Optical data communications lasers can transmit several tens of terabits per second, despite a huge amount of disruptive air turbulence. ETH Zurich scientists and their European partners demonstrated this capacity with lasers between the mountain peak, Jungfraujoch, and the city of Bern in Switzerland. This will soon eliminate the necessity of expensive deep-sea cables.

The backbone of the internet is formed by a dense network of fiber-optic cables, each of which transports up to more than 100 terabits of data per second (1 terabit = 10¹² digital 1/0 signals) between the network nodes. The connections between continents take place via deep sea networks—which is an enormous expense: a single cable across the Atlantic requires an investment of hundreds of millions of dollars. TeleGeography, a specialized consulting firm, announced that there currently are 530 active undersea cables—and that number is on the rise.

Soon, however, this expense may drop substantially. Scientists at ETH Zurich, working together with partners from the space industry, have demonstrated terabit optical data transmission through the air in a European Horizon 2020 project. In the future, this will enable much more cost‑effective and much faster backbone connections via near-earth satellite constellations. Their work is published in the journal Light: Science & Applications.

Opera says its generative AI-infused browser is ready for public consumption. Opera One is now out of early access. It’s more broadly available on Windows, Mac and Linux. You can download it from the company’s website.

Opera features an integrated AI called Aria that you can access from the sidebar. You can use a keyboard shortcut (CTRL or Command and /) to start using Aria as well. The AI is also available in Opera’s Android browser starting today.

Aleksandra Radenovic, head of the Laboratory of Nanoscale Biology in the School of Engineering, has worked for years to improve nanopore technology, which involves passing a molecule like DNA through a tiny pore in a membrane to measure an ionic current. Scientists can determine DNA’s sequence of nucleotides—which encodes genetic information—by analyzing how each one perturbs this current as it passes through. The research has been published in Nature Nanotechnology.

Currently, the passage of molecules through a nanopore and the timing of their analysis are influenced by random physical forces, and the rapid movement of molecules makes achieving high analytical accuracy challenging. Radenovic has previously addressed these issues with optical tweezers and viscous liquids. Now, a collaboration with Georg Fantner and his team in the Laboratory for Bio-and Nano-Instrumentation at EPFL has yielded the advancement she’s been looking for—with results that could go far beyond DNA.

Study removes AMR plasmids using a mobile, broad-host-range CRISPR-Cas9 delivery tool.

An estimated 3 million people with severe chest discomfort and slightly increased troponin levels visit emergency rooms each year. When the heart muscle suffers damage due to a heart attack, high amounts of protein troponin are produced. It is still unknown how to diagnose and treat people with chest discomfort with detectable or barely increased troponin.

Now, a new study from researchers at Wake Forest University School of Medicine reveals that cardiac magnetic resonance imaging (MRI), is a safe and valuable tool to help evaluate these complex patients.

The study findings appear online today in Circulation: Cardiovascular Imaging, a journal of the American Heart Association.

CB Insights has unveiled the winners of the seventh annual AI 100 — a list of the 100 most promising private AI companies across the globe.

Around one-third of this year’s winners are focused on AI applications across specific industries — such as visual dubbing for the media & entertainment sector or textile recycling for fashion & retail. A total of 40 vendors are focused on cross-industry solutions, like AI assistants & human-machine interfaces (HMIs), digital twins, climate tech, and smell tech.

Additionally, 27 companies in this cohort are developing tools like vector database tech and synthetic datasets to support AI development.

Near the center of the Milky Way Galaxy sits an immense object that astronomers call Sagittarius A*. This “supermassive” black hole may have grown in tandem with our galaxy, and it’s not alone. Scientists suspect that similar behemoths lurk at the heart of almost all large galaxies in the cosmos.

Some can get really big, said Joseph Simon, postdoctoral researcher in the Department of Astrophysical and Planetary Science at the University of Colorado Boulder.

“The black hole at the center of our galaxy is millions of times the mass of the sun, but we also see others that we think are billions of times the mass of the sun,” he said.
