Plants may be able to help investigators find dead bodies. Botanists believe the sudden flush of nutrients into the soil from decomposition may have an impact on nearby foliage. If scientists can understand those changes – for instance, the effect they have on leaf colour – they may be able to identify where remains are buried simply by studying foliage features in aerial images.
“If we’re able to use the plants as sensors, at least first as indicators or crude indicators, we can identify whether a missing body may … More

Most psychology studies involve people living in Western, Educated, Industrialised, Rich and Democratic societies. But the peculiarities of WEIRD thinking are far from universal

HOW does the culture we live in influence our psychology, motivation and decision making? Joe Henrich was a cultural anthropologist working in the Amazon when he first tried to find out. He pioneered the use of experimental cooperation games like the prisoner’s dilemma and the ultimatum game outside the lab. Later, he realised that his findings have big implications for psychological research, which tends to focus on students from Western backgrounds. In 2010, he introduced the “WEIRD” concept to describe the unusual psychology of the subjects in the vast majority of these studies. Now professor of human evolutionary biology at Harvard University, he tells New Scientist about the origins of WEIRDness, its impact on history and its role in the modern world.
Dan Jones: When did you realise that you, your colleagues and most of the people you teach are WEIRD?
Joe Henrich: The WEIRD label emerged from a series of lunches I started having around 2006 with two cultural psychologists, Steven Heine and Ara Norenzayan. We had noticed that in the behavioural sciences and psychology in particular, about 96 per cent of study participants were from Western, Educated, Industrialised, Rich and Democratic societies – and that they were often psychological outliers in comparison with other populations. WEIRD people tend to show greater trust in strangers and fairness towards anonymous others; think more analytically rather than holistically; make more use of intentions in moral judgements; are more concerned with personality, the self and the cultivation of personal attributes; they are more individualistic and less loyal to their group; and they are more likely to judge the behaviour of … More

So Hot Right Now podcast looks to David Attenborough and Ellie Goulding in bid to make climate crisis more real for millions and push it up the media agenda

THE way that we communicate the climate crisis needs a rethink, from the language used in daily conversations to the frequency it makes front page headlines.
The So Hot Right Now podcast goes to the heart of the issue. Far from detailing climate science, species extinctions or innovative technical fixes, the show questions the status quo and shares refreshing insight from experts, campaigners and front-line presenters.
“We tend to focus on gaps in our climate science knowledge and there’s so much to learn, but what people are less alert to is this massive gap in coverage and that’s hampering our chances of mainstreaming these topics. We need more airtime, more screen time for climate and nature,” says co-host, journalist Lucy Siegle. “We’re pushing the agenda, uncovering the barriers and exploring why the gatekeepers are not opening the gates, but also speaking to some of our heroes and asking them ‘what should we do?’.”
Siegle and wildlife film-maker Tom Mustill interview A-list guests such as Mary Robinson, former president of Ireland, UN climate negotiator Christiana Figueres and singer Ellie Goulding, who believes activism jeopardises her job. “I lose followers [on social media] every time I post about climate change. I lose at least a thousand followers,” says Goulding during a podcast. She continues to speak up regardless.
In the first episode, David Attenborough says he has no idea why Blue Planet II sparked such an extreme public reaction to plastic pollution when he had been “plugging away” at the issue for years. “Suddenly, there was an unprecedented response, possibly down to the scheduling or the mood of the nation. Audiences are very hard to predict,” he says.

Successful communication hinges on finding new avenues of storytelling that connect us to the natural world. As BBC Springwatch presenter Gillian Burke concludes in a later episode: “I’m really starting to play with the language, storytelling, identity and labels. If we’re looking at the climate crisis through the lens of an Aboriginal person in Australia, how will that story be different? Language for me is a gateway to revealing more about the way we see the world.”
Nuance exists in every word we use, suggests Siegle: “If language is too comfortable, it can minimise threat and the need for action, it can sometimes be downright dismissive or it can be too technical, forgetting that we respond to emotion, or it can be too emotional and not precise enough.” Or, as Mustill adds, “it can be really boring. Part of the aim of communication is surely to entertain. No one wants to be a climate bore.”
With a curious yet informal tone, some episodes last more than an hour and might work better as shorter, more finely tuned pieces. But there are no set rules and So Hot Right Now embraces the freedom to be experimental.
At times, the hosts seem starstruck (David Attenborough is thanked repeatedly for all he has done to inspire generations) but, generally, Siegle and Mustill enthusiastically arm listeners with a toolkit of useful strategies to articulate big ideas about climate and trigger more discussions.
Whether you are addressing world leaders about the environment, connecting with social media followers about the issue or arguing with relatives about it, So Hot Right Now is well worth a listen.

Star Trek, which began in 1966, is experiencing an extraordinary renaissance in the year 2020. Is this a golden age for the show, asks Emily Wilson

THE very first episode of Star Trek, entitled The Man Trap, aired on 8 September 1966. Right from the start, all the key ingredients of Star Trek were there: an alien planet with air that was perfectly OK to breathe and strange lumps of rock on its surface that are good to hide behind in a firefight; very closely fitted colour-blocked uniforms; a key gang of ship’s officers, including the captain, the Vulcan and the ship’s doctor; and, of course, a really big spaceship, with that lift leading down from the bridge to the other decks.
There are a few things in that first show that have since disappeared, such as female crew members wearing skirts so short they barely covered their bottoms. But all the elements of Star Trek‘s success were present in that story about an alien that killed people because it was badly short of salt.
What no one working on the show back then could possibly have imagined is that 54 years later, and in a very different world, Star Trek would not only still be in production, but that it would be thriving and, indeed, multiplying. Whether or not this is a new golden age of Star Trek is for each fan to decide for themselves, but it is certainly an exciting period of renaissance.
“Star Trek: Lower Decks, I’m informed by a US colleague, is ‘being watched by all the cool people’”
My personal favourite of the crop of new series is Star Trek: Discovery, which kicked off in 2017. Discovery was the first new Star Trek TV series since Star Trek: Enterprise ended in 2005. It centres around science specialist Michael Burnham, played brilliantly by Sonequa Martin-Green. Burnham is largely sombre and angst-ridden, and yet you end up not only rooting for her but caring about her.

