InSight mission: Mars unveils its inner structures
2021-07-22
(Press-News.org) Based on a dozen earthquakes detected on Mars by the SEIS very broadband seismometer, developed in France, the international team of NASA's InSight mission reveals the internal structure of Mars. The three studies published July 23 in Science, involving many co-authors from French institutions and laboratories, including CNRS, the Institut de Physique du Globe de Paris, Université de Paris, and supported by CNES and ANR, reveal, for the first time and thanks to the analysis of seismic waves, reflected and modified by these internal interfaces, an estimate of the size of the core, the thickness of the crust and the mantle structure. This is the first exploration by seismology of the internal structure of a telluric planet other than the Earth and an important step to understand the formation and thermal evolution of Mars.

Study on chromosomal rearrangements in yeast reveals potential avenue for cancer therapy
2021-07-22
Osaka, Japan - Gross chromosomal rearrangements--where portions of the genome become moved, deleted, or inverted--can lead to cell death and diseases such as cancer in complex multicellular organisms. However, the details of how exactly these occur remain unknown. Now, studies in a single-celled organism called fission yeast have found evidence for the involvement of a protein called Rad8.
When DNA replicates or repairs itself, three copies of a protein called PCNA bind together and form a ring-like structure surrounding the DNA strand. This ring structure acts like a clamp and slides along the DNA strand. The team showed that Rad8 attaches ...
Global warming may limit spread of dengue fever, new research finds
2021-07-22
UNIVERSITY PARK, Pa. -- Infection with dengue virus makes mosquitoes more sensitive to warmer temperatures, according to new research led by Penn State researchers. The team also found that infection with the bacterium Wolbachia, which has recently been used to control viral infections in mosquitoes, also increases the thermal sensitivity of the insects. The findings suggest that global warming could limit the spread of dengue fever but could also limit the effectiveness of Wolbachia as a biological control agent.
"Dengue fever, a potentially lethal disease for which no treatment exists, is caused by a virus, spread by the bite of the mosquito Aedes aegypti. This mosquito is also responsible ...
NASA InSight Lander's seismic observations reveal the interior of mars
2021-07-22
NOTICE: This summary has been updated to correct misspellings of the last names of both Perspective authors. The Perspective authors are Sanne Cottaar and Paula Koelemeijer. We apologize for our error.
The first direct seismic observations from NASA's InSight lander, presented in three studies in this issue, provide clues to the composition of Mars. Researchers across these studies report preliminary findings from the Insight mission and begin to map - for the first time - the interior of a planet apart from Earth. "These three studies provide important constraints on the present-day structure of Mars and are also key for improving our understanding of how the planet formed billions of years ago and ...
Trash-bin foragers: Innovation and spread of complex culture in suburban parrots
2021-07-22
In the suburbs of Sydney, Australia, sulphur-crested cockatoos routinely loot lidded household waste bins to scavenge for food. In a new study, researchers document the emergence and geographic spread of innovative bin-opening behaviors in urban parrot populations, revealing the presence of a complex social learning culture in these birds. What's more, this behavior appears to have emerged as a direct response to land-use change and urbanization, demonstrating how animal cultures could allow for local adaptation of urban animal populations in the Anthropocene. In animals, ecological novelty, including novelties unique ...
A case for intranasal COVID-19 vaccinations
2021-07-22
Of the nearly 100 SARS-CoV-2 vaccines currently undergoing clinical trials, only seven are delivered intranasally - despite this vaccine type's long success in providing protection from influenza. In a Perspective, Frances Lund and Troy Randall argue that intranasal vaccines could be beneficial in the continued fight against COVID-19, especially considering respiratory viruses like SARS-CoV-2 predominantly enter the nasal passage first. Currently authorized COVID-19 vaccines are delivered via intramuscular injection, where they elicit systemic immune responses and central immune memory. While several ...
Spontaneous retinal waves simulate optical flow before neonatal mice can see
2021-07-22
Like dreaming of walking through a world they've not yet experienced, the retinas of neonatal mice practice for what mature eyes must later process by generating spontaneous patterns of activity that mimic the perception of directional movement through space, according to a new study. Essential functions in the mammalian visual system, including the ability to locate objects and detect motion, are present even at the first onset of vision. Optic flow, the perceived relative motion of objects and surfaces that seemingly stream by a field of vision during movement, is one of these functions. However, how the visual system organizes its functional characteristics before visual sensory experience is even possible remains unclear. ...
Mars: Scientists determine crustal thickness
2021-07-22
Based on the analysis of marsquakes recorded by NASA's InSight mission, the structure of Mars's crust has now been determined in absolute numbers for the first time. Beneath the InSight landing site, the crust is either approximately 20 or 39 kilometres thick. That is the result of an international research team led by geophysicist Dr Brigitte Knapmeyer-Endrun at the University of Cologne's Institute of Geology and Mineralogy and Dr Mark Panning at Jet Propulsion Laboratory, California Institute of Technology (Caltech). InSight stands for 'Interior Exploration using Seismic Investigations, Geodesy and Heat Transport'. NASA's lander, which ...
Global approach is needed on battery regulation
2021-07-22
New European Union regulations on batteries could offer a huge boost to the global decarbonisation mission - but only if it leverages its political and economic weight to ensure a fairer global marketplace.
According to a team of scientists and researchers writing in Science, the new regulations, due to come into force from January 2022, have the potential to unify policy on approaches such as recycling, use of recycled raw materials, and creating a circular economy.
Contributing to the study were experts at Newcastle University, the University of Birmingham, Circular Energy Storage Research and Consulting, ...
Eyes wide shut: How newborn mammals dream the world they're entering
2021-07-22
As a newborn mammal opens its eyes for the first time, it can already make visual sense of the world around it. But how does this happen before they have experienced sight?
A new Yale study suggests that, in a sense, mammals dream about the world they are about to experience before they are even born.
Writing in the July 23 issue of Science, a team led by Michael Crair, the William Ziegler III Professor of Neuroscience and professor of ophthalmology and visual science, describes waves of activity that emanate from the neonatal retina in mice before their eyes ever open.
This activity disappears soon after birth and is replaced by a more mature network of neural transmissions ...
InSight mission: Mars unveiled
2021-07-22
Using information obtained from around a dozen earthquakes detected on Mars by the Very Broad Band SEIS seismometer, developed in France, the international team of NASA's InSight mission has unveiled the internal structure of Mars. The three papers published on July 23, 2021 in the journal Science, involving numerous co-authors from French institutions and laboratories, including the CNRS, the Institut de Physique du Globe de Paris, and Université de Paris, and supported in particular by the French space agency CNES and the French National Research Agency ANR, provide, for the first time, an estimate of the size of the planet's core, the thickness of its crust and the structure of its mantle, based on the analysis of seismic waves reflected ...
