It’s proving tough to reign in systems like ChatGPT
Did a human.
Did a human write that, or ChatGPT? It can be hard to tell — perhaps too hard, its creator OpenAI thinks, which is why it is working on a way to “watermark” AI-generated content.

Brodmann17, an Israeli computer vision technology startup that developed a novel approach to take on a marketplace dominated by Mobileye, shut down this week. Brodmann17’s co-founder and CEO Adi Pinhas posted a message on LinkedIn announcing the move, stating that while the company would not be able to bring its products to the mass market as hoped, “we do get comfort that our innovation will hopefully influence the market thinking and others will proceed in the mission of creating safer mobility to everyone.”
In a subsequent interview, Pinhas told TechCrunch that “there is a strong feeling of sorrow as we proved the technology, there is outstanding demand and we have customers in production.
Pelorus, a provider of experiential travel and yachting, has partnered with Swedish aviation company OceanSky Cruises, the “airline of airships,” to promote the advancement of ultra-sustainable airship travel.
Pelorus will provide thorough research, planning, and logistics as OceanSky’s “expedition partner” to create individualized private experiences before, after, and onboard OceanSky Cruises’ fleet of premier “lighter than air” airships, according to a press release by the company last week.
Keith Downing is a professor of Computer Science at the Norwegian University of Science and Technology, specializing in Artificial Intelligence and Artificial Life. He has a particular interest in evolutionary algorithms, which have applications ranging from the development of the Mars Rover antenna, patented circuits, early driverless cars, to even art. For computer scientists to learn from nature, he believes there needs to be a shift in our traditional ways thinking.
About TEDx, x = independently organized event.
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations).

Papilio antimachusPhoto by Luis Miguel Bugallo Sánchez (Lmbuga Commons)(Lmbuga Galipedia); CC-BY-SA-3.0 The Giant African Swallowtail (Papilio antimachus) is a species of giant butterfly in the family of swallowtail butterflies. As a giant butterfly, Papilio antimachus belongs to the family Papilionidae and has a wingspan of between 7.1 and 9.1 inches. It is not unusual to see wings that can measure 10 inches or more from tip to tip.
Robert McNair Price (born 7 July 1954) is an American New Testament scholar who argues against the existence of a historical Jesus (the Christ myth theory). He taught theology and religious studies at the Johnnie Colemon Theological Seminary. Price is a professor of biblical criticism at the Center for Inquiry Institute, and the author of a number of books on biblical studies and the historicity of Jesus.
A former Baptist minister, Price was the editor of the Journal of Higher Criticism from 1994 until it ceased publication in 2003. He has also written extensively about the Cthulhu Mythos, a “shared universe” created by the writer H. P. Lovecraft. He also co-wrote a book with his wife, Carol Selby Price, Mystic Rhythms: The Philosophical Vision of Rush (1999), on the rock band Rush.
A team of researchers in China have developed a high-conductivity material that could greatly reduce contact resistance and Schottky barrier height within critical parts of electronic and optoelectronic microchips, paving the way for computer and digital imaging components that consume less power relative to their performance than existing chipsets.
The material, molybdenum disulfide (MoS2) is so thin that it falls into a classification of two-dimensional. That is, it is grown in sheets extending in two directions, X and Y, but virtually immeasurable on a Z axis because the material is often only a single molecule or atom in height.
The team, led by Professor Dong Li and Professor Anlian Pan, College of Materials Science and Engineering at Hunan University, published their findings in Nano Research.
A research team from Skoltech, Aalto University, and Kurnakov Institute has recently developed a new, versatile and simple approach to using carbon nanotubes for manufacturing carbon nanotube-polymer nanocomposites. The method is reported in Carbon and involves making briquettes—dense packages of carbon nanotube powders. Nanocomposites made with briquettes perform equally well as those made from the more expensive masterbatches, which are also polymer-specific—that is, less versatile.
“We believe the use of dense briquettes of carbon nanotubes can significantly facilitate the development of the carbon nanotube composite industry. This technique is cheap and applicable to a broad variety of polymer matrices, without sacrificing any of the electrical and thermal properties of the final material,” the lead author of the study, Skoltech Ph.D. student Hassaan Butt, stated.
Carbon nanotubes have been intensively investigated for decades by researchers from academia and industry because of their unique combination of electrical, thermal, and mechanical properties. Meanwhile, polymer-based nanocomposites have come to be the largest carbon nanotube application and the one closest to widespread integration into everyday life. It is easy to understand why: The smallest amounts of nanotubes added to a polymer endow the material with fundamentally new properties, such as electrical conductivity and piezoresistivity, as well as crucially enhancing its thermal and mechanical properties.
Lawrence Livermore National Laboratory (LLNL) scientists are scaling up the production of vertically aligned single-walled carbon nanotubes (SWCNT) that could revolutionize diverse commercial products ranging from rechargeable batteries, automotive parts and sporting goods to boat hulls and water filters. The research appears in the journal Carbon.
Most CNT production today is used in bulk composite materials and thin films, which rely on unorganized CNT architectures. For many uses, organized CNT architectures such as vertically aligned forests provide important advantages for exploiting the properties of individual CNTs in macroscopic systems.
“Robust synthesis of vertically-aligned carbon nanotubes at large scale is required to accelerate deployment of numerous cutting-edge devices to emerging commercial applications,” said LLNL scientist and lead author Francesco Fornasiero. “To address this need, we demonstrated that the structural characteristics of single-walled CNTs produced at wafer scale in a growth regime dominated by bulk diffusion of the gaseous carbon precursor are remarkably invariant over a broad range of process conditions.”
