Capybaras, penguins and giant Galapagos tortoises lured on scales for weigh-in
Priscilla, a 30-year-old giant Galapagos tortoise, was lured onto a board scale with a lettuce snack while the Humboldt penguins jostled in line for zookeeper Jessica Ray on Tuesday.
There are more than 10,000 animals at the zoo across 4,000 species.
The record was expected to go to Molly the giraffe, who usually weighs about 700 kilos.
London Zoo's animals are weighed and measured on a regular basis as way of monitoring their health, development and identifying pregnancies.
Zookeepers employ different training methods or techniques to get individuals to step on to the scales.
Many of the zoo's animals are trained to perch on a scale while zookeepers note down their measurements while, for some, scales may be placed in doorways or disguised in their habitats, meaning the animal can be weighed without realising.
London Zoo's animal operations manager Daniel Simmonds said: 'The London Zoo annual weigh-in is not just about numbers on a scale; regular weigh-ins help zookeepers track the health of our animals – including the capybaras, tortoises and penguins – and genuinely help us manage the care of these animals, who play a vital role in our global conservation efforts.'
Each measurement taken is added to the zoological information management system, a database shared with animal carers and conservationists all over the world that helps to compare important information on thousands of endangered species.
The zoo cares for a range of species, from towering giraffes to tiny Darwin's frogs, which are one of the zoo's smallest creatures, measuring two centimetres in length and under two grams in weight.

Largest study on youth vaping suggests it is a gateway to smoking
Children who vape are more likely to go on to be smokers, be diagnosed with asthma and have poor mental health, a new analysis suggests. The largest global review on vaping in young people found 'consistent evidence' that children who vape are three times more likely to go on to become smokers. The study also pointed to links between vaping and increased odds of respiratory illness and substance abuse including drinking and marijuana use. Experts from the University of York and the London School of Hygiene and Tropical Medicine (LSHTM) analysed all available reviews on youth vaping – also known as an umbrella review. This including 56 reviews on 384 studies. Some 21 of these looked at use of e-cigarettes among young people and later cigarette smoking. Not only were vapers more likely to smoke in later life, they were also more likely to smoke more frequently and intensely, experts said. Researchers also tracked breathing problems linked to youth vaping. The data suggested an increased risk among young people who vape of developing asthma or asthma exacerbation. Other harmful outcomes linked to youth vaping included pneumonia, bronchitis, lower total sperm counts,dizziness, headaches and migraines. There was also a link identified between depression and suicidal thoughts among young vapers. Writing in the journal Tobacco Control, the authors said the data available 'consistently indicated a significant association between e-cigarette use and later cigarette smoking in young people'. They said that it is difficult to 'infer causality' from their review, but said the 'repeated strong associations in prospective cohort studies are consistent with a causal relationship'. Dr Su Golder, associate professor in health science at the University of York, said: 'The consistency in the evidence is striking. 'Across multiple studies, young people who use e-cigarettes are more likely to smoke in the future. These findings support stronger public health measures to protect teens from the risks associated with vaping.' Dr Greg Hartwell, clinical assistant professor at LSHTM, said: 'We found consistent evidence around transitions to smoking which of course, in turn, opens the door to the multitude of harms that conventional cigarettes bring. 'As the UK Government's chief medical officer states, marketing vapes to children is always unacceptable, and our review shows exactly why further restrictions on the tobacco industry, who control the vaping market, are so important.' Dr Rebecca Glover, senior author of the study, assistant professor at LSHTM, added: 'Vaping is having a detrimental impact on the health of young people globally and vaping appears to be a gateway to other substances. 'Our study provides the strongest evidence to date that young people globally face a serious range of physical and psychological harms from vaping and are at higher risk of transitioning to smoking.' In June the ban on disposable vapes was introduced in a bid to curb their use among young people. The crackdown on the devices, also known as single-use vapes, makes it illegal for any retailer – ranging from corner shops to supermarkets – to sell them. The ban applies to both online and in-store sales across England, Scotland, Wales and Northern Ireland, and all disposable vapes whether or not they contain nicotine. Retailers are still allowed to sell reusable vapes. Commenting on the study, Jamie Strachan, operations director at VPZ, said: 'Vaping is intended solely for existing adult smokers as a less harmful alternative to combustible tobacco. It should never be marketed to, sold to, or used by children and non-smokers. 'VPZ supports strict regulation that prevents under-18s from obtaining vaping products.' Dr James Murphy, director of science and research at British American Tobacco (BAT), said: 'There is little evidence that vaping is a gateway to smoking. In fact, it has helped millions of adults move away from cigarettes. 'While not risk-free, experts agree it poses only a fraction of the risks of smoking. 'Smart regulation that gives adults access to better alternatives, while enforcing high standards and preventing under-age use, is vital to achieving the UK's smoke-free goal.'

