Long COVID and severe COVID-19 infections associated with Epstein-Barr virus reactivation

Eurekalert - Jul 21 2021 - 00:07
Two recently published studies indicate Epstein-Barr virus (EBV) reactivation may play a role both in the development of long COVID symptoms, as well as severe COVID-19 cases. A study in Pathogens found over 73% of COVID-19 patients who were experiencing long Covid symptoms were also positive for EBV reactivation. A study in Scientific Reports by Nature found EBV reactivation was also associated with COVID-19 severity.

Inheriting mother's friends key to hyena success

Eurekalert - Jul 21 2021 - 00:07
In the wild, inheriting advantageous physical traits may be the difference between a long life and a short one. But for the spotted hyena, another kind of inheritance, one that has nothing to do with genetics, turns out to be extremely important for health and longevity -- social networks inherited from their mothers.

Evidence of sustained benefits of pimavanserin for dementia-related psychosis

Eurekalert - Jul 21 2021 - 00:07
A new paper published in the New England Journal of Medicine outlines a clinical trial, conducted in 392 people with psychosis associated with Alzheimer's disease, Parkinson's disease, Lewy body, frontotemporal, or vascular dementia. All participants were given pimavanserin for 12 weeks. Those who met a threshold of symptom improvement were then assigned to pimavanserin or placebo for up to 26 weeks.

New simulator helps robots sharpen their cutting skills

Eurekalert - Jul 21 2021 - 00:07
Researchers from the University of Southern California and NVIDIA have unveiled a new simulator for robotic cutting that can accurately reproduce the forces acting on a knife as it slices through common foodstuffs, such as fruit and vegetables. The system could also simulate cutting through human tissue, offering potential applications in surgical robotics. The paper was presented at the Robotics: Science and Systems (RSS) Conference 2021 on July 16.

Study finds lifting advice doesn't stand up for everyone

Eurekalert - Jul 21 2021 - 00:07
Commonly accepted advice to keep a straight back and squat while lifting in order to avoid back pain has been challenged by new Curtin University research.The research examined people who had regularly performed manual lifting through their occupation for more than five years and found those who experienced low back pain as a result were more likely to use the recommended technique of squatting and keeping a straight back, while those without back pain tended not to adhere to the recommended lifting advice.

Powerline failures and wind speeds are strongest drivers of land area burned by Santa Ana wind fires

Eurekalert - Jul 21 2021 - 00:07
Every year, Santa Ana Winds drive some of the largest wildfires in Southern California during autumn and winter, and a new analysis of 71 years of data suggests that the total amount of land burned is determined more by wind speed and power line ignitions than by temperature and precipitation. The findings suggest that maintaining utility lines and carefully planning
