A scientific advance in studying early-stage lung cancer

Lung cancer is the leading cancer killer in the US. It is often missed in its earlier stages, and while recent imaging advances have enabled earlier detection, there are still no targeted treatments for early-stage lung cancers. New research from Boston Children's Hospital, in collaboration with Boston University and UCLA, provides an accelerated platform for identifying and testing potential treatments: 'organoids' created from lung cells.

If relaxed too soon, physical distancing measures might have been all for naught

If physical distancing measures in the United States are relaxed while there is still no COVID-19 vaccine or treatment and while personal protective equipment remains in short supply, the number of resulting infections could be about the same as if distancing had never been implemented to begin with, reports a UCLA-led team of mathematicians and scientists.

Coronavirus antibodies fall dramatically in first 3 months after mild cases of COVID-19

A study by UCLA researchers shows that in people with mild cases of COVID-19, antibodies against SARS-CoV-2 -- the virus that causes the disease -- drop sharply over the first three months after infection, decreasing by roughly half every 73 days. If sustained at that rate, the antibodies would disappear within about a year.

Deep learning enables early detection and classification of live bacteria using holography

Rapid identification of the presence of pathogenic bacteria in food, water, or bodily fluid samples is very important and yet extremely challenging. Scientists at UCLA invented a high-throughput holographic system, which continuously monitors a test plate, where bacteria grow, with deep learning models for early and automated detection of bacterial colonies, achieving a limit-of-detection of 1 colony forming bacterium per 1 Liter of water sample in less than 9 hours of total test time.

New ‘Computer Prophet’ generates profound metaphors for life and death

Life is a prison in which we all live. Once the bars are down, it becomes obscene what everybody else is doing. So says the Computer Prophet, a new AI system that spits out pearls of wisdom in the form of metaphors. The project is the brainchild of UCLA student Elias Henriksen, who created it to help us answer life’s most profound questions. We often express our existential concerns through metaphors, as they help us relate our own experiences to abstract concepts. Research suggests that people ...

How conspiracy theories emerge -- and how their storylines fall apart

A new study in the journal PLOS One, by UCLA professors of engineering and folklore, uses machine learning to visualize how unrelated facts and false information can connect into a narrative framework that would quickly fall apart if some of elements are taken out of the mix. One of the characteristics of a conspiracy theory narrative framework-- like what built up around Pizzagate online -- is that it is easily disconnected, they found.
