Why Are There No Snakes in Ireland?

There never were any snakes in Ireland, partly for the same reason that there are no snakes in Hawaii, Iceland, New Zealand, Greenland, or Antarctica: the Emerald Isle is, well, an island.

Drink Up: New Study Concludes Wine Can Offset Dementia

The study, which appears in Scientific Reports, shows that wine has an effect on one’s glymphatic function, or the way the brain removes toxins. To clear itself of damaging and accumulated proteins like tau and beta amyloid, which are often linked with dementia, the brain pumps in cerebral spinal fluid (CSF) to act as a flushing solution. All sorts of variables can influence the glymphatic system’s operation, including trauma, stroke, and excessive alcohol intake.

When researchers dosed the mice in the study with moderate alcohol—amounting to 2.6 drinks daily—the glymphatic system was more efficient, removing more waste and exhibiting less inflammation than the teetotaling control mice.

As is usually the case when it comes to booze, you can have too much of a good thing. When mice got the equivalent of 7.9 drinks daily, their glymphatic system grew sluggish until the overindulging was terminated.

“Studies have shown that low-to-moderate alcohol intake is associated with a lesser risk of dementia, while heavy drinking for many years confers an increased risk of cognitive decline,” lead study author Maiken Nedergaard, of the University of Rochester Medical Center, said in a press statement. “This study may help explain why this occurs. Specifically, low doses of alcohol appear to improve overall brain health.”

To summarize:

  • Wine = brain health
  • Three glasses a day = “low-to-moderate alcohol intake”
  • Science is great

Step Inside a 13th-Century Chapel Filled With Human Remains—Using Digital Models

In medieval Britain, if human remains were disturbed in the grave or disinterred, they would be removed from the cemetery and placed in what was called a charnel chapel, a religious structure that often had walls stacked high with human remains that temporarily lacked a proper resting place. Charnel houses were popular in England between the 13th and 16th centuries (and are still used in some countries). Only two original charnel chapels are undisturbed today in the UK. One, the Rothwell charnel chapel, is now becoming much more accessible to the public through digital modeling.

The Rothwell Charnel Chapel Project at the University of Sheffield is creating 3D models of the chapel so that other researchers and the public can explore the medieval room for themselves. The Rothwell site is the most complete charnel chapel in the UK—most were repurposed, dismantled, or buried during the Reformation—but it’s not a highly accessible site. Besides, the room is filled with the bones of hundreds of people, and visitors could pose a threat to its preservation…

By sharing their “digital ossuary” online, the team is making it easier for researchers to study the practice of charnelling in England and the role it played in medieval religious practices. And even if you have no stake in studying medieval religion in England, it’s still really fun to explore an underground room full of 13th-century skulls.

Snaffle, Soodle, Snudge: Wonderful Old Words for Walking We Should Bring Back

Now that spring is here, no matter how committed you are to cars, it’s hard to resist an occasional mosey or stroll. Whether you prefer ambling through the park or zigzagging down a busy sidewalk, this is a lovely time to hoof it. Lucky for us all, the history of English has plenty of rare or forgotten words for walking that will put a glide in your stride.

1. AND 2. SNAFFLE AND SOODLE

These fanciful-sounding words have no definitive origin: They probably just sounded right to someone who was sauntering, which is what they both mean. An Oxford English Dictionary (OED) example from 1821 describes someone “soodling up and down the street.”

3. NOCTAMBULATE

If you sleepwalk—or just like to stroll about after dark—you have a tendency to noctambulate, or walk around at night.

4. SNUDGE

The first sense of snudging refers to being cheap, stingy, miserly, and Scrooge-like. Such penny-pinching behavior isn’t associated with great posture, and perhaps that’s why the word later referred to walking with a bit of a stoop. An English-French dictionary from 1677 captures the essence of snudgery: “To Snudge along, or go like an old Snudge, or like one whose Head is full of business.” Snudging is a little like trudging.

