Cornell researchers who build nanoscale electronics have developed microsensors so tiny, they can fit 30,000 on one side of a penny. There's more to these tiny sensors than just their diminutive size: They are equipped with an integrated circuit, solar cells and light-emitting diodes (LEDs) that enable
Epigenetics is the study of biological mechanisms that will switch genes on and off, to be put as a simplified definition. What does that mean? Well, if you are new to this whole thing, we first need a quick crash course in biochemistry and genetics before learning exactly what is
A newly developed wireless biologging network (WBN) enables high-resolution tracking of small animals, according to a study published April 2 in the open-access journal PLOS Biology by Simon Ripperger of the Leibniz Institute for Evolution and Biodiversity Science, and colleagues. As noted by the authors, WBNs could close an important
An international group of researchers has set up a brain-machine interface between cultured nerve cells and electronic chips linked over the internet, which could lead to the development of AI implants for treating neurological disorders. As described in a study published in Nature Scientific Reports, the team set up a
The ability to efficiently visualize protein targets in cells is a fundamental goal in biological research. Recently, quantum dots (QDots) have emerged as a powerful class of fluorescent probes for labelling membrane proteins in living cells because of breakthrough advances in QDot surface chemistry and bio-functionalization strategies. This review discusses
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
