Scientists Reveal How Cell Corrects Errors Made in Gene Transcription

May 3, 2016 — The dynamics of the RNA polymerase II (Pol II) backtracking process is poorly understood. Scientists have now built a Markov State Model from extensive molecular dynamics simulations to identify ... read more

Nuclear Pores Captured on Film

May 2, 2016 — Using an ultra fast-scanning atomic force microscope, a team of researchers has filmed “living” nuclear pore complexes at work for the first time. Nuclear pores are molecular machines that ... read more

Apr. 29, 2016 — Scientists combined three biopolymers, chitosan and agarose (polysaccharides), and a protein gelatine, as the materials to produce tissue engineering scaffolds and demonstrated the enhancement of ... read more

Researchers Use Viral Particles to Trap Intact Mammalian Protein Complexes

Apr. 29, 2016 — Belgian scientists report their development of Virotrap, a viral particle sorting approach for purifying protein complexes under native conditions. This method catches a bait protein together with ... read more

New Technique Spots Active Motion in Cells

Apr. 28, 2016 — A noninvasive data analysis technique has been developed that can discern whether an object's random motion is actively or thermally ... read more

Apr. 25, 2016 — An unexpected link between cellular metabolic and recycling processes points to new cancer therapies. This cellular fuel gauge is a protein complex called AMPK that oversees energy input and output ... read more

How Researchers Teach Bacteria New Behaviors

Apr. 25, 2016 — Researchers working in the field of synthetic biology use components that occur in nature and combine them in a new way. This is how bacteria acquire functions that they hadn’t previously ... read more

Apr. 22, 2016 — Studying a new type of pinhead-size, lab-grown brain made with technology first suggested by three high school students, researchers have confirmed a key way in which Zika virus causes microcephaly ... read more

Apr. 22, 2016 — Consuming fructose, a sugar that's common in the Western diet, alters hundreds of genes that may be linked to many diseases, life scientists report. However, they discovered good news as well: ... read more

Apr. 22, 2016 — Cells in the body exchange a number of signals with their surroundings. Deficient signal pathways may adversely affect the function of cells and cause diseases. However, we hardly know more than the ... read more

Apr. 22, 2016 — Timing is everything when it comes to the development of the vertebrate face. In a new study, researchers have identified the roles of key molecular signals that control this critical ... read more

Immune Cells in Organ Cavities Play Essential Role in Fast Tissue Repair

Apr. 21, 2016 — While scientists have known for many years that there are cells living in the cavities surrounding various organs such as the heart, lung and liver, their function has remained unknown. A recent ... read more

The Importance of Resting Phases in B Cell Development

Apr. 21, 2016 — Everyone preparing for the London Marathon likely knows that to perform their best during the event, they need to rest up now. New research describes a new mechanism through which B cells ensure that ... read more

Apr. 21, 2016 — Researchers used genetically modified bacteria as a model to help explain how a developing animal keeps all of its parts and organs in the same general proportions as every other member of its ... read more

Apr. 21, 2016 — Research scientists has demonstrated how it is possible to suppress the resistance of fungi to antifungal drugs. The experiments were conducted on the cells of baker's yeast, a common fungal ... read more

Unique Regulatory Pattern That Promotes Essential Cell Function Found

Apr. 21, 2016 — Scientists and clinicians often encounter road blocks in designing specific treatments for diseases like cancer or developmental disorders because proteins that regulate cell functions through ... read more

Plant Signals Travel Different Routes to Turn on Defense

Apr. 21, 2016 — Faced with a pathogen, important signaling chemicals within plant cells travel different routes to inform the plant to turn on its defense mechanisms, according to a recent ... read more

Apr. 21, 2016 — The LEAFY protein, a transcription factor responsible for flower development, is able to assemble itself in small chains made up of several proteins. This mechanism allows it to bind to and activate ... read more

Apr. 21, 2016 — A plant-based polyphenol promotes the migration of Mesenchymal Stem Cells (MSCs) in blood circulation and accumulates them in damaged tissues to improve wound healing, scientists have found. It is ... read more

Scientists Sharpen View of Gene Transfer Between Pathogenic Bacteria

Apr. 20, 2016 — Bacteria possess the ability to take up DNA from their environment, a skill that enables them to acquire new genes for antibiotic resistance or to escape the immune response. Scientists have now ... read more