Swiss Restaurant Offers Insect Cooking Class, Forces Uncomfortable Comparison to Crustaceans

Insects are a sustainable and healthy food source, Bern’s Löscher restaurant explains.

A Swiss eatery has bugs on the brain, and they’re hoping that patrons will bite. As Travel + Leisure reports, The Löscher restaurant in Switzerland’s capital city, Bern, is now offering classes to instruct people how to cook with insects.

Aside from the initial “ick” factor, insects are a sustainable, protein-packed food source, and cultures around the world—from Central Africa to Asia and Latin America—eat the tiny critters. To enjoy the taste of bugs, we need to rethink our relationship with them, Löscher’s manager, Andrea Staudacher, told Swiss news outlet 20 Minuten, according to The Local. “We associate prawns with food but not grasshoppers. However the two animals are very similar,” Staudacher said.

I can’t stop looking at these scientific Images from the Wellcome Image Awards

From Mental Floss:

Each year, the Wellcome Image Awards highlight some of the most fascinating scientific images from around the world, as chosen by a panel of experts from the fields of science communications and medicine.

ZEBRAFISH EYE AND NEUROMASTS

Ingrid Lekk and Steve Wilson, University College London

In this 4-day-old zebrafish embryo, a certain gene expressed in the lens of the eye and other parts of the visual system glows red when it’s activated. You can see the lens of the eye, the head, and neuromasts (those red dots around the rim of the image) glowing red, while the nervous system glows blue.

BLOOD VESSELS OF THE AFRICAN GREY PARROT

Scott Birch and Scott Echols

This image was created using a 3D reconstruction of a euthanized parrot. It models the system of blood vessels in the parrot’s head and neck down to the capillary level.

INTRAOCULAR LENS IRIS CLIP

Mark Bartley, Cambridge University Hospitals NHS Foundation Trust

Iris clips can treat nearsightedness, cataracts, and other eye issues. This photo shows an iris clip fitting on the eye of a 70-year-old patient. He regained nearly all his vision after the surgery.

BRAIN-ON-A-CHIP

Collin Edington and Iris Lee, Koch Institute at MIT

Researchers are developing ways to grow miniature organs on plastic chips in order to make drug testing more efficient. Instead of testing pharmaceuticals on people, scientists may one day test them on something like this—neural stem cells grown on a synthetic gel.

#BREASTCANCER TWITTER CONNECTIONS

Eric Clarke, Richard Arnett and Jane Burns, Royal College of Surgeons in Ireland

Here is a visualization of discussions on Twitter using the hashtag #breastcancer. Each dot represents a Twitter user, and its size is based on how many other dots (or nodes) it is connected to. Each line represents a relationship with another Twitter user, and the thicker the line, the more that relationship shows up in the data. This part of the visualization relates to trending data—one tweet retweeted thousands of times.

PIGEON THERMOREGULATION

Scott Echols, Scarlet Imaging and the Grey Parrot Anatomy Project

No, this isn’t just an avian parody of The Scream. It shows the network of blood vessels, visualized using technology created by the same researcher as the parrot image above, under the skin of a pigeon. This dense network allows pigeons to control their body temperatures.

MICRORNA SCAFFOLD CANCER THERAPY

João Conde, Nuria Oliva and Natalie Artzi, Massachusetts Institute of Technology (MIT)

Because microRNAs control the function and growth of cells, they have a lot of potential in cancer therapies. MIT researchers are working on a system that could deliver these short genetic sequences to cancerous cells. It consists of two microRNAs woven like a net with a synthetic polymer.

DEVELOPING SPINAL CORD

Gabriel Galea, University College London

This image shows a mouse’s neural tube, the structure from which the spinal cord develops. In each of the three images, the blue color draws attention to a specific tissue type. In the left image, the blue is the neural tube itself, which forms the brain and spine. In the middle, the blue is the mesoderm, which will become the inner organs. On the right, the blue shows the surface ectoderm that becomes hair, skin, and teeth.
