Weizmann Institute scientists develop ‘sniff test’ that predicts recovery of consciousness in brain
If an unconscious person responds to smell through a slight change in their nasal airflow pattern – they are likely to regain consciousness. This is the conclusion from a new study conducted by Weizmann Institute scientists and colleagues at the…

COVID-19 related strokes, other neurological impact under study
Traditional stroke treatments like clot-dissolving tPA and surgical removal of big clots in the brain are good choices as well when the stroke results from SARS-CoV-2 infection, investigators report. Excessive blood clotting and stroke — even in young, previously healthy…

Exploring why some COVID-19 patients lose their sense of smell
Doctors have reported that partial or total loss of the sense of smell is often an early symptom of infection with SARS-CoV-2, the virus that causes COVID-19. Now, researchers reporting in ACS Chemical Neuroscience have shown that in mice, two…
How to tune out common odors and focus on important ones
“Imagine a dog playing in a garden and smelling all of these different flowery smells, and then somewhere in the distance a predator appears, like a fox. The raw input coming into the dog’s nose is a smell that consists…

Detecting aromas in aged cognac
For connoisseurs of wines and spirits, part of the enjoyment is noting the various flavors and scents that are revealed with each sip. Aging transforms alcohol’s aroma further, especially in cognac, a type of twice-distilled fortified wine. Now, researchers reporting…
Artificial sweeteners combined with carbs may be more harmful than those sweeteners alone
The influence of artificial sweeteners on the brain and ultimately metabolism has been hotly debated in recent years. Some studies have found adverse effects on blood sugar and insulin levels, while others have not. In a study publishing March 3…
Yale study may help resolve bitter debate over low-cal sweeteners
Several studies in recent years have reported that low-calorie sweeteners in foods and beverages disrupt the human metabolism, promoting the development of diabetes and obesity. But other studies have found that consuming low-calorie drinks and food has little impact on…

Typical olfactory bulbs might not be necessary for smell, case study suggests
Our sense of smell depends on the transmission of olfactory information from the nose to the olfactory bulb in the brain through the olfactory nerve. And without olfactory bulbs, smell isn’t possible–or so scientists thought. A team of researchers have…
