Ben-Gurion U. develop new measure continuous traumatic stress impact
"Current scales assess the more commonly known effects of exposure to traumatic stress, mainly post-traumatic stress disorder (PTSD). This limits patient assessment and may lead to misdiagnoses and ineffective treatment," says Dr. Goral. "The research was conducted to address this gap by developing a validated, comprehensive assessment tool, the Continuous Traumatic Stress Response (CTSR) Scale."

UBC Sauder study shows cigarette tax hikes can help boost bigger brands, hurt consumers
For decades, governments and health authorities have tried to steer people away from "vice" products such as tobacco through counter-marketing measures such as tax increases, but according to a new study from the UBC Sauder School of Business, they can help people quit -- but how much they help, and who pays the price, varies significantly.

Bee-impersonating flies show pollinator potential
An observational study found that out of more than 2,400 pollinator visits to flowers at urban and rural farms in in Western Washington about 35% of were made by flies -- most of which were the black-and-yellow-striped syrphid flies. For a few plants, including peas, kale and lilies, flies were the only pollinators observed. Bees still made the majority, about 61%, of floral visits, but the rest were made by other insects and spiders.

12,000 scientific articles a year -- can they all be wrong?
X-ray photoelectron spectroscopy (XPS) is often used to determine the chemical composition of materials. It was developed in the 1960s and is accepted as a standard method in materials science. Researchers at Linköping University, Sweden, however, have shown that the method is often used erroneously.

Twin study is first to reveal genetic risk factors for PTSD and migraine
While scientists have known that PTSD and migraine often co-occur, no-one had studied this link, before now. A new study by the open access publisher Frontiers on identical twins investigates the genetic basis for both migraine and PTSD. It reveals epigenetic risk factors that are shared by PTSD and migraine, suggesting that similar environmental risk factors are at play in both conditions. The findings could help researchers to develop new treatments.

An overview of protected satellite communications in the intelligent age
Protected Satellite Communications constitute one of the key research topics in modern communications and exhibit specific characteristics such as security, intelligence, anti-jamming, and nuclear disaster survivability. In the modern intelligent age, many intelligent-related technologies are introduced into SatCom systems to provide more secure and efficient communication services. In this paper, a comprehensive overview of the protected SatCom systems is presented. Science China Information Sciences reported this paper in the sixth issue of 2021.
