What is epigenetics?

Epigenetics is the study of changes that do not involve alterations in the DNA sequence. Epigenetic changes are modifications to DNA that regulate whether genes are turned on or off. These modifications are attached to DNA and do not change the sequence of DNA building blocks. Within the complete set of DNA in a cell (genome), all of the modifications that regulate the activity (expression) of the genes is known as the epigenome. Epigenetics most often involves changes that affect gene activity and expression, but the term can also be used to describe any heritable phenotypic change.

Epigenetics in bacteria

Epigenetics have fundamentals importance in eukaryotes, especially metazoan. Eukaryotes use epigenetics mechanism to regulate gene expressions which bacteria rarely do. In Alphaproteobacteria, methylation of adenine regulates the cell cycle and couple gene transcription to DNA replication.

Medicines

Epigenetics has many and varied potential medical applications. It has the potential to explain mechanisms of aging, human development, and the origins of cancer, heart disease, mental illness, as well as several other conditions. The use of beta-lactam antibiotics can alter glutamate receptor activity and the action of cyclosporine on multiple transcription factors. Additionally, lithium can impact autophagy of aberrant proteins, and opioid drugs via chronic use can increase the expression of genes associated with addictive phenotypes.

Pseudoscience

Due to epigenetics being in the early stages of development as a science and the sensationalism surrounding it in the public media, David Gorski and geneticist Adam Rutherford advised caution against proliferation of false and pseudoscientific conclusions by new age authors who make unfounded suggestions that a person's genes and health can be manipulated by mind control. Misuse of the scientific term by quack authors has produced misinformation among the general public.

NVIDIA Tesla V100 - First Tensor Core GPU

8x NVIDIA Tesla V100 32GB Server As we all know NVIDIA processor are so famous now a days. It give a perfect gaming performance and people used it worldwide. The thing is that it is not only use in personal computer but also at data center, where so many super computer are present for providing services. So, NVIDIA Tesla V100 is a first tensor core GPU. It is especially built to focus on AI, High Performance Computing ( HPC ) and graphics. It is powered by NVIDIA Volta Architecture. It comes with configuration 16 and 32GB and have a performance up to 100 CPUs in single GPU. A single server node with V100 GPUs can replace 60 CPUs nodes. DATA CENTER GPUs Image © NVIDIA NVIDIA V100 for NVLINK Performance with NVIDIA GPU Boost for double precision is 7.8 teraflops and single precision is 15.7 teraflops. Deep learning performance boost is 125 teraflops. Interconnect bandwidth with bidirectional is 300 GB/s. It have memory capacity of 32/16 GB HBM2 with bandwidth 900GB/s. I...

The Amazing Vantablack Material...!!

Vantablack is a material developed by Surrey NanoSystems in the United Kingdom and is one of the darkest substances known, absorbing up to 99.96% of visible light (at 663 nm if the light is perpendicular to the material).The name is a compound of the acronym VANTA (vertically aligned carbon nanotube arrays) and the color black. Vantablack is not actually a color pigment or a paint, but a coating of carbon nanotubes. These have the property of absorbing incident light almost completely. Against a deep black background, objects coated in Vantablack material seem to disappear, as the perception of spatial depth is lost. This is because the human eye perceives shapes coated in Vantablack to be two-dimensional. IUPAC Name is Activated carbon high density skeleton. Other names are Multiwalled carbon nanotube (MWCNT), Vantablack S-VIS and Vantablack S-IR. It is insoluble in water. When light strikes Vantablack, instead of bouncing off, it becomes trapped and is continually deflected amo...

SCADA Network

So welcome to my blog. In this post I am gonna write about SCADA network. This actually come to my mind because of web show named Mr. Robot. The show is awesome if you love hacking believe me you will enjoy the series. So basically the SCADA ( Supervisory Control and Data Acquisition ) is a control system architecture comprising computers, networked data communications and graphical user interface for high level process supervisory management, while also comprising other peripheral devices like programmable logic controllers and discrete proportional-integral-derivative controllers to interface with process plant or machinery. SCADA networks used for monitoring and controlling the industry like telecommunication, water plant, etc. It is one of the most commonly used industrial control system, in spite of concerns about SCADA system being vulnerable to cyberattack. This network is used for gathering info about the system, transferring that info to central site, alerting...
