Little Spiders Have Huge Brains That Spill Into Their Legs | Discoblog | Discover Magazine
"Tiny spiders have enormous brains, so big the neurons spill into their legs, causing the spiderlings of some species to bulge like overstuffed brain-bags (although the bump fades with adulthood). In some small arachnids this extended brain—really just a tangled mass of nerves—takes up almost 80 percent of the animal’s body cavity, and about a quarter the mass of its legs. Talk about thinking on your feet. The percentage of space devoted to cognition dwarfs that of humans, whose brains take up two to three percent of the body. It also trumps the setup of minute beetles and ants, whose brains make up only 15 percent of their weight. These insights come from a study published recently in the journal Arthropod Structure and Development, which set out to explain why small spiders are basically as adept as large spiders when it comes to completing relatively complex tasks like building webs. These massive distributed brains, it turns out, may be the answer." - Eivind from Bookmarklet

""How many times do you estimate the eye has evolved?" "Tough to say but probably 40 times. Any audience reading this will know that evolution occurs in gradual steps, stops and starts, rather than just being fully formed. Some people have asked 'What is the use of half an eye?' and it can be quite useful. There is a shrimp that has a fully formed eye in its larval stage closer to the surface of the water and as it grows it sinks and when it is fully formed it no longer has an eye, it has less than half of an eye, really just a strip of retina, but it lets the shrimp detect IR and black body radiation and the risks from vents on the ocean floor."" - Eivind from Bookmarklet

Super Cool New H2O Discovered : Discovery News
"Besides vapor, ice and liquid, a fourth form of water may exist. But don't worry, Kurt Vonnegut fans, it's not ice-nine, the dangerous, solid-at-room-temperature substance from the book Cat's Cradle. Unlike the fictional ice-nine, which melted at 114 degrees Fahrenheit, this new form of H2O likes it cold: about 54 degrees below zero Fahrenheit. Liquid water usually freezes into ice at 32 Fahrenheit, but under the right conditions, like the high pressure at the bottom of the ocean, water stays liquid below 32 Fahrenheit. Water's fourth form, or phase, may be a liquid with some of the properties of both ice and regular liquid water. But laboratory equipment isn't sensitive enough to observe the rapid transformation from regular liquid water to the fourth form. Researchers Pradeep Kumar and H. Eugene Stanley used a computer simulation to model the elusive liquid. They found that at about 54 degrees below zero Fahrenheit, the local structure of water seems to become extremely ordered,... more... - Jenny from Bookmarklet

It's the most voluminous fresh water lake in the world, so if the 20% were surface area, which I'm pretty sure it's not, wouldn't it probably have more than 20% of the volume? - Eivind

"Male and female marsh harriers should be easy to tell apart: the males have grey wing-tips and tails, while the females are mostly brown with distinctive creamy heads. The males also tend to be around 30 percent smaller. But looks can be deceptive. In western France, many of the “female” harriers are actually cross-dressing males that permanently wear the plumage of the opposite sex. Audrey Sternalski has found that this unusual costume allows them to lead more peaceful lives." - Eivind from Bookmarklet
"The marsh harrier is one of only two birds whose males permanently don the colours of females. The other – the ostentatious ruff – also uses its disguise to avoid aggressive assaults. They sneak into the territories of more dominant males and surreptitiously mate with the resident females. Such strategies are fairly common in the animal kingdom – they’re found in ants, wasps, fish, and more. In most cases, the deceptive males get some sneaky sex, or avoid attacks from rivals." - Eivind

"Here are some factoids about these murine monsters, from an nice editorial accompanying the research paper in Nature. These critters live in underground colonies - because who could suffer to see them on the surface?. These bald rats are unique among mammals in that they are "eusocial" like bees or ants. Also like bees and ants, a colony has a single, breeding "queen" in the group, whose mere presence prevents other female mole rats from becoming sexually mature. When a queen dies, females fight for the vacant throne. When one wins and becomes the new queen, she subsequently undergoes a "growth spurt," becoming up to 80% heavier and dramatically lengthening her lower spine (Dengler-Crish and Catania 2007; figure below) - a marvel of phenotypic plasticity. These dwell in crowded, dirty tunnels low in light and oxygen; it's kind of like Los Angeles. Plus, they can live for up to 30 years, which is an amazingly long time for an animal you can hold in your hand. They are also apparently resistant to cancer and to some kinds of pain and itching. So, so strange." - Eivind from Bookmarklet
"I think the paper's final paragraph (p. 4) lays out nicely what's most important about research into the genome of this most ghastly rodent: "To summarize, sequencing and analysis of the [naked mole rat] genome revealed numerous insights into the biology of this remarkable animal. In addition, this genome and the associated data sets offer the research communities working in ageing,... more... - Eivind

