Oct. 27, 2016 — By developing an atomic-scale picture of how the cancer-linked enzyme PP2A binds to other proteins, researchers have developed a new list of nearly 100 of its potential ... read more

Oct. 26, 2016 — Researchers have demonstrated how deregulation of an epigenetic mechanism that is active only in the early phases of neurogenesis triggers the subsequent death of neural ... read more

Structure of Key DNA Replication Protein Solved

Oct. 25, 2016 — A research team has solved the three-dimensional structure of a key protein that helps damaged cellular DNA repair itself. Investigators say that knowing the chemical structure of the protein will ... read more

Study Links Small RNA Molecule to Pregnancy Complication

Oct. 24, 2016 — A family of small RNA molecules affects the development of cells that give rise to the placenta -- an organ that transfers oxygen and nutrients from mother to fetus -- in ways that could contribute ... read more

Genetic Hallmarks of Acute Lymphoblastic Leukemia Subtype Uncovered

Oct. 24, 2016 — Genetic changes underlying a type of B-precursor acute lymphoblastic leukemia have now been identified by a research ... read more

Oct. 22, 2016 — A team of scientists has discovered that rare neurological syndromes for which there was no cause can be the result of variations in the gene ATAD3A. The study sheds light on the causes of these ... read more

Measuring the Forces of Biology

Oct. 21, 2016 — Biology, at the nitty-gritty level of motor proteins, DNA, and microtubules, takes its cue from physics. But while much is known about the biological components that form such cellular stuctures, ... read more

Oct. 21, 2016 — There are many disadvantages to using human cells in the initial stages of creating a new therapy. Scientists often have to test a large number of compounds in order to find one that is effective ... read more

New Testing Method Allows More Effective Diagnosis of Genetically Based High Cholesterol

Oct. 20, 2016 — A new genetic testing method called LipidSeq can identify a genetic basis for high-cholesterol in almost 70 per cent of a targeted patient population. Using next-generation sequencing (NGS) ... read more

Toxic Peptides Disrupt Membrane-Less Organelles in Neurodegenerative Disease

Oct. 20, 2016 — Scientists reveal how toxic peptides that arise due to amyotrophic lateral sclerosis and frontotemporal dementia target the integrity of membrane-less organelles and trigger ... read more

Oct. 20, 2016 — One day before ovulation, human oocytes begin to divide into what will become mature eggs. Ideally, eggs are packaged with a complete set of 23 chromosomes, but the process is prone to error, ... read more

Oct. 20, 2016 — Mathematical analysis has led researchers to a formula that can describe the movement of DNA inside living human cells. Using these calculations, researchers may be able to reveal the 3D architecture ... read more

Oct. 20, 2016 — Large swaths of DNA and its lesser-known cousin RNA are dotted by chemical tags that act like Post-It notes, providing additional instructions to the underlying genetic code. The most abundant of ... read more

Rac1 Protein Critical for Lung Development

Oct. 20, 2016 — A promising therapeutic target has been discovered for improving lung function in infants. The study shows that a protein called Rac1 is critical for the proper development of mammalian ... read more

Oct. 20, 2016 — Although only 10 percent of amyotrophic lateral sclerosis (ALS) cases are hereditary, a significant number of them are caused by mutations that affect proteins that bind RNA, a type of genetic ... read more

Oct. 20, 2016 — Zika virus infection leads to modifications of both viral and human genetic material, scientists have discovered. These modifications — chemical tags known as methyl groups — influence viral ... read more

Do Microbes Control Our Mood?

Oct. 20, 2016 — Our intestine hosts a complex ecosystem of bacteria; we call it the gut microbiota, which includes at least 1000 difference species. We get most of our gut microbes soon after birth, although there ... read more

Oct. 20, 2016 — Eukaryotic cells, including human cells, form paired condensed chromosomes before cell division. The paired chromosomes are then equally divided into the daughter cells. Prokaryotic cells, including ... read more

Neu5Gc in Red Meat and Organs May Pose a Significant Health Hazard

Oct. 19, 2016 — A non-human sialic acid sugar molecule common in red meat that increases the risk of tumor formation in humans is also prevalent in pig organs, with concentrations increasing as the organs are ... read more

Oct. 19, 2016 — Maintaining the ends of chromosomes, called telomeres, allows cells to continuously divide and achieve immortality. In a new study, researchers have developed a first-of-its- kind system to observe ... read more
