Genetics alone can mean a 21% greater risk of early death, research finds, but people can improve their chancesA healthy lifestyle may offset the impact of genetics by more than 60% and add another five years to your life, according to the first study of its kind.It is well established that some people are genetically predisposed to a shorter lifespan. It is also well known that lifestyle factors, specifically smoking, alcohol consumption, diet and physical activity, can have an impact on longevity. Continue reading...
In a first, researchers were able to compare records of people who drank polluted water in Veneto, Italy, with neighbors who did notFor the first time, researchers have formally shown that exposure to toxic PFAS increases the likelihood of death by cardiovascular disease, adding a new level of concern to the controversial chemicals' wide use.The findings are especially significant because proving an association with death by chemical exposure is difficult, but researchers were able to establish it by reviewing death records from northern Italy's Veneto region, where many residents for decades drank water highly contaminated with PFAS, also called forever chemicals".

Ursa Major covers a little more than 3% of the entire night sky, making it the third largest constellation by areaThe seven brightest stars in Ursa Major, the Great Bear, form the shape known as the Plough, or the Big Dipper, or by a number of other names in different cultures.The association with a bear dates to antiquity, when it was listed in Ptolemy's original 48 constellations from the second century AD. Now incorporated into the International Astronomical Union's list of 88 modern constellations, it covers a little more than 3% of the entire night sky, making it the third largest constellation by area.

We often have as much in common with strangers as our relatives, according to studies - so why do we still love to say our children are like us?How alike are parents and kids? Quite, right? Surely we all play that game. I, for example, am competitive like my dad (but without a shred of his energy); my sister got my mother's compassion and I got her lust for crispy potato products and staying in bed. My husband and his mum, meanwhile, share a lively debating style (I'm choosing my words carefully); it's why their conversations get so ... animated.It's an assumption that transcends geography: there are the apple doesn't fall far from the tree" equivalents worldwide - mostly tree-related, although I like the Portuguese a fish's child knows how to swim".

Often misused by politicians, nostalgia is a positive emotion that could do with a makeoverI have always been prone to homesickness. As a child, I didn't really enjoy holidays, I dreaded going away on school trips and I hated sleepovers. At the beginning of 2021, when I first started thinking about the history of nostalgia, and in the midst of the pandemic, I moved across the Atlantic from London to Montreal, Canada, for work. Far from home and away from my family and friends, I felt a kind of grief whenever I thought about the life I'd left behind. There was so much to love about my new life but I felt anxious, worrying constantly about the safety and wellbeing of my parents, siblings and friends. What if, due to the time difference, I missed an urgent call or woke up to terrible news? These fears were, of course, unfounded, and they were also ridiculous, childish even. Grownups - married 30-year-olds with mortgages and full-time jobs - shouldn't miss their mums.I also tend to be homesick in a weirder, more abstract way - homesick for somewhere I've never been. It's a feeling otherwise known as nostalgia. Melding fairytales with Horrible Histories, as a child I spent hours imagining myself transported back in time to invented and romanticised versions of the past. I was an avid reader of Enid Blyton's novels and, despite my homesick inclinations, begged my parents to divert me from my 1990s London primary school to a boarding school in 1950s Cornwall. My pleas went unanswered, so I went to my uniform-free state school every day in pleated skirts and white blouses, desperate to return to a world I'd never inhabited. Continue reading...
We can get into the habit of thinking about our sibling with judgment and criticismThe question Since our mother's death, my brother and I have had no contact. He lives more than 100 miles away. Our relationship has been very difficult for over 40 years. When we both had young children, things were better for a time. When our dad died, Mum's health deteriorated and she moved in with me and died 12 years later. During this time, my relationship with my brother was at its worst. Before retirement, we both worked in mental health, but neither of us understand why our family relationship has been so fractured.There is a family history: our grandfather did not get on with his sister, he and his wife kept secrets, and our dad fell out with his twin! Our childhood was difficult as our father had mental health issues. Continue reading...
Why has so little been done to make indoor spaces safer, to stop the spread of airborne viruses?Robin McKie's article rings alarm bells for global health and our failure to control airborne pathogens (What virus will cause the next pandemic? It's flu, say scientists").We are rightly looking with concern at the spread of H5N1 and the risk it poses to humans, but we have still not applied the hard-won lessons learned from Covid19. While all agencies and experts now (belatedly) admit to Covid's airbornespread, very little has been done to make indoor spaces safer forus all, and the clinically vulnerable in particular, for whom shops, workplaces, restaurants, and even clinical settings have become high-risk areas.

