Researchers outline promises, challenges of understanding AI for biological discovery      (via sciencedaily.com)     Original source 

Machine learning is a powerful tool in computational biology, enabling the analysis of a wide range of biomedical data such as genomic sequences and biological imaging. But when researchers use machine learning in computational biology, understanding model behavior remains crucial for uncovering the underlying biological mechanisms in health and disease. Researchers now propose guidelines that outline pitfalls and opportunities for using interpretable machine learning methods to tackle computational biology problems.

Children can inherit early aging symptoms from parents who abuse alcohol, researchers find      (via sciencedaily.com)     Original source 

Researchers say they now know that offspring are inheriting dysfunction in their mitochondria as a result of their parents' substance abuse. This dysfunction causes these individuals to show early signs of age-related disease when they're still considered young, usually in their 40s.

Unlocking the secrets of salt stress tolerance in wild tomatoes      (via sciencedaily.com)     Original source 

As our climate changes and soil salinity increases in many agricultural areas, finding crops that can thrive in these challenging conditions is crucial. Cultivated tomatoes, while delicious, often struggle in salty soils. Their wild cousins, however, have evolved to survive in diverse and often harsh environments. A recent study delved into the genetic treasure trove of wild tomatoes to uncover secrets of salt tolerance that could be used to develop resilient crop varieties.

Mix of factors prompts owl monkeys to leave their parents      (via sciencedaily.com)     Original source 

There comes a point in the lives of young owl monkeys when they leave their parents and strike out on their own to find a mate. In a new study of a wild population of Azara's owl monkeys in northern Argentina, researchers reveal that a combination of social and ecological factors influences when these tree-dwelling monkeys peel away from their parents and siblings. According to their findings -- which were based on 25 years of genetic and demographic data for several generations of owl monkeys, covering more than 330 individuals -- none of the individuals, regardless of their sex, reproduced in the same group where they were born. In all cases, the researchers found, the animals either departed from their natal group or died before reproducing.

Do smells prime our gut to fight off infection?      (via sciencedaily.com)     Original source 

In nematodes and humans, mitochondrial stress in the nervous system initiates a whole-body response that is most pronounced in the gut. A recent study showed that in nematodes, the odor of a pathogen triggers the nervous system to broadcast this response to the rest of the organism, prepping mitochondria in intestinal cells to fight a bacterial infection. Humans, too, may be able to sense pathogenic odors that prepare the gut for an infection.
