A new robot bug that can live in the ocean for 100 years and feed off of bacteria has made its debut as DARPA’s latest surveillance tool.

With a vast amount of area to cover, the US government is funding research for new oceanic spy technology. Now, a Binghamton University team has developed what may become one of the most simple and effective tools in its arsenal.

Now, a new DARPA initiative is playing off of the idea of “the Internet of Things,” the term used for the many non-computer devices connected to the Internet in some way, from refrigerators to fish tanks, and seeking to develop an “Ocean of Things.” With many futurists’ eyes on space conflict and satellite warfare, it’s easy to forget that 71% of the Earth’s surface is water, and naval conflict is still an element in geopolitics.

The transport sector is a significant contributor to greenhouse gas emissions in Hong Kong, accounting for 19% of total emissions. Supporting the development of green transport can help reduce air pollutant emissions. The Hong Kong Polytechnic University (PolyU) is committed to promoting research into green technologies to support Hong Kong’s goal of reducing the City’s total carbon emissions from the 2005 level by half before 2035 and achieving carbon neutrality before 2050.

A research team led by Prof. Eric Cheng, Professor of the Department of Electrical and Electronic Engineering at PolyU, received support from the “Innovation and Technology Support Program (Mid-stream, theme-based)” last June for the research project “Smart Refrigeration Truck Development Program—Power, Solar and Intelligence Method for Logistics and Storage.” The project is aimed at promoting the transformation of freezer trucks from traditional fuel driven freezer system to smart electric driven and strengthening the wider adoption of solar energy.

After one year, the PolyU team has successfully developed a novel freezer truck that supports a solar-powered freezer system and features vehicle-connected power storage and sharing technology. The project has received staunch support from the government, academia and industry, including from Sunlight Eco-tech Limited, Advanced Sunlight Pty Limited from Australia, and the Electrical and Mechanical Services Department.

Looking like a set of bridge supports that were accidentally installed on a cargo ship, a new wind-driven system by startup CoFlow Jet promises to reduce ship fuel costs by up to 90% using stationary cylinders with no moving parts.

Between rising fuel costs and increasing government mandates requiring shipping companies to go carbon neutral by 2050, there’s a strong push to increase the efficiency of cargo ships while reducing their emissions. One way of doing this is to take a page from the history books and readopt sails to harness the wind.

On the surface, that makes sense. Sails have been propelling ships all over the world for millennia and were still used for commercial transport until after the Second World War. However, there are two problems with sails that have pushed them out of the cargo market for all except the most local of niches.

Australian businesses are paying untold amounts of ransom to hackers, but the government is hoping to claw back some visibility with a landmark cybersecurity law.

While major ransomware attacks on companies such as MediSecure, Optus and Latitude have grabbed headlines for breaching the privacy of millions, the practice of quietly paying off cybercriminals has flourished in the dark.

The situation has deteriorated to the point that the government’s original ambition for an outright ban on ransom payments has been nixed, for now, and the focus has shifted to mapping the scale of the problem.

These advancements in AI technologies are happening in China despite the stringent measures that the U.S. is placing against its technological ambitions. The bans and embargoes on high-end chips Washington has placed on Beijing meant that Chinese companies have difficulty sourcing Nvidia’s latest, most potent AI processors. While China is hard at work trying to catch up on the hardware side of things, many experts believe it’s still at least a decade away from achieving parity with the United States.

It’s evident, though, that Chinese tech firms can catch up on the software side despite the hardware bans. Nevertheless, the White House wants to change that with a bill in the U.S. Congress that would give the American government more control over limiting the export of American AI code. Some parties are trying to limit the development of open-source AI tech to stop Chinese companies from using it, but doing so might do more harm than good for the U.S.

Clément Delangue, the CEO of Hugging Face, a firm that lets its users share its open-source AI projects, said, “Open-source AI is the foundation of AI development,” referring to how the collaboration of researchers and organizations in the U.S. allowed it to become the world leader in AI, “and it looks like China could do the same thing.”

In the ongoing fight against climate change, is it better to plant trees or allow nature to do it for us? This is what a recent study published in Nature Climate Change as a team of international researchers investigated the cost-effectiveness of reforestation for mitigating the effects of climate change, specifically regarding whether planting trees or natural reforestation are appropriate measures for this effort. This study holds the potential to help scientists, conservationists, and the public better understand the steps that can be taken to mitigate the effects of climate change, for both the short and long term.

“Trees can play a role in climate change mitigation, for multiple reasons,” said Dr. Jacob Bukoski, who is an Assistant Professor in the Oregon State University College of Forestry and a co-author on the study. “It’s pretty easy to understand that forests pull carbon dioxide from the atmosphere and store it, and trees are something pretty much everyone can get behind – we have seen multiple bipartisan acts for tree planting introduced in Congress. This study brings a nuanced perspective to the whole ‘should we plant trees to solve climate change’ debate.”

The challenges posed by solar and wind generators are real. They are inherently variable, producing electricity only when the sun is shining and the wind is blowing. To ensure reliable energy supplies, grids dominated by renewables need “firming” capacity: back-up technology that can supply electricity on demand.

Some, including the Albanese government, argue gas-fired generators are needed to fill the gap. Others, such as the Coalition, say renewables can’t “keep the lights on” at all and Australia should pursue nuclear energy instead.

But a new way to firm up the world’s electricity grids is fast developing: sodium-ion batteries. This emerging energy storage technology could be a game-changer – enabling our grids to run on 100% renewables.

A study of 17 commonly used synthetic ‘forever chemicals’ has shown that these toxic substances can readily be absorbed through human skin.

New research, published today in Environment International proves for the first time that a wide range of PFAS (perfluoroalkyl substances) — chemicals which do not break down in nature – can permeate the skin barrier and reach the body’s bloodstream.

PFAS are used widely in industries and consumer products from school uniforms to personal care products because of their water and stain repellent properties. While some substances have been banned by government regulation, others are still widely used and their toxic effects have not yet been fully investigated.
