Fiber Optics Could Be the Key to Million-Qubit Quantum Computers

Posted by in categories: computing, quantum physics

When the researchers used their system to measure the qubits’ state, they achieved an accuracy of 98 percent, exactly the same as when they carried out the measurement using a conventional electrical cable.

The authors acknowledge that work is already underway to try and reduce the heat produced by current approaches, including the development of thinner wires, proposals to replace wires with superconducting cables, or a process called multiplexing that makes it possible to send many signals over the same cable simultaneously.

But optical fiber is a well-established technology, and is already replacing electrical wires in many areas of computing thanks to its ability to carry far more data. The authors also point out that components used in this experiment were designed to work at room temperature, so optimizing them for cryogenic temperatures could provide significant performance gains.

Four Nigerian Undergrads Leave School to Launch Crypto Remittance Company Flux

Posted by in category: futurism

There’s a new crypto converter on the market for those looking for a more seamless way to send and receive money internationally.

With the emergence of crypto remittance companies in recent years, a group of undergraduates based in Nigeria teamed up to stake their claim in the market. Software engineers Ben Eluan and Osezele Orukpe became the CEO and CTO, respectively, of their company, Flux, a new crypto remittance company that allows merchants to send and receive money from anywhere in the world, TechCrunch reports. Through Flux, users can convert fiat funds into crypto that can be sent to people in other countries without all the time constraints and exorbitant fees.

Machine Learning Faces a Reckoning in Health Research

Posted by in categories: biotech/medical, health, robotics/AI

Univ. of Toronto Researcher: “I did not realize quite how bad [the lack of reproducibility and poor quality in research papers] was.”


Many areas of science have been facing a reproducibility crisis over the past two years, and machine learning and AI are no exception. That has been highlighted by recent efforts to identify papers with results that are reproducible and those that are not.

Two new analyses put the spotlight on machine learning in health research, where lack of reproducibility and poor quality is especially alarming. “If a doctor is using machine learning or an artificial intelligence tool to aid in patient care, and that tool does not perform up to the standards reported during the research process, then that could risk harm to the patient, and it could generally lower the quality of care,” says Marzyeh Ghassemi of the University of Toronto.

Editing the Epigenome for Better Health and a Pathway to Antiaging

Posted by in categories: biotech/medical, health

Didn’t watch the video.


Prof David R. Liu, Professor at Harvard University, the Broad Institute, and HHMI was interviewed by the Sheeky Science Show. In the interview, they discussed how to make precise genome editing safe & efficient using the latest CRISPR tech advances in base editing and prime editing and taking it to the clinic (e.g Beam Therapeutics). They talked about the next frontier, epigenome editing.

Scientists create simple synthetic cell that grows and divides normally

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

**Five years ago, scientists created a single-celled synthetic organism that, with only 473 genes, was the simplest living cell ever known.** However, this bacteria-like organism behaved strangely when growing and dividing, producing cells with wildly different shapes and sizes.

Now, scientists have identified seven genes that can be added to tame the cells’ unruly nature, causing them to neatly divide into uniform orbs. This achievement, a collaboration between the J. Craig Venter Institute (JCVI), the National Institute of Standards and Technology (NIST) and the Massachusetts Institute of Technology (MIT) Center for Bits and Atoms, was described in the journal Cell.

Identifying these genes is an important step toward engineering synthetic cells that do useful things. Such cells could act as small factories that produce drugs, foods and fuels; detect disease and produce drugs to treat it while living inside the body; and function as tiny computers.

Pompeii: Ancient remains are helping scientists learn what happens to a body caught in a volcanic eruption

Posted by in categories: climatology, drones

The recent eruptions in Iceland, vividly captured through dramatic drone footage, have drawn public attention to the immense power of volcanoes. Beautiful though they are, and mesmerizing to watch, they are also deadly.

History has recorded eruptions so spectacular they’ve never been forgotten. These include Krakatoa in 1883, whose explosion was heard around the world and Mount Tambora, which resulted in famines across the northern hemisphere.
