A new program directed by researchers at Queensland University of Technology (QUT) is calling on citizen scientists to help experts collect and categorise data to better monitor the Great Barrier Reef.

The Virtual Reef Diver project is the second phase in a larger scheme to collect more data than researchers can alone.

Phase one invites people to log on and examine photos, looking for important features such as coral, algae and fish.

Phase two asks anyone visiting the reef to add to the database by taking a photo of the reef and uploading to the virtual reef website.

By partnering with the public to collect and analyse data, researchers are better able to understand the health of the 348,700 square kilometre reef.

Project leader Erin Peterson says that the Great Barrier Reef is “simply too big for scientists and researchers to monitor it alone”.

“Many of those people who are out on the reef are already taking underwater images. We want them to share that knowledge by uploading their images of the seafloor to the Virtual Reef Diver website.”

The research team hopes to specifically gather information about the location and amount of hard coral as an indicator of reef health.

The website provides guidelines for how to best capture images for analysis, and notes that citizen scientists can use their point-and-shoot or smartphone cameras.

They further advise participants to photograph a one-meter square patch looking straight down at the seafloor, rather than at an angle.

This project is ongoing, and anyone can create an account to observe and categorise existing photos in the database.

Virtual Reef Diver is the result of the collaboration of QUT, the Australian Broadcasting Company (ABC) and Australian Research Council Centre of Excellence for Mathematical and Statistical Frontiers (ACEMS).

Nobel laureate Rainer Weiss will be a guest at the Australian Institute of Physics (AIP) Congress, which will run between December 9 and 13 in Perth, Australia.

The event is billed as “a magnificent week of world-class science” and will be held at the University of Western Australia Crawley Campus.

Weiss won the Nobel Prize in Physics in 2017 “for decisive contributions to the LIGO detector and the observation of gravitational waves”.

He was awarded half the prize, with the other half shared by physicists Kip Thorne and Barry Barish.

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is located in Louisiana and Washington State in the US, and the two centres are calibrated to jointly collect data on gravitational waves.

Construction on LIGO began in 1994, with main observations beginning after 20 years of construction, expansion, and piloting.

In September 2014, the facility detected gravitational waves from two black holes which were converging more than 1.3 billion light years from Earth.

Weiss is now Professor Emeritus at the Massachusetts Institute of Technology (MIT) in Cambridge Massachusetts, and an adjunct professor at Louisiana State University (LSU) in Louisiana.

Along with the Nobel, he has won numerous international awards including an MIT excellence in teaching award and the John Simon Guggenheim Memorial Foundation Fellowship.

He is a member of the National Academy of Sciences and has served on committees such as the Committee on NASA Astrophysics Performance Assessment and the Panel on Particle, Nuclear, and Gravitational-wave Astrophysics.

The AIP Congress will be staged jointly with the Australian Optical Society (AOS) Conference, the Australian Conference on Optical Fibre Technology (ACOFT), and the 2018 Conference on Optoelectronic and Microelectronic Materials and Devices (COMMAND 2018).

Other keynote speakers include Julia Yeomans from the University of Oxford in the UK, Michael Wiescher from the University of Notre Dame in...

The first ever Australia New Zealand Biochar Study Tour will visit several cities across South Australia and Victoria, Australia, next year.

The tour will be an addition to the third Australia New Zealand Biochar Conference (ANZBC19), scheduled to run between October 20 and 26, 2019.

Biochar refers to the use of charcoal as an additive in soil with the aim of improving the quality of soil, especially for farming.

It has been suggested that this may facilitate carbon sequestration, or the removal of carbon from the atmosphere to be stored indefinitely in solid matter.

The Australia New Zealand Biochar Initiative website says, “the objective of ANZBC19 is to focus on mainstreaming biochar by bringing together stakeholders who wish to achieve commercial scale biochar outcomes with significant economic, environmental and community benefits”.

The tour is aimed at people who might apply these products to their work, such as farmers, horticulturists, and foresters.

