New transistors integrating high-k perovskite oxides and 2D semiconductors

Posted by in categories: computing, quantum physics

Over the past decades, electronics engineers and material scientists worldwide have been investigating the potential of various materials for fabricating transistors, devices that amplify or switch electrical signals in electronic devices. Two-dimensional (2D) semiconductors have been known to be particularly promising materials for fabricating the new electronic devices.

Despite their advantages, the use of these materials in electronics greatly depends on their integration with high-quality dielectrics, insulating materials or materials that are poor conductors of electrical current. These materials, however, can be difficult to deposit on 2D substrates.

Researchers at Nanyang Technological University, Peking University, Tsinghua University, and the Beijing Academy of Quantum Information Sciences have recently demonstrated the successful integration of single-crystal strontium titrate, a high-κ perovskite , with 2D semiconductors, using van der Waals forces. Their paper, published in Nature Electronics, could open new possibilities for the development of new types of transistors and electronic components.

Transfusion of brain fluid from young mice is a memory-elevating elixir for old animals

Posted by in categories: biotech/medical, robotics/AI

For a human, one of the first signs someone is getting old is the inability to remember little things; maybe they misplace their keys, or get lost on an oft-taken route. For a laboratory mouse, it’s forgetting that when bright lights and a high-pitched buzz flood your cage, an electric zap to the foot quickly follows.

But researchers at Stanford University discovered that if you transfuse cerebrospinal fluid from a young mouse into an old one, it will recover its former powers of recall and freeze in anticipation. They also identified a protein in that cerebrospinal fluid, or CSF, that penetrates into the hippocampus, where it drives improvements in memory.

The tantalizing breakthrough, published Wednesday in Nature, suggests that youthful factors circulating in the CSF, or drugs that target the same pathways, might be tapped to slow the cognitive declines of old age. Perhaps even more importantly, it shows for the first time the potential of CSF as a vehicle to get therapeutics for neurological diseases into the hard-to-reach fissures of the human brain.

Newly-developed lensless camera uses neural network and transformer to produce sharper images faster

Posted by in category: robotics/AI

Lensless cameras have many potential use-cases but have generally been held back by lengthy processing requirements and low-resolution images. A research from a team at the Tokyo Institute of Technology is looking to change that.

Costa Rica declares state of emergency over ransomware attack

Posted by in categories: climatology, computing, finance, government

Costa Rica has declared a state of emergency after ransomware hackers crippled computer networks across multiple government agencies, including the Finance Ministry.

The official declaration, published on a government website Wednesday, said that the attack was “unprecedented in the country” and that it interrupted the country’s tax collection and exposed citizens’ personal information.

The hackers initially broke into the Finance Ministry on April 12, it said. They were able to spread to other agencies, including the Ministry of Science, Technology and Telecommunications and the National Meteorological Institute.

New tech can double spectral bandwidth in some 5G systems

Posted by in categories: computing, internet, quantum physics

Some materials, like wood, are insulators that block the flow of electricity. Conductors, such as copper, allow for electricity to flow through them. Other materials—semiconductors—can be either/or depending on conditions such as applied electric field or temperature. Unlike wood or copper or silicon, though, topological insulators (TIs) are an exotic state of matter that is conductive on the surface, but not in the bulk. Such unique material properties have great scientific implications and could be of use in a range of technologies, including wireless communications, radar and quantum information processing.

Through a , the research labs of Aravind Nagulu, assistant professor in the Preston M. Green Department of Electrical & Systems Engineering at Washington University in St. Louis, and colleagues from Columbia University and the City University of New York’s Advanced Science Research Center have demonstrated the first implementation of an electromagnetic topological insulator on an integrated chip.

The collaborative project’s findings were published May 2 in the journal Nature Electronics.

Will your existing data infrastructure support ESG reporting?

Posted by in categories: business, climatology, finance

I’ve noticed a tremendous change in how companies invest in their ESG initiatives. No longer is it just their peers or employees holding them accountable; it’s also national and international governing bodies. In 2020, the U.S. Securities and Exchange Commission created an ESG disclosure framework for consistent and comparable reporting metrics, and just recently the organization amended that framework to deepen the level of reporting required from organizations. And in March of this year, the U.K. Task Force on Climate-Related Financial Disclosures mandated U.K.-registered companies and financial institutions to disclose climate-related financial information.

It’s this very shift that has convinced organizational leaders that just having ESG initiatives isn’t enough anymore. It’s the ability to accurately and consistently report ESG metrics that may ultimately make the difference for a company to thrive in the next era of sound business practices.

When you look at this new challenge for ESG reporting, there’s simply no denying it: The single most important factor in successfully adhering to ESG standards is data.
