Defective Epithelial Barriers Linked to Two Billion Chronic Diseases
Defective Epithelial Barriers Linked to Two Billion Chronic Diseases
Humans are exposed to a variety of toxins and chemicals every day. According to the epithelial barrier hypothesis, exposure to many of these substances damages the epithelium, the thin layer of cells that covers the surface of our skin, lungs and intestine. Defective epithelial barriers have been linked to a rise in almost two billion allergic, autoimmune, neurodegenerative and psychiatric diseases.

Fast changing smells can teach mice about space
Mice can sense extremely fast and subtle changes in the structure of odours and use this to guide their behaviour, according to a new study by UCL and Francis Crick Institute researchers. Odour plumes, like the steam off a hot cup of coffee, are complex and often turbulent structures, and can convey meaningful information about an animal's surroundings, like the movements of a predator or the location of food sources.

Robots could safeguard people from pain
Robots could safeguard people from pain
Interview: Why robots need reflexes Robots could safeguard people from pain Reflexes protect our bodies - for example when we pull our hand back from a hot stove. These protective mechanisms could also be useful for robots. In this interview, Prof. Sami Haddadin and Johannes Kühn of the Munich School of Robotics and Machine Intelligence (MSRM) of the Technical University of Munich (TUM) explain why giving test subjects a "slap on the hand" could lay the foundations for the robots of the future.

Tracking down the tiniest of forces: how T cells detect invaders
Tracking down the tiniest of forces: how T cells detect invaders
T cells use their antigen receptors like sticky fingers - a team from TU Wien and MedUni Vienna was able to observe them doing so. T-cells play a central role in our immune system: by means of their so-called T-cell receptors (TCR) they make out dangerous invaders or cancer cells in the body and then trigger an immune reaction.

Vulnerable older people more likely to experience depression and anxiety during pandemic
Older people who were clinically vulnerable to COVID-19 were at greater risk of deterioration in health and social well-being during the pandemic, according to a new UCL-led study. Research published today in the Journal of Epidemiology and Community Health found that they were more likely to report worse health outcomes than those with no clinical vulnerabilities, including greater depression and anxiety and lower quality of life, even when taking into account pre-pandemic levels of health and social well-being.

The first step to curbing COVID vaccine misinformation is finding out who is most vulnerable
The success of Australia's COVID-19 vaccine rollout will depend on everyone's willingness to receive it. But experts have warned vaccine misinformation online puts Australia's communities at risk, and some more than others. Often, misinformation and undue scepticism are spread on social media. In March, the ABC reported on WeChat posts spreading the false claim the Pfizer vaccine can integrate with people's DNA to transform them into "genetically modified humans'.
