Confirmation of old theory leads to new breakthrough in superconductor science

Posted by in categories: materials, science

Phase transitions occur when a substance changes from a solid, liquid or gaseous state to a different state—like ice melting or vapor condensing. During these phase transitions, there is a point at which the system can display properties of both states of matter simultaneously. A similar effect occurs when normal metals transition into superconductors—characteristics fluctuate and properties expected to belong to one state carry into the other.

Scientists at Harvard have developed a bismuth-based, two-dimensional superconductor that is only one nanometer thick. By studying fluctuations in this ultra-thin material as it transitions into superconductivity, the scientists gained insight into the processes that drive superconductivity more generally. Because they can carry with near-zero resistance, as they are improved, will have applications in virtually any technology that uses electricity.

The Harvard scientists used the new technology to experimentally confirm a 23-year-old theory of superconductors developed by scientist Valerii Vinokur from the U.S. Department of Energy’s (DOE) Argonne National Laboratory.

Jason—a secretive group of Cold War science advisers—is fighting to survive in the 21st century

Posted by in categories: biotech/medical, engineering, government, science

With the end of the Vietnam and Cold wars, Jason members began to branch out from physics and engineering. In 1977, they did their first assessment of global climate models and later advised DOE on which atmospheric measurements were most critical for the models. Since the mid-1990s, Jason has studied biotechnologies, including techniques for detecting biological weapons.


After near-death experience, top scientists seek a long-term home in the U.S. government.

What happened to cognitive science?

Posted by in categories: neuroscience, science

More than a half-century ago, the ‘cognitive revolution’, with the influential tenet ‘cognition is computation’, launched the investigation of the mind through a multidisciplinary endeavour called cognitive science. Despite significant diversity of views regarding its definition and intended scope, this new science, explicitly named in the singular, was meant to have a cohesive subject matter, complementary methods and integrated theories. Multiple signs, however, suggest that over time the prospect of an integrated cohesive science has not materialized. Here we investigate the status of the field in a data-informed manner, focusing on four indicators, two bibliometric and two socio-institutional. These indicators consistently show that the devised multi-disciplinary program failed to transition to a mature inter-disciplinary coherent field. Bibliometrically, the field has been largely subsumed by (cognitive) psychology, and educationally, it exhibits a striking lack of curricular consensus, raising questions about the future of the cognitive science enterprise.

Is artificial consciousness the solution to AI?

Posted by in categories: computing, driverless cars, Elon Musk, ethics, evolution, futurism, homo sapiens, human trajectories, information science, law enforcement, machine learning, science, Skynet, supercomputing

Artificial Intelligence (AI) is an emerging field of computer programming that is already changing the way we interact online and in real life, but the term ‘intelligence’ has been poorly defined. Rather than focusing on smarts, researchers should be looking at the implications and viability of artificial consciousness as that’s the real driver behind intelligent decisions.

Consciousness rather than intelligence should be the true measure of AI. At the moment, despite all our efforts, there’s none.

Significant advances have been made in the field of AI over the past decade, in particular with machine learning, but artificial intelligence itself remains elusive. Instead, what we have is artificial serfs—computers with the ability to trawl through billions of interactions and arrive at conclusions, exposing trends and providing recommendations, but they’re blind to any real intelligence. What’s needed is artificial awareness.

Elon Musk has called AI the “biggest existential threat” facing humanity and likened it to “summoning a demon,”[1] while Stephen Hawking thought it would be the “worst event” in the history of civilization and could “end with humans being replaced.”[2] Although this sounds alarmist, like something from a science fiction movie, both concerns are founded on a well-established scientific premise found in biology—the principle of competitive exclusion.[3]

21st Century Medicine –Expanding the Boundaries of Preservation Science

Posted by in categories: biotech/medical, cryonics, life extension, science, transportation

21st Century Medicine has developed an entire platform technology focused on the creation and commercialization of hypothermic preservation and cryopreservation techniques that enable protection, preservation, transportation, storage & future use of valuable living systems. These developments have taken science far beyond conventional preservation limits. 21CM scientists continue to prove long-term protection and preservation of complex living systems is not only possible, but commercially viable.

It means that a vital link has been created that we call “Bio Logistics”.

Biopharmaceutical companies get a larger window in which to test new drug candidates on viable premade and cryopreserved tissue slices that function like fresh.

Every now and again, a study is released that makes our heart skip a beat.

Recently, research published in the journal Nature Medicine found that eating cheese can lead to a longer lifespan (and it wasn’t even satire!).

What universities can learn from one of science’s biggest frauds

Posted by in categories: biotech/medical, science

Gunsalus agrees that the Sato case highlights some of the problems with misconduct investigations, and says that if shortcomings emerge, further reviews may be needed. She suggests institutional panels should include external members and that officials should also use a standardized checklist to strengthen their processes. “There should be some way for journals, funders, patients and others to be assured of the credibility and thoroughness of university reviews,” says Gunsalus.


Detailed analysis of misconduct investigations into huge research fraud suggests institutional probes aren’t rigorous enough.