Austrian astronomer Lisa Kaltenegger has spent her life hunting for signs of life in the universe. Here she talks about aliens, space exploration and why studying cosmology is like eating pizzaStaring into the abyss... Am I really reaching anyone out there?" Lisa Kaltenegger is laughing about the unsatisfactory experience of teaching astrophysics over Zoom during Covid lockdowns, but she could be talking about her vocation: trying to discover if there's life beyond our solar system.Kaltenegger founded the Carl Sagan Institute in 2015 to investigate just that. A burst of sunny energy and infectious enthusiasm on a grey day, she's speaking to me from the legendary extraterrestrial life researcher's old office, now hers, overlooking the leafy Cornell campus in upstate New York. The institute brings together researchers across a range of disciplines to work out what signs of life on other planets might look like from here, so that we recognise them if (or when) we find them.

Scientific studies cannot agree on the relative importance of genes and environment on how we turn out as adultsThe eternal mystery of how much we are shaped by our parents - or how much we shape our children - was stirred again last week with the publication of a study that suggests that we are less like our parents than we had previously thought.Led by Rene Mottus of Edinburgh University's department of psychology, the study looked at more than 1,000 pairs of relatives to establish how likely children are to inherit what psychologists call the big five" or Ocean" personality traits: openness, conscientiousness, extraversion, agreeableness and neuroticism.

Scientists hope studies into Boyajian's star could lead to enhanced techniques for identifying distant planetary civilisationsIt is our galaxy's strangest star, a flickering globe of light whose sporadic and unpredictable output has baffled astronomers for years. But now the study of Boyajian's star is being promoted as a research model that could help in one of the most intriguing of all scientific quests: finding intelligent life on other worlds.This is the argument that Oxford University astrophysicist Prof Chris Lintott will make at a public lecture - Is it Aliens? The Most Unusual Star in the Galaxy - at a Gresham College lecture in Conway Hall, central London on Monday. His prime target will be Boyajian's star, sometimes nicknamed Tabby's star after scientist Tabetha Boyajian, in the constellation Cygnus whose odd dimming and brightening has been the subject of intense study by space probes and observatories in recent years.

Staying close to friends isn't always easy. From calling out flakiness to singing together in a choir, experts share their advice on how to keep the spark aliveThere is no getting around it, you have to make time to be a good friend. According to Robin Dunbar, professor of evolutionary psychology at the University of Oxford and author of Friends: Understanding the Power of our Most Important Relationships, we need to spend the equivalent of nine minutes a day to maintain a healthy relationship with our closest network of friends, which he admits is barely time to raise your coffee cup to each other", so one meet-up a week is more realistic. If you fail to do that, the friendship starts to decay", says Dunbar. Continue reading...

Global warming and international trade offering increasingly hospitable environmentSome are small and jumpy; others are large and intimidating - if you're a humble housefly. Exotic spiders are flourishing in Britain as international trade offers ample opportunities for spider travel and global heating provides an increasingly hospitable climate.A jumping spider new to science has been identified living on the Penryn campus in Cornwall, home to the University of Exeter and Falmouth University. The nearest known relative of the 3-4mm-long Anasaitis milesae is found in the Caribbean, making it highly likely that this tiny species - alongside 17 other non-native jumping spider species - found its way to Britain from distant climes.

DeBose's brilliant rookie astronaut navigates this moderately tense thriller about US and Russian crew fighting as Earth blazes belowAt first, the crew on board the International Space Station (ISS) mistake the tiny dot of fire on Earth for a volcano. But look: there's another, and another. In fact, these astronauts have got a bird's eye view of a nuclear tit-for-tat between the Russian and American governments that by the end of the movie turns the planet into a great glowing ball of fire. But for the six-person crew - three Americans and three Russians - nuclear Armageddon is only the start of their problems.A lowish-budget, slightly muted survival thriller - moderately tense, with too few ideas to qualify as actively cerebral - what the movie does have is a brilliant performance by West Side Story's Ariana DeBose as biologist and rookie astronaut Kira. Like all the characters here, she's a bit too thinly sketched, but DeBose brings real warmth and likability to the part, making Kira easy to root for. And there are some interesting moments as she adjusts to zero gravity. Continue reading...

Research that aims to explain why some people experience intense visual imagery could lead to a better understanding of creativity and some mental disordersWilliam Blake's imagination is thought to have burned with such intensity that, when creating his great artworks, he needed little reference to the physical world. While drawing historical or mythical figures, for instance, he would wait until the spirit" appeared in his mind's eye. The visions were apparently so detailed that Blake could sketch as if a real person were sitting before him.Like human models, these imaginary figures could sometimes act temperamentally. According to Blake biographer John Higgs, the artist could become frustrated when the object of his inner gaze casually changed posture or left the scene entirely. I can't go on, it is gone! I must wait till it returns," Blake would declaim. Continue reading...
