In recent years, roboticists and computer scientists have introduced various new computational tools that could improve interactions between robots and humans in real-world settings. The overreaching goal of these tools is to make robots more responsive and attuned to the users they are assisting, which could in turn facilitate their widespread adoption.

Researchers at Leonardo Labs and the Italian Institute of Technology (IIT) in Italy recently introduced a new computational framework that allows robots to recognize specific users and follow them around within a given environment. This framework, introduced in a paper published as part of the 2023 IEEE International Conference on Advanced Robotics and Its Social Impacts (ARSO), allows robots re-identify users in their surroundings, while also performing specific actions in response to hand gestures performed by the users.

“We aimed to create a ground-breaking demonstration to attract stakeholders to our laboratories,” Federico Rollo, one of the researchers who carried out the study, told Tech Xplore. “The Person-Following robot is a prevalent application found in many commercial mobile robots, especially in industrial environments or for assisting individuals. Typically, such algorithms use external Bluetooth or Wi-Fi emitters, which can interfere with other sensors and the user is required to carry.”

When water vapor meets metal, the resulting corrosion can lead to mechanical problems that harm a machine’s performance. Through a process called passivation, it also can form a thin inert layer that acts as a barrier against further deterioration.

Either way, the exact chemical reaction is not well understood on an atomic level, but that is changing thanks to a technique called environmental transmission electron microscopy (TEM), which allows researchers to directly view molecules interacting on the tiniest possible scale.

Professor Guangwen Zhou—a faculty member at Binghamton University’s Thomas J. Watson College of Engineering and Applied Science—has been probing the secrets of atomic reactions since joining the Department of Mechanical Engineering in 2007. Along with collaborators from the University of Pittsburgh and the Brookhaven National Laboratory, he has studied the structural and functional properties of metals and the process of making “green” steel.

Fairy circles, a nearly hexagonal pattern of bare-soil circular gaps in grasslands, initially observed in Namibia and later in other parts of the world, have fascinated and baffled scientists for years. Theories for their appearance range from spatial self-organization induced by scale-dependent water-vegetation feedback to pre-existing patterns of termite nests.

Prof. Ehud Meron of Ben-Gurion University of the Negev has been studying the Namibian fairy circles as a case study for understanding how ecosystems respond to water stress. He believes that all theories to date have overlooked the coupling between two robust mechanisms essential for understanding ecosystem response: phenotypic plasticity at the level of a single plant, and spatial self-organization in vegetation patterns at the level of a plant population.

Phenotypic plasticity is the plant’s ability to change its own traits in response to environmental stresses.

Rising levels of respiratory viruses, including flu and COVID-19, are being reported this season. CDC urges the public to get vaccinated, with fewer than two in five adults and children having received the flu vaccine. Visitor restrictions are in place at Riley Hospital due to the surge in illnesses.

Objects in space reveal different aspects of their composition and behavior at different wavelengths of light. Supernova remnant Cassiopeia A (Cas A) is one of the most well-studied objects in the Milky Way across the wavelength spectrum. However, there are still secrets hidden within the star’s tattered remains.

The latest are being unlocked by one of the newest tools in the researchers’ toolbox, the James Webb Space Telescope—and Webb’s recent look in the near-infrared has blown researchers away.

As Vertex and CRISPR Therapeutics’ exa-cel and Verve Therapeutics’ VERVE-101 move forward, questions remain about possible drawbacks of such therapies.

In a new forward-looking Essay, P’aivi T’orm’a highlights the significance and impact of quantum geometry for the future of physics research.

How do we go from 100 to 200 to 1000? PASQAL, a quantum computing startup, is using LASERS. They’ve demonstrated 100 and 200 qubit systems, now they’re talking about making 1000. Here’s the mockup of their system.
