Google DeepMind discovers new solutions to century-old problems in fluid dynamics
For centuries, mathematicians have developed complex equations to describe the fundamental physics involved in fluid dynamics. These laws govern everything from the swirling vortex of a hurricane to airflow lifting an airplane’s wing.
Experts can carefully craft scenarios that make theory go against practice, leading to situations which could never physically happen. These situations, such as when quantities like velocity or pressure become infinite, are called ‘singularities’ or ‘blow ups’. They help mathematicians identify fundamental limitations in the equations of fluid dynamics, and help improve our understanding of how the physical world functions.
In a new paper, we introduce an entirely new family of mathematical blow ups to some of the most complex equations that describe fluid motion. We’re publishing this work in collaboration with mathematicians and geophysicists from institutions including Brown University, New York University and Stanford University.
Spider-inspired magnetic soft robots could perform minimally invasive gastrointestinal tract procedures
The gastrointestinal (GI) tract is a collection of organs and structures inside the bodies of humans and other animals that is responsible for the digestion of food, the absorption of nutrients and the expulsion of waste. Its underlying parts include the mouth, esophagus, stomach, intestines, rectum and anus.
Over the past decades, the incidence of cancer in the GI tract and some other conditions affecting the digestive system has risen substantially. Existing approaches to diagnose and treat GI cancers rely on endoscopy, a medical procedure that entails the inspection of internal organs via a flexible tube with an embedded camera (i.e., endoscope), which is inserted into the body through the anus, mouth or a small incision.
In addition to being highly uncomfortable for patients, endoscopy often fails to reach regions that are deep into the GI tract or are difficult to access due to the body’s natural configuration. Some biomedical engineers have thus been trying to devise alternative systems that could inspect parts of the digestive system more effectively, while causing patients minimal discomfort.
The looming crackdown on AI companionship
The risks posed when kids form bonds with chatbots have turned AI safety from an abstract worry into a political flashpoint. What happens now?
Are Cybernetic Organisms The Key To Exploring Space?! | NASA’s Unexplained Files
As NASA seeks to expand its exploration of the solar system, the concept of developing cybernetic organisms consists of a part human and part robot design. This idea holds the potential to enhance space exploration by overcoming various limitations.

Rhythmic yoga breathing produces measurable brain activity linked to deep relaxation
Researchers at the Indian Institute of Technology Gandhinagar, in collaboration with Sri Sri Institute of Advanced Research and Fortis Escort Heart Institute, report that rhythmic breathing in Sudarshan Kriya Yoga (SKY) produces measurable shifts in brain rhythms associated with deep relaxation. The team finds that SKY practice increases theta and delta brain activity while reducing alpha power.
Rising rates of stress, anxiety, and depression combined with limited access to professional care have created a desire for low-cost, self-managed approaches to mental health.
Previous investigations into yoga, meditation, and breathing exercises have documented improvements in mood, fatigue, emotional processing, and executive brain functions. Meditation practices have been linked to structural and functional changes in neural networks governing attention, self-referential processing, and emotion regulation.
