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

Screening Method Uncovers Drugs That May Combat Deadly Antibiotic-Resistant Bacteria

Apr. 29, 2016 — In recent years, hospitals have reported dramatic increases in the number of cases of the highly contagious, difficult-to-treat, and often deadly antibiotic-resistant bacteria carbapenem-resistant ... 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

Apr. 29, 2016 — Twisted-winged parasites of the species Stylops ovinae reproduce using so-called traumatic insemination. To inseminate the eggs, the males injure the endoparasitic females with their hook-shaped ... 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. 28, 2016 — Everything you eat or drink affects your intestinal bacteria, and is likely to have an impact on your health. That is the finding of a large-scale study into the effect of food and medicine on the ... 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

Apr. 28, 2016 — Researchers have built a computer model of the interaction between different bacteria, and between bacteria and the gut wall. This has led them to explain how antibiotic-resistant microbes develop ... read more

Apr. 27, 2016 — An important model in studying human disease, the non-coding RNA of the canine genome is an essential starting point for evolutionary and biomedical studies, according to a new ... read more

Probiotics Stop Menopause-Like Bone Loss in Mice

Apr. 27, 2016 — Probiotic supplements protected female mice from the loss of bone density that occurs after having their ovaries removed, researchers have shown. The findings suggest that probiotic bacteria may have ... read more

Apr. 27, 2016 — The worst of the recent Ebola epidemic is over, but the threat of future outbreaks lingers. Monitoring the virus requires laboratories with trained personnel, which limits how rapidly tests can be ... read more

Apr. 27, 2016 — Longer parboiling processes at higher temperatures cause more micronutrients to migrate from a rice grain's outer bran layer into the starchy core, food scientists ... read more

Slow Worms React Quickly to Climate Change

Apr. 27, 2016 — Evolution can react surprisingly quickly to climate change -- at least for an important species of earthworms. For seven years, scientists have exposed the natural habitat of Enchytraeidae to a ... read more

Apr. 27, 2016 — Millions of native orchids are flourishing on the site of a former iron mine in New York's Adirondacks, suggesting that former industrial sites – typically regarded as blighted landscapes — ... read more

Apr. 27, 2016 — For the first time, scientists have demonstrated that an organism devoid of a nervous system is capable of learning. Biologists have succeeded in showing that a single-celled organism, the protist, ... read more

Zika Present in Americas Longer Than Previously Thought

Apr. 26, 2016 — The Zika virus was present in Haiti several months before the first Zika cases were identified in Brazil, according to new research by infectious-disease ... read more

Apr. 26, 2016 — Researchers in the United States recently completed the first comprehensive, multi-year study of honey bee parasites and disease as part of the National Honey Bee Disease Survey. The findings reveal ... 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
