You might have heard that according to Einstein’s theories of special and general relativity time doesn’t pass for light, or that time actually stops for light. Can this possibly be correct? In this video, I will look at what the maths says and discuss what it means.

Scientists Solve Decades-Old Microscopy Problem

Posted by in categories: biotech/medical, innovation

Studying tissues, cells, and proteins under a microscope is essential for disease prevention and treatment. This research requires accurately measuring the dimensions of these biological structures. However, when viewed through a light microscope, these samples can sometimes appear more flattened than their true form.

Researchers at Delft University of Technology have now demonstrated for the first time that this distortion is not constant, contrary to what many scientists have assumed for decades. The breakthrough, published in Optica, confirms a prediction by Nobel laureate Stefan Hell from the 90s. With an online calculation tool and software, every researcher can now determine the correct depth of a biological sample.

Ghost Particles: Neutrinos Challenge Everything We Know About Physics

Posted by in category: particle physics

The discovery and ongoing research into neutrinos have significantly altered the foundational concepts of particle physics, highlighting the particles’ mass and challenging the accuracy of the standard model.

In the 1930s, it turned out that neither the energy nor the momentum balance is correct in the radioactive beta decay of an atomic nucleus. This led to the postulate of “ghost particles” that “secretly” carry away energy and momentum. In 1956, experimental proof of such neutrinos was finally obtained.

The challenge: neutrinos only interact with other particles of matter via the weak interaction that is also underlying the beta decay of an atomic nucleus. For this reason, hundreds of trillions of neutrinos from the cosmos, especially the sun, can pass through our bodies every second without causing any damage. Extremely rare neutrino collisions with other particles of matter can only be detected with huge detectors.

Taste Buds Meet Technology: AI’s Impact on Personalized Taste Experiences

Posted by in categories: food, robotics/AI

The recent collaboration between Kaffa Roastery and Elev highlights the potential of AI in food science, particularly in creating personalized taste experiences.

Taste Buds Meet TechnologyThe recent collaboration between Kaffa Roastery and Elev, a Finnish AI consultancy, has shed light on the potential of artificial intelligence in the world of food science. By leveraging AI models to create a unique coffee blend tailored to enthusiasts’ tastes, this partnership has opened up a new realm of possibilities for personalized food experiences. But what if AI could go beyond just coffee blends? Imagine a future where AI can help individuals discover their unique taste profiles and create recipes specifically designed for their palates. This new approach to cooking could transform the way we think about food and our relationship with it.

Artificial Cells Built with Programmable Peptide-DNA Cytoskeletons

Posted by in categories: bioengineering, biotech/medical, life extension, nanotechnology

Unlike the rigid skeletons within our bodies, the skeletons within individual cells—cytoskeletons—are changeable, even fluid. And when these cytoskeletons reorganize themselves, they do more than support different cell shapes. They permit different functions.

Little wonder, then, that scientists who build artificial cells hope to create synthetic cytoskeletons that act like natural cytoskeletons. Synthetic cytoskeletons capable of supporting dynamic changes in cell shape and function could enable the development of novel drug delivery systems, diagnostic tools, and regenerative medicine applications.

Synthetic cytoskeletons have incorporated building blocks such as polymers, small molecules, carbon nanotubes, peptides, and DNA nanofilaments. Mostly DNA nanofilaments. Although they offer programmability, they can be hard to fine tune. To get around this difficulty, scientists based at UNC Chapel Hill led by Ronit Freeman, PhD, investigated the relatively unexplored possibilities offered by peptides. Specifically, the scientists engineered artificial cells using a programmable peptide–DNA nanotechnology approach.

Traditional Japanese Diet associated with Less Brain Shrinkage in Women compared to Western Diet, says research

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

Cognitive decline and dementia already affect more than 55 million people worldwide. This number is projected to skyrocket over the next few decades as the global population ages.

There are certain risk factors of cognitive decline and dementia that we cannot change – such as having a genetic predisposition to these conditions. But other risk factors we may have more power over – with research showing certain modifiable lifestyle habits, such as smoking, obesity and lack of exercise, are all linked to higher risk of dementia.

What role nutrition plays in preventing cognitive decline and dementia has also been the focus of scientific research for quite some time.

Inexplicable Flying Fox found in Hydra Galaxy Cluster

Posted by in category: space

High sensitivity radio observations have discovered a cloud of magnetized plasma in the Hydra galaxy cluster. The odd location and shape of this plasma defy all conventional explanations. Dubbed the Flying Fox based on its silhouette, this plasma will remain a mystery until additional observations can provide more insight.

A team led by Kohei Kurahara at the National Astronomical Observatory of Japan analyzed observations from the Giant Metrewave Radio Telescope (GMRT) targeting the Hydra galaxy cluster, located over 100 million light years away in the direction of the constellation Hydra.

By applying recent analysis techniques to the GMRT (Giant Metrewave Radio Telescope) data archive, the team was able to discover a cloud of magnetized plasma shaped like a flying fox which has never been reported before.

Chipless Fiber for Wireless Visual-to-Digital Transmission Senses Interactions with the Human Body

Posted by in categories: biotech/medical, computing

A team of materials scientists and engineers from Donghua University, in China, and the National University of Singapore, has developed a type of fiber that does not rely on chips or batteries to convert visual signals to digital transmissions as it interacts with the human body.

The paper is published in the journal Science. Yunzhu Li and Yiyue Luo with the University of Illinois Urbana-Champaign and MIT, respectively, have published a Perspective piece in the same journal issue outlining the work done by the team on this new effort.

Over the past several years, scientists have been trying to find a way to integrate electronic devices with textiles for such applications as clothes that can display colors, patterns or even messages. Unfortunately, previous efforts involve adding stiff batteries and chips to materials, making them too uncomfortable to wear. In this new effort, the researchers have found a way to get around these problems.
