My name is Artem, I’m a computational neuroscience student and researcher. In this video we discuss engrams – fundamental units of memory in the brain. We explore what engrams are, how memory is allocated, where it is stored, and how different memories become linked with each other.

My name is Artem, I’m a computational neuroscience student and researcher. In this video we discuss the Tolman-Eichenbaum Machine – a computational model of a hippocampal formation, which unifies memory and spatial navigation under a common framework.

Wouldn’t it be nice to have a computer answer all of the biggest questions in the universe?

In his first year of graduate school, in 2013, Michael Wagman walked into his advisor’s office and asked, “Can you help me simulate the universe?”

Wagman, a theoretical physicist and associate scientist at the US Department of Energy’s Fermi National Accelerator Laboratory, thought it seemed like a reasonable question to ask. “We have all of these beautiful theoretical descriptions of how we think the world works, so I wanted to try and connect those formal laws of physics to my everyday experience of reality,” he says.

As connectivity continues to expand and the number of devices on a network with it, IoT’s ambition of creating a world of connected things grows. Yet, with pros, comes the cons, and the flip side of this is the growing security challenges that come with it too.

Security has been a perennial concern for IoT since it’s utilisation beyond its use for basic functions like tallying the stock levels of a soda machine. However, for something of such interest to the industry, plans for standardisation remain allusive. Instead, piece meal plans to ensure different elements of security, like zero trust for identity and access management for devices on a network, or network segmentation for containing breaches, are undertaken by different companies according to their needs.

Yet with the advancement of technology, things like quantum computing pose a risk to classic cryptography methods which, among other things, ensures data privacy is secure when being transferred from device to device or even to the Cloud.

Transistors are crucial electronic components that regulate, amplify and control the flow of current inside most existing devices. In recent years, electronics engineers have been trying to identify materials and design strategies that could help to further improve the performance of transistors, while also reducing their size.

Two-dimensional (2D) transition metal dichalcogenides have some advantageous properties that could help to enhance the capabilities of transistors. While past studies have demonstrated the potential of these materials in individual transistors, their use for developing entire integrated circuits (ICs) that operate at high frequencies has proved challenging.

Researchers at Nanjing University in China recently created new ICs that can operate at GHz frequencies, based on the 2D semiconducting material monolayer molybdenum disulfide (MoS2). Their devices, presented in a Nature Electronics paper, rely on MoS2-based field-effect transistors (FETs).

Quantum advantage is the milestone the field of quantum computing is fervently working toward, where a quantum computer can solve problems that are beyond the reach of the most powerful non-quantum, or classical, computers.

Quantum refers to the scale of atoms and molecules where the laws of physics as we experience them break down and a different, counterintuitive set of laws apply. Quantum computers take advantage of these strange behaviors to solve problems.

In 1960, DARPA funded three university-based Inderdisciplinary Laboratories (IDLs) that opened the way toward an enormous field of research and development known today as materials science and engineering. In this video, DARPA program managers, DARPA-funded researchers, and a Naval Research Laboratory scientist tell this field-building story as it unfolded over the past six decades, all the while delivering breakthroughs in the way materials are designed, processed, and deployed to push technologies forward. Intelligent processing of materials (IPM), accelerated insertion of materials (AIM), and integrated computational materials engineering (ICME) are among the specific programs detailed in the video. DARPA is currently developing technologies that enable the crafting of new materials with unprecedented properties by designing and controlling matter from atoms on up to human-scale systems.

The COVID-19 pandemic supply shortfalls and geopolitical issues cast a bright light on the decline of semiconductor manufacturing in the United States, down from 37 percent of the global total in 1993 to about 12 percent now. The Creating Helpful Incentives to Produce Semiconductors and Science Act of 2022 (CHIPS Act) directed $280 billion in spending, with the bulk on scientific research and development.

America needs better computer chips.

Mobile devices are ubiquitous; we carry them around in a pocket or purse and use them for everyday tasks. However, they are connected to centralized servers and thus cannot learn much about or adjust to their complicated and changing environments independently.
