In July last year, the American Red Cross declared an emergency blood shortage — it simply wasn’t receiving enough donations to help all the patients that needed blood.
This was first presented at the June 2017 TechVancouver.
In this presentation, Geordie discusses the transition that will soon take place with regards to advancements in artificial intelligence.
It will soon be as easy to produce convincing fake video as it is to lie. We need to be prepared.
A team of researchers at the University of British Columbia has found two types of enzymes that together, can transform type A blood to type O blood in the human gut biome. In their paper published in the journal Nature Microbiology, the group describes their metagenomic study of bacteria in human feces and what they found.
There are four blood types: A, B, AB and O. These types are not compatible for blood transfusions, except for type O, which can be transfused into recipient, making it highly valued. The difference between the blood types is due to sugar molecules known as blood antigens that reside on the surfaces of red blood cells. Those with A-type antigens have A-type blood, those with B-type antigens have B-type blood and those with both antigens have AB-type blood. Type O is different because it does not have any antigens on its surface. An immune response is initiated if blood is found with the wrong type of antigen—since type O red blood cells have none, no immune response is initiated.
Prior research by the team at UBC showed that certain enzymes could be used to convert A, B, or AB to O by removing the antigens. In this new effort, the researchers found that two enzymes working together convert type A blood to O, and that they exist in the human gut biome.
In March, a team of Chinese scientists published a study detailing how they made monkeys smarter by splicing a human gene into their DNA.
The news was met by a wave of backlash. But now, one of the scientists behind the study is defending the team’s work — and pledging to push forward on the controversial research.
Adam Savage has made bullet-proof Iron Man Armor using 3D printed titanium and a flying jet suit from Gravity.
It is more precisely a real-life Titanium Man (comic book enemy of Iron Man).

Can you imagine seeing a Van Gogh painting sitting right off the freeway on your morning commute or aerial ride? One field in Eagan, Minnesota got exactly this when the 67-year-old artist, Stan Herd, transformed it into Van Gogh’s 1889 “Olive Trees.” Herd has been doing similar types of artworks or ‘earthworks’ since 1981. “I realized in my late 20’s that to create my monumental earthworks, beyond the design and actual creation of the work, I had to develop skills in public relations, communications, media relations, logistics, and fund raising,” said Herd on his website. His most recent project took.
Launched in 1962, the Floating Instrument Platform (FLIP) can sink itself on purpose and withstand heavy seas in a vertical position.
A team of researchers from Jülich in cooperation with the University of Magdeburg has developed a new method to measure the electric potentials of a sample at atomic accuracy. Using conventional methods, it was virtually impossible until now to quantitatively record the electric potentials that occur in the immediate vicinity of individual molecules or atoms. The new scanning quantum dot microscopy method, which was recently presented in the journal Nature Materials by scientists from Forschungszentrum Jülich together with partners from two other institutions, could open up new opportunities for chip manufacture or the characterization of biomolecules such as DNA.
The positive atomic nuclei and negative electrons of which all matter consists produce electric potential fields that superpose and compensate each other, even over very short distances. Conventional methods do not permit quantitative measurements of these small-area fields, which are responsible for many material properties and functions on the nanoscale. Almost all established methods capable of imaging such potentials are based on the measurement of forces that are caused by electric charges. Yet these forces are difficult to distinguish from other forces that occur on the nanoscale, which prevents quantitative measurements.
Four years ago, however, scientists from Forschungszentrum Jülich discovered a method based on a completely different principle. Scanning quantum dot microscopy involves attaching a single organic molecule—the quantum dot—to the tip of an atomic force microscope. This molecule then serves as a probe. “The molecule is so small that we can attach individual electrons from the tip of the atomic force microscope to the molecule in a controlled manner,” explains Dr. Christian Wagner, head of the Controlled Mechanical Manipulation of Molecules group at Jülich’s Peter Grünberg Institute (PGI-3).
