Kittiwakes have died on Isle of May
A total of 148 of the birds have been counted dead from the disease on the Isle of May in the last few weeks.
Staff on the island, in the outer Firth of Forth, said the toll showed the highly pathogenic avian influenza (HPAI) virus 'is still very evident in seabird colonies'.
However, kittiwakes appear to be the only species affected this year on the island, which is run by NatureScot as a National Nature Reserve, with suggestions of immunity building in some other birds.
David Steel, NatureScot's reserve manager on the island, said: 'In recent years all seabird species have been affected by the virus including several on the island.
'However it appears more virulent in our kittiwakes as we have seen losses on an annual basis since 2022.
'Over the last few weeks we have noticed a number of kittiwakes dead on the loch and yesterday we confirmed a total of 148 dead, which had built up over a few weeks.'
Bird flu outbreak was first detected in great skuas in the Northern Isles in summer 2021 and in 2022 spread to seabirds across Scotland, with devastating impacts on some species. The virus spreads between birds through contact with infected saliva and droppings.
Known as the 'Jewel of the Forth', the Isle of May becomes home each spring to up to 200,000 birds including puffins, guillemots, razorbills, kittiwakes and shags.

Health Rounds: Virtual labs with AI scientists produce promising result in Stanford study
July 30 (Reuters) - (This is an excerpt of the Health Rounds newsletter, where we present latest medical studies on Tuesdays and Thursdays. To receive the full newsletter in your inbox for free sign up here.) Virtual scientists in a virtual lab at Stanford University are coming up with unorthodox ways to address clinical challenges, researchers reported on Tuesday in Nature, opens new tab. The virtual lab is modeled after a well-established Stanford School of Medicine research group, complete with a principal investigator and seasoned scientists, the report says. As in human-run research labs, the virtual lab has regular meetings during which agents generate ideas and engage in a conversational back-and-forth. They also have one-on-one meetings, allowing the virtual lab members to meet with the virtual principal investigator individually to discuss ideas. Unlike human meetings, the virtual gatherings take a few seconds or minutes. When humans tasked the virtual team with devising a better vaccine for the SARS-CoV-2 virus that causes COVID-19, they equipped the virtual scientists with tools and software to stimulate creative 'thinking' skills. The virtual scientists even created their own wish list. 'They would ask for access to certain tools, and we'd build it into the model to let them use it,' study leader James Zou said in a statement. Instead of opting for the usual vaccine design using an antibody, the AI team came up with using a nanobody, an antibody fragment that's smaller and simpler. 'From the beginning of their meetings, the AI scientists decided that nanobodies would be a more promising strategy,' Zou said. 'They said nanobodies are typically much smaller than antibodies, so that makes the machine learning scientist's job much easier," Zou said, "because when you computationally model proteins, working with smaller molecules means you can have more confidence in modeling and designing them.' When humans created the AI researchers' nanobody in a real-world lab, they found it was stable and could attach itself to one of the COVID virus variants more tightly than existing antibodies - a key factor in determining vaccine effectiveness. Aside from the initial prompt, the main guideline consistently given to the AI lab members was budget-related. Zou estimates that he or his lab members intervene about 1% of the time. 'I don't want to tell the AI scientists exactly how they should do their work. That really limits their creativity,' Zou said. 'I want them to come up with new solutions and ideas that are beyond what I would think about.' SCIENTISTS FIND GENES THAT CAUSE STUTTERING A new study found a clear genetic basis for stuttering, the speech disorder that affects more than 400 million people worldwide. Overall, as reported in Nature Genetics, opens new tab, the researchers identified 57 distinct regions on 48 genes associated with stuttering. Some of the same genetic variants involved in stuttering can also contribute to autism, depression and musicality, they found. Stuttering, characterized by syllable and word repetitions, sound prolongations, and breaks between words, is the most common fluency disorder, the researchers said. 'There have been hundreds of years of misconceptions about what causes stuttering, from ideas about left-handedness to childhood trauma to overbearing mothers,' study leader Jennifer (Piper) Below of Vanderbilt University Medical Center in Nashville said in a statement. 'Rather than being caused by personal or familial failings or intelligence, our study shows that stuttering is influenced by our genes.' Young people who stutter report increased bullying, decreased classroom participation, and a more negative educational experience, her team noted. Stuttering can also negatively impact employment opportunities and perceived job performance, as well as mental and social well-being. Dillon Pruett, a postdoctoral fellow at Vanderbilt and a co-author of the study, stutters. 'As someone personally affected, I wanted to contribute to this body of research,' he said. 'Our study found that there are many genes that ultimately contribute to stuttering risk, and we hope to use this knowledge to dispel stigma related to stuttering and also to hopefully develop new therapeutic approaches in the future.' AT THE SIGHT OF A SICK PERSON, THE BRAIN GOES ON ALERT At the mere sight of a possibly contagious person, the human brain launches its germ-fighting preparations, researchers say. In virtual reality experiments using Google's Oculus Rift headsets, 248 healthy young adults were approached by human-like avatars, some of which showed visible signs of infection, such as rashes or coughing. Other avatars appeared neutral or fearful. As the infectious avatars moved closer, noninvasive monitoring showed changes in brain regions involved in integrating awareness of the body's position, movement, and relationship to the surrounding environment, which was not seen in response to the approaching neutral or fearful faces, the researchers reported in Nature Neuroscience, opens new tab. Participants were more reactive to touch when the sick-looking avatars were nearby, the researchers also found. Blood samples showed that exposure to the infectious-appearing avatars triggered an increase in volunteers' innate lymphoid cell activity, a key component of the immune system, which is typically seen during responses to real infections or vaccines. The results illustrate the power of the brain 'to predict what is going on (and) to select the proper response,' study co-author Andrea Serino of University Hospital of Lausanne, Switzerland said in an accompanying news article, opens new tab in the journal. The researchers said that someday, virtual reality might be employed to boost the efficacy of vaccines by boosting the brain's effect on immune responses.

