Sea peach fluorescence
Sea peaches (Halocynthia aurantium) are of the order Stolidobranchia, making them a sub-classification of Tunicates. Sea peaches are commonly found in the northern Pacific ocean, ranging from the Arctic Sea south to Puget Sound, and most common in the Bering Sea at a depth of 40 to 100 metres. The sea peach is typically barrel shaped, growing to a height of 18 centimeters, and its body is attached directly to the substrate. It is usually red or orange with a smooth or wrinkled tunic. There are two siphons at the top. The sea peach is preyed upon by crabs and sea stars.

Artistic microscope slides produced in the Victorian era (1840~1900) by arranging hundreds of tiny diatoms into intricate patterns. This was often accomplished by using a single hair to move the diatoms in a special chamber that prevented disturbance to the slide. The fabrication of these amazing objects must have required incredible patience, attention to detail, and a steady hand.
So i made a sciency crossword for you guys, hope you like it. You can print a full page one here - https://crosswordlabs.com/pdf/science-crossword356
Tell me if its too hard/too easy and ill adjust the next one (if you guys want a next one, that is.) There should be 3 or 4 that are easy to get, just to give you some letters for the others.
Also - the semicolon in the clue for 12 down means that “___-chemistry” and “Natural” are two separate clues for the same word.
Answers - Dont cheat!
Recent research indicates that the bumblebee is capable of flight past the highest point in the world! So how is this possible?
Most insects are unable to due to thinning of the air, a lack of oxygen and an inability to generate lift. The bumblebee however has adapted to the thinner air at high altitudes; not by beating their wings faster, but by swinging their wings through a wider arc. This means they are able to displace more air, generating enough lift to keep them a-flight at these high altitudes. Bees have a uneven muscle to body weight ratio which also helps them to fly in these incredible altitudes.
But why adapt this? There is no pollen on top of Mount Everest? Scientists believe that this is actually just a coincidence, all the adaptations correlate with pollen and nectar carrying. This is so bees can carry the maximum amount of pollen-sometimes twice their body weight! It also serves as a handy mechanism for escaping predators.
But that still doesn’t explain how they can breath in the limited oxygen supply and scientists are still trying to figure this one out.
Q:I try to make my blog a (mostly) science-oriented one, but it seems difficult to gain followers from the science-side of Tumblr. Unless you're a featured blog or something like that, it's easy to go unnoticed, even if you put a decent amount of effort into your posts. Got any advice on how to tap into the science community on here? It's more to give me an opportunity to continue to learn and present interesting ideas now that I've been graduated for a while than anything.
Tagging posts is a big thing athe first 5 tags i think it as actually show up in the tags so make those ones count. Following blogs that are similar to yours (they are obviously interested in the subject of your blog so a lot of them might actually check it out)
Going through science tags and liking/rebloging everything you like gets your blog noticed by other science blogs and its a good way to give credit to those that deserve it for doing exactly what you are doing.
You could also ask to be on shychemists master science blog list he is lovely and would add you to it :D
Also if any of you guys who follow me have a science blog you would want me to check out feel free to link me! I would love to follow and reblog some of your guys science blogs :)

The mask depicted above is hollow. One side is concave the other, convex. However despite how hard we try we can only see two concave faces. This is an optical illusion.
So why does this happen? The brain is said to have specific regions dedicated to processing faces. We know that faces are convex from our experience and knowledge so our brain processes it in a way that makes sense to us and matches our expectations.
This is so strong that it entirely over rides reality even when we are aware that what we are seeing is wrong, it is impossible to stop ourselves from perceiving it as a convex protruding face!
However this optical illusion actually fails to work on those with schizophrenia. This is to do with their unique way of processing information.
Thermal imaging of planes in flight taken by photographer Tyrone Turner at DC’s Reagan National Airport. The images show the varying degrees of heat emitted as the planes take off and land.
These were taken using a infrared camera the FLIR T640 which enables you to see this thermal activity.
Commonly known as Weedy Scorpionfish, Popeyed Scorpionfish or the Purple Tassled Rhino Scorpionfish, Rhinopias frondosa (Scorpaenidae) is a spectacular fish, very rare, but once found, can be easily located again as they tend to stay at the same place unless disturbed.
The colors will vary but they’re generally in red, purple, orangish hues. The specimen shown is purple variation.
Sawfly Larvae (Symphyta, Hymenoptera)
See more sawfly larvae images in my Flickr photostream HERE.
Sawfly is the common name for insects belonging to suborder Symphyta of the order Hymenoptera (wasps, hornets, bees and ants). Adult sawflies are wasp-like in appearance but are distinguishable from most other Hymenoptera by the broad connection between the abdomen and the thorax, and by their caterpillar-like larvae. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. Large populations of certain sawfly species can cause substantial economic damage to forests and cultivated plants.
Sawfly larvae look like caterpillars (the larvae of moths and butterflies), with two notable exceptions; (1) they have six or more pairs of prolegs on the abdomen (caterpillars have five or fewer), and (2) they have two stemmata (simple eyes) instead of a caterpillar’s six.

Stingrays are oviparous, laying eggs inside a protective hard case that’s commonly referred to as a “mermaid’s purse”. The embryos develop inside their cases for 3-5 months before hatching. They are cartilaginous fish, closely related to sharks and rays.
