Witney smoking shelter used for research after bird's nest discovery
A smoking shelter has become the centre of a scientific study after a chance discovery of a bird's nest in one of the smoking bins.Joanne Olsen from the electronic manufacturer HYDAC Technology based in Windrush Park in Witney, Oxfordshire, opened the bin to find the great tit nest and eggs.Douglas Russell, senior curator for birds' eggs and nests at the Natural History Museum (NHM) in Tring, Hertfordshire, said scientists thought birds were choosing cigarette ends as materials to add to nests "because it decreases parasite load" as the nicotine "kills parasites".The closely-monitored nest will be collected for chemical analysis by the NHM team after the chicks have left it.
Ms Olsen said her colleague had thought there had been a frog at the smoking point at first because it had jumped up."So I went and retrieved the key, opened the back and there was a nest with eggs inside."Ms Olsen reported the nest to the RSPB who in turn contacted the team behind the study. George Candelin, keeper of the swifts at the University of Oxford Museum of Natural History, has been monitoring the temperatures inside and outside of the metal container with Ms Olsen's help."We've had temperatures up in the high 30s, the perspex itself on one occasion was over 40C," he said.He added he was "amazed" that the birds had been "so comfortable with people so close". "We only go in the shelter for a few minutes to take the readings but you can stand over in the corner there and you'll see the birds coming in and out totally unaffected by it."
Mr Russell said it was "a wonderful opportunity" to study the behaviour."We also know that birds pick up cigarette ends and incorporate them into nests," he said."And we think that birds are choosing those cigarette ends a materials to add to nests because it decreases parasite load because the nicotine kills parasites."But Mr Russell also previously said there were more than 7,000 chemicals found in cigarettes and smoke, including some 80 chemicals known to cause cancer."You're sucking in all those horrible compounds that are associated with cigarette smoke but you're also drawing in the road pollutants as well."And those are then getting concentrated within the bin, so either way it is a highly toxic, highly awful environment in which to bring up your young."
Currently, the brood seems to be thriving, with 10 of the twelve eggs already hatched.The chicks, which have been ringed under license, look set to leave the nest in the coming days. Mr Russell said the research aimed to draw attention to the widespread behaviour and to "try to understand what the chemical exposure to those young within that particular nesting environment is"."But I think the real positive from this is what it shows you is we need to put up more nest boxes," he said."If you put up more nest boxes even in these urban environments, the birds will use them."

First cases of Covid variant NB.1.8.1 detected in England as virus spreads across UK
The first cases of a new Covid-19 variant have been detected in England as the virus spreads across Britain, the UK 's health agency has confirmed The UK Health Security Agency (UKHSA) said 13 cases of Covid strain NB.1.8.1 had been recorded in England, with 'small numbers' detected across the UK. It's unclear how many cases of the new strain, which now account for just over 10 per cent of global infections, have been recorded in Scotland, Wales or Northern Ireland. Since first being recognised in January 2025, the omicron variant has spread to several states across the US, Australia, Thailand and is the most dominant variant in China and Hong Kong. UKHSA deputy director Dr Gayatri Amirthalingam said it was unlikely to pose more severe disease than other variants. Common symptoms align with typical Omicron subvariants and include fatigue, fever, muscle aches and a sore throat, according to the World Health Organisation. But given the dwindling number of people testing for Covid-19, it has become increasingly difficult to know the true number of infections. The World Health Organisation has designated the NB.1.8.1 as a 'variant under monitoring', and comprises around 10.7 per cent of all submitted sequences worldwide. While it first appeared in samples at the beginning of this year, data from GISAID, a global data of genetic sequences of major disease-causing viruses, show that the first known cases were registered at the end of April. Current Covid jabs are expected to remain effective against this variant and protect anyone infected from severe illness. Dr Gayatri Amirthalingam, UKHSA deputy director, told The Independent: 'It is normal for viruses to mutate and change over time. UKHSA is monitoring all available data relating to SARS-CoV-2 variants in the UK and abroad, and we continue to publish our findings in our regular Flu and COVID-19 surveillance reports. 'NB.1.8.1 has been detected in small numbers in the UK to date, but international data suggests that it is growing as a proportion of all COVID-19 cases. 'Based on the available information so far however, there is no evidence to suggest that this variant causes more severe disease than previous variants, or that the vaccines in current use will be less effective against it.'

How weight loss injections dey affect pregnancy and contraceptives?
Di UK medicines regulator don warn women wey dey use weight loss injections say make dem find beta contraception use.

