Published Leadership online: Charisma matters most in video communication
(via sciencedaily.com) Managers need to make a consistent impression in order to motivate and inspire people, and that applies even more to video communication than to other digital channels. Researchers investigated the influence that charismatic leadership tactics used in text, audio and video communication channels have on employee performance. They focused on mobile work and the gig economy, in which jobs are flexibly assigned to freelancers via online platforms.
Published A better way to quantify radiation damage in materials
(via sciencedaily.com) Researchers find much of the damage inside nuclear reactors is so small that it has eluded previous tests. Their new tool provides a way to directly measure this damage, potentially opening a path for the safe operation of nuclear power plants far beyond their present licensed lifetimes.
Published Suspended sediment reduced by rapid revegetation after Fukushima decontamination
(via sciencedaily.com) Researchers have found that soil decontamination efforts following the Fukushima nuclear accident resulted in constant, high levels of suspended river sediment downstream, but a rapid decrease in the amount of particulate radiocesium. Additionally, the rapid recovery of vegetation reduced the duration of unsustainable sediment effects. Future remediation projects should assess the natural restoration ability of local landscapes, and include appropriate revegetation measures to reduce the effects on downstream environments.
Published Listening to the people results in a more sustainable future energy system
(via sciencedaily.com) By taking into account the demographics and preferences of US racial groups, clarified through a nationally representative survey of 3,000 US residents, researchers have created a 'desirable' electricity generation mix for 2050 that includes 50% more energy from renewables than current projections. Combining such bottom-up input with top-down energy system goals set by policymakers could help meet both the needs and preferences of the population along with emission and climate goals.
Published Engineers develop stickers that can see inside the body
(via sciencedaily.com) Engineers designed an adhesive patch that produces ultrasound images of the body. The stamp-sized device sticks to skin and can provide continuous ultrasound imaging of internal organs for 48 hours.
Published Improving image sensors for machine vision
(via sciencedaily.com) Researchers highlight the latest nanostructured components integrated on image sensor chips that are most likely to make the biggest impact in multimodal imaging and detailed a promising approach to detect multiple-band spectra by fabricating an on-chip spectrometer. The developments could enable autonomous vehicles to see around corners instead of just a straight line, biomedical imaging to detect abnormalities at different tissue depths, and telescopes to see through interstellar dust.
Published Smaller, stronger magnets could improve devices that harness the fusion power of the sun and stars
(via sciencedaily.com) PPPL researchers have found a way to build powerful magnets smaller than before, aiding the design and construction of machines that could help the world harness the power of the sun to create electricity without producing greenhouse gases that contribute to climate change.
Published Chemists unlock secrets of molten salts
(via sciencedaily.com) Researchers have come up with a novel way to study the thermodynamic properties of molten salts, which are used in many nuclear and solar energy applications.
Published Flexible method for shaping laser beams extends depth-of-focus for OCT imaging
(via sciencedaily.com) Researchers have developed a new method for flexibly creating various needle-shaped laser beams. These long, narrow beams can be used to improve optical coherence tomography (OCT), a noninvasive and versatile imaging tool that is used for scientific research and various types of clinical diagnoses.
Published Go with the flow: New findings about moving electricity could improve fusion devices
(via sciencedaily.com) Researchers have found that updating a mathematical model to include a physical property known as resistivity could lead to the improved design of doughnut-shaped fusion facilities known as tokamaks.
Published Music-making and the flow of aerosols
(via sciencedaily.com) If simply breathing can spread the SARS-CoV-2 virus to others nearby, what about blowing into a tuba? Researchers used fluid mechanics to study the movement of aerosols generated by professional musicians.
Published Eco-friendly sound absorbers from seaweed
(via sciencedaily.com) From airplanes to apartments, most spaces are now designed with sound-absorbing materials that help dampen the droning, echoing and murmuring sounds of everyday life. But most of the acoustic materials that can cancel out human voices, traffic and music are made from plastic foams that aren't easily recycled or degraded. Now, researchers have created a biodegradable seaweed-derived film that effectively absorbs sounds in this range.
Published Scientists propose solution to a long-puzzling fusion problem
(via sciencedaily.com) Researchers demonstrate explanation of paradox that could apply to all spherical tokamaks, cost-effective candidates to model a fusion pilot plant.
Published X-rays help researchers piece together treasured cellular gateway
(via sciencedaily.com) After almost two decades of synchrotron experiments, scientists have captured a clear picture of a cell's nuclear pores, which are the doors and windows through which critical material in your body flows in and out of the cell's nucleus. These findings could lead to new treatments of certain cancers, autoimmune diseases and heart conditions.
Published Scientists invent 'quantum flute' that can make particles of light move together
(via sciencedaily.com) Physicists have invented a 'quantum flute' that, like the Pied Piper, can coerce particles of light to move together in a way that's never been seen before.
Published Hearing better with skin than ears
(via sciencedaily.com) A research team develops a sound-sensing skin-attachable acoustic sensor. The new sensor decreased in size and increased in flexibility and is applicable as auditory electronic skin.
Published Laser creates a miniature magnetosphere
(via sciencedaily.com) A research team realized magnetic reconnection driven by electron dynamics in laser-produced plasmas and measured the pure electron outflows. Their findings will be applied not only to space and astrophysical plasmas, but also to magnetic propulsion and fusion plasmas.
Published Optical microphone sees sound like never before
(via sciencedaily.com) A camera system can see sound vibrations with such precision and detail that it can reconstruct the music of a single instrument in a band or orchestra. Even the most high-powered and directed microphones can't eliminate nearby sounds, ambient noise and the effect of acoustics when they capture audio. The novel system uses two cameras and a laser to sense high-speed, low-amplitude surface vibrations. These vibrations can be used to reconstruct sound, capturing isolated audio without inference or a microphone.
Published High-intensity focused ultrasound (HIFU) can control prostate cancer with fewer side effects
(via sciencedaily.com) High-intensity focused ultrasound (HIFU) can help some men with prostate cancer avoid surgery or radiation.
Published Moth wing-inspired sound absorbing wallpaper in sight after breakthrough
(via sciencedaily.com) Experts at the University of Bristol have discovered that the scales on moth wings act as excellent sound absorbers even when placed on an artificial surface.
