The maximum life span is a theoretical number whose exact value cannot be determined from existing knowledge about an organism; it is often given as a rough estimate based on the longest lived organism of its species known to date. A more meaningful measure is the average life span; this is a statistical concept that is derived by the analysis of mortality data for populations of each species. A related term is the expectation of life. Life expectancy represents the average number of years that a group of persons, all born at the same time, might be expected to live, and it is based on the changing death rate over many past years.

The concept of life span implies that there is an individual whose existence has a definite beginning and end. What constitutes the individual in most cases presents no problem: among organisms that reproduce sexually the individual is a certain amount of living substance capable of maintaining itself alive and endowed with hereditary features that are in some measure unique. In some organisms, however, extensive and apparently indefinite growth takes place and reproduction may occur by division of a single parent organism, as in many protists, including bacteria, algae, and protozoans. In order to consider life span in such organisms, the individual must be defined arbitrarily since the organisms are continually dividing. In a strict sense, the life spans in such instances are not comparable to those forms that are sexually produced.

There is a brief period during which it is impossible to say whether an organism is still alive, but this time is so short relative to the total length of life that it creates no great problem in determining life span.

Some organisms seem to be potentially immortal. Unless an accident puts an end to life, they appear to be fully capable of surviving indefinitely. This faculty has been attributed to certain fishes and reptiles, which appear to be capable of unlimited growth. Without examining the various causes of death in detail, a distinction can be made between death as a result of internal changes (i.e., aging) and death as a result of some purely external factor, such as an accident. It is notable that the absence of aging processes is correlated with the absence of individuality. In other words, organisms in which the individual is difficult to define, as in colonial forms, appear not to age.

BRAIN EXPLOSION! Thanks, physicists. Read more: http://bit.ly/1SSG67L

Some websites that I use for geography [lessons + revision] - a mix of summary notes websites, statistics, geo-located data and other goodies :D enjoy! Hope you find something useful! 

I’ve only put my faves tbh but ** = I’ve used this a lot A LOT 

Scribd: honestly some docs on here are so useful for help structuring your own notes etc. [our teacher uses this one for example for the glossary]

**Sporcle: i use this to test my place knowledge! [i’ve linked you to the world one, but you can find other continent specific ones too]

[Alternative to above that I personally haven’t used much but it looks decent so]

World Mapper: Really cool maps and omg countries look so funny distorted heu heu (HONESTLY SO USEFUL AND VISUAL) [i’ve linked to the old site haha]

**Gapminder: I’ve linked you to the program itself [so so so good omg for global trends over time GENIUS] but Hans Rosling is a cinnamon roll go watch the videos too!!

Information is beautiful: I love infographics okay fight me on this. You could have a look at this one and oh here’s the blog and just have an explore tbh [there’s isn’t a huge number of infographics on here tbh it’s a shame but i guess they’re trying to sell the book so fair]

**Datashine (UK centric): UK Census 2011 info geo-located and ahhh it’s so useful 

they also have this one on commuting if you’re about that life

*******CIA World Factbook: ALL THE STATS! LIFESAVER! 10Q America! (that maths pun stop me pls) 

Generally amazing website that is succinct and you could probably find so much on here tbh

Quizlet: really useful resource!! flashcards!! i love this site!! (and there’s an app hehe) test yourself on case studies etc!!

[tip: you can duplicate ppl’s flashcards and edit them if there’s anything you want to add!] 

BBC bitesize ayyy for gcse peeps! (and in general too :) ) 

S-cool [linked again to the gcse site cuz that’s what was bookmarked but they have an a-level section too!] Some real concise notes tbh and may be useful even if you aren’t studying gcses/alevels! :) 

my other masterpost/ramble hybrids are all (there’s like 2 others lol) here and feel free to come rant at me (or just talk lel) if any links don’t work etc! 

in hindsight a better header for this would have been ‘resources i rely on way too much for geography’ (*´◡`) 

The astro-fashion-loving Internet collectively gasped when ESA’s Hubble twitter account posted three gorgeous gowns, by Czech designer Jirina Tauchmanova with only credit “Photo: Vasek”, which google thinks is a Canadian tennis player. For four long days I couldn’t find anymore images, until, today! Which is why I’m sharing a belated #FashionFriday and #StarrySunday combo.

These gown were shown at Serbia Fashion Week back in December 2015 as Jirina Tauchmanova‘s Spring/Summer 2016 collection – I hope that means they will be available for purchase soon!

I think I recognize at least two of the images, NGC 602 & 30 Doradus, but I’m going to have to see these in person to be sure, yes, definitely, and probably try them on, too.

Saturn’s hexagon

This colorful view from NASA’s Cassini mission is the highest-resolution view of the unique six-sided jet stream at Saturn’s north pole known as “the hexagon.” This movie, made from images obtained by Cassini’s imaging cameras, is the first to show the hexagon in color filters, and the first movie to show a complete view from the north pole down to about 70 degrees north latitude.

Would It Be A Bad Thing to Wipe Out A Species … If It’s A Mosquito?

Mosquitoes have a nasty reputation.

The species Aedes aegypti, for example, is currently responsible for spreading the Zika virus through the Americas and also infects humans with dengue fever, chikungunya and yellow fever.

This raises the question: Should there be an effort to get rid of Aedes aegypti for good?

“There’s been lots of debate in the last 10 years whether we should eradicate mosquitoes, or at least the 100 species or so that serve as disease vectors for humans,” says David Magnus, director of Stanford University’s Center for Biomedical Ethics. “If you look at the science, the majority [of scientists] think we could probably eliminate mosquitoes without too much harm on the environment.”
