Published Human cells help researchers understand squid camouflage
(via sciencedaily.com) Squids and octopuses are masters of camouflage. But some aspects of how they become reversibly transparent are still 'unclear,' because researchers can't culture cephalopod skin cells in the lab. Now, researchers have replicated the tunable transparency of squid skin in mammalian cells, which are more easily cultured.
Published Meet the hybrid micro-robot: The tiny robot that is able to navigate in a physiological environment and capture targeted damaged cells
(via sciencedaily.com) Researchers have developed a hybrid micro-robot, the size of a single biological cell (about 10 microns across), that can be controlled and navigated using two different mechanisms -- electric and magnetic. The micro-robot is able to navigate between different cells in a biological sample, distinguish between different types of cells, identify whether they are healthy or dying, and then transport the desired cell for further study, such as genetic analysis.
Published Pathogen mapped: Evolution and potential treatments
(via sciencedaily.com) A parasite which has devastating impacts on agriculture and human health is the first pathogen to have its proteins located and mapped within its cells -- providing clues to their function and helping to identify potential drug targets.
Published More predictable renewable energy could lower costs
(via sciencedaily.com) Lower electricity costs for consumers and more reliable clean energy could be some of the benefits of a new study by researchers who have examined how predictable solar or wind energy generation is and the impact of it on profits in the electricity market.
Published AI 'brain' created from core materials for OLED TVs
(via sciencedaily.com) A research team develops semiconductor devices for high-performance AI operations by applying IGZO materials widely used in OLED displays.
Published Harnessing power of immune system may lessen reliance on antibiotics for infections like TB
(via sciencedaily.com) Researchers have found that the body's process of removing old and damaged cell parts, is also an essential part of tackling infections that take hold within our cells, like TB. If this natural process can be harnessed with new treatments, it could present an alternative to, or improve use of antibiotics, especially where bacteria have become resistant to existing drugs.
Published Researchers discover a way to fight the aging process and cancer development
(via sciencedaily.com) Damage in the human genome can be repaired. But this works better in germ cells, sperm and eggs, than in normal body cells. Responsible for this is the DREAM protein complex, which prevents the activation of all available repair mechanisms. A research team has now shown that normal body cells can also be repaired better once this complex has been deactivated. In the long run, the scientists hope to develop better therapies to prevent cancer and aging-associated diseases.
Published Without this, plants cannot respond to temperature
(via sciencedaily.com) Scientists have significantly advanced the race to control plant responses to temperature on a rapidly warming planet. Key to this breakthrough is miRNA, a molecule nearly 200,000 times smaller than the width of a human hair.
Published Visualizing spatial distribution of electric properties at microscales with liquid crystal droplets
(via sciencedaily.com) Existing sensor probes for microelectrical devices can measure only their average electric properties, providing no information on their spatial distribution. Liquid crystal droplets (LCDs) -- microscopic droplets of soft matter that respond to electric field -- are promising in this regard. Accordingly, researchers recently visualized the electric field and electrostatic energy distribution of microstructured electrodes by recording the motion of LCDs under an applied voltage, making for high detection accuracy and spatial resolution.
Published Optical switching at record speeds opens door for ultrafast, light-based electronics and computers
(via sciencedaily.com) Imagine a home computer operating 1 million times faster than the most expensive hardware on the market. Now, imagine that being the industry standard. Physicists hope to pave the way for that reality.
Published Global experts propose a path forward in generating clean power from waste energy
(via sciencedaily.com) Scientists have created a comprehensive 'roadmap' to guide global efforts to convert waste energy into clean power.
Published Robot caterpillar demonstrates new approach to locomotion for soft robotics
(via sciencedaily.com) Researchers have demonstrated a caterpillar-like soft robot that can move forward, backward and dip under narrow spaces. The caterpillar-bot's movement is driven by a novel pattern of silver nanowires that use heat to control the way the robot bends, allowing users to steer the robot in either direction.
Published Memory B cell marker predicts long-lived antibody response to flu vaccine
(via sciencedaily.com) Memory B cells play a critical role to provide long-term immunity after a vaccination or infection. Researchers have now described a distinct and novel subset of memory B cells that predict long-lived antibody responses to influenza vaccination in humans. These effector memory B cells appear to be poised for a rapid serum antibody response upon secondary challenge one year later.
Published New invention: The oxygen-ion battery
(via sciencedaily.com) An oxygen-ion-battery has been invented, based on ceramic materials. If it degrades, it can be regenerated, therefore it potentially has an extremely long lifespan. Also, it does not require any rare elements and it is incombustible. For large energy storage systems, this could be an optimal solution.
Published Cracking the concrete code
(via sciencedaily.com) New research introduces metamaterial concrete for the development of smart civil infrastructure systems. Researchers present a new concept for lightweight and mechanically-tunable concrete systems that have integrated energy harvesting and sensing functionality.
Published To ward off aging, stem cells must take out the trash
(via sciencedaily.com) Researchers find stem cells use a surprising system for discarding misfolded proteins. This unique pathway could be the key to maintaining long-term health and preventing age-related blood and immune disorders.
Published Synthesis gas and battery power from sunlight energy
(via sciencedaily.com) Plants use photosynthesis to harvest energy from sunlight. Now researchers have applied this principle as the basis for developing new sustainable processes which in the future may produce syngas (synthetic gas) for the large-scale chemical industry and be able to charge batteries.
Published 'Y-ball' compound yields quantum secrets
(via sciencedaily.com) Scientists investigating a compound called 'Y-ball' -- which belongs to a mysterious class of 'strange metals' viewed as centrally important to next-generation quantum materials -- have found new ways to probe and understand its behavior.
Published High-energy-density, long life-cycle rechargeable lithium metal batteries
(via sciencedaily.com) Research shows promise for developing high-energy-density rechargeable lithium-metal batteries and addressing the electrochemical oxidation instability of ether-based electrolytes.
