Modelling shows urgent need to revamp hiring and working conditions for astronomers2h
It will take until at least 2080 before women make up just one-third of Australia's professional astronomers, an analysis published today in the journal Nature Astronomy reveals.
Brazil's economic crisis, prolonged by COVID-19, poses an enormous challenge to the Amazon2h
Brazilian President Jair Bolsonaro confirmed his country's participation in a virtual climate summit convened by the U.S. for April 22 and 23, vowing in a recent letter to U.S. President Joe Biden to end illegal deforestation in Brazil by 2030—a striking about-face from a longtime adversary to the country's environmental policies.
Brain mapping: explained2h
Brain mapping is an attempt to identify the location of everything in the brain. An accurate map of the brain would immeasurably enhance our ability to understand how it works. The project is massive, involving multiple fields of biomedical research and expensive cutting-edge technology. Brain mapping is one of the hottest current areas of research. The brain is nothing short of amazing. Billions
Patients who are obese or overweight are at risk for a more severe course of COVID-192h
COVID-19 patients who are overweight or obese are more likely to develop a more severe infection than patients of healthy weight, and they require oxygen and invasive mechanical ventilation more often. There is no increased risk of death . These conclusions, for which more than 7,000 patients were studied, appear from international research in eleven countries, including the Netherlands (Radboud u
MIPT and Harvard researchers grow stem cells to cure glaucoma2h
A joint research carried out by MIPT scientists and Harvard researchers have presented retinal cells that can integrate into the retina. This is the first successful attempt to transplant ganglion cells (retinal neurons that are destroyed by glaucoma) derived from stem cells in a lab setting. Scientists tested the technology in mice and established that the cells successfully integrated and surviv
Mapping performance variations to see how lithium-metal batteries fail2h
Scientists have identified the primary cause of failure in a state-of-the-art lithium-metal battery, of interest for long-range electric vehicles: electrolyte depletion.
Can we learn to talk to sperm whales? | David Gruber2h
Animals are communicating — but what are they saying? And can we talk back? Marine biologist David Gruber introduces Project CETI: a team of scientists, linguists and AI specialists hoping to decode sperm whale language. Using noninvasive robots and a machine-learning algorithm to collect and analyze millions of sperm whale vocalizations known as coda, the team aims to demystify the communication
Smallest stegosaur footprint ever came from cat-sized dino2h
Researchers have discovered a single footprint left by a cat-sized dinosaur around 100 million years ago in China. "This footprint was made by a herbivorous, armored dinosaur known broadly as a stegosaur—the family of dinosaurs that includes the famed stegosaurus," says Anthony Romilio, a researcher from the University of Queensland who was part of the team that investigated the track. "Like the
New Electron Tricks in Synthetic Chemistry2h
One of specialties of Phil Baran's group at Scripps the last few years has been electrosynthesis, which has a traditional hmm-interesting-turn-the-page reputation among most synthetic chemists that they're trying to change . Photochemistry was in roughly the same category at one time, and has become much more mainstream (although it always had an advantage with lower barrier to entry). That field
Ämnesomsättning och sömn kopplat till ALS2h
ALS-patienter har sjukdomsförändringar i de hjärnceller som tillverkar ämnen som reglerar ämnesomsättning och sömn. Det visar en grupp forskare i Lund och Australien. Fynden ger ökad kunskap om sjukdomens bakomliggande orsaker och kan förhoppningsvis på sikt bidra till nya behandlingar. Vanliga symtom vid ALS, amyotrofisk lateral skleros, är en smygande muskelsvaghet som sprider sig till olika de
Cotton wool proves effective in separating single-wall carbon nanotubes2h
Carbon nanotubes (CNT) are a family of 1D nanostructures with numerous verified applications, made possible due to their excellent mechanical, optical and conductive properties. However, application of CNTs is hampered by the presence of species with various structures in the raw production mixture, which obscures unique properties of individual species.
Consumers will pay more for crowdfunded products to boost equality in marketplace2h
New research has revealed that shoppers are significantly more likely to purchase crowdfunded products than items that use an alternative funding source, as they want to see less inequality in the marketplace.
Modeling collisions between argon nuclei and neutrinos from a supernova2h
Massive stars end their lives in explosions called core-collapse supernovae. These explosions produce very large numbers of weakly interacting particles called neutrinos. Scientists working on the Deep Underground Neutrino Experiment, hosted by Fermilab, are seeking to perform a detailed measurement of supernova neutrinos. This effort could lead to groundbreaking discoveries in particle physics an
Evidence for glaciation predating MIS-6 in southeastern Tibet2h
Southeastern Tibet is one of the most glaciated regions on the Tibetan Plateau both at present and during the Quaternary. Numerical dating of glacial deposits has allowed the establishment of a provisional chronology of Quaternary glacial fluctuations in this region, with the oldest glaciation (Guxiang Glaciation) occurring in marine oxygen isotope stage 6 (MIS-6). However, glaciations predating M
Where's my horse-sized rabbit?2h
Next to cat videos, watching small and cuddly rabbits is probably one of the most popular internet pastimes. Plus they appear in literature as well as in traditional folklore spanning numerous cultures, thanks likely to the fact that rabbits reside on every continent except Antarctica.
Human land-use and climate change will have significant impact on animal genetic diversity2h
Over the last 200 years, researchers have worked towards understanding the global distribution of species and ecosystems. But so far even the basic knowledge on the global geography of genetic diversity was limited.
Where are the women on the Spanish-language Wikipedia site?2h
With its more than 40 million articles in 301 different languages, Wikipedia is one of the largest human collaboration efforts in history. One of the main pillars on which this wish to bring together the sum of all knowledge is based is the achievement of a neutral space. However, several studies suggest that the site suffers from a persistent gender bias as regards both content and the compositio
To forget or to do not forget?2h
Alzheimer's disease (AD) is a form of progressive dementia interfering with daily living. It is caused by the decline in the number of brain cells resulting in the deterioration of our mental abilities. One of the main reasons for the worsening brain cells condition and even the brain shrinkage are molecules having a specific structure called β-amyloids. They are peptides that tend to agglomerate
Ice cap study promises new prospects for accurate local climate projections2h
New, detailed study of the Renland Ice Cap offers the possibility of modelling other smaller ice caps and glaciers with much greater accuracy than hitherto. The study combined airborne radar data to determine the thickness of the ice cap with on-site measurements of the thickness of the ice cap and satellite data. Researchers from the Niels Bohr Institute – University of Copenhagen gathered data f
Russian scientists discover a new gene regulation mechanism2h
A team of scientists from Russia studied the role of double-stranded fragments of the maturing RNA and showed that the interaction between distant parts of the RNA can regulate gene expression.
Army researchers create pioneering approach to real-time conversational AI
Spoken dialogue is the most natural way for people to interact with complex autonomous agents such as robots. Future Army operational environments will require technology that allows artificial intelligent agents to understand and carry out commands and interact with them as teammates.
