A 3D-printed swallowable robot could perform gastrointestinal procedures
Recent technological advances have opened new possibilities for the development of advanced medical devices, including tiny robots that can safely move inside the human body. Some of these systems could help to simplify complex medical procedures, including delicate surgeries and the targeted delivery of drugs to specific sites.
THE MINIMAX lab at University of Texas (UT) Austin specializes in the development of tiny robots for medical, environmental, and other applications. In a recent preprint paper on arXiv, researchers from this lab introduced a new 3Dprintable and magnetically steerable capsule robot that could potentially help to diagnose and treat some gastrointestinal (GI) conditions.
“My motivation for GI health monitoring is deeply personal,” Fangzhou Xia, director of the MINIMAX lab at UT Austin and senior author of the paper, told Medical Xpress. “In 2022, when I was a postdoc at MIT, I experienced a severe GI medical episode involving repeated gallstone-induced bile duct blockage that ultimately required gallbladder removal surgery.
Something strange is happening in the Milky Way’s magnetic field
A stunning new map of the Milky Way reveals a dramatic magnetic flip hiding in plain sight. Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, revealing surprising twists in how it flows through our galaxy.
For generations, scientists have studied the stars and planets to better understand how our galaxy works. Now, Dr. Jo-Anne Brown, PhD, is focused on charting something we cannot see at all: the Milky Way’s magnetic field.
“Without a magnetic field, the galaxy would collapse in on itself due to gravity,” says Brown, a professor in the Department of Physics and Astronomy at the University of Calgary.

New ‘negative light’ technology hides data transfers in plain sight
Engineers at UNSW Sydney and Monash have developed an innovative way of sending hidden information that’s hard to intercept. Using a phenomenon known as “negative luminescence,” the system works by making signals blend perfectly into the background of natural heat radiation, such as can be seen with a thermal camera.
To outside observers, it looks like no data is being sent at all. Only a receiver with the right equipment can pick up the hidden message.
Because the very act of communication is invisible, the method makes signals almost impossible to intercept or hack. That means it could one day offer a powerful new security tool for sensitive communications in fields like defense and finance.
Sric4 News #05: a Message to The Youth: be The Voice of Peace
While space agencies globally recognize space applications, diplomacy, and national prestige as core justifications for their work, they remain hesitant to embrace a critical concept: the urgent humanization of space, or the urgent expansion of civilization into space. Similarly, educational institutions have not yet integrated matters related to civilian space development into their curricula. Reviewing the Space Renaissance Manifesto provides a deeper understanding of why the “humanization of space” is essential for the future. The proposition of diverting military spending toward civilian space development is simple yet transformative: it would directly elevate human quality of life. Wars are the worst experience a human population can encounter, and today we are witnessing more military confrontations around the world than at any time since WWII, action is necessary. With this short letter, we are calling the youth to take action. Youth working, or aspiring to work, in the space domain, are welcome to join Space Renaissance International (SRI) and become part of our cause. The Towards the Young Generation Committee is dedicated to guiding the next generation and advocating for the expansion of humanity into the cosmos.
This year marks the IV SRI World Congress (SRIC4), a landmark online event held every five years to set strategic guidelines. For the first time, a dedicated Youth Session is being hosted. Please see the specific EHTOS Call for Papers. And submit your abstract. Be sure to flag the EHTOS checkbox: “I am under 35 years old, this abstract is for the EHTOS context”
As a young professional or student, you will receive a discount when joining SRI. By submitting an abstract to the SRI World Congress, you will automatically join the youth special session.