"These small studs, arranged in grids and honeycombs, look completely unnatural. If the image was life-sized, you might think that they’re part of a bizarre children’s toy. If they had been photographed from far away, they might be buildings in an alien city. But they are neither. They have been intensely magnified; a thousand of them could fit across a human hair. They studs are part of the skin of a tiny insect-like creature called a springtail. They’re the secret behind its incredible waterproof shell. There are more than 7,000 species of springtail, and they’re among the most abundant animals that you can still see with the naked eye. Most are no bigger than a pinhead. They crawl through soil and leaf litter on six legs, and they leap about using a spring-like tail held under their body.

How the miracle fruit changes sour into sweet | Not Exactly Rocket Science | Discover Magazine
"Pop a “miracle berry” into your mouth, and you might wonder if it was named by an overreaching marketing department. The small red fruit tastes of very little – it has a “mildly sweet tang… [like] a less flavorful cranberry”. But it’s not the taste of the fruit itself that matters. To understand why the berry gets its name, you need to eat something acidic. The berries have the ability to make sour foods taste deliciously sweet. Munch one, and you can swig vinegar like it was a milkshake, or bite lemons as if they were candy. The secret to the fruit’s taste-transforming powers is a protein called miraculin. Now, Ayako Koizumi from the University of Tokyo has discovered just how the protein acts upon our tongues. Two groups of scientists independently isolated miraculin from miracle berries in 1968, but people have been experiencing its effects for far longer. West Africans have chewed miracle berries (Richadella dulcifica) before their meals for centuries, to get those unusual sweet... more... - Eivind from Bookmarklet

800-Mile-Wide Hot Anomaly Found Under Seafloor Near Hawaii -
800-Mile-Wide Hot Anomaly Found Under Seafloor Near Hawaii
"Scientists say they've found solid evidence of a giant mass of hot rock under the seafloor in the region. But it's not a plume running straight from the core to the surface—and it's hundreds of miles west of the nearest Hawaiian island. Until now, the researchers say, good seismic data on the region has been scarce, so it was tough to question the traditional explanation: that a stream of hot rock directly from around Earth's core formed the 3,100-mile-long (5,000-kilometer-long) chain of islands and undersea mountains in the Pacific Ocean. As Earth's crust slid over the plume, as if on a conveyor belt, the erupting seafloor built mounts, mountains, and islands out of layers of cooled lava over tens of millions of years—or so the conventional wisdom goes." - Jenny from Bookmarklet
"But after analyzing 20 years' worth of earthquake data, geophysicists say they've found an 800-mile-wide (1,300-kilometer-wide) region of hot rock in the Hawaiian region—but nothing beneath the Big Island of Hawaii. The island, the youngest in the chain, is traditionally thought to be above the purported plume. Although the new evidence flies in the face of the giant-plume theory, "we... more... - Jenny
"A technique called seismic tomography uses the sounds of earthquakes rippling through the planet and bouncing around to detect such plumes, or hot spots.

"What happens when you dump 8,000 fire ants into a tray of water? Nathan Mlot from the Georgia Institute of Technology wanted to find out. Mlot scooped the ants into a beaker, swirled it around to roll them into a ball, and decanted them into a half-filled tray. Over the next three minutes, the ball of ants slowly widened and flattened into a living, waterproof raft. By trapping air bubbles trapped among their interlocking bodies, the ants boosted their natural ability to repel water and kept themselves afloat. Humans build rafts by lashing together planks of wood or reeds; the fire ants do so by holding onto each other. The experiment might seem odd, but it mirrors conditions that the fire ant (Solenopsis invicta) regularly has to cope with in its natural environment. The ant hails from the Brazilian rainforest floodplains of Argentina, where rising water regularly submerges their nests. They respond by weaving their own bodies into rafts. The ants also come together to construct... more... - Eivind

"Europe may be starting to dive under Africa, creating a new subduction zone and potentially increasing the earthquake risk in the western Mediterranean Sea, scientists report. Subduction zones form where tectonic plates collide, with one plate diving beneath the other and into Earth's mantle. Sometimes these collisions are gradual, but often they occur in big lurches that can trigger quakes. Because subduction zones are generally on seabeds, earthquakes in these zones can set off tsunamis, like the killer wave that devastated Japan last month." - Jenny from Bookmarklet
"For millions of years the African plate, which contains part of the Mediterranean seabed, has been moving northward toward the Eurasian Plate at a rate of about an inch every 2.5 years (a centimeter a year).

