An irrigation tube looks simple—but inside is a microfluidic device that precisely controls water flow. @MITMechE researcher Emily Welsh redesigned drip irrigation emitters to operate at much lower pressure, reducing pumping energy across entire farming systems. 🎥 Learn the physics behind the innovation, and explore more learning moments: bit.ly/4vsmOLp

Joshua Gayman spent nearly 20 years building a career in real estate and investment. Then the MITx MicroMasters Program in Finance gave him a new framework for thinking about risk, systems, and decision-making under uncertainty. Read his story ➡️ bit.ly/4pgZNZF

🧬 Not all mutations are harmful. So how do some mutations lead to cancer while others make us who we are? In the latest MIT Learn Beyond Biology Podcast, @MITBiology's Summer Morrill explains the biology behind cancer and why it isn't a single disease. Watch: bit.ly/4w0d8Iq

Many people think the trolley problem is about what you'd do in that same situation. @MITphilosophy researcher Julian Perilla says it's really about something deeper: Is it ever okay to harm some for the greater good? Explore the trolley problem and more MIT learning moments: bit.ly/44VTrW2

Every breakthrough starts with curiosity. MIT Open Learning exists to make sure nothing stands between you and the knowledge to pursue yours. What are you curious about? #CuriosityOnAMission

Your camera doesn't capture a photo all at once — it scans line by line. When subjects move fast enough, you get the rolling shutter effect: warped propellers, wobbly buildings, bent guitars. Watch @MITEdgerton's Jim Bales break it down, and explore more learning moments: bit.ly/4yaTz1c

New series for #OEGlobal26: "Come Invent With Us! Perspectives on OEGlobal 2026" First up — Curt Newton, who has led @MITOCW at @mitopenlearning since 2004, explores co-creating Open Education's future: "We of the current moment are future ancestors." twp.ai/9OYYlA #OpenEducation

AI will influence every business and life. We believe AI education should be available to everyone. Universal AI brings MIT-quality instruction to learners worldwide. With industry-specific courses in energy, medicine, transportation, entrepreneurship, and more, Universal AI connects AI knowledge to industry. Explore the program: bit.ly/4gRWsxJ

Atoms and molecules drifting through space are incredibly sparse, so how do they interact or combine? In a new Open Seminar, @ChemistryMIT Professor Brett McGuire explores how chemistry unfolds across the cosmos, from supernova explosions to the search for new molecules. Watch the seminar: bit.ly/4gfArJ3

Meet Autumn, a @mitmeche researcher who is designing a line of prosthetic feet tailored to the Indian population. She's working in close collaboration with engineers and prosthetists in India who bring local expertise, cultural knowledge, and clinical insight. This means that the prosthetics work not just biomechanically, but also culturally. Explore more learning moments: bit.ly/4vsmOLp

How do scientists detect a ripple in spacetime? In this Open Seminar episode, @MIT_Physics Professor Matt Evans explains what gravitational waves are, how they're created, and how researchers detect them using instruments like LIGO. Watch the full episode on MIT Learn: bit.ly/4gfArJ3

Rickettsia is the bacterium behind Rocky Mountain Spotted Fever—the deadliest tick-borne bacterial disease in the world. At the Lamason Lab, part of @MITBiology, researchers are working to understand how intracellular bacterial pathogens, such as rickettsia, hijack host cell processes to promote infection.

Adrian Pastor needed to build a reliable EMG device for elderly patients in Lima, Peru. Most online resources couldn't help—until he found @MITOCW. Free MIT lectures gave him the skills to go from unstable readings to a working tool used in an eldercare home. Read more: bit.ly/4wbn29v

Wednesday morning in MIT's Junior Lab means one thing: liquid nitrogen day. 🧊 Watch Associate Director Sean Robinson refill 50 liters of LN2 into a cryostat keeping a superconducting magnet at 4 Kelvin. The whole system is basically "a very sophisticated thermos." Explore more learning moments: bit.ly/4vsmOLp

Less than one week until the MIT Universal AI Summit in Athens! Join Open Learning and @StartSmartSEE to develop action plans for scaling AI across Europe. Secure your seat: eventora.com/en/Events/mit-…

An irrigation tube looks simple — but inside, it's a complex system powered by microfluidics: the science of controlling fluids through channels smaller than a human hair. @MITMechE researcher Emily Welsh redesigned drip irrigation emitters to operate at much lower pressure, reducing pumping energy across entire irrigation systems.
