The amount of long-lived radioactive elements incorporated into a rocky planet as it forms may be a crucial factor in determining its future habitability, according to a new study by an interdisciplinary team of scientists at UC Santa Cruz.
That's because internal heating from the radioactive decay of the heavy elements thorium and uranium drives plate tectonics and may be necessary for the planet to generate a magnetic field. Earth's magnetic field protects the planet from solar winds and cosmic rays.
London, UK (10 Nov 2020) -- The observance of Lung Cancer Awareness Month in November affords an opportunity to take stock of current approaches to lung cancer research, and to cancer research more widely. While there have been improvements in understanding, prevention and overall survival, it is still shocking to note that more than 1.7 million people died of lung cancer in 2018 alone This is the case despite the fact that lung cancer research has been relatively well-funded, and this suggests that an urgent need to rethink how we prioritise the funding available for cancer research.

Our planet's coral reef ecosystems are in peril from multiple threats. Anthropogenic CO2 has sparked a rise in global average sea surface temperatures, pushing reef survival beyond its upper thermal limits. Coastal development from industry, aquaculture, and infrastructure generates sedimentation and increased turbidity in coastal waters, which raises particulate organic carbon (POC) levels. Additionally, sedimentation reduces photosynthetically active radiation (PAR), the much-needed sunlight soaked up by the symbiotic algae corals rely on for food.
Delayed growth, craniofacial dysmorphism, skeletal abnormalities, moderate intellectual disability and, often, congenital heart defects. This is how the Kabuki syndrome manifests itself, a rare genetic disease, which has an incidence of one case in every 30,000 births.
MADISON, Wis. -- Coral reefs are vibrant communities that host a quarter of all species in the ocean and are indirectly crucial to the survival of the rest. But they are slowly dying -- some estimates say 30 to 50 percent of reefs have been lost -- due to climate change.
New York, NY--November 9, 2020--Computer scientists at Columbia Engineering have shown for the first time that it is possible to analyze how thousands of Android apps use cryptography without needing to have the apps' actual codes. The team's new tool, CRYLOGGER, can tell when an Android app uses cryptography incorrectly--it detects the so-called "cryptographic misuses" in Android apps.
Famous Catalan architect Antoni Gaudí once said, "Anything created by human beings is already in the great book of nature." Among different man-made architectures and art, spherical structures and shapes have been the most fantastical geometrical form that fascinated the figments of the human imagination. Making perfect spherical architectures is challenging due to their geometric purity and technical complexity and therefore these structures are both enchanting as well as rare.
A research team has developed a new method for creating metal-organic framework (MOF) thin films that can be applied to sensors and electric devices.
Like sponges, porous materials contain pores. The pore size affects the property of the material. For example, small pores create more absorbent surface areas. Silica gel, which is often used in food packaging to soak up moisture, is one typical example.
Social distancing introduced in response to COVID-19 is increasing feelings of loneliness in Scotland's older population and impacting their wellbeing, according to a new University of Stirling study.
The research has identified a link between increases in loneliness in over 60s and the worsening of wellbeing and health. Increasing loneliness due to social distancing was associated with a smaller social network, lower perceived social support and a decrease in wellbeing, the study found.
In order to escape predators, many fish - including insects, fish and birds - have developed strategies for rapidly transmitting information on threats to others of their species. This information is transmitted within a group of hundreds, or even thousands, of individuals in (escape) waves. This collective response is also, in the case of fish, known as shoal behaviour. Special parasites can, however, manipulate such a survival strategy.
ADELPHI, Md. -- Army scientists developed computer-based training to help Soldiers avoid unnecessary social conflict and mitigate anger-related outcomes.
The Earth is getting warmer at a faster rate than ever. 93% of the net energy is absorbed by global ocean surface in the form of the Ocean Heat Uptake (OHU), which is the key factor modulating the rate of global warming.
The Southern Ocean (surrounding the Antarctic continent, south of 30°S ) plays a dominant role in global OHU while the North Atlantic takes a small share.
UPTON, NY--Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Stony Brook University (SBU), the Materials Project at DOE's Lawrence Berkeley National Laboratory (Berkeley Lab), the University of California, Berkeley, and European collaborators have developed a new way to decipher the atomic-level structure of materials based on data gleaned from ground-up powder samples.
Southern small-leaved oak forests are the habitats with a higher level of spider endemism in the Iberian Peninsula, according to an article published in the journal Biodiversity and Conservation. The study analyses the factors that affect biodiversity patterns of spider communities in the national park network of Spain, and explains the role of the environmental factors in the distribution of the biodiversity of this faunistic group in the peninsular territory.
