Published Could future AI crave a favorite food?
(via sciencedaily.com) Original source Can artificial intelligence (AI) get hungry? Develop a taste for certain foods? Not yet, but a team of researchers is developing a novel electronic tongue that mimics how taste influences what we eat based on both needs and wants, providing a possible blueprint for AI that processes information more like a human being.
Published These robots helped explain how insects evolved two distinct strategies for flight
(via sciencedaily.com) Original source Robots helped achieve a major breakthrough in our understanding of how insect flight evolved. The study is a result of a six-year long collaboration between roboticists and biophysicists.
Published Graphene oxide reduces the toxicity of Alzheimer's proteins
(via sciencedaily.com) Original source A probable early driver of Alzheimer's disease is the accumulation of molecules called amyloid peptides. These cause cell death, and are commonly found in the brains of Alzheimer’s patients. Researchers have now shown that yeast cells that accumulate these misfolded amyloid peptides can recover after being treated with graphene oxide nanoflakes.
Published Human disease simulator lets scientists choose their own adventure
(via sciencedaily.com) Original source Scientists have developed a device smaller than a toddler's shoebox -- called Lattice --that can simulate any human disease in up to eight organs (cell cultures from a human organ) or test new drugs without ever entering -- or harming -- the body. It is a major advancement from current in vitro systems, which can only study two cell cultures simultaneously.
Published Electronic sensor the size of a single molecule a potential game-changer
(via sciencedaily.com) Original source Researchers have developed a molecular-sized, more efficient version of a widely used electronic sensor, in a breakthrough that could bring widespread benefits.
Published Bioengineering breakthrough increases DNA detection sensitivity by 100 times
(via sciencedaily.com) Original source Researchers have pushed forward the boundaries of biomedical engineering one hundredfold with a new method for DNA detection with unprecedented sensitivity.
Published Wearable sensor to monitor 'last line of defense' antibiotic
(via sciencedaily.com) Original source Researchers have combined earlier work on painless microneedles with nanoscale sensors to create a wearable sensor patch capable of continuously monitoring the levels of a ‘last line of defense’ antibiotic.
Published Metal-loving microbes could replace chemical processing of rare earths
(via sciencedaily.com) Original source Scientists have characterized the genome of a metal-loving bacteria with an affinity for rare earth elements. The research paves the way towards replacing the harsh chemical processing of these elements with a benign practice called biosorption.
Published Groundbreaking mathematical proof: New insights into typhoon dynamics unveiled
(via sciencedaily.com) Original source A research team has provided irrefutable proof that certain spherical vortices exist in a stable state.
Published Small but mighty new gene editor
(via sciencedaily.com) Original source A new CRISPR-based gene-editing tool has been developed which could lead to better treatments for patients with genetic disorders. The tool is an enzyme, AsCas12f, which has been modified to offer the same effectiveness but at one-third the size of the Cas9 enzyme commonly used for gene editing. The compact size means that more of it can be packed into carrier viruses and delivered into living cells, making it more efficient.
Published Making elbow room: Giant molecular rotors operate in solid crystal
(via sciencedaily.com) Original source Concave, umbrella-like metal complexes provide space to enable the largest molecular rotor operational in the solid-state.
Published Intense lasers shine new light on the electron dynamics of liquids
(via sciencedaily.com) Original source The behavior of electrons in liquids is crucial to understanding many chemical processes that occur in our world. Using advanced lasers that operate at the attosecond, a team of international researchers has revealed further insights into how electrons behave in liquids.
Published A deep look into the progression of Parkinson's Disease
(via sciencedaily.com) Original source Scientists have used cutting-edge imaging techniques to shed light on the progression of Parkinson's disease by studying how the main culprit, the protein alpha-synuclein, disrupts cellular metabolism.
Published An advance in cryo-EM could be a significant boon for research on potential cancer therapies
(via sciencedaily.com) Original source A technology called cryo-electron microscopy enables scientists to see the atomic structure of biological molecules in high resolution. But to date, it has been ineffective for imaging small molecules. A team of biochemists devised a solution that makes it possible to hold small protein molecules in place while they're being imaged, which will enable cryo-EM to produce much clearer images of such molecules. The advance is significant because small and medium-sized protein molecules are an area of focus in research on potential new drugs for cancer and other diseases.
Published Researchers dynamically tune friction in graphene
(via sciencedaily.com) Original source The friction on a graphene surface can be dynamically tuned using external electric fields, according to researchers.
Published Toxic formaldehyde's dual nature to be probed with new chemical tool
(via sciencedaily.com) Original source Newly developed ompounds aim to reveal the dual nature of formaldehyde, a chemical that is known to cause cancer but is also believed to play important roles in our biology.
Published Capturing CO2 with electricity: A microbial enzyme inspires electrochemistry
(via sciencedaily.com) Original source Humanity continuously emits greenhouse gases and thereby worsens global warming. Increasing research efforts go into developing strategies to convert these gases, such as carbon dioxide (CO2), into valuable products. CO2 accumulates dramatically over the years and is chemically very stable, thus challenging to transform. Yet, for billions of years, some microbes have actively captured CO2 using highly efficient enzymes. Scientists have now isolated one of these enzymes. When the enzyme was electronically branched on an electrode, they observed the conversion of CO2 to formate with perfect efficiency. This phenomenon will inspire new CO2-fixation systems because of its remarkable directionality and rates.
Published Accelerating sustainable semiconductors with 'multielement ink'
(via sciencedaily.com) Original source Scientists have demonstrated 'multielement ink' -- the first 'high-entropy' semiconductor that can be processed at low-temperature or room temperature. The new material could enable cost-effective and energy-efficient semiconductor manufacturing.
Published How a suction cup delivers medications to the bloodstream
(via sciencedaily.com) Original source A mini-suction cup allows for the painless administration of medications that previously could only be injected. It stretches the mucosal lining of the cheek and, in combination with a penetration-promoting agent, makes this barrier more permeable to medications. The researchers now want to bring their new delivery system to market.
Published Wearable patch wirelessly monitors estrogen in sweat
(via sciencedaily.com) Original source A new sensor may make it easier for women to monitor their estradiol, which plays a role in health and fertility.
