Seagull after your chips? Fear the squadron, not the lone wolf
You settle down on the promenade to enjoy a bag of chips by the seaside. But then you realise you have been spotted. A single seagull is watching you eat with a hungry stare. Should you be afraid?
In an important discovery for those hoping to defend their lunch from greedy gulls, scientists have found that lone seagulls are usually reluctant to attack on their own, displaying a fear of approaching something unfamiliar.
This all changes, however, once they have strength in numbers.
Buoyed by a squadron of companions, gulls in a group are prepared to take greater risks to get food, a study has found. This may include dive-bombing an unsuspecting human to steal their battered cod and a handful of chips.

Bad news for hairy hipsters as scientists warn men with beards carry more germs than dogs
Hairy hipsters have received some shocking news as scientists have revealed men with beards carry more germs than dogs. Hollywood heartthrobs including Jason Momoa and Zayn Malik are known for their luxuriant facial hair, but a new report may make clean-shaven men more attractive. An expert revealed beards provide a unique environment for bacteria to thrive, and in extreme cases hirsute guys carry more germs than the average toilet. SCROLL DOWN FOR VIDEO Dr Primrose Freestone, an expert in clinical microbiology at the University of Leicester, in England, explained the findings in an article for The Conversation. She said: 'Beards create a warm, often moist environment where food debris and oils can accumulate – ideal conditions for microbial growth. 'These microbes thrive not just because of the warm, moist conditions beards provide, but also because of constant exposure to new contaminants and microbes, especially from hands that frequently touch surfaces and the face.' Studies dating back 50 years show that facial hair can retain bacteria and bacterial toxins even after it has been washed. This led to the longstanding idea that beards harbor bacteria and could pose an infection risk to others. One study, published in 2018, looked at whether it would be hygienic to evaluate dogs and humans in the same MRI scanner. Analysis revealed most beards contained significantly more microbes than dog fur – including a greater number of harmful bacteria. The study, published in the Nature journal European Radiology, said: 'Our study shows a significantly higher bacterial load in specimens taken from men's beards compared with dogs' fur. 'All 18 men showed high microbial counts, whereas only 23 out of 30 dogs had high microbial counts and seven dogs moderate microbial counts.' Beards can also sometimes spread skin infections such as impetigo – a contagious rash often caused by Staphylococcus aureus, which is commonly found in facial hair. Sometimes, in rare cases, parasites like pubic lice, which usually live in the groin area, can also show up in beards. However, other studies have challenged the idea that beards increase infection risk. One investigation concluded there was no significant difference in bacteria colonization between bearded and clean-shaven healthcare workers. But Dr Freestone said: 'Neglected beards can foster irritation, inflammation and infection. 'The skin beneath a beard – rich in blood vessels, nerve endings and immune cells – is highly sensitive to microbial and environmental stressors. 'When sebum, dead skin, food debris and pollutants accumulate, they can irritate the skin and provide fuel for fungal and bacterial growth.' Bearded men should wash their beard and face every day, experts say, to help remove dirt, oils, allergens and dead skin. Other tips include moisturizing to prevent dryness, using a beard comb to remove debris, and trimming to control loose hairs. 'With daily hygiene and proper grooming, beards pose little risk and may even be healthier than we once thought,' Dr Freestone concluded.

You're cooking your steak wrong! Scientists reveal the Einstein-inspired formula for a perfect fillet
With Father's Day approaching, some Brits may be planning on rustling up a nice dinner to treat their Dad. Now, scientists have revealed the formula for cooking the perfect steak – and it's all down to how heat moves through meat. The equation, inspired by Albert Einstein, features one very important factor – the thickness of the meat. And since the total cooking time can vary from three to 14 minutes, it's one equation that could turn out very useful in the kitchen. It has been devised by Professor Rob Appleby, a physicist from the University of Manchester and a trained chef. He has utilised a formula first worked out by Einstein - L² = 4Dt - originally used to describe the motion of particles. In the formula L represents the thickness of the steak, T is the time for the steak to cook and D is the diffusion coefficient, which is the speed at which heat moves through the fillet. Professor Appleby has used the equation to create a simplified timing chart to help home chefs master steak – so, will you put it to the test? 'Steak science is surprisingly precise,' Professor Appleby said. 'It's not the weight of the steak that matters, but its thickness. 'Heat takes longer to travel through thicker meat, and Einstein's formula helps us understand exactly how long it takes.' He explained that the time it takes to cook a steak increases with the square of its thickness. That means doubling the thickness of a steak doesn't just double the cooking time - it can quadruple it. This insight busts one of the biggest BBQ myths – that a steak twice as big takes twice as long to cook. By using the formula and a simple temperature probe, home cooks can avoid overcooking, undercooking or the dreaded burst-outside, raw-inside steak disasters. 'A 2cm-thick steak might take just four minutes in total, while a 4cm steak could take over 12 minutes,' Professor Appleby said. The timing is perfect for Father's Day weekend, when some people might be firing up their BBQs. 'People are always nervous about steak, especially on a BBQ, but this takes the guesswork out,' Josh Novell, from Polhill BBQs, said. 'You don't need to be a physicist; just have the right tools and the right method. 'When you're cooking over flames or coals, heat zones vary and it's easy to burn the outside before the centre's ready. 'But by understanding how heat travels through the steak, you avoid solely relying on instinct.' Steak cuts explained RUMP: The rump steak is a cut of beef taken from the hindquarter of the animal, specifically the upper part of the leg. This area is a hard-working muscle, which means that the meat is leaner than other cuts, but also incredibly flavourful. RIBEYE: Ribeye is a classic steak cut, known for its exceptional flavour and marbling. Cut from the rib section of the cow, it is one of the most tender and juicy cuts available. The ribeye is characterized by its distinct eye of marbling, which ensures a rich and juicy flavour when cooked. FILET MIGNON: Filet Mignon is known as the king of steaks, thanks to its extreme tenderness and delicate, buttery flavour. This steak comes from the tenderloin, which is located just below the spine of the cow. Because this muscle isn't used as much during the cow's lifetime, it is one of the most tender cuts available. FILLET: The fillet steak, or tenderloin steak, is a cut of beef that comes from the tenderloin – a long, slender muscle located beneath the ribs and along the spine of the cow. This muscle does very little work, resulting in a cut that is incredibly tender and delicate. Due to its premium quality and limited availability (only about 4-6 pounds of tenderloin per cow), fillet steaks are often considered a luxury item and can command a higher price at your butcher than other cuts. SIRLOIN: Sirloin is a versatile steak cut, characterized by its lean, but flavourful meat. It comes from the rear of the cow, just before the rump. Because this muscle is used frequently during the cow's lifetime, sirloin can be less tender than other cuts but still has a unique and robust taste. T-BONE: The T-bone steak is a combination of two steaks: the tenderloin and the strip steak. It is characterized by a T-shaped bone in the centre, which separates the two cuts of meat. T-bone is known for its rich beefy flavour and tenderloin's buttery, tender texture. PORTERHOUSE: Porterhouse is similar to T-bone in that it consists of two steaks separated by a Tshaped bone. However, it has a larger portion of the tenderloin, making it the ideal steak cut for those who want the best of both worlds. It's a big steak, perfect for sharing or perfect for a large appetite. NEW YORK STRIP: The New York Strip is a popular steak cut known for its juicy and flavourful meat. This steak comes from the beef loin and is characterized by its leaner, yet still tender, texture. Because of its consistency, it can take on a range of marinades and seasonings, making it a versatile steak. FLANK: Flank steak is a lean cut of meat that comes from the abdominal muscle of the cow. While not as tender as other cuts, it is known for its rich flavour and versatility in cooking. Flank steak is ideal for grilling or pan-frying, and it makes an excellent addition to salads or tacos.

