Dataset bridges human vision and machine learning

Neuroscientists and computer vision scientists say a new dataset of unprecedented size—comprising brain scans of four volunteers who each viewed 5,000 images—will help researchers better understand how the brain processes images. Researchers at Carnegie Mellon University and Fordham University, reporting today in the journal Scientific Data, said acquiring functional magnetic resonance imaging (fMRI) scans at […]

Artificial intelligence singles out neurons faster than a human can

Biomedical engineers at Duke University have developed an automated process that can trace the shapes of active neurons as accurately as human researchers can, but in a fraction of the time. This new technique, based on using artificial intelligence to interpret video images, addresses a critical roadblock in neuron analysis, allowing researchers to rapidly gather […]

Depression ages the brain, first human trials suggest

Depression ages the brain, first human trials suggest: Damage appears 10 years early in people with the mental health condition – but it could be treated with ketamine Synapses (the connections between neurons) start thinning earlier in people with depression, study finds The small study of 10 people is the first to test the theory […]

Influenza A deliberately enhances levels of the human p53 protein to reduce anti-viral gene and protein expression

Genome editing technology is helping A*STAR scientists unravel how the Influenza A virus (IAV) exploits human anti-viral responses. IAV remains a key challenge for global health resources, not least because of wide variations in symptom severity experienced by different people, even when they are infected by the same strain. This implies that there are host […]

New model mimics human tumors for accurate testing of cancer drugs

Walter and Eliza Hall Institute researchers have genetically engineered a new laboratory model that enables accurate testing of anti-cancer drugs by mimicking the complexity of human cancers. Using this advanced model, researchers will be able to discover the safest and most effective ways to use promising drugs called MCL-1 inhibitors in the clinic. The work […]
