What has changed since “Pale Blue Dot”?
Posted by Philip Raymond in categories: astronomy, cosmology, environmental, ethics, habitats, lifeboat, science, space, space travel, sustainability
I am not an astronomer or astrophysicist. I have never worked for NASA or JPL. But, during my graduate year at Cornell University, I was short on cross-discipline credits, and so I signed up for Carl Sagan’s popular introductory course, Astronomy 101. I was also an amateur photographer, occasionally freelancing for local media—and so the photos shown here, are my own.
By the end of the 70’s, Sagan’s star was high and continuing to rise. He was a staple on the Tonight Show with Johnny Carson, producer and host of the PBS TV series, Cosmos, and he had just written Dragons of Eden, which won him a Pulitzer Prize. He also wrote Contact, which became a blockbuster movie, starring Jodie Foster.
Sagan died in 1996, after three bone marrow transplants to compensate for an inability to produce blood cells. Two years earlier, Sagan wrote a book and narrated a film based on a photo taken from space.

Quantum physicists turn to the dark state
Posted by Andreas Matt in categories: computing, quantum physics, transportation
“Suppose you want to travel from Helsinki to New York and you have to change your flight in London,” explains Sorin Paraoanu. “Normally you would first fly on a plane from Helsinki to London, then wait for some time in the airport in London, then board the flight London-New York. But in the quantum world, you would be better off boarding a plane from Helsinki to London sometime after the flight London-New York took off. You will not spend any time in London and you will arrive in New York right at the time when the plane from Hesinki lands in London.” This is mind-boggling but the experiment shows that it is indeed happening.
Besides the relevance for quantum computing, the result also has deep conceptual implications. Much of our understanding of the reality is based on the so-called continuity principle: the idea that influences propagate from here to there by going through all the places in-between. Real objects don’t just appear somewhere from nothing. But the experiment seems to defy this. Like in a great show of magic, quantum physics allows things to materialize here and there, apparently out of nowhere.
The team would like to acknowledge the excellent scientific environment created in the Low Temperature Laboratory (part of OtaNano) at the Department of Applied Physics.

Access denied: Mad Kim Jong-un’s cyber war with West FOILED

For now he remains hands off; however, once China rolls out their Quantum infrastructure; then what?
NORTH Korea’s bid to wreak havoc in the West with an army of computer nerds has been dealt a crushing blow.

Ireland can become global cyber security hub — study
Posted by Karen Hurst in categories: business, cybercrime/malcode
Ireland has real opportunity to benefit from increased global investment and establish itself as a world-class hub for cyber security practices, solutions and investment, according to a new report from Deloitte. Conducted in association with the International Sustainability and Investment Centre, the report found that Ireland has proven itself to be an innovative centre for technology and has the potential to become a world leader in cyber security.
Respondents to a survey for this report identified increased regulation on data privacy (73%), more sophisticated scamming and phishing (59%), and growth in identity theft (53%) as the major trends in the cyber area over the next five years. This will force businesses to change how they organise and manage their data security.
More than one third (36%) of respondents believe there will a trend towards outsourcing cyber management to third party organisations, and 27 percent think that businesses will establish global/regional centres of excellence for managing this function. The implication of this will be that a small number of locations will be preferred for basing these centres of excellence.

Cyber Security: How to Protect Your Firm and its Clients
Posted by Karen Hurst in categories: biotech/medical, cybercrime/malcode, law
Law Firms are prime targets for hackers.
Law firms are considered by many hackers to be soft targets with a wealth of valuable information. Data from social security numbers, credit cards, and client confidences is enough to make the criminal mind salivate with malicious intent. Between 31–45% and 10–20% of firms have been infected by spyware or experienced security breaches respectively. But what can a private practitioner or law firm do to prevent these trespasses on their networks?

Military-Funded Study Predicts Twitter Uprisings
Posted by Karen Hurst in categories: biotech/medical, government, military, mobile phones, robotics/AI
I must admit that appears that almost anything in tech is being called out as a threat. FB, Twitter, Smartphones, CRISPR, AI, etc. Tech advancements do bring greater freedoms & opportunities to express one’s ideas and beliefs as well as enable a greater access to people, information, and geographical locations; however, and that does pose some level of risk in small pockets of the greater poulation. Nonetheless, I hope that the government spying pendullum swing doesn’t go overboard.
Who tweets at you, what you tweet back, and why can predict your next protest act on social media.

Quantum dot solids: This generation’s silicon wafer?
Posted by Karen Hurst in categories: electronics, engineering, quantum physics, solar power, sustainability
Just as the single-crystal silicon wafer forever changed the nature of electronics 60 years ago, a group of Cornell researchers is hoping its work with quantum dot solids – crystals made out of crystals – can help usher in a new era in electronics.
The multidisciplinary team, led by Tobias Hanrath, associate professor in the Robert Frederick Smith School of Chemical and Biomolecular Engineering, and graduate student Kevin Whitham, has fashioned two-dimensional superstructures out of single-crystal building blocks. Through directed assembly and attachment processes, the lead selenide quantum dots are synthesized into larger crystals, then fused together to form atomically coherent square superlattices.

Portland firm DARPA research could make disputes like Apple v FBI obsolete
Posted by Karen Hurst in categories: computing, privacy
Portland computer science research company Galois snagged a $6.2 million grant from the Department of Defense for a project that, if successful, could make the current battle between the FBI and tech giant Apple obsolete.
The three-year research contract comes from the Defense Advanced Research Projects Agency and will fund research into quantifying privacy preservation systems.
‘Can you quantify how private a system is or isn’t and can you make a judgment about it,’ said Galois CEO Rob Wiltbank,…

Personally, I thought they already had one.
