On Christmas Eve, three days after its launch, Apollo 8 reached its destination, successfully carrying humans closer to the Moon than ever before. Finally, the US had beaten the Soviets to a major lunar milestone.

It would have been possible for the crew to simply loop around the Moon and come straight back to Earth. But since the mission was running smoothly (bar a case of space sickness on the part of Commander Frank Borman), the order was given to enter lunar orbit.

The crew now had to fire the service module’s engine for exactly the right amount of time.

Scientists in California tried to study Alzheimer’s disease from a different perspective and the results may have led them to the cause of the disease.

Researchers at the University of California-Riverside (UCR) recently published results from a study that looked at a protein called tau. By studying the different forms tau proteins take, researchers discovered the difference between people who developed dementia and those who didn’t.

The tau protein was critical for researchers because they wanted to understand what the protein could reveal about the mechanism behind plaques and tangles, two critical indicators doctors look for when diagnosing people with Alzheimer’s.

Elon Musk thinks SpaceX needs to ramp up production of its next-generation Raptor engine soon or face potentially dire consequences, according to media reports.

Raptors will power Starship, the huge, fully reusable vehicle that SpaceX is developing to take people and cargo to the moon, Mars and other distant destinations. Each Starship will need a lot of Raptors — 33 for the giant first-stage booster, called Super Heavy, and six for the upper-stage spacecraft, known as Starship.

An asteroid the size of the Eiffel Tower is heading towards Earth this month and it’s considered an especially unique piece of rock by scientists.

The asteroid 4,660 Nereus is classified as a “potentially hazardous” piece of rock because of its proximity to Earth. On Dec. 11, NASA expects it to be at its closest point to Earth over a 20-year period. The asteroid was discovered back in 1982.

The race to find medical treatments for Covid-19—and future pandemics—is on, driving renewed investments by the healthcare and pharmaceutical industries in Real-World Data (RWD) and Real-World Evidence (RWE). A new report on AI and the real-world studies industry, from Deep Pharma Intelligence (DPI), Evomics Medical and The Yuan (an online forum focused on AI in healthcare, for which I am a contributor), provides fresh insights into this rapidly evolving patient-centric approach to increasing R&D efficiency, accelerating the introduction of new drugs, and improving health outcomes.

Qualcomm kicked off its annual Snapdragon Technology Summit with its new premium smartphone SoC dubbed the Snapdragon Series 8 Gen 1. As expected, the new SoC improves performance and efficiency in every aspect of the chip, but enhancements in AI and image processing are especially important for the next generation of premium smartphones.

The new Series 8 Gen 1 SoC follows the previous Snapdragon 888 generation as Qualcomm’s premium smartphone SoC. And yes, there is a new naming convention with this generation. Rather than continuing to count up until the company runs out of numbers for new products, Qualcomm changed the naming convention to that basic series number (Series, 8, 7, 6, and 4) followed by a generational number, similar to what the company began doing with its Snapdragon 8CX SoCs for PCs. Since this is the first generation of smartphone SoCs to use the new nomenclature, the new family of devices will be “Gen 1”. For now, however, the company only announced the premium chip — the Series 8 Gen 1.

Mexican biologist Ingrid Fetter-Pruneda is studying the longevity and fertility in ants in the hope of helping to develop strategies to avoid, slow down or reverse female reproductive aging in other animals or in humans.

Fetter-Pruneda, an Assistant Professor at the Universidad Nacional Autónoma de México (UNAM), says most animals show a trade-off between longevity and fertility, but one of the most striking features of ants is that the queens are simultaneously very long lived and very fertile, while the workers are short lived and sterile.

“I am trying to figure out the cellular and molecular mechanisms that allow queens to remain fertile throughout their relatively long lives,” Fetter-Pruneda says, “Many molecular pathways are conserved across many species, and new discoveries in ants could help direct research in other organisms.”

In October, world leaders came together for the annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the regulatory body that governs the waters around Antarctica. Yet CCAMLR failed to establish vital protections for Antarctica’s Southern Ocean once again despite resounding international support for the Commission to take sweeping conservation actions.

CCAMLR was first established in 1982 in response to growing commercial interest in Antarctica’s ocean resources, particularly krill. Since then, CCAMLR has passed many conservation measures to protect Antarctica, including measures that established the South Orkney Islands and Ross Sea marine protected areas (MPAs) in 2009 and 2016, respectively. But in recent years, CCAMLR has failed to establish additional MPAs despite the Commission’s formal commitment to establish a network of MPAs around the continent over a decade ago. Today, only about 5% of Antarctica’s Southern Ocean is protected.

What about S-500 makes it so fearsome for stealth fighter jets?

The F-35 is one of the most advanced flying machines ever developed by human beings. Sleek, stealthy, but very expensive, it should dominate the skies for many years to come.

But, has it met its match with the development of the new Russian S-500 surface-to-air missile defense system? Let’s take a look.

What is the Russian S-500 defense system? The S-500 missile defense system, also known as the 55R6M (Triumfator-M) or “Promotey” (“Prometheus”), is a Russian developed surface-to-air (SAM) and anti-ballistic missile system developed to replace the older A-135 missile defense system currently in use. Intended to be used as a supplement, and eventual replacement, to the S-400, it has been in development since 2009, and was originally planned to enter production in 2014 but has been subject to years of delays.
