We showcase the Proto infinity wall, the Proto Epic, and the Proto M. Watch and enjoy, or else.
None of this happens without the entire team at Proto. The Protopians are made up of world class engineers, salespeople, resellers, investors, producers, developers, and partners. Without them, Proto is just a good idea. They’re the people who actually make these innovations happen.

University of Virginia scientists have identified a promising approach to delay aging by detoxifying the body of glycerol and glyceraldehyde, harmful by-products of fat that naturally accumulate over time.
The new findings come from UVA researcher Eyleen Jorgelina O’Rourke, Ph.D., and her team, who are seeking to identify the mechanisms driving healthy aging and longevity. Their new work suggests a potential way to do so by reducing glycerol and glyceraldehyde’s health-draining effects.
“The discovery was unexpected. We went after a very well-supported hypothesis that the secret to longevity was the activation of a cell-rejuvenating process named autophagy and ended up finding an unrecognized mechanism of health and lifespan extension,” said O’Rourke, of UVA’s Department of Biology and the UVA School of Medicine’s Department of Cell Biology.
To check that atomic weapons work, scientists run simulations of explosions using high-energy lasers—and Russia is building the strongest one of all.
In vitro biological neural networks (BNNs) interconnected with robots, so-called BNN-based neurorobotic systems, can interact with the external world, so that they can present some preliminary intelligent behaviors, including learning, memory, robot control, etc.
This work aims to provide a comprehensive overview of the intelligent behaviors presented by the BNN-based neurorobotic systems, with a particular focus on those related to robot intelligence.
In this work, we first introduce the necessary biological background to understand the 2 characteristics of the BNNs: nonlinear computing capacity and network plasticity. Then, we describe the typical architecture of the BNN-based neurorobotic systems and outline the mainstream techniques to realize such an architecture from 2 aspects: from robots to BNNs and from BNNs to robots.
Researchers have completed the most advanced brain map to date, that of an insect, a landmark achievement in neuroscience that brings scientists closer to true understanding of the mechanism of thought.
“It’s been 50 years and this is the first brain connectome. It’s a flag in the sand that we can do this.” —
The international team led by Johns Hopkins University and the University of Cambridge produced a breathtakingly detailed diagram tracing every neural connection in the brain of a larval fruit fly, an archetypal scientific model with brains comparable to humans.
Recently is has become known that one should not take Metformin unless you have diabetes. But a combo test of Rapamycin and Metformin showed each removed each others side effects. So here we have another combo test showing the effect on stem cells in the gut.
In a new study published in Aging Cell, researchers have shown that two promising anti-aging agents, the antibiotic rapamycin and the anti-diabetic drug metformin, reverse aging in a population of intestinal stem cells [1].
Older people are more prone to gastrointestinal problems [2]. Moreover, aging is a major risk factor for various cancers, including colorectal cancer. Therefore, it is necessary to develop therapeutic approaches to rejuvenate the aging intestine.

A team of Rutgers scientists dedicated to pinpointing the primordial origins of metabolism—a set of core chemical reactions that first powered life on Earth—has identified part of a protein that could provide scientists clues to detecting planets on the verge of producing life.
The research, published in Science Advances, has important implications in the search for extraterrestrial life because it gives researchers a new clue to look for, said Vikas Nanda, a researcher at the Center for Advanced Biotechnology and Medicine (CABM) at Rutgers.
Based on laboratory studies, Rutgers scientists say one of the most likely chemical candidates that kickstarted life was a simple peptide with two nickel atoms they are calling “Nickelback” not because it has anything to do with the Canadian rock band, but because its backbone nitrogen atoms bond two critical nickel atoms. A peptide is a constituent of a protein made up of a few elemental building blocks known as amino acids.
A new paper in Nature Communications illuminates how a previously poorly understood enzyme works in the cell. Many diseases are tied to chronic cellular stress, and UMBC’s Aaron T. Smith and colleagues discovered that this enzyme plays an important role in the cellular stress response. Better understanding how this enzyme functions and is controlled could lead to the discovery of new therapeutic targets for these diseases.
The enzyme is named ATE1, and it belongs to a family of enzymes called arginyl-tRNA transferases. These enzymes add arginine (an amino acid) to proteins, which often flags the proteins for destruction in the cell. Destroying proteins that are misfolded, often as a result of cellular stress, is important to prevent those proteins from wreaking havoc with cellular function. An accumulation of malfunctioning proteins can cause serious problems in the body, leading to diseases like Alzheimer’s or cancer, so being able to get rid of these proteins efficiently is key to long-term health.
The new paper demonstrates that ATE1 binds to clusters of iron and sulfur ions, and that the enzyme’s activity increases two-to three-fold when it is bound to one of these iron-sulfur clusters. What’s more, when the researchers blocked cells’ ability to produce the clusters, ATE1 activity decreased dramatically. They also found that ATE1 is highly sensitive to oxygen, which they believe relates to its role in moderating the cell’s stress response through a process known as oxidative stress.
