Asteroid Impacts Increased Around Time of Largest Extinction Event

Posted by in categories: asteroid/comet impacts, existential risks

Dinosaurs never stood a chance once asteroid impacts more than doubled some 290 million years ago.

By studying the Moon, an international team of scientists revealed that the number of asteroids crashing into Earth and its satellite increased by two to three times toward the end of the Paleozoic era.

Contrary to popular belief, most of the planet’s more primitive asteroid-produced craters were not erased by erosion and other geologic processes.

Announcing Hyperledger Grid, a new project to help build and deliver supply chain solutions!

Posted by in categories: bitcoin, computing, cryptocurrencies

While I’m not a big supporter of cryptocurrency, I am a supporter of utilizing blockchain technology in other areas. For example. logistics. The Linux Foundation announced the creation of the Hyperledger Grid project just for that purpose. However, as they state, this isn’t a software project, but a platform project.


Supply chain is commonly cited as one of the most promising distributed ledger use-cases. Initiatives focused on building supply chain solutions will benefit from shared, reusable tools. Hyperledger Grid seeks to assemble these shared capabilities in order to accelerate the development of ledger-based solutions for all types of cross-industry supply chain scenarios.

Grid intends to:

An Appointment with Death

Posted by in category: life extension

The intercom in Death’s office buzzes. With a slightly frustrated sigh, Death lifts his skeletal head from the newspapers he was reading, takes a puff of his cigar, stretches out a little, and presses a button on the intercom.

— I swear, all this work is going to kill me one day. I said I didn’t want to be interrupted, Miss Coffins; what is it?

— I’m sorry, Mr. Death, but Mr. Aging insists that he needs to see you right now. He says it’s urgent.

Scientists turn carbon emissions into usable energy

Posted by in categories: climatology, engineering, sustainability

MAJOR BREAKTHROUGH: A recent study affiliated with UNIST has developed a system that produces electricity and hydrogen (H2) while eliminating carbon dioxide (CO2), the main contributor of global warming. This breakthrough has been led by Professor Guntae Kim in the School of Energy and Chemical Engineering at UNIST in collaboration with Professor Jaephil Cho in the Department of Energy Engineering and Professor Meilin Liu in the School of Materials Science and Engineering at Georgia Institute of Technology.

In this work, the research team presented a hybrid Na-CO2 system that can continuously produce electrical and hydrogen through efficient CO2 conversion with stable operation for over 1,000 hours from spontaneous CO2 dissolution in aqueous solution.

“Carbon capture, utilization, and sequestration (CCUS) technologies have recently received a great deal of attention for providing a pathway in dealing with global climate change,” says Professor Kim. “The key to that technology is the easy conversion of chemically stable CO2 molecules to other materials.” He adds, “Our new system has solved this problem with CO2 dissolution mechanism.”
