By Colm Gorey, Frontiers science writer Image: Thiago B Trevisan/Shutterstock.com The aviation sector is seen as a very visible contributor of CO2 emissions globally, but will efforts to clean up the industry pay off? New research published with Frontiers has calculated what impact ‘sustainable aviation fuel’ (SAF) will have, showing CO2 emissions between 4% and 23% lower than if no SAF was used, even if airlines exceed pre-Covid-19 demand. However, while the use of SAF can help contribute to international targets, SAF alone will not be enough to meet 2050 net-zero CO2 goals for aviation. Much in the same way that the automotive industry is shifting gears to produce more environmentally-friendly cars to offset the effects of the climate crisis, the aviation sector is trying to find ways to significantly cut down on its CO2 emissions. Estimates suggest that the sector is responsible for about 2.5% of global carbon emissions and equivalent to the release of more than 900m metric tons of CO2 annually just prior to the Covid-19 pandemic. However, with entirely electric-powered aircraft some way off from becoming commonplace and limited in range, airlines have turned to cleaner jet fuels to help reduce their impact on the planet […]

By Mischa Dijkstra, Frontiers science writer During parabolic flight to simulate weightless conditions in space, researchers show for the first time that a DNA polymerase enzyme derived from bacteria makes 10-140% more errors while copying DNA in microgravity. Combined with the known greater rate of DNA damage from space radiation, this inaccuracy of DNA replication is likely to pose a threat to the health of future astronauts on long missions. On 22 May 2019, scientists from Queen’s University boarded a modified Falcon 20 aircraft at Ottawa airport. Scheduled was a ‘vomit comet’ flight, where the plane repeatedly climbs to 8km in a steep parabola, alternating with a descent in freefall. During freefall, at a rate of over 3.3km in 20 seconds, only gravity but no lift, thrust, or drag work on the plane, resulting in weightlessness. The scientists’ mission under these difficult conditions was to test whether the enzymes that copy DNA are as accurate under weightlessness as under earthbound conditions. This question is of paramount importance for future space exploration, as the health of astronauts will depend on accurate DNA replication during cell division. “So-called DNA polymerases are essential enzymes that copy and repair DNA. Inevitably, they aren’t perfect: […]

By Peter Rejcek, science writer Image credit: Diego Cervo / Shutterstock.com Binge-watching is a modern phenomenon where TV viewers sit through two or more episodes of a series at one time. A growing body of research suggests there may be negative consequences to this behavior, similar to other addictive activities such as online gaming. Now, a new study has identified what personality traits and motivations may predict problematic binge-watching. Impulsivity and the motivation to escape are among the most significant factors that drive marathon viewing. Once upon a time, TV viewers had to wait patiently each week for a new episode of their favorite series to drop. Streaming services have upended that model, allowing unfettered access to an entire season-worth of episodes – unleashing the phenomenon known as binge-watching. Recent research into the behavior suggests it may be similar to other addictive activities, for example online gaming. A new study published in the journal Frontiers in Psychiatry identified what factors may help predict unhealthy binge-watching. While marathon viewing of multiple TV episodes has been around for decades, binge watching burst onto the scene with the popular streaming service Netflix. Since then, it has become a popular way to spend free […]

By K.E.D. Coan, science writer Electroconvulsive therapy may be one of the most effective treatments for depression and severe mental conditions. But ongoing stigma associated with this therapeutic approach prevents it from being used more frequently. A recent study published in Frontiers in Psychology shows that, at least for one treatment center in Germany, the rate of life-threatening adverse events is less than 0.1%, suggesting that the medical community can safely use the method more broadly. The safety concerns associated with electroconvulsive therapy (ECT) are unwarranted, according to a new study in Frontiers in Psychology. In part due to historical misuse and cinematic portrayals such as in One flew over the cuckoo’s nest, physicians and patients have been reluctant to use this approach. But extensive evidence appears to show that ECT may be one of the most valuable and effective options for severe and treatment-resistant mental conditions such as schizophrenia and depression. This latest study of more than 3,100 ECT sessions in a German psychiatric hospital appears to confirm that ECT is also very safe. There were no cases of permanent impairments from the treatment and only three sessions (<0.1%) caused potentially life-threatening events, which were all resolved by medical […]

By Dr Emma K Grigg, University of California, Davis Dr Emma K Grigg, University of California, Davis. Image: Sherri Rieck We may not realize it, but many household appliances are causing our pets significant stress, according to a new study published in Frontiers in Veterinary Science. Now, one of its authors, Dr Emma K Grigg of University of California, Davis, writes about another less-discussed issue: how little effort is being put into better understanding our pets. Grigg is a certified applied animal behaviorist and a staff research associate and lecturer at the University of California, Davis, School of Veterinary Medicine. She is also a lecturer in canine behavior at Bergin University of Canine Studies in northern California and has authored a number of scientific publications on canine, feline, and marine mammal behavior. Her first book, The Science Behind a Happy Dog, was published in June 2017. As an animal behavior researcher who specializes in dogs and cats, I have been trained to carefully observe and interpret their body language to better understand and predict their behavior, to study the ways in which they interact with their worlds, and to continually consider the impacts of human activities on their wellbeing.

