Technology Platform

Posted by in categories: 3D printing, biological, bioprinting, cyborgs

Kyle Reese: The Terminator’s an infiltration unit, part man, part machine. Underneath, it’s a hyperalloy combat chassis — micro processor-controlled, fully armored. Very tough. But outside, it’s living human tissue — flesh, skin, hair, blood, grown for the cyborgs…


3D bioprinting is the automated fabrication of multicellular tissue via spatially defined deposition of cells. The ability to spatially control deposition in the x, y and z axes allows for creation of tissue-specific patterns or compartments, with in vivo-like architecture that mimics key aspects of native biology.

3D bioprinted tissues exhibit a microenvironment more suited to in vivo-like cellular function in comparison to traditional 2D monoculture (or monolayer co-cultures), as well as maintenance of a more defined architecture than is observed in self-aggregated co-culture models.

Neuroscience shows that 50-year-olds can have the brains of 25-year-olds if they sit quietly and do nothing for 15 minutes a day

Posted by in category: neuroscience

Neuroscientist Sara Lazar, of Mass General and Harvard Medical School, started studying meditation by accident. She sustained running injuries training for the Boston Marathon, and her physical therapist told her to stretch. So Lazar took up yoga.

“The yoga teacher made all sorts of claims, that yoga would increase your compassion and open your heart,” said Lazar. “And I’d think, ‘Yeah, yeah, yeah, I’m here to stretch.’ But I started noticing that I was calmer. I was better able to handle more difficult situations. I was more compassionate and open hearted, and able to see things from others’ points of view.”

Eventually, she looked up the scientific literature on mindfulness meditation (a category into which yoga can fall). She found the ever-increasing body of evidence that shows that meditation decreases stress, depression, and anxiety, reduces pain and insomnia, and increases quality of life.

All fields of the standard model and gravity are unified as an E8 principal bundle connection

Posted by in category: particle physics

A non-compact real form of the E8 Lie algebra has G2 and F4 subalgebras which break down to strong su, electroweak su x u, gravitational so(3,1), the frame-Higgs, and three generations of fermions related by triality. The interactions and dynamics of these 1-form and Grassmann valued parts of an E8 superconnection are described by the curvature and action over a four dimensional base manifold.

Scientists Reverse The Age of White Blood Cells In A Female Human Being – They’re Now 20 Years Younger

Posted by in categories: biotech/medical, life extension, neuroscience

Elizabeth Parris, the CEO of Bioviva USA Inc, has become the very first human being to successfully, from a biological standpoint, reverse the age of her white blood cells, thanks to her own company’s experimental therapies. Bioviva utilizes intramural and extramural peer-reviewed research to create therapies for age-related diseases (Parkinson’s, Alzheimer’s, cancer, heart-disease), and now, they have reversed 20 years of ‘telomere shortening’ in a human for the first time.

Telomeres are short segments of DNA that cap the ends of every chromosome and act as a protective feature against wear and tear, which occurs naturally as the human body ages. As we age, these telomeres become shorter and shorter as our cells continue to divide more and more. Eventually they become too short to protect the chromosome, which is what causes our cells to malfunction and age related diseases to start setting in.

In September of last year, the 44 year old volunteered to partake in two of her own company’s experimental gene therapies; one intended to battle stem cell depletion, which happens when we age and leads to various age related diseases, and the other intended to protect against loss of muscle mass with age.

Engineers design nanostructured diamond metalens for compact quantum technologies

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

At the chemical level, diamonds are no more than carbon atoms aligned in a precise, three-dimensional (3D) crystal lattice. However, even a seemingly flawless diamond contains defects: spots in that lattice where a carbon atom is missing or has been replaced by something else. Some of these defects are highly desirable; they trap individual electrons that can absorb or emit light, causing the various colors found in diamond gemstones and, more importantly, creating a platform for diverse quantum technologies for advanced computing, secure communication and precision sensing.

Quantum technologies are based on units of quantum information known as “qubits.” The spin of electrons are prime candidates to serve as qubits; unlike binary computing systems where data takes the form of only 0s or 1s, electron spin can represent information as 0, 1, or both simultaneously in a quantum superposition. Qubits from are of particular interest to quantum scientists because their quantum-mechanical properties, including superposition, exist at room temperature, unlike many other potential quantum resources.

The practical challenge of collecting information from a single atom deep inside a crystal is a daunting one, however. Penn Engineers addressed this problem in a recent study in which they devised a way to pattern the surface of a diamond that makes it easier to collect light from the defects inside. Called a metalens, this contains nanoscale features that bend and focus the light emitted by the defects, despite being effectively flat.

When Will Quantum Computers Outperform Regular Computers?

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

Any day now, quantum computers will solve a problem too hard for a classical computer to take on. Or at least, that’s what we’ve been hoping. Scientists and companies are racing toward this computing milestone, dubbed quantum supremacy and seemingly just beyond our reach, and if you’ve been following the quantum computing story, you might wonder why we’re not there yet, given all the hype.

The short answer is that controlling the quantum properties of particles is hard. And even if we could use them to compute, “quantum supremacy” is a misleading term. The first quantum supremacy demonstration will almost certainly be a contrived problem that won’t have a practical or consumer use. Nonetheless, it’s a crucial milestone when it comes to benchmarking these devices and establishing what they can actually do. So what’s holding us back from the future?

Russian Biologist Pledges to Create More CRISPR-Edited Babies

Posted by in category: biotech/medical

“I think I’m crazy enough to do it,” he told Nature.

Rebrikov plans to target CCR5, the same gene as He, which could theoretically make the babies immune to HIV. But experts say the risks and unknowns — including the possibility of premature death — vastly outweigh any potential benefits.

“The technology is not ready,” CRISPR-Cas9 co-inventor Jennifer Doudna told Nature of Rebrikov’s plans. “It is not surprising, but it is very disappointing and unsettling.”

Beewolves use a gas to preserve food

Posted by in category: food

Scientists from the Universities of Regensburg and Mainz and the Max Planck Institute for Chemical Ecology discovered that the eggs of the European beewolf produce nitric oxide. The gas prevents the larvae’s food from getting moldy in the warm and humid brood cells. The results were published in the journal eLife.

Food stored in warm and humid conditions gets moldy very quickly and thus becomes inedible or even toxic. To prevent this, we use refrigerators and freezers as well as various other methods of preservation. Animals do not have such technical appliances and therefore need to find other ways to preserve food. The European beewolf Philanthus triangulum, a solitary wasp species whose females hunt honey bees, has evolved a successful method of food preservation. A female takes up to five honey bees into its brood cells where they serve as food for a young beewolf. Female beewolves prefer to build their nests in sunlit and sandy places. The nests are deep and therefore the brood cells are warm and humid. Such conditions are favorable for the development of the beewolf larvae; however, they also foster the growth of mold fungi. As a matter of fact, bees stored under such conditions in the lab were overgrown by mold within one to three days.
