Twisting Light Unlocks New Quantum Realms

Posted by in categories: computing, mathematics, particle physics, quantum physics

A research team is studying how light moves through special circuits called optical waveguides, using a concept called topology. They’ve made an important discovery that combines stable light paths with light particle interactions, which could make quantum computers more reliable and lead to new technological advancements.

Scientific innovation often arises as synthesis from seemingly unrelated concepts. For instance, the reciprocity of electricity and magnetism paved the way for Maxwell’s theory of light, which, up until now, is continually being refined and extended with ideas from quantum mechanics.

Similarly, the research group of Professor Alexander Szameit at the Institute of Physics at the University of Rostock explores light evolution in optical waveguide circuits in the presence of topology. This abstract mathematical concept was initially developed to classify solid geometries according to their global properties. Szameit explains: “In topological systems, light only follows the global characteristics of the waveguide system. Local perturbations to the waveguides such as defects, vacancies, and disorder cannot divert its path.”

Scientists Discover Unexpected Importance of “Time Cells” for Complex Learning

Posted by in categories: biotech/medical, health, neuroscience

Researchers at the University of Utah Health have discovered that “time cells” in mice are crucial for learning tasks where timing is critical. These cells change their firing patterns as mice learn to distinguish between timed events, suggesting a role beyond just measuring time. This finding could help in the early detection of neurodegenerative diseases like Alzheimer’s by highlighting the importance of the medial entorhinal cortex (MEC), which is among the first brain regions affected by such diseases.

Researchers at the University of Utah Health found that “time cells” in mice adapt to learning timed tasks, a discovery that could aid early Alzheimer’s detection by monitoring changes in a key brain region.

Our perception of time is crucial to our interaction with and understanding of the world around us. Whether we’re engaging in a conversation or driving a car, we need to remember and gauge the duration of events—a complex but largely unconscious calculation running constantly beneath the surface of our thoughts.

Researchers investigate the impacts of space travel on astronauts’ eye health

Posted by in categories: biotech/medical, health

As space travel becomes more common, it is important to consider the impacts of space flight and altered gravity on the human body. Led by Dr. Ana Diaz Artiles, researchers at Texas A&M University are studying some of those impacts, specifically effects on the eye. The findings are published in the journal npj Microgravity.

Could we recycle plastic bags into fabrics of the future?

Posted by in categories: sustainability, wearables

The only problem with plastic profusion is that “recycling” it is at a “caveman’s” level!


In considering materials that could become the fabrics of the future, scientists have largely dismissed one widely available option: polyethylene.

The stuff of plastic wrap and grocery bags, polyethylene is thin and lightweight, and could keep you cooler than most textiles because it lets heat through rather than trapping it in. But polyethylene would also lock in water and sweat, as it’s unable to draw away and evaporate moisture. This antiwicking property has been a major deterrent to polyethylene’s adoption as a wearable .

The event is so rare because of its large size – 375 meters (1230 feet) average diameter – as well as its proximity to the Earth.

“The 2029 flyby is an incredibly rare event,” ESA explained in an X post. “By comparing impact craters across the Solar System with the sizes and orbits of all known asteroids, scientists believe that an asteroid as large as Apophis only comes this close to Earth once every 5,000 to 10,000 years.

Mathematicians Accidentally Found a New Way to Represent Pi

Posted by in categories: mathematics, particle physics, quantum physics

Our favorite mathematical constant, pi (π), describing the ratio between a circle’s circumference and its diameter, has taken on new meaning.

The new representation was borne out of the twists and turns of string theory, and two mathematicians’ attempts to better describe particle collisions.

“Our efforts, initially, were never to find a way to look at pi,” says Aninda Sinha of the Indian Institute of Science (IISc) who co-authored the new work with fellow IISc mathematician Arnab Priya Saha.