The rest of the show is rammed full of great ideas as well as other strong characters, including the fabulous Michelle Yeoh as Philippa Georgiou in a role that warps in very interesting ways as the show goes on. The second season came out late last year, and the third is due to be released this October, and if that happens, hurray!
Elsewhere in this renaissance is Star Trek: Picard, which was released in January, with Patrick Stewart reprising the role he played in Star Trek: The Next Generation (a hugely popular iteration of the franchise that ended in 1994). Picard is a slower show than Discovery and, in my view, is less successful as a piece of storytelling, but it isn’t without its pleasures. A second and third season are on their way.
Then there is Star Trek: Lower Decks, an adult animated series that is only available to watch in North America right now. I am informed by a US colleague that it is “being watched by all the cool people”.
These three are only one part of the new wave of Star Trek, though. So much more is coming, including, apparently, a live-action show based around Yeoh’s rumbustious character in Discovery that is tentatively titled Section 31.
All these new shows harness the very best modern effects and all the narrative tricks learned from the masters of binge-watchable TV, and the Star Trek franchise has definitely come a long way since The Man Trap.
But the latest shows remain, indubitably, Star Trek. At their heart, there is still a bunch of people in tight uniforms, on a big spaceship, visiting alien worlds and taking with them Star Trek‘s particular brand of tolerance and hope. What’s not to like about that?

Stargate SG-1

The Stargate franchise has a central simplicity to it that is quite Star Trek: humans going forth to strange new worlds to find and help others. It was kicked off by the 1994 film Stargate and now has a number of massive spin-off shows. For me, the 10 seasons of SG-1 are the main event. Aliens, jokes, great characters, pyramid ships, intergalactic narrative arcs – the show has everything.

In Guynecology, Rene Almeling argues that moving away from gendered ideas about reproduction could improve our health and transform our societies

MALE bodies have long been seen as the norm when it comes to science. It is men and male animals that have been studied to understand what good and poor health looks like, as well as how to treat disease – except, that is, when it comes to reproduction.
Historically, baby-making has been viewed as the defining function of women’s bodies, so much so that other aspects of their health have been neglected. For example, heart attacks are less readily identified in women, who are 59 per cent more likely to be misdiagnosed despite the fact that cardiovascular disease is the leading cause of death in women.
Meanwhile, research into men’s reproductive health has lagged behind. Attempts to understand their contribution to fertility, miscarriage risk and long-term risk of a child developing some mental health conditions, for example, have only recently gained ground.
In Guynecology, Rene Almeling, a sociologist at Yale University, explores how attempts to kick-start the study of men’s reproductive health failed. Even now, as the role of health in sperm function and in the well-being of future children becomes clear, information is still scarce and gendered notions about a woman’s role in making babies persist, she writes.
Take the age-old notion of the coming together of “aggressive” sperm and “passive” eggs. The idea that conception is largely the role of the sperm cell is still a very popular one, but it isn’t true. We now know eggs release chemicals to sperm when they are ready to be fertilised, and recent research suggests that these might help select some sperm over others.

When it comes to men’s role in reproduction, the focus has been on sex rather than fatherhood, centring on sexually transmitted infections and conditions like erectile dysfunction. While women’s reproductive health has long been seen as key to their well-being, “men’s genitals were never seen as core to their health and psychology as women’s genitals were [to women]”, says Almeling.
“Shifts in how we understand gender might transform how reproduction and fertility are studied”
Her book tackles an important subject, but there are some dry sections. Best to skip to her coverage of recent research. One of the most important findings is how lifestyle choices significantly influence the health of sperm, and consequently of children. Men, too, have a “biological clock”, and their age, diet and smoking habits have been linked to issues such as miscarriage and risks of low birth weight.
These factors seem to have lasting “epigenetic” effects, conferring changes to the genome that mean new genetic risks of disease can be passed on to children. The field is still young, but there does appear to be a link between certain “paternal effects” and the risk of schizophrenia, for instance.
Yet while dietary advice abounds for women trying to conceive, men may be less aware of the dos and don’ts, warns Almeling. She points out that there is little to no information on paternal effects offered to these would-be parents by US federal bodies and health agencies.
Almeling rounds off her book with recommendations for scientists, healthcare providers and policy-makers. She thinks part of the problem is seeing gender as binary, with men and women as opposites, and that shifts in our understanding of gender might transform how reproduction and fertility are studied and treated.
A greater understanding of men’s reproductive health could also “reshape gender politics in surprising ways” and change gendered expectations of women about reproduction, she writes. Almeling suggests such changes may help reduce the gender pay gap and inequalities caused by the assumption that women (but not men) with children are less committed to their jobs.
Nice theory, but considering how long it has taken for women to get this far, I won’t hold my breath.
