The article profiles a project addressing a central issue in reform-driven STEM education–the need to align educational experiences with real-world STEM. We profile an interdisciplinary project which aimed for authenticity by: 1) purposefully designing an authentic PBL project and...

Structural distortions in M[E(SiMe₃)₂]₃ complexes (M = group 15, f-element; E = N, CH): is three a crowd?.

Inorganic chemistry

Boyde NC, Chmely SC, Hanusa TP, Rheingold AL, Brennessel WW.
PMID: 25171144
Inorg Chem. 2014 Sep 15;53(18):9703-14. doi: 10.1021/ic501232z. Epub 2014 Aug 29.

The tris(bistrimethylsilylamido) species P[N(SiMe3)2]3 (1) and As[N(SiMe3)2]3 (2) have been prepared through halide metathesis in high yield. Their single crystal X-ray structures, along with that of Sb[N(SiMe3)2]3 (3), complete the series of structurally authenticated group 15 M[N(SiMe3)2]3 complexes (the...

Direct observation of active material interactions in flowable electrodes using X-ray tomography.

Faraday discussions

Hatzell KB, Eller J, Morelly SL, Tang MH, Alvarez NJ, Gogotsi Y.
PMID: 28474019
Faraday Discuss. 2017 Jul 01;199:511-524. doi: 10.1039/c6fd00243a. Epub 2017 May 05.

Understanding electrical percolation and charging mechanisms in electrochemically active biphasic flowable electrodes is critical for enabling scalable deionization (desalination) and energy storage. Flowable electrodes are dynamic material systems which store charge (remove ions) and have the ability to flow....

The PIN domain endonuclease Utp24 cleaves pre-ribosomal RNA at two coupled sites in yeast and humans.

Nucleic acids research

Wells GR, Weichmann F, Colvin D, Sloan KE, Kudla G, Tollervey D, Watkins NJ, Schneider C.
PMID: 27034467
Nucleic Acids Res. 2016 Jun 20;44(11):5399-409. doi: 10.1093/nar/gkw213. Epub 2016 Mar 31.

During ribosomal RNA (rRNA) maturation, cleavages at defined sites separate the mature rRNAs from spacer regions, but the identities of several enzymes required for 18S rRNA release remain unknown. PilT N-terminus (PIN) domain proteins are frequently endonucleases and the...

Septins Focus Cellular Growth for Host Infection by Pathogenic Fungi.

Frontiers in cell and developmental biology

Momany M, Talbot NJ.
PMID: 28424773
Front Cell Dev Biol. 2017 Apr 05;5:33. doi: 10.3389/fcell.2017.00033. eCollection 2017.

One of the key challenges faced by microbial pathogens is invasion of host tissue. Fungal pathogens adopt a number of distinct strategies to overcome host cell defenses, including the development of specialized infection structures, the secretion of proteins that...

Hill classification is superior to the axial length of a hiatal hernia for assessment of the mechanical anti-reflux barrier at the gastroesophageal junction.

Endoscopy international open

Hansdotter I, Björ O, Andreasson A, Agreus L, Hellström P, Forsberg A, Talley NJ, Vieth M, Wallner B.
PMID: 27004249
Endosc Int Open. 2016 Mar;4(3):E311-7. doi: 10.1055/s-0042-101021. Epub 2016 Feb 10.

BACKGROUND AND STUDY AIMS: The pathogenesis of gastroesophageal reflux disease (GERD) is multifactorial, including the mechanical anti-reflux barrier of the gastroesophageal junction. This barrier can be evaluated endoscopically in two ways: by measuring the axial length of any hiatal...

The threat of antimalarial drug resistance.

Tropical diseases, travel medicine and vaccines

Hanboonkunupakarn B, White NJ.
PMID: 28883954
Trop Dis Travel Med Vaccines. 2016 Jul 07;2:10. doi: 10.1186/s40794-016-0027-8. eCollection 2016.

The battle between man and malaria has continued for thousands of years. Antimalarial drugs are essential weapons to fight the disease, but their efficacy is threatened by drug resistance which continues to emerge creating a major obstacle to malaria...

The role of necroptosis in atherosclerotic disease.

JACC. Basic to translational science

Leeper NJ.
PMID: 28480338
JACC Basic Transl Sci. 2016 Oct;1(6):548-550. doi: 10.1016/j.jacbts.2016.08.002.

It is now known that cells don't always die by apoptosis, but can also undergo a process known as programmed cell necrosis, or necroptosis. In a study recently published in
