Hydrologic simulation models that inform policy decisions are difficult to interpret Posted: 11 Oct 2019 01:53 PM PDT Hydrologic models that simulate and predict water flow are used to estimate how natural systems respond to different scenarios such as changes in climate, land use, and soil management. The output from these models can inform policy and regulatory decisions regarding water and land management practices. Numerical models have become increasingly easy to employ with advances in computer technology and software with graphical user interface (GUI). While these technologies make the models more accessible, problems can arise if they are used by inexperienced modelers. |
Contextual engineering improves success of projects in non-industrial societies Posted: 11 Oct 2019 01:53 PM PDT Humanitarian engineering projects often focus on bringing western technologies to non-industrialized societies. But environmental and cultural factors in these locations may be very different from conditions in the West, and the projects may not meet client needs if engineers do not fully understand the context in which they are operating. |
Black holes stunt growth of dwarf galaxies Posted: 11 Oct 2019 01:53 PM PDT Astronomers have discovered that powerful winds driven by supermassive black holes in the centers of dwarf galaxies have a significant impact on the evolution of these galaxies by suppressing star formation. |
Nanoscale manipulation of light leads to exciting new advancement Posted: 11 Oct 2019 12:53 PM PDT Controlling the interactions between light and matter has been a long-standing ambition for scientists seeking to develop and advance numerous technologies that are fundamental to society. With the boom of nanotechnology in recent years, the nanoscale manipulation of light has become both, a promising pathway to continue this advancement, as well as a unique challenge due to new behaviors that appear when the dimensions of structures become comparable to the wavelength of light. |
'Electroadhesive' stamp picks up and puts down microscopic structures Posted: 11 Oct 2019 11:46 AM PDT New technique could enable assembly of circuit boards and displays with more minute components. |
New soft actuators could make soft robots less bulky Posted: 11 Oct 2019 11:20 AM PDT Engineers have developed a way to build soft robots that are compact, portable and multifunctional. The advance was made possible by creating soft, tubular actuators whose movements are electrically controlled, making them easy to integrate with small electronic components. As a proof of concept, engineers used the new actuators to build an untethered, battery-powered, walking soft robot and a soft gripper. |
Fast-acting German insecticide lost in the aftermath of WWII Posted: 11 Oct 2019 10:19 AM PDT A new study explores the chemistry as well as the complicated and alarming history of DFDT, a fast-acting insecticide. |
Six degrees of nuclear separation Posted: 11 Oct 2019 10:19 AM PDT For the first time, scientists have printed 3D parts that pave the way to recycling up to 97 percent of the waste produced by nuclear reactors. |
New test diagnoses Lyme disease within 15 minutes Posted: 11 Oct 2019 08:22 AM PDT Current testing for Lyme disease, called the standard 2-tiered approach or the STT, involves running two complex assays (ELISA and western blot) to detect antibodies against the bacterium, and requires experienced personnel in a lab, and a few hours to carry out and interpret. Biomedical engineers have developed a rapid microfluidic test that can detect Lyme disease with similar performance as the STT in a much shorter time -- 15 minutes. |
New material captures carbon dioxide and converts it into useful chemicals Posted: 11 Oct 2019 08:22 AM PDT The captured CO2 can be converted into useful organic materials. |
Physics: DNA-PAINT super-resolution microscopy at speed Posted: 11 Oct 2019 06:59 AM PDT Recent advances in fluorescence microscopy allow researchers to study biological processes below the classical diffraction limit of light. Researchers have now developed DNA-PAINT, a variant of these so-called super-resolution approaches. |
Liquid metals the secret ingredients to clean up environment Posted: 11 Oct 2019 06:59 AM PDT Liquid metal catalysts show great promise for capturing carbon and cleaning up pollutants, requiring so little energy they can even be created in the kitchen. |
Physics: An ultrafast glimpse of the photochemistry of the atmosphere Posted: 11 Oct 2019 06:59 AM PDT Researchers have explored the initial consequences of the interaction of light with molecules on the surface of nanoscopic aerosols. |
Powerful new genomics method can be used to reveal the causes of rare genetic diseases Posted: 11 Oct 2019 06:59 AM PDT The technique makes use of the fact that people inherit two copies or ''alleles'' of virtually every gene, one from the mother and one from the father. The new method compares activity levels of maternal and paternal alleles across the genome and detects when the activity of an allele lies far enough outside the normal range to be a plausible cause of disease. |
Physicists look to navigational 'rhumb lines' to study polymer's unique spindle structure Posted: 11 Oct 2019 04:47 AM PDT A new study describes how spheres can be transformed into twisted spindles thanks to insights from 16th century navigational tools. Researchers show how polymers can contract into spiral structures, known as loxodromes, that have complex patterning ten times smaller than the width of a human hair. |
Controlling superconducting regions within an exotic metal Posted: 11 Oct 2019 04:47 AM PDT Researchers have created a metallic microdevice in which they can define and tune patterns of superconductivity. Their discovery holds great promise for quantum technologies of the future. |
Radiation detector with the lowest noise in the world boosts quantum work Posted: 11 Oct 2019 04:47 AM PDT The nanoscale radiation detector is a hundred times faster than its predecessors, and can function without interruption. |
Combination of techniques could improve security for IoT devices Posted: 10 Oct 2019 01:48 PM PDT A multi-pronged data analysis approach that can strengthen the security of Internet of Things (IoT) devices -- such as smart TVs, home video cameras and baby monitors -- against current risks and threats has been created. |
