New Switch Decides Between Genome Repair, Death of Cells

Sep. 27, 2016 — The genetic information of every cell is encoded in the sequence of the DNA double helix. Double strand breaks in the DNA, which can be induced by radiation, are a dangerous threat to the cells, and ... read more

Sep. 26, 2016 — To fill in the blanks on mitochondria, researchers deleted 174 genes, one by one, in yeast. They then subjected the yeast to high-intensity mass spectrometry to measure unprecedented detail on ... 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

New Insights Into 'Plant Memories'

Sep. 21, 2016 — A special stretch of ribonucleic acid (RNA) called COOLAIR is revealing its inner structure and function to scientists, displaying a striking resemblance to an RNA molecular machine, territory ... read more

Sep. 21, 2016 — The microbial communities of toxic plant feeders in the Albufera lake in Valencia, Spain have been the focus of recent research. Aside from explaining the insects’ tolerance to a toxic diet, the ... read more

A Protein in Mosquito Spit Can Keep Dengue Virus in Check

Sep. 20, 2016 — Mosquito saliva influences transmission of viruses to a bitten mammalian host. For example, it contains factors that dampen the host immune response and so facilitate infection. A study reports on a ... read more

Sep. 20, 2016 — For plants and algae that carry on photosynthesis, light can be too much of a good thing. On a bright, sunny day, a plant might only be able to utilize 20 percent or less of absorbed sunlight. The ... read more

Sep. 20, 2016 — A new water bear protein can protect the DNA of human cultured cells from otherwise lethal amounts of radiation damage, say a group of researchers, providing part of the answer to why tardigrades can ... 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 — Plants have specialized immune receptor proteins on the surface of their cells, which detect specific molecular patterns, or ligands, on harmful bacteria. New research now reveals that these immune ... read more

Sep. 19, 2016 — Mosquitoes are more likely to feed on cattle than on humans if they carry a specific chromosomal rearrangement in their genome. This reduces their odds of transmitting the malaria parasite, according ... 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

Scientists Enhance Ability of Antibiotics to Defeat Resistant Types of Bacteria Using Molecules Called PPMOs

Sep. 17, 2016 — Researchers have developed a strategy to overcome a key defense that drug-resistant bacteria use to fend off antibiotic attack. Antibiotic resistance has become a major public health problem; the ... 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 — 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

Researcher Calls for Animal-Human Embryo Research to Proceed, but With Strong Animal Protections

Sep. 14, 2016 — A researcher calls for animal-human embryo research to proceed – but only with strong animal protections in place. So-called "chimera" research raises the hope of producing human organs ... read more
