A New Scale Can Measure the Weight of a Single Cell

Researchers in Europe have invented a new hypersensitive scale that can be used to measure fluctuations in living cells in real-time, Digital Trends reports. The Cytomass Monitor can measure the weight of a single cell weighing only two or three nanograms. (A nanogram is one billionth of a gram.)

Developed by researchers at ETH Zurich, the University of Basel, and University College London, the Cytomass Monitor works by monitoring the changing resonant frequency of a cantilever.

A pulsing blue laser pointed at the microscopic cantilever causes it to oscillate. When the cantilever—made sticky by collagen or a binding protein called fibronectin—picks up an individual cell, researchers can determine its weight by the way that the resonant frequency changes, which is read by an infrared laser. The device is made to be placed directly on the plate of a microscope, so the user can also see and film the cells moving.

In a new study published in the journal Nature, the researchers use the super-sensitive scale to show that a mammalian cell's mass subtly fluctuates throughout the cell cycle. On a second-to-second basis, a living cell's weight fluctuates by between 1 and 4 percent of its total weight, they found.

A Swiss technology company called Nanosurf is now working to make the Cytomass Monitor commercially available so that it can be used in a range of biological and pharmacological research. You can see the concept illustrated in the video below.

This is not, however, the most sensitive scale ever built. In 2012, researchers created a scale capable of measuring the mass of a single proton.

Google Is Celebrating Friends's 25th Anniversary With Hilarious Easter Eggs

On September 22, the more-popular-than-ever show Friends turns 25 years old, and this pop culture milestone has generated all kinds of celebrations, like the release of Central Perk coffee, a LEGO set, a “How You Doin’?” T-shirt, a jewelry collection, a theatrical Friends marathon, and more. To properly prepare for the anniversary, you’ll probably want to head to Google to learn more about the show, right? Well, now the search engine giant is even getting in on the fun with some Friends-inspired Easter eggs. 

All you need to do is either Google your favorite character’s full name or the first name followed by “Friends.” Not to give too much away—it really is a nice surprise—but type in “Joey Tribbiani.” A pizza icon will appear under the Knowledge Panel (located beneath the picture) on the right side of the screen. Click on the pizza to see an animation, followed by one of Joey's most recognizable (and relatable) lines. To annoy coworkers, friends, family members, and/or anyone else in earshot, just keep clicking on the icon. 

But the best Easter egg pops up when you Google “Friends glossary.” At the top of the page, you'll get funny definitions for words like pivot, woopah, unagi, unfloopy, and plenty of other running jokes from the show. Between the glossary and the Easter eggs, you won’t be able to get “Smelly Cat” out of your head, but you'll at least wind up with a unique trifle recipe.

PopSockets Is Rolling Out a Line of Drink Holders

PopSockets have become something of a fidgeting consumer’s dream. The cute and accordion-esque accessory knob that attaches to phones allows for an improved grip and gives people something to noodle with. Now, the company is hoping you’ll recognize the value in having a PopSockets appliance for your hot and cold drinks.

The PopThirst Cup Sleeve and the PopThirst Can Holder resemble insulated sleeves you can purchase for beverages. But these sleeves have a socket for a PopGrip attachment, which you can thread between your fingers to make for a more secure grip. This might be beneficial in the car, where bumpy roads can prompt more spills.

Holding a drink with the PopGrip acting as a handle seems a little more precarious. Most people will not do this, but if they do, you will probably find the consequences on Instagram.

Since going on sale in 2014, PopSockets has become a phone accessory giant, moving 100 million units in 2018.

The PopThirst Cup Sleeve and Can Holder are both one-size-fits-all and retail for $15 each.
