Nightjar numbers tracked in major heathland bird survey
"I absolutely love a nightjar. They are by far my favourite bird," says Mya Bambrick, Youth Representative with the British Trust for Ornithology.We are standing in the middle of nowhere on heathland in the north of the New Forest. The light is fading fast and we have set off in search of the nightjar."They're such a unique species that we have here in the UK," Mya says."They are corpuscular, hence why we're out here at this time, so they're active at dusk and dawn."And they make an absolutely fascinating sound."They are also experts at camouflage and only active in poor light, so trying to spot one, let along film one, is going to prove a challenge. But while the nightjar can be hard to see, its strange call is instantly recognisable.
"The males make what we call a churr," explains Mya."Almost like an insect. I would say there's nothing else that looks and sounds like a Nightjar."Mya encourages me to cup my ears as we both scan the horizons for the first sounds and glimpses of the bird. A faint insect-like noise gradually starts to drift across the heath, before a sharp "peep" of a flight call rings out.Mya excitedly points behind me as I spin round to catch my first glimpse of one."Flying now - flying just above the tree line to the right of that big tree."
It is not long before we see the distinctive silhouettes of nightjars, with their pointed wings and long tails, circling above.At one point two males dart after a female disappearing in and out of trees on the edge of the heathland.The faint churring has increased in volume, with flight calls ringing out around us."You can see why they're my favourite bird - I mean they're absolutely stunning," Mya says."We've had all the vocalisations. We had the churring, we had the 'kwik, kwik' flight call. "And then we also had that whirring down call, so we know there's a female definitely on a nest very nearby."
In 2004 the Nightjar population was recorded as 4,600 territories across the UK. This year's survey hopes to confirm anecdotal evidence of increasing numbers.While continued conservation work to restore heathland has undoubtedly had a positive effect, the decline of our insect population may be a factor in the future.In the meantime this is one bird that has just gained another fan.

Tool could help improve your fitness in just 30 minutes
An early trial suggests a small device that stimulates a major nerve connecting the heart and brain could help improve fitness. The device, clipped to the outer ear, sends gentle electrical pulses to increase the activity of the vagus nerve, which regulates heart function. Wearing the stimulator for just 30 minutes a day for a week increased oxygen intake during exercise by 4 per cent in healthy volunteers. The study, led by researchers at University College London and Queen Mary University of London, involved 28 healthy volunteers and was published in the European Heart Journal. While larger trials are needed, researchers hope the device could one day be used to improve fitness, reduce inflammation, and potentially aid people with heart conditions.

