Oceanographers select Wave Glider ocean robot for scientific research

by

Top oceanographers have selected Wave Gliders, the most experienced, long duration ocean robots, as their sensor platform to conduct advanced scientific research in the most inhospitable and remote regions of the Arctic and Southern Oceans.

The US scientists, from Scripps Institution of Oceanography (Scripps) and the Applied Physics Laboratory of the University of Washington (APL-UW), will integrate sophisticated oceanographic and atmospheric sensors onto the Wave Gliders to measure extreme wave states, winds, temperature, and salinity in the upper layers of the ocean.

Historically, these regions have been under-sampled due to the dangers and risks of operating in these turbulent oceans.

Apple partners on carbon-free aluminium smelting method

by

Aluminium giants Alcoa Corporation and Rio Tinto Aluminium have announced a joint venture to commercialise patented technology that eliminates direct greenhouse gas emissions from the traditional smelting process, a key step in aluminium production.

This is a revolutionary advancement in the manufacturing of one of the world’s most widely used metals.

Apple helped accelerate the development of this technology has partnered with both aluminium companies, and the Governments of Canada and Quebec, to collectively invest a combined $144 million to future research and development.

Construction starts at the world’s largest hydrogen pilot plant

by

An EU-funded flagship project, the H2FUTURE project consortium, has officially given the go-ahead for construction of the world’s largest pilot plant for the production of “green” hydrogen at the Voestalpine site in Linz, Austria.

With a capacity of 6 megawatts, this is the most effective and advanced plant of its type. It is scheduled to be fully operational by spring 2019.

The partners,  consisting of Voestalpine, Siemens, Verbund, and Austrian Power Grid, together with the research partners K1-MET and ECN, will use this facility to research into future breakthrough technologies which are needed for a CO2-reduced energy future and the decarbonization of steel production to meet global climate goals over the long-term.

Swiss students through to finals of Elon Musk’s Hyperloop competition

by

ETH Zurich students are through to the next round of US entrepreneur Elon Musk’s SpaceX Hyperloop competition in Summer 2018 with their ‘Swissloop’ concept, against thousands of other teams.

Hyperloop is about moving pods through a vacuumed-sealed tube, transferring the tubular mail idea to passenger transport as a precursor to fast travel, and the competition is to design the best system.

The Hyperloop concept is based on vacuum technology: the vacuum tunnel massively reduces air resistance and thus enables smooth driving at speeds of up to 1,000 kilometers per hour.

Energy-harvesting power cells set to solve IoT sensor battery problem

by

A solution could be at hand for a technology barrier that experts say has been the primary problem limiting the growth of the Internet of Things (IoT): the need to provide batteries for IoT sensors.

The solution is a patented energy-harvesting technology – the Evercell power cell – that is capable of powering wireless IoT sensors without batteries.

BRIDG, an industry-led public-private partnership for advanced technologies and manufacturing processes, is collaborating with Face International Corporation in the development and integration of the power cell.

Microsoft and partners lay superfast subsea cable across Atlantic

by

 

There’s not many things more fascinating in today’s high-tech world than subsea cables.

In and of themselves, in principle, they’re just cables. But also in and of themselves they are highly sophisticated and powerful pieces of equipment.

And the sheer magnitude of the engineering involved in laying them undersea across oceans and connecting continents is arguably a wonder of the modern world.  [Read more…] about Microsoft and partners lay superfast subsea cable across Atlantic

Sugar’s ‘tipping point’ link to Alzheimer’s disease revealed

by

sugar cubes

For the first time a “tipping point” molecular link between the blood sugar glucose and Alzheimer’s disease has been established by scientists, who have shown that excess glucose damages a vital enzyme involved with inflammation response to the early stages of Alzheimer’s.

Abnormally high blood sugar levels, or hyperglycaemia, is well-known as a characteristic of diabetes and obesity, but its link to Alzheimer’s disease is less familiar.

Diabetes patients have an increased risk of developing Alzheimer’s disease compared to healthy individuals. In Alzheimer’s disease abnormal proteins aggregate to form plaques and tangles in the brain which progressively damage the brain and lead to severe cognitive decline.

New findings highlight promise of chimeric organisms for science and medicine

by

cell

Rapid advances in the ability to grow cells, tissues and organs of one species within an organism of a different species offer an unprecedented opportunity for tackling longstanding scientific mysteries and addressing pressing human health problems, particularly the need for transplantable organs and tissues.

In a tour de force paper published in the January 26, 2017, issue of the journal Cell, scientists at the Salk Institute report breakthroughs on multiple fronts in the race to integrate stem cells from one species into the early-stage development of another.

Breakthrough by Exeter cell biologists

by

organelles

Scientists have made a breakthrough in understanding how different compartments (or organelles) of human cells interact.

Organelles are the functional units of a cell. Like organs in a body, they perform specialised functions. To allow survival of the cell, organelles have to interact and cooperate. How this is mediated and regulated in the cell is an important and challenging question in cell biology. [Read more…] about Breakthrough by Exeter cell biologists

New model predicts once-mysterious chemical reactions

by

radiation from hydrogen

A team of researchers from Los Alamos National Laboratory and Curtin University in Australia developed a theoretical model to forecast the fundamental chemical reactions involving molecular hydrogen (H2), which after many decades and attempts by scientists had remained largely unpredicted and unsolved

“Chemical reactions are the basis of life so predicting what happens during these reactions is of great importance to science and has major implications in innovation, industry and medicine,” said Mark Zammit, a post-doctorate fellow in the Physics and Chemistry of Materials group at Los Alamos National Laboratory. “Our model is the first to very accurately calculate the probability of fundamental electron-molecular hydrogen reactions.” [Read more…] about New model predicts once-mysterious chemical reactions
