Smart magnetic soft materials to develop artificial muscles and therapeutic robots
Developing a new generation of artificial muscles and soft nanorobots for drug delivery are some of the long-term goals of 4D-BIOMAP, an ERC research project being undertaken by the Universidad Carlos III de Madrid (UC3M).This project develops cross-cutting bio-magneto-mechanical methodologies to stimulate and control biological processes such as cell migration and proliferation, the organism's electrophysiological response, and the origin and development of soft tissue pathologies.

'Breaking the links' in the chain of violence: Journal of Psychiatric Practice continues series on therapeutic risk management approach
With mass shootings and other seemingly meaningless acts of violence in the headlines all too frequently, strategies to assess the risk and reduce the potential for violent acts are sorely needed. The fourth in a series of five columns devoted to therapeutic risk management of violence - focusing on a method called chain analysis to identify and target pathways leading to violent thoughts and behaviors - appears in the May issue of the Journal of Psychiatric Practice.

Defective epithelial barriers linked to two billion chronic diseases
Humans are exposed to a variety of toxins and chemicals every day. According to the epithelial barrier hypothesis, exposure to many of these substances damages the epithelium, the thin layer of cells that covers the surface of our skin, lungs and intestine. Defective epithelial barriers have been linked to a rise in almost two billion allergic, autoimmune, neurodegenerative and psychiatric diseases.

Cell cytoskeleton as target for new active agents
Through a unique combination of computer simulations and laboratory experiments, researchers at the Paul Scherrer Institute PSI have discovered new binding sites for active agents - against cancer, for example - on a vital protein of the cell cytoskeleton. Eleven of the sites hadn't been known before. The study is now published in the journal Angewandte Chemie International Edition.

ATTR amyloidosis during the COVID-19 Pandemic: Insights from a global medical roundtablp
COVID-19 primarily involves the respiratory system, dysfunction in multiple organ systems is common, particularly in the cardiovascular, gastrointestinal, immune, renal, and nervous systems. Patients with transthyretin amyloidosis (ATTR) (a disease caused by an abnormal misfolded protein that causes buildup of amyloid deposits in the heart, peripheral nervous system including the autonomic nervous system, or other organs) represent a population particularly vulnerable to COVID-19 morbidity due to the multisystem nature of ATTR amyloidosis.

Researchers find association between financial strain due to COVID-19 and depression
Researchers have found an independent association between COVID-19-related income loss and financial strain and depression, according to the latest study from the COVID-19 Resilience Project, run by the Lifespan Brain Institute (LiBI) of Children's Hospital of Philadelphia (CHOP) and Penn Medicine. This association was found in two separate cohorts - one primarily in the United States and one in Israel - and the depressive symptoms worsened over time in participants who were hit financially, above and beyond pandemic-related anxiety.

Just a few atoms thick: New functional materials developed
Researchers have developed an organic-inorganic hybrid crystal which consists of chains in a single direction, yet still forms two-dimensional layers in spite of this. This makes it possible to combine different material components, like pieces in a construction set, to create tailored materials with innovative properties.

Researchers unveil roadmap to expand NY solar energy, meet green goals
Solar-power developers need to explore using lower-quality agricultural land for solar energy, incentivize dual-use (combined agriculture and solar) options, avoid concentrated solar development and engage communities early to achieve New York's green energy goals, according to forthcoming Cornell University research.

Unusual semimetal shows evidence of unique surface conduction states
Scientists at Tokyo Tech experimentally verify the existence of exotic surface conduction states in topological semimetals (TSMs), materials that lie at the boundary between conductors and insulators, by performing voltage scans of these surface states on a thin film sample of a TSM. The findings can pave the way for future study and exploitation of such conduction states in realizing novel, quantum transport phenomena.

Greater effectiveness in the treatment of arrhythmia with radio frequency energy and catheterization
An article published in International Journal of Hyperthermia proposes a more effective protocol for the treatment of cardiac arrhythmias when applying radiofrequency energy at the site of the arrhythmia by catheterization. The research results from the final year project on the bachelor's degree in Biomedical Engineering by Sergi Coderch Navarro, supervised by Ana González Suárez and Oscar Camara, researchers with the PhySense group of the BCN MedTech Research Unit.

Twitter data unveils issues nursing mothers face, informs proposed interventions
Social media has become a platform for new mothers to openly share their experiences of the joys and challenges of parenthood. Researchers at Penn State and Dalhousie University have unraveled the sentiments in nursing mothers' tweets to better understand the factors influencing breastfeeding behaviors. They hope the findings can inform policies and interventions to support and improve resources for nursing mothers, such as breastfeeding support, workplace accommodations and technological aids such as apps.
