Scientists discover new code governing gene activity      (via sciencedaily.com)     Original source 

A newly discovered code within DNA -- coined 'spatial grammar' -- holds a key to understanding how gene activity is encoded in the human genome. This breakthrough finding revealed a long-postulated hidden spatial grammar embedded in DNA. The research could reshape scientists' understanding of gene regulation and how genetic variations may influence gene expression in development or disease.

Peering into the mind of artificial intelligence to make better antibiotics      (via sciencedaily.com)     Original source 

Artificial intelligence (AI) has exploded in popularity as of late. But just like a human, it's hard to read an AI model's mind. Explainable AI (XAI) could help us do just that by providing justification for a model's decisions. And now, researchers are using XAI to scrutinize predictive AI models more closely, which could help make better antibiotics.

New insights on how bird flu crosses the species barrier      (via sciencedaily.com)     Original source 

The avian influenza virus needs to mutate to cross the species barrier and to infect and replicate within mammalian cells. Scientists have now deciphered the structure of the avian influenza virus's polymerase when it interacts with a human protein essential for the virus to replicate within the cell. The structure of this replication complex provides important information about the mutations that avian influenza polymerase must undergo to adapt to mammals, including humans. These results can help scientists monitor the evolution and adaptability of bird flu strains, such as H5N1 or H7N9, towards infecting other species.

Zebrafish use surprising strategy to regrow spinal cord      (via sciencedaily.com)     Original source 

A new study maps out a detailed atlas of all the cells involved in regenerating the zebrafish spinal cord. In an unexpected finding, the researchers showed that survival and adaptability of the severed neurons themselves is required for full spinal cord regeneration. Surprisingly, the study showed that stem cells capable of forming new neurons play a complementary role but don t lead the process.

Robot planning tool accounts for human carelessness      (via sciencedaily.com)     Original source 

A new algorithm may make robots safer by making them more aware of human inattentiveness. In computerized simulations of packaging and assembly lines where humans and robots work together, the algorithm developed to account for human carelessness improved safety by about a maximum of 80% and efficiency by about a maximum of 38% compared to existing methods.
