Siamese crocodile hatchlings reunited with parents in zoo
The newest arrivals have not been named yet and have been sitting out basking, then "swimming over and sitting on mum or dad's back," he said.Mr Stevenson, originally from Sydney Australia, said: "It's a bit of a surprise to a lot of people that crocs are such good parents."They're the only reptiles that show extended and quite detailed parental care."It is "excellent" from an education point of view, he said, as the team was able to monitor the crocodiles' parent and child relationship in action.
"Both mum and dad are extremely protective of the young ones," he said, which made feeding and maintaining the enclosures "tricky" for the keepers."The parents are extra sensitive at the moment because they're in protective mode and everything can be seen as a threat to the hatchlings," Mr Stevenson said.The animals, which can live into their 50s, usually grow to around 6,000 times their birth size.They are native to Indonesia, Laos, Cambodia, Thailand and Vietnam and are considered critically endangered by the International Union for Conservation of Nature.They were near to extinction but have been making a comeback in some areas.

Cats develop dementia in a similar way to humans
Cats develop dementia in a similar way to humans with Alzheimer's disease, leading to hopes of a breakthrough in research, according to scientists. Experts at the University of Edinburgh carried out a post-mortem brain examination on 25 cats which had symptoms of dementia in life, including confusion, sleep disruption and an increase in vocalisation. They found a build-up of amyloid-beta, a toxic protein and one of the defining features of Alzheimer's disease. The discovery has been hailed as a "perfect natural model for Alzheimer's" by scientists who believe it will help them explore new treatments for humans. Dr Robert McGeachan, study lead from the University of Edinburgh's Royal (Dick) School of Veterinary Studies, said: "Dementia is a devastating disease - whether it affects humans, cats, or dogs. "Our findings highlight the striking similarities between feline dementia and Alzheimer's disease in people. "This opens the door to exploring whether promising new treatments for human Alzheimer's disease could also help our ageing pets. Microscopy images of older cats which had previously shown symptoms of feline dementia revealed a build-up of amyloid-beta within the synapses - the junctions of brain cells. Synapses allow the flow of messages between brain cells, and losing these causes reduced memory and thinking abilities in humans with Alzheimer's. The team believe the discovery in cats could help them get a clearer understanding of the process, offering a valuable model for studying dementia in people. Previously, researchers have studied genetically-modified rodents, although the species does not naturally suffer from dementia. "Because cats naturally develop these brain changes, they may also offer a more accurate model of the disease than traditional laboratory animals, ultimately benefiting both species and their caregivers," Dr McGeachan said. Will this research benefit cats? The researchers found evidence that brain support cells - called astrocytes and microglia - engulfed the affected synapses. It's known as synaptic pruning, an important process during brain development but which contributes to dementia. Prof Danielle Gunn-Moore, an expert in feline medicine at the vet school, said the discovery could also help to understand and manage feline dementia. "Feline dementia is so distressing for the cat and for its person," she said. "It is by undertaking studies like this that we will understand how best to treat them. This will be wonderful for the cats, their owners, people with Alzheimer's and their loved ones." The animal rights campaign group People for the Ethical Treatment of Animals said the study appeared to have been conducted in a "respectful, non-invasive way" on the brain of cats that already died. However it said it would oppose any research that involved future experiments on live cats. The study, funded by Wellcome and the UK Dementia Research Institute, is published in the European Journal of Neuroscience, and included scientists from the Universities of Edinburgh and California, UK Dementia Research Institute and Scottish Brain Sciences.

Struggling to sleep? Your gut bacteria could be to blame
Your gut health can impact everything from your mood to your immune system, but it could also be the cause of your poor sleep, a study has found. Specific types of gut bacteria have been linked to insomnia risk by researchers, while insomnia itself has also been linked to an abundance of certain 'bugs' in the gut. Insomnia, which means a person has difficulty falling and staying asleep, affects about a third of adults in the UK. It can be caused by anxiety, noise, alcohol, caffeine or shift work, according to the NHS. Several studies have explored the effects of the gut microbiome on various sleep characteristics, but it's not yet clear how different groups of gut bacteria might affect the risk of insomnia. The study, published in the journal General Psychiatry, used data on 386,533 people with insomnia from a previously study, gut microbiome data for 18,340 people from the MiBioGen alliance and for 8,208 people from the Dutch Microbiome Project with 71 groups of bacteria in common. Their analysis revealed associations between specific gut microbes and insomnia. Overall, a total of 14 groups of bacteria were positively associated with insomnia and eight groups showed a negative association. Insomnia itself was associated with a reduction of between 43 per cent and 79 per cent in the abundance of seven groups of bacteria and a 65 per cent to a more than fourfold increase in the abundance of 12 other groups. Researchers found the Odoribacter class of bacteria, in particular, was significantly associated with the risk of insomnia. This type of bacteria plays a role in producing short-chain fatty acids like butyrate, which in the right levels can help maintain a healthy gut. However, there are some limitations to the study. All the study participants were of European descent, so the results may not be more widely applicable as the make-up of the microbiome varies among different ethnicities and geographies, researchers point out. Diet and lifestyle – which affect the microbiome – were also not accounted for. Although bacteria are linked to insomnia, those same bacteria may be shaped by a person's eating habits, stress levels, and environment. 'Overall, the intertwined effects of insomnia on gut microbiota, and vice versa, represent a complex bidirectional relationship involving immune regulation, inflammatory response, release of neurotransmitters, and other molecular and cellular pathways,' study authors said. The authors conclude: 'Our study offers preliminary evidence supporting a causal effect between insomnia and gut microbiota, providing valuable insights for the future development of microbiome-inspired treatment plans for insomnia.' These treatment plans might include the use of probiotics, prebiotics, or faecal microbiota transplantation, they suggest.

Scientists make microplastic discovery in hot drinks
New research suggests hot drinks may be a more significant source of microplastics than previously realised. A University of Birmingham study found the highest concentrations of microplastics in hot tea and hot coffee among 155 common drinks tested. The research indicates that high temperatures and preparation processes for hot beverages contribute to increased microplastic levels. Hot tea in disposable cups contained the most microplastics, averaging 22 particles per cup, with more expensive teabags also leaching substantial amounts. The findings suggest that assessing microplastic exposure solely through drinking water may underestimate the overall risk, calling for more comprehensive dietary studies.
