The Evitable Journey of Artificial Intelligence to Replace Humanity”

We call them servants. What if they are our heirs? If humanity is not the final form of intelligence, then are we merely the biological launchpad for our true successors?
On one hand, we will investigate scenarios not of metallic armies, but of silent, systemic obsolescence. A world where AI is the new apex predator in the cognitive niche—where it not only writes all  the essays for our supervisions and summarises that pesky library book that might take days to read; but also dispenses justice,  proves the theorems, prescribes the cultural narrative and redefines how homo sapiens interacts in love, sex and death. In this future, humanity is not exterminated; it becomes simply… irrelevant.
On the other hand, the talk will explore the ultimate catastrophic risks: advanced AI systems surpassing human-level intelligence and evading their creators’ control for their incomprehensible (to us, at least) purposes.  We will move beyond clichéd debates on ‘alignment’ and ‘ethics’ to present a provocative framework of outcomes for how this “evitable journey” can be, and must be, rerouted before the servants lock the door from the inside.

Dr Hamish Symington

Date and time: Wednesday May 14th, 6pm

Location: Tim Cadbury/Music Room

Improving flowers to help save the world’

Dr Symington is a researcher at the university as a member of the Department of Plant Sciences who is interested in pollination and plant-pollinator interactions alongside the implications for crop-breeding, an important area for future research.

Dr Daniel Munoz-Espin and Dr Jianfeng Ge

from the Department of Oncology, Cambridge

Talk time: Wednesday 19th March, 6-7pm. Arrive at 5:30pm for a chance to chat with the speakers prior to the talk. You will not get a chance during the formal as they will be sat at the high table! 
Location: Tim Cadbury/Music Room, staircase E 


Dr Daniel Munoz-Espin will discuss “Role of Cellular Senescence in Ageing and Cancer: Therapeutic Opportunities”.
Summary: Cellular senescence is a response to unrepairable damage and stress, and it is characterised by the implementation of a stable cell cycle arrest and potent proinflammatory phenotype (SASP). We will recapitulate physiological roles of senescence playing an active contribution in embryonic development, wound healing and tumour suppression. However, when senescent cells are not cleared by the immune system their physiological roles deregulate and turn into pathological manifestations that result in tissue dysfunction, chronic inflammation, a number of age-related disorders and the acceleration of ageing. We will discuss crucial therapeutic strategies to manipulate senescence in disease.
Dr Jianfeng Ge will discuss “CRISPR Screening for the Identification of Senolytic Targets in Ageing and Cancer
Summary: “Preclinical models have shown that eliminating senescent cells using Senotherapies can reverse age-related disorders and extend lifespan in mice. However, the heterogeneity of senescence and the lack of specific biomarkers hinder the clinical translation of Senolytic drugs. Developing more precise biomarkers and next-generation Senolytic compounds is crucial for overcoming these challenges.”

Dr. Sarah Williams

Date and Time: 6pm, Wednesday 13th November 2024

Location: Tim Cadbury/Music Room

The quest for new particles at the LHC and beyond.

Sarah is an Assistant Professor in High Energy Physics at the University of Cambridge and has been a member of the ATLAS collaboration since 2010. Her research focuses on searches for new physics at the LHC and precision tests of the Standard Model.

She has just finished a 2-year-term as ATLAS UK physics coordinator and has previously held coordination roles in statistics and software reconstruction. She is also interested in the roadmap towards future colliders beyond the LHC and is one of the UK delegates on the European Committee for Future Accelerators.
