If 2023 was the year artificial intelligence became a household topic of conversation, it’s in many ways because of Sam Altman, CEO of the artificial intelligence research organization OpenAI.
The OpenAI CEO spoke candidly about his November ousting and reinstatement at the company and the risks and rewards AI can bring in the future.

Enceladus’ ice plumes may hold the building blocks of life. Researchers have shown unambiguous laboratory evidence that amino acids transported in the ice plumes of Saturn’s moon, Eceladus, can survive impact speeds of up to 4.2 km/s, supporting their detection during sampling by spacecraft.
As astrophysics technology and research continue to advance, one question persists: is there life elsewhere in the universe? The Milky Way galaxy alone has hundreds of billions of celestial bodies, but scientists often look for three crucial elements in their ongoing search: water, energy and organic material. Evidence indicates that Saturn’s icy moon Enceladus is an ‘ocean world’ that contains all three, making it a prime target in the search for life.
During its 20-year mission, NASA’s Cassini spacecraft discovered that ice plumes spew from Enceladus’ surface at approximately 800 miles per hour (400 m/s). These plumes provide an excellent opportunity to collect samples and study the composition of Enceladus’ oceans and potential habitability.
A problem that has long been a focal point of research for the famous Game of Life, has finally been solved.
Weeks after introducing a potentially game-changing “Uni-wheel” drive system for EVs, Hyundai and Kia are showing off another next-generation technology to keep EV drivers safer during inclement weather. Today, Kia and Hyundai introduced a new snow chain-integrated tire that utilizes shape memory alloy modules inside the wheel. See how this incredible new tech works in the video below.
As EVs continue to saturate the global automotive market, their respective technologies are evolving to benefit consumers. Now more than ever, these electric vehicles drive farther, charge faster, and come equipped with exciting new technologies like vehicle-to-load (V2L) capabilities and Plug & Charge.
Hyundai Motor Group has been one of the early proponents of such technologies, featuring them in EVs atop its E-GMP platform. In fact, Hyundai and Kia especially have rolled out some exciting technologies throughout the electric mobility segment and allocated considerable funds to R&D to explore new engineering breakthroughs.
A nitrogen-vacancy (NV) center is a defect in the crystal structure of diamond, where a nitrogen atom replaces a carbon atom in the diamond lattice and a neighboring site in the lattice is vacant. This and other fluorescent defects in diamond, known as color centers, have attracted researchers’ attention owing to their quantum properties, such as single-photon emission at room temperature and with long coherence time. Their many applications include quantum information encoding and processing, and cell marking in biological studies.
Microfabrication in diamond is technically difficult, and nanodiamonds with color centers have been embedded in custom-designed structures as a way of integrating these quantum emitters into photonic devices. A study conducted at the University of São Paulo’s São Carlos Institute of Physics (IFSC-USP) in Brazil has established a method for this, as described in an article published in the journal Nanomaterials.
“We demonstrated a method of embedding fluorescent nanodiamonds in microstructures designed for this purpose, using two-photon polymerization [2PP],” Cleber Mendonça, a professor at IFSC-USP and last author of the article, told Agência FAPESP. “We studied the ideal concentration of nanodiamond in the photoresist to achieve structures with at least one fluorescent NV center and good structural and optical quality.” The photoresist is a light-sensitive material used in the fabrication process to transfer nanoscale patterns to the substrate.
Engelbart grew up on a small farm in Southeast Portland where his father operated a radio store.
He graduated from Franklin High School in 1942 and enrolled at Oregon State College, now called Oregon State University, to study electrical engineering.
When World War II interrupted his studies, he spent two years working as a Navy radio and radar technician in the Philippines.
Tiny made from human windpipe cells encouraged damaged neural tissue to repair itself in a lab experiment — potentially foreshadowing a future in which creations like this patrol our bodies, healing damage, delivering drugs, and more.
The background: In a study published in 2020, researchers at Tufts University and the University of Vermont (UVM) harvested and incubated skin cells from frog embryos until they were tiny balls.
They then sculpted the spheres into specific shapes — dictated by an algorithm — and added layers of cardiac stem cells to them in precise locations.
Cloning, a topic that has captured the imagination of many, continues to be a subject of scientific interest, ethical debates, and speculative musings. While its various forms and implications have been widely discussed, this article aims to provide an overview of cloning, present examples of successful cloning in different organisms, explore the mechanisms involved, and address the reports and speculations surrounding possible human cloning.
Understanding Cloning: Cloning is the process of creating an organism that is genetically identical to another individual. It can occur naturally, such as with identical twins, or it can be achieved artificially through scientific techniques. Artificial cloning techniques include somatic cell nuclear transfer (SCNT), where the nucleus of a donor cell is transferred into an enucleated egg cell, and reproductive cloning, which aims to create a living copy of an existing organism.
