Using machine learning, researchers at the UC Davis MIND Institute have identified several patterns of maternal autoantibodies highly associated with the diagnosis and severity of autism.
Their study, published Jan. 22 in
Molecular Psychiatry, specifically focused on maternal autoantibody-related autism spectrum disorder (MAR ASD), a condition accounting for around 20% of all autism cases. The implications from this study are tremendous, said Judy Van de Water, a professor of rheumatology, allergy and clinical immunology at UC Davis and the lead author of the study. It s the first time that machine learning has been used to identify with 100% accuracy MAR ASD-specific patterns as potential biomarkers of ASD risk.

Giant megatooth sharks – among the largest predators ever to exist on Earth – grew so large by feeding on the unhatched eggs of their siblings in the womb, new research suggests.
Also known as Megalodons, the now-extinct carnivores dominated the oceans 15 million to 3.6 million years ago, growing up to 50 feet (15 metres) in length.
According to a new study published in the journal
Historical Biology, they were typically already larger than most humans when they emerged from the womb, with a length of around 6.6 feet.
Megalodon gave birth to newborns as large as adult humans
The Megalodon babies likely ate unhatched eggs in their mother’s womb to come out on the hefty side.
Perhaps the fiercest shark that ever swam the world’s oceans was
Otodus megalodon, an extinct species of shark that lived from the early Miocene to the end of the Pliocene, from 23 to 2.6 million years ago.
Megalodon was the uncontested marine predator of ancient times, reaching 15 meters (50 feet) in length twice as long as the second-largest shark in history. Not surprisingly, Megalodon’s babies were also on the hefty side. According to a new study, Megalodon newborns were larger than most adult humans.
Measuring up to 50 feet in length, gigantic megalodon sharks were once the most fearsome predators to roam the oceans.
Now, a new study suggests that even their babies were absolutely huge at birth, with most measuring larger than an adult human.
Rather gruesomely, the researchers believe that the shark babies likely grew to this size by feasting on unhatched eggs in the womb.
Adult megalodons, which swam the Earth s oceans roughly 15 to 3.6 million years ago, reached at least 50ft (15m) in length.
According to the study, from the moment of birth, megalodon – formally called Otodus megalodon – was already 6ft 7in (2m) long.
