Studies find a densely connected network of neurons that communicate over long distances, rather than across synapses.
It’s an open secret that generative AI is terrible at coming up with original and creative writing.
In many ways, that’s to be expected, given its inherent nature — machine learning systems typically churn through the internet and remix what they’ve gobbled up, often in nonsensical or uninspiring ways.
To remedy the situation, some of Silicon Valley’s biggest AI companies are now resorting to hiring poets and writers with humanity degrees, Rest of World reports, which is an ironic twist, considering publishers have been laying off writers and editors while making big investments in generative AI.
Researchers around the world are working on a network which could connect quantum computers with one another over long distances. Andreas Reiserer, Professor of Quantum Networks at the Technical University of Munich (TUM), explains the challenges which have to be mastered and how atoms captured in crystals can help.
The idea is the same: We use today’s internet to connect computers with one another, while the quantum internet lets quantum computers communicate with one another. But in technical terms the quantum internet is much more complex. That’s why only smaller networks have been realized as yet.
There are two main applications: First of all, networking quantum computers makes it possible to increase their computing power; second, a quantum network will make absolutely interception-proof encryption of communication possible. But there are other applications as well, for example networking telescopes to achieve a previously impossible resolution in order to look into the depths of the universe, or the possibility of synchronizing atomic clocks around the world extremely precisely, making it possible to investigate completely new physical questions.
It is estimated that 95% of the planet’s population has access to broadband internet, via cable or a mobile network. However, there are still some places and situations in which staying connected can be very difficult. Quick responses are necessary in emergency situations, such as after an earthquake or during a conflict. So too are reliable telecommunications networks that are not susceptible to outages and damage to infrastructure, networks can be used to share data that is vital for people’s well-being.
A recent article, published in the journal Aerospace, proposes the use of nanosatellites to provide comprehensive and stable coverage in areas that are hard to reach using long-range communications. It is based on the bachelor’s and master’s degree final projects of Universitat Oberta de Catalunya (UOC) graduate David N. Barraca Ibort.
The paper is co-authored by Raúl Parada, a researcher at the Telecommunications Technological Center of Catalonia (CTTC/CERCA) and a course instructor with the UOC’s Faculty of Computer Science, Multimedia and Telecommunications; Carlos Monzo, a researcher and member of the same faculty; and Víctor Monzón, a researcher at the Interdisciplinary Center for Security Reliability and Trust at the University of Luxembourg.
As part of pioneering the security of satellite communication in space, NASA is funding a groundbreaking project at the University of Miami’s Frost Institute for Data Science and Computing (IDSC) which will enable augmenting traditional large satellites with nanosatellites or constellations of nanosatellites.
These nanosatellites are designed to accomplish diverse goals, ranging from communication and weather prediction to Earth science research and observational data gathering. Technical innovation is a hallmark of NASA, a global leader in the development of novel technologies that enable US space missions and translate to a wide variety of applications from Space and Earth science to consumer goods and to national and homeland security.
With advances in satellite technology and reduced cost of deployment and operation, nanosatellites also come with significant challenges for the protection of their communication networks. Specifically, small satellites are owned and operated by a wide variety of public and private sector organizations, expanding the attack surface for cyber exploitation. The scenario is similar to Wi-Fi network vulnerabilities. These systems provide an opportunity for adversaries to threaten national security as well as raise economic concerns for satellite companies, operators, and users.
From Wi-Fi-connected home security systems to smart toilets, the so-called Internet of Things brings personalization and convenience to devices that help run homes. But with that comes tangled electrical cords or batteries that need to be replaced. Now, researchers reporting in ACS Applied Energy Materials have brought solar panel technology indoors to power smart devices. They show which photovoltaic (PV) systems work best under cool white LEDs, a common type of indoor lighting.
Indoor lighting differs from sunlight. Light bulbs are dimmer than the sun. Sunlight includes ultraviolet, infrared and visible light, whereas indoor lights typically shine light from a narrower region of the spectrum. Scientists have found ways to harness power from sunlight, using PV solar panels, but those panels are not optimized for converting indoor light into electrical energy.
Some next-generation PV materials, including perovskite minerals and organic films, have been tested with indoor light, but it’s not clear which are the most efficient at converting non-natural light into electricity; many of the studies use various types of indoor lights to test PVs made from different materials. So, Uli Würfel and coworkers compared a range of different PV technologies under the same type of indoor lighting.

Broadband internet is so ubiquitous these days that one does not realize its importance until it becomes unavailable. From work to entertainment or staying in touch with family and friends, works on the backbone of high-speed internet delivered through a cable or wirelessly these days.
