5 articles you need to check out on the future of materials research

By Angharad Brewer Gillham, Frontiers science writer Image: Shutterstock.com In a fast-moving field of research like materials science, it can be difficult to keep up with the latest breakthroughs. Now at Frontiers, we highlight just five of the latest research articles to shed more light on the way we build our world around us, published by top researchers in the Frontiers in Materials Research Topic ‘Horizons in Materials’. Growing green technology: from trees to tech Scientists aiming to power the appliances of the future are developing special phenolic compounds from resins instead of petrol – a first step towards organic electrodes. Since biomass is the only green, renewable source of carbon materials, carbon-based electrodes for new-generation metal-ion batteries could be a more eco-friendly replacement for lithium-ion batteries. Some of the methods to make these compounds currently available are problematic because they require dangerously high temperatures and pressures and hazardous chemicals, but new methods are being developed which use mechanical forces instead. If these compounds can be developed into renewable sources for electronics, Dr Javier Quílez-Bermejo and his team at the Université de Lorraine point out, the potential for revolutionizing electronic devices would be huge, opening the way for greener fuel […]

From ghost gear to microbe memories: 4 Frontiers articles you won’t want to miss

by Angharad Brewer Gillham, Frontiers science writer 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. The hunt for ghost gear 25-30% of the plastic waste in the sea is lost fishing gear, or ‘ghost gear’, some of it now up to 60 years old. This ghost gear devastates the environment not only through continuing to trap fish, but also by shedding microplastics into the environment which then enter the food chain. Once it sinks as far as the sea floor, it becomes invisible from above – a hidden threat to the marine ecosystem. A team led by Andrea Stolte from the World Wildlife Foundation, writing in Frontiers in Marine Science, reported a successful ghost-hunting collaboration between fisherfolk, scientists, and divers in the Baltic Sea. This coalition of stakeholders had several options for hunting down the ghost gear. Traditionally, when lost gear is spotted, fisherfolk use search hooks and other similar tools to try to retrieve it. However, this proved to be inefficient and damaging to the […]

From chili-heat pain relief to blue whale migration: 5 Frontiers articles you won’t want to miss

by Angharad Brewer Gillham, Frontiers science writer 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 five amazing papers you may have missed. Chili to the rescue: Modulating capsaicin as a treatment for chronic itching Pain and itching are both signals that help humans protect themselves, by prompting us to end contact with whatever causes us pain or make us itch. However, they are also key symptoms of many disorders, and can be frustratingly difficult to treat. Scientists from the Universidad Miguel Hernández, writing in Frontiers in Molecular Neuroscience, investigated whether transient receptor potential channels, which pick up sensory cues ranging from the taste of wasabi to changes in pH, could help treat pain and itching. Previous attempts to exploit these channels to stop pain and itching have not been successful because they cause overheating as a side effect, so the authors suggested that ‘soft’ modulation of the channels might be more patient-friendly, targeting only the channels that aren’t working correctly. While there are several existing medications which use capsaicin to target these channels, […]

Scientists eavesdrop on minke whale ‘boing’ calls in Hawai’i, and 4 other articles you don’t want to miss

By Angharad Brewer Gillham, Frontiers science writer Image: Annie Leblanc/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 five amazing papers you may have missed. Scientists eavesdrop on minke whale conversations in Hawai’i Scientists writing in Frontiers in Marine Science used hydrophones to study hard-to-spot minke whales in Hawai’i, learning that they use their ‘boing’ calls more frequently when they are close to other members of the same species. Minke whales who visit this area are hard to study because they are small, solitary, and visit outside the times when most ship-based surveys are conducted. Passive acoustic monitoring, using hydrophones mounted on the sea bed, allows scientists to listen in on whales all year round. The authors used 47 hydrophones to record thousands of calls between 2012 and 2017. These calls were analyzed to detect individual whales and monitor their behavior in the study area. The minke whales used their ‘boing’ calls only between fall and spring, and called more rapidly when other minke whales were nearby. Because minke whales are so enigmatic, it isn’t […]

Researchers challenge claim of historic human brain ‘shrinking’ and 3 other papers you don’t want to miss

By Colm Gorey and Mischa Dijkstra, Frontiers science writers 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 five amazing papers you may have missed. Researchers challenge idea that human brains shrank 3,000 years ago Last year, an article published to Frontiers in Ecology and Evolution made headlines across the world after it claimed human brains shrank in size approximately 3,000 years ago. This, according to the authors, may have driven by the externalization of knowledge in human societies, thus needing less energy to store a lot of information as individuals. As a result, we developed smaller brains. However, in a recent article, also published to Frontiers in Ecology and Evolution, another team of researchers challenged this notion, questioning several of the original paper’s key hypotheses. Speaking to his university, the University of Nevada, Las Vegas, anthropologist Brian Vilmoare said that “human brain size has not changed in 30,000 years, and probably not in 300,000 years”. In fact, he added, “based on this dataset, we can identify no reduction in brain size in modern […]

