Researchers propose a new 'Reciprocal Inhibition Model' of PTSD, explaining inhomogeneous symptoms by addressing variabilities at neural, attentional, and symptom levels. This model may aid tailored clinical treatment for individual patients.
Researchers at McMaster University have traced the origins of old virus strains used as vaccination strains during the American Civil War, contributing to the eradication of smallpox. The study highlights the importance of understanding the history and evolution of viruses in vaccine development.
Researchers at Max-Planck Institute for Terrestrial Microbiology study signal transmission in baker's yeast to understand how cells balance information accuracy with energy costs. They found that the pheromone signalling pathway contains negative feedback regulations that improve accuracy, but may also impose fitness costs.
A new theory proposes that early Earth's lithosphere heated up and expanded, causing cracks that eventually divided the planet into plates. The model, developed by Dr. Alexander Webb and his team, suggests that volcanic heat loss led to thermal contraction, which in turn caused the outer shell to warm up and expand.
A new relationship between humanity and the ocean is required to secure the continuity of the diverse life support roles provided by the sea. The paper proposes three key transition pathways to make complex ocean systems more resilient and ensure a more sustainable future.
Researchers at the University of Cambridge have created microcapsule technology that fortifies bivalve shellfish with Vitamin A and D, providing a cheap and effective way to address global nutrient deficiencies. This breakthrough could help improve the health of millions while reducing environmental impact.
