Why is biodiversity important? | Human Nature - Conservation International Blog. Elephant near the Mara North Conservancy in Kenya. (© Jon McCormack) Humanity must stop the pace of wildlife extinctions — or face extinction, according to the United Nations. The world has two years to seal a new pact on wildlife protection, the head of the UN body on wildlife, the Convention on Biological Diversity (CBD), told The Guardian last week. In two days, the EU and 195 member nations of the CBD will gather for two weeks to try to stem the tide of species extinctions. Nothing less than humanity is at stake, observers say. “Biodiversity is life on Earth, and every extinction chips away at it, undermining the stability of the planet,” said Olivier Langrand, executive director of the Critical Ecosystem Partnership Fund (CEPF), which gives grants to organizations to conserve biodiversity hotspots.
But how exactly is biodiversity so important to humanity? Wildlife support healthy ecosystems that we rely on. 2. Donate to help protect biodiversity. 3. 4. Further reading. PFAF. 11 Mind-blowing Math Documentaries To Watch. While some might not automatically put math and documentary together, we’re able to recommend the following list. 1. Dimensions: A Walk Through Mathematics A film for a wide audience. Nine chapters, two hours of math, that take you gradually up to the fourth dimension. Dimension Two - Hipparchus shows us how to describe the position of any point on Earth with two numbers... and explains the stereographic projection: how to draw a map of the world. Dimension Three - M.C. The Fourth Dimension - Mathematician Ludwig Schläfli talks about objects that live in the fourth dimension... and shows a parade of four-dimensional polytopes, strange objects with 24, 120 and even 600 faces!
Complex Numbers - Mathematician Adrien Douady explains complex numbers. Fibration - Mathematician Heinz Hopf explains his "fibration". Proof - Mathematician Bernhard Riemann explains the importance of proofs in mathematics. 2. Our world is built on numbers and the first of these was the number 1. 3. 4. 5. 6. 7. 8. 9. What May Become of Homo sapiens. When you ask for opinions about what future humans might look like, you typically get one of two answers. Some people trot out the old science-fiction vision of a big-brained human with a high forehead and higher intellect.
Others say humans are no longer evolving physically—that technology has put an end to the brutal logic of natural selection and that evolution is now purely cultural. The big-brain vision has no real scientific basis. The fossil record of human skull sizes over the past several thousand generations shows that our days of rapid increase in brain size are long over. Accordingly, most scientists a few years ago would have taken the view that human physical evolution has essentially ceased. If giant brains are not in store for us, then what is? The Far and Recent Past Tracking human evolution used to be the province solely of paleontologists, those of us who study fossil bones from the ancient past.

Até pouco menos de uma década atrás, mudar o comportamento de uma pessoa com um transplante de fezes pareceria uma loucura.
E não é algo que ocorrerá amanhã, mas as pesquisas com animais sugerem que talvez não seja uma ideia tão descabida. O que é averiguado nos laboratórios sobre a influência das bactérias que vivem em nosso intestino indica que elas não desempenham somente tarefas fundamentais para a saúde de nosso estômago. Influem também no estado do cérebro. Essas bactérias já foram transplantadas experimentalmente em humanos para combater infecções intestinais e da mesma forma, através da dieta e alimentos probióticos, que incluem microrganismos, serviriam para tratar doenças psiquiátricas e neurológicas.
Várias experiências com animais, principalmente ratos de laboratório criados em condições muito controladas, mostraram que os microrganismos do intestino podem afetar seu comportamento e modificar o equilíbrio químico de seu cérebro.

Da Filosofia da Ciência do Caos (Deleuze & Guattari) | Questões Cosmológicas. “A natureza usa um fio muito longo para tecer suas tramas – mas…apenas um pequeno pedaço do tecido… já revela toda a organização de sua tapeçaria.”
(Richard Feynman) Filosofia e ciência seguem 2 vias opostas; conceitos filosóficos têm por consistência ‘acontecimentos’; enquanto as funções científicas têm como referência ‘estados de fase’ – ou seja, enquanto a filosofia é ‘sintagmática’; ciência é ‘paradigmática’. A filosofia busca no interior destes estados acontecimentos emblemáticos; enquanto a ciência atualiza – por funções – tais fatos, por sobre um ‘estado de coisas’ referencial. A filosofia procede sob um plano conceitual de imanência; e a ciência atua sobre um sistema funcional de referência. Na ‘imanência conceitual’ filosófica…temos um conjunto unificado de variações sob a influência de uma ‘razão contingente’ — enquanto na ‘referência funcional’ científica, um conjunto de variáveis independentes atua sob controle de uma ‘razão necessária’.

