The afternoon for our Laysan albatross nestling started with a quick feed from the male parent Kaluakane. What happened afterwards was a surprise; two banded non-breeding albatross (K405 and K256) were caught on the cam practicing courtship in front of our nestling. An un-banded non-breeder also joins in the dance. This clip shows highlights from the courtship, the entire event continued for almost 30 minutes.
This infographic shows you the insane scale of our solar system
by Ria Misra
You may have seen graphics comparing the objects in our solar system by size, but this visualization offers a slightly different spin on the theme, by comparing objects by their total mass. Plus, it also features 460 tiny versions of former planet Pluto bouncing off of Earth like a game of interstellar marbles.
The visualization is the work of astronomer Rhys Taylor, who also previously made a similar visualization comparing the size of the gas giants in our solar system by mass.
This is a story about a little hedgehog (voiced by Mariya Vinogradova) and his friend bear cub (voiced by Vyacheslav Nevinniy). The two would meet every evening to drink tea from the cub’s samovar, which was heated on a fire of juniper twigs…
Malayan or Sunda pangolin (Manis javanica) - Borneo rainforest
Pangolins, often called scaly anteaters, are covered in tough, overlapping scales. These burrowing mammals eat ants and termites using an extraordinarily long, sticky tongue, and are able to quickly roll themselves up into a tight ball when threatened.
Siew Te Wong videoed this female Sunda Pangolin in the rainforest of Borneo in a very rare occation.
Occupy’s ‘Strike Debt’ buys debt cheaply… then forgives it
Published on Nov 14, 2013
The Occupy Movement’s “Rolling Jubilee” is a celebration of finding a way for people to cheaply remove debt via crowdsourcing. For more than a year, the “Strike Debt” group has been buying consumer debt on a secondary market for pennies on the dollar, and then immediately forgiving the debt. The group has raised nearly $630,000, spent $400,000 and abolished more than $14.7 million in debt for almost 2,700 Americans. The Rolling Jubilee will take place in New York City and other cities on Friday. RT’s Meghan Lopez talks with Jacques Laroche, a Strike Debt activist, about the group’s accomplishments over the last year.
Popular Science: Watch a Crow Solve a Complex Puzzle
by Collin Lecher
Crows are smarter than great apes and about on par with a 5-year-old child. We know they (and similar birds) can already complete complicated tasks, like putting a stick through a tube to finagle out food. But in this BBC video, the New Caledonian crow, after thinking it over briefly, easily completes a multi-step puzzle.
I was not sure about the solution to this puzzle until very close to the end of the video. I choose to believe this says more about the crow than about me. Bravo, crow.
Honey Badgers: Masters of Mayhem airs Wednesday, February 19, 2014 on PBS. For more, visit www.pbs.org/wnet/nature Honey badgers do indeed enjoy honey and they have become a scourge to beekeepers, shrugging off countless stings as it breaks into their hives. As the Nature on PBS program details, beekeeper Guy Stubbs tries to devise a hive that will thwart them, but effective badger-proof hives prove difficult to design. When Stubbs is ready to field test his latest effort, he enlists Stoffel and Hammy, a younger female badger, to try their luck, and can’t believe it when his hopes are dashed yet again.
Alex Filippenko: “Dark Energy and the Runaway Universe”
We expected the attractive force of gravity to slow down the rate at which the Universe is expanding. But observations of very distant exploding stars (supernovae) show that the expansion rate is actually speeding up, a remarkable discovery that was honored with the 2011 Nobel Prize in
Physics to the teams’ leaders. Over the largest distances, the Universe seems to be dominated by a repulsive “dark energy” — an idea Albert Einstein had suggested in 1917 but renounced in 1929 as his “biggest blunder.” It stretches space itself faster and faster with time. But the physical origin and nature of dark energy, which makes up about 70% of the contents of the Universe, is probably the most important unsolved problem in all of physics; it may provide clues to a unified quantum theory of gravity.
About the Speaker: Alex Filippenko is the Richard & Rhoda Goldman Distinguished Professor in the Physical Sciences. His accomplishments, documented in about 700 research papers, have been recognized by several major prizes, and he is one of the world’s most highly cited astronomers. In 2009 he was elected to the National Academy of Sciences, and he shared part of the Gruber Cosmology Prize in 2007. He has won the top teaching awards at UC Berkeley and has been voted the “Best Professor” on campus a record 9 times.
In 2006 he was selected as the Carnegie/CASE National Professor of the Year among doctoral institutions, and in 2010 he won the ASP’s Emmons Award for undergraduate teaching. He has produced five astronomy video courses with “The Great Courses,” coauthored an award-winning textbook, and appears in numerous TV documentaries including about 40 episodes of “The Universe” series. An avid tennis player, hiker, and skier, he enjoys world travel and is addicted to observing total solar eclipses (11 so far).
The first in a series of 5 minute nature productions about wildlife in Cave Creek Canyon in the Chiricahua mountains of southern Arizona. This episode provides info about the Collared Peccary aka Javelina.
The coywolf, a mixture of western coyote and eastern wolf, is a remarkable new hybrid carnivore that is taking over territories once roamed by wolves and slipping unnoticed into our cities. Its appearance is very recent — within the last 90 years — in evolutionary terms, a blip in time…
In a multi-part series with the popular astrophysicist Neil deGrasse Tyson, Bill explores a variety of topics, including the nature of an expanding, accelerating universe (and how it might end), the difference between “dark energy” and “dark matter,” the concept of God in cosmology and why science matters…
Leopards may be smaller than lions and slower than cheetahs, but it is believed there are roughly ten times more of them than lions, tigers and cheetahs combined. How have they achieved this? The key to their success is their cunning, stealth, and adaptability. From South Africa to Sri Lanka, leopards live secretly, clinging to the shadows.
