Rural residents at greater risk of maternal morbidity and mortality compared to urban residents
Childbirth is increasingly risky in the United States. Maternal deaths and potentially life-threatening complications - called severe maternal morbidity - are climbing. This reality is especially challenging for rural communities, which face declining access to obstetric services. According to the Centers for Disease Control and Prevention, there are approximately 700 maternal deaths and an additional 50,000 cases of severe maternal morbidity in the U.S. every year.

Chronic opioid treatment may raise risk of post-traumatic stress disorder
While opioids are often prescribed to treat people with trauma-related pain, a new UCLA-led study suggests doctors should use caution before prescribing the drug to those they believe may experience severe stress in the future, in order to reduce the risk the patient will develop PTSD. In the study, researchers administered doses of the opioid morphine to a group of 22 mice for one week, then gave the mice relatively strong foot shocks.

One dose of radiotherapy as effective as five doses for cancer in the spine
A single dose of radiotherapy is as "effective" as five doses for end-of-life cancer patients suffering with painful spinal canal compression, finds a large study conducted by UCL. Spinal canal compression is a common complication in cancer patients when the cancer has spread to their spine. Radiotherapy is used to control pain and alleviate symptoms.

World first as artificial neurons developed to cure chronic diseases
Artificial neurons on silicon chips that behave just like the real thing have been invented by scientists - a first-of-its-kind achievement with enormous scope for medical devices to cure chronic diseases, such as heart failure, Alzheimer's, and other diseases of neuronal degeneration. Critically the artificial neurons not only behave just like biological neurons but only need one billionth the power of a microprocessor, making them ideally suited for use in medical implants and other bio-electronic devices.

For some corals, meals can come with a side of microplastics
Under a black light, fluorescent green microplastics are seen in the water during a small demonstration experiment. In the 2018 experiment described in the paper, cauliflower coral (above) ingested microplastics when prey was also present in the water, but avoided eating microplastics when no prey was there.

Rare Disease Q&A: What Rare Diseases Are and Why That Matters
Rare Disease Q&A: What Rare Diseases Are and Why That Matters
Rare diseases are … rare, right? Not as rare as you might think. As much as 10% of the population is thought to have a "rare disease." Unfortunately, due to a lack of understanding, many rare diseases remain very difficult to diagnose and treat. Inspired by the enormous unmet needs of people with rare diseases, a group of scientists from across the globe has teamed up to develop open-access tools and resources for sharing disease characteristics and treatment information.

Cultural differences account for global gap in online regulation - study
Differences in cultural values have led some countries to tackle the spectre of cyber-attacks with increased internet regulation, whilst others have taken a 'hands-off' approach to online security - a new study shows. Internet users gravitate towards one of two 'poles' of social values. Risk-taking users are found in 'competitive' national cultures prompting heavy regulation, whilst web users in 'co-operative' nations exhibit less risky behaviour requiring lighter regulation.

Paradoxical replacement tissue for medicine
Paradoxical replacement tissue for medicine
A material that thickens when you pull on it seems to contradict the laws of physics. However, the so-called auxetic effect, which also occurs in nature, is interesting for a number of applications. A new Empa study recently published in "Nature Communications" shows how this amazing behavior can be improved - and even used to treat injuries and tissue damage.

Analysis: We may have solved the mystery of how landslides form on Mars
Mars's huge landslides can move at speeds of up to 360 kilometres an hour for up to tens of kilometres. PhD candidate Giulia Magnarini and Dr Tom Mitchell (UCL Earth Sciences) write about how these landslides may have formed. Some landslides on Mars seem to defy an important law of physics. "Long, runout landslides" are formed by huge volumes of rock and soil moving downslope, largely due to the force of gravity.

Shows why visceral fat increases with age and impairs metabolism
Aging is associated with increased inflammation and metabolic disease, including the accumulation of visceral fat - fat stored in the abdominal cavity - which is thought to contribute to inflammation. New research from University of Minnesota faculty member Christina Camell has helped uncover why visceral fat increases with age and points to new treatment possibilities for improving metabolic health.

Underground answers
As the world waxes warmer, scientists are scrambling to prioritize conservation efforts. A new global study of earthworm diversity suggests looking at soil, as climate change could seriously affect earthworms and the many functions they provide. Based on data compiled from 6,928 sites in 57 countries (including over 100 sites sampled by University of Minnesota researcher and study coauthor Adrian Wackett), the work reveals that climate variables-temperature and especially precipitation-influence earthworm distributions and diversity far more than the properties of the soils they inhabit.
