Glass eels typically refers to an intermediary stage in the eel’s complex life. The term typically refers to a transparent glass eel of the family Anguillidae. These are the freshwater eels that spawn in the ocean, and then enter estuaries as glass eels and swim upstream to live in freshwater during their juvenile growth phase. As the glass eels enter freshwater they start to become pigmented and are typically referred to as elvers. The elvers grow larger and are referred to as yellow eels, which are the juvenile stage of eels before their reproductive maturation begins.
The issue isn’t whether you should go to law school (or get an advanced degree in another field). It’s really about your vision of how you can contribute to the human endeavor and be happy about your role and existence as a member of the global society. Our generation, shaped by war and poverty, had a simpler mandate—do everything we can to earn a living and put our children in a better economic footing. You have a much bigger mandate—save the world from its own excesses, ease the suffering of its inhabitants and make innovations to improve our state of being. It’s an ominous task! Once you figure out how you can help fulfill that mandate, the rest is easy…
One quick side-note, you mustn’t define a profession by dollars and cents or by a cost-benefit analysis. A janitor who is committed to his/her job can do more to advance the mandate than a medical researcher who lacks passion or ethics. You make a living by what you take, but you make a life by what you give. It’s not the degree, but what you do with it that counts.
Human hand versus tiger paw. A tiger’s front paws are large and strong to bring down prey. Their retractable claws can be pulled inside when this large carnivore walks. Tigers also mark their territory by scratching on trees, which conveniently also sharpens their claws.
Hot dang do I want a replica of that.
Blond hair is usually seen as synonymous with Caucasian people. However, blond hair actually also regularly occurs among the Melanesian people of New Guinea and some Pacific islands. Melanesian blond hair is curly, and it appears straw-colored.
Yeah, and the gene responsible for blonde hair in Melanesian people is actually different to that of caucasian people!
Blonde hair evolved twice! How crazy is that!
did you know that the cast and crew of the movie Jaws became horrified at the results of their movie? fucking horrified at the mass hysteria they had caused
not only that, peter benchley regretted writing the original novel right up until his death, and spent his final years trying to raise awareness and reverse the impact jaws had on people’s perception of sharks, which his wife continues today
This is Duolingo, a language-learning website/app that deserves some serious recognition. It offers over 10 languages for English speakers, as well as courses for non-English speakers around the world, and they’re in the process of adding more.
But wait, I don’t want to do any more schoolwork! Not to worry little one, Duolingo is actually more like a game. You can compete with friends, and earn “lingots” (which are basically Duolingo money) to buy power-ups, extra activities, and bonus skills - like Flirting.
I’m already taking a language, what do I need this for?
It’s not really a secret that most school language courses (in America, anyway) suck and only teach you to speak the language at about a third grader’s level. Which is why Duolingo is so freaking awesome.
Teachers can’t give every student individualized attention, but Duolingo can. If you’re not learning the way you want to or as much as you want to in the classroom, Duolingo is a really great resource. It’s easy, tailored to you, and really effective.
Duolingo tracks your progress and reminds you when you haven’t studied for a while or need a refresher on something. Already semi-fluent in a language? No problem, just take a shortcut to more advanced subjects or test out of the lesson.
The lessons start with the basics (he, she, hello, thank you, etc) and move up to harder stuff. Duolingo focuses on vocabulary first, so you can learn the language and then the grammar that goes with it - much simpler than the system most schools use. It also tracks the number of words you’ve learned and how well you know them.
And you don’t even have to write out the flashcards!
Duolingo is perfect for reviewing everything you forgot over the summer or giving you the extra help you need. And if you’re trying to learn a language on your own, it’s fantastic - you don’t have to create your own lessons. Whether you’re trying to learn your second, third, or fifth language, I seriously recommend Duolingo.
Okay, what else?
Duolingo also has discussion boards, where you can ask for help with a hard lesson, make new friends, watch for updates, and share your achievements.
Even better is the Immersion feature. It won’t send you to Spain or France, but it’s pretty awesome. Duolingo takes real articles from the internet, which users translate. You can translate articles from your native language into the language you’re learning or vice versa, which gives you more experience and makes the Internet more universal.
You can suggest new languages and track Duolingo’s progress in creating new courses. Bilinguals (older than 13) can help to create these courses. Duolingo has a long list of courses that can be contributed to, like Punjabi, Hebrew, and Vietnamese. Oh, and Dothraki, Klingon, Sindarin, and Esperanto.
And the best part? IT’S COMPLETELY FREE.
If you love languages or just want to pass French class this year, USE DUOLINGO. Download the app and practice a language while you wait for the bus instead of playing Angry Birds!
Coolest app I’ve ever downloaded.
I can’t tell what my favorite part is, but it’s either
- scientists wasting budget and time to see if ants count their steps
- the idea to put ants on stilts
- there had to be a guy who made ant stilts and put them on the ants
- confused ants
Pulmonary alveoli seen under the microscope
An alveolus (plural: alveoli, from Latin alveolus, “little cavity”) is an anatomical structure that has the form of a hollow cavity. Found in the lung parenchyma, the pulmonary alveoli are the terminal ends of the respiratory tree, which outcrop from either alveolar sacs or alveolar ducts, which are both sites of gas exchange with the blood as well.

SUCH A BABY.
OKAY I have to drop some newly acquired knowledge, and maybe a lot of people already know this BUT LISTEN
Hippos are, like…real, living land whales. It’s been genetically proven that their closest relatives are NOT pigs as was once believed, but whales! Hippos even make whistles and clicks underwater to communicate as well as help them “see” in murky waters.
They also have some incredibly thick skin that is extremely difficult to cut, and when they do get injured their skin secretes a special fluid that acts like a natural antibiotic ointment that prevents infections and speeds up the healing process. And this fluid turns blood red when it meets the air, so it looks pretty badass, too.
Also, the bones in their limbs are SOLID. There is no marrow, no hollow space, they are 100% BONE, MOTHERFUCKER. It helps weigh them down in the water so they can more easily submerge, and it helps support their weight on land. These bones can withstand the impact of a running hippo, and they aren’t slow, either!
Hippos are also responsible for more human deaths annually than crocodiles or other predators like lions and so on. Because they don’t take no shit, bro.
HIPPOS ARE REALLY FREAKING COOL, YOU GUYS.
*whispers* the number one cause of baby hippo deaths is adult male hippos
That’s because somewhere between that adorable squishy above and adulthood, they become one of the most aggressive animals on earth.
The pollinators were all over the common milkweed plants in my yard this weekend, including this honeybee (Apis mellifera). If you look closely on the largest version of the photo, you can see the milkweed pollinia (masses of pollen grains) attached to the honeybee’s back legs.
