DAP kinase and DRP-1 mediate membrane blebbing and the formation of autophagic vesicles during programmed cell death
Death-associated protein kinase (DAPk) and DAPk-related protein kinase (DRP)-1 proteins are Ca+2/calmodulin–regulated Ser/Thr death kinases whose precise roles in programmed cell death are still mostly unknown. In this study, we dissected the subcellular events in which these kinases are involved during cell death. Expression of each of these DAPk subfamily members in their activated forms triggered two major cytoplasmic events: membrane blebbing, characteristic of several types of cell death, and extensive autophagy, which is typical of autophagic (type II) programmed cell death. These two different cellular outcomes were totally independent of caspase activity. It was also found that dominant negative mutants of DAPk or DRP-1 reduced membrane blebbing during the p55/tumor necrosis factor receptor 1–induced type I apoptosis but did not prevent nuclear fragmentation. In addition, expression of the dominant negative mutant of DRP-1 or of DAPk antisense mRNA reduced autophagy induced by antiestrogens, amino acid starvation, or administration of interferon-γ. Thus, both endogenous DAPk and DRP-1 possess rate-limiting functions in these two distinct cytoplasmic events. Finally, immunogold staining showed that DRP-1 is localized inside the autophagic vesicles, suggesting a direct involvement of this kinase in the process of autophagy
Advancing support for intergroup equality via a self-affirmation campaign
Members of historically advantaged groups are often unwilling to support actions or policies aimed at reducing inequality between advantaged and disadvantaged groups, even if they generally support the principle of equality. Based on past research, we suggest a self-affirmation intervention (an intervention in which people reflect on a positive trait or value in order to affirm their positive self-image) may be effective for increasing the willingness of advantaged group members to address inequality. Importantly, while self-affirmation has been only operationalized as a written exercise in the past, in this project, we adapt it into video messages for use in public campaigns. In Study 1, we experimentally tested an initial video adaptation of self-affirmation and found that it was effective in increasing the willingness of advantaged group members to address inequality in the context of Jewish–Arab relations in Israel. Based on this study, two NGOs developed a real campaign video and used it in their public campaign, and we tested this applied intervention (in Study 2) and found it to be effective compared to a control condition that only presented information about inequality. Together, these studies represent the first implementation of self-affirmation in real-world campaigns and indicate that it can be an effective way to increase support for action to address inequality.</p

Understanding the Properties of Generated Corpora
Models for text generation have become focal for many research tasks and
especially for the generation of sentence corpora. However, understanding the
properties of an automatically generated text corpus remains challenging. We
propose a set of tools that examine the properties of generated text corpora.
Applying these tools on various generated corpora allowed us to gain new
insights into the properties of the generative models. As part of our
characterization process, we found remarkable differences in the corpora
generated by two leading generative technologies
The Soreq Applied Research Accelerator Facility (SARAF) - Overview, Research Programs and Future Plans
The Soreq Applied Research Accelerator Facility (SARAF) is under construction
in the Soreq Nuclear Research Center at Yavne, Israel. When completed at the
beginning of the next decade, SARAF will be a user facility for basic and
applied nuclear physics, based on a 40 MeV, 5 mA CW proton/deuteron
superconducting linear accelerator. Phase I of SARAF (SARAF-I, 4 MeV, 2 mA CW
protons, 5 MeV 1 mA CW deuterons) is already in operation, generating
scientific results in several fields of interest. The main ongoing program at
SARAF-I is the production of 30 keV neutrons and measurement of Maxwellian
Averaged Cross Sections (MACS), important for the astrophysical s-process. The
world leading Maxwellian epithermal neutron yield at SARAF-I (
epithermal neutrons/sec), generated by a novel Liquid-Lithium Target (LiLiT),
enables improved precision of known MACSs, and new measurements of
low-abundance and radioactive isotopes. Research plans for SARAF-II span
several disciplines: Precision studies of beyond-Standard-Model effects by
trapping light exotic radioisotopes, such as He, Li and
Ne, in unprecedented amounts (including meaningful studies already
at SARAF-I); extended nuclear astrophysics research with higher energy
neutrons, including generation and studies of exotic neutron-rich isotopes
relevant to the rapid (r-) process; nuclear structure of exotic isotopes; high
energy neutron cross sections for basic nuclear physics and material science
research, including neutron induced radiation damage; neutron based imaging and
therapy; and novel radiopharmaceuticals development and production. In this
paper we present a technical overview of SARAF-I and II, including a
description of the accelerator and its irradiation targets; a survey of
existing research programs at SARAF-I; and the research potential at the
completed facility (SARAF-II).Comment: 32 pages, 31 figures, 10 tables, submitted as an invited review to
