A team of researchers at OpenAI, a San Francisco artificial intelligence development company, has added a new module to its GPT-3 autoregressive language model. Called DALL·E, the module excerpts text with multiple characteristics, analyzes it and then draws a picture based on what it believes was described. On their webpage describing the new module, the team at OpenAI describe it as “a simple decoder-only transformer” and note that they plan to provide more details about its architecture and how it can be used as they learn more about it themselves.

GPT-3 was developed by the company to demonstrate how far neural networks could take text processing and creation. It analyzes user-selected text and generates new text based on that input. For example, if a user types “tell me a story about a dog that saves a child in a fire,” GPT-3 can create such a story in a human-like way. The same input a second time results in the generation of another version of the story.

In this new effort, the researchers have extended this ability to graphics. A user types in a sentence and DALL·E attempts to generate what is described using graphics and other imagery. As an example, if a user types in “a dog with cat claws and a bird tail,” the system would produce a cartoon-looking image of a dog with such features—and not just one. It would produce a whole line of them, each created using slightly different interpretations of the original text.

Single-objective light sheet fluorescence microscopes are driving innovation in volumetric imaging.

Polaron formation in perovskite solar cells has been indicated in scientific research as a possible factor for making this kind of cell particularly efficient, although the mechanism behind polarons’ action is completely unknown. A U.S. research group has now observed how polaron distortions form and grow.

In a new study published in the journal Nature Medicine, individuals with brown fat had lower prevalences of cardiometabolic diseases, and the presence of brown fat was independently correlated with lower odds of type 2 diabetes, dyslipidemia, coronary artery disease, cerebrovascular disease, congestive heart failure and hypertension.

With their AI approximation for psychedelic trips in place, the team says they can start to probe for similarities with how the human brain processes drugs, citing the structural similarity between neural nets and the human visual cortices.

“The process of generating natural images with deep neural networks can be perturbed in visually similar ways and may offer mechanistic insights into its biological counterpart — in addition to offering a tool to illustrate verbal reports of psychedelic experiences,” Schartner told PsyPost.

Lightweight VTOL Air Ambulances To Be Optimized For Emergency Response

Urban Aeronautics Ltd., a leading Israeli aerospace company, today announced it has reached an agreement to provide four CityHawk VTOL aircraft to Hatzolah Air for emergency medical service (EMS) applications.

In addition, Hatzolah Air will become Urban Aeronautics’ official sales representative and distribution channel to other EMS and rescue organizations worldwide. The companies previously signed an MOU to develop, produce, and market the CityHawk aircraft for EMS applications.

One mouse is hunched over, graying, and barely moves at 7 months old. Others, at 11 months, have sleek black coats and run around. The videos and other results from a new study have inspired hope for treating children born with progeria, a rare, fatal, genetic disease that causes symptoms much like early aging. In mice with a progeria-causing mutation, a cousin of the celebrated genome editor known as CRISPR corrected the DNA mistake, preventing the heart damage typical of the disease, a research team reports today in. Treated mice lived about 500 days, more than twice as long as untreated animals.

“The outcome is incredible,” says gene-therapy researcher Guangping Gao of the University of Massachusetts, who was not involved with the study.

Antiferromagnetism is a type of magnetism in which parallel but opposing spins occur spontaneously within a material. Antiferromagnets, materials that exhibit antiferromagnetism, have advantageous characteristics that make them particularly promising for fabricating spintronic devices.

In contrast with conventional electronic devices, which use the electrical charge of electrons to encode information, spintronics process information leveraging the intrinsic angular momentum of electrons, a property known as “spin.” Due to their ultrafast nature, their insensitivity to external magnetic fields and their lack of magnetic stray fields, antiferromagnets could be particularly desirable for the development of spintronic devices.

Despite their advantages and their ability to store information, most simple antiferromagnets have weak readout magnetoresistivity signals. Moreover, so far physicists have been unable to change the magnetic order of antiferromagnets using optical techniques, which could ultimately allow device engineers to exploit these materials’ ultrafast nature.
