Seven federal workers who abruptly lost their jobs in recent weeks say they are worried that thousands of biological samples—from human urine to frozen rodent organs—may be left to rot in a government laboratory in West Virginia. The workers left behind the samples, which they say include lungs, spleens, and brains collected from rats and mice, after the Trump administration laid off or placed on administrative leave about two-thirds of the staff working at facilities managed by the National Ins

There, a research chemist named Ed Sisco and his team had developed methods for detecting trace amounts of drugs, explosives, and other dangerous materials—techniques that could protect law enforcement officials and others who had to collect these samples. Essentially, Sisco’s lab had fine-tuned a technology called DART (for “direct analysis in real time”) mass spectrometry—which the US Transportation Security Administration uses to test for explosives by swiping your hand—to enable the detectio

The most common way to detect bird flu involves swabbing potentially contaminated sites and sequencing the DNA that’s been collected, a process that can take up to 48 hours. The new device samples the air in real time, running the samples past a specialized biosensor every five minutes. The sensor has strands of genetic material called aptamers that were used to bind specifically to the virus. When that happens, it creates a detectable electrical change. The research, published in ACS Sensors i

Smart turn detection This is an open source, community-driven, native audio turn detection model. HuggingFace page: pipecat-ai/smart-turn Turn detection is one of the most important functions of a conversational voice AI technology stack. Turn detection means deciding when a voice agent should respond to human speech. Most voice agents today use voice activity detection (VAD) as the basis for turn detection. VAD segments audio into "speech" and "non-speech" segments. VAD can't take into acco

Astronauts on the International Space Station often suffer from various immune system dysfunctions, including allergies and skin rashes, even though they go through rigorous screening and are probably among the healthiest people on (or at least near) Earth. “It’s hard to pinpoint the exact causes for a lot of these symptoms, but we believe microbiome disruptions that happen in their bodies and in their environment up there could be playing an important part”, says Rodolfo Salido Benitez, a bioen
