Evolution of bat wings and calls through ‘foraging syndromes’ allows diversity to flourish

By Mischa Dijkstra, Frontiers science writer Egyptian slit-faced bats, Nycteris thebaica In a new study, scientists show that the wing shape and the echolocation frequency of bats are tightly linked across species. This pattern could only be identified because of the large dataset in the present study, which allowed the authors to look beyond the effect of bat family on these traits. The results mean that wing shape and echolocation frequency have jointly evolved in response to foraging ecology, yielding an optimal combination of traits or ‘foraging syndrome’ in each habitat. Bats are an evolutionary success story. With approximately 1,400 species living today, they thrive in every environment except the polar regions. They come in a remarkable range of sizes, from the golden-crowned flying fox with a mass of 1.2 kg and a wingspan of 171 cm, to Kitti’s hog-nosed ‘bumblebee’ bat with a mass of 2 g and a wingspan of 33 cm. The frequencies that bats emit during echolocation are also highly variable, ranging from 11 kHz to 212 kHz. But what has driven the evolution of this extraordinary diversity? “Here we show with that among bat species, there is a close correspondence between wing shape and the […]

Flocking to fire: wildfires don’t deter Americans from moving to at-risk regions

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Scientists investigated whether environmental hazards put people off moving to regions at risk and found that heatwaves and hurricanes deter newcomers, but wildfires don’t. The climate crisis has caused humans to move both within their countries of origin and across borders. Although climate migration is often treated as a phenomenon of the ‘global south’, a team of scientists led by Mahalia Clark at the University of Vermont (UVM) turned the spotlight on the US. The US has experienced numerous destructive weather events recently, which have killed and injured many people and done billions of dollars of damage. But the team found that despite the death toll, more people are moving to areas in the United States that are at serious risk of wildfires. “Our original motivation was the increasing number of headlines each year about record breaking heat waves, hurricanes, and wildfires,” said Clark, a researcher at UVM’s Gund Institute for Environment. “I had been studying natural amenities — features of the climate and environment that are attractive to movers — but I began to wonder if the threat of these hazards might have a deterring effect on migration.” Read original article […]

Could new cancer drugs come from potatoes and tomatoes?

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Polish scientists revealed the potential for new cancer drugs to be formulated from bioactive compounds found in plants from the genus Solanum, like potatoes and aubergines. Everyone knows someone who has had cancer. In 2020, around 19m new cases — and around 10m deaths — were registered worldwide. Treatments are improving all the time but can damage healthy cells or have severe side-effects which are hard on patients; in the search for new, more targeted cancer drugs, traditional medicine offers many possible candidates. A team of Polish scientists led by Magdalena Winkiel at Adam Mickiewicz University, publishing today in Frontiers in Pharmacology, reviewed the bioactive compounds called glycolalkaloids that are found in many vegetables that are household names, like potatoes and tomatoes, to demonstrate their potential to treat cancer. “Scientists around the world are still searching for the drugs which will be lethal to cancer cells but at the same time safe for healthy cells,” said Winkiel. “It is not easy despite the advances in medicine and powerful development of modern treatment techniques. That is why it might be worth going back to medicinal plants that were used years ago with success […]

Scientists find inorganic food additives might make babies more vulnerable to allergies

By Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Inorganic nanoparticles used to help process food may be crossing the placental barrier and getting into breastmilk, potentially damaging intestinal regulation and compromising babies’ oral tolerance, predisposing them to food allergies. Nanotechnologies have revolutionized food technology with changes to food production, manufacture, and processing that are intended to make our food safer and healthier. Phytosanitary products, processing aids, food additives, and surfaces that touch food in storage can all transfer nanoparticles that might be consumed by humans. In a review published in Frontiers in Allergy today, Mohammad Issa, at the Université Paris-Saclay, and colleagues pointed out that such a significant change to food production could have unforeseen health consequences. The team presented evidence that suggested that nanoparticles not only cross the placenta to reach developing fetuses but leave them at greater risk of potentially life-threatening food allergies. “Due to the immunotoxic and biocidal properties of nanoparticles, exposure may disrupt the host-intestinal microbiota’s beneficial exchanges and may interfere with intestinal barrier and gut-associated immune system development in fetus and neonate,” said Dr Karine Adel-Patient, corresponding author of the study. “This may be linked to the epidemic of immune-related disorders in children, such as […]

