Unexpected 'Black Swan' defect discovered in soft matter Posted: 19 May 2021 01:36 PM PDT Scientists have revealed a single microscopic defect called a 'twin' in a soft-block copolymer using an advanced electron microscopy technique. This defect may be exploited in the future to create materials with novel acoustic and photonic properties. |
New framework incorporating renewables and flexible carbon capture Posted: 18 May 2021 05:54 PM PDT As the global energy demand continues to grow along with atmospheric levels of carbon dioxide (CO2), there has been a major push to adopt more sustainable and more carbon-neutral energy sources. Solar/wind power and CO2 capture - the process of capturing waste CO2 so it is not introduced into the atmosphere - are two promising pathways for decarbonization, but both have significant drawbacks. |
Embryo cryopreservation minimizes cryoinjuries, offers hope for would-be parents Posted: 18 May 2021 08:48 AM PDT Not all embryo transfers succeed, which gives rise to the practice of freezing extra embryos from an IVF cycle for future transfers. This allows those with at-risk fertility, due to age or treatments such as chemotherapy, to delay their transfer. Researchers introduce a standalone microfluidics system to automate the process of embryo vitrification of replacing water with cryoprotectants, which exposes embryos to a slow and constantly increasing concentration of cryoprotectants. |
Wake steering potentially boosts energy production at US wind plants Posted: 18 May 2021 08:47 AM PDT Wake steering is a strategy employed at wind power plants involving misaligning upstream turbines with the wind direction to deflect wakes away from downstream turbines, which consequently increases the net production of wind power at a plant. Researchers illustrate how wake steering can increase energy production for a large sampling of commercial land-based U.S. wind power plants. Several were ideal candidates. |
Rechargeable cement-based batteries Posted: 18 May 2021 08:42 AM PDT Imagine an entire twenty storey concrete building which can store energy like a giant battery. Thanks to unique research, such a vision could someday be a reality. Researchers recently published an article outlining a new concept for rechargeable batteries - made of cement. |
Electric cars: Special dyes could prevent unnecessary motor replacements Posted: 18 May 2021 08:42 AM PDT In the near future dyes in electric motors might indicate when cable insulation is becoming brittle and the motor needs replacing. Scientists have developed a new process that enables the dyes to be directly integrated into the insulation. By changing color, they reveal how much the insulating resin layer around the copper wires in the motor has degraded. |
When one become two: Separating DNA for more accurate nanopore analysis Posted: 18 May 2021 08:41 AM PDT A new software tool will help bioinformaticians improve the quality and accuracy of their biological data, and avoid mis-assemblies. The fast, lightweight, user-friendly tool visualizes genome assemblies and gene alignments from the latest next generation sequencing technologies. |
Mathematical model predicts effect of bacterial mutations on antibiotic success Posted: 18 May 2021 08:41 AM PDT Scientists have developed a mathematical model that predicts how the number and effects of bacterial mutations leading to drug resistance will influence the success of antibiotic treatments. |
Scientists map gene changes underlying brain and cognitive decline in aging Posted: 18 May 2021 08:41 AM PDT Alzheimer's disease shares some key similarities with healthy aging, according to a new mathematical model. |