Sight of someone potentially infectious causes immune response, research suggests
Whether it's the person brandishing a tissue on the train or the child with the telltale signs of chickenpox, the threat of an infection can be enough for us to beat a retreat. Now researchers using virtual reality avatars have shown that the mere sight of a potentially contagious person is enough to mobilise our immune system too. 'Although surprising, our finding that immune responses can be triggered by simulated infections presented in VR is consistent with the principle of the smoke detector in biological systems,' the authors said, adding the behavioural system that helps us avoid catching diseases is 'exquisitely sensitive' to cues that may suggest someone is sick. Writing in the journal Nature Neuroscience, the researchers reported how they fitted 248 healthy people with VR headsets and carried out five experiments, each involving a minimum of 32 participants. In each experiment, participants initially watched three faces of the same sex as themselves repeatedly loom towards them, bearing a neutral expression. Participants were then split into groups and shown the same three faces multiple times, either with a neutral expression or signs of viral infections such as skin rashes. In some experiments, an additional subset of participants were shown the faces displaying an expression of fear. In one experiment, participants were asked to press a button as fast as possible after receiving a mild touch to their face while an avatar was shown. The team found that when the avatars showed signs of sickness, participants pressed the button when the faces appeared further away than for faces showing a neutral or fearful expression. Results from EEG tests to investigate the electrical activity of the brain tallied with these findings. As expected, as avatars loomed closer, the brain system that represents the space closely surrounding our body became activated. However, this activation differed when the avatars showed signs of infection compared with neutral expressions, even when they appeared far away. These differences, the team add, were localised in areas of the brain involved in detecting and filtering threats. The team found that functional MRI (fMRI) brain scans supported these results, further revealing that when infectious avatars were shown there was a greater connection between this threat-detection network and part of the brain called the hypothalamus, which acts as a key regulation centre for the body. The team also found differences in participants' blood when they were shown the infectious avatars compared with neutral or fearful faces. '[In terms of cells], we saw mainly that there is an activation of an immune cell family called the innate lymphoid cells (ILCs)that [are] early responders in immunity to basically alarm other immune cells,' said Prof Camilla Jandus of the University of Geneva and an author of the study. The team added that they found a similar activation of ILCs when they examined the blood of individuals who had received an influenza vaccine but had not been exposed to the VR setup. Dr Esther Diekhof of the University of Hamburg, who was not involved in the work, said the study chimed with previous research, including that of her own team. 'The study provides yet another good example for the existence of a mechanism that responds to potential contagion threats even before the immune system has come into contact with pathogens,' she said. But Prof Benedict Seddon, of University College London, said questions remained, including whether the observed responses help the immune system actually fight an infection. 'When we get infected, by Sars-CoV for instance, it can take a day or two for the infection to establish and for the immune system to become aware of it and respond, a long time after the initial encounter that stimulated this short-lived mobilisation,' he said.

Leek fly-tipped wasteland turned into community garden
A frustrated gardener was so riled by a dirty and inaccessible plot of land in his town centre, that he stripped the site and helped turn it into a community Collingwood was looking for a project after being diagnosed with leukaemia and, being a passionate nature enthusiast, wanted to attract wildlife to a forgotten area of Leek in clearing the mess, he was joined by like-minded gardener Jack Laverick, who planted beds and flowers to create a "secret garden"."It's a piece of long neglected land which we've converted from a complete disaster into a garden," said Mr Collingwood. "We're a good team," he said, pointing to Mr Laverick, "I'm the destroyer and he's the creator." The patch of land is accessible via a graffitied and littered alleyway just off Haywood Street, the main access road through the Staffordshire Moorlands used to be the site of a workshop, warehouse and cottages, which decayed and were eventually fly-tippers threw old mattresses, oil drums and plastic bags filled with rubbish into the thick foliage, making the area inaccessible and unpleasant. "I think a lot of people, particularly women, didn't like to walk down this alleyway, because they felt rather threatened by it," Mr Collingwood said."It was such a mess on this piece of land."In February 2024, Mr Collingwood started a new regime of chemotherapy and was looking for an activity to take his mind off his condition."This used to irritate me so much that I just decided that I needed a project to get stuck into," he said. After clearing the site, Mr Collingwood went on holiday and on his return unexpectedly found Mr Laverick had started planting."I'd seen other people doing similar things online, trying to clear up fly-tipped areas and alleyways in Manchester," Mr Laverick said."They were using plants and gardens as a way to keep rubbish from coming back.""I'd seen what Neil was doing and I thought it could be great for that."Recycling is also an important aspect of the gardening pair have repurposed filing cabinets, trampoline pieces and a bath to create flower beds, an archway and a bird bath."Lots of people are wandering in, sitting down, having lunch, just appreciating the plants, learning about nature," Mr Laverick said."People are really enjoying it."Those people include Leek town councillors, who have visited the site and think it is an excellent idea to use the space for an urban garden.