‘The Maya had, and continue to have, a creative impact on forest composition’ – Dr Anabel Ford

El Pilar, an ancient Maya site in Belize In our Frontier Scientists series, we talk to Dr Anabel Ford, a leading researcher on the ancient Maya, about her career and research interests. Ford recently published a study in Frontiers in Ecology and Evolution in which she stressed the importance of the traditional milpa land use system for the Maya civilization, not only in the Classical Period, but also today. Dr Anabel Ford is a US archeologist who specializes in the ancient Maya of Central America. In 1983, she led the team that encountered the ancient Maya city of El Pilar in Belize. Ford is a faculty member of the Institute of Social Behavioral and Economic Research at the University of California Santa Barbara and the director of the MesoAmerican Research Center at the same university. She is an expert on the still-flourishing forest gardens of the Maya region, built up over several millennia of traditional land use by the Maya people. Recently she published the study, “Scrutinizing the paleoecological record of the Maya forest” in Frontiers in Ecology and Evolution. In the paper, she focuses on the traditional milpa-forest garden cycle, where maize, beans, squashes, tomatoes, and many others are […]

How to write a manuscript: Expert advice on getting published

By: John R. Porter, Helen Kimbell, Aida Finn, Catarina Alves, and Bhagirath Chauhan There’s a saying in science – ‘publish or perish’, meaning your ability to pursue a scientific career is highly dependent on the number and quality of papers you produce. In short, publications are your scientific currency. Writing papers helps your results to be confirmed or challenged by other scientists, allowing your findings to help move your field of interest forward. So how do you write a manuscript? First, prepare your paper. The most important thing to remember is the order in which other scientists will read your paper is not the same as the order in which you should prepare it. A good rule at the start of your career is to focus on writing about what you know before drawing up the introduction and summary. Materials and methods come first because writing about these should come naturally – you know this better than anyone else. Following this will be the results section. This means analyzing and deciding which data you wish to present and then formulating it into tables or graphs. You don’t have to present all the data you’ve collected in your paper. In fact, […]

Biomarker in urine could be the first to reveal early-stage Alzheimer’s disease

By Conn Hastings, science writer Image: BlurryMe/Shutterstock.com Alzheimer’s disease can remain undetected until it is too late to treat. Large-scale screening programs could help to detect early-stage disease, but current diagnostic methods are too cumbersome and expensive. A new study published to Frontiers is the first to identify formic acid as a sensitive urinary biomarker that can reveal early-stage Alzheimer’s disease, potentially paving the way for inexpensive and convenient disease screening.   Could a simple urine test reveal if someone has early-stage Alzheimer’s disease and could this pave the way for large-scale screening programs? A new study in Frontiers in Aging Neuroscience certainly suggests so. The researchers tested a large group of patients with Alzheimer’s disease of different levels of severity and healthy controls with normal cognition to identify differences in urinary biomarkers. They found that urinary formic acid is a sensitive marker of subjective cognitive decline that may indicate the very early stages of Alzheimer’s disease. Current methods to diagnose Alzheimer’s are expensive, inconvenient, and unsuitable for routine screening. This means that most patients only receive a diagnosis when it is too late for effective treatment. However, a non-invasive, inexpensive, and convenient urine test for formic acid could be […]

How you help a child go to sleep is related to their behavioral development, finds new study

