Sea-level rise and wave-driven flooding will negatively impact freshwater resources on many low-lying atoll islands in such a way that many could be uninhabitable in just a few decades. According to a new study published in Science Advances, scientists found that such flooding not only will impact terrestrial infrastructure and habitats, but, more importantly, it will also make the limited freshwater resources non-potable and, therefore, directly threaten the sustainability of human populations.

Most of the world’s atolls are in the Pacific and Indian oceans. The scientists focused on Roi-Namur Island on Kwajalein Atoll in the Republic of the Marshall Islands for their site study from November 2013 to May 2015. The Republic of the Marshall Islands has more than 1,100 low-lying islands on 29 atolls, is home for numerous island nations and hundreds of thousands of people.

Scientists from the U.S. Geological Survey, Deltares, National Oceanic and Atmospheric Administration, and the University of Hawai?i at Mānoa used a variety of climate-change scenarios to project the impact of sea-level rise and wave-driven flooding on atoll infrastructure and freshwater availability. The approach and findings in this study can serve as a proxy for atolls around the world, most of which have a similar morphology and structure, including, on average, even lower land elevations.

Elon Musk took to Twitter Sunday night to announce a new recovery method for an upper stage SpaceX rocket. A balloon — a “giant party balloon” to quote him directly — will ferry part of a rocket to a bounce house. Seriously.

If anyone else proposed this idea they would be ignored, but Elon Musk lately has a way of turning crazy ideas into reality.

It was just in 2012 that SpaceX launched and landed its first rocket and now the company is doing it with rockets significantly larger. And then early this year SpaceX made a surprise announcement that it would attempt to use a high-speed boat and large net to catch part of rocket. And it worked after a failed first attempt.

Google today announced a pair of new artificial intelligence experiments from its research division that let web users dabble in semantics and natural language processing. For Google, a company that’s primary product is a search engine that traffics mostly in text, these advances in AI are integral to its business and to its goals of making software that can understand and parse elements of human language.

The website will now house any interactive AI language tools, and Google is calling the collection Semantic Experiences. The primary sub-field of AI it’s showcasing is known as word vectors, a type of natural language understanding that maps “semantically similar phrases to nearby points based on equivalence, similarity or relatedness of ideas and language.” It’s a way to “enable algorithms to learn about the relationships between words, based on examples of actual language usage,” says Ray Kurzweil, notable futurist and director of engineering at Google Research, and product manager Rachel Bernstein in a blog post. Google has published its work on the topic in a paper here, and it’s also made a pre-trained module available on its TensorFlow platform for other researchers to experiment with.

The first of the two publicly available experiments released today is called Talk to Books, and it quite literally lets you converse with a machine learning-trained algorithm that surfaces answers to questions with relevant passages from human-written text. As described by Kurzweil and Bernstein, Talk to Books lets you “make a statement or ask a question, and the tool finds sentences in books that respond, with no dependence on keyword matching.” The duo add that, “In a sense you are talking to the books, getting responses which can help you determine if you’re interested in reading them or not.”

Skyscrapers shoot up in most cities, but what are developers to do in growing places where new building construction is limited to less than ten stories tall?

Texas-based NanoRacks is fine-tuning and rebranding its concept for turning upper-stage rocket boosters into orbital outposts, starting with a habitat called Independence-1.

From research labs to factories, farms, and even our own homes, robots are everywhere these days. But which are the most important robots ever built? We decided to welcome our new robot overlords with just such a list. Read on to discover which robots we owe a debt of a gratitude for their part in turning science fiction into, well, science.

SpotMini attends MIT 6.S099: Artificial General Intelligence https://agi.mit.edu Thanks to our friend from Boston Dynamics for the visit. Notes: There’s no audio. SpotMini’s movements are not sped up. All were performed live in front of a packed house of students. It was amazing to witness in person.

The plan to launch the module into space, and take reservations from customers for multimillion-dollar trips, was announced today at the Space 2.0 Summit in San Jose, Calif.

Orion Span says its hotel habitat, dubbed Aurora Station, will be about the size of a large private jet’s cabin, with 5,650 cubic feet of pressurized space. It’ll accommodate up to six residents at a time, including two professional crew members.

Tiangong 1, China’s fallen space station, is now in pieces somewhere on the floor of the Pacific Ocean, but it’s hardly the last spacecraft that will plunge to earth. In fact, by the end of the week, three more are expected to re-enter the atmosphere.

Two pieces of space junk from Kazakhstan and one from India are headed home, part of the surprisingly regular amount of cosmic debris that falls to earth each year. The first could occur as early as tomorrow evening, according to Satview.org.

PSLV R/B, an Indian spacecraft that was launched Nov. 4, 2013, is expected to reenter the atmosphere at approximately 6:30 p.m. ET Tuesday. That will be followed Wednesday at 7:30 p, m, ET by FLOCK 2E-3, a Kazakh spacecraft that has been orbiting earth since Nov. 19, 1998. Finally, Friday morning at approximately 10:24 a.m. ET, FLOCK 2E’-6, another Kazakh orbital will fall to earth.
