Osmosis is fundamentally the process of water molecules moving through a semi-permeable membrane from a region of lower solute concentration to a region of higher solute concentration.

Researchers discovered that after previously being exposed to mustard oil, those with so-called Neanderthal variations in the sensory neuron-related gene SCN9A are more susceptible to pain from skin pricking. Three mutations in the SCN9A gene, referred to as M932L, V991L, and D1908G, have been found in sequenced Neanderthal genomes and there have been reports of increased pain sensitivity in people who possess all three variants. The precise sensory responses impacted by these variations were unknown, though, until this study.
Centrifugation is a technique used to separate cells, filter viral particles, precipitate DNA, and detect minute variations in molecular conformation.
Washington State University has developed a new technology for the development of cells using a bioreactor for cancer therapy. this technique develops cancer-detecting white blood cells (WBC) which supports immunotherapy.
Researchers at Washington State University have created a bioreactor the size of a minifridge that can produce T cells at 95% of their maximal development rate, which is around 30% quicker than what is possible with existing technology. They developed it using T cells from cattle. They expect it will function similarly on human cells.
A paternity test using DNA is the legitimate method to identify a person’s biological father. It is a widely accepted method by law for clearing paternity disputes. These tests can be done with any biological material containing DNA, but preferably blood tests and swab tests are generally used. Technically this method can also able to determine the father of an unborn baby.
Amplified fragment length polymorphism PCR is a PCR-based tool used in genetics research, DNA fingerprinting and in the practice of genetic engineering. In short, AFLP is an intermediate stage between RFLP and PCR.
Ian Wilmut, the lead for the team to create the world’s first cloned animal, Dolly the sheep, dies at the age of 79. His work at the Roslin Insitute, Edinburgh, laid the foundation for stem cell research.
The powerful analytical method, high-performance liquid chromatography (HPLC), is employed in many scientific disciplines, including chemistry, pharmacology, biochemistry, and environmental studies.
The basis of the randomly amplified polymorphic DNA (RAPD) technique is differential PCR amplification of genomic DNA. It uses short random oligonucleotide sequences (usually 10 bases long) to infer DNA polymorphisms caused by “rearrangements or deletions at or between oligonucleotide primer binding sites in the genome.”
Trisomy 21 another name for Down syndrome is a genetic disorder that impacts millions of people worldwide. It bears the name of British surgeon John Langdon Down, who initially identified the illness in 1866. An additional copy of chromosome 21 causes developmental and intellectual difficulties as well as distinctive talents […]
