A molecular robot is a next-generation biochemical machine that imitates the actions of microorganisms. It is made of biomaterials such as DNA, proteins, and lipids. Three prerequisites have been proposed for the construction of such a robot: sensors, intelligence, and actuators. This Mini review focuses on recent research on synthetic
A coronavirus is keeping the world in suspense. SARS-CoV-2 is highly infectious and can cause severe pneumonia with respiratory distress (COVID-19). Scientists are doing research in order to prevent the viruses from multiplying. A team from the University of Lübeck has now found a promising approach. Using the high-intensity X-ray
In cellular biology, the electron transport chain is one of the steps in the cell's processes that make energy from the food we eat. It is the third step of aerobic cellular respiration. Cellular respiration is the term for how your body's cells make energy from
All our activities — eating, walking, talking — are controlled by our brains, the center of the nervous system. The brain receives huge amounts of information from outside our body via our five senses (vision, sound, taste, touch, and smell), integrates this information, and orders our muscles to take action. How is
DNA is often thought of as the "software" of life. When talking about deoxyribonucleic acid -- DNA, the molecule that carries the genetic information of life -- scientists often make comparisons to computer systems, with DNA being an enormous "program" to be run by the body&
Microwaves (MW), electromagnetic waves with frequencies ranging from 300 MHz to 300 GHz, have been widely used in the telecommunications, agriculture, transportation, medical and military fields. The popularization of mobile phones, computers, household appliances and other electronic equipment has made learning, working and accessing entertainment much more convenient. With the
Why human layer 2/3 neurons? The human brain has evolved an extraordinarily thick cortex with layers 2 and 3 (L2/3 of 6) particularly important in cognitive function. These L2/3 human cortical neurons form dendritic trees, which the researchers explain “largely determine the repertoire of transformations of the
Technology isn’t what it used to be. 40 years ago, computers were strange machines locked away in the bowels of large organizations, tended to by an exclusive priesthood who could speak their strange languages. They were mostly used for mundane work, like scientific computation and back office functions in
Every major city has a central hub through which its citizens can access public transportation to get to their desired destination. In the case of the human body, the nervous system can be divided into the major road ways (nerves) that carry individuals (impulses) to and from the big city

A team of neuroscientists at Georgetown University Medical Center have found, in animal models, that they can "switch off" epileptic seizures. The findings, published online in Proceedings of the National Academy of Sciences (PNAS), provide the first evidence that while different types of seizures start in varied areas
neuronal computation
Neuroscientists reported December 12 in Cell, they may finally be able to reveal what circuits deep in the brain are up to, thanks in large part to a molecule that lights up brighter than ever before in response to subtle electrical changes that neurons use to perform their computations. Currently,
Aiva is an Artificial Intelligence (A.I.) capable of composing emotional soundtracks for films, video games, commercials and any type of entertainment content. She has been learning the art of music composition by reading through a large collection of music partitions, written by the greatest Composers (Mozart, Beethoven, Bach, ...) to
Spinal cord injury disrupts the connection between brain and body, causing devastating loss of physiological function to the wounded warfighter. In addition to paralysis, service members living with these injuries exhibit increased long-term morbidity due to factors such as respiratory and cardiovascular complications. Bridging the Gap Plus (BG+), a new

Cognitive computing re-defines BI and Information Technology. It is a combination of simplified analytical algorithms, natural language processing, machine learning, and massive computer processing power resulting in increased predictive analysis and pattern discovery. Machine Learning Machine Learning (ML) Is a discipline where a program or system can learn from existing
DNA barcoding provides a rapid, accurate, and standardised method for species-level identification using short DNA sequences. Such a standardised identification method is useful for mapping all the species on Earth, particularly when DNA sequencing technology is cheaply available. There are many nations in Asia with many biodiversity resources that need
A consortium of industry and science organisations is developing a software platform to enable a satellite-based communications layer to supplement for terrestrial 5G mobile communications and enable nationwide coverage in Germany. The space industry is changing as more and more private players are pushing their way into the state-dominated market
