts from several universities and organizations is urging adoption of a multi-layered approach when developing policies to mitigate the impact of gas and oil production operations. They lay out a framework for decision-making, which they say would facilitate the application of more public health protective measures. |
| Solar-powered chemistry uses carbon dioxide and water to make feedstock for fuels, chemicals Posted: 06 Jul 2022 10:33 AM PDT Solar-powered synthesis gas could recycle carbon dioxide into fuels and useful chemicals, an international team of researchers has shown. |
| 'Supergene' wreaks havoc in a genome Posted: 06 Jul 2022 10:33 AM PDT Biologists have used population genomics to shed light on the evolution and consequences of a selfish genetic element known as Segregation Distorter (SD). The researchers report that SD has caused dramatic changes in chromosome organization and genetic diversity. |
| Validating a new method for assessing the antimicrobial efficacy of domestic cleaning products Posted: 06 Jul 2022 10:33 AM PDT Researchers have statistically validated a new method for assessing the antimicrobial efficacy of detergents and textile additives in domestic environments. The results reveal the validity of the new protocol, which has been presented to the European Committee for Standardisation (CEN) requesting it to become the European standard. |
| New method for studying functionality of microbiota Posted: 06 Jul 2022 10:33 AM PDT A research group has developed a new method for studying the functionality of microbiota through metaproteomics. The new method poses broad potential for the study of microbiota on a new, functional level. The characterization of the functionality of gut microbiota is central in the study of human health and disease as well as disease prediction, prevention, and treatment. Previous studies have mainly focused on cataloguing the composition of microbiota, but little is known about the functionality of the human gut microbiota. |
| Climate warming could deepen environmental injustice in urban areas Posted: 06 Jul 2022 10:33 AM PDT Extreme heat events could become more intense and frequent both locally and globally, increasing the risk of harm to health and global economies, according to a new study. |
| Posted: 06 Jul 2022 10:33 AM PDT The bacterium Photorhabdus luminescens is already used as bioinsecticide to protect crops against a wide range of insect pests. Researchers have recently demonstrated that P. luminescens can also protect plants against fungal infection. |
| Stronger integration of international negotiations needed to protect the ocean Posted: 06 Jul 2022 10:33 AM PDT International solutions are needed to protect the ocean. Two sets of regulations currently under development offer an opportunity to expand protections, but a greater degree of alignment between the two must be achieved. In a new scientific article, researchers outline how this could be realized. |
| Volcano's eruption will help scientists plot weather, climate Posted: 06 Jul 2022 10:33 AM PDT As it captivated people around the world, the January eruption of the Hunga Tonga-Hunga Ha'apai volcano gave scientists a once-in-a-lifetime chance to study how the atmosphere works, unlocking keys to better predict the weather and changing climate. |
| Case solved: The biosynthesis of strychnine elucidated Posted: 06 Jul 2022 10:32 AM PDT A research team has disclosed the complete biosynthetic pathway for the formation of strychnine in the plant species Strychnos nux-vomica (poison nut). The researchers identified all genes involved in the biosynthesis of strychnine and other metabolites and expressed them in the model plant Nicotiana benthamiana. This enabled them to show that these extremely complex and pharmacologically important molecules can be synthesized using 'metabolic engineering' methods. |