By Suzanna Burgelman, Frontiers science writer Image: yamasan0708/Shutterstock.com A group of international researchers examined parental methods to help toddlers sleep across 14 cultures and found that these methods are related to the development of a child’s temperament. The researchers suggested focusing on better sleep-related parenting practices to support positive behavioral development across cultures. The importance of good sleep during childhood development has been extensively researched. Bad sleep quality and behaviors are detrimental to neurobehavioral functioning, emotional reactivity and regulation, and can pose a risk for future psychopathology. “Parental sleeping techniques are correlated with children’s sleep quality, and the importance of cultural context in child development has been long recognized,” said corresponding author Ms Christie Pham, of Washington State University. “We wanted to examine whether cross-cultural differences in parental sleep-supporting strategies account for differences in toddler temperament.” In a study published in Frontiers in Psychology, Pham and her colleagues studied the effect of different parental sleep-supporting techniques on child temperament across 14 cultures. They hypothesized that passive ways of helping a child fall asleep (eg, cuddling, singing, and reading), but not active methods (eg, walking, car rides, and playing), would be positively related to a child’s temperament. ► Read original article► Download original […]

World’s heaviest flying bird may be self-medicating on plants used in traditional medicine

By Mischa Dijkstra, Frontiers science writer Great bustard male displaying on lek. Image credit: Carlos Palacín Researchers show that great bustards in Spain prefer to eat two plant species with compounds active in vitro against protozoa, nematodes, and fungi: corn poppies and purple viper’s bugloss. Males, who spend much time and energy on sexual displays during the mating season, have a stronger preference for these plants than females, and more so during the mating season than at other times of the year. The authors thus consider great bustards as prime candidates for non-human animals that self-medicate, but stress that more research is needed to definitively prove this. If you see a great bustard (Otis tarda) in the wild, you’re unlikely to forget it. Massive, colorful, and impossible to mistake, they are the heaviest birds living today capable of flight, with the greatest size difference between the sexes. They are also ‘lek breeders’, where males gather at chosen sites to put on an audiovisual show for the visiting females, who choose a mate based on his appearance and the quality of his showbirdship. But now, a study in Frontiers in Ecology and Evolution suggests that great bustards have another claim to […]

Vast phytoplankton blooms may be lurking beneath Antarctic ice

by Angharad Brewer Gillham, Frontiers science writer Image: Shutterstock.com Researchers using NASA’s Earth observing system find that Antarctic sea ice allows enough light in to let hidden phytoplankton bloom in the Southern Ocean. Until now, we thought the packed sea ice of the Southern Ocean blocked all light from reaching the sea beneath, preventing phytoplankton — tiny algae which are the base of aquatic food webs — from growing there. The less light available, the less the phytoplankton can photosynthesize and therefore the less phytoplankton there will be, heavily restricting life beneath the ice. But research inspired by increasing under-ice blooms of phytoplankton in the Arctic has shown that Antarctic waters also have unexpected denizens, indicating that there is underestimated ecological variability under the ice. Blooms are often spotted as soon as the sea ice begins its seasonal retreat, supported by plenty of light and freshwater with high iron content. Yet a team led by Dr Christopher Horvat of Brown University and the University of Auckland suspected that there would already be potential phytoplankton blooms in waiting. Writing in Frontiers in Marine Science, they described using sampling from independent BGC-Argo floats and climate model output to estimate light availability beneath […]

Smart ‘Joey’ bots could soon swarm underground to clean and inspect our pipes

By Mischa Dijkstra, Frontiers science writer Joey’s design. Image credit: TL Nguyen, A Blight, A Pickering, A Barber, GH Jackson-Mills, JH Boyle, R Richardson, M Dogar, N Cohen Researchers from the University of Leeds have developed the first mini-robot, called Joey, that can find its own way independently through networks of narrow pipes underground, to inspect any damage or leaks. Joeys are cheap to produce, smart, small, and light, and can move through pipes inclined at a slope or over slippery or muddy sediment at the bottom of the pipes. Future versions of Joey will operate in swarms, with their mobile base on a larger ‘mother’ robot Kanga, which will be equipped with arms and tools for repairs to the pipes. Beneath our streets lies a maze of pipes, conduits for water, sewage, and gas. Regular inspection of these pipes for leaks, or repair, normally requires these to be dug up. The latter is not only onerous and expensive – with an estimated annual cost of £5.5bn in the UK alone – but causes disruption to traffic as well as nuisance to people living nearby, not to mention damage to the environment. Now imagine a robot that can find its […]