The man who can map the chemicals all over your body. Sandy Huffaker Pieter Dorrestein's methods could reveal what microbes do in complex communities. Apart from the treadmill desk, Pieter Dorrestein's office at the University of California, San Diego (UCSD), is unremarkable: there is a circular table with chairs around it, bookshelves lined with journals, papers and books, and a couple of plaques honouring him and his work. But Dorrestein likes to offer visitors a closer look. On his computer screen, he pulls up a 3D rendering of the space.
Four figures seated around the table — one of whom is Dorrestein — look as if they've been splashed with brightly coloured paint. To produce the image, researchers swabbed every surface in the room, including the people, several hundred times, then analysed the swabs with mass spectrometry to identify the chemicals present. The picture reveals a lot about the space, and the people in it. Then there were signatures of the office's other inhabitants: the microbes that reside on human skin. Rock and roll. Team:Cambridge-JIC/Make Your Own - 2015.igem.org. FAQs What’s the difference between manual and motorised modes? The microscope has 3 knobs: two of them are used to pan across the sample, and one is used to focus. In manual mode, these knobs are controlled by hand. In motorised mode, they are instead connected to stepper motors. This enables you to program your own panning/focusing routines, and to operate the OpenScope remotely: e.g. when it is in an incubator, or in a different lab.
What is the difference between bright-field, dark-field and fluorescence modes? Bright-field is the simplest of all imaging modes: just the sample, backlit by a white light source (LED).

“Esqueçam tudo o que aprenderam na escola sobre Matemática” Muitas pessoas, de diferentes gerações, dizem que odeiam matemática. Por que razão acha que isso acontece? Muita gente tem uma relação traumática com a Matemática. Uma das razões tem a ver com o facto de o ensino da Matemática, tal como é feito na grande maioria das escolas, dar demasiado ênfase à resposta. Em vez de se encorajar os nossos alunos a serem curiosos e a procurarem a resposta, nós exigimos que eles a deem. O ensino baseia-se quase exclusivamente em testes e em ver em quem é mais rápido a encontrar a resposta. E muitos sentem-se embaraçados e inferiores porque não conseguem fazê-lo. Porquê? Para a maioria das pessoas, a Matemática parece demasiado abstrata, sem aplicação prática... O que tem então de mudar no ensino? E tem de haver paixão por parte dos professores. O que pode dizer para fazer a Matemática mais atraente e apelativa?
Em que sentido? Está preocupado com o futuro? Os computadores conseguirão substituir-nos em quase tudo? Ecologia acústica: os sons podem servir para analisar a biodiversidade e a saúde de um habitat. A medida pode revelar alterações complexas em habitats que não são visíveis com medições realizadas por satélites ou fotografias Você sabia que formigas, larvas de insetos e anêmonas-do-mar criam uma assinatura sonora?
Cada ambiente selvagem no planeta, como a floresta amazônica, funciona como uma orquestra da natureza. Os ventos, insetos, répteis, anfíbios, pássaros, mamíferos e barulhos dos rios são instrumentos que têm seu papel na harmonia sonora dessas grandes composições. Cada paisagem sonora gera uma assinatura única e contém uma quantidade incrível de informação. Fotografias e imagens de satélite são ferramentas importantes para acompanhar o desmatamento, mas nem sempre é possível detectar a degradação parcial através dessas imagens, já a sonoridade do ambiente pode revelar muito mais sobre o equilíbrio da biodiversidade.
O que é ecologia acústica? Antes a técnica consistia em gravar a sonoridade de cada animal isolado, restringindo as pesquisas aos limites de cada vocalização. Get Shocked To See How Small Our Earth Is ? World's first pocket spectrometer lets you measure the molecular makeup of nearly anything | Inhabitat - Green Design, Innovation, Architecture, Green Building. SCiO is a new gadget that instantly measures the molecular fingerprint of just about anything you see, and it fits in your pocket. Want to know the alcohol content of that beer you’re about to slurp down or how many grams of sugar are in your apple? This mini spectrometer will tell you. Equipped with some of the capabilities of large, heavy laboratory spectrometers, but built around the kind of optics used in cell phone cameras, the SCiO measures the light reflected off any given object, breaks down its spectrum, and then sends that information to the cloud.
Consumer Physics‘ unique algorithms immediately interpret the resulting data and the results show up on your cell phone within 5 seconds on a 3G connection. Designed to empower you with knowledge of your environment, medicine, food, and a near-infinite number of things, the SCiO will also allow you to participate in building the world’s first database of matter. The product’s genius is (partially) in its built-in perpetuity.

(All images: William Chesleden's 'Osteographia, or The anatomy of the bones', Courtesy of the National Library of Medicine) Born in 1688, William Cheselden was a prolific surgeon, and was influential in legitimizing the field as a proper medical practice. As an anatomy lecturer, he was elected into the Royal Society in 1712, where he published his first illustrated work, The Anatomy of the Human Body. Because Cheselden made the unprecedented decision to publish in the vernacular, English, and not in Latin, as was customary for scientists at the time, The Anatomy of the Human Body became a wildly popular textbook among English medical students.
Throughout a career performing surgery, Cheselden became an expert in the safe removal of both bladder stones and eye cataracts—improving survival rates for the poor souls undergoing 18th century surgery across the board. A human skeleton surveying the confines of its illustration, with some bony accoutrements. Access to nature may be vital for mental health, study finds. Getting away from it all in the great outdoors has been a proven panacea for generations of city-dwellers, but a new study has quantified how access to nature could be a vital component in our overall mental health.
With more and more of us living in urban areas, researchers from Stanford University in the US wanted to investigate why urbanisation is associated with greater incidences of mental illness. In a controlled experiment, they looked at whether exposure to nature could influence depression levels and specifically ‘rumination’: repetitive thoughts focused on negative aspects of the self. The researchers took two groups of participants and led them on 90-minute walks through two very different kinds of environments.
One group walked across a grassland area populated with oak trees and shrubs, while the other group walked along the side of a heavily trafficked four-lane highway. Vidivodo.
