Most read article of May 2022: Surprising finding shows children grow faster during the school year than summer vacation

By Colm Gorey, Frontiers Science Communications Manager Image: Shutterstock.com Each month, Frontiers shines a spotlight on some of the leading research across a wide range of topics. Here are just some of the highlights that resonated strongly with readers on our news site in the month of May. Children grow faster during school year than during summer holidays It has been long recognized that in western countries, children are more likely to become overweight or obese over the summer. Causes of this include changes in kids’ physical activity and diet over the summer period, including the summer holidays. But in a study in Frontiers in Physiology, scientists from the US show that this ‘obesogenicity’ of summers has another unexpected cause: children grow faster over the school year than over the summer. And because body mass index (BMI) is the ratio of body weight in kilograms and height in meters squared, faster vertical growth during the school leads to increased BMI during summers. “Here we show seasonality in standardized body mass index (BMIz), with children gaining height at a greater rate during the school year compared to the summer,” said Dr Jennette P Moreno, an assistant professor at the USDA/ARS Children’s […]

How bees prove to be skilled mathematicians and 3 other amazing science stories you may have missed

By Colm Gorey, Science Communications Manager Image: Shutterstock.com At Frontiers, we bring some of the world’s best research to a global audience. But with tens of thousands of articles published each year, many often fly under the radar. Here are just four amazing papers you may have missed. What are the odds? Honeybees join humans as the only animals known to be able to tell the difference between odd and even numbers A study published to Frontiers in Ecology and Evolution has created quite a ‘buzz’ among academics after it was found honeybees possess maths skills beyond what was originally thought. Previous studies have shown honeybees can learn to order quantities, perform simple addition and subtraction, match symbols with quantities, and relate size and number concepts. However, this time around, the bees were tasked with solving a parity experiment which involves categorizing two sets of objects as ‘odd’ and ‘even’. The bees were split into two groups: one trained to associate even numbers with sugar water and odd numbers with quinine, a bitter-tasting liquid familiar to gin drinkers. The second group was trained in the reverse with odd numbers linked to sugar water, and even numbers with quinine. Amazingly – […]

Think fast! Clever monkeys plan their food trips to avoid stronger rivals

By Mischa Dijkstra, Frontiers science writer Vervet monkey, Chlorocebus pygerythrus, from K social group in Uganda. Image credit: TJM Arseneau-Robar, KA Anderson, EN Vasey, P Sicotte, JA Teichroeb Researchers show that vervet monkeys take into account complex social contexts to plan their food trips. When higher-ranking competitors are nearby, they rush to secure the best food immediately. But when they have sufficient time, they choose a route that maximizes the total food intake and minimizes travel distance. Vervet monkeys are quick and clever planners of the best route to follow on foraging trips, shows a new study. When dominant group mates are too far away to interfere, vervets tend to choose the shortest route along successive food sites, snacking on each at leisure. But when dominants group mates are nearby, they seem to assess the time before these can approach and displace them at the feeding site. They then choose the route that maximizes their food intake and minimizes travel distance before the competitors’ arrival. These results, published in Frontiers in Ecology and Evolution, mean that vervets have excellent cognitive skills for quickly appraising the social context and planning their route accordingly. These skills allow them to choose foraging strategies […]

Here are just some of the highlights that resonated strongly with readers on our news site in the month of March. Leftovers in prehistoric pots let scientists peek into the kitchen of an ancient civilization How do you reconstruct the cookery of people who lived thousands of years ago? Bones and plant remains can tell us what kind of ingredients were available. But to reconstruct how ingredients were combined and cooked, scientists need to study ancient cooking vessels. “Fatty molecules and microscopic remains from plants such as starch grains and phytoliths – silica structures deposited in many plant tissues – get embedded into vessels and can survive over long periods,” said Dr Akshyeta Suryanarayan, a researcher at the Universitat Pompeu Fabra in Barcelona, Spain, and co-author on a recent study in Frontiers in Ecology and Evolution. In their study, Suryanarayan and co-authors analyzed such ‘leftovers’ in Copper and Bronze Age vessels – including pots, vases, goblets, jars, and platters – from today’s Gujarat, India. “Our study is the first to combine starch grain […]

Leftovers in prehistoric pots let scientists peek into the kitchen of an ancient civilization

By Mischa Dijkstra, Frontiers Science writer Image credit: Marko Kukic / Shutterstock.com Scientists studied animal lipids and microscopical remains of plants in vessels from the Bronze Age Indus Valley Civilization and preceding Copper Age cultures in northern Gujarat, India. By reconstructing the ancient ingredients, their diverse origin, and the ways of preparation, they find evidence for surprising continuity in ‘foodways’ over 1300 years with great cultural change.

Possible treatment for tinnitus? 4 fascinating Frontiers articles you may have missed

By Colm Gorey, Science Communications Manager Image: Shutterstock.com At Frontiers, we bring some of the world’s best research to a global audience. But with tens of thousands of articles published each year, many often fly under the radar. Now, as part of new series each month, Frontiers will highlight just some of those amazing papers you may have missed. 1: New treatment for tinnitus shows promise for further study More than 10% of the world’s population is estimated to live with a condition called tinnitus, where a range of sounds ranging from ringing to buzzing are heard in the ears that never goes away. While ranging in severity, between 0.5% and 3% of people diagnosed with it say their quality of life is impacted, with no known cure. However, researchers in South Korea have published a paper in Frontiers in Neuroscience putting forward hopeful findings that suggest a new treatment method could be possible for subacute and chronic tinnitus. The small study saw 55 patients undergo repeated nerve blocks after stimulation of the trigeminal and facial nerves to modulate the auditory and non-auditory nervous systems via the vestibulocochlear cranial nerve pathways. In more than 87.5% of patients, tinnitus disappeared or […]

