Researchers at the George Washington University, together with researchers at the University of California, Los Angeles, and the deep-tech venture startup Optelligence LLC, have developed an optical convolutional neural network accelerator capable of processing large amounts of information, on the order of petabytes, per second. This innovation, which harnesses the massive parallelism of light, heralds a new era of optical signal processing for machine learning with numerous applications, including in self-driving cars, 5G networks, data-centers, biomedical diagnostics, data-security and more.

Global demand for machine learning hardware is dramatically outpacing current computing power supplies...

A comprehensive study from Uppsala University, involving more than 250,000 women, shows that oral contraceptive use protects against ovarian and endometrial cancer. The protective effect remains for several decades after discontinuing the use. The study is published in the journal Cancer Research.

Ovarian and endometrial cancer are among the most common gynaecological cancers, with a lifetime risk of just over 2 per cent. Endometrial cancer is slightly more common but as it has clearer symptoms and is therefore often detected at an early stage, the mortality rate is low...

Eating avocado as part of your daily diet can help improve gut health, a new study from University of Illinois shows. Avocados are a healthy food that is high in dietary fiber and monounsaturated fat. However, it was not clear how avocados impact the microbes in the gastrointestinal system or “gut.”

“We know eating avocados helps you feel full and reduces blood cholesterol concentration, but we did not know how it influences the gut microbes, and the metabolites the microbes produce,” says Sharon Thompson, graduate student in the Division of Nutritional Sciences at U of I and lead author on the paper, published in the Journal of Nutrition.

The researchers found that people who ate avocado e...

The type and abundance of bacteria found in the mouth may be linked to lung cancer risk in non-smokers, finds the first study of its kind, published online in the journal Thorax.

Fewer species and high numbers of particular types of bacteria seem to be linked to heightened risk, the findings indicate.

Around one in four cases of lung cancer occurs in non-smokers and known risk factors, such as second hand tobacco smoke, background radon exposure, air pollution, and family history of lung cancer don’t fully explain these figures, say the researchers.

The type and volume of bacteria (microbiome), found in the mouth has been associated with a heightened risk of various cancers including those of the gullet, head and neck, and pancreas.

And the researchers wanted to find out i...
