Intelsat meets conditions for $3.7 billion C-band clearing payout

Posted by in categories: internet, space

TAMPA, Fla. — Intelsat said Aug. 14 it is due for a $3.7 billion windfall late this year after becoming the latest satellite operator to clear C-band spectrum ahead of schedule for terrestrial 5G telcos in the United States.

Weeks after launching its seventh and final C-band clearing satellite, the company said it had achieved certification for work to move broadcast customers into a narrower swath of the spectrum.

The Federal Communications Commission set a deadline for satellite operators to clear the spectrum by December 2025, but offered them nearly $10 billion in incentive payments if they could make the frequencies available for telcos before Dec. 5, 2023.

Giving AI a Sense of Empathy Could Protect Us From Its Worst Impulses

Posted by in categories: neuroscience, robotics/AI

M3GAN wasn’t malicious. It followed its programming, but without any care or respect for other beings—ultimately including Cady. In a sense, as it engaged with the physical world, M3GAN became an AI sociopath.

Sociopathic AI isn’t just a topic explored in Hollywood. To Dr. Leonardo Christov-Moore at the University of Southern California and colleagues, it’s high time we build artificial empathy into AI—and nip any antisocial behaviors in the bud.

In an essay published last week in Science Robotics, the team argued for a neuroscience perspective to embed empathy into lines of code. The key is to add “gut instincts” for survival—for example, the need to avoid physical pain. With a sense of how it may be “hurt,” an AI agent could then map that knowledge onto others. It’s similar to the way humans gauge each others’ feelings: I understand and feel your pain because I’ve been there before.

Elon Musk, who’s fathered 10 children, reportedly donated $10 million to fund a fertility and population research project

Why don’t humans have tails?

Humans are some of the only animals that don’t have tails. Most mammals use theirs for balance, but since we walk on two legs, we don’t need them.

Perfectly Preserved Dinosaur Embryo Found Inside Fossilized Egg

Posted by in category: education

An incredibly rare, fully articulated dinosaur embryo has been found inside a fossilized egg that had been collecting dust for over a decade in the storage room of a museum in China. Thought to be between 66 and 72 million years old, the unborn specimen reveals an incredible link between dinosaurs and modern birds.

Belonging to a group of feathered, toothless theropods known as oviraptorosaurs, the unhatched creature is estimated to be about 27 centimeters (10.6 inches) long, and marks the first discovery of a dinosaur embryo displaying a posture that is typical of present-day bird embryos. Shortly before hatching, modern birds engage in a series of maneuvers known as tucking, which involves curving the body and bringing the head down under the wing, yet the evolutionary origins of this behavior had until now remained unknown.

Reporting their discovery in a 2021 paper, the study authors explain that their specimen – nicknamed Baby Yingliang – was found with its head “ventral to the body, with the feet on either side, and the back curled along the blunt pole of the egg.” Such a posture, they say, is “previously unrecognized in a non-avian dinosaur, but reminiscent of a late-stage modern bird embryo.”

Uncovering the local atomic structure of zeolite using optimum bright-field scanning transmission electron microscopy

Posted by in categories: engineering, nanotechnology

Zeolites have unique porous atomic structures and are useful as catalysts, ion exchangers and molecular sieves. It is difficult to directly observe the local atomic structures of the material via electron microscopy due to low electron irradiation resistance. As a result, the fundamental property-structure relationships of the constructs remain unclear.

Recent developments of a low-electron dose imaging method known as optimum bright-field scanning transmission electron microscopy (OBF STEM) offers a method to reconstruct images with a high signal-to-noise ratio with high dose efficiency.

In this study, Kousuke Ooe and a team of scientists in engineering and nanoscience at the University of Tokyo and the Japan Fine Ceramics Center performed low-dose atomic resolution observations with the method to visualize atomic sites and their frameworks between two types of zeolites. The scientists observed the complex atomic structure of the twin-boundaries in a faujasite-type (FAU) zeolite to facilitate the characterization of local atomic structures across many electron beam-sensitive materials.

Scientists develop efficient spray technique for bioactive materials

Posted by in categories: biotech/medical, materials

Rutgers University scientists have devised a highly accurate method for creating coatings of biologically active materials for a variety of medical products. Such a technique could pave the way for a new era of transdermal medication, including shot-free vaccinations, the researchers said.

Writing in Nature Communications, the researchers described a new approach to deposition, an industrial spray-coating process. Essentially, the team developed a way to better control the target region within a spray zone as well as the electrical properties of microscopic particles that are being deposited. The greater command of those two properties means that more of the spray is likely to hit its microscopic target.

Scientists discover novel way of reading data in antiferromagnets, unlocking their use as computer memory

Posted by in categories: computing, materials

Scientists led by Nanyang Technological University, Singapore (NTU Singapore) investigators have made a significant advance in developing alternative materials for the high-speed memory chips that let computers access information quickly and that bypass the limitations of existing materials.

They have discovered a way that allows them to make sense of previously hard-to-read data stored in these alternative materials, known as antiferromagnets.

Researchers consider antiferromagnets to be attractive materials for making computer memory chips because they are potentially more energy efficient than traditional ones made of silicon. Memory chips made of antiferromagnets are not subject to the size and speed constraints nor corruption issues that are inherent to chips made with certain magnetic materials.

Gold buckyballs, oft-used nanoparticle ‘seeds’ are one and the same

Posted by in categories: nanotechnology, particle physics

Rice University chemists have discovered that tiny gold “seed” particles, a key ingredient in one of the most common nanoparticle recipes, are one and the same as gold buckyballs, 32-atom spherical molecules that are cousins of the carbon buckyballs discovered at Rice in 1985.

Carbon buckyballs are hollow 60-atom molecules that were co-discovered and named by the late Rice chemist Richard Smalley. He dubbed them “buckminsterfullerenes” because their atomic structure reminded him of architect Buckminster Fuller’s geodesic domes, and the “fullerene” family has grown to include dozens of hollow molecules.

In 2019, Rice chemists Matthew Jones and Liang Qiao discovered that golden fullerenes are the gold “seed” particles chemists have long used to make gold nanoparticles. The find came just a few months after the first reported synthesis of gold buckyballs, and it revealed chemists had unknowingly been using the golden molecules for decades.
