Aug. 26, 2016 — Researchers have identified RNA-based biomarkers that distinguish between normal, aging hematopoietic stem cells and leukemia stem cells associated with secondary acute myeloid leukemia (sAML), a ... read more

Neuroscientists Stand Up for Basic Cell Biology Research

Aug. 25, 2016 — Clinical trials and translational medicine have certainly given people hope and rapid pathways to cures for some of humankind's most troublesome diseases, but now is not the time to overlook the ... read more

Aug. 25, 2016 — Functional human collagen has been impossible to create in the lab. Now, a team of researchers describes what may be the key to growing functional, natural collagen fibers outside of the body: ... read more

Aug. 25, 2016 — The process of energy generation by mitochondria is closely tied to intracellular calcium regulation by a membrane gateway inside mitochondria known as the mitochondrial Ca2+ uniporter (MCU). How MCU ... read more

New Technique Takes Guesswork out of IVF Embryo Selection

Aug. 25, 2016 — Researchers have successfully trialed a new technique that could aid the process of choosing the "best" embryo for implantation, helping to boost the chances of pregnancy success from the ... read more

A Look at the Molecular Quality Assurance Within Cells

Aug. 25, 2016 — Proteins fulfill vital functions in our body. They transport substances, combat pathogens, and function as catalysts. In order for these processes to function reliably, proteins must adopt a defined ... read more

Coffee Drinking Habits Can Be Written in Our DNA, Study Finds

Aug. 25, 2016 — Researchers have identified a gene that appears to curb coffee consumption. People with a DNA variation in a gene called PDSS2 tend to drink fewer cups of coffee, the study ... read more

Aug. 25, 2016 — Scientists are testing a drug that could boost levels of critical protective protein in brain. In the study, the team conducted tests in a mouse model of Alzheimer's disease by raising the ... read more

Aug. 25, 2016 — New research shows that certain primate stem cells have pluripotency superior to some types derived from mice. The study maps how pluripotency differs among mice, monkeys, and humans, and illustrates ... read more

Diet, Exercise, Both: All Work Equally to Protect Heart Health

Aug. 24, 2016 — For those who need to lose weight, taking off a few pounds by dieting, exercising or both is powerful protection against cardiovascular ... read more

Enigmatic Molecules Maintain Equilibrium Between Fighting Infection, Inflammatory Havoc

Aug. 24, 2016 — Special RNA molecules called long non-coding RNAs are key controllers for maintaining immune health when fighting infection or preventing inflammatory disorders. The discovery offers a potential drug ... read more

Barcodes Show the Blood Family Tree

Aug. 24, 2016 — By assigning a barcode to stem cells, researchers have made it possible to monitor large blood cell populations as well as individual blood cells, and study the changes over time. Among other things, ... read more

New Small Molecule Compounds Could Treat Ebola Virus Infection

Aug. 24, 2016 — Scientists have found Ebola's Achilles' heel: a new kind of chemical compound can block the protein Ebola uses to break out of cells and infect new cells. The compounds could potentially be ... read more

A New Path for Killing Pathogenic Bacteria

Aug. 24, 2016 — Bacteria that cause tuberculosis, leprosy and other diseases, survive by switching between two different types of metabolism. Scientists have now discovered that this switch is controlled by a ... read more

Mechanism That Alters Neural Excitability Offers Window Into Neuropsychiatric Disease

Aug. 23, 2016 — Researchers show, for the first time, that the well-known mechanism of gene expression control -- dynamic changes in DNA methylation -- is also involved in changes to the excitability of neural ... read more

Mutational Tug of War Over HIV's Disease-Inducing Potential

Aug. 23, 2016 — A study from AIDS researchers shows how the expected disease severity when someone is newly infected by HIV reflects a balance between the virus' invisibility to the host's immune system ... read more

New Zika Clone Could Be New Model for Developing Vaccine

Aug. 23, 2016 — Stopping the explosive spread of Zika virus -- which can lead to birth defects in babies born to infected mothers -- depends on genetic insights gleaned through new tools and models. Researchers ... read more

Aug. 22, 2016 — Researchers have discovered a rare and sometimes lethal inflammatory disease -- otulipenia -- that primarily affects young children. They have also identified anti-inflammatory treatments that ease ... read more

Aug. 22, 2016 — Researchers have succeeded in creating embryos with 'heteroplasmy,' or the presence of both maternal and paternal mitochondrial DNA. This new innovation will allow scientists to study ... read more

Esophageal Cancers Driven by 'Marginal Gain' Rather Than Speed

Aug. 22, 2016 — Scientists have shown that unexpectedly, esophageal cancer cells do not divide faster than their normal neighbors. But unlike normal cells, the tumor cells produce slightly more dividing daughter ... read more
