One key objective of electronics engineering research is to develop computing devices that are both highly performing and energy-efficient, meaning that they can compute information quickly while consuming little power...

New research sheds light on how the “hell planet” got so devilishly hot and how other worlds might become too toasty for life. That rocky world, 55 Cnc e (nicknamed “Janssen”), orbits its star so closely that a year lasts just 18 hours, its surface is a giant lava ocean, and its interior may be chock-full of diamond.

The fresh insights come thanks to a new tool called EXPRES that captured ultra-precise measurements of the starlight shining from Janssen’s sun, known as Copernicus or 55 Cnc...

Bacteria known to cause oral infections may also be a contributory factor in patients developing potentially life-threatening abscesses on the brain, new research has shown. The study, published in the Journal of Dentistry, investigated brain abscesses and their association with bacteria that occur in the oral cavity. While this type of abscess is relatively uncommon, it can result in significant mortality and morbidity.

Researchers examined the records of 87 patients admitted to hospital with brain abscesses, and used microbiological data obtained from abscess sampling and peripheral cultures.

This allowed them to investigate the presence of oral bacteria in patients’ brain abscesses where a cause of the abscess had either been found, as was the case in just 35 patients, or not...

Different light spectra serve different needs for agrivoltaics. People are increasingly trying to grow both food and clean energy on the same land to help meet the challenges of climate change, drought and a growing global population that just topped 8 billion. This effort includes agrivoltaics, in which crops are grown under the shade of solar panels, ideally with less water.

Now scientists from the University of California, Davis, are investigating how to better harvest ...
