Proof that Neanderthals ate crabs is another ‘nail in the coffin’ for primitive cave dweller stereotypes

by Angharad Brewer Gillham, Frontiers science writer Image: Tomasz Ochocki/Shutterstock.com Scientists studying archaeological remains at Gruta da Figueira Brava, Portugal, discovered that Neanderthals were harvesting shellfish to eat – including brown crabs, where they preferred larger specimens and cooked them in fires. Archeologists say this disproves the idea that eating marine foods gave early modern humans’ brains the competitive advantage. In a cave just south of Lisbon, archeological deposits conceal a Paleolithic dinner menu. As well as stone tools and charcoal, the site of Gruta de Figueira Brava contains rich deposits of shells and bones with much to tell us about the Neanderthals that lived there – especially about their meals. A study published in Frontiers in Environmental Archaeology shows that 90,000 years ago, these Neanderthals were cooking and eating crabs. “At the end of the Last Interglacial, Neanderthals regularly harvested large brown crabs,” said Dr Mariana Nabais of the Catalan Institute of Human Paleoecology and Social Evolution (IPHES-CERCA), lead author of the study. “They were taking them in pools of the nearby rocky coast, targeting adult animals with an average carapace width of 16cm. The animals were brought whole to the cave, where they were roasted on coals and […]

‘Many kids go through a phase where they want to be a marine scientist. For me, it wasn’t a phase’

by Patricia Albano/Angharad Brewer Gillham, Frontiers science writer Patricia stands with remotely operated vehicle Deep Discoverer aboard NOAA Ship Okeanos Explorer during an expedition to explore the deep waters off the West Florida Shelf. Image: Patricia Albano. Marine protected areas are meant to give threatened species space to live and thrive. But in a recent paper in Frontiers in Marine Science, Patricia Albano and colleagues showed that at least one protective area isn’t capturing the range that endangered sharks use as they grow, leaving them vulnerable to commercial fishing. Albano, now the Internship Program Coordinator at the National Marine Sanctuary Foundation, NOAA Ocean Exploration, caught up with Frontiers to tell us a little about her career and her research, as part of our Frontiers Scientist series. Albano’s work focuses on shark ecology in an anthropogenic world and the associated conservation implications. After a BA and MSc from the University of Miami, she joined a project evaluating the efficacy of the De Hoop marine protected area (MPA) for threatened and endemic sharks off South Africa. Albano also dedicates her time to working in ocean education, supporting workforce development programs and efforts to increase diversity, equity, inclusion, and accessibility. In 2020, she […]

Medicines that modify the circadian clock might help heal scars more cleanly

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Scientists determined that compounds which play key roles in both collagen synthesis and circadian management can be used to make wounds on cell samples heal more quickly and effectively, offering promise for treatments to prevent problem scarring in the future. Healing often leaves a scar. But the role of the scar itself in healing is often underestimated: a scar that doesn’t heal cleanly can be painful or upsetting or affect the range of movement of the affected body part. It may even require further surgical treatment. Now, scientists based at the University of California Los Angeles have found that compounds which target the circadian clock and affect the synthesis of collagen — a protein which is important for skin repair — could improve scar healing. “Our aim was to find compounds that were able to increase the rate at which dermal wounds heal while mitigating the formation of hypertrophic scars,” said Dr Akishige Hokugo, corresponding author of a study published to Frontiers in Medicine. “Scars can result in emotional distress following normal wound healing by serving as permanent reminders of the initial incident. Accounting for additional revision procedures, extended hospital stays, and […]

Songbird species work together to mob predator owls, but only strike when the time is right

By Mischa Dijkstra, Frontiers science writer Northern pygmy owl, Glaucidium gnoma. Image credit: W Douglas Robinson Scientists have now shown that songbirds don’t just flee from their predator, the northern pygmy owl: they sometimes actively seek them out to aggressively mob them. But the likelihood of mobbing wasn’t constant: it was highest during late summer and autumn when the owls mostly prey on young birds instead of mammals, and at low altitudes, where the owls are most common. The likelihood of mobbing also increased when there were more songbirds around to dilute the individual risk. The authors conclude that songbirds can tell when the risk of predation from northern pygmy owls is greatest, and mostly ignore these owls at other times of the year. Fleeing isn’t the only way by which songbirds can protect themselves against predators. Many songbird species are known to engage in mobbing, where they gather aggressively around a bird of prey, flying rapidly while making stereotypic movements and loud vocalizations. Mobbing is risky for both parties: birds of preys have been observed to attack their mobbers, while cases are known of birds of prey getting injured by mobbing songbirds.

