Ominous-appearing serosal findings on PSMA imaging: careful clinical judgement should complement molecular imaging
We read with great interest the Clinical Outlook by Abel et al. (Abel, M. L. et al. Ominous-appearing serosal findings on PSMA imaging might belie indolent clinical course. Nat. Rev. Urol. 23, 353–354; 2026)1, in which they highlight the expanding spectrum of prostate cancer manifestations detected by molecular imaging and discuss the clinical course of ominous-appearing serosal findings on prostate-specific membrane antigen (PSMA) imaging.

Prostatic acid phosphatase: a rediscovered target in prostate cancer
Prostatic acid phosphatase (ACP3) is overexpressed in prostate cancer and synthesized at low levels in most physiological tissues. The first in-human application of a radioligand targeting ACP3 for staging of prostate cancer through positron emission tomography showed promising results in a head-to-head comparison with an established prostate-specific membrane antigen (PSMA) radiotracer. ACP3 could be a complementary or alternative target to PSMA for imaging and therapy of prostate cancer.

PSMA PET Evaluation with a Deep Learning Platform Compared with a Standard Image Viewer and Histopathology
Standardized prostate-specific membrane antigen (PSMA) PET/CT evaluation and reporting was introduced to aid interpretation, reproducibility, and communication. Artificial intelligence may enhance these efforts. This study aimed to evaluate the performance of aPROMISE, a deep learning segmentation and reporting software for PSMA PET/CT, compared with a standard image viewer (IntelliSpace Portal [ISP]) in patients undergoing PSMA-radioguided surgery.

PROMISE V2 — something new, something old and something borrowed - Nature Reviews Urology
Prostate-specific membrane antigen-PET has become a valuable diagnostic tool. The second version of the Prostate Cancer Molecular Imaging Standardized Evaluation framework is the next step towards a standardized evaluation and reporting system from primary staging to reassessment of advanced prostate cancer. The emergence of prostate-specific membrane antigen (PSMA) imaging has revolutionized prostate cancer diagnostics in the past decade1.

When branding turns toxic: a theoretical framework for modern extreme-right brand networks
Introduction In 2014, a new coffee company was founded in the United States. The privately owned Black Rifle Coffee Company (BRCC) developed its corporate identity around a distinct pro-veteran, pro-military, pro-police, and pro-gun marketing aesthetic, which directly addressed the conservative right consumer base. BRCC’s coffee and associated merchandise were styled to be part of a way of life closely connected to a hypermasculine ‘warrior’ identity.

Dying for the Cause? Not really. The Far-Right has its own take on “martyrdom”.
Right Now! Suicide attacks are virtually absent in far-right terrorism. A recent study of the subcultural, strategic, and historic references to martyrdom, self-sacrifice, and suicide in the contemporary far right shows the potential reasons for this, highlighting the peculiar political mythology of “martyrdom” that characterizes this extremist environment.

Dying for the cause? The logic and function of ideologically motivated suicide, martyrdom, and self-sacrifice within the contemporary extreme right
ABSTRACT In recent years, extreme right-wing militancy and terrorism have increasingly become the major source of violent attacks, killings, and threats in many Western countries. Yet, the characteristics and logic of right-wing terrorism remain poorly understood. One aspect virtually unexplored is the apparent lack of suicide terror tactics within far-right terrorism. Suicide terrorism has been attributed mainly to religious and ethno-separatist terrorist organizations.

No other country in Western Europe has in recent decades experienced as much severe and deadly right-wing violence as Germany. Moreover, the nature of this violence is more complex than in other countries, making it even more difficult to prevent.

A Threat from Within? Exploring the Link between the Extreme Right and the Military
Daniel Koehler 7 Oct 2019 Download Right-wing violence and terrorism have slowly gained more academic and public attention in recent years, with an increase in anti-immigration and anti-government organised violence from the extreme right in most Western countries. Some evidence exists that right-wing extremists have attempted to infiltrate the military in their home countries to gain access to tactical training, weapons, and to recruit highly skilled new members.

Violence and Terrorism from the Far-Right: Policy Options to Counter an Elusive Threat
Daniel Koehler 27 Feb 2019 Download Extreme right-wing violence and terrorism are a growing threat to Western societies. This form of political violence is also quite elusive and differs from others (e.g. jihadist violence) in some key characteristics. Since the September 11 attacks, policy makers, law enforcement and intelligence agencies as well as researchers have focused most of their attention on Islamic extremist violence and terrorism.

¿Cuál es el recurso que más se pasa por alto en la lucha contra el extremismo? Las madres
STUTTGART (Alemania) - Cuando el joven Akhror Saidakhmetov, de 19 años, empezó a salir con dos hombres mayores que él y a hablar de extender la yihad en Siria, su madre le quitó el pasaporte. Más adelante, como informa el Washington Post, cuando el joven le suplicó a su madre que le devolviera el pasaporte -admitiendo que quería unirse al Estado Islámico-, ella le colgó el teléfono.
When 19-year-old Akhor Saidakhmetov started talking about waging jihad in Syria, his mother took away his passport. When he begged to get it back, she hung up the phone. Mothers like her may be the first, last and best approach to stopping militant recruiters, but law enforcement often leaves them out of their counterterrorism efforts in the U.S. and Europe.There are three different approaches a country can take against violent extremism and terrorism: prevention, repression and intervention.
O recurso mais negligenciado no combate ao extremismo? As mães
Quando Akhror Saidakhmetov, 19, começou a sair com dois homens mais velhos e a falar sobre jihad na Síria, sua mãe tirou seu passaporte. Mais tarde, como relata o Washington Post, quando ele pediu o documento de volta -- admitindo que queria entrar para o chamado Estado Islâmico -- ela desligou o telefone.
Who can stop a jihadi? Try his mom.

Mothers like her may be the first, last, and best approach to stopping militant recruiters, but law enforcement often leaves them out of their counterterrorism efforts in the U.S. and Europe.
Editing Begins! | Voices
For the past several weeks, I’ve been living in New Xade without internet access, so I haven’t been able to update my blog. But in the relative quiet of village life, I’ve made the important transition into postproduction. Kebabonye, my field producer and translator, and I have been working nonstop on the edit – watching footage, transcribing it, and assembling the pieces into a coherent story. Here’s our humble workstation, tucked into the corner of my room.
Tumelo and the Central Kalahari Game Reserve
Sorry for the shortage of posts for the past month and a half. I have been living in New Xade without internet access and even made a trip to Metsiamanong in the Central Kalahari Game Reserve (CKGR), where there are no amenities – not even a borehole for water. It has been an interesting time, full of new experiences, fun times, and its fair share of challenges.
