Published Gut microbiome plays key role in response to CAR-T cell cancer immunotherapy
(via sciencedaily.com)
Original source 
Scientists have found that the gut microbiome may modulate the efficacy of CAR-T cellular immunotherpy CAR-T cells in patients with B cell lymphomas. Individualized microbiome information retreaved from patients' gut microbiomes prior to initiation of CAR T therapy could accurately predict their subsequent responsiveness to therapy, but only in the condition that these patients were not pre-treated with broad spectrum antibiotics.
Published Are piezoelectrics good for generating electricity? Perhaps, but we must decide how to evaluate them
(via sciencedaily.com) 
A 'best practice' protocol for researchers developing piezoelectric materials has been developed by scientists. The protocol was developed by an international team led by physicists in response to findings that experimental reports lack consistency. The researchers made the shocking discovery that nine out of 10 scientific papers miss experimental information that is crucial to ensure the reproducibility of the reported work.

Physicists are learning more about the bizarre behavior of 'strange metals,' which operate outside the normal rules of electricity.
Published Electrocatalysis under the atomic force microscope
(via sciencedaily.com) 
A further development in atomic force microscopy now makes it possible to simultaneously image the height profile of nanometer-fine structures as well as the electric current and the frictional force at solid-liquid interfaces. A team has succeeded in analyzing electrocatalytically active materials and gaining insights that will help optimize catalysts. The method is also potentially suitable for studying processes on battery electrodes, in photocatalysis or on active biomaterials.
Published New kind of transistor could shrink communications devices on smartphones
(via sciencedaily.com) 
One month after announcing a ferroelectric semiconductor at the nanoscale thinness required for modern computing components, a team has now demonstrated a reconfigurable transistor using that material. Their work paves the way for single amplifiers that can do the work of multiple conventional amplifiers, among other possibilities.
Published New 'camera' with shutter speed of 1 trillionth of a second sees through dynamic disorder of atoms
(via sciencedaily.com) 
Researchers have developed a new 'camera' that sees the local disorder in materials. Its key feature is a variable shutter speed: because the disordered atomic clusters are moving, when the team used a slow shutter, the dynamic disorder blurred out, but when they used a fast shutter, they could see it. The method uses neutrons to measure atomic positions with a shutter speed of around one picosecond, a trillion times faster than normal camera shutters.
Published Electric vehicle batteries could get big boost with new polymer coating
(via sciencedaily.com) 
Scientists have developed a polymer coating that could enable longer lasting, more powerful lithium-ion batteries for electric vehicles. The advance opens up a new approach to developing EV batteries that are more affordable and easy to manufacture.
Published Controlling electric double layer dynamics for next generation all-solid-state batteries
(via sciencedaily.com) 
Development of all-solid-state batteries is crucial to achieve carbon neutrality. However, their high surface resistance causes these batteries to have low output, limiting their applications. To this end, researchers have employed a novel technique to investigate and modulate electric double layer dynamics at the solid/solid electrolyte interface. The researchers demonstrate unprecedented control of response speed by over two orders of magnitude, a major steppingstone towards realization of commercial all-solid-state batteries.

Published Heterostructures support predictions of counterpropagating charged edge modes at the v=2/3 fractional quantum Hall state
(via sciencedaily.com)
Original source 
Researchers have tested models of edge conduction with a device built on top of the semiconductor heterostructure which consists of gold gates that come close together. Voltage is applied on the gates to direct the edge states through the middle of the point contact, where they are close enough that quantum tunneling can occur between the edge states on opposite sides the sample. Changes in the electrical current flowing through the device are used to test the theorists' predictions.