Major study uncovers health risks of vaping for young people
A new study has revealed the health risks associated with children who vape. Children who engage in vaping are more likely to go on to be smokers, be diagnosed with asthma and have poor mental health.

Young vape users three times as likely to start smoking, study finds
Young people who vape are three times as likely to start smoking, develop asthma and have poor mental health as those who do not, according to a study that lays bare the health impacts of e-cigarettes. Vaping among young people is consistently linked to later smoking, according to the largest umbrella review of all the evidence on youth vaping, which warns that e-cigarettes could act as a gateway. The researchers found associations with other harmful consequences including asthma, cough, injuries and mental ill health, as well as possible risks of respiratory disease, headaches, poor oral health and substance use. Su Golder, an associate professor in health science at the University of York and an author of the research, said: 'The consistency in the evidence is striking. Across multiple studies, young people who use e-cigarettes are more likely to smoke in the future. These findings support stronger public health measures to protect teens from the risks associated with vaping.' The researchers concluded that although it was not yet possible to definitively say vaping leads children to smoke, precautionary policies to restrict sales and marketing of vapes to young people were needed. Dr Ronny Cheung, of the Royal College of Paediatrics, said the study 'adds to the mounting evidence that youth vaping is a serious threat to health and wellbeing, with strong links to smoking and other harmful behaviours'. Cheung urged the government not to further delay implementing the tobacco and vapes bill, which will limit the flavours, packaging and marketing of vapes. The World Health Organization (WHO) has previously described the rise in children vaping around the world as alarming. Figures compiled by Action on Smoking and Health this year showed that 20% of 11- to 17-year-olds in Great Britain had tried vaping, amounting to an estimated 1.1 million children, triple the levels in 2020. For the new study, which was published in the journal Tobacco Control, researchers examined 56 reviews, most of which suggested that young people who vape are about three times as likely to start smoking as those who do not vape. Asthma was the most common respiratory health condition, with consistent associations of between 20% and 36% increased risk of being diagnosed with the condition, and a 44% risk of worsening symptoms. The researchers acknowledged that the umbrella reviews were of variable quality and that it was difficult to prove a causal relationship since the evidence was mostly observational. They urged further research to better understand whether vapes are genuinely acting as a gateway to smoking. Last month, researchers at the University of Michigan established that a third of UK teenagers who vape will go on to start smoking tobacco, meaning they are as likely to smoke as their peers in the 1970s were. Hazel Cheeseman, the chief executive of Action on Smoking and Health, said: 'The rise in teen vaping in recent years is very concerning and needs urgent action from government. Vapes are effective quit aids for adults who smoke and while they are less harmful than smoking, they are not risk free and should not be used by children.' Dr Stephen Burgess, a statistician at the University of Cambridge, said the research showed 'that vaping users are more likely to engage in certain behaviours, but whether vaping is truly a cause of these behaviours is beyond the scope of the data'. He added: 'The associations demonstrated are both extensive in scope and strong in magnitude – it is clear that vaping users are at higher risk of many diseases than non-users. A causal explanation to the findings is both plausible and consistent with the evidence provided but such a finding can only be made conclusively by a randomised trial. Ann McNeill, a professor of tobacco addiction at King's College London, noted that many of the studies on which the researchers drew for the study were 'rated critically low or low quality, meaning authors should be extremely cautious before making any conclusions'. She said there could be other reasons for the consistency of the relationship between vaping and cigarette smoking – for example, a young person having a sensation-seeking or impulsive personality. Other research looking at population-level trends in vaping and smoking had found that as youth vaping increased in a population, smoking reduced, she said. John Dunne, UK Vaping Industry Association director general, said: 'We have seen a lot of research from the scientific community about vaping which does not stand up to scrutiny and this latest study seems to fit the bill. 'We need to stop demonising vaping because until the relative risks of cigarettes and vaping are understood by smokers then 220 people will needlessly die in the UK of smoking-related illnesses every day.' A Department of Health and Social Care spokesperson said: 'Our health advice is clear, while vapes are less harmful than smoking and can be an effective quit aid for smokers, children and non-smokers should never vape. 'The worrying rise in youth vaping requires attention – that's why we commissioned this research, the largest comprehensive review of the health impacts of youth vaping to date. 'We are taking decisive action through the landmark tobacco and vapes bill and single-use vape ban, which will put an end to the cycle of addiction and stop the next generation getting hooked on nicotine.'
