Technology protects researchers from dangerous samples
03-Feb-2023
Smart voice assistants are a popular way for people to get quick answers or play their favorite music. That same technology could make the laboratory safer for scientists and technicians who handle potentially infectious samples. Researchers in ACS Sensors now report a small, voice-activated ...
18-Jan-2023
In a first for the genetic toolset known as CRISPR, a recently discovered protein has been found to act as a kind of multipurpose self-destruct system for bacteria, capable of degrading single-stranded RNA, single-stranded DNA and double-stranded DNA. With its abilities to target so many types of ...
A test for a single immune system molecule on nasal swabs can help detect stealthy viruses not identified in standard tests
12-Jan-2023
As the COVID-19 pandemic showed, potentially dangerous new viruses can begin to spread in the population well before the global public health surveillance system can detect them. However, Yale researchers have found that testing for the presence of a single immune system molecule on nasal swabs ...
AI-powered analysis accurately reflects risk of cognitive decline and Alzheimer’s disease based on brain age
11-Jan-2023
The human brain holds many clues about a person’s long-term health — in fact, research shows that a person’s brain age is a more useful and accurate predictor of health risks and future disease than their birthdate. Now, a new artificial intelligence (AI) model that analyzes magnetic resonance ...
Scientists are testing Raman spectroscopy as a diagnostic tool for Lyme disease
10-Jan-2023
Research by two Texas A&M University scientists is focused on improving Lyme disease treatment outcomes by developing a test that’s both more accurate and more efficient than the current test for the infection. Lyme disease, the fastest growing vector-borne illness in the U.S., according to the ...
Drexel researchers use the chatbot to spot Alzheimer's indicators in spontaneous speech
03-Jan-2023
The artificial intelligence algorithms behind the chatbot program ChatGPT — which has drawn attention for its ability to generate humanlike written responses to some of the most creative queries — might one day be able to help doctors detect Alzheimer’s Disease in its early stages. Research from ...
20-Dec-2022
Cryo-electron microscopy by University of Alabama at Birmingham researchers has exposed the structure of a bacterial virus with unprecedented detail. This is the first structure of a virus able to infect Staphylococcus epidermidis, and high-resolution knowledge of structure is a key link between ...
Molecular orientation is key to designing better materials
12-Dec-2022
In some materials, the molecules line up in a regular, repeating pattern. In others, they all point in random directions. But in many advanced materials used in medicine, computer chip manufacturing and other industries, the molecules arrange themselves in complex patterns that dictate the ...
A new algorithm could spot early signs of respiratory diseases in hospitals and at home
09-Dec-2022
Pneumonia is one of the world's leading causes of death and affects over a million people a year in the United States. The disease disproportionately impacts children, older adults, and hospitalized patients. To give them the greatest chance at recovery, it is crucial to catch and treat it early. ...
Microphone sensor and machine learning can classify excretion events, identify cholera or other bowel diseases, all without identifiable information
07-Dec-2022
Cholera, a bacterial disease that induces diarrhea, affects millions of people and results in about 150,000 deaths each year. Identifying potential communal disease spread for such an outbreak would alert health professionals early and improve the allocation of resources and aid. However, for ...