In a hot summer, one tortoise can switch from nesting to developing eggs internally Researchers from Australia and South Africa published an article in Frontiers in Ecology and Evolution identifying what may be a novel reproductive strategy in Chersina angulate tortoises that has the potential to enhance the resilience of species to global warming. After observing a captive colony of in Cape Town, South Africa and checking back through historical data, Gerald Kuchling of The University of Western Australia and Margaretha Hofmeyr of the University of Western Cape found that local ambient temperature altered how females deposited their last clutch of eggs. Periods of unusual heat may result in females switching from depositing their eggs in a nest to develop(oviposition), to growing the egg in their body […]

Surprising discovery in Arctic songbird may reveal how it survives challenging migrations

By K.E.D Coan, science writer Snow buntings in winter. Image: Mircea Costina/Shutterstock.com There is still much to learn about how Arctic migratory birds adjust their physiology during different phases of their life. For example, between winter and summer habitats, or during migration. A recent study published to Frontiers shows the first evidence that snow buntings keep their winter traits through migration. These findings may help researchers understand why snow bunting populations are declining, as well as expanding what is known about how buntings, and other species, endure Arctic weather. Snow buntings are equipped for winter even while migrating to their breeding grounds, shows a recent study in Frontiers in Ecology and Evolution. There have been major declines in biodiversity around the world and the snow bunting population has dropped 60% over the last 45 years. The specific cause of this drop is unknown, and this study is among the first to look at the physiological changes that occur during the different life stages of this species (ie between winter and migration). This work provides clues into the future survival of snow buntings, as well as new insights into how species generally endure the harsh cold of the Arctic. ► Read original […]

Bat guts become less healthy through diet of ‘fast food’ from banana plantations

By Tania Fitzgeorge-Balfour, science writer Pallas’s long-tongued bat (Glossophaga soricina) feeding on banana flowers. Image credit: Julian Schneider New research reveals there is a stark difference between the gut bacteria of nectar-feeding bats foraging in conventional monoculture banana plantations and those bats who forage in their natural forest habitat or organic plantations. This is the first study to show an association between habitat alteration, sustainable agriculture and the gut microbiota of wildlife. Nectar-feeding bats foraging in intensively managed banana plantations in Costa Rica have a less diverse set of gut microbes in comparison to bats feeding in their natural forest habitat or organic plantations, reveals new research published today in Frontiers in Ecology and Evolution. This the first study to show an association between habitat alteration, sustainable agriculture and the gut microbiota of wildlife. “Organic and conventional monoculture banana plantations both provide a very reliable food source for some nectar-feeding bat species. However, bats foraging in the intensively managed plantations had a reduced diversity of gut microbes, which could be a sign of gut dysbiosis, an unhealthy imbalance of its microbial symbionts,” explains Priscilla Alpízar, first author of this study, a doctoral student at the Institute of Evolutionary Ecology and […]

Scientists pretend to be Neanderthals to explore how they caught birds in caves for food

By Mischa Dijkstra, Frontiers science writer Image credit: Gorodenkoff / Shutterstock.com From fossil evidence and through scientific role-play, researchers reconstruct that Neanderthals probably used fire and tools to dazzle, corral, and catch choughs, communally roosting birds, inside caves at night. The choughs would not only have contributed welcome calories and micronutrients to the Neanderthals’ diet, but may also have yielded elements for their personal decoration. Neanderthals, our closest relatives, became extinct between 40,000 to 35,000 years ago. Since the discovery of the first Neanderthal fossil 165 years ago, scientists have learned more about Neanderthals – including their culture, sociality, ecology, diet, control of fire, production and use of tools, physiology, and even their genomic code – than about any other non-human hominin. Here, Spanish researchers use a highly original approach – scientific “role play” – to reconstruct a likely novel element of Neanderthal behavior: cooperating with group members while using fire and tools to catch choughs, birds from the crow family, from their night roosts inside caves. Their findings are published in Frontiers in Ecology and Evolution. Neanderthals are known to have eaten plants, fungi, shellfish, roasted pinecones, and flesh from stranded dolphins. At the same time, they were important […]

Secret to speediness of ancient bipedal reptile has been revealed

By Clarissa Wright, Frontiers science writer Close-up of a reptile eye, but not the ancient Eudibamus cursoris. Image Aedka Studio/Shutterstock.com The Early Permian marked a time of major seasonal changes on the planet, as reptiles rapidly diversified. A key innovation is seen in bolosaurids with the ability to run at high speeds on two legs. Scientists from California State University and Carnegie Museum of Natural History in the US and University of Toronto Mississauga, Canada, collaborated in a study recently published to Frontiers presenting the first comprehensive description of the earliest known bipedal reptile from the Early Permian – a type of bolosaurid called Eudibamus cursoris. For the first time, its unique style of locomotion that achieved high running speeds on two legs has been revealed. The Permian period (between 298.9m and 252.2m years ago) was the last period of the Paleozoic Era. The Earth was warming out of an ice age, while weather intensified. Remnants of carboniferous rainforests disappeared, replaced by open desert. Facing these environmental changes, reptiles rapidly diversified and showed remarkable innovations during the Permian. Bolosaurids are the oldest family belonging to the ancient group of extinct reptiles known as Parareptilla (or parareptiles), and are considered a […]
