Artificial Intelligence Aids Gene Activation Discovery

With the aid of artificial intelligence, UC San Diego scientists have solved a long-standing puzzle in human gene activation. The discovery described in the journal Nature could be used to control gene activation in biotechnology and biomedical applications.

Machine learning enables long-awaited code breakthrough with potential applications in biomedicine. Scientists have long known that human genes spring into action through instructions delivered by the precise order of our DNA, directed by the four different types of individual links, or “bases,” coded A, C, G and T.

Nearly 25% of our genes are widely known to be transcribed by sequences that resemble TATAAA, which is called the “TATA box...

New tool might aid the adoption of technologies such as autonomous vehicles. One of the biggest impediments to adoption of new technologies is trust in AI.

Now, a new tool developed by USC Viterbi Engineering researchers generates automatic indicators if data and predictions generated by AI algorithms are trustworthy. Their research paper, “There Is Hope After All: Quantifying Opinion and Trustworthiness in Neural Networks” by Mingxi Cheng, Shahin Nazarian and Paul Bogdan of the USC Cyber Physical Systems Group, was featured in Frontiers in Artificial Intelligence.

Neural networks are a type of artificial intelligence that are modeled after the brain and generate predictions...

Artificial Intelligence yields new Antibiotic

MIT researchers used a machine-learning algorithm to identify a drug called halicin that kills many strains of bacteria. Halicin (top row) prevented the development of antibiotic resistance in E. coli, while ciprofloxacin (bottom row) did not.

A deep-learning model identifies a powerful new drug that can kill many species of antibiotic-resistant bacteria

Using a machine-learning algorithm, MIT researchers have identified a powerful new antibiotic compound. In laboratory tests, the drug killed many of the world’s most problematic disease-causing bacteria, including some strains that are resistant to all known antibiotics. It also cleared infections in two different mouse models.

The computer model, which can screen more than a hundr...
