Mosquito colony feeds on blood from scientist's arm
Dr Véronique Paris has a hands-on approach to her research — she lets hundreds of mosquitoes bite her arm in order to feed and maintain her mosquito lab. Paris helps research mosquito-borne diseases. 'We have people working on mosquitoes here that don't feed their own colonies, there will always be volunteers around that can do that, so no one has to feed mosquitos if they don't want to and that's totally fine," Paris says

GPs can prescribe weight loss jabs on the NHS from today - but strict eligibility criteria in place
Why you can trust Sky News GPs will be able to prescribe weight loss jabs on the NHS from today. - with strict criteria for the first year of the rollout. Initially, only those with a body mass index of over 40 who have at least four other health problems linked to obesity will be eligible. 0:21 Some doctors have raised concerns about the additional workload this new programme will bring, while pharmacists fear it could lead to supply shortages. While an estimated 1.5 million people are now taking weight loss drugs across the UK, they could previously only be accessed through specialist services or private prescriptions. Dr Claire Fuller from NHS England said: "We urgently need to address rising levels of obesity and prioritise support for those who are experiencing severe ill health - and greater access to weight loss drugs will make a significant difference to the lives of those people." She added: "While not everyone will be eligible for weight loss drugs, it's important that anyone who is worried about the impact of their weight on their health discusses the range of NHS support available with their healthcare professional." 1:22 The chairwoman of the Royal College of GPs welcomed NHS England's decision to pursue a phased rollout, and said current workloads must be factored in to ensure the jabs can be prescribed safely. Professor Kamila Hawthorne went on to say: "While weight loss medications have a lot of potential benefits for patients who are struggling to lose weight and who meet all the clinical criteria for a prescription, they mustn't be seen as a 'silver bullet' to aid weight loss. "We also need to see a focus on prevention, stopping people becoming overweight in the first place so they don't require a medical intervention later." 9:19 Her remarks were echoed by the National Pharmacy Association's chairman Olivier Picard, who says "prescribing these medications alone misses the point". He argued that they need to be part of a comprehensive strategy that includes lifestyle coaching, exercise and nutritional guidance - but many GPs currently "lack the bandwidth" to provide this support. "As a result, we could end up in a situation where patients are prescribed the medication, lose weight, and then experience rebound weight gain once the course ends - simply because the foundational lifestyle changes weren't addressed," Mr Picard added. Estimates suggest about 29% of the adult population is obese.

Ukraine-Russia war live: Moscow's wartime toll hits grim milestone while massive drone attack injures five in Kyiv
Nearly one million Russian soldiers have been killed or injured in the Ukraine war, according to the British defence ministry and an American think tank. The defence ministry says over a million Russian soldiers have died or suffered injuries during the war, which started on 24 February 2022. The estimates align with a study by the American think tank Centre for Strategic and International Studies. The think tank estimates Russian deaths at around 250,000 and total casualties, including the wounded, at nearly 950,000, the Guardian reported. The Ukrainian death toll it puts at between 60,000 and 100,000 and total casualties up to 400,000. In continuing hostilities, an overnight Russian drone attack on Kyiv killed five civilians, sparked fires in residential areas and damaged an entrance to a metro station, Ukrainian authorities said on Monday.

Simple blood test capable of identifying if you will rapidly develop severe Alzheimer's
A simple blood test can tell which patients will rapidly develop severe Alzheimer's, a study reveals today. Identifying those with mild cognitive impairment who are most likely to suffer an accelerated decline could allow them to enter clinical trials and receive extra support, researchers say. Neurologists tested 315 non-diabetic patients with cognitive deficits, including 200 with Alzheimer's disease, for resistance to insulin – a hormone that regulates blood-sugar levels. This was assessed using the triglyceride-glucose (TyG) index. Among those with mild cognitive impairment due to Alzheimer's, individuals with the highest TyG scores declined four times faster over the three-year follow-up period than those with lower TyG levels. Researchers suggest that insulin resistance, which has already been linked to the onset of Alzheimer's, may accelerate progression by impairing the uptake of glucose in the brain, promotinginflammation and disrupting the blood-brain barrier. It may also contribute to the build-up of amyloid, a toxic protein, in the brains of Alzheimer's patients. The scientists at the University of Brescia, Italy, also found that high TyG was associated with blood-brain barrier disruption and cardiovascular risk factors. But they found no link between high TyG and other neurodegenerative diseases. Their study will be presented today at the European Academy of Neurology Congressin Helsinki. Lead researcher Dr Bianca Gumina said: 'Once mild cognitive impairment is diagnosed, families always ask how fast it will progress. 'Our data shows that a simple metabolic marker available in every hospital laboratorycan help identify more vulnerable subjects who may besuitable candidates for targeted therapy or specificintervention strategies.'
