Brain inspires more robust AI

Most artificially intelligent systems are based on neural networks, algorithms inspired by biological neurons found in the brain. These networks can consist of multiple layers, with inputs coming in one side and outputs going out of the other. The outputs can be used to make automatic decisions, for example, in…

Mitochondrial genome editing technique yields useful traits

North Carolina State University researchers have successfully transferred an important gene from one compartment of a plant cell to another to produce tobacco plants that lack pollen and viable seeds, while otherwise growing normally. Their findings could lead to better ways of producing hybrid seeds to maximize crop productivity, or…

Newly discovered trigger of Parkinson’s upends common beliefs

A new Northwestern Medicine study challenges a common belief in what triggers Parkinson’s disease. Degeneration of dopaminergic neurons is widely accepted as the first event that leads to Parkinson’s. But the new study suggests that a dysfunction in the neuron’s synapses — the tiny gap across which a neuron can…

New ways to predict outcomes of pregnancies with fetal growth problems

A team of scientists, led by researchers at UCL, have developed new methods to predict outcomes for pregnancies where there are issues with poor growth of the baby inside the womb. The research, published in the Journal of Clinical Investigation, involved 142 women from the EVERREST Prospective Study who had…

Brilliant galaxies of early universe

Rochester Institute of Technology scientists have once again used data from the James Webb Space Telescope (JWST) as part of the Cosmic Evolution Early Release Science (CEERS) Survey to change the way we think about the universe and its distant galaxies. Jeyhan Kartaltepe, associate professor in the School of Physics…

In major breakthrough, researchers close in on potential preeclampsia cure

Researchers from Western and Brown University have made groundbreaking progress towards identifying the root cause and potential therapy for preeclampsia. The pregnancy complication affects up to eight per cent of pregnancies globally and is the leading cause of maternal and fetal mortality due to premature delivery, complications with the placenta…

Making AI smarter with an artificial, multisensory integrated neuron

The feel of a cat’s fur can reveal some information, but seeing the feline provides critical details: is it a housecat or a lion? While the sound of fire crackling may be ambiguous, its scent confirms the burning wood. Our senses synergize to give a comprehensive understanding, particularly when individual…

Scientists take next big step in understanding genetics of schizophrenia

Genetically speaking, we are individuals different from each other because of slight variations in our DNA sequences — so-called genetic variants — some of which have dramatic effects we can see and comprehend, from the color of our eyes to our risk for developing schizophrenia — a debilitating psychiatric condition…

Cars, chlamydia and canines are biggest koala killers

A database tracking hospital admissions and deaths reveals the devastating impact cars, disease and dogs are having on the South East Queensland koala population. Professor Joerg Henning and his colleagues at The University of Queensland School of Veterinary Science have analysed data from the UQ-developed KoalaBASE. “Car strikes, dog attacks…
