An international team of researchers have been able to track the distribution of matter across the universe over its whole age. The work used the first light that shone freely in the universe, the Cosmic Microwave Background (CMB), to study the unseen matter of the cosmos and confirm that observations agree with our models.

Now, depending on how you look at it, our understanding of the universe is either pretty good or woefully limited. There is a theory called the Standard Model of Cosmology that has been very good at explaining what we see. That said, two crucial components in it are dark matter and dark energy and we haven’t got the darndest idea of what they are. Dark matter is a misnomer. It is not dark, it is invisible as it doesn’t interact with light, only gravity.

So the team used the Atacama Cosmology Telescope in the high Chilean Andes to observe subtle changes to the CMB due to massive structures such as galaxy clusters (filled with dark matter). The changes provide a map of the distribution of matter visible and invisible in the universe.

Organizations have to figure out the potential implications of tapping generative artificial intelligence tools, such as ChatGPT, while consumers should consider how they establish digital engagement.

Despite its popularity, ChatGPT has been criticized for generating unreliable and biased search results. A recent media report, for example, concluded that ‘ChatGPT Is Pretty Bad At Poetry, According To Poets.’ Yet that doesn’t mean that the literary ability of all AI should be discounted, applications created by INSEAD’s AI lab using exacting rules can potentially be more useful and reliable than ChatGPT.

Sure could’ve used this a few years ago.

Artificial intelligence (AI) is continuing to advance and has now defeated a human fighter pilot in a virtual combat simulation.

This result was achieved in the US Army’s AlphaDogfight competition, which aimed to demonstrate the feasibility of developing autonomous agents capable of defeating enemy aircraft in aerial combat.

They’re not a common thing right now, but the technology of solar sails has recently had some success. In particular, it’s had success in exactly the way JPL has been proposing it be used more—in combination with CubeSats. From 2019 to 2022, a crowdfunded CubeSat project called LightSail 2 run by The Planetary Society “successfully used sunlight alone to change its orbit around Earth,” according to the Society’s website. And just recently, NASA launched a sail-powered CubeSat called Near-Earth Asteroid (NEA) Scout as part of the Artemis I mission.

So, with recent functional missions to point to and inside knowledge of what it takes to complete a successful space mission—from engineering marvels to monetary considerations—the team from JPL is pitching we make a lot more use of this pairing through what they call the Sundiver concept.

“Together, small satellites with lightweight instruments and solar sails offer affordable access to deep regions of the solar system, also making it possible to realize hard-to-reach trajectories that are not constrained to the ecliptic plane,” the preprint reads. “Combining these two technologies can drastically reduce travel times within the solar system, while delivering robust science.”

DEER PARK, Texas (AP) — Fire erupted at a petrochemical plant in the Houston area Friday, leaving five workers hospitalized and sending up a huge plume of smoke visible for miles.

The Harris County Sheriff’s Office said the fire was at a Shell USA Inc. facility in Deer Park, a suburb east of Houston.

Law enforcement received a call to help divert traffic around the plant just after 3 p.m., Harris County Sheriff’s Office spokesman Thomas Gilliland said. The city of Deer Park said in an advisory that there was no shelter-in-place order for residents.

Amazon opened a robotics fulfillment center in Windsor, Connecticut, where workers will process orders alongside bots.

The 3.8 million square-foot facility will have “thousands of robotic systems such as mobile robots and robotic handling systems that help employees deliver for customers everyday,” an Amazon spokesperson told Supply Chain Dive.

More than 2,000 employees will work at the facility, which primarily handles smaller shipments such as books, electronics and toys. The company began processing and delivering customer orders in November 2022, according to a press release.

Engineering organs to replace damaged hearts or kidneys in the human body may seem like something out of a sci-fi movie, but the building blocks for this technology are already in place. In the burgeoning field of tissue engineering, live cells grow in artificial scaffolds to form biological tissue. But to evaluate how successfully the cells develop into tissue, researchers need a reliable method to monitor the cells as they move and multiply.

Now, scientists at the National Institute of Standards and Technology (NIST), the U.S Food and Drug Administration (FDA) and the National Institutes of Health (NIH) have developed a noninvasive method to count the live cells in a three-dimensional (3D) scaffold. The real-time technique images millimeter-scale regions to assess the viability of the cells and how the cells are distributed within the scaffold—an important capability for researchers who manufacture complex biological tissues from simple materials such as living cells.

Their findings have been published in the Journal of Biomedical Materials Research Part A.