Scientists discover remarkable health impact of a daily 'fast walk'
Hitting 10,000 steps a day is a goal for millions of us—but we should be focusing on the pace not the paces, according to a new study. Research suggests that going on a daily brisk 15-minute walk could boost heart health and reduce risk of death by 19 per cent. US researchers, who studied more than 79,850 adults from low-income areas, found that a short brisk walk was more beneficial than walking at a slower pace for three hours, even when overall leisure-time physical activity levels were accounted for. Experts argued that the findings show that walking, particularly at a brisk pace, is an effective form of exercise—especially for those in low income areas— that could protect against heart disease. It comes as alarming data released last year revealed that premature deaths from cardiovascular problems, such as heart attacks and strokes, had hit their highest level in more than a decade. In the UK, around 420 people of working age die of as a result of heart disease each week, which works out as 21,975 people a year. In the current study, which analysed data from the Southern Community Cohort Study between 2002 and 2009, participants reported how many minutes they spent per day engaging in walking slowly and walking fast. Walking at work, engaging in light exercise or walking the dog were classed as 'walking slowly', whereas more dynamic activities such as climbing the stairs, brisk walking and exercise were considered fast. Over a follow-up of just under 17 years, the researchers discovered that walking fast for as little as 15 minutes per day reduced the risk of all cause mortality by nearly 20 per cent. Writing in the American Journal of Preventive Medicine, they found the effect was most pronounced for cardiovascular disease. According to Professor Wei Zeng, lead investigator and expert in lifestyle factors and diseases, fast walking could reduce cardiovascular mortality by improving how efficiently the heart works and reducing obesity. This style of exercise has previously been shown to increase VO2-max —a measure of how much oxygen the body can process during exercise. A high VO2 max is associated with better physical fitness and lower risk of cardiovascular disease, indicating that the body is efficiently extracting and using oxygen from the blood. Prof Zeng concluded: 'Brisk walking offers a convenient, accessible and low-impact activity that individuals of all ages and fitness levels can use to improve general health and cardiovascular health specifically.' The experts, lead by Professor Lili Liu, lead author and trainee epidemiologist, are now urging health officials to encourage fast walking within all communities—especially those with limited access to healthcare—and address barriers to daily walking such as safety concerns. They added: 'Public health campaigns and community-based programmes can emphasise the importance and availability of fast walking to improve health outcomes. NHS data shows a rise in the number of younger adults suffering from heart attacks over the past decade. The biggest increase (95 per cent) was recorded in the 25-29 year-old demographic, though as numbers of patients are low even small spikes can look dramatic 'Individuals should strive to incorporate more intense physical activity into their routines, such as brisk walking or other forms of aerobic exercise.' The scientists, however, acknowledged that because physical activity data was only collected at the beginning of the study, changes in activity levels could not be considered. The paper also had some limitations, they said, including the fact daily walking levels were self-reported. Sedentary lifestyles in the UK, with Brits spending their workhours deskbound, then sitting in a train or car on their way home to sit down in front of the TV, have been estimated to kill thousands each year. The WHO puts the annual global death toll from physical inactivity at around 2million per year, making it in the running to be among the top 10 leading causes of global death and disability. Physical inactivity has been long linked to health problems like cardiovascular disease as well contributing to health problems like obesity, itself linked to an increased risk of type 2 diabetes and some cancers. Cases of heart attacks, heart failure and strokes among the under-75s had tumbled since the 1960s thanks to plummeting smoking rates, advanced surgical techniques and breakthroughs such as stents and statins. But now, other factors such as slow ambulance response times for category 2 calls in England — which includes suspected heart attacks and strokes — as well as long waits for tests and treatment have also been blamed.

Government study to check pet dog and cat poo for superbugs
The UK government will soon be asking lots of cat and dog owners to collect and send their pet's poo for laboratory testing. Experts worry that some domestic animals might carry hard-to-treat superbugs - bacteria that have become resistant to common antibiotics. These can spread to people through close contact with pets, such as kissing and stroking, as well as handling poo, research many cases the bacteria do no harm, but some can lead to serious issues, including bloodstream infections or world-first study will monitor healthy pets, not just those that are ill. Poo samples Over half of UK adults own pets and live with them in a shared environment, meaning that bacteria, including resistant bacteria, can spread easily between animals and people, says the goverment's Veterinary Medicines studies have shown pets and owners can potentially swap pathogens, including the hospital 'superbug' Royal College will run the study over four years. Prof John Berezowski, who is one of the researchers, said they would work with pet owners and their vets to explore how best to collect all the poo samples."This initiative is critical for a better understanding of the transmission and maintenance of antimicrobial resistance in our pets," he said. The World Health Organization classes antibiotic resistance as one of the greatest public health threats facing humanity. Drug-resistant infections kill more than 1.2 million people a year globally, with the figure projected to rise to 10 million by 2050 if no action is taken, it says. To prevent transmission, experts recommend owners practise good hygiene, including washing their hands after petting their dog or cat and after handling their a pet is unwell, owners might consider isolating them in one room to prevent the spread of bacteria throughout the house, and clean other rooms thoroughly. Antimicrobial resistance (AMR) arises when organisms that cause infection evolve ways to survive effective antibiotics, even minor surgery and routine operations, such as caesarean sections when giving birth, could become high-risk procedures if serious infections can't be treated.
