Solar energy is superior to nuclear for powering crewed mission to Mars, show scientists

By Peter Rejcek, science writer A crewed mission to Mars will require transporting equipment for creating electricity to power life support systems. The choice for the type of device used will require a tradeoff between mass and energy efficiency. Researchers here show that a photovoltaic system using compressed hydrogen energy storage can compete with nuclear energy across about 50% of the Red Planet. No other planet in our solar system has sparked the human imagination more than Mars. While modern science has debunked the Red Planet as a likely source of an alien invasion, today’s technology is bringing us closer to a crewed mission. A research team out of the University of California, Berkeley published a paper in the journal Frontiers in Astronomy and Space Sciences that argues a human expedition on the surface could be powered by harvesting solar energy. The concept is not new. The main source of power for some NASA Mars rovers comes from a multipanel solar array. But, in the last decade or so, most people had assumed that nuclear power would be a better option than solar energy for human missions, according to co-lead author Aaron Berliner, a bioengineering graduate student in the Arkin […]

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 […]

World Malaria Day: Meet a researcher using genetic engineering to tackle a serious global disease

By Colm Gorey/Prof Tania de Koning-Ward, Deakin University Prof Tania de Koning-Ward, Deakin University. Image: Deakin University World Malaria Day – held on the 25 April –  is an occasion to highlight the need for continued investment and sustained political commitment for malaria prevention and control. To mark this important awareness day, Frontiers caught up with Prof Tania de Koning-Ward to hear how she is contributing to a global effort to prevent hundreds of thousands of deaths each year. Tania de Koning-Ward is a professor in molecular microbiology based at Deakin University’s School of Medicine in Australia and is a senior research fellow of the country’s National Health and Medical Research Council. Here she heads the school’s malaria pathogenesis research group which aims to investigate molecular level, key parasite-host interactions that enable malaria parasites to thrive and survive in their host and cause disease. She has published extensively on the subject, including in an article published to Frontiers in Cellular and Infection Microbiology in September 2020. What inspired you to become a researcher? Do you have any specific memories that set off a spark? Growing up, I always enjoyed biology and maths but realized pretty quickly at university that it […]

Most read articles of March 2022: Secrets of ancient leftovers revealed and endangered shark discovered in pet food

By Colm Gorey, Science Communications Manager, Frontiers 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 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 […]

People married into long-lived families share lower risk of type II diabetes

By Mischa Dijkstra, Frontiers science writer New study within the US Long Life Family Study identifies biomarkers characteristic for people born in – or married into – families with exceptionally long-lived members. Both groups also have a reduced risk of developing type II diabetes. Sharing the household and lifestyle of children of long-lived parents might lead to these marked health benefits for spouses, but it’s also possible that people tend to pick their partners through ‘assortative mating’, matching phenotypes and genotypes for healthy aging and longevity. What makes some people predisposed to live and remain healthy much longer than others? That some persons reach an exceptional age has been recorded throughout history. It’s tempting to write down such outliers as only the result of environment and behavior: for example, better-than-average nutrition, medical care, childcare practises, and hygiene, not to mention luck. But as average life expectancy continues to increase worldwide due to overall improvements in these and other factors, it’s becoming clear that exceptional longevity and healthy aging tend to run in families. This suggests that genetic differences also play a role in assuring lifespan and life-long good health. Prof Iva Miljkovic from the School of Public Health at the […]

The hidden effects of deforestation on our planet and 3 other fascinating Frontiers articles you may have missed

By Colm Gorey, Frontiers 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. 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 […]

Last of the giant camels and archaic humans lived together in Mongolia until 27,000 years ago

By Mischa Dijkstra, Frontiers science writer Camelus knoblochi would have dwarfed the modern domestic Bactrian camel, Camelus bactrianus, which also has two humps. Image credit: Bandurka/Shutterstock.com This is the first report of fossils of a species of giant camel, Camelus knoblochi, from today’s Mongolia. The author show that the species’ last refuge in the world was in Mongolia until 27,000 years ago. There, they coexisted with archaic humans and the much smaller wild Bactrian camel C. ferus. Climate changing leading to desertification and possibly hunting by humans and competition with C. ferus drove C. knoblochi into extinction. A species of giant two-humped camel, Camelus knoblochi, is known to have lived for approximately a quarter of a million years in Central Asia. A new study in Frontiers in Earth Science shows that C. knoblochi’s last refuge was in Mongolia, until approximately 27,000 years ago. In Mongolia, the last of the species coexisted with anatomically modern humans and maybe the extinct Neanderthals or Denisovans. While the main cause of C. knoblochi’s extinction seems to have been climate change, hunting by archaic humans may also have played a role. “Here we show that the extinct camel Camelus knoblochi persisted in Mongolia until climatic […]
