Nano drops a million times smaller than a teardrop explodes 19th century theory Posted: 12 Feb 2019 09:00 AM PST Droplets emanating from a molecular 'nano-tap' would behave very differently from those from a household tap 1 million times larger -- researchers have found. This is potentially crucial step for a number of emerging nano technologies, e.g., manufacture of nano-sized drug particles, lab-on-chip devices for in situ diagnostics, and 3D printers capable of nanoscale resolution. |

Walking simulation games signal a new literary genre Posted: 12 Feb 2019 07:47 AM PST Walking simulation games signal a new literary genre Research has revealed that walking simulations are blurring the boundaries of different art forms to create a new literary genre. Walking simulations -- video games where there are no winners and no one is shot at or killed -- have become increasingly popular in the last few years. |
Improving geothermal HVAC systems with mathematics Posted: 12 Feb 2019 07:47 AM PST Sustainable heating, ventilation, and air conditioning systems, such as those that harness low-enthalpy geothermal energy, are needed to reduce collective energy use and mitigate the continued effects of a warming climate. Researchers use asymptotic expansion techniques to study the harmonic thermal response of vertical geothermal boreholes in such systems to sub-annual harmonic excitations. |

Selfies to self-diagnosis: Algorithm 'amps up' smartphones to diagnose disease Posted: 12 Feb 2019 06:26 AM PST Smartphones aren't just for selfies anymore. A novel cell phone imaging algorithm can now analyze assays typically evaluated via spectroscopy, a powerful device used in scientific research. Researchers analyzed more than 10,000 images and found that their method consistently outperformed existing algorithms under a wide range of operating field conditions. This technique reduces the need for bulky equipment and increases the precision of quantitative results. |
Simple and low-cost crack-healing of ceramic-based composites Posted: 12 Feb 2019 06:26 AM PST A team of researchers has demonstrated that cracks induced in composites consisting of alumina ceramics and titanium could be healed at room temperature, a world-first. This ceramic healing method permits crack-healing even in a state in which a device is mounted on a ceramic package at a low cost and without using complicated heat treatment processes that require significant amounts of energy. |

The physical forces of cells in action Posted: 12 Feb 2019 05:15 AM PST The detection of physical forces is one of the most complex challenges facing science. Considered to play a decisive role in many biological processes, the chemical tools to visualize the physical forces in action do not exist. But today, researchers have developed probes inspired by lobster cooking, they enable to enter into cells. For the first time, physical forces can be imaged live inside the cells. |

Engineered miniature kidneys come of age Posted: 11 Feb 2019 03:28 PM PST A research team has now removed a major barrier for the use of kidney organoids as a tool to model kidney diseases, test drug toxicities and eventually for the creation of organ replacements, the lack of a pervasive blood vessel system (vasculature). The team solved this problem with a powerful new approach that exposes stem cell-derived kidney organoids to fluidic shear stress and thus enables them to vascularize and mature further than they could before. |
