In response to these challenges, researchers have engineered spin-triplet superconducting valves capable of switching superconducting currents on and off as per the need.

Key Points: 
  • In response to these challenges, researchers have engineered spin-triplet superconducting valves capable of switching superconducting currents on and off as per the need.
  • To make the fabrication of spin-triplet superconducting valves easier, a team of researchers led by Assistant Professor Kun-Rok Jeon from the Department of Physics at Chung-Ang University, Korea, has now developed an antiferromagnetic analogue of the spin-triplet supercurrent spin valves.
  • The functionality of the SQUID demonstrates the potential of antiferromagnetic spin valves in the realm of superconducting spintronics.
  • Title of original paper: Chiral antiferromagnetic Josephson junctions as spin-triplet supercurrent spin valves and d.c. SQUIDs

Navigating the risks and benefits of AI: Lessons from nanotechnology on ensuring emerging technologies are safe as well as successful

The specific details of these technologies are, of course, a world apart.

Key Points: 
  • The specific details of these technologies are, of course, a world apart.
  • As scholars of the future of innovation, we explore these parallels in a new commentary in the journal Nature Nanotechnology.

Nanotech excitement and fear

    • In the late 1990s and early 2000s, nanotechnology transitioned from a radical and somewhat fringe idea to mainstream acceptance.
    • The era saw public protests against nanotechnology and – disturbingly – even a bombing campaign by environmental extremists that targeted nanotechnology researchers.
    • These included potential health and environmental impacts, social and ethical issues, regulation and governance, and a growing need for public and stakeholder collaboration.
    • The result was a profoundly complex landscape around nanotechnology development that promised incredible advances yet was rife with uncertainty and the risk of losing public trust if things went wrong.

How nanotech got it right

    • At the time, working on responsible nanotechnology development felt like playing whack-a-mole with the health, environment, social and governance challenges presented by the technology.
    • This included multistakeholder partnerships, consensus standards, and initiatives spearheaded by global bodies such as the Organization for Economic Cooperation and Development.
    • As a result, many of the technologies people rely on today are underpinned by advances in nanoscale science and engineering.
    • In the early 2000s, the initiative brought together representatives from across the government to better understand the risks and benefits of nanotechnology.

Experts only at the table

    • Yet despite similar aspirations around AI, these same levels of diversity and engagement are missing.
    • The White House has prioritized consultations with AI company CEOs, and Senate hearings have drawn preferentially on technical experts.
    • More importantly, they bring a diversity of expertise and perspectives to the table that is essential for the successful development of an advanced technology like AI.

The clock is ticking

    • But this will happen only if society applies the lessons from past advanced technology transitions like the one driven by nanotechnology.
    • The early days of an advanced technology transition set the trajectory for how it plays out over the coming decades.

NEW YORK, July 27, 2023 /PRNewswire-PRWeb/ -- Investigators at the Icahn School of Medicine at Mount Sinai have designed an innovative RNA-based strategy to activate dendritic cells—which play a key role in immune response—that eradicated tumors and prevented their recurrence in mouse models of melanoma.

Key Points: 
  • Cancer cells employ strategies to switch off various stages of the cancer-immunity cycle, the process by which dendritic cells educate T cells to kill cancer cells.
  • Their investigations revealed encouraging results, as the regimen reduced tumors in mouse models of B cell lymphoma by 83 percent.
  • They also tested it in mouse models of breast cancer, where approximately half of the mice favorably responded.
  • The study was funded in part by National Cancer Institute grant P30 CA016058 and National Institute of General Medical Sciences grant R35GM144117.

OLOMOUC, Czech Republic, April 12, 2022 /PRNewswire/ --The sun instead of electric furnaces and a cheap nanomaterial instead of gold.

Key Points: 
  • OLOMOUC, Czech Republic, April 12, 2022 /PRNewswire/ --The sun instead of electric furnaces and a cheap nanomaterial instead of gold.
  • The composition of the nanomaterial resembles common, naturally occurring minerals, yet it can replace noble metals used so far.
  • According to data from MarketWatch, the market for aniline compounds is approximately $12 billion per year, with a significant increase on the way.
  • This was the right step, and we are already negotiating industrial applications of the technology with potential investors, especially in Germany," concluded Zboil.
