INFECTIOUS DISEASE China replaces its CDC chief “With this new addition of structures illuminating nearly the entire protein universe, we can expect more biological mysteries to be solved each day,” Eric Topol, director of the Scripps Research Translational Institute, tweeted about the achievement.
The latest structures were released into an existing database through a partnership with the European Molecular Biology Laboratory’s European Bioinformatics Institute. DeepMind released some 350,000 predicted structures last year and AlphaFold has since continued to churn out new structures, taking about 10 to 20 seconds per protein, accordin to the company.

The structural bounty comes from AlphaFold, one of the new AI programs that have cracked the protein-folding problem and learned how to accurately derive 3D shapes of proteins from their amino acid sequences. In a potentially transformative event for drug development and biology studies, the artificial intelligence (AI) company DeepMind last week unveiled the likely structures of nearly all known proteins, more than 200 million in total, from organisms ranging from bacteria to humans.
In the other study, of almost 450 Asian, Black, Latino, white, and multiracial people ages 90 or older, those who experienced discrimination throughout their lives had lower semantic memory-general world knowledge accumulated over time-compared with those who experienced little to no discrimination.ĪlphaFold predicted the structure of a protein from the thale cress plant that may confer disease resistance. Black individuals, who are more likely to have Alzheimer’s and other dementias, were the most affected. In an analysis of nearly 1000 middle-aged Black, Latino, and white adults in the United States, researchers found past experiences of individual and structural racism, such as residential segregation, were correlated with poorer episodic memory-the ability to recall personal events in one’s life. Systemic inequities such as limited health care access are likely responsible. The work supports the findings of previous research and systemic inequities such as limited health care access are likely responsible. Two studies presented this week at the Alzheimer’s Association International Conference in San Diego find people who experienced racism and discrimination have lower memory scores, a symptom of dementia.
