Tools in science

27-Mar-2017 | Anna Zakrisson, Christine Kronfoth, Acta Physiologica, 2017

Abstract When talking to non‐scientists, it is rather amusing how much the Victorian view of a scientist still lingers. Many people, still view us [scientists] as crazy people working in basements (alright, that might contain some truth), who solve unholy puzzles using tools like beakers with ...


Directly lighting up RNA G-quadruplexes from test tubes to living human cells

16-Nov-2015 | Shujuan Xu; Qian Li; Junfeng Xiang; Qianfan Yang; Hongxia Sun; Aijiao Guan; Lixia Wang; Yan Liu; Lijia Yu; Yunhua Sh ..., Nucleic Acids Research, 2015

RNA G-quadruplexes (G4s) are one of the key components of the transcriptome that act as efficient post-transcriptional regulatory elements in living cells. To conduct further studies of the unique biological functions of RNA G4s, techniques need to be developed that can efficiently recognize RNA ...


Multistrain probiotics production by co‐culture fermentation in a lab‐scale bioreactor

14-Oct-2015 | Manoj Jangra, Prasanna D. Belur, Larysa B. Oriabinska, Olexii M. Dugan, Engineering in Life Sciences, 2015

Most commercial probiotic products intended for pharmaceutical applications consist of combinations of probiotic strains and are available in various forms. The development of co‐culture fermentation conditions to produce probiotics with the correct proportion of viable microorganisms would ...


Non‐Isothermal Kinetic Models of Degradation of S‐Methylmethionine

14-Jul-2015 | Yarong Huang, Johannes Tippmann, Thomas Becker, Journal of Food Process Engineering, 2015

Abstract Dimethyl sulfide (DMS), which has a characteristic taste and aroma of cooked celery, is one of the most studied off‐flavors in wort and beer. Although there have been many kinetic studies conducted with different wort boiling systems under isothermal conditions, the results are ...


[Retrospective] Retrospective: Robert G. Edwards (1925–2013)

22-May-2013 | Susan J. Fisher, Linda C. Giudice, Science , 2013

The work of a pioneer of in vitro fertilization led to the first "test-tube baby" and changed the field of human reproductive biology.


[News of the Week] Newsmakers

24-Apr-2013 | Science , 2013

British physiologist Robert Edwards died last week at age 87, nearly 35 years after he helped usher the first "test-tube" baby into the world.


Profile of Eckard Albert Friedrich Wimmer [Profiles]

05-Feb-2013 | Sujata Gupta, Proceedings of the National Academy of Sciences current issue, 2013

The finding caused an uproar. Researchers at Stony Brook University in New York had engineered poliovirus in a test tube (1). The discovery, led by Eckard Wimmer, elected in 2012 to the National Academy of Sciences, dispelled the belief that viruses require a live host to grow and ...


Tangled bank of experimentally evolved Burkholderia biofilms reflects selection during chronic infections [Microbiology]

15-Jan-2013 | Charles C. Traverse; Leslie M. Mayo-Smith; Steffen R. Poltak; Vaughn S. Cooper, Proceedings of the National Academy of Sciences current issue, 2013

How diversity evolves and persists in biofilms is essential for understanding much of microbial life, including the uncertain dynamics of chronic infections. We developed a biofilm model enabling long-term selection for daily adherence to and dispersal from a plastic bead in a test tube. Focusing ...


Multimolecule test-tube simulations of protein unfolding and aggregation [Biophysics and Computational Biology]

30-Oct-2012 | Michelle E. McCully; David A. C. Beck; Valerie Daggett, Proceedings of the National Academy of Sciences current issue, 2012

Molecular dynamics simulations of protein folding or unfolding, unlike most in vitro experimental methods, are performed on a single molecule. The effects of neighboring molecules on the unfolding/folding pathway are largely ignored experimentally and simply not modeled computationally. Here, we ...
