Come learn what's happening at MIT.nano and share your ideas!Since opening our doors in 2018, MIT.nano has grown from an impressive but empty building to an active laboratory supporting research from more than 250 MIT PI laboratories drawn from nearly 50 MIT departments, labs, and centers and welcoming hundreds of trained users into our spaces. On April 17, the MIT.nano staff will share with the MIT community what's been accomplished—and what comes next—including:Recent equipment installations;Equipment and design projects underway to integrate even more capabilities;MIT.nano programming and seminars;Your questions, ideas, and feedback.Join us afterward for an ice cream social in the MIT.nano East Lobby!SPACE IS LIMITED — PLEASE RSVPCan't join us in person? This event will also be webcast. Email your questions ahead of time to mitnano@mit.edu so we can be sure to answer them!

Speaker: Egor Shelukhin (University of Montreal)Title: Non-orderability and the contact Hofer metricAbstract: We discuss a recent joint work with Jakob Hedicke which relates contact non-orderability, the existence of positive contractible loops in the contactomoprhism group, and shortening in the contact Hofer metric. Together with considerations of contact open books, this shows that contact boundaries one-stabilizations of Weinstein manifolds, including the standard tight S1 x S2, are non-orderable.

Colloquium on the Brain and Cognition with Ivan Soltesz, PhD, Stanford UniversityDate: Thursday, April 17, 2025Time: 4:00pmLocation: 46-3002, Singleton Auditorium (Third floor of MIT Building 46)Zoom: https://mit.zoom.us/j/91469352101Organization and Control of Hippocampal CircuitsWhen animals are in an off-line, non-locomotor behavioral state, neuronal activity in the hippocampus is thought to be largely disengaged from the present setting to enable cognitive mechanisms such as memory consolidation and planning. But how does the brain re-engage with the present surroundings during this behavioral state and permit access to current sensory information or promote new memory formation? I will present recent results that indicate that dentate spikes may support associative memory during non-locomotor behavior, extending the repertoire of cognitive processes beyond the classical “off-line” functions. In the second part of the talk, I will show new evidence that suggests that a rarely studied part of the hippocampus, the Fasciola cinereum, may play surprisingly significant roles as a novel site of seizure onset and target for interventions in temporal lobe epilepsy in both mice and humans.Ivan Soltesz Ph.D. is the James R. Doty Professor of Neurosurgery and Neurosciences at Stanford University School of Medicine. He established his laboratory at UC Irvine in 1995, where he served as department Chair from 2006 until his return to Stanford in 2015. He is interested in the nature of inhibition in the CNS. His lab employs experimental and theoretical techniques to explore the synaptic and cellular organization of GABAergic circuits in the hippocampus under normal and pathological conditions.

Recreational swims provide a fun and engaging way for children and parents to practice new skills, stay active, and enjoy quality time together in the pool with the MIT community.No Z Center (MIT Recreation - Zesiger Sports and Fitness Center) membership is required to participate.A parent or caregiver must accompany children in the water. Per Z Center policy, each adult may supervise up to two children at a time.Children must be at least 6 months old to join. If younger, they must be able to hold their head up comfortably. Registration is here. Only for MIT Spouses and Partners Connect members.
