Scientists develop new technique to peer into the genome’s spatial architecture

Posted by in categories: biotech/medical, electronics

People who owned black-and-white television sets until the 1980s didn’t know what they were missing until they got a color TV. A similar switch could happen in the world of genomics as researchers at the Berlin Institute of Medical Systems Biology of the Max Delbrück Center (MDC-BIMSB) have developed a technique called Genome Architecture Mapping (“GAM”) to peer into the genome and see it in glorious technicolor. GAM reveals information about the genome’s spatial architecture that is invisible to scientists using solely Hi-C, a workhorse tool developed in 2009 to study DNA interactions, reports a new study in Nature Methods by the Pombo lab.

With a black-and-white TV, you can see the shapes but everything looks grey. But if you have a color TV and look at flowers, you realize that they are red, yellow and white and we were unaware of it. Similarly, there’s also information in the way the genome is folded in three-dimensions that we have not been aware of.

Silicon nose: Small sensor ‘smells’ incipient seizures

Posted by in categories: chemistry, electronics

ALBUQUERQUE, N.M. — In people with epilepsy, seizure-alert dogs can smell small changes in body chemistry and warn of an impending seizure an hour or more before it occurs. Inspired by this feat of nature, a team of researchers has sniffed out a way to replicate the ability with technology.

Remote-Controlled Pill Camera Can Help Diagnose Digestive Issues

Posted by in categories: biotech/medical, electronics

Scientists have developed a pill-shaped, swallowable camera that can be controlled by physicians once ingested to help doctors diagnose digestive issues.

Ingestible pill-shaped endoscopes are not a new idea. Last year, PetaPixel reported on the Pillcam which is just such a device, but it had limitations just like all other swallowable pill cameras: doctors can’t control it once it is ingested.

Are smartphone thermal cameras sensitive enough to uncover PIN codes?

Posted by in categories: electronics, mobile phones

I’ve found a lot of reasons – from finding components that are overheating (which can indicate faulty components), identifying overheating wires and connectors (which can indicate damaged wires or connectors), diagnosing issues with HVAC, find draughts at home, and much, much more.

Former Samsung exec accused of stealing data to build copycat chip plant in China

Posted by in categories: computing, electronics

A former executive of Samsung Electronics stole the juggernaut’s confidential semiconductor data to build a copycat chip facility in China, South Korean prosecutors alleged on Monday.

The 65-year-old defendant, who also previously worked for Korean chipmaker SK Hynix, has been arrested. He has been accused of violating industrial technology protection laws and stealing trade secrets from 2018 to 2019 to establish a copy of Samsung’s semiconductor plant, just 1.5 kilometers away from Samsung chip factory in Xi’an, China.

The ex-Samsung exec’s attempt to build the copycat chip plant allegedly fell through after his backer, purportedly an undisclosed Taiwanese company, canceled more than a $6 billion (approximately 8 trillion won) investment into the project, prosecutors said. Instead, he received capital from investors in China and Taiwan to produce trial chip products based on Samsung’s technology.

The first 110-inch 16K TV screen is here to make your projector feel inadequate

Posted by in category: electronics

Chinese display maker BOE has unveiled a truly massive 110-inch 16K TV, putting the hordes of 4K TVs and projectors on the market to shame.

This seismically large prototype packs in a 16K resolution, with four times as many pixels as an 8K screen, and 16 times the pixel count of 4K. It was shown off at SID Display Week 2023 in Los Angeles, to celebrate BOE’s 30-year anniversary with a showcase of cutting-edge resolution far beyond the average television (via

Telecom-wavelength quantum repeater node transmits quantum information over tens of kilometers

Posted by in categories: electronics, quantum physics

A quarter century ago, theoretical physicists at the University of Innsbruck made the first proposal on how to transmit quantum information via quantum repeaters over long distances, which would open the door to the construction of a worldwide quantum information network.

Now, a new generation of Innsbruck researchers has built a quantum repeater node for the standard wavelength of telecommunication networks and transmitted over tens of kilometers. The study is published in the journal Physical Review Letters.

Quantum networks connect quantum processors or quantum sensors with each other. This allows tap-proof communication and high-performance distributed sensor networks. Between network nodes, quantum information is exchanged by photons that travel through optical waveguides. Over long distances, however, the likelihood of photons being lost increases dramatically.