Eating 75p fruit daily linked to better sleep and lower risk of silent killer, say scientists
SCIENCE now confirms sleep is as important as nutrition and exercise when it comes to overall health. And one specific fruit, when eaten daily, could be key to getting those all important forty winks. A new study suggests eating one avocado a day can positively impact sleep. Participants who consumed one avocado daily for six months reported better sleep compared to those who ate fewer than two avocados per month. The researchers also looked at the effect this had on cardiovascular health, as previous studies have shown insufficient or disrupted sleep can increase the risk of 'silent killer' condition heart disease. In the study, 969 American adults took part, and all had elevated waist circumstance - a cardiovascular risk factor. Participants were picked at random to either consume one avocado a day or less than two avocados per month, while continuing their usual diet for six months. Their cardiovascular health was then assessed using the AHA's Life Essential 8 tool, which identifies diet quality, physical activity, nicotine exposure, sleep, body weight, blood pressure, blood lipids, and blood glucose as leading behaviours and factors that when improved can lead to better health outcomes. Daily avocado intake was linked to improved diet quality, blood lipids, and sleep health. But no other significant effects were found for the other Life's Essential 8 components. The study wasn't originally designed to examine sleep as a primary outcome, but bridges the gap for further research into how the nutrients in avocados may support aspects of cardiovascular health. Avocados contain a number of nutrients that play a role in sleep. Five best stretches to improve sleep They're a good source of tryptophan, an essential amino acid that plays a role in serotonin production, which can impact mood and sleep. They also contain folate, which is involved in melatonin production, and magnesium, which aids in muscle relaxation, further supporting sleep regulation. And their magnesium content can support muscle relaxation and stabilise blood sugar levels. Additionally, the combination of fibre and monounsaturated fats in avocados contributes to their beneficial impact on cardiovascular health. Fibre can help reduce cholesterol levels and improve blood sugar control, both important factors in heart health. And monounsaturated fats, a type of healthy fat, can help lower LDL ("bad") cholesterol levels and raise HDL ("good") cholesterol levels. 2 If you're struggling to sleep or think you have a sleep disorder like insomnia, the NHS recommends trying the following tips: go to bed and wake up at the same time every day relax at least one hour before bed, for example, take a bath or read a book make sure your bedroom is dark and quiet – use curtains, blinds, an eye mask or ear plugs if needed exercise regularly during the day make sure your mattress, pillows and covers are comfortable You should avoid: smoking or drinking alcohol, tea or coffee at least six hours before going to bed eating a big meal late at night exercising at least four hours before bed watching television or use devices, like smartphones, right before going to bed, because the blue light makes you more awake napping during the day driving when you feel sleepy sleeping in after a bad night's sleep and stick to your regular sleeping hours instead If you've had trouble sleeping for months, speak to your GP. Avocados can be bought for as little as 75p from Sainsbury's. Other foods that can help with sleep Milk A classic sleep aid, warm milk contains tryptophan, which is converted into serotonin and then melatonin, both of which promote sleep. Turkey Another good source of tryptophan, turkey can be included in a balanced pre-bed snack. Eggs Eggs are a good source of protein and tryptophan, which can help regulate sleep-wake cycles. Almonds A good source of magnesium, which is important for muscle relaxation and sleep quality. Spinach Leafy greens like spinach are also rich in magnesium. Avocados A healthy source of magnesium and healthy fats. Tart cherries Tart cherries naturally contain melatonin, a hormone that regulates sleep-wake cycles. Walnuts Walnuts are another good source of melatonin and contain healthy fats. Kiwi Kiwis contain melatonin and serotonin, which can help promote sleep. Oats Oatmeal can help keep blood sugar levels stable and promote sleep.
