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

Apr. 28, 2016 — Septin proteins in human and fungal cells can sense micron-scaled curves in the cell membrane, scientists ... read more

Apr. 28, 2016 — Researchers have identified a key action of a watershed gene critical to bone formation and the evolution of vertebrates. The Sp7 or Osterix gene more than likely emerged from an ancestral gene ... read more

Crop Advances Grow With Protection, Study Suggests

Apr. 27, 2016 — A team of researchers examined the impact of intellectual property protection in a new study. They found intellectual property protection benefits both plant breeders and ... read more

Apr. 27, 2016 — A strain of beneficial nitrogen-fixing bacteria has spread across California, researchers have discovered, demonstrating that beneficial bacteria can share some of the same features that are ... read more

Apr. 26, 2016 — A new study has found that one particular molecule found in reef ecosystems plays a similar immunological role in corals as it does in humans. From an evolutionary standpoint, this suggests the ... read more

Retroviral DNA Needs Time to Find Its Home, but Insertion Happens in a Blink

Apr. 26, 2016 — Retroviruses such as HIV must insert their viral DNA into host-cell DNA. A new study reveals details about the viral DNA's search for an insertion point. The findings could help improve ... read more

Apr. 26, 2016 — Scientists have solved the structure of the biological machinery used by a common virus to recognize and attack human host cells. The new structure gives scientists the first view of the glycoprotein ... 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

Apr. 25, 2016 — Mycobacteria cause a number of dangerous, difficult-to-treat diseases including leprosy and tuberculosis, and progress has been slow in eradicating them. But new strategies for combating these ... read more

Apr. 25, 2016 — A new method to accelerate isolation of plant disease resistance genes. The team has also identified a brand new source of blight resistance genes in Solanum americanum, a wild relative of the ... read more

Apr. 25, 2016 — Scientists have pioneered a new gene-detecting technology which, if deployed correctly could lead to the creation of a new elite variety of wheat with durable resistance to ... read more

Apr. 25, 2016 — Researchers have discovered which enzyme enables Escherichia coli bacterium to breathe. E. coli uses special enzymes to breathe, which are absent in the human body. This opens the door to the ... 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. 25, 2016 — The crucibles that bore out building blocks of life may have been, in many cases, not fiery cataclysms, but modest puddles. Researchers working with that hypothesis have achieved a significant ... 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
