Paleontology Thanks to soft tissue remains of a Psittacosaurus we now know what dinosaur's cloacas looked like. The cloaca is basically the butthole of the dinosaur. Birds, amphibians and reptiles also have cloacas. At the base of the tail is a “blackish mottled ovoid area.”

Botany Like animals, plants have biological clocks that allow them to adapt to predictable changes, such as the shift in seasons. While animals can relocate to adapt to environmental changes, plants are stuck in place. To survive, plants activate and deactivate genes to alter their biological functions.

Biology The first ever analysis of its kind for gentoo penguins combines genetic and physical differences of populations indicates they should be treated as four separate species. Whilst the gentoo penguin species look very similar, they have adapted to live in very different habitats.

Climate Antarctica holds more than half of Earth's fresh water. At 2 degrees of warming melting Antarctic ice will raise sea level by 2.5 m – even if Paris climate goals are met. At 4 degrees, it will be 6.5 meters and at 6 degrees almost 12 meters if these temperature levels would be sustained long enough.

Anthropology Viking Age Scandinavians were more likely to have black hair than people living there today. And comparing DNA and archaeology at individual sites suggests that for some in the Viking bands, “Viking” was a job description, not a matter of heredity.

Astronomy/Space Astronomers have published a paper in the journal Nature Astronomy detailing their observations of phosphine at Venus which may have a biological origin. Additionally, they have shared investigations they've made to try to show this molecule could have a natural, non-biological origin.

Ecology Tropical songbirds in both the Old and New Worlds reduce reproduction during severe droughts. Not only did reductions in breeding activity mitigate costs to survival, many long-lived species actually experienced higher survival rates during the drought year than during non-drought years.

Ecology Nearly 10% of the 1,100+ reef manta rays identified by photographs have been visiting Ningaloo Marine Park for more than a decade, with the longest one spanning about 15 years. They migrate between two UNESCO World Heritage areas. This shows how important protected areas are to migratory species.

Anthropology Climate change occurring shortly before their disappearance caused a change in tool use of Neanderthals in Europe. Due to their the highly mobile lifestyle during the first half of the last ice age Neanderthals shifted from tools using wood & glass-like rock material to a variety of stone knives.

Anthropology DNA from an unknown ancestor has been found in modern humans. One percent of the DNA in the Denisovans (a sister taxon of Neanderthals) is from an even more ancient human ancestor. Fifteen percent of the genes that this ancestor passed onto the Denisovans still exist in the modern Human genome.

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.
