The Dutch shipbuilder Royal Huisman used an engineering process developed by the European Space Agency (ESA) for space missions in the design of the superyacht Sea Eagle II — expected to become the largest aluminum sailing yacht in the world upon delivery to its owner this Spring.
Engineering design used by the European Space Agency was used to create the largest aluminum superyacht.
Researchers have converted human stem cells into insulin-producing cells and demonstrated in mice infused with such cells that blood sugar levels can be controlled and diabetes functionally cured for nine months.
The findings, from researchers at Washington University School of Medicine in St. Louis, are published online Feb. 24 in the journal Nature Biotechnology.
“These mice had very severe diabetes with blood sugar readings of more than 500 milligrams per deciliter of blood — levels that could be fatal for a person — and when we gave the mice the insulin-secreting cells, within two weeks their blood glucose levels had returned to normal and stayed that way for many months,” said principal investigator Jeffrey R. Millman, PhD, an assistant professor of medicine and of biomedical engineering at Washington University.
QuTech has resolved a major issue on the road toward a working large-scale quantum computer. QuTech, a collaboration of TU Delft and TNO, and Intel have designed and fabricated an integrated circuit that can controlling qubits at extremely low temperatures. This paves the way for the crucial integration of qubits and their controlling electronics in the same chip. The scientists have presented their research during the ISSCC Conference in San Francisco.
Quantum computers
“This result brings us closer to a large-scale quantum computer which can solve problems that are intractable by even the most powerful supercomputers. Solutions to those problems can make a strong impact on everyday life, for instance in the fields of medicine and energy,” said team lead Fabio Sebastiano from QuTech and the Faculty of Electrical Engineering, Mathematics and Computer Science.
Labs around the world are racing to develop new computing and sensing devices that operate on the principles of quantum mechanics and could offer dramatic advantages over their classical counterparts. But these technologies still face several challenges, and one of the most significant is how to deal with “noise”—random fluctuations that can eradicate the data stored in such devices.
A new approach developed by researchers at MIT could provide a significant step forward in quantum error correction. The method involves fine-tuning the system to address the kinds of noise that are the most likely, rather than casting a broad net to try to catch all possible sources of disturbance.
The analysis is described in the journal Physical Review Letters, in a paper by MIT graduate student David Layden, postdoc Mo Chen, and professor of nuclear science and engineering Paola Cappellaro.
Circa 2019
Nature breaks everything down—eventually. It’s time to accelerate the process, by engineering enzymes or microbes to chop plastic polymers into bits.
Fuel cells turn chemicals into electricity. Now, a U of T Engineering team has adapted technology from fuel cells to do the reverse: harness electricity to make valuable chemicals from waste carbon (CO2).
“For decades, talented researchers have been developing systems that convert electricity into hydrogen and back again,” says Professor Ted Sargent (ECE), one of the senior authors of a paper published today in Science. “Our innovation builds on that legacy, but by using carbon-based molecules, we can plug directly into existing hydrocarbon infrastructure.”
In a hydrogen fuel cell, hydrogen and oxygen come together on the surface of a catalyst. The chemical reaction releases electrons, which are captured by specialized materials within the fuel cell and pumped into a circuit.
This handheld 3D printer deposits layers of skin tissue, and could one day help to heal deep wounds. Instead of waiting for skin patches to grow in a Petri dish, you apply it directly.
A team of Canadian scientists has successfully applied skin tissue to burn wounds using a handheld 3D printer. This technology may become a game-changer in the way severe burn victims are treated.
The handheld skin 3D printer, the work of scientists at the University of Toronto Engineering and Sunnybrook Hospital, was first shown back in 2018. Since then it has undergone a major redesign that improves upon the initial model’s functionality.
Traditionally, India’s best and brightest tech talent has emigrated to the United States for lucrative job opportunities. But now they’re putting their entrepreneurial spirit and engineering skills to use at home.

An international group of researchers has made graphene more affordably and with a lower environmental impact than current chemical methods by using bacteria.
Graphene is a very strong and conductive material that could revolutionize electronics and engineering. However, producing graphene in large quantities requires lots of energy and involves toxic chemicals, such as hydrazine, which damages the nervous system.
Researchers from the Delft University of Technology in the Netherlands and the University of Rochester in the US have worked to overcome these problems by using bacteria to produce graphene. Their work has been published in the journal ChemOpen.
