We've all been there: Banging the back of a glass ketchup bottle, begging it to give you a dollop of the good stuff or battling with a plastic bottle coercing it into giving up the last of its contents.

Maybe that will be a thing of the past.

Six MIT researchers say they've solved that problem as part of an entrepreneurship competition. The result is a bottle coated with "LiquiGlide," a non-toxic material so slippery that the ketchup or for that matter mayonnaise just glides out when you turn it over.

Here's a video from Fast Company:

Here's what the students told the magazine:

Infections with the bacterium Clostridium difficile hit record numbers in recent years. Now there's evidence the hard-to-treat infections are becoming a problem for children.

The infections often strike the elderly, especially those who've been taking antibiotics that clear out competing bacteria in people's intestines. People sickened by the bug have persistent diarrhea that can, in severe cases, lead to dehydration.

Fossil-hunting scientists are coming to grips with a new discovery that could change forever how we think of dinosaurs. What they've found is that dinosaurs may well have been tortured by large, flealike bloodsucking insects.

Yes, it appears that the greatest predators that ever roamed Earth suffered just as we mammals did — and as we still do. Fleas were thought to have evolved along with mammals — they like our soft skins and a diet of warm blood.

But now scientists in China have discovered Pseudopulex jurassicus and its equally tyrannical cousin, Pseudopulex magnus — magnus as in "great."

A new study has some reassuring news about how fast Greenland's glaciers are melting away.

Greenland's glaciers hold enough water to raise sea level by 20 feet, and they are melting as the planet warms, so there's a lot at stake.

A few years ago, the Jakobshavn glacier in Greenland really caught people's attention. In short order, this slow-moving stream of ice suddenly doubled its speed. It started dumping a whole lot more ice into the Atlantic. Other glaciers also sped up.

As you can probably tell, at least one person on this blog's masthead likes ants.

So we've always been bummed that we haven't had the opportunity to tell you about zombie ants, but today we are glad to report there is a new development in the field. Luckily, it's a good-news report about a fungus that limits the fungus that turns ants into zombies.

Tonight is a good night for a meteor shower. The Lyrids aren't known for their flashy shows, but this year they're getting help from a new moon.

The dark skies will be "ideal for meteor watching from the ground," NASA says.

Kelly Beatty, senior contributing editor for Sky and Telescope magazine, tells Weekend Edition host Scott Simon the best views are from the darkest places.

"For every bright [meteor] you see, there will be many more faint ones, and to see the faint ones, you need a dark sky," he says.

The relatively feeble light of a new moon will help hopeful meteor-watchers across the continent.

Psychologists at Purdue University have come up with an interesting twist on the old notion of the power of positive thinking. Call it the power of positive perception: They've shown that you may be able to improve your golf game by believing the hole you're aiming for is larger than it really is.

Jessica Witt, who studies how perception and performance are related, decided to look at golf — specifically, how the appearance of the hole changes depending on whether you're playing well or poorly.

Sometimes nature just throws you a loop. All your carefully laid plans, all your exquisite calculations, all your deeply held beliefs and expectations get blown away in the simple eloquence of real data from the real world. That is how Dark Energy made its appearance into the world of cosmology. Its not just that folks weren't expecting it. They were, in fact, expecting the very opposite.

The sun ejected two huge solar flares Tuesday, and NASA says that we here on Earth may notice the effects of magnetic fields and ionized gases that it estimates will arrive around 1:25 a.m. ET Thursday. So, if you detect some electronic interference — say, your GPS doesn't work right — blame it on the sun.

Scientists from Fermilab say they've basically "cornered" the elusive Higgs boson — that's the particle that some have nicknamed the "God Particle," because it would fill in the final blank of Albert Einstein's theory of the universe.

This is complicated stuff, of course, but essentially the scientists at Fermilab say they found a bump in their data that suggests the existence of the particle. That bump corresponds to the evidence scientists at the Large Hadron Collider have found.

Here's a bit of explanation from the Fermilab press release:

Every so often, pieces of heaven crash into Earth.

They can come from our own solar system, or millions of light years away. Few of us are lucky enough to get our hands on one of these space rocks. But for meteorite hunters and dealers such as Ruben Garcia, touching a piece of outer space is a daily routine.

The Best Hunting Grounds

One of Garcia's favorite spots to go meteorite hunting is an enormous dry lake bed in southern Arizona.

This lovely image of the spiral galaxy ESO 510-13 was featured on Friday's Astronomy Picture of the Day.

A galaxy is a collection of billions of stars (gas and dust and lots of Dark Matter) held together by their mutual gravity. The exquisite warp seen here is likely caused by interactions with other galaxies. Collisions or "harassment" between galaxies is quite common and may be the most important process shaping galactic evolution.

Our brains are filled with billions of neurons, entangled like a dense canopy of tropical forest branches. When we think of a concept or a memory — or have a perception or feeling — our brain's neurons quickly fire and talk to each other across connections called synapses.

How these neurons interact with each other — and what the wiring is like between them — is key to understanding our identity, says Sebastian Seung, a professor of computational neuroscience at MIT.

This headline in the February 17th issue of The Chronicle of Higher Education caught my attention, After a Death, A Question: Are Students Hard-Wired for Hazing?

The death mentioned is that of Robert Champion, the Florida A&M band student who, in November 2011, died after his fellow band members allegedly beat him brutally as part of a long tradition of hazing.
