Depression, anxiety may hinder healing in young patients with hip pain

Pre-operative depression, anxiety linked to worse postsurgical outcomes Credit: Matt Miller New research suggests that physicians evaluating young patients with hip pain should consider more than such patients’ physical health. They also should consider screening those patients for clinical depression and anxiety — impairments that researchers at Washington University School of Medicine in St. Louis have found can have a negative impact on outcomes following hip surgery, such as pain,

Fundamental discoveries for future nanotools: Chemists distinguish multiple weak forces

Credit: Image by Shuichi Hiraoka, CC-BY-ND The process of building a tiny cube has revealed some of the fundamental mysteries of how molecules bind together in natural environments. Researchers hope to apply this knowledge to future projects designing complex structures that can mimic life. When two molecules surrounded by water move towards each other, part of their initial attraction is sometimes due to the chemical force to repel water —

Estimates of ecosystem carbon mitigation improved towards the goal of the Paris agreement

Credit: Masayuki Kondo Approximately 30 percent of CO2 emitted to the atmosphere by human activities, mainly the use of fossil fuels and deforestation, is taken up by terrestrial ecosystems such as forests and grasslands. The recent reports from the IPCC concluded that new land-use options to enhance this terrestrial carbon sink are needed to meet the goals of the Paris Agreement on Climate. “Yet, it is important to understand the

A guidebook for local governments and CBOs to support elderly people to take out the trash

Credit: NIES One of the issues related to waste management in aging society is helping elderly people who find it difficult to take out the trash. In the face of the aging of society and increasing numbers of nuclear (one- and two-generation) family households, more and more elderly people are in need of support. In Japan, many local governments have introduced a program to support elderly people taking out their

Antiarrhythmic drug identified as potential treatment for pulmonary arterial hypertension

Findings reported in The American Journal of Pathology suggest dofetilide may counteract pathological changes in potassium channels associated with pulmonary arterial hypertension in humans and rats Credit: Shults, N.V., Rybka, V., Suzuki, Y.J., and Brelidze, T.I. Philadelphia, December 12, 2019 – High blood pressure in the lungs, known as pulmonary arterial hypertension (PAH), is a potentially fatal disease caused by obstruction of blood flow in the lungs. A new study

Experiment suggests the best ways to tackle invasive Oregon grape in Belgian coastal dunes

Credit: Tim Adriaens The Belgian coastal dunes, a protected habitat of high conservation value, are getting severely impacted by one of its worst enemies amongst invasive species: the Oregon grape. To help mitigate the detrimental effect of this North American shrub invader, Belgian scientists carried out an experiment to assess the effectiveness of different management methods. The Atlantic coastal dunes form a dynamic and diverse ecosystem, home to a large

Local traditional knowledge can be as accurate as scientific transect monitoring

New research from a cross-organisational consortium in the Amazon has found indigenous knowledge to be as accurate as scientific transect monitoring Credit: Hani El Bizri New research from a cross-organisational consortium in the Amazon has found indigenous knowledge to be as accurate as scientific transect monitoring. The research involved pooling resources between universities and NGO’s, including British universities Oxford Brookes University, Manchester Metropolitan University and the University of Suffolk, to

Bumblebees exposed to Chernobyl-levels of radiation consume more nectar

Credit: Jessica Burrows The study simulated Chernobyl-levels of radiation exposure in a laboratory to investigate the impacts it may be having on insects inhabiting the exclusion zone. Although it has been previously found that bumblebees are sensitive to radiation, few studies have investigated the effects on their fitness. The dose rates of radiation in which negative effects occur are also uncertain. Jessica Burrows, who will be presenting the research at

Flipping the script on novel cancer therapy leads to insights into lupus

Credit: (Image credit: Chen Lab) In the last decade, scientists discovered that blocking a key regulator of the immune system helped unleash the body’s natural defenses against several forms of cancer, opening up a new era of cancer immunotherapy. Now Yale scientists have essentially flipped this script and found that when impaired a molecularly similar regulator can cause the damaging immune system attacks on skin and organs that are the

University of Iowa receives major grant to continue work on Huntington’s disease
