Twinkly earthstars :Cornell Mushroom Blog. A post from your editor, Kathie Hodge, who’s fascinated by fungi that move. Aside: Recently I learned that the Library of Congress has added this blog to their historical collection of Science Blogs. I think that’s pretty cool. Thanks for coming along on the ride. Fungi are lively things, but (like this blog) you can seldom spot them moving. That’s why we like time lapse videos here on the Cornell Mushroom Blog, to hurry things along a bit. Our fungus of the day barely needs speeding up — pleasingly, it’ll do its thing while I share a cup of tea with visitors at my lab table.
There are two kinds of earthstars that look similar only because they’ve hit upon the same delightful solution for spore dispersal. I found my Astraeus earthstars among the dunes of Cape Cod, Massachusetts. Unlike you, perhaps, I didn’t wonder about what recipe to use for my Cape Cod earthstars (well past their prime; already open and full of powdery spores). What IS it doing, anyway? ReferencesC.

Sped-up video of ocean creatures is kind of terrifying. You know what? We take it back. Don’t save the oceans. There’s some really freaky stuff in there. This video consists of 150,000 shots of corals and sponges, compressed into less than four minutes.
A lot of the motion is intended for desedimentation, shaking off detritus like sand and fish excrement that threaten to bury them. At normal speed, it might take weeks for some of these changes to be obvious, but in the video the creatures judder alarmingly or throw tentacles at your face. Photographer Daniel Stoupin, who made the video, explains that we need to understand slow creatures if we want to save them: Difficulties in understanding “slow” marine life and interpreting its behaviour, unfortunately, are aggravated by its decline caused by human impact.
But frankly, we’re not sure anymore. How do pain relievers work? - George Zaidan. All those different brands, varieties, and strengths filling the shelves at the drugstore can give anyone a headache! While there may be a hundred different colored boxes and bottles on the shelf, Alice (of Go Ask Alice fame) explains the four basic types of non-prescription pain-relievers. One of the most strangest types of pain comes from hitting your “funny bone.” Mentalfloss writes that the "funny bone" is neither funny (when you whack it on the edge of a piece of furniture), nor a bone (whether you whack it or not). Where'd the name come from, and why is it so painful? Click here. What happens when you can’t feel pain? Community farming - it's not about food: Josh Slotnick at TEDxUMontana. Boyd Varty: What I learned from Nelson Mandela. Jack Russell Terrier And Jaguar Are Best Pals. Jack Russell Terrier and jaguar are inseparable friends A pint-sized Jack Russell terrier named Bullet and his buddy Jag (you guessed it, a jaguar) prove that even the greatest feline-canine differences can be overcome.
According to a video by Barcroft TV, Jag met Bullet when he was brought to South Africa's Akwaaba Lodge and Predator Park. The resort is home to many domesticated African cats that interact with guests. Bullet became a source of comfort to Jag in the new environment and they've been inseparable ever since. (Source) Jaguars are large, powerful animals with very strong jaws that can even bite through turtle shells.
They range in weight from of 124 – 211 pounds kg (56–96 kg) to length 4 feet to 6.5 feet (1.2 to 1.95 m). They have the shortest tails of any big cat. Although jaguars are often tawny-colored, they can vary from reddish-brown to black. The term "jaguar" comes from the Native American word "yaguar", which means "he who kills with one leap. " Simon Sinek: How great leaders inspire action. Florida Surfer Rescues Drowning Loggerhead Sea Turtle. On a good day, a surfer is one with the ocean waves. On a really good day, he’s a hero, too. Cocoa Beach, Florida -- A surfer came to the rescue of a loggerhead sea turtle that was tangled in fishing lines just south of the Cocoa Beach Pier this afternoon.
The turtle's flippers were so entangled that it could be seen gasping for air from the ocean's surface as it struggled to free itself from the mono-filament. Seeing the marine reptile in distress, a nearby surfer paddled over to help the sea turtle while risking a possible bite from the animal. Loggerhead sea turtles have a bite force so powerful, that they can easily tear through a conch shell - a mainstay of the turtle's diet. After a few minutes, the surfer had completely untangled the sea turtle and it swam away. Loggerheads are considered an endangered species and are protected by the International Union for the Conservation of Nature.