$1 smart glove could help prevent dangerous births by sensing fetal position

by Conn Hastings, science writer Image/Shutterstock.com Low-resource regions often lack the medical technology to assess when things are going wrong during birth. A new study has revealed an inexpensive sensing glove that can transmit data on fetal position and force applied to the fetal head. The technology could be invaluable in identifying obstructed birth in low-resource regions, providing real-time data on a smartphone app. Can inexpensive technologies provide a helping hand during birth? A new study in open-access journal Frontiers in Global Women’s Health has revealed a low-cost sensing glove that could do just that. The researchers created the device to assist healthcare staff in identifying fetal position and the force applied to the fetal head during labor, factors that can contribute to obstructed labor and poor birth outcomes. The technology can provide real-time data during vaginal examinations, potentially improving birth outcomes in low-resource regions. Birth outcomes in low-resource regions When labor is not going as it should, clinicians can use a wide array of medical technologies to determine what is wrong. However, in low- and middle-income countries, these technologies and skilled staff who can use them are not always available. The researchers behind this latest study reported that 98% […]

Using running to escape everyday stresses may lead to exercise dependence instead of mental wellbeing

By Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Different kinds of escapism can motivate people to take part in running, but using running to escape from negative experiences rather than using it to escape to positive ones may lead to exercise dependence. Recreational running offers a lot of physical and mental health benefits – but some people can develop exercise dependence, a form of addiction to physical activity which can cause health issues. Shockingly, signs of exercise dependence are common even in recreational runners. A study published in Frontiers in Psychology investigated whether the concept of escapism can help us understand the relationship between running, wellbeing, and exercise dependence. “Escapism is an everyday phenomenon among humans, but little is known regarding its motivational underpinnings, how it affects experiences, and the psychological outcomes from it,” said Dr Frode Stenseng of the Norwegian University of Science and Technology, lead author of the paper. Running to explore or to evade? “Escapism is often defined as ‘an activity, a form of entertainment, etc. that helps you avoid or forget unpleasant or boring things’. In other words, many of our everyday activities may be interpreted as escapism,” said Stenseng. “The psychological reward from escapism is […]

‘Golden boy’ mummy was protected by 49 precious amulets, CT scans reveal

By Mischa Dijkstra, Frontiers science writer The ‘Golden boy’ digitally unwrapped, stepwise. Image credit: SN Saleem Scientists used CT scans to ‘digitally unwrap’ the approximately 2,300-year-old undisturbed mummy of a teenage boy of high socioeconomic status. The body was equipped with 49 amulets of 21 different types, many of which were made of gold, which had been carefully placed on or inside the body. These included a two-finger amulet next to the uncircumcised penis, a golden heart scarab placed inside the thoracic cavity, and a golden tongue inside the mouth. He was clad in sandals and garlanded with ferns, with ritual significance. This mummy is a showcase of Egyptian beliefs about death and the afterlife during the Ptolemaic period. The ancient Egyptians believed that when we died, our spiritual body sought out an afterlife similar to this world. But entry into this afterlife wasn’t guaranteed: it first required a perilous journey through the underworld, followed by an individual last judgment. For this reason, relatives and embalmers did everything they could to ensure that their loved one might reach a happy destination. Here, scientists from Egypt used computerized tomography (CT) to ‘digitally unwrap’ the intact, never-opened mummy of a 2,300-year-old teenage […]

Microalgae could be the future of sustainable superfood in a rapidly changing world, study finds

