There is no evidence for the commonly held belief that nut allergens can be spread through aircraft ventilation systems, say allergy and aviation medicine specialists in an evidence review published in the Archives of Disease in Childhood. Allergen residues on surfaces, such as tray tables, and seat-back video screens, pose the main risk—a risk that is likely heightened by the fast turnaround times deployed by many low-cost carriers, they suggest. And allergic reactions to foods are around 10 to 100 times less common during flights than they are ‘on the ground,’ they point out, although this could be due to passengers with food allergies ...

Published in Molecular Psychiatry, this is the first study to suggest that the use of high potency cannabis leaves a distinct mark on DNA, providing valuable insights into the biological impact of cannabis use. High potency cannabis is defined as having Delta-9-tetrahydrocannabinol (THC) content of 10 per cent or more.  The research also showed the effect of cannabis use on DNA is different in people experiencing their first episode of psychosis compared to users who have never experienced psychosis, ...

Teleoperated robots for gathering moon dust are a step closer, according to new research by scientists at the University of Bristol. The team were able to complete a sample collection task by controlling a virtual simulation, which then sent commands to a physical robot to mirror the simulation’s actions. They were able to do so while only monitoring the simulation - without needing physical camera streams - meaning this tool could be particularly useful for delayed teleoperation on the Moon. Alongside a boom in lunar lander missions ...

A new world record in wireless transmission, promising faster and more reliable wireless communications, has been set by researchers from UCL. The team successfully sent data over the air at a speed of 938 Gigabits per second (Gb/s) over a record frequency range of 5-150 Gigahertz (GHz). This speed is up to 9,380 times faster than the best average 5G download speed in the UK, which is currently 100 Megabits per second (Mb/s) or over1. The total bandwidth of 145GHz is more than five times higher than the previous wireless transmission world record. Typically, wireless networks transmit information using radio waves over ...

A research group led by Joshua Neunuebel at the University of Delaware, USA, tracked the behavior of mice using machine learning to understand how they handle aggressive behavior from other mice. The researchers’ findings, published on October 15th in the open-access journal PLOS Biology, show that male mice deescalate aggressive encounters by running over to a female mouse to distract the aggressive male mouse. The researchers recorded groups of two male and two female mice interacting over five hours. Like many other animals, mice have social hierarchies, and in almost each group recorded, one male was always significantly more aggressive towards the other. Social interactions ...

In an era where mental health awareness is at the forefront of public discourse, a new historical review is shedding light on the often-overlooked French contributions to our understanding of depression. Published in Genomic Psychiatry, the study by Dr. Kenneth S. Kendler and Virginia Justis of Virginia Commonwealth University examines a seminal 1897 French monograph that helped shape modern concepts of melancholia and depression. The review focuses on "La Mélancolie" by Jacques Roubinovitch ...
