Microplastics are an environmental hazard found nearly everywhere on Earth, released by the breakdown of tires, clothing, and plastic packaging. Another significant source of microplastics is tiny beads that are added to some cleansers, cosmetics, and other beauty products.

In an effort to cut off some of these microplastics at their source, MIT researchers have developed a class of biodegradable materials that could replace the plastic beads now used in beauty products. These polymers break down into harmless sugars and amino acids.

MIT researchers developed biodegradable materials that could replace the plastic microbeads now used in beauty products. The materials could also be used to encapsulate nutrients for food fortification.

Chatbots can wear a lot of proverbial hats: dictionary, therapist, poet, all-knowing friend. The artificial intelligence models that power these systems appear exceptionally skilled and efficient at providing answers, clarifying concepts, and distilling information. But to establish trustworthiness of content generated by such models, how can we really know if a particular statement is factual, a hallucination, or just a plain misunderstanding?

In many cases, AI systems gather external information to use as context when answering a particular query. For example, to answer a question about a medical condition, the system might reference recent research papers on the topic. Even with this relevant context, models can make mistakes with what feels like high doses of confidence. When a model errs, how can we track that specific piece of information from the context it relied on — or lack thereof?

To help tackle this obstacle, MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) researchers created ContextCite, a tool that can identify the parts of external context used to generate any particular statement, improving trust by helping users easily verify the statement.

Creating realistic 3D models for applications like virtual reality, filmmaking, and engineering design can be a cumbersome process requiring lots of manual trial and error.

While generative artificial intelligence models for images can streamline artistic processes by enabling creators to produce lifelike 2D images from text prompts, these models are not designed to generate 3D shapes. To bridge the gap, a recently developed technique called Score Distillation leverages 2D image generation models to create 3D shapes, but its output often ends up blurry or cartoonish.

The oral mucosa is a critical barrier tissue that is continually exposed to pathogens, but antiviral immune responses in this tissue are poorly understood. Moreover, recent viral outbreaks, including SARS-CoV-2 and mpox, feature oral symptoms. This Review discusses antiviral immunity in the oral cavity and presents current mouse models for the study of oral viral infections.

Even spider love lives show an effect of climate uncertainty: Stressed males may offer a bit of silk-wrapped junk rather than a tasty insect treat.

NIH scientists used multiphoton imaging of live human arteries and other research tools to gain a new and unexpected understanding of how hemoglobin helps regulate blood vessel dilation. The research may lead to new ways to treat malaria and other vascular diseases. Learn more about these studies.

A look inside human arteries reveals a new picture of hemoglobin’s role there and may lead to treatments for malaria and other vascular diseases.

This innovative sterilizer is ideal for remote areas, promoting sanitation and eco-friendly farming.

Seoul, South Korea, December 9: A South Korean company, Palsoo, has unveiled a portable sterilization system that utilizes regular tap water to eliminate 99.8% of airborne bacteria and viruses effectively.

This technology, which combines plasma activation with solar charging, offers a sustainable solution for sanitation in areas lacking electricity or facing harsh conditions.
