First Human Treated With CRISPR Gene-Edited Cells In China, Report Says
For the first time, a cancer patient is being treated with cells altered using a gene editing technique called CRISPR-Cas9.
CRISPR: Gene Editing Is Just The Beginning
The real power of the biological tool lies in exploring how genomes work. Molecular biologists are riding a wave of new technologies made possible by CRISPR.
Scientists Identify New Drivers Of Rare Cancer Type
Cancer researchers in Würzburg, in cooperation with the international Cancer Genome Atlas Research Network, have identified new genetic drivers of adrenal cancer. Würzburg was the center of coordinati...
Could The Food We Eat Affect Our Genes?| University Of Cambridge
The behaviour of our cells is determined by a combination of the activity of its genes and the chemical reactions needed to maintain the cells, known as metabolism. Metabolism works in two directions:...
Discovery Shows How Herpes Simplex Virus Reactivates In Neurons To Trigger Disease
About 90 percent of us live with HSV inside brain cells. Under stress, the virus leaves neurons and can cause cold sores, recurrent eye infection, and in rare cases encephalitis. For the first time, ...
First Look At How Astrocytes Function In Humans
Pretty much everything happening in the brain would fail without astrocytes. These star-shaped glia cells are known to have a critical role in synapse creation, nervous tissue repair, and the formatio...
Man's Weight 'Affects Sperm Cells'
A man's weight affects the information passed on through his sperm and could leave his children predisposed to obesity, research suggests. The sperm cells of lean and obese men possess different epige...
Gene On-Off Switch Works Like Backpack Strap
A research team based in Houston's Texas Medical Center has found that loop-forming proteins inside the human chromosome appear to work like the sliding plastic adjusters on a grade-schooler's backpac...
Stressed Dads Affect Offspring Brain Development Through Sperm MicroRNA
More and more, scientists have realized that DNA is not the only way that a parent can pass on traits to their offspring. Events experienced by a parent over a lifetime can also have an impact. Now Un...
Smoking And Heavy Alcohol Use Are Associated With Epigenetic Signs Of Aging
Using data from the publicly available Gene Expression Omnibus, Robert A. Philibert, MD, PhD and colleagues at the University of Iow8a and other institutions analyzed patterns of DNA methylation, a mo...
Discovery Of How Environmental Memories May Be Transmitted From A Father To His Grandchildren
If you have diabetes, or cancer or even heart problems, maybe you should blame it on your dad’s behaviour or environment. Or even your grandfather’s. That’s because, in recent years, scientists have s...
Researchers Discover Evidence That Lead Exposure In Mothers Can Affect Future Generation
A team of researchers at Wayne State University have discovered that mothers with high levels of lead in their blood not only affect the fetal cells of their unborn children, but also their grandchild...
Study: Alzheimer’s pathology might be transmittable via medical procedures
Researchers say “seeds” of Alzheimer’s-causing protein may have been carried by tissue extracts or improperly sterilized surgical instruments...
New Findings Shed Light On Fundamental Process Of DNA Repair
Inside the trillions of cells that make up the human body, things are rarely silent. Molecules are constantly being made, moved, and modified — and during these processes, mistakes are sometimes made....
The Science Behind A More Meaningful Understanding Of Sexual Orientation
People who are attracted to others of the same sex develop their orientation before they are born. This is not a choice. And scientific evidence shows their parents cannot be blamed. Research proving ...
Primary structure
Biomolecular structure is the intricate folded, three-dimensional shape that is formed by a protein, DNA, or RNA molecule, and that is important to its function. The structure of these molecules is f...
Transcription (genetics)
Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase.Both RNA and DNA are nucleic acids, which use base pairs of nuc...

DNA replication
DNA replication is the process of producing two identical replicas from one original DNA molecule. This biological process occurs in all living organisms and is the basis for biological inheritance. ...
Reverse transcription
A Reverse transcriptase (RT) is an enzyme used to generate complementary DNA (cDNA) from an RNA template, a process termed reverse transcription. It is mainly associated with retroviruses. It should b...
