Smell significantly enhances sense of realism in virtual reality, researchers find

Posted by in category: virtual reality

You walk along a dark winding path deep in a forest. There is a swamp you must wade through. You spot an old wooden shack and walk to it past a smoldering fire. Its broken shutters and verandah sag under vines and neglect.

Google Builds Language Models with Socratic Dialogue to Improve Zero-Shot Multimodal Reasoning Capabilities

Posted by in category: habitats

Large-scale language-based foundation models such as BERT, GPT-3 and CLIP have exhibited impressive capabilities ranging from zero-shot image classification to high-level planning. In most cases, these large language models, visual-language models and audio-language models remain domain-specific and rely highly on the distribution of their training data. The models thus obtain different although complementary common-sense knowledge within specific domains. But what if such models could effectively communicate with one another?

In the new paper Socratic Models: Composing Zero-Shot Multimodal Reasoning with Language, Google researchers argue that the diversity of different foundation models is symbiotic and that it is possible to build a framework that uses structured Socratic dialogue between pre-existing foundation models to formulate new multimodal tasks as a guided exchange between the models without additional finetuning.

This work aims at building general language-based foundation models that embrace the diversity of pre-existing language-based foundation models by levering structured Socratic dialogue, and offers insights into the applicability of the proposed Socratic Models on challenging perceptual tasks.

Exploring how fungal infections spread in the human lung

Posted by in categories: biotech/medical, computing, information science

A chip-based infection model developed by researchers in Jena, Germany, enables live microscopic observation of damage to lung tissue caused by the invasive fungal infection aspergillosis. The team developed algorithms to track the spread of fungal hyphae as well as the response of immune cells. The development is based on a “lung-on-chip” model also developed in Jena and can help reduce the number of animal experiments. The results were presented in the journal Biomaterials.

Aspergillosis is a mold infection caused by Aspergillus fumigatus, which often affects the lungs. The disease can be fatal, especially in immunocompromised individuals. In these cases, invasive aspergillosis usually occurs with fungal hyphae invading . So far, there are only a few active substances that can combat such fungal infections. “That’s why it was so important for us to be able to represent this invasive growth in a ,” says Marie von Lilienfeld-Toal, who co-led the study. The internist is a professor at the Department of Internal Medicine II at Jena University Hospital and conducts research at the Leibniz Institute for Natural Product Research and Infection Biology—Hans Knöll Institute (Leibniz-HKI) in Jena, Germany.

The new aspergillosis infection model should help to better observe both the growth of the fungus and the reaction of the immune system and to find possible new approaches for therapies. In addition, new active substances can be tested. The expertise for this is available in Jena: Organ chips have long been developed at the university hospital. The startup Dynamic42, which manufactures the lung chips used in the study, was founded there. First author Mai Hoang also joined the company after completing her doctorate.

Why Time Travel Is Already Possible, According To NASA

Posted by in categories: space, time travel

We can travel in time, just not like in the movies Earendel was observed using an effect where the fabric of space-time is warped by gravity – a phenomenon predicted by Einstein. This causes light to bend as it passes by objects with large masses, like planets, suns, or even galaxies, allowing us to see around and even behind these objects.

Microfossils may be evidence life began ‘very quickly’ after Earth formed

Posted by in category: biological

Scientists believe they have found evidence of microbes that were thriving near hydrothermal vents on Earth’s surface just 300m years after the planet formed – the strongest evidence yet that life began far earlier than is widely assumed.

If confirmed, it would suggest the conditions necessary for the emergence of life are relatively basic.

NASA Perseverance Mars Rover Snaps Wreckage of Its Own Parachute and Landing System

Posted by in category: space

NASA’s Perseverance rover is hightailing it to a fascinating river delta region in the Jezero Crater on Mars. But to get there, it first had to pass near its original landing site. Images from there are a trip down memory lane, back to when Percy dramatically landed on the red planet in February 2021.

Steve Ruff, Arizona State University associate research professor and Mars geologist, runs the Mars Guy channel on YouTube. He posted a video on Sunday recapping the rover’s arrival on mars and what happened to the parachute and back shell — two key components of the landing system that delivered Percy safely to the surface.

Rotating blue laser light reveals unimagined dynamics in living cells

Posted by in categories: biotech/medical, nanotechnology

When cities transform into a colorful world of lights as darkness falls, it’s often only possible to estimate their contours, which depending on the perspective can draw the attention to key details or trivia. In fluorescence microscopy, biological cells are marked with fluorescent dyes and excited to luminesce in specific areas by optical switches– like a city at night. However, this light is usually too faint for small, rapid objects, or even goes out after a while. This is known as fluorescence bleaching.

Now, a new approach developed by Prof. Dr. Alexander Rohrbach and his team in the Laboratory for Bio-and Nano-Photonics at the University of Freiburg has found a way to make the smallest objects clearly visible without fluorescence. In this way, cellular structures or virus-sized particles can be observed 100 to 1,000 times longer, ten to 100-times faster and with almost doubled resolution than with . While fluorescence microscopy records what you might call “night-time images” of structures, ROCS microscopy takes “day-time images”—opposites that can complement each other excellently. Rohrbach and his colleagues describe various applications of the technology in the latest issue of Nature Communications.
