Microgravity and cellular adaptation
Based on real-time readings on the ISS conducted by ESA astronaut Samantha Cristoforetti, University of Zurich scientists Oliver Ullrich and Cora Thiel can now reveal that cells are able to respond to changes in gravitational conditions very quickly and continue functioning. The research team used the alleged oxidative burst an old evolutionary mechanism to exterminate bacteria…

Researchers identify how Ebola virus disables the human immune system
A research study by scientists at the University of Texas Medical Branch in Galveston sheds light on how Ebola effectively disables the human immune system. Virologist Alex Bukreyev, UTMB professor and senior author of the study, said the research team engineered versions of the Ebola virus in order to understand its effects on immune system. The…

The role of PRC2 in controlling gene activity in human stem cells.
Researchers at the Babraham Institute have revealed a new understanding of the molecular switches that control gene activity in human embryonic stem cells. In the developing embryo and during the specialisation of stem cells, the activity of genes must be tightly controlled so that the correct genes are switched on and off at the right…

Antibiotics versus surgery in acute appendicitis
A systemic review of research literature by scientists at the University of Southampton shows that antibiotics may be an effective treatment for acute non-complicated appendicitis in children, instead of surgery. The research paper is published in Pediatrics. The condition, which causes the appendix – a small organ attached to the large intestine – to become inflamed due to a…

Peripheral vision reaction time assessment to diagnose mild traumatic brain injury patients
A new test using peripheral vision reaction time could lead to earlier diagnosis and more effective treatment of mild traumatic brain injury, often referred to as a concussion, according to Peter J. Bergold, PhD, professor of physiology and pharmacology at SUNY Downstate Medical Center and corresponding author of a study published by the Journal of Neurotrauma. While…
