Biochemistry Researchers Repair and Regenerate Heart Muscle Cells

Posted by in categories: biotech/medical, chemistry, life extension, mathematics

Researchers at the University of Houston are reporting a first-of-its-kind technology that not only repairs heart muscle cells in mice but also regenerates them following a heart attack, or myocardial infarction as its medically known.

Published in The Journal of Cardiovascular Aging 0, the groundbreaking finding has the potential to become a powerful clinical strategy for treating heart disease in humans, according to Robert Schwartz, Hugh Roy and Lillie Cranz Cullen Distinguished Professor of biology and biochemistry at the UH College of Natural Sciences and Mathematics.

The new technology developed by the team of researchers uses synthetic messenger ribonucleic acid (mRNA) to deliver mutated transcription factors — proteins that control the conversion of DNA into RNA — to mouse hearts.

Unfortunately my internet link went down in the second Q&A session at the end and the recording cut off. Shame, loads of great information came out about FPGA/ASIC implementations, AI for the VR/AR, C/C++ and a whole load of other riveting and most interesting techie stuff. But thankfully the main part of the talk was recorded.

Researcher uses math to investigate possibility of time travel

Posted by in categories: cosmology, education, mathematics, physics, time travel

After some serious number crunching, a UBC researcher has come up with a mathematical model for a viable time machine.

Ben Tippett, a mathematics and physics instructor at UBC’s Okanagan campus, recently published a study about the feasibility of . Tippett, whose field of expertise is Einstein’s theory of general relativity, studies black holes and science fiction when he’s not teaching. Using math and physics, he has created a formula that describes a method for time travel.

“People think of time travel as something as fiction,” says Tippett. “And we tend to think it’s not possible because we don’t actually do it. But, mathematically, it is possible.”

New device gets scientists closer to quantum materials breakthrough

Posted by in categories: computing, mathematics, quantum physics

Researchers from the University of Nebraska-Lincoln and the University of California, Berkeley, have developed a new photonic device that could get scientists closer to the “holy grail” of finding the global minimum of mathematical formulations at room temperature. Finding that illusive mathematical value would be a major advancement in opening new options for simulations involving quantum materials.

Many scientific questions depend heavily on being able to find that mathematical value, said Wei Bao, Nebraska assistant professor of electrical and computer engineering. The search can be challenging even for modern computers, especially when the dimensions of the parameters—commonly used in quantum physics—are extremely large.

Until now, researchers could only do this with polariton optimization devices at extremely low temperatures, close to about minus 270 degrees Celsius. Bao said the Nebraska-UC Berkeley team “has found a way to combine the advantages of light and matter at suitable for this great optimization challenge.”

Google wants to challenge AI with 200 tasks to replace the Turing test

Posted by in categories: mathematics, robotics/AI

Alan Turing first proposed a test for machine intelligence in 1950, but now researchers at Google and their partners have created a suite of 204 tests to replace it, covering subjects such as mathematics, linguistics and chess.

Found: A Quadrillion Ways for String Theory to Make Our Universe

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

Circa 2019


According to string theory, all particles and fundamental forces arise from the vibrational states of tiny strings. For mathematical consistency, these strings vibrate in 10-dimensional spacetime. And for consistency with our familiar everyday experience of the universe, with three spatial dimensions and the dimension of time, the additional six dimensions are “compactified” so as to be undetectable.

Different compactifications lead to different solutions. In string theory, a “solution” implies a vacuum of spacetime that is governed by Einstein’s theory of gravity coupled to a quantum field theory. Each solution describes a unique universe, with its own set of particles, fundamental forces and other such defining properties.

What Is Time? | Professor Sean Carroll explains the theories of Presentism and Eternalism

Posted by in categories: mathematics, physics

It’s said that the clock is always ticking, but there’s a chance that it isn’t. The theory of “presentism” states that the current moment is the only thing that’s real, while “eternalism” is the belief that all existence in time is equally real. Find out if the future is really out there and predictable—just don’t tell us who wins the big game next year.

This video is episode two from the series “Mysteries of Modern Physics: Time”, Presented by Sean Carroll.

Scientists Discover New Molecule That Kills Hard-to-Treat Cancers

Posted by in categories: biotech/medical, mathematics

A new molecule synthesized by a University of Texas at Dallas researcher kills a broad spectrum of hard-to-treat cancers, including triple-negative breast cancer, by exploiting a weakness in cells not previously targeted by other drugs.

A study describing the research — which was carried out in isolated cells, in human cancer tissue and in human cancers grown in mice — was published online June 2 in the journal Nature Cancer.

Dr. Jung-Mo Ahn, a co-corresponding author of the study and a UT Dallas associate professor of chemistry and biochemistry in the School of Natural Sciences and Mathematics, has been passionate about his work designing small molecules that target protein-protein interactions in cells for over a decade. Using an approach called structure-based rational drug design, he previously developed potential therapeutic candidate compounds for treatment-resistant breast cancer and for prostate cancer.
