Sep. 23, 2016 — In the female dog, cells of the uterus can accumulate lipid droplets to form so-called foamy epithelial cells during late metoestrus. These cells produce a hormone that is involved in the ... read more

Researchers Describe Key Protein Structure and a Drug Prototype That Could Assist Therapeutic Development

Sep. 21, 2016 — The three-dimensional, atomic structure of an important cell receptor molecule linked to the development of several diseases has now been described in a new ... read more

Scientists Discover Interplay of Yin-Yang Antagonists Vital for Cell Division

Sep. 20, 2016 — A pair of large enzyme complexes attack each other in turn to form a molecular switch, which is essential for cell division, a new study has ... read more

Sep. 19, 2016 — A scientist is exploring the adaptations that have allowed corn to be cultivated in a wide range of elevations and environments across the Americas. Comparing corn varieties adapted to low elevations ... read more

How a Bacterial Virulence Factor Promotes Its Own Secretion

Sep. 18, 2016 — Many bacteria depend on their ability to attach, or adhere, to our cells for the ability to cause disease. When their survival means disease for us, we often turn to antibiotics, but his miracle ... read more

Genes Essential to Life Found in Mouse Mutants Are Related to Many Human Disease Genes

Sep. 16, 2016 — Mutant traits have, for the first time, been identified in the mouse for 52 human disease genes. This significantly contributes to the understanding of the genetic bases for some human ... read more

Sep. 16, 2016 — About one-third of 1751 genes studied in the first comprehensive survey of the mouse genome are essential to life, according to new research. Mutations of these genes cause death at the embryo stage. ... read more

Sep. 16, 2016 — Millions of years ago, the ancestor of modern rattlesnakes was endowed with a genetic arsenal of toxic weaponry. But in a relatively short period of evolutionary time, different types of snakes kept ... read more

Sep. 15, 2016 — Researchers have identified a patient in Haiti with a serious mosquito-borne illness that has never before been reported in the Caribbean ... read more

The End Justifies the Means, Even at the Cellular Level

Sep. 15, 2016 — Each of our cells is endowed with a miniature clock composed of a set of ‘clock genes’. During the day, the expression of these genes varies, and this fluctuation influences many biological ... read more

Urban Shorelines Support More Animal Life, Floating DNA Reveals

Sep. 15, 2016 — Researchers are now able to capture the cells of animals, sequence their DNA and identify which species were present in water at a point in time. A new University of Washington study is the first to ... read more

Shedding Light on the Limits of the Expanded Genetic Code

Sep. 15, 2016 — In 2014, scientists made a huge news splash when they reported the ability to grow bacteria with an expanded genetic code. Critics feared the rise of unnatural creatures; others appreciated the ... read more

Decelerated Protein Synthesis, Degradation in a Worm With Doubled Lifespan

Sep. 14, 2016 — The gradual accumulation of damage to all kinds of molecules in the cell is often considered as the primary cause of aging. This escalating damage could cause the progressive failure of cell ... read more

Rapid Gene Analysis Method Accelerates Photosynthesis Studies

Sep. 13, 2016 — Researchers used a rapid screening technique that genetically engineers plants -- in real time -- to investigate how to help plants realize their full ... read more

Sep. 13, 2016 — Eggs can be 'tricked' into developing into an embryo without fertilization, but the resulting embryos, called parthenogenotes, die after a few days because key developmental processes ... read more

A New Tumor Suppressor Gene for Breast Cancer in Mice

Sep. 13, 2016 — Researchers have revealed a role for an X-linked protein kinase Nrk in terminating the proliferation of mammary epithelial cells during pregnancy and thereby preventing breast tumorigenesis in ... read more

Scientists Use Genetic Analysis to Forecast Spatial Expansion of Rabies in Peru

Sep. 12, 2016 — Rabies is likely to appear on the Pacific coast of Peru—an area where it currently does not occur—within four years, according to a report by an international team of ... read more

Sep. 12, 2016 — Genetic modification of plants might be controversial in commercial applications, but it is undeniably useful for research purposes. Despite years of effort, it has been remarkably difficult to ... read more

Sep. 12, 2016 — Experiments have shown that it is remarkably easy for protein-like, two-dimensional structures -- amyloids -- to form from basic building blocks. This discovery supports the researchers' ... read more

Revving the Microbial Engine: Horsepower Versus Fuel Efficiency in Bacterial Genomes

Sep. 12, 2016 — Microbes that can reproduce rapidly in times of plenty have an evolutionary stockpile of extra genes that allows them to quickly respond to changing conditions such as oil spills or outbreaks of ... read more
