Successful trials of titanium-copper alloys for 3D printing could kickstart a new range of high-performance alloys for medical device, defence and aerospace applications.
Current titanium alloys used in additive manufacturing often cool and bond together in column-shaped crystals during the 3D printing process, making them prone to cracking or distortion.
And unlike aluminium or other commonly used metals, there is no commercial grain refiner for titanium that manufacturers can use to effectively refine the microstructure to avoid these issues.
An international team of scientists led by the University of Arizona used the latest technology in remote sensing to measure plant biodiversity from the Amazon basin to the Andes Mountains in Peru to better understand how tropical forests will respond to climate change.
After a global genetic comparison, a team of international scientists has discovered that Asia has at least ten ancestral lineages, whereas northern Europe has a single ancestral lineage.
In their first study reported in Nature this week, the GenomeAsia 100K consortium analysed the genomes of 1,739 people, which represents the widest coverage of genetic diversity in Asia to date.
It's hard to find a place in the U.S. that isn't impacted by wildfires and smoke.
Dry landscapes, warmer temperatures and more development near forested areas all contribute to massive wildfires across North America each year. Smoke and haze from these fires can travel hundreds of miles from their source, affecting the health and wellbeing of communities across the U.S.
Entropy, a measure of the molecular disorder or randomness of a system, is critical to understanding a system's physical composition. In complex physical systems, the interaction of internal elements is unavoidable, rendering entropy calculation a computationally demanding, and often impractical, task. The tendency of a properly folded protein to unravel, for example, can be predicted using entropy calculations.
Now, a new Tel Aviv University study proposes a radically simple and efficient way of calculating entropy -- and it probably exists on your own computer.
NASA-NOAA's Suomi NPP satellite passed over the South China Sea and provided forecasters with a visible image of Tropical Storm Kammuri on Dec. 4.
NASA's OSIRIS-REx mission is just days away from selecting the site where the spacecraft will snag a sample from asteroid Bennu. After a lengthy and challenging process, the team is finally ready to down-select from the four candidate sites to a primary and backup site.
OSIRIS-REx is NASA's first asteroid sample return mission, so this decision of a sample collection site is key for asteroid operations and mission success.
NASA's Aqua satellite found some powerful storms in Tropical Storm 06A as it moved through the Arabian Sea toward Somalia.
NASA's Aqua satellite used infrared light to analyze the strength of storms in 06A and found it was maintaining strength. Infrared data provides temperature information, and the strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures.
WASHINGTON -- Early returns from the U.S. Naval Research Laboratory's camera on NASA's latest mission to study the Sun's corona revealed on Dec. 4 a star more complex than ever imagined.
NRL's Wide-field Imager for Parker Solar Probe, or WISPR, the only imaging instrument aboard the NASA Parker Solar Probe mission, is now 84 percent of the way to the Sun.
If one wants to calculate the environmental impact of purchasing a product or services, they must consider the role of the capital assets that went into their production -- machinery, factories, IT, vehicles, and roads -- and the energy and materials required to create those assets. For instance, any assessment of the environmental "footprint" of renting a home should include the materials and processes that went into its construction.
India can sustainably enhance its food supply if its farmers plant less rice and more nutritious and environmentally-friendly crops, including finger millet, pearl millet, and sorghum, according to a new study from the Data Science Institute at Columbia University.
It has long been suggested that a cell protease could take part in enterovirus infection. However, the identity of such proteases have remained unknown. The work performed in the University of Jyväskylä shows, for the first time, that host cell calpain proteases can process enterovirus polyprotein in vitro. The research was published in Viruses scientific journal in November 2019.
Enteroviruses are the most common viruses infecting humans. Although most of the diseases that enteroviruses cause are symptomless or mild, enteroviruses can also cause more severe diseases.
Understanding how microwave absorption changes the transport properties of diffusive Josephson junctions is at the forefront of interest in the quantum transport community. It is especially relevant for the current efforts to address the current-phase relation in topological Josephson junctions and more generally the microwave transport in quantum devices.
As the planet warms due to excess carbon dioxide in the atmosphere, a solution for drawing down that carbon - or at least a major part of it - lies silently below us.
SMU Office of Research & Tech Transfer - When considering an organisation's long-term survival, existential threats that come to mind include external competition or technological disruption. But a potential threat lurks within the firm itself - organisational misconduct among employees can destroy billions of dollars of market value and result in lasting reputational damage.
