MarkerMiner 1.0: An Easy-to-Use Bioinformatics Platform for DNA Analysis in Angiosperms

Apr. 30, 2015 — Researchers have developed MarkerMiner, a new software that simplifies analysis of next-generation sequencing data in angiosperms. MarkerMiner is an automated, open-source, bioinformatics workflow ... read more

Settling an Old Debate: Researchers Solve a Lingering Mystery of Cancer Cell Biology

Apr. 30, 2015 — German biologist Theodor Boveri observed early in the last century that cancer cells often harbor multiple copies of a subcellular structure that he had previously named the centrosome. He was also ... read more

Apr. 30, 2015 — A simple chemical compound kills several major fungi that affect human health, researchers report. The compound also may have applications for fungal diseases that affect wheat and rice ... read more

Role of Telomeres in Plant Stem Cells Discovered

Apr. 30, 2015 — The development of an innovative technology that enables the monitoring of telomeres at the cellular level in plants has been described in a new article. The technique allows to demonstrate, for the ... read more

Apr. 30, 2015 — Bats fly with breathtaking precision because their wings are equipped with highly sensitive touch sensors, cells that respond to even slight changes in airflow, researchers ... read more

Apr. 30, 2015 — When it comes to cracking nuts, wild bearded capuchin monkeys are more skilled than anyone had given them credit for, according to ... read more

Apr. 30, 2015 — Biochemists have discovered a protein that regulates the hierarchical organization of ribosome development. Ribosomes are complexly structured cellular nanomachines consisting of four ribonucleic ... read more

Apr. 30, 2015 — Researchers have perfected a noninvasive "chemogenetic" technique that allows them to switch off a specific behavior in mice -- such as voracious eating -- and then switch it back on. The ... read more

Are We Exterminating One African Elephant by Not Recognizing Two?

Apr. 30, 2015 — Within the past week, Thailand officials seized seven tons of ivory, representing the slaughter of hundreds of African elephants for illegal trade. While recent reports say that poaching far exceeds ... read more

Evolution: The Secrets of the Brachiopod Shell

Apr. 30, 2015 — Researchers have carried out the first detailed study of the molecular mechanisms responsible for formation of the brachiopod shell. Comparison with shell synthesis in other groups reveals the deep ... read more

Apr. 30, 2015 — Researchers have demonstrated for the first time that bacteriophages (bacterial viruses) carry genetic instructions for proteins that mediate the transport of their DNA to specialized replication ... read more

Apr. 29, 2015 — The human body is a cross between a factory and a construction zone -- at least on the cellular level. Certain proteins act as project managers, which direct a wide variety of processes and determine ... read more

Apr. 29, 2015 — Studying fruit fly larvae, scientists have mapped the entire neural circuit involved in combining vibration and pain sensations used in triggering an escape behavior. Combining information across ... read more

How the Lack of Specific Proteins Affects Development of Filamentous Fungi

Apr. 29, 2015 — Fungi can have a great economic impact. In industry, they are used as a source of enzymes or antibiotics. But they can also cause considerable economic damage as they are responsible for infections ... read more

Apr. 29, 2015 — Recombination, or crossing-over, occurs when sperm and egg cells are formed and segments of each chromosome pair are interchanged. This process plays an crucial role in the maintenance of genetic ... read more

Apr. 29, 2015 — Biophysicists are working toward an energy-landscape theory for chromosomes. The theory could help scientists understand the genomic roots of gene regulation, DNA replication and cell ... read more

Research Prompts Rethink of Enzyme Evolution

Apr. 29, 2015 — There is a need for a fundamental rethink of the evolutionary path of enzymes, the proteins vital to all life on Earth, new research suggests. Enzymes catalyze a vast array of biologically relevant ... read more