Di thinking be say di side effects of dis medication wey be vomiting and diarrhoea and di fact say dem dey slow down di way belle dey take empty mean say di contraceptive medicine fit no enta bodi well. Di MHRA say women suppose use contraceptive togeda wit GLP-1 medicines and for a certain period afterwards before dem try to get belle - two months for Wegovy and Ozempic, and one month for Mounjaro. Dem also advice say pesin wey dey use Mounjaro and oral contraceptives get two options. Either dem go follow di contraception wit condoms for four weeks afta dem start di injection or else make dem change contraception go coil or implant. Advice for di use of contraception alreadi dey di leaflet wey dey follow di medicine but MHRA don issue dia own guidance join. Di drugs safety board say make pesin no take di weight-loss injections if: Dem suppose dey give women dis informate wen dem start to dey collect di injections, but worry dey say di warning no dey enta well. Natasha Major, 26, start to use Mounjaro to lose weight bifor she plan to born her third pikin in a few years. But e shock am as just six weeks later, she find out say, she don carry belle. She bin dey take contraceptive pill dat time. She tok say, "I get polycystic ovaries too, so I no dey quick-quick get belle like dat. So e even shock me pass say e easy to carry belle like dat, bicos e no make sense to me." She den start to dey worry about weda she go harm her pikin or weda di baby no go grow well.

Natasha add say, "I bin do early scan to make sure say di belle make sense and e dey okay, baby bin get small heartbeat and evritin dey good". Di MHRA and doctors and pharmacists dey worry say dem no dey use di popular GLP-1 medicine like Wegovy, Mounjaro, Saxenda, Victoza and Ozempic, safely. Dis prescription medicines dey licensed to treat obesity (and type 2 diabetes for Ozempic). E dey make pipo to feel full by acting as di hormone wey bodi dey release afta pesin don chop. Mounjaro dey also work wit anoda hormone wey dey linked to appetite and blood sugar control. Normally, na pipo wey get very high BMI, na im NHS dey give di drugs but pipo fit buy am for chemists. E don popular sotay dem don dey sell am illegally for social media and for beauty saons witout medical advice as sharp-sharp way to lose weight. Di MHRA dey advise pipo make dem follow di prescriber tok about di risks and benefits of taking dem, and understand di potential side-effects by talking to a doctor or pharmacist. E don act now because e don receive around 40 reports relating to pregnancy wey dem make to im Yellow Card scheme, wia di public fit report suspected side-effects of medicines. Some of dis be pregnancies wey hapun by mistake. Di chief safety officer for di MHRA, Dr Allison Cave tok say dem find evidence for animal studies say, "dis medicine dem fit harm unborn pikin. But we no know weda e go get di same effect for human beings, we need more data for dat one". Dem no use women wey dey child bearing age do dis clinical trial and na why safety information no dey for dem. Dr Cave say if pesin get belle and dem dey take di medicine, make dem follow dia doctor tok on how to stop am as soon as possible. Di vice chairwoman for di National Pharmacy Association, Sukhi Basra tok say make women go pharmacist for advice if dem dey confused as to wen dem suppose to stop to dey take di drugs. Dr Bassel Wattar wey be sabi pesin on pregnancy and consultant for Epsom and St Helier University Hospitals, say di implant or intrauterine coil na "more ogbonge contraception" dan oral combined contraceptive pill while pesin dey take di injections. For some women, to lose plenti weight fit help some women to get back dia natural ovulation and boost dia chance to get belle but e tok say dis kain tin, need planning safely wit specialist doctors "so di pregnancy go dey safe afta washout period of dis drugs". Di British Pregnancy Advisory Service, tok say women for UK, dey face ogbonge challenges wen dem dey try access dia contraceptive method of choice. Lack of appointments, long waiting lists and high costs na just some of di kasala dem dey face, according to di BPAS. Dis na as dem dey ask for beta plan to provide dis choices dem for women.

Weight loss jabs - what else don't we know?
👉 Listen to Sky News Daily on your podcast app 👈 The government's health agency, the MHRA, is warning women that they shouldn't use weight loss jabs while pregnant and that the drugs can also affect the reliability of the pill, which has led to a rise in so-called "Ozempic babies". On today's Sky News Daily Niall Paterson talks to Dr Nikita Kanani, a GP and former medical director for primary care at NHS England, about the risks, whether there are other concerns about using them and if there should be tighter restrictions on online sales of the jabs.