By Colm Gorey, Frontiers science writer Image: SciePro/Shutterstock.com Future planetary colonists will experience isolation like no other group in human history, which is why scientists on Earth are attempting to see how we communicate in the most extreme situations. In a paper published with Frontiers, researchers in Russia observed volunteers in isolation attempting to replicate life in deep space to see how it would impact their mood and communication styles. Despite some initial differences, the eventual cohesion of the team offers hope for future moon and Mars colonists. Elton John famously sang that Mars “ain’t the kind of place to raise your kids”, but one day space agencies across the globe hope to prove him wrong by seeing the first human establishing the first colony on the Red Planet, and elsewhere in the solar system. However, those who make the journey will not only have to survive on a freezing planet with no breathable atmosphere, but live in isolation unlike any other explorers in human history. At its closest proximity, Mars is still almost 55m km away from Earth, making communication delays and supply issues between the two worlds unavoidable. This requires crew members to effectively cope with stressful conditions […]

By Mischa Dijkstra, Frontiers science writer Image credit: By Stefan_Sutka / Shutterstock.com Mice who inhale CO2 within hours after forming a new fearful memory show more distress when subsequently prompted to retrieve the memory. This memory-strengthening effect of CO2 requires a functional ASIC1A gene in the mouse brain. The effect is time-dependent, unique to CO2, and specific to only certain types of memories, such as fearful sound cues or environmental contexts. Memories of a different type, such as remembering familiar objects, are weakened rather than strengthened by CO2. The inhalation of carbon dioxide (CO2) by mice a few hours after they formed a new fearful memory makes that memory stronger, so that the mice show more distress when they are prompted to ‘retrieve’ (ie, recall) it. That is the conclusion of a recent in Frontiers in Behavioral Neuroscience by neuroscientists from the University of Iowa, US. The authors also show that the memory-strengthening effect of CO2 only occurs when the gene acid-sensing ion channel-1a (ASIC1A) is functional in the mouse brain. If the human version of the ASIC1A gene proves to have a similar role in the formation of fearful memories, interventions targeting this molecular pathway could one day be a […]

Image: Corona Borealis Studio/Shutterstock.com Have you ever asked yourself what is it in our brains that actually helps us navigate in the world? Helping us answer that question, Prof May-Britt Moser won the Nobel Prize in Physiology or Medicine in 2014 for the discovery of cells that constitute a positioning system in the brain. When you think about navigation, what is the first thing that comes to mind? Is it the well-known GPS system in your cellphone? An underwater journey of a submarine to its destination? Or perhaps a team assignment in the scouts, to find your way back to the camp at night? Would you be surprised to know that our brains have a built-in navigation system responsible for representing our location in the environment and for orienting us so that we can successfully get from one place to another? This mental representation of the environment is often called a cognitive map and was the focus on a Nobel prize-winning paper published by Prof May-Britt Moser. ► Read and download (pdf) of original article While navigation in the environment appears seamless and automatic, the brain’s navigation system is actually quite complex, composed of several brain regions and various cells types.

By Colm Gorey, Science Communications Manager 3D rendered medically accurate illustration of a cancer cell (not representative of what’s seen using singlecellVR). Image: SciePro/Shutterstock A team of scientists has developed a free, open-access VR program that allows anyone to interact with single-cell datasets using a headset costing less than $10. Previous tools used to view single-cell data visualizations in VR have been limited to the most expensive hardware, costing upwards of $2,500. The team’s findings have been published in Frontiers in Genetics. While often thought of as being limited to expensive hardware for dedicated gamers, virtual reality (VR) has become a lot more affordable in recent years with entry-level hardware – such as Google Cardboard – costing less than $10. With this headset, anyone with a smartphone can place their device into the headset and view VR content through its large screen. With the barrier to entry now greatly reduced, scientists and engineers are trying to figure out ways of bringing VR to the masses and, potentially, using it to unlock breakthrough discoveries. One such team of researchers from some of the US’s top medical centers and institutions has now published a paper in Frontiers in Genetics documenting a VR […]
