Samsung’s Quantum Dot TV Tech to Find Medical Applications

Posted by in categories: bioengineering, chemistry, electronics, food, nanotechnology, quantum physics

Samsung get into the cancer treatment space with their own Q-Dot technology? Another reason for the FDA to show up in tech’s backyard; lookout for all those future federal and state regs & compliance training that will be coming that eats up 20 hours each month of your scientists and engineering talent’s time.


For a lot of users, Samsung might be known best for their smartphones and other mobile devices, but the company is so much more than that. Many of you reading this might have one of Samsung’s Super HD TV sets, a curved Samsung TV or some other model of theirs. Next to smartphones one of their more popular consumer electronics is of course of TVs, and with the advent of new technology such as Quantum Dot, Samsung is getting even better at producing a great image. One area that you might expect to find this Quantum Dot technology being used is for medical uses, but that’s just what researchers have been exploring recently.

Explaining a Quantum Dot can become quite tricky, but to cut a long story short, they are semiconductors that are so small they register at the nanoscale side of things. In terms of Quantum Dots used in television displays, it’s their ability to precisely tune to a specific and exact part of the color spectrum that makes them so attractive, not to mention their much lower power draw. Now, Kim Sung-jee, a professor of the Chemistry department at Pohang University of Science and Technology (POSTECH), has said that “when combining protein which clings to cancer cells and quantum dots, it can be used to seek out cancer cells in the body”. It’s reasoned that the potential for these Quantum Dots to be so precise in terms of color reproduction can help physicians track down certain cancer cells.

Discovery of a fundamental limit to the evolution of the genetic code

Posted by in categories: bioengineering, biotech/medical, evolution, genetics

A study performed at IRB Barcelona offers an explanation as to why the genetic code stopped growing 3,000 million years ago. This is attributed to the structure of transfer RNAs—the key molecules in the translation of genes into proteins. The genetic code is limited to 20 amino acids—the building blocks of proteins—the maximum number that prevents systematic mutations, which are fatal for life. The discovery could have applications in synthetic biology.

Nature is constantly evolving—its limits determined only by variations that threaten the viability of species. Research into the origin and expansion of the are fundamental to explain the evolution of life. In Science Advances, a team of biologists specialised in this field explain a limitation that put the brakes on the further development of the genetic code, which is the universal set of rules that all organisms on Earth use to translate genetic sequences of nucleic acids (DNA and RNA) into the that comprise the proteins that undertake cell functions.

Headed by ICREA researcher Lluís Ribas de Pouplana at the Institute for Research in Biomedicine (IRB Barcelona) and in collaboration with Fyodor A. Kondrashov, at the Centre for Genomic Regulation (CRG) and Modesto Orozco, from IRB Barcelona, the team of scientists has demonstrated that the genetic code evolved to include a maximum of 20 and that it was unable to grow further because of a functional limitation of transfer RNAs—the molecules that serve as interpreters between the language of genes and that of proteins. This halt in the increase in the complexity of life happened more than 3,000 million years ago, before the separate evolution of bacteria, eukaryotes and archaebacteria, as all organisms use the same code to produce proteins from genetic information.

Scientists turn skin cells into heart and brain cells using only drugs — no stem cells required

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

Neurons created from chemically induced neural stem cells. The cells were created from skin cells that were reprogrammed into neural stem cells using a cocktail of only nine chemicals. This is the first time cellular reprogramming has been accomplished without adding external genes to the cells. (credit: Mingliang Zhang, PhD, Gladstone Institutes)

Scientists at the Gladstone Institutes have used chemicals to transform skin cells into heart cells and brain cells, instead of adding external genes — making this accomplishment a breakthrough, according to the scientists.

DARPA Exhibit to Open at Chicago’s Museum of Science and Industry

Posted by in categories: bioengineering, biological, chemistry, science

Now, that’s an exhibit!


May 5, 2016, will mark the opening of a new and exciting exhibit at Chicago’s famed Museum of Science and Industry: an in-depth and interactive look behind the curtain at the Defense Advanced Research Projects Agency (DARPA).

DARPA was created in 1958 at the peak of the Cold War in response to the Soviet Union’s launch of Sputnik, the world’s first manmade satellite, which passed menacingly over the United States every 96 minutes. Tasked with preventing such strategic surprises in the future, the agency has achieved its mission over the years in part by creating a series of technological surprises of its own, many of which are highlighted in the Chicago exhibit, “Redefining Possible.”

“We are grateful to Chicago’s Museum of Science and Industry for inviting us to tell the DARPA story of ambitious problem solving and technological innovation,” said DARPA Deputy Director Steve Walker, who will be on hand for the exhibit’s opening day. “Learning how DARPA has tackled some of the most daunting scientific and engineering challenges—and how it has tolerated the risk of failure in order to have major impact when it succeeds—can be enormously inspiring to students. And for adults, we hope the exhibit will serve as a reminder that some of the most exciting work going on today in fields as diverse as chemistry, engineering, cyber defense and synthetic biology are happening with federal support, in furtherance of pressing national priorities.”

Researchers Identify Potential HIV Vaccine Possibility With ‘Looped’ Antibodies

Posted by in categories: bioengineering, biotech/medical, computing

Scientists are now one step closer to neutralizing HIV.

In a study conducted at Vanderbilt University and published in Proceedings of the National Academy of Sciences, researchers isolated antibodies with a loop-like structure that binds tightly to HIV and disables it. Unlike traditional vaccines, which jump-start an immune response by exposing the patient to a pathogen, this newly discovered method could work even in people who have not previously been exposed to by the virus.

Using computer modeling, the researchers identified the amino acid sequences that bound most tightly to HIV and re-engineered them in an optimal sequence that simulated vaccination.

Math points to 100-times faster mapping of gene activity

Posted by in categories: bioengineering, biotech/medical, chemistry, mathematics

New research by UCSF scientists could accelerate – by 10 to 100-fold – the pace of many efforts to profile gene activity, ranging from basic research into how to build new tissues from stem cells to clinical efforts to detect cancer or auto-immune diseases by profiling single cells in a tiny drop of blood.

The study, published online April 27, 2016, in the journal Cell Systems, rigorously demonstrates how to extract high-quality information about the patterns of in individual cells without using expensive and time-consuming technology. The paper’s senior authors are Hana El-Samad, PhD, an associate professor of biochemistry and biophysics at UCSF, and Matt Thomson, PhD, a faculty fellow in UCSF’s Center for Systems and Synthetic Biology.

“We believe the implications are huge because of the fundamental tradeoff between depth of sequencing and throughput, or cost,” said El-Samad. “For example, suddenly, one can think of profiling a whole tumor at the single cell level.”

Gene Editing Made Easier, Thanks to Carbon Nanotubes

Posted by in categories: bioengineering, biotech/medical, genetics, nanotechnology

In a new study, researchers detail the culturing and transfecting of cells with genetic material on an array of carbon nanotubes, which appears to overcome the limitations of other gene editing technologies.

Gene editing techniques hold great promise. They allow targeted and specific edits of genes, and have nearly limitless possibilities in the field of medicine.

Which is not to say that they are perfect. These techniques still have a range of limitations, from precision to toxicity. But a new study shows that can be changed.