Over three days, presenters will take to Mt. Gambier and Tantanoola in South Australia, and Portland in Victoria to discuss practical application and development in the field.

This will be followed by a conference hosted by the Royal Melbourne Institute of Technology, also known as RMIT University, at its Melbourne city campus.

Keynote presenters include Tom Miles and Genxing Pan. Miles is chair of the International Biochar Initiative and works in Oregon in the US, designing systems in biomass processing for things such as power generation and nutrient management. Pan is a soil scientist developing enhanced biochar fertilisers at Nanjing Agricultural University in Jiangsu province, China.

The conference will include presentations from researchers, engineers, and manufacturers among others. The final day of the conference will consist of a field trip around the Melbourne metropolitan area to visit processing and manufacturing sites.

The conference is sponsored by RMIT University and commercial biochar...

The ethical dilemmas inherent in artificial intelligence (AI) will be the focus of a seminar held at the State Library Victoria, in Melbourne, Australia on 13 November.

Professors Toby Walsh and Sharon Oviatt will sit down to discuss and answer questions about the future of this technology in a forum to be moderated by Kylie Ahern, co-founder of Cosmos magazine.

The event is billed as “The ethical dilemmas of AI – Are we sleepwalking into an AI future” and is open to the public. Register for the event here.

Sharon Oviatt is a professor at Monash University, known for her work in human-computer interaction. Toby Walsh is a professor at the University of New South Wales in Australia, with a focus on limiting AI “to ensure the public good”.

Registration opens at 5:30pm, with a panel discussion at 6:15pm and networking drinks to follow.

Ahern says the event is open to “anyone with an interest in AI”.

“This talk will help people think bigger about AI and gain a better understanding of what it is and how it might impact us,” she adds.

The panellists are expected to discuss Australia’s investment in the field, the development of commercialised technology and use of this technology to support human needs, activities and values.

Ahern says she plans to ask the panellists about the most impactful and innovative research projects in the field today, as well as questions related to the timeframe for wide-spread AI in our daily lives.

“Outside of academia we don’t have a great understanding of AI, the history of AI research or where it’s headed,” she says.

“What should we be scared of and excited about? What are the safety measures we need to implement? How will it change us and how our behaviours?”

The event Is part of the Monash University Dean’s Seminar Series.

A new podcast from the NASA Jet Propulsion Laboratory (JPL) in California gives listeners a behind the scenes look at the most recent mission to Mars.

The eight-episode series is titled “On a Mission” and will be airing throughout November, outlining the Mars InSight Lander mission, which launched in May 2018 and is expected to land on the planet in late November.

Host Leslie Mullen is a science journalist who interviews members of the InSight team during each brilliantly produced 20-to-30-minute episode.

The first two episodes outline the history of the mission and the difficulties the lander will face as it attempts to touch down at its designated landing site, Elysium Planitia.

Once it has done so, it will need to rest and remain undisturbed by dust or wind in order to operate. Its primary mission will be to collect data from beneath the surface, including the first measurements of seismic activity on Mars.

One of the key concerns for the InSight team is about dust the craft may face while landing. The engineers at NASA JPL added an additional protective coating to the heat shield to protect it as it enters the atmosphere at more than 12,000 kilometres per hour.

Using a mathematical approach known as Monte Carlo simulations, the team gambles with randomised landing parameters, such as mass, rocket efficiency, flight path angle, and location. In the five years leading up to launch, as many as one million scenarios were simulated.

Planet-wide dust storms are of one such condition for which the team has been planning. These forced the Opportunity Rover into remain in a sleep state since May of this year. The podcast reveals that each morning, the team at NASA JPL start the day by playing a song from their “Wake Up” playlist, which includes delights as diverse as Wham!, the Beatles and Iron Maiden.

The podcasts can be accessed here.

