Look Up Tonight! Saturn Is Big and Bright, With Rings Tilted Our Way

Look up tonight, June 14, and overnight into the early morning hours of June 15, and you’ll be able to see Saturn looming luminously in the evening sky. Bring a telescope and you might even be able to see its rings.

Tonight, Saturn is “at opposition”—that is, as close to the Earth as it's going to get this year, and therefore big and bright. It's because our orbits: We are presently in alignment with the Sun, and between it and Saturn, so from our perspective, the disc of Saturn is in full illumination. Think of it as a “full Saturn,” with the same general idea at work as when we have a full Moon.

So what are you waiting for? You’re not going to live forever. Grab a telescope and a blanket and get to the countryside. The Roman god of agriculture and wealth awaits!

HOW DO I SEE IT?

When you look at Mars through a telescope, you’re looking for the ice caps. When you look at Jupiter, you’re looking for its moons and gorgeous stripes. When you look at our Moon, you want to see the craters, ridges, and mountains along the terminator (the line dividing light and dark during the moon’s phases). Saturn, of course, is all about the rings.

Here is the good news: Any telescope of reasonable power should be able to see Saturn’s rings. (That $30 novelty telescope you bought your kid for Christmas that’s collecting dust in a closet? If it has 25x magnification—and it probably does—and if the sky is clear and light pollution low and you know what you’re doing, you can use that.)

Here’s the bad news: Saturn is smaller than Jupiter and a lot farther away from the Earth. Right now, even as it nears opposition, it's nine astronomical units away. (An astronomical unit is the distance between the Sun and the Earth.) This means you should prepare yourself for something less spectacular than Cassini-generated images. It’s going to be small. It’s going to be fuzzy. But it will be recognizable as Saturn, and it's a good year to try to spot its rings.

A good view of the rings is not always a guarantee. Some years, the rings are edge-on when seen through a telescope, making them appear more as a single flat line bisecting the planet than as actual rings circling an alien world. (Without enough magnification, the rings might seem to vanish entirely.) Other years, the rings are “open,” Saturn’s pole tilting our way, and you get that wonderful Glamour Shots pose, the rings 45-degrees forward and giving the camera all it’s got. This is because of the planet's orbit and tilts.

Why is it so important for you to get out there and check out Saturn tonight? Because 2017 is a “wide open” year. You’re going to see it all, and with enough telescope, you’ll even be able to make out the gap between the rings and the planet. Saturn will first creep over the southeastern horizon just after 9:30 p.m. EDT on June 14, and will reach its highest point in the sky around 1:30 a.m. This is the best time for viewing: a high, bright Saturn, due south and with rings aplenty. If you’re setting an alarm, give yourself a lot of time to set up and for your eyes to adjust to the darkness. The usual conditions apply: You need a clear sky and no light pollution.

If the weather is bad tonight or you have unbreakable plans, take heart: Saturn will look virtually identical tomorrow night—so much so that beginning at 8 pm EDT on June 15, Slooh is hosting a livestream of the planet featuring views from telescopes and live commentary by astronomers.

SOON THE ONLY WAY TO SEE IT

After September 15, the only way anyone will be able to see Saturn’s rings is to use a telescope, whether of the backyard or the Hubble variety. That’s because NASA’s Cassini spacecraft, which first arrived in the Saturnian system on July 1, 2004, will finally arrive at the end of its mission on that day. Cassini’s grand finale will see the spacecraft plunge into the mysterious atmosphere of the gas giant, where it will disintegrate, though not before returning data revealing the nature of the planet’s magnetosphere and surface winds, and providing some idea of composition of its core.

Cassini is at present still orbiting Saturn, though you will not be able to see the spacecraft with your telescope tonight, even if you do have access to Hubble.

New Program Trains Dogs to Sniff Out Art Smugglers

Soon, the dogs you see sniffing out contraband at airports may not be searching for drugs or smuggled Spanish ham. They might be looking for stolen treasures.

K-9 Artifact Finders, a new collaboration between New Hampshire-based cultural heritage law firm Red Arch and the University of Pennsylvania, is training dogs to root out stolen antiquities looted from archaeological sites and museums. The dogs would be stopping them at borders before the items can be sold elsewhere on the black market.

The illegal antiquities trade nets more than $3 billion per year around the world, and trafficking hits countries dealing with ongoing conflict, like Syria and Iraq today, particularly hard. By one estimate, around half a million artifacts were stolen from museums and archaeological sites throughout Iraq between 2003 and 2005 alone. (Famously, the craft-supply chain Hobby Lobby was fined $3 million in 2017 for buying thousands of ancient artifacts looted from Iraq.) In Syria, the Islamic State has been known to loot and sell ancient artifacts including statues, jewelry, and art to fund its operations.

But the problem spans across the world. Between 2007 and 2016, U.S. Customs and Border Control discovered more than 7800 cultural artifacts in the U.S. looted from 30 different countries.

