Freeze frame: The Nobel Prize in Chemistry 2017 was jointly awarded to Jacques Dubochet, Joachim Frank, and Richard Henderson for "developing cryo-electron microscopy (cryo-EM) for the high-resolution structure determination of biomolecules in solution". This Highlight describes how the field of cryo-EM developed from the first transmission electron microscope in 1931 to the sophisticated technique of today.

In his Nobel Lecture, Anfinsen stated "the native conformation is determined by the totality of interatomic interactions and hence by the amino acid sequence, in a given environment." As aqueous solutions and membrane systems co-exist in cells, proteins are classified into membrane and non-membrane proteins, but whether one can transform one into the other remains unknown. Intriguingly, many well-folded non-membrane proteins are converted into "insoluble" and toxic forms by aging- or disease-associated factors, but the underlying mechanisms remain elusive...

This paper presents abundant empirical evidence to support the view that Santiago Ramón y Cajal was a pioneer of the emerging Psychology of Science discipline. Narrative analysis of his autobiography (Recollections of my Life) and some of his unspecialized works (Advice for a Young Investigator, The World from an Eighty-Year-Old's Point of View, and Café Chats) revealed that the Spanish histologist's interest in the psychology of scientists was part and parcel of a high-level, intellectual self-regulation strategy he applied on his path to success...

Living in rural Maine, Jeffrey Hall's own rhythm has been thrown upside down after he received a very unexpected call one morning on the award of this year's Nobel Prize in Physiology or Medicine. Together with Michael Rosbash and Mike Young, they were recognized "for their discoveries of molecular mechanisms controlling the circadian rhythm." Cell editor Marta Koch caught up with Jeff on a calm Sunday morning, when electricity at his house had just returned after recent storms. Annotated excerpts from their chat about behavior, misbehavior, and the challenges and joys of working with fruit flies, are presented below...

The 2017 Nobel Prize in Medicine or Physiology has been awarded to Jeffrey Hall, Michael Rosbash, and Michael Young for elucidating molecular mechanisms of the circadian clock. From studies beginning in fruit flies, we now know that circadian regulation pervades most biological processes and has strong ties to human health and disease.

The Royal Swedish Academy of Sciences awarded the 2017 Nobel Prize for Chemistry to Jacques Dubochet, Joachim Frank, and Richard Henderson for "developing cryoelectron microscopy for the high-resolution structure determination of biomolecules in solution." Achieving this goal, which required innovation, persistence, and uncommon physical insight, has broadened horizons for structural studies in molecular and cell biology.

This article reviews psychology's attempts to influence public attitudes about both the science and the profession of psychology. The early history of the profession is reviewed, and the efforts of the American Psychological Association (APA) to shape the public's perception of psychology are discussed. The rise of social media is reviewed, and important social media outlets relevant to psychology are identified. The activities of the Society for Media Psychology and Technology (APA Division 46) are illustrated, and the presidents of the Division are identified...

Immunoassays are antibody-based analytical methods for quantitative/qualitative analysis. Since the principle of immunoassays is based on specific antigen-antibody reaction, the assays have been utilized worldwide for diagnosis, pharmacokinetic studies by drug monitoring, and the quality control of commercially available products. Berson and Yalow were the first to develop an immunoassay, known as radioimmunoassay (RIA), for detecting endogenous plasma insulin [1], a development for which Yalow was awarded the Nobel Prize in Physiology or Medicine in 1977...

JAK2 abnormalities may serve as target for precision medicines in pediatric B-cell precursor acute lymphoblastic leukemia (BCP-ALL). In the current study we performed a screening for JAK2 mutations and translocations, analyzed the clinical outcome and studied the efficacy of two JAK inhibitors in primary BCP-ALL cells. Importantly, we identify a number of limitations of JAK inhibitor therapy. JAK2 mutations mainly occurred in the poor prognostic subtypes BCR-ABL1-like and non- BCR-ABL1-like B-other (negative for sentinel cytogenetic lesions)...

PURPOSE: To report on the outcome of placement of two bilateral zygomatic implants with an immediately loaded prosthesis. MATERIALS AND METHODS: A retrospective chart review was conducted of all patients treated with zygomatic implants between August 1, 2011 and June 6, 2016. All patients had at least two zygomatic implants placed bilaterally and immediately loaded with a provisional prosthesis the same day of implant placement. The implants were Nobel Biocare TiUnite or machined surface with lengths of 30 to 52...

The palladium-catalyzed Mizoroki-Heck reaction is arguably one of the most significant carbon-carbon bond-construction reactions to be discovered in the last 50 years, with a tremendous number of applications in the production of chemicals. This Nobel-Prize-winning transformation has yet to overcome the obstacle of its general application in a range of alkyl electrophiles, especially tertiary alkyl halides that possess eliminable β-hydrogen atoms. Whereas most palladium-catalyzed cross-coupling reactions utilize the ground-state reactivity of palladium complexes under thermal conditions and generally apply a single ligand system, we report that the palladium-catalyzed Heck reaction proceeds smoothly at room temperature with a variety of tertiary, secondary, and primary alkyl bromides upon irradiation with blue light-emitting diodes in the presence of a dual phosphine ligand system...

Cancers are "reprogrammed" to use a much higher rate of glycolysis (GLY) relative to oxidative phosphorylation (OXPHOS), even in the presence of adequate amounts of oxygenation. Originally identified by Nobel Laureate Otto Warburg, this hallmark of cancer has recently been termed metabolic reprogramming and represents a way for the cancer tissue to divert carbon skeletons to produce biomass. Understanding the mechanisms that underlie this metabolic shift should lead to better strategies for cancer treatments...

Christiane Nüsslein-Volhard is Director Emeritus at the Max Planck Institute for Developmental Biology in Tübingen, Germany. In 1995, she was awarded the Nobel Prize for Physiology and Medicine, along with Eric Wieschaus and Edward Lewis, for her work on the genetic control of embryogenesis using the fruit fly Drosophila melanogaster In the 1990s, she transitioned her lab to working with zebrafish (Danio rerio), using similar forward genetic approaches to those that had proved so successful in Drosophila to uncover key regulators of vertebrate development...

PURPOSE: The purpose of this study was to assess the density of interforaminal bone using quantitative computed tomography (QCT) in simulated case histories to be prescribed an All-on-Five fixed implant treatment protocol. MATERIALS AND METHODS: QCT scans from 30 edentulous patients (15 men and 15 women; mean age 63.33 ± 9.3 years) were analyzed using the Nobel Clinician software. Densities (in Hounsfield units [HU]) were recorded at the neck, middle part of the body, and apex of the lingual and buccal parts of proposed implant sites...
