In working life it's now almost expected that employees answer work-related emails after hours, or take their laptops with them on holiday. But the blurring of boundaries between work and personal life can affect people's sense of well-being and lead to exhaustion. This is according to Ariane Wepfer of the University of Zurich in Switzerland who, together with her colleagues, published a study in Springer's Journal of Business and Psychology.
Zilin Jiang from Technion -- Israel Institute of Technology and Alexandr Polyanskii from the Moscow Institute of Physics and Technology (MIPT) have proved László Fejes Tóth's zone conjecture. Formulated in 1973, it says that if a unit sphere is completely covered by several zones, their combined width is at least π. The proof, published in the journal Geometric and Functional Analysis, is important for discrete geometry and enables new problems to be formulated.
The forests you see today are not what you will see in the future. That's the overarching finding from a new study on the resilience of Rocky Mountain forests, led by Colorado State University.
Researchers analyzed data from nearly 1,500 sites in five states -- Colorado, Wyoming, Washington, Idaho, and Montana -- and measured more than 63,000 seedlings after 52 wildfires that burned over the past three decades. They wanted to understand if and how changing climate over the last several decades affected post-fire tree regeneration, a key indicator of forest resilience.
Greater Mekong Subregion (GMS) integration has brought about tremendous change to the Southeast Asia region, and this has not only had many benefits but has caused many problems. Moreover the characteristic differences among the GMS countries in terms of trade and investment, society and cultural values, medical information and technology, and the living and work environment have become major health problems in terms of mental disorders.
When a loved one has been hospitalized in intensive care for a critical illness, many family members experience anxiety, depression, post-traumatic stress or other negative effects lasting months, according to new research led by Intermountain Medical Center in Salt Lake City.
The study, published in the journal Critical Care Medicine, suggests that determining which family members are likely to suffer long-term effects could offer guidance to caregivers about how to help them.
For some young people, dealing with life stressors like exposure to violence and family disruption often means turning to negative, risky behaviors -- yet little is known about what can intervene to stop this cycle.
But one long-term study by the University of Cincinnati looks at the link between stressful life events and an increase in substance abuse, risky sexual behaviors and delinquency in a diverse population of 18- to 24-year-old youths. The research also sheds light on distinct coping strategies that can lead to more positive outcomes.
Clinicians and patients often struggle to find the right treatment for anxiety, sometimes cycling through various therapies for months before the patient begins to feel their symptoms improve.
Now, researchers at the University of Illinois at Chicago have found that a brief test that can be performed in the office can help determine whether an antidepressant or a form of talk therapy, called cognitive behavioral therapy or CBT, would be better at relieving symptoms of anxiety in individual patients. Their findings are reported in the journal Neuropsychopharmacology.
Researchers from Case Western Reserve University School of Medicine have discovered how unusually long pieces of RNA work in skin cells. The RNA pieces, called "long non-coding RNAs" or "lncRNAs," help skin cells modulate connective tissue proteins, like collagen, and could represent novel therapeutic targets to promote skin repair.
In a new study, researchers have characterized the effects of a series of opioids on proteins in the brain other than opioid receptors. In the British Journal of Pharmacology study, several synthetic opioids inhibited serotonin and norepinephrine transporters, which may contribute to their analgesic properties but may also increase the risk of serotonin toxicity, a group of symptoms that can include high body temperature, agitation, increased reflexes, tremor, sweating, dilated pupils, and diarrhoea.
WEST LAFAYETTE, Ind. -- Researchers, led by a Purdue University anthropology professor, have found that statistical methods and 3D imaging can be used to accurately measure animal bone cut marks made by prehistoric human butchery, and to help answer pressing questions about human evolution.