A MESSAGE FOR ALL HUMANKIND (The Greatest Speech Ever!!!) - Charlie Chaplin. Eye of the Leopard. Solar magnetism twists braids of superheated gas. A rocket-borne camera has provided some of the sharpest images yet of the Sun's corona, the hot layer of gas that extends more than a million kilometres above the solar surface. The corona is millions of degrees hotter than the layer of gas beneath it, but nobody knows precisely why.
"It's counter-intuitive for us here on Earth because as you go up in altitude, the temperature decreases," says Jonathan Cirtain, an astrophysicist at NASA's Marshall Space Flight Center in Huntsville, Alabama. Nature podcast Geoff Brumfiel hears from researcher Jonathan Cirtain why the Sun’s atmosphere is hotter than its surface. For decades, researchers have suspected that powerful magnetic fields are heating the corona. "The Sun's atmosphere is just jam-packed full of magnetic field," says Cirtain.
As the lines of those fields cross and twirl, the theory went, they push and pull the charged gas in the corona, giving it the energy that heats it up. A closer look.

The "solar suitcases" designed by We Care Solar are saving lives around the worldMany mothers, babies are dying because their health facilities lack reliable electricityOne of the solar kits also helped during a recent cholera outbreak in the Congo (CNN) -- Solar energy in a suitcase is an invention saving lives around the world in places that lack reliable electricity.
Dr. Laura Stachel discovered several years ago that many women and babies were dying during childbirth simply because there wasn't adequate light to treat them. So she and her husband came up with a portable solar energy kit to provide light and power when necessary. Since 2009, their nonprofit, We Care Solar, has given out nearly 250 free kits to medical facilities in Africa, Asia and South America. "A lot of the clinics don't have any electricity," Stachel said. On his first day with the kit, a doctor from the Congo delivered a woman with twins. CNN Hero: Dr. Want to get involved?

Ocean Energy Teams Compete for $16 Million Saltire Prize in Scotland. People have long dreamed of harnessing the tremendous power of the ocean's waves and tides. Off the jagged and wild coast of Scotland, a competition is now under way to demonstrate a practical means of capturing that vast renewable energy for electricity. Four United Kingdom companies are vying for the Saltire Prize, a £10 million (about $16 million) award offered by the government of Scotland, which boasts that 25 percent of Europe's tidal energy potential is surging off its shores.
The prize will go to the first company that can demonstrate a viable, environmentally friendly ocean power system in Scotland's waters. Learn more about the Saltire Prize in the video story below: The Saltire Prize was announced in 2008, building on the success of the $10 million Ansari X-Prize for commercial space flight. (Related: "Pictures: Immense, Elusive Energy in the Forces of Nature") In this new phase, four companies will deploy test devices in the roiling seas off northern Scotland.
Restoring Beauty | video | @GrrlScientist | Science. Beauty the bald eagle, Haliaeetus leucocephalus, after her prosthetic beak had been fixed into place.Image: screenshot. One morning in 2005, an adult female bald eagle was spotted whilst scrounging for food at a landfill in Alaska. Emaciated, she was starving to death in the midst of a bounty of food. A poacher had shot her in the face, shattering the upper mandible of her beak, leaving her with a useless stump. The damage left Beauty with just a small portion of her left upper beak and destroyed almost all of the right side.
The eagle was relocated to Birds of Prey Northwest, a nonprofit organisation located near Coeur d'Alene, Idaho. The unanimous expert opinion was the bird should be euthanized. One afternoon, as Ms Cantwell spoke of Beauty's situation during an educational presentation she was giving, they got lucky. "I think I can help you with Beauty if you are interested…. " he said.