By Peter Rejcek, science writer The global population recently hit eight billion people. Yet climate change and human environmental impacts threaten our long-term food security. Researchers at the University of California, San Diego, recently published a scientific review demonstrating that microalgae and other microscopic, plant-like organisms could help feed the world’s growing population more sustainably than current agricultural systems. Algae. It’s what’s for dinner. This variation on the iconic US advertising slogan from the beef industry may sound funny, but it’s no joke that the current agriculture system is a major source of greenhouse gas emissions and environmental pollution. In turn, the climate crisis and ecosystem degradation threaten long-term food security for billions of people around the world. Researchers at the University of California, San Diego (UCSD), believe algae could be a new kind of superfood thanks to its high protein and nutrition content. They make their case in a paper recently published in the journal Frontiers in Nutrition that examines the current scientific literature on microalgae, a catch-all term for the thousands of microscopic algal species and other photosynthetic organisms like cyanobacteria found in various aquatic environments. A more efficient food source The review highlights the current technologies for […]

Rare fossilized feathers reveal secrets of paleontology hotspot during Cretaceous period

by Angharad Brewer Gillham, Frontiers science writer Fossil STM 15-36, photographed by Xuwei Yin at the Shangdong Tianyu Museum of Natural History. Photograph courtesy of the authors. Rare preserved soft tissue – feathers from early Cretaceous birds at Jehol Biota – sheds new light on the world in which they died, millions of years ago. The site of Jehol Biota in China is famous for stunning fossils which preserve soft tissue – skin, organs, feathers, and fur. These fossils offer rare insights into the evolution of characteristics like flight, but they need careful interpretation to understand what the soft tissue looked and behaved like in life, and how decomposition may have affected it. A study published in Frontiers in Earth Science analyzed five fossils of an early Cretaceous bird, Sapeornis chaoyangensis, in order to study how the environment they were buried in changed the preservation of their soft tissue. “Jehol Biota provides the most informative source for understanding Mesozoic ecology,” said corresponding author Dr Yan Zhao, based at the Institute of Geology and Paleontology, Linyi University. “Better understanding of the diverse taphonomy of Jehol terrestrial vertebrates can help us finally understand more about the past and future of biological evolution.” […]

Our toilets can yield excellent alternatives for widespread polluting fertilizers

By Mischa Dijkstra, Frontiers science writer Scientists show that the yield of cabbages grown on soils supplied with two modern nitrified urine fertilizers recycled from human urine is approximately equal to the yield when soils are fertilized with commercial vinasse. The exclusive use of compost recycled from human feces gave a slightly lower yield, but such compost is expected to give extra carbon to soils when combined with nitrified urine fertilizers. Importantly, pharmaceuticals in feces ended up in the edible plant parts only in negligible amounts, implying that fertilizers recycled from human excreta are not only productive but also safe. To tackle the climate crisis, biodiversity loss, and pollution, humanity will need to move to a circular economy, where all resources are recycled. Why not recycle our own body waste too as fertilizer, provided there is no risk that harmful microbes or traces from pharmaceuticals end up in the consumed crops? Most nutrients needed for plant growth occur in human urine and feces. Urine is especially rich in nitrogen and potassium, and also contains trace amounts of metals such as boron, zinc, and iron. Feces could in theory supply other nutrients such as phosphorus, calcium, and magnesium or valuable organic […]

Simple blood test shows promise for screening common and dangerous pregnancy complications

By Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Scientists find that short-chain fatty acids in blood can be used as biomarkers in testing for dangerous pregnancy complications such as pre-eclampsia, gestational diabetes and intrahepatic cholestasis of pregnancy. Scientists at Ningbo University, China have identified biomarkers that could provide an early warning system for three common and dangerous pregnancy complications: pre-eclampsia, gestational diabetes, and a liver condition called intrahepatic cholestasis. All three conditions are dangerous; early diagnosis and treatment is key to preventing poor outcomes and lifelong consequences. Their causes are not fully understood, and nor is their connection to the gut microbiome, which is affected by pregnancy and pregnancy-related conditions. A team led by Dr Siqian Chen at the Affiliated Hospital of Medical School decided to investigate whether specific changes in the microbiome — detected using levels of short-chain fatty acids, metabolites which are produced following the fermentation of microbiota — could be used as biomarkers for pregnancy complications. “We analyzed and correlated the distribution of short-chain fatty acids during normal pregnancy and during three specific types of complicated pregnancy, gestational diabetes, pre-eclampsia, and intrahepatic cholestasis,” said Dr Rongrong Xuan, senior author of the study, published today in Frontiers in […]
