A promising three-terminal diode for wireless communication and optically driven computing

Posted by in category: computing

Two-terminal devices are electronic components connected to electrical circuits via two electrical terminals. Although these components are the key building blocks of most existing devices, they can limit a system’s performance and functions.

Researchers find LLMs are easy to manipulate into giving harmful information

Posted by in category: robotics/AI

A team of AI researchers at AWS AI Labs, Amazon, has found that most, if not all, publicly available Large Language Models (LLMs) can be easily tricked into revealing dangerous or unethical information.

Researchers realize multiphoton electron emission with non-classical light

Posted by in categories: particle physics, quantum physics

Strong field quantum optics is a rapidly emerging research topic, which merges elements of non-linear photoemission rooted in strong field physics with the well-established realm of quantum optics. While the distribution of light particles (i.e., photons) has been widely documented both in classical and non-classical light sources, the impact of such distributions on photoemission processes remains poorly understood.

The Making of Mankind: Evolutionary Insights into the Origin and Rise of Homo Sapiens

Posted by in category: evolution

Humans are arguably the most peculiar species that has ever existed.


Acknowledging the unique aspects of human evolution underscores our extraordinary place in the grander scheme—a species with one foot in the natural world and the other in a realm of conscious self-awareness and purpose. This dual heritage suggests„.

Physicists propose path to faster, more flexible robots

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

In a May 15 paper released in the journal Physical Review Letters, Virginia Tech physicists revealed a microscopic phenomenon that could greatly improve the performance of soft devices, such as agile flexible robots or microscopic capsules for drug delivery.

The paper, written by doctoral candidate Chinmay Katke, assistant professor C. Nadir Kaplan, and co-author Peter A. Korevaar from Radboud University in the Netherlands, proposes a new physical mechanism that could speed up the expansion and contraction of hydrogels. For one thing, this opens up the possibility for hydrogels to replace rubber-based materials used to make flexible robots—enabling these fabricated materials to perhaps move with a speed and dexterity close to that of .

Soft robots are already being used in manufacturing, where a hand-like device is programmed to grab an item from a conveyer belt—picture a hot dog or piece of soap—and place it in a container to be packaged. But the ones in use now lean on hydraulics or pneumatics to change the shape of the “hand” to pick up the item.
