| A faster, easier way to build diamond Posted: 25 Feb 2020 01:42 PM PST With the right amount of pressure and surprisingly little heat, a substance found in fossil fuels can transform into pure diamond. |
| Instrument may enable mail-in testing to detect heavy metals in water Posted: 25 Feb 2020 12:43 PM PST Researchers have developed an approach called SEPSTAT, for solid-phase extraction, preservation, storage, transportation, and analysis of trace contaminants. The method is based on a small, user-friendly device the team developed, which absorbs trace contaminants in water and preserves them in a dry state so the samples can be easily dropped in the mail and shipped to a laboratory for further analysis. |
| The do's and don'ts of monitoring many wildlife species at once Posted: 25 Feb 2020 12:43 PM PST A new analysis of 92 studies from 27 countries conducted by ecologists suggests that many recent multi-species studies of wildlife communities often incorrectly use the analytical tools and methods available. Technology such as trail cameras and drones have 'revolutionized wildlife monitoring studies' in recent years, says organismic and evolutionary biologists 'but if not properly used in well-designed research, they will compromise the reliability of the results obtained.' |
| From China to the South Pole: Joining forces to solve the neutrino mass puzzle Posted: 25 Feb 2020 09:29 AM PST A new study indicates that the next generation of neutrino experiments may well find the answer to one of the most pressing issues in neutrino physics. |
| Simple self-charging battery offers power solutions for devices Posted: 25 Feb 2020 08:44 AM PST A new type of battery combines negative capacitance and negative resistance within the same cell, allowing the cell to self-charge without losing energy, which has important implications for long-term storage and improved output power for batteries. Researchers report making their very simple battery with two different metals, as electrodes and a lithium or sodium glass electrolyte between them. |
| Lab-free infection test could eliminate guesswork for doctors Posted: 25 Feb 2020 08:44 AM PST A new infection test, made up of sheets of paper patterned by lasers, has been developed by researchers to allow diagnosis at the point of care -- helping doctors give patients the right treatment, faster. |
| Stimulating resonance with two very different forces Posted: 25 Feb 2020 08:44 AM PST In some specialized oscillators, two driving forces with significantly different frequencies can work together to make the whole system resonate. |
| Lights, camera, action... the super-fast world of droplet dynamics Posted: 25 Feb 2020 08:36 AM PST Cameras shooting up to 25,000 frames a second have been used to capture the moment two droplets of liquid come together and mix -- and it is opening up research into new applications for 3D printing. |
| Synthesizing a superatom: Opening doors to their use as substitutes for elemental atoms Posted: 25 Feb 2020 07:50 AM PST Scientists have demonstrated how superatoms of a desired valency, stability, and volume can be synthesized in a solution medium by altering the number of atoms in a cluster structure. This is an important step in realizing the practical application of superatom clusters as substitutes for elements in chemical reactions. |
| Posted: 25 Feb 2020 07:49 AM PST Using biomass and microbes to synthesize useful chemical compounds is an environmentally friendly alternative to petrochemical production, however it is difficult to produce sufficient amounts. A team has succeeded in improving the yield of the target chemical muconic acid by developing a new strategy to metabolically engineer the bacteria used in bioproduction, so that it would utilize different kinds of sugar absorbed from the biomass for separate aims. |
| Exceptional catapulting jump mechanism in a tiny beetle could be applied in robotic limbs Posted: 25 Feb 2020 07:49 AM PST The fascinating and highly efficient jumping mechanism in flea beetles has been described. Despite having been known since 1929, the explosive jump has not been fully understood. |
| What to expect when you're expecting electric transportation Posted: 25 Feb 2020 07:13 AM PST While electric vehicles alone may not reduce carbon emissions, a new study reveals that when electric vehicles are powered with renewable energy and coupled with carbon policy strategies, they can help combat climate change without sacrificing economic growth. |
| Turbomachine expander offers efficient, safe strategy for heating, cooling Posted: 25 Feb 2020 04:51 AM PST Researchers developed a device to decrease energy consumption of the vapor-compression heat pump cycle, which is commonly used in homes, businesses and vehicles for cooling and heating. The team created a novel turbomachine expander that helps harvest previously wasted energy used in the process of moving the air from high to low pressure. The device can be used as a control agent within an existing heat pump. |
| Best method to teach children augmented reality Posted: 25 Feb 2020 04:51 AM PST Researchers have identified the best approach to help children operate augmented reality (AR). According to computer science experts, a major barrier into wider adoption of the technology for experiential learning is based on AR designs geared toward adults that rely on voice or gesture commands. By conducting in-classroom testing among elementary school students, researchers uncovered that AR programs are best delivered using controller commands, followed by programs that communicate with age-specific language. |
| Noninvasive, self-adhesive sensor predicted worsening heart failure in veterans Posted: 25 Feb 2020 04:51 AM PST A removable, noninvasive, self-adhesive sensor successfully predicted worsening heart failure and the need for hospitalization in veterans several days before hospitalization occurred. The researchers used machine learning to analyze the data provided remotely by the sensor to detect if, and when, a patient's heart failure was worsening. |
| Neural cells speed up function in 3D bioprinted skeletal muscle constructs Posted: 24 Feb 2020 03:35 PM PST Scientists improve on 3D bioprinting research by investigating the effects of neural cell integration into bioprinted muscle constructs to accelerate functional muscle regeneration. |
| An 'exceptionally stable' single-atom catalyst Posted: 24 Feb 2020 08:13 AM PST Scientists have shown that single platinum atoms trapped in C12A7 crystals act as a stable and effective catalyst for the hydrogenation of nitroarenes, an essential process in the production of many kinds of fine chemicals. Their approach could become a versatile route for developing other single-atom catalysts for wide-ranging industrial applications. |