K-9 Artifact Finders is the brainchild of Rick St. Hilaire, the executive director of Red Arch. His non-profit firm researches cultural heritage property law and preservation policy, including studying archaeological site looting and antiquities trafficking. Back in 2015, St. Hilaire was reading an article about a working dog trained to sniff out electronics that was able to find USB drives, SD cards, and other data storage devices. He wondered, if dogs could be trained to identify the scents of inorganic materials that make up electronics, could they be trained to sniff out ancient pottery?

To find out, St. Hilaire tells Mental Floss, he contacted the Penn Vet Working Dog Center, a research and training center for detection dogs. In December 2017, Red Arch, the Working Dog Center, and the Penn Museum (which is providing the artifacts to train the dogs) launched K-9 Artifact Finders, and in late January 2018, the five dogs selected for the project began their training, starting with learning the distinct smell of ancient pottery.

“Our theory is, it is a porous material that’s going to have a lot more odor than, say, a metal,” says Cindy Otto, the executive director of the Penn Vet Working Dog Center and the project’s principal investigator.

As you might imagine, museum curators may not be keen on exposing fragile ancient materials to four Labrador retrievers and a German shepherd, and the Working Dog Center didn’t want to take any risks with the Penn Museum’s priceless artifacts. So instead of letting the dogs have free rein to sniff the materials themselves, the project is using cotton balls. The researchers seal the artifacts (broken shards of Syrian pottery) in airtight bags with a cotton ball for 72 hours, then ask the dogs to find the cotton balls in the lab. They’re being trained to disregard the smell of the cotton ball itself, the smell of the bag it was stored in, and ideally, the smell of modern-day pottery, eventually being able to zero in on the smell that distinguishes ancient pottery specifically.

“The dogs are responding well,” Otto tells Mental Floss, explaining that the training program is at the stage of "exposing them to the odor and having them recognize it.”

The dogs involved in the project were chosen for their calm-but-curious demeanors and sensitive noses (one also works as a drug-detection dog when she’s not training on pottery). They had to be motivated enough to want to hunt down the cotton balls, but not aggressive or easily distracted.

Right now, the dogs train three days a week, and will continue to work on their pottery-detection skills for the first stage of the project, which the researchers expect will last for the next nine months. Depending on how the first phase of the training goes, the researchers hope to be able to then take the dogs out into the field to see if they can find the odor of ancient pottery in real-life situations, like in suitcases, rather than in a laboratory setting. Eventually, they also hope to train the dogs on other types of objects, and perhaps even pinpoint the chemical signatures that make artifacts smell distinct.

Pottery-sniffing dogs won’t be showing up at airport customs or on shipping docks soon, but one day, they could be as common as drug-sniffing canines. If dogs can detect low blood sugar or find a tiny USB drive hidden in a house, surely they can figure out if you’re smuggling a sculpture made thousands of years ago in your suitcase.

New Cancer-Fighting Nanobots Can Track Down Tumors and Cut Off Their Blood Supply

Scientists have developed a new way to cut off the blood flow to cancerous tumors, causing them to eventually shrivel up and die. As Business Insider reports, the new treatment uses a design inspired by origami to infiltrate crucial blood vessels while leaving the rest of the body unharmed.

A team of molecular chemists from Arizona State University and the Chinese Academy of Sciences describe their method in the journal Nature Biotechnology. First, they constructed robots that are 1000 times smaller than a human hair from strands of DNA. These tiny devices contain enzymes called thrombin that encourage blood clotting, and they're rolled up tightly enough to keep the substance contained.

Next, researchers injected the robots into the bloodstreams of mice and small pigs sick with different types of cancer. The DNA sought the tumor in the body while leaving healthy cells alone. The robot knew when it reached the tumor and responded by unfurling and releasing the thrombin into the blood vessel that fed it. A clot started to form, eventually blocking off the tumor's blood supply and causing the cancerous tissues to die.

The treatment has been tested on dozen of animals with breast, lung, skin, and ovarian cancers. In mice, the average life expectancy doubled, and in three of the skin cancer cases tumors regressed completely.

Researchers are optimistic about the therapy's effectiveness on cancers throughout the body. There's not much variation between the blood vessels that supply tumors, whether they're in an ovary in or a prostate. So if triggering a blood clot causes one type of tumor to waste away, the same method holds promise for other cancers.

But before the scientists think too far ahead, they'll need to test the treatments on human patients. Nanobots have been an appealing cancer-fighting option to researchers for years. If effective, the machines can target cancer at the microscopic level without causing harm to healthy cells. But if something goes wrong, the bots could end up attacking the wrong tissue and leave the patient worse off. Study co-author Hao Yan believes this latest method may be the one that gets it right. He said in a statement, "I think we are much closer to real, practical medical applications of the technology."
