A British aerospace startup is working on a fusion rocket it says will slash the amount of time it takes astronauts to travel to Mars and beyond — allowing humans to explore places that are currently far out of reach.

The challenge: Long-term exposure to microgravity and cosmic radiation can cause serious health issues for astronauts. That means NASA needs to keep its future Mars missions short enough that astronauts come home healthy — less than 4 years should work.

Using our current rocket propulsion technology, though, it’s going to take seven months just to get astronauts to Mars. Factor in the amount of time to get back to Earth, and nearly a third of a Mars astronaut’s mission is just going to be dedicated to the commute.

FOX News Channel (FNC) is a 24-hour all-encompassing news service delivering breaking news as well as political and business news. The number one network in cable, FNC has been the most-watched television news channel for 18 consecutive years. According to a 2020 Brand Keys Consumer Loyalty Engagement Index report, FOX News is the top brand in the country for morning and evening news coverage. A 2019 Suffolk University poll named FOX News as the most trusted source for television news or commentary, while a 2019 Brand Keys Emotion Engagement Analysis survey found that FOX News was the most trusted cable news brand. A 2017 Gallup/Knight Foundation survey also found that among Americans who could name an objective news source, FOX News was the top-cited outlet. Owned by FOX Corporation, FNC is available in nearly 90 million homes and dominates the cable news landscape, routinely notching the top ten programs in the genre.

US studio Olson Kundig Architects has utilised a variety of wooden storm shutters and deep roof overhangs for a Hawaiian holiday home called Hale Napo’o.

Hale Napo’o, which translates to Sunset House, is located on the northern coast of Kauai, an island in the Hawaiian archipelago.

The clients desired a family retreat that opened up to the landscape and ushered in breezes from Hanalei Bay.

Both A4 and LEARN suffered from several methodological hiccups, to the extent that one might consider A4, at least, a failed study. In 2017, after A4 was well underway, the leaders decided to up the solanezumab dosage substantially, from 400 mg to 1,600 mg per dose, and also to extend the follow-up period from the originally planned 3.2 years to 4.5 years, so that effects of the dosage increase could be captured adequately.

Meanwhile, LEARN commenced at about the same time. That meant that less than 3 years later, both studies were hit by the COVID-19 pandemic and its associated disruptions. Many study sites shut down, and the investigators had to resort to home infusions in some places to keep the study going. Aisen and Sperling acknowledged that these issues complicated data collection, analysis, and interpretation. But there was no suggestion that these problems might have obscured a genuine beneficial effect from solanezumab.

Taken together, said Sperling, the results from A4 and LEARN indicate that “amyloid reduction may be necessary to slow progression even at the stage of preclinical [Alzheimer’s disease].”

Italian architecture studio Renzo Piano Building Workshop has completed the landmark Istanbul Modern museum, which is its first project in Turkey.

Over 10,000 square metres in size, Istanbul Modern is an art museum on Karaköy waterfront, a historic area in Istanbul where the Bosphorus and Golden Horn waterways meet.

It has a top-heavy form made up of three stacked rectilinear volumes, designed by Renzo Piano Building Workshop to evoke the shape of a ship.

Why aren’t there more robots in homes? This a surprising complex question — and our homes are surprisingly complex places. A big part of the reason autonomous systems are thriving on warehouse and factory floors first is the relative ease of navigating a structured environment. Sure, most systems still require a space be mapped prior to getting to work, but once that’s in place there tends to be little in the way of variation.

Homes, on the other hand, are kind of a nightmare. Not only do they vary dramatically from unit to unit, they’re full of unfriendly obstacles and tend to be fairly dynamic, as furniture is moved around or things are left on the floor. Vacuums are the most prevalent robots in the home, and they’re still being refined after decades on the market.

This week, researchers at MIT CSAIL are showcasing PIGINet (Plans, Images, Goal, and Initial facts), which is designed to bring task and motion planning to home robotic systems. The neural network is designed to help streamline their ability to create plans of action in different environments.

YouTube is experimenting with AI-generated quizzes on its mobile app for iOS and Android devices, which are designed to help viewers learn more about a subject featured in an educational video. The feature will also help the video-sharing platform get a better understanding of how well each video covers a certain topic.

The AI-generated quizzes, which YouTube noted on its experiments page yesterday, are rolling out globally to a small percentage of users that watch “a few” educational videos, the company wrote. The quiz feature is only available for a select portion of English-language content, which will appear on the home feed as links under recently watched videos.

Not all of YouTube’s experiments make it to the platform, so it will be interesting to see if this one sticks around. We’re not sure how many people — especially if they’re no longer in school — want to take a quiz while they scroll through videos.
