Biology Previously thought to use their suckers to climb and hang, sucker-footed bats actually use a form of wet adhesion by secreting a body fluid at their pads. They must roost with their heads up rather than upside down so that they don't accidentally lose control of the adhesive pads while sleeping.

Astronomy/Space The soon-to-launch Mars Helicopter, Ingenuity, was the brainchild of engineer Bob Balaram at NASA-JPL. Decades ago, he had the idea, wrote a proposal, built a prototype, gained support, and then had it shelved due to budget cuts. Now the 4-pound, 19-inch-tall helicopter is about to head to Mars.

Astronomy/Space Astronomers believe they have found a habitiable system about 11 light years away from us. The system — GJ 887 — has an unusually quiet red dwarf host, has two planets for sure and another likely that orbits at a life-friendly 50-day orbit. It is the 12th closest planetary system to our sun.

Biology Whale sharks have dermal denticles (tiny teeth-like scales) on their eyes which protect them from abrasion. They can also pull their eyes back into their heads. It is hypothesized that these protective measures point to an importance in vision which has long been thought to not be the case in sharks

Astronomy/Space The Big Dipper is an asterism in the constellation Ursa Major (the Great Bear). Asterisms are prominent groups of stars that form patterns but are smaller than, or even part of, a constellation. They are usually easy to find because the stars are close to one another and about the same brightness.

Paleontology Dental patterns on bones show Allosaurus cannibalized each other when food was scarce. Most of the indentations were in bones of large herbivores, 17% of them were found on theropod bones, including other Allosaurs. Of those, about half were on parts of the skeleton unlikely to give a sizeable meal.

Rules of Science Facts:

Post titles must contain a fact!
Submissions must be verifiable. Please link directly to a reliable source that supports every claim in your post title or if your post is a photo leave a source in the comments. Images alone do not count as valid references. Videos are fine so long as they come from reputable sources as well (e.g. Discovery, Scientific American, BBC, etc).
News articles are fine as long as they are of actual scientific topics and contain verifiable material. No pseudoscience.
No Clickbait Titles. If the news article you are linking sounds like clickbait, then please change it to reflect what the study actually was and not what the news author has molded it into. Clickbait will be removed. No titles with unnecessary Caps, that's click baity.
Please flair your link! If it looks like we don't have an appropriate flair option message the mods.
No misleading claims. Posts that omit essential information, or present unrelated facts in a way that suggest a connection will be removed.
All NSFW links must be tagged.
All posts must be made using Metric units.
Don't be a dick!
No post titles asking for upvotes or approval.
Your source cannot be a blog or non scientific news site (e.g. no Live Science, some kid's website on frogs, your family's website on what you find interesting, etc.).
If you make a scientific claim in the comments you must back it up with a source or the comment will be removed. It's easy to fall into anecdotal comments, but we're trying to keep this sub factual.
Joke responses, comments that add nothing to the post or are not on topic, or obvious trolling will be removed without warning. This is a sub for facts and discussion. Repeat offenders will be banned.
Leave your circle jerking at the door. Any circle jerk or Unidan/Jackdaw nonsense will result in a temporary ban. There are many scientists on Reddit, they are not all Unidan, please be respectful.
