There's nothing like a fresh, tangy glass of orange juice to go with your morning oatmeal. But if you've just brushed your teeth, you may find that the beverage tastes … less than delicious. So, why does toothpaste affect the taste of orange juice and other sweet breakfast (or midnight) snacks? It all boils down to what's happening with the taste receptors on our taste buds, Guy Crosby, a nutrition professor at the Harvard T.H. Chan School of Public Health, told Live Science. In a nutshell, a compound in toothpaste called sodium lauryl sulfate (SLS) alters the way we process certain tastes, at least temporarily. [Why Do Some People Hate the Taste of Beer?] But let's start with how we detect different tastes. If you touch your tongue, you'll notice that it's covered with bumps and mini-ridges. Each of these bumps is made up of taste buds, which in turn are made up of taste receptors. Our mouthshave between 2,000 and 4,000 taste buds in total, and each taste … [Read more...] about Why Does OJ Taste Bad After You Brush Your Teeth?

Microsoft's biggest problem around its Cortana digital assistant is perception. The Siri and Google Now competitor has a rich feature set, and while the focus is shifting from pure app-like experience to a more nuanced smart-OS, there's a lot of potential.

Amazon has proven that this problem is solvable, without much effort. A simple email Microsoft has a decent web presence for Cortana . Head to Microsoft.com/cortana, and you are directed to a page with tips on getting organized, working across devices, details on "her" valuable skills, and more.

Roseanne was canceled by ABC yesterday following a racist remark star Roseanne Barr tweeted about Valerie Jarrett, who was a senior adviser to President Obama. Following the cancellation, Barr tweeted out a long-winded apology, which included a claim that the damning tweet had been influenced by a dose of Ambien. Barr’s excuse prompted Sanofi, the pharmaceutical company that manufactures Ambien, to weigh in. People of all races, religions and nationalities work at Sanofi every day to improve the lives of people around the world. While all pharmaceutical treatments have side effects, racism is not a known side effect of any Sanofi medication.— Sanofi US (@SanofiUS) May 30, 2018 So the maker of a popular prescription sleep medication wants you to know that — presumably after rigorous, double-blind testing and absolutely not in relation to anything a right-wing celebrity might be tweeting — its medical product does not produce racism as a side effect. This … [Read more...] about Ambien manufacturer wants you to know its product does not make you racist
By Emily UnderwoodMay. 3, 2018 , 2:00 PM Getting old can be a real itch. In addition to having memory and muscle loss, many elderly people develop supersensitive skin that gets itchy at the lightest touch. Scientists don’t know what causes this miserable condition, called alloknesis, or how to treat it. Now, however, a study in mice has revealed a counterintuitive mechanism for the disorder: a loss of pressure-sensing cells in the skin. Although the findings have yet to be replicated in humans, the study raises the possibility that boosting the function of these cells could treat chronic itch in people, both young and old. Chronic itch is different from chemical itch, which occurs when the immune system reacts to a foreign substance, such as oil from a poison oak leaf or saliva in a mosquito bite. Instead, chronic—or mechanical—itch is usually triggered by light pressure, such as the brush of fibers from a sweater. The condition is maddening, and when people … [Read more...] about Why getting old gives you itchy skin
Stoners may not be as forgetful and absent-minded as the stereotype suggests. A new study finds that heavy marijuana users are just as good as everybody else at remembering tasks they need to do in the future. This ability, called prospective memory, is the brain's internal calendar, which keeps track of your to-do list — the appointment you have later in the day, the stop you want to make on your way home, medications you need to take every day and so on. But while forgetting to pick up milk is annoying, a lot more can go wrong when prospective memory fails: It's also what's thought to be responsible when a surgeon forgets to remove a surgical tool before closing up a patient or when a parent leaves a baby in a hot car. Heavy use of some drugs such as alcohol and opioids may impair prospective memory, but there isn't sufficient research on whether marijuana has similar effects, said David Diamond, a professor of psychology and molecular pharmacology at the University of South … [Read more...] about Does Marijuana Make You Forget to Remember?
