'Grounding zone' of Antarctica's 'doomsday' Thwaites glacier is revealed in first ever footage

Daily Mail - Science & tech

First ever footage of the underside of the'doomsday' Thwaites glacier has been sent back by a robotic yellow submarine dubbed Icefin. Glaciologists have likened the groundbreaking images and video to the first steps on the moon taken by Neil Armstrong in 1969. Early analysis reveals that turbulent warm waters underneath the ice sheet, which is the same size as Britain, are causing an'unstoppable retreat'. Experts have previously predicted that if Thwaites was to melt completely, it would lead to a significant increase in worldwide sea levels of around two feet (65cm). The impact on coastal communities around the world would be catastrophic.


Scientists turn ALBATROSSES into surveillance drones to help track illegal fishing boats

Daily Mail - Science & tech

A team of researchers from the University of La Rochelle in France have converted albatrosses into de facto surveillance drones as part of a project to gather data on illegal fishing boats in the South Pacific and Indian Ocean. The team traveled to popular albatross nesting locations at Amsterdam Island and Kerguelen Island in the Indian Ocean north of Antarctica, and attached small sensors to 169 albatrosses in a procedure that took about 10 minutes per bird. The sensors weigh 65 grams, or around a seventh of a pound, and were equipped with a GPS receiver, a radar antenna, and a satellite communications monitor to track various boat communication systems. The devices were each powered by a small lithium battery that maintains a charge through a small solar panel, according to a report from ArsTechnica. The albatrosses covered more than 18 million square miles between East Africa and New Zealand, gathering data from more than 600,000 GPS locations.


Robot kayaks found the basin of an Alaskan glacier is melting 100 TIMES faster than models showed

Daily Mail - Science & tech

Seaborne robots have made a startling discovery beneath a 20-mile glacier in Alaska. The technology found the massive rivers of ice may be melting under the LeConte Glacier much faster than previously thought. Scientists programmed autonomous kayaks to swim near the icy cliffs of the glacier to measure the'ambient meltwater intrusions', which shows how much fresh water is flowing into the ocean from underneath the glacier. The study found ambient melting was 100 times higher than models had estimated. This is the first time experts have been able to analyze plumes of meltwater - the water released when snow or ice melts, where glaciers meet the ocean- because the feat is far too dangerous for ships due to falling ice of slabs from the glacier.


Measuring Diversity of Artificial Intelligence Conferences

arXiv.org Artificial Intelligence

The lack of diversity of the Artificial Intelligence (AI) field is nowadays a concern, and several initiatives such as funding schemes and mentoring programs have been designed to fight against it. However, there is no indication on how these initiatives actually impact AI diversity in the short and long term. This work studies the concept of diversity in this particular context and proposes a small set of diversity indicators (i.e. indexes) of AI scientific events. These indicators are designed to quantify the lack of diversity of the AI field and monitor its evolution. We consider diversity in terms of gender, geographical location and business (understood as the presence of academia versus industry). We compute these indicators for the different communities of a conference: authors, keynote speakers and organizing committee. From these components we compute a summarized diversity indicator for each AI event. We evaluate the proposed indexes for a set of recent major AI conferences and we discuss their values and limitations.


Negative Statements Considered Useful

arXiv.org Artificial Intelligence

Knowledge bases (KBs), pragmatic collections of knowledge about notable entities, are an important asset in applications such as search, question answering and dialogue. Rooted in a long tradition in knowledge representation, all popular KBs only store positive information, while they abstain from taking any stance towards statements not contained in them. In this paper, we make the case for explicitly stating interesting statements which are not true. Negative statements would be important to overcome current limitations of question answering, yet due to their potential abundance, any effort towards compiling them needs a tight coupling with ranking. We introduce two approaches towards compiling negative statements. (i) In peer-based statistical inferences, we compare entities with highly related entities in order to derive potential negative statements, which we then rank using supervised and unsupervised features. (ii) In query-log-based text extraction, we use a pattern-based approach for harvesting search engine query logs. Experimental results show that both approaches hold promising and complementary potential. Along with this paper, we publish the first datasets on interesting negative information, containing over 1.1M statements for 100K popular Wikidata entities.


An emotionally intelligent AI could support astronauts on a trip to Mars

And in just a few years, Akin hopes to see Fiona the Future come to life. Fiona wouldn't even necessarily be a physical robot, but rather a cross-platform system running on a spacecraft like Gateway (NASA's upcoming lunar space station), or a habitat on the moon or Mars. There's no commitment yet for this to be part of Artemis or Gateway, but the company is working actively with other players in the space industry to ink some sort of initiative. Yearsley says any hope of making Fiona a part of Gateway or Artemis means Akin must have reliable prototypes out by September. Should that fail, Akin will see if its AI can be tested in more isolated settings, like Antarctica, or in different contexts, such as assisting elderly or disabled people.


Invitation to our next D-Flect with Dr. Shama Rahman

#artificialintelligence

We speak a good deal on AI and creativity, most frequently around AI being creative; what about enhancing human creativity using AI? Our speaker โ€“ Dr Shama Rahman โ€“ will give us insight into the neuroscience of creativity and demonstrate how AI can be used as a tool to spark human creativity. She will explore the potential of the complementary symbiosis of neuroscientific-knowledge and AI-capabilities to result in neuro-enhancement and'augmented creative intelligence'; we can all benefit from this approach. Expounding on the stages within an innovation framework, different types of creativity, and the underlying neuroscience of the creative process, Shama will explore the capacity of AI as a symbiotic tool to augment the human creative process. The participants in this event can expect to embark on an AI-assisted creative session themselves using the'FlowCreate Innovator' which enhances creative processes combining AI, neuroscience, and digitised design-thinking tools and innovation frameworks: everyone attending will get a link to a trial version of the FlowCreate Innovator platform Dr Shama Rahman is a scientist, artist, creative technologist and futurist.


Antarctic waters: Warmer with more acidity and less oxygen

#artificialintelligence

The increased freshwater from melting Antarctic ice sheets plus increased wind has reduced the amount of oxygen in the Southern Ocean and made it more acidic and warmer, according to new research led by University of Arizona geoscientists. The researchers found Southern Ocean waters had changed by comparing shipboard measurements taken from 1990 to 2004 with measurements taken by a fleet of microsensor-equipped robot floats from 2012 to 2019. The observed oxygen loss and warming around the Antarctic coast is much larger than predicted by a climate model, which could have implications for predictions of ice melt. The discovery drove the research team to improve current climate change computer models to better reflect the environmental changes around Antarctica. "It's the first time we've been able to reproduce the new changes in the Southern Ocean with an Earth system model," said co-author Joellen Russell, a professor of geosciences. The research is the first to incorporate the Southern Ocean's increased freshwater plus additional wind into a climate change model, she said.

Drones show how Greenland Ice Sheet fractures causing dramatic waterfall and rising sea levels

Daily Mail - Science & tech

Captivating images capture by custom-built drones have revealed the damage to the Greenland Ice Sheet that is being caused by rising global temperatures. The images, which have been taken as part of an EU-funded project to track changes in the world's second-largest ice sheet, are the first drone-based observations of how fractures form and expand under meltwater lakes. The expanding fractures cause catastrophic lake drainages, during which huge quantities of water are transferred to below the surface of the ice. Changes in ice flow occur on a much shorter timescales than were previously considered possible, said the research team, which was led by the University of Cambridge. 'It's possible we've under-estimated the effects of these glaciers on the overall instability of the Greenland Ice Sheet,' said drone pilot Tom Chudley, a PhD student at the University of Cambridge's Scott Polar Research Institute.