Key to life found at the centre of our galaxy and bee ‘waggle dances’: Most viewed articles of July 2022

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 July. Building blocks for RNA-based life abound at center of our galaxy Nitriles, a class of organic molecules with a cyano group, that is, a carbon atom bound with an unsaturated triple bond to a nitrogen atom, are typically toxic. But paradoxically, they are also a key precursor for molecules essential for life, such as ribonucleotides, composed of the nucleobases or ‘letters’ A, U, C, and G, joined to a ribose and phosphate group, which together make up RNA. Now, a team of researchers from Spain, Japan, Chile, Italy, and the US show in Frontiers in Astronomy and Space Sciences that a wide range of nitriles occurs in interstellar space within the molecular cloud G+0.693-0.027, near the center of the Milky Way.

But with tens of thousands of articles published each year, many often fly under the radar. Here are just five amazing papers you may have missed. Impact of Alzheimer’s on the brain may be greater than previously thought A significant review of more than 200,000 scientific publications has shown that the effects of Alzheimer’s disease on the brain are far broader than initially thought. Writing in their review article in Frontiers in Aging Neuroscience, the international team of researchers said that they wanted to understand the breadth and diversity of biological pathways – key molecular chain reactions that drive changes in cells – that contribute to Alzheimer’s disease by research over the last 30 years. They found that while nearly all known pathways have been linked to the disease, the most frequently associated biological mechanisms have not significantly changed in the last three decades, despite major technological advances. These include those related to the immune system, metabolism, and long-term depression. They also found that the top-ranked 30 pathways most frequently referred to in literature remained relatively consistent […]

But with tens of thousands of articles published each year, many often fly under the radar. Here are just five amazing papers you may have missed. Daily eating of cranberries may give us a memory boost and lower ‘bad’ cholesterol The famous proverb says that an apple a day keeps the doctor away, but a recent study published to Frontiers in Nutrition has found that significant health benefits may come from eating a cup of cranberries a day. A team of researchers from the UK, the Netherlands, and Italy set out to see what benefits this daily dose of the popular berry would have on those aged between 50 and 80. Of those taking part in the study, half ate freeze-dried cranberry powder equivalent to 100g of fresh cranberries, while the other half were given a placebo. The results showed that those who were eating cranberries daily saw a significant improvement in their memory of everyday events, neural functioning, and delivery of blood to the brain. The researchers hope that their findings could have implications for […]

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 […]

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 – […]

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 […]

Now, as part of new series each month, Frontiers will highlight just some of those amazing papers you may have missed. The Unseen Effects of Deforestation: Biophysical Effects on Climate Research published to Frontiers in Forests and Global Change offers the most comprehensive and detailed evidence to date that forests are more important to the climate – both globally and locally – than we think due to the way in which they physically transform the atmosphere. The first-ever research conducted by a team from the US pinpointed the local, regional and global non-CO2 benefits of specific forest zones worldwide to find that the entire world gains the most benefits from the band of tropical rainforests spanning Latin America, central Africa and Southeast Asia. It finds that, together, forests keep the planet at least half of a degree Celsius cooler when we account for the understudied biophysical effects – from chemical compounds to turbulence and the reflection of light. These effects in […]

Here are just some of the highlights that resonated strongly with readers on our news site in the month of February. A replay of life: What happens in our brain when we die? Imagine reliving your entire life in the space of seconds. Like a flash of lightning, you are outside of your body, watching memorable moments you lived through. This process, known as ‘life recall’, can be similar to what it’s like to have a near-death experience. What happens inside your brain during these experiences and after death are questions that have puzzled neuroscientists for centuries. However, a new study published to Frontiers in Aging Neuroscience suggests that your brain may remain active and coordinated during and even after the transition to death, and be programmed to orchestrate the whole ordeal.

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 […]

Here are just some of the highlights that resonated strongly with readers on our news site in the month of January. Likely energy source behind first life on Earth found ‘hiding in plain sight’ Life on Earth arose roughly 4bn years ago. How it arose, and from what energy source is of interest to everyone because we humans like to know where we come from. The team of Prof William Martin at the University Düsseldorf’s Institute of Molecular Evolution investigates early evolution. In a recent paper in Frontiers in Microbiology, they argue that the source of energy required at life’s origin has been hiding in plain sight: under the environmental conditions at deep sea hydrothermal vents, hypothesized to have been the sites where life on Earth originated, the central biosynthetic reactions of life do not require an external energy source.
