A Mobile APP-based, Customizable Automated Device for Self-Administered Olfactory Testing and an Implementation of Smell Identification Test
Chem Senses. 2023 Jun 30:bjad022. doi: 10.1093/chemse/bjad022. Online ahead of print.ABSTRACTOlfactory tests are used for evaluation of ability to detect and identify common odors in humans psychophysically. Olfactory tests are currently administered by professionals with a set of given odorants. Manual administration of such tests can be labor and cost intensive and data collected as such are confounded with experimental variables, which adds personnel costs and introduces potential errors and data variability. For large-scale and longitudinal studies, manually recorded data must be collected and compiled from multiple si...

Enduring Change Happens One Step at a Time
When I took the helm of JAMA Internal Medicine in 2009, I had a good idea of the path, if not a destination, for the journal. I wanted to strengthen evidence-based medicine, draw greater attention to unnecessary procedures, examine “conventional wisdom” with a critical eye, increase awareness of the sometimes worrisome incentive structures in the health care system, and provide valuable information (and a voice) to the most important constituency in medicine—the patients. My editorial guidance, in short, was much like my philosophy in clinical practice: if a procedure or therapy does not extend life or improve the qu...

News at a glance: Biggest lightning storm, regulating AI, and restoring Europe ’s ecosystems
ATMOSPHERIC SCIENCE Volcano triggered world’s most intense lightning storm The January 2022 eruption of an underwater volcano in Tonga produced the most extreme lightning storm ever recorded. The giant, electrically charged ash plume of Hunga Tonga-Hunga Ha’apai (above) spawned nearly 200,000 lightning flashes , researchers report this week in Geophysical Research Letters . At its peak, lightning struck about 2600 times per minute—more than twice the peak rate recorded in previous storms. The lightning included record-setting bolts up to 30 kilometers tall, and some of the...

Euclid telescope to seek source of dark energy —the biggest mystery in the universe
When the Euclid space telescope blasts off from Cape Canaveral in Florida early next month, it will embark on an unprecedented effort to survey 1 billion galaxies—and perhaps solve cosmology’s greatest mystery. The search will cover more than one-third of the sky and look back in time to galaxies shining when the universe was just one-quarter of its current age of 13.8 billion years. Although the task is immense, Euclid’s primary goal is surprisingly simple. The data it collects will be boiled down to a single number, denoted by w . And cosmologists are hoping, maybe even a bit desperately, that it is not �...

Ancient city razed by IS group yields new artifacts from the rubble
In 2015, the Islamic State group razed the ruins of the ancient Assyrian city of Nimrud, located 30 kilometers south of Mosul in modern-day Iraq. Wielding bombs and bulldozers, they demolished the city’s nearly 3000-year-old palace, temples, sculptures, and carvings in just a matter of days. Now, researchers sifting through the rubble have unearthed previously unknown artifacts from a ruined temple dedicated to Ishtar, the Mesopotamian goddess of love and war. Earlier this year, archaeologists from Iraq and the University of Pennsylvania discovered fragments of a large stone monument (pictured) that depict Ishtar a...