British astrophysicist and Oxford University visiting professor Jocelyn Bell Burnell is set to talk about her extraordinary career in a live webcast on Thursday, October 25, at 7pm US eastern time (10am Friday, October 26, on east coast Australia).

Burnell is best known for her leading role in 1967 in the discovery of pulsars – a breakthrough widely considered one of the most important scientific advances of the twentieth century.

The achievement led in 1974 to the awarding of a Nobel Prize – not to her, but to her graduate advisor, a scandal still noted, and still uncorrected, today.

Her subsequent career, however, has been every bit as stellar as her early days, and this year she has been awarded the Special Breakthrough Prize in Fundamental Physics, not only for her work on pulsars but also for a lifetime spent inspiring others.

The prize is worth $US3 million – a haul she plans to donate entirely to programs aimed at fostering young scientists.

She will officially receive the award at a glittering ceremony to be held on November 4 at the NASA Ames Research Centre in Silicon Valley, US, hosted by actor Pierce Brosnan.

Before that, however, she will deliver a live talk at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, in Canada, webcast for people in other parts of the world. The title of her talk is: “What is that?!” The Discovery of Pulsars: A Grad Student’s Story.

The webcast can be found here when it starts.

Divers at the University of Queensland in Australia will spend 24 hours under water in an effort to raise money and awareness for coral reefs.

The event, called For the Love of the Reef, is part of the not-for-profit Reef Citizen Science Alliance’s month-long campaign to educate the community and take action to support coral reef sustainability efforts.

A total of 48 divers from the university’s underwater club, UniDive, will take turns diving in pairs at the UQ Sport Aquatic Centre beginning at 9am on Saturday, October 20.

While underwater they will practice the surveying skills which they might use if diving around actual coral reefs. The team, lead by senior research fellow Chris Roelfsema, will coordinate events throughout the day to raise money and awareness about the reef.

According to Roelfsema, “25% of marine creatures originated from, or are depending on, coral reefs, but coral reefs only cover one percent of the ocean floor.

“These regions have the highest biodiversity in the oceans - similar to rainforests on land - and also protect us from weather events.”

He notes the difficulty in raising awareness about coral reefs, saying “a lot of people simply don’t know these facts, and how can you love and protect something if you don’t know enough about it? We are hoping that this event can play its part in changing that”.

The event includes a barbecue and prize raffle, and visitors can participate in activities such as a virtual reef exploration, an underwater rugby demonstration, reef art activities, and a nighttime screening of Lin Sutherland’s film, Beauty and the Reef.

Funds raised will be donated to environmental groups CoralWatch, Reef Check Australia, and Virtual Reef Diver.

The diving marathon is billed as ‘fun for all ages’. Registration details and a full program for the day’s events can be found here.

Light Up, a design for an energy efficient adaptation of the Melbourne suburb of St Kilda, by NH Architecture. 

LAGI

Is this the aesthetic face of our energy future?

The sparkling canopy draped along the beach from the roof of the Palais Theatre in Melbourne, Australia, won local firm NH Architecture first prize in the Australian leg of this year’s Land Art Generator Initiative (LAGI).

Called Light Up, the design incorporates solar, wind, tensional energy and microbial fuel cell technologies that could generate 2220 megawatt-hours per year, enough to power 500 homes. Old car batteries repurposed as handrails along the paths could store energy for 24/7 access.

Second prize went to Night and Day, by Olson Kundig from Seattle in the US. The pedestrian bridge linking the esplanade to the sea in the beachside suburb of St Kilda combines solar energy with a hydro battery to generate 1000 MWh per year.

The inner-workings of the system are on show as the solar sail and water vessel, suspended above the walkway, pumps and releases water to create electricity.

The US-based LAGI provides a platform for artists, architects and other creatives to work with engineers and scientists to propose innovative and aesthetic ways to create sustainable energy infrastructure that is also public art.

The competition is held in cities around the world every two years. The 2018 Australian competition, which is sponsored by the government of the state of Victoria, attracted hundreds of entries.
