Forget curing cancer: Scientists have discovered the perfect way to break spaghetti

Yahoo Science News feed latest items - Thu, 08/16/2018 - 19:01

With all the incredible medical and technological advancements coming out of the scientific community these days you might not think that researchers would be spending time studying spaghetti, but you'd be wrong. In a new paper published in Proceedings of the National Academy of Sciences, MIT scientists explain how to correctly break strands of the stringy pasta in half.

If you've ever made spaghetti you'll be very familiar with this particular problem: Dry spaghetti strands don't fit perfectly in most stovetop pots. You can either drop them in at full length and let them hang over the edge as the bottom half goes soft to snap them in half, in which case you'll end up with a bunch of smaller pasta chunks and a metric ton of tiny spaghetti fragments that aren't good for much of anything.

Not wanting to pass up the opportunity to solve a problem, a duo of MIT researchers decided to test the mechanics that leads to dry spaghetti strands busting up into a million tiny chunks rather than two uniform halves. What they discovered is an issue that plagues many long, thin objects, and they've even come up with a solution.

"A well-known problem with direct implications for the fracture behavior of elongated brittle objects, such as vaulting poles or long fibers, goes back to the famous physicist Richard Feynman who observed that dry spaghetti almost always breaks into three or more pieces when exposed to large bending stresses," the researchers write.

The fix? Add a twist to the pasta as you bend it. A twisting motion of approximately 270 degrees seems to be the sweet spot. This helps to control the stress on the object and results in a much cleaner split. "Our experimental and theoretical results demonstrate that twisting enables remarkable fracture control by using the different propagation speeds of twist and bending waves," the team explains.

This all might sound a little silly, but the research has implications far beyond your dinner plate. The neat thing about experiments like this is that the knowledge gained can be used for other applications, and the results of the experiments can now be used as a foundation for better understanding the fracturing habits of other, slightly more important objects than spaghetti.

Venezuelans are concerned over the safety of a "twin" viaduct of the collapsed Morandi bridge in Genoa, Italy, after a fire on the concrete structure caused a major blackout. Designed by Italian structural engineer Riccardo Morandi, it predates by five years his 1967 bridge in Genoa that collapsed this week causing the death of 39 people.

Does Earth have more than one moon? Researchers propose ‘mini-moon’ theory

Yahoo Science News feed latest items - Thu, 08/16/2018 - 12:32

We've all been taught from a very young age that the Earth has just one natural satellite. The Moon is there, it's easy to see at night from just about anywhere, and for the most part it's a pretty neat little friend for our planet. Some other planets in our Solar System have lots and lots of moons, but we only have one... right?

A new study proposes that the Moon is actually just the biggest of Earth's satellites, and that other "mini-moons' do actually orbit our planet but are so tiny and come-and-go so often that we hardly ever notice them.

The research, which was published in Frontiers in Astronomy and Space Sciences, was conducted by an international team of astronomers who now say that tiny objects in space regularly swoop into orbit around Earth. They're small, only between one and two meters in diameter, but they do show up from time to time, and they could offer scientists a window into the life cycle of asteroids.

As the researchers explain, the first of these "mini-moons" was detected way back in 2006. It was the first time any natural object had been observed orbiting Earth, aside from the Moon itself, and it was clear that the rock was a rogue object which had simply been captured by Earth's gravity, but it was still a significant finding.

Scientists call these objects "TCOs" and "TCFs" which stand for "temporarily-captured orbiters" and "temporarily-captured flybys," respectively. As the names imply, these natural bodies don't remain in orbit around Earth for very long, but instead slingshot themselves back out into space soon after making their appearance in the sky. TCO complete at least one full orbit, while TCF sometimes just graze Earth before flying away at high speeds.

To date, just one TCO has been observed — the aforementioned mini-moon spotted in 2006 — but the researchers believe that new telescope technology will allow us to spot more and more of these objects on a regular basis. If that happens, astronomers can begin to study them in more detail and potentially use them as models for the movement of asteroids around our Solar System.

Please don't eat the world's oldest cheese

Yahoo Science News feed latest items - Thu, 08/16/2018 - 12:32

At what point is aged cheese too old to eat?  A group of archeologists probably asked themselves that question after discovering 3,300 year old cheese in the tomb of Ptahmes, the former mayor of Memphis — Egypt’s capital city at the time.  SEE ALSO: People are petitioning to drink the mummy juice from the probably cursed sarcophagus The team of scientists, led by University of Catania and Cairo University archaeologist Enrico Greco, found the cheese buried in an Egyptian tomb that was first unearthed in 1885, according to a study published in the journal Analytical Chemistry in July.  That said, this certainly isn't the kind of aged cheese you want to taste test. The cheese is also laced with a potentially deadly form of bacteria. The pyramids at the center of the necropolis of Saqqara in Egypt.Image: Khaled desouki/AFP/Getty Images"The material analyzed in this study is probably the most ancient archeological solid residue of cheese ever found to date," the study says. Drifting sands kept the necropolis where the cheese was found buried for more than a hundred years after its first excavation, but in 2010, Greco and his team uncovered the tomb again. The team of researchers found broken jars filled with a mysterious solid white substance as well as a fabric that might have been used to cover the jars.  A mysterious solid white substance in a broken jar turned out to be contaminated cheese.Image: University of catania/Cairo universityThe team then dissolved samples of the white substance and purified the proteins so it could be analyzed via processes called liquid chromatography and mass spectrometry.  Those chemical methods work in tandem to essentially separate molecules in the sample and analyze them.  The analysis revealed peptides associated with dairy products produced by cow milk and either sheep or goat's milk. Basically, it's really, really old, solid cheese.  A close up of the mysterious solid substance in the jar that turned out to be contaminated cheese.Image: university of catania/cairo universityBut really. Don't eat it. Further analysis found that the cheese was contaminated with a bacteria called Brucella melitensis that causes the potentially deadly disease brucellosis, which can cause a fever, stomach ache, cough, and other unpleasant symptoms.  If their analysis was correct, this would be the earliest known instance of this bacteria.  The actual mummified body of Ptahmes and the rest of his family still have not been found in the massive burial complex, but hey, at least we found the cheese.

Exclusive: U.S. seed sellers push for limits on Monsanto, BASF weed killer

Yahoo Science News feed latest items - Thu, 08/16/2018 - 12:25

America's two biggest independent seed sellers, Beck's Hybrids and Stine Seed, told Reuters they are pushing U.S. environmental regulators to bar farmers from spraying dicamba weed killer during upcoming summers in a potential blow to Bayer AG's Monsanto Co. Limiting spraying of the chemical to the spring season, before crops are planted, would prevent farmers from using the herbicide on dicamba-resistant soybeans that Monsanto engineered. The seeds are sold by companies including Beck's and Stine.

Boeing says it’ll expand its already-strong satellite portfolio with the acquisition of Millennium Space Systems, a California-based venture that specializes in small satellites for national security customers. Founded in 2001, Millennium had its first satellite, the 200-kilogram (440-pound) Rapid Pathfinder Prototype, launched in 2011 for the National Reconnaissance Office’s NROL-66 mission. Millennium says it provided more than six years of operations for three classified payloads. The privately held company was awarded a U.S. Air Force contract for a geosynchronous satellite system, based on its Aquila platform. It also won backing from the Defense Advanced Research Projects Agency for a class… Read More
