Detecting and identifying explosives with single test

A new test for detecting multiple explosives simultaneously has been developed by UCL scientists. The proof-of-concept sensor is designed to quickly identify and quantify five commonly used explosives in solution to help track toxic contamination in waste water and improve the safety of public spaces.

‘Core’ immune cells reduce symptoms and spread of flu

A four-year study of 1,414 unvaccinated people across England found that 43% of them had immune cells that protected them from symptoms of both seasonal and pandemic influenza, and reduced their chances of shedding the virus by two thirds. The work led by researchers from UCL, Oxford University and Public Health England was funded by the Medical Research Council and Wellcome Trust. (more…)

Having a romantic partner present can make pain feel worse

The support of a romantic partner is often advised for painful medical procedures, but new research from UCL, King’s College London and the University of Hertfordshire finds that this can actually make the pain feel worse. (more…)

Drug tests on mothers’ hair links recreational drug use to birth defects

Drug tests on 517 mothers in English inner city hospitals found that nearly 15% had taken recreational drugs during pregnancy and that mothers of babies with birth defects of the brain were significantly more likely to have taken drugs than mothers with normal babies. The study found no significant links between recreational drug use and any other type of birth defect.

The study was led by a team of UCL researchers co-ordinating data collection from hospitals across London, Bristol and Birmingham and the results are published in the journal PLOS ONE. The study included 213 women whose baby had a type of birth defect with potential links to recreational drug use, 143 women whose baby had a birth defect with no previously reported links to drug use and 161 women whose baby was normally formed.

The bit of your brain that signals how bad things could be

An evolutionarily ancient and tiny part of the brain tracks expectations about nasty events, finds new UCL research funded by the Medical Research Council.

The study, published in Proceedings of the National Academy of Sciences, demonstrates for the first time that the human habenula, half the size of a pea, tracks predictions about negative events, like painful electric shocks, suggesting a role in learning from bad experiences. (more…)

Statistical analysis unveils the hidden patterns in Eurovision voting

Voting for the Eurovision Song Contest has been scrutinised by statistics experts at UCL and Imperial College London, who have found that musical talent is unlikely to be the only element that wins scores – but that the contest is not ‘stitched up’ at the UK’s expense. 

The analysis of voting patterns over the past two decades suggests that widespread support for certain countries’ acts is, however, not driven by prejudice, as the media periodically suggests, but by positive loyalties based on culture, geography, history and migration. But these effects are relatively small – and the team found no evidence to support Sir Terry Wogan’s criticism that the contest is marred by blatant bias and discrimination. (more…)

Tingling sensation caused by Asian spice could help patients with chronic pain

The science behind the tingling sensation caused by eating a popular Asian spice has been explained by researchers at UCL.

The study, which is published in the journal Proceedings of the Royal Society B, helps shed light on the complex interactions between the senses of taste and touch, and could lead to a greater understanding of the causes of the tingling sensations experienced by many chronic pain patients.

Widely used in Asian cooking, the Szechuan pepper was found to mimic the sense of touch in the brain. It chemically activates light-touch fibres on the lips and tongue and sends the equivalent of 50 light taps to the brain per second. (more…)
