Researchers have collaborated to craft a request that could fundamentally alter how the antibodies used in research are identified.

New technique allows scientists to track proteins known to create memories.

Sites where DNA is damaged may cause a molecule that slides along the DNA strand to scan for damage to slow on its patrol, delaying it long enough to recognize and initiate repair. The finding suggests that the delay itself may be the key that allows the protein molecule to find its target, according to researchers at the University of Illinois at Chicago.

In a new study, Sanford-Burnham Medical Research Institute researchers have used human pluripotent stem cells to generate new hair. The study represents the first step toward the development of a cell-based treatment for people with hair loss. In the United States alone, more than 40 million men and 21 million women are affected by hair loss. The research was published online in PLOS ONE.

Ribonucleotides, units of RNA, can become embedded in genomic DNA during processes such as DNA replication and repair, affecting the stability of the genome by contributing to DNA fragility and mutability. Scientists have known about the presence of ribonucleotides in DNA, but until now had not been able to determine exactly what they are and where they are located in the DNA sequences.

Five genetic variants that influence the size of structures within the human brain have been discovered by an international team that included a Georgia State University researcher.

Scientists design bacteria reliant upon synthetic amino acids to contain genetically modified organisms.

Picking a needle out of a haystack might seem like the stuff of fairytales, but our brains can be electrically “tuned” to enable us to do a much better job of finding what we’re looking for, even in a crowded and distracting scene, new research indicates.

A team led by structural biologists at The Scripps Research Institute (TSRI) has taken a big step toward understanding the intricate molecular mechanism of a metabolic enzyme produced in most forms of life on Earth.

Open any introductory biology textbook and one of the first things you’ll learn is that our DNA spells out the instructions for making proteins, tiny machines that do much of the work in our body’s cells. Results from a study published on Jan. 2 in Science defy textbook science, showing for the first time that the building blocks of a protein, called amino acids, can be assembled without blueprints – DNA and an intermediate template called messenger RNA (mRNA). A team of researchers has observed a case in which another protein specifies which amino acids are added. 

Forgetfulness, it turns out, is all in the head. Scientists have shown that fading memory and clouding judgment, the type that comes with advancing age, show up as lost and altered connections between neurons in the brain. But new experiments suggest an existing drug, known as riluzole and already on the market as a treatment for ALS, may help prevent these changes.

Researchers report on a revolutionary new procedure that uses 3D printing and the body’s stem cells to regenerate knee meniscus, a tissue lining that acts as a natural cushion between the femur and tibia.
