18th - 22nd May - Queen Square Neurosurgery Review Course! 5 days of didactic lectures & mock FRCS vivas, delivered in a hybrid format by expert international faculty. Aimed at neurosurgical trainees and fellows of all grades. Ideal for FRCS exam preparation. Only a few places available for Face to Face with Viva! Registration & Info: shorturl.at/NiZ3Y

@TEQ_Neurosurg @EmDimitrakakis The legend himself, @EmDimitrakakis.

We are so excited to be joined by @EmDimitrakakis, CEO of Panda Surgical to discuss their incredible innovative work developing handheld robots for minimally invasive #neurosurgery

@DrWalterJean Excited to see!

NEW BOOK! The "keyhole" concept is 30 years old, and we are excited to be part of the MIS movement, if you can still call it that. A lot of sweat went into this from my co-editors and I owe them, and the staff at Thieme, my gratitude. To all the contributors, "thank you" as well, and I hope everyone enjoys the book. You can find it on Amazon and shop.thieme.com/Video-Atlas-of… @KunalVakhariaMD

How do you feel about robots in neurosurgery? Our team at Queen Square, led by @hani_marcus is running a short survey to understand patient and public views on robotic technology in minimally invasive neurosurgery! 🧠 Open to patients & the public docs.google.com/forms/d/e/1FAI…

6th June: Neuro-Oncology Course Info & Registration: rb.gy/j40j2c Join us at the Queen Square Simulation Centre for a hands-on neuro-oncology course focused on the practical use of modern surgical adjuncts in brain tumour surgery. This one-day course is designed to give trainees meaningful hands-on exposure to technologies that increasingly shape day-to-day neuro-oncological practice. The course is built around small-group, station-based simulation sessions covering 5-ALA–guided tumour resection, intraoperative ultrasound, intraoperative neuromonitoring, diffusion tensor imaging, and minimally invasive approaches. Emphasis is placed on how these tools are used in real operative workflows, how to interpret the information they provide, and how they influence intraoperative decision-making. All practical sessions are delivered with close faculty supervision, allowing time for hands-on practice, discussion, and feedback in a high-fidelity simulation environment. The course is aimed at mid- to senior-level trainees looking to consolidate their understanding of contemporary neuro-oncology techniques and translate them safely into clinical practice.

We are always delighted to host residents from @ColumbiaNeuro at Queen Square – they’re consistently brilliant.

I’ll be answering your questions live for UCL Brain Sciences: I’m a brain surgeon – ask me anything Students, patients, curious minds welcome. Join us 👇 ucl.ac.uk/brain-sciences…

AI is cool and all... but a new paper in @ScienceMagazine kind of figured out the origin of life? The paper reports the discovery of a simple 45-nucleotide RNA molecule that can perfectly copy itself.

We’ve shifted our afternoon session from theory to practice, diving into immersive simulation at Queen Square. We’ll be doing hands-on rotations through retrosigmoid, translabyrinthine and middle fossa approaches, all while discussing cases in VR. Excellent opportunity to translate anatomical knowledge into surgical strategy in a safe, high-fidelity environment. 🧠🔬

@DoctorZada @USCBTC Great work, @DoctorZada!

New publication from the @USCBTC in Operative Neurosurgery. Intraoperative tumor consistency grading helps guide resection strategy for Pituitary Tumors (PitNETs), supporting preferential extracapsular resection for firm tumors. #Pituitary #Neurosurgery #OperativeNeurosurgery #PitNET #EndoscopicSkullBase @NeurosurgeryUSC @KECKSchool_USC @KeckMedicineUSC Link: doi.org/10.1227/ons.00…

This week Dr Feras Fayez takes us through his work on surgical simulation and its crucial role in training the next generation of surgeons - and our work developing high-fidelity models and AI-enabled training solutions #neurosurgery #simulation

2026 is a decade since I filed this patent on June 2016. The NANT Cancer Vaccine (The Cancer BioShield Platform) is now in full scale development at @ImmunityBio. Finally, the drive to memory NK and T cells for long-term survival is being proven. This figure is another representation of the drawing in 2016 of my mind map since 1990.

Incredible early results for a (still) devastating disease
