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.”

New genetic tools to boost productivity

Posted by in categories: biotech/medical, food, genetics

There’s a precision genetic tool being put to work in crop breeding that offers benefits for future elite, high-performing crops. Pioneer is moving forward with work on a commercial hybrid.

With CRISPR-Cas it’s possible to do precision gene insertions (or deletions) in a crop genome that boost productivity or enhance other traits. This isn’t a GMO because the work done involves traits from the same species — corn gene into a corn plant, for example.

These old black-and-white photos were colorized

Posted by in category: robotics/AI

Researchers at Waseda University in Tokyo have created a way to realistically colorize black-and-white photos without any human intervention for the first time ever. The team’s approach is based on convolutional neural networks — a type of machine learning originally inspired by the visual cortex of a cat.

Tiny Spacecraft to Take on Journey to Alpha Centauri

Draper’s ChipSat Research Could Make Stamp-Sized Spacecraft Functional for Interstellar Mission

CAMBRIDGE, MA – Chip-sized spacecraft will be beamed about 25 trillion miles to Alpha Centauri within 20 years of launch – a mission that would otherwise take 30,000 years – thanks to an engineering project sponsored by the Breakthrough Starshot team. Since 2010, Draper and Cornell University have collaborated on research into spacecraft that could be reduced to the size of a postage stamp and dubbed “ChipSats.” While ChipSats are small and inexpensive to launch, they face challenges far different from those of larger spacecraft and require a completely different approach to space missions.

Due to their tiny size, ChipSats experience disturbances in space in a different manner from large spacecraft. Much like a dinghy is greatly affected by waves that cannot move an oil tanker, the importance of small environmental forces, such as solar radiation pressure and aerodynamic drag, is magnified for ChipSats. This represents a challenge for completing the journey to Alpha Centauri and pointing precisely to send data back to Earth. But it is also an opportunity for developing new guidance and control approaches that take advantage of the environment.

At CERN, eight-inch sensor chips from Infineon could reveal the mysteries of the universe

Posted by in categories: computing, cosmology, electronics, particle physics

Ninety-five percent of the universe is still considered unexplored. Scientists at CERN, the world’s largest particle physics research center, located in Geneva, are working on solving these mysteries. In May 2012, researchers there discovered the so-called Higgs Boson, whose prediction won Peter Higgs and François Englert the Nobel prize in physics. One of the things CERN scientists are researching at the moment is dark matter: Although it may well have five times the mass of visible matter in the universe, this extent can only be indirectly proved. With a bit of luck, CERN will also succeed in generating dark matter.

A unique sensor chip can contribute to proving the existence of : It is eight inches or 15 cm x 10 cm and was developed jointly by Infineon Technologies Austria and the Austrian Academy of Sciences’ Institute of High Energy Physics (HEPHY). Tens of thousands of these silicon components could be used at CERN in the near future. They are not only more economical to produce than previous sensors, which measured up to six inches. The components also stand up better to constant radiation and thus age slower than the previous generation. Planned experiments will scarcely be possible without resistant sensors.

The experiments at CERN are analyzing the structure of matter and the interplay among elementary particles: Protons are accelerated almost to the speed of light and then made to collide, giving rise to new particles whose properties can be reconstructed with various detectors. “In and cosmology, there are many questions that are still open and to which mankind still has no answer,” says Dr. Manfred Krammer, head of the Experimental Physics Department at CERN. “To make new advances in these areas, we need a new generation of particle sensors. Cooperation with high-tech companies like Infineon allows us to develop the technologies we need for that.”

Can AI fix education? We asked Bill Gates

Posted by in categories: education, mobile phones, robotics/AI

Bill Gates on personalized learning, AI in education.


The rise of smartphones has transformed the way students communicate and entertain themselves. But the classrooms they spend so much of their time in remain stubbornly resistant to transformation. On one hand, technology has long had a home in classrooms — I learned to type on an Apple IIe in the late 1980s. But for most schools, the approach to teaching remains stubbornly one-size-fits-all: a single teacher delivering the same message to a group of about 30 students, regardless of their individual progress.

Bill Gates is working to change all that. Through the Bill and Melinda Gates Foundation, Microsoft’s co-founder and chairman has invested more than $240 million to date in a developing field known as “personalized learning.” It’s a diffuse set of initiatives, led mostly by private companies, to develop software that creates individual lesson plans for students based on their performance, coaching them through trouble spots until they have mastered the subject at hand. Teachers still play a central role in the classroom, but they do less lecturing and more one-on-one coaching.

Genetics startup Twist Bioscience is working with Microsoft to store the world’s data in DNA

Posted by in categories: biotech/medical, business, genetics, information science

“[Using DNA,] you could fit all the knowledge in the whole world inside the trunk of your car,” Twist Bioscience CEO Emily Leproust told TechCrunch.


Twist Bioscience, a startup making and using synthetic DNA to store digital data, just struck a contract with Microsoft and the University of Washington to encode vast amounts of information on synthetic genes.

Big data means business and the company able to gather a lot of it is very valuable to investors and stockholders. But that data needs to be stored somewhere and can cost a lot for the upkeep.
