History of evolutionary thought
Evolutionary thought, the conception that species change over time, has roots in antiquity, in the ideas of the ancient Greeks, Romans, and Chinese as well as in medieval Islamic science. With the beg...

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.
Calls vs. Balls: "Monkey Balls" Show Why Men Overcompensate
Howler monkeys are about the size of a small dog, weighing around seven kilos, yet they are among the loudest terrestrial animals on the planet, and can roar...
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:...
Scientists Discover Genetic, Biologic Cause Of Schizophrenia
Scientists already knew that the C4 gene generates a protein that the body uses to mark pathogens so that the immune system destroys them. But, importantly, it’s also used during synaptic pruning, a p...
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...
Calls Vs. Balls: Monkeys With More Impressive Roars Produce Less Sperm
Howler monkeys are about the size of a small dog, weighing around seven kilos, yet they are among the loudest terrestrial animals on the planet, and can roar at a similar acoustic frequency to tigers....
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...
Researchers Develop Novel Theoretical Approach To Reduce Antibiotic Resistance
It is estimated that each year in the United States 2 million people become infected with bacteria that are resistant to one or more types of antibiotics, and at least 23,000 people will die because ...
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...
Evolutionary ideas of the Renaissance and Enlightenment
Evolutionary ideas of the Renaissance and the Enlightenment developed as natural history became more sophisticated during the 17th and 18th centuries, and as the scientific revolution and the rise of ...

Natural selection
Natural selection is the gradual process by which heritable biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential repr...

Darwinism
Darwinism is a theory of biological evolution developed by Charles Darwin and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variatio...
Modern evolutionary synthesis
The modern evolutionary synthesis is a 20th-century synthesis of ideas from several fields of biology which provides a widely accepted account of evolution. It is also referred to as the new synthesis...
History of molecular evolution
The history of molecular evolution starts in the early 20th century with "comparative biochemistry", but the field of molecular evolution came into its own in the 1960s and 1970s, following the rise o...