"Distill the essence of coastal Alaska into one place—wild, dynamic, and scenic, rich with the signatures of glaciers, light with the marks of people, unforgiving in stormy seas, unforgettable in warm sunshine—and you have Kenai Fjords, the smallest national park in Alaska. Here the south-central part of the state tumbles into the Gulf of Alaska; here the land challenges the sea with talonlike peninsulas and rocky headlands, while the sea itself reaches inland with long fjords and hundreds of quiet bays and coves. The Harding Icefield is the park's crown jewel, almost 700 square miles (1,813 square kilometers) of ice up to a mile (1.6 kilometers) thick. It feeds nearly three dozen glaciers flowing out of the mountains, six of them to tidewater. The Harding Icefield is a vestige of the massive ice sheet that covered much of Alaska in the Pleistocene era." - Jenny from Bookmarklet

"Bryce Canyon National Park ( /ˈbraɪs/) is a national park located in southwestern Utah in the United States. The major feature of the park is Bryce Canyon which, despite its name, is not a canyon but a giant natural amphitheater created by erosion along the eastern side of the Paunsaugunt Plateau. Bryce is distinctive due to geological structures called hoodoos, formed by wind, water, and ice erosion of the river and lake bed sedimentary rocks. The red, orange, and white colors of the rocks provide spectacular views for park visitors. Bryce sits at a much higher elevation than nearby Zion National Park.

"The first episode illustrates a 'journey' around the globe and reveals the effect of gradual climatic change and seasonal transitions en route. During Antarctica's winter, emperor penguins endure four months of darkness, with no food, in temperatures of −70 °C (−94 °F). Meanwhile, as spring arrives in the Arctic, polar bear cubs take their first steps into a world of rapidly thawing ice. In northern Canada, the longest overland migration of any animal — over 3,200 kilometres (2,000 mi) — is that of three million caribou, which are hunted by wolves, and one such pursuit is shown. The forests of eastern Russia are home to the Amur leopard; with a population of just 40 individuals in the wild, it is now the world's rarest cat.

"A rare natural phenomenon turns one of Austria’s most beautiful hiking trails into a 10 meter-deep lake, for half the year. Located at the foot of the Hochschwab Mountains, in Tragoess, Styria, Green Lake is one of the most bizarre natural phenomena in the world. During the cold winter months, this place is almost completely dry, and used as a country park where hikers love to come and spend some time away from urban chaos. But as soon as temperatures rise, the snow and ice covering the mountaintops begin to melt, and the water pours down, filling the basin below with crystal-clear water. Water levels go from one-two meters at most, to over 10 meters, in the early summer. The waters of Green Lake are highest in June, when this extraordinary place is invaded by divers, curious to see what a mountain park looks like underwater. Fish swimming over wooden benches, a grass-covered bottom, trees, roads, roads and even bridges create a surreal setting that feels like it belongs on dry ground. That’s because for half of the year, that’s exactly where it’s at." - Eivind

Sea snail turns its entire shell into a glowing lamp | Not Exactly Rocket Science | Discover Magazine
"It would seem a bit foolish to put a big cap on the end of a torch, right in the path of the beam of light. But that’s exactly what one type of sea snail does. Hinea brasiliana has a pair of organs that give off a bright glow. Many sea animals have this ability but the snail’s living torches are permanently hidden. They sit underneath the hard shell and can’t be pushed outside. And yet, the light not only finds a way through, it also somehow diffuses throughout the shell so that the entire structure starts to glow. Although hundreds of sea creatures can produce their own light (bioluminescence), H.brasiliana is one of the few snails to have this ability. Under natural light, its shell is a yellowy brown colour but once it turns on its living lights, it becomes suffused with soft pulses of blue-green light. The glow comes from patches of cells near the snail’s mucus glands, which sit behind the front opening of the shell. To Dimitri Deheyn, who discovered the snail’s ability, it’s “like a slow strobe on an erratic pacemaker or battery”." - Eivind from Bookmarklet
"Indonesia's Lombok island sits just across a narrow strait from Bali. But unlike its sister island -- a travel Mecca that has become even more popular thanks to Russian and Chinese package tours -- Lombok has remained largely in the shadows, save for a trickle of foreign travelers who have discovered its charms. Now the bucolic island is gaining a following among tourists turned off by the commercialization of Bali. A number of posh boutique resorts have recently sprung up along Lombok's western coast to cater to this crowd. They serve capiroscas and other fancy cocktails on the beach at sundown, but are just a stone's throw away from rural, unspoiled countryside, much as Bali was four decades ago." - Eivind from Bookmarklet
