Smell has the power to transport us across time and space. It could be the sweet fragrance of jasmine, or the musty scent of algae. Suddenly, you are back at your childhood home, or under the burning sun of a distant shore.

Iowa State University gets $1.4 million to buy 3D concrete printer for low-cost homebuilding

Iowa’s first 3D-printed home could be ready for its new owners by this time next year.

The Iowa Economic Development Authority on Friday approved $1.4 million for the Iowa State University College of Design to purchase a 3D printer capable of producing concrete houses. Its goal is to build a neighborhood of up to 34 3D-printed homes in Hamburg, a southwest Iowa town recovering from a massive flood two years ago.

The agency’s director, Debi Durham, said the college also will develop a curriculum for training contractors on 3D printing and new state building codes in order to allow wide use of the technique in Iowa.

More than 21,000 evacuated as heavy rains continue to lash flood-hit Malaysia

KUALA LUMPUR: More than 21,000 people affected by Malaysia’s worst flooding in years — most of them in Selangor — were sheltering in relief centres on Sunday (Dec 19).

Prime Minister Ismail Sabri Yaakob announced the government would allocate an initial sum of RM100 million for house and infrastructure repairs, and will provide financial aid to affected households.

In a Facebook post, the prime minister said he had “directed all ministries to double up efforts in helping flood operations especially in the severely affected areas as soon as possible”.

Reddit-trained artificial intelligence warns researchers about… itself

But wait, should we believe it?


An artificial intelligence warning AI researchers about the dangers of AI sounds like the setup of a delightful B movie, but truth is often stranger than fiction.

A professor and a fellow at the University of Oxford came face to face with that reality when they invited an AI to participate in a debate at the Oxford Union on, you guessed it, the ethics of AI. Specifically, as Dr. Alex Connock and Professor Andrew Stephen explain in the Conversation, the prompt was “This house believes that AI will never be ethical.” The AI, it seems, agreed.

“AI will never be ethical,” argued the Megatron-Turing Natural Language Generation model, which was notably trained on Wikipedia, Reddit, and millions of English-language news articles published between 2016 and 2019. “It is a tool, and like any tool, it is used for good and bad.”

How Sand Mining Is Quietly Creating A Major Global Environmental Crisis | Forbes

Globally, it’s estimated that we mine as much as 50 billion metric tonnes of sand every year to build our roads, bridges, skyscrapers, homes and more. Rapid urbanization around the world has made sand a high value commodity, so much so that, for some, it’s even worth killing for. But not all sand is the same, and experts say some mining operations are damaging ecosystems, infrastructure and putting people in danger around the world.

Building a private space station: Q&A with Axiom Space CTO Matt Ondler

In 2020, Houston-based company Axiom Space got a NASA contract of its own, worth up to $140 million, to deliver at least one habitable private module to the ISS. Axiom plans to launch its first element to the orbiting lab in late 2024, then send several more up over the next few years. Eventually, the connected Axiom modules will detach from the ISS, leaving their natal nest like a bird that has learned how to fly.

Axiom has other irons in the spaceflight fire as well. For instance, the company has booked four commercial crewed flights to the ISS with SpaceX, the first of which is scheduled to launch in February.

3D Printed Architecture that prove the endless possibilities of this innovative technique!

Nowadays almost everything is being 3D printed, so why should architecture be an exception? Many architectural firms are adopting 3D printing as their preferred technique to build structures. And 3D printed architecture is slowly but surely gaining a lot of popularity and momentum. This emerging trend is paving a path for itself in modern architecture. And I mean, no wonder, it has a ton of benefits! It’s a simple, efficient, and innovative technique that lowers the risks of errors, and also manages to save on time. 3D printing eradicates a lot of tedious steps during the construction process and simplifies it. It is being used to build homes, habitats on Mars, and even floating islands! The potential and possibilities of 3D printing in architecture are endless and mind-blowing. We’ve curated a collection of 3D-printed architectural structures that are our absolute favorites – from a 3D printed sustainable office pod to a 3D printed housing community for the homeless, every single one of these designs unleashes the magic and potential of 3D printing!

Chinese rover spots ‘mystery house’ on far side of Moon

While the nature of the object can only be speculated until Yutu-2 gets closer, it is unlikely to be a bunker left behind by an interplanetary species.

It is more likely to be a boulder or a piece of debris, like several others in that region of the moon.

The Yutu-2 rover was launched in 2018 by China as part of the Chang’e-4 lunar lander mission. It entered lunar orbit on December 12, 2019, before scripting history on January 3, 2020, by becoming the first mission to accomplish a soft landing on the lunar surface.
