The research group of laser-matter interaction at the Institute of Intense Lasers and Applications (CELIA) at the University of Bordeaux, France, has explored a new glass micro-drilling method using a femtosecond laser in GHz-burst mode.

Publishing in the journal International Journal of Extreme Manufacturing, the research team used a femtosecond laser from Amplitude operating in the GHz-burst regime to study a new glass micromachining method which allows for drilling taper-free, elongated holes with smooth inner walls without any cracks in the glass. Usually, laser drilling with standard single femtosecond pulses results in tapered holes of strongly limited length and rough inner surface.

This new laser-matter interaction regime makes it possible to directly drill holes of high aspect ratio in one single step without any chemical etching. The choice of the -burst parameters was revealed to be very important in order to achieve an outstanding micromachining quality of the machined structures. The GHz-burst mode could pave the way for new applications such as microelectronics where silicon interposers are likely to be replaced by glass interposers.

One afternoon in the fall of 2019, in a grand old office building near the Arc de Triomphe, I was buzzed through an unmarked door into a showroom for the future of surveillance. The space on the other side was dark and sleek, with a look somewhere between an Apple Store and a doomsday bunker. Along one wall, a grid of electronic devices glinted in the moody downlighting—automated license plate readers, Wi-Fi-enabled locks, boxy data processing units. I was here to meet Giovanni Gaccione, who runs the public safety division of a security technology company called Genetec. Headquartered in Montreal, the firm operates four of these “Experience Centers” around the world, where it peddles intelligence products to government officials. Genetec’s main sell here was software, and Gaccione had agreed to show me how it worked.

He led me first to a large monitor running a demo version of Citigraf, his division’s flagship product. The screen displayed a map of the East Side of Chicago. Around the edges were thumbnail-size video streams from neighborhood CCTV cameras. In one feed, a woman appeared to be unloading luggage from a car to the sidewalk. An alert popped up above her head: “ILLEGAL PARKING.” The map itself was scattered with color-coded icons—a house on fire, a gun, a pair of wrestling stick figures—each of which, Gaccione explained, corresponded to an unfolding emergency. He selected the stick figures, which denoted an assault, and a readout appeared onscreen with a few scant details drawn from the 911 dispatch center. At the bottom was a button marked “INVESTIGATE,” just begging to be clicked.

As a rather commercially successful author once wrote, “the night is dark and full of terrors, the day bright and beautiful and full of hope.” It’s fitting imagery for AI, which like all tech has its upsides and downsides.

Art-generating models like Stable Diffusion, for instance, have led to incredible outpourings of creativity, powering apps and even entirely new business models. On the other hand, its open source nature lets bad actors use it to create deepfakes at scale — all while artists protest that it’s profiting off of their work.

What’s on deck for AI in 2023? Will regulation rein in the worst of what AI brings, or are the floodgates open? Will powerful, transformative new forms of AI emerge, à la ChatGPT, disrupting industries once thought safe from automation?

As far as scores go, the laptop version of the RTX 4,080 scored 178,038 points. The Geekbench OpenCL database shows that the average score for an RTX 3,080 Ti laptop GPU is 136,008, and for an RTX 3,080 — 125,425. This means that the upcoming RTX 4,080 may be up to 30% faster than the last-gen RTX 3,080 Ti and up to 42% faster than its predecessor, the RTX 3080.

These scores certainly bode well for the mobile iteration of the RTX 4080. In its desktop version, the card is certainly powerful, but the RTX 4,090 is often a better deal due to the way these cards are priced.

Rumor has it that Nvidia will have several new products up its sleeve, set to come out early in the new year. The desktop RTX 4,070 Ti, which may just be the previously “unlaunched” RTX 4,080 12GB, is said to make an appearance. We may also learn more about upcoming laptop GPUs. Stay tuned for more news during Nvidia’s CES 2023 keynote on January 3.

A team of researchers at Max Planck Institute for Extraterrestrial Physics, working with a colleague at the University of Texas at Austin and another from Green Bank Observatory in West Virginia, has found evidence of ripe conditions for planet formation in the vicinity of two closely orbiting protostars.

In their paper published in The Astrophysical Journal Letters, the group describes their observations and outline what might be learned from future study of the star system.

The work by the team on this new effort came on the heels of work done by another team that discovered a pair of protostars still in the very early stages of their development—in their first 500,000 years of existence. In this new effort, the researchers have taken a closer look at the two protostars and also the environment in which they exist.

In a recent study published in Cell, researchers used a multi-omics approach to profile the gut microbiomes and metabolomes of mothers and infants to determine the vertical and horizontal transmission of bacterial species and strains as well as individual genes and understand the dynamics of the gut microbiome assembly that shape the development of the infant before and after birth.

The vertical transmission of gut bacteria from mother to fetus during pregnancy and the horizontal transfer of microbes through breast milk plays a vital role in the physical and cognitive development of the infant long after birth. Studies have shown associations between the gut microbiota composition of breastmilk and the development of the infant’s immune system, as well as autoimmune conditions and allergies. Furthermore, allergies and autoimmune disorders have also been linked to exogenous proteins in infant formula.

Metabolites produced by gut microbiota are also associated with the infant’s cognitive development. However, the development of gut microbiomes and metabolomes in the perinatal stage and their role in infant development remains unclear.
