Growing Old Could Have Played a Critical Role in Our Evolution

Posted by in categories: biological, computing, life extension

Growing old may come with more aches and pains attached, but new research suggests there’s a bigger picture to look at: by reaching our dotage, we might actually be helping the evolution of our species.

Once assumed to be an inevitable consequence of living in a rough-and-tumble world, aging is now considered something of a mystery. Some species barely age at all, for example. One of the big questions is whether aging is simply a by-product of biology, or something that comes with an evolutionary advantage.

The new research is based on a computer model developed by a team from the HUN-REN Centre for Ecological Research in Hungary which suggests old age can be positively selected for in the same way as other traits.

Alex Rosenberg: Scientism, Naturalism, and Conscious Thought

Posted by in categories: biological, neuroscience

In this episode of the Smarter Not Harder Podcast, our guest Alex Rosenberg joins our host Boomer Anderson to give one-cent solutions to life’s $64,000 questions that include:\
What are the definitions of scientism and naturalism?\
Is there such a thing as free will, and if so, what implications does it have on the search for purpose in life?\
What is nice nihilism?\
Alex Rosenberg is an American philosopher and novelist. He is the R. Taylor Cole Professor of Philosophy at Duke University, and is well known for contributions in the philosophy of biology, as well as the philosophy of economics. He has also written several books, including \.

Ancient Insect Mysteries Solved: 312-Million-Year-Old Fossil Sheds Light on Behavior and Evolution

Posted by in categories: biological, evolution

Prehistoric insects, with their delicate and soft bodies, are challenging to preserve as fossils. While wings are more commonly fossilized, the bodies of these insects are often fragmented or incomplete, posing difficulties for scientific study. Paleontologists often rely on trace fossils to learn about these ancient insects, which are almost exclusively found as traces on fossil plants.

“We have a great fossil plant record,” said Richard J. Knecht, a Ph.D. candidate in the Department of Organismic and Evolutionary Biology at Harvard. “Further back in time, it’s the trace fossils that tell us more about the evolution and behavior of insects than the body fossils because plants and the trace fossils on them preserve very well. And the trace, as opposed to a body, won’t move over time and is always found where it was made.”

World’s first human brain-scale neuromorphic supercomputer is coming

Posted by in categories: biological, mathematics, robotics/AI, supercomputing

ICYMI: DeepSouth uses a #neuromorphiccomputing system which mimics biological processes, using hardware to efficiently emulate large networks of spiking #neurons at 228 trillion #Synaptic operations per second — rivalling the estimated rate of operations in the human brain.

Australian researchers are putting together a supercomputer designed to emulate the world’s most efficient learning machine – a neuromorphic monster capable of the same estimated 228 trillion synaptic operations per second that human brains handle.

As the age of AI dawns upon us, it’s clear that this wild technological leap is one of the most significant in the planet’s history, and will very soon be deeply embedded in every part of our lives. But it all relies on absolutely gargantuan amounts of computing power. Indeed, on current trends, the AI servers NVIDIA sells alone will likely be consuming more energy annually than many small countries. In a world desperately trying to decarbonize, that kind of energy load is a massive drag.

Embedding nanodiamonds in polymer can advance quantum computing and biological studies

Posted by in categories: biological, computing, nanotechnology, particle physics, quantum physics

A nitrogen-vacancy (NV) center is a defect in the crystal structure of diamond, where a nitrogen atom replaces a carbon atom in the diamond lattice and a neighboring site in the lattice is vacant. This and other fluorescent defects in diamond, known as color centers, have attracted researchers’ attention owing to their quantum properties, such as single-photon emission at room temperature and with long coherence time. Their many applications include quantum information encoding and processing, and cell marking in biological studies.

Microfabrication in diamond is technically difficult, and nanodiamonds with color centers have been embedded in custom-designed structures as a way of integrating these quantum emitters into photonic devices. A study conducted at the University of São Paulo’s São Carlos Institute of Physics (IFSC-USP) in Brazil has established a method for this, as described in an article published in the journal Nanomaterials.

“We demonstrated a method of embedding fluorescent nanodiamonds in designed for this purpose, using two-photon polymerization [2PP],” Cleber Mendonça, a professor at IFSC-USP and last author of the article, told Agência FAPESP. “We studied the ideal concentration of nanodiamond in the photoresist to achieve structures with at least one fluorescent NV center and good structural and optical quality.” The photoresist is a light-sensitive material used in the fabrication process to transfer nanoscale patterns to the substrate.

Unexpected Discovery About the Body’s Temperature Sensors Could Lead To Better Pain Relievers

Posted by in categories: biological, electronics

The ability to accurately detect heat and pain is critical to human survival. However, the molecular mechanisms behind how our bodies identify these dangers have long been a mystery to scientists.

Now, University at Buffalo researchers have unraveled the complex biological phenomena that drive these critical functions. Their research, recently published in the Proceedings of the National Academy of Sciences, has uncovered a previously unknown and completely unexpected “suicidal” reaction in ion channel receptors that explains the complicated mechanisms that underlie sensitivity to temperature and pain.

The research could be applied to the development of more effective pain relievers.

The Science of Looking Younger, Longer

Posted by in categories: biological, life extension, science

In Episode 6 of the Lifespan podcast, Dr. David Sinclair and co-host Matthew LaPlante discuss cosmetic aging and how to improve skin, nails, and hair. They talk about why superficial aging occurs and how external signs of aging are often a reflection of biological age. The latest science behind various beautifying therapies is highlighted, including newer interventions like low-level laser therapy and platelet-rich plasma injections. #DavidSinclair #Longevity #SkinCare T.
