7 Lesser Known Wonders Of The World

Photo: Jean-Marie Hullot

From Environmental Graffiti:

We all know that there are sights on earth regarded as the Wonders of the World – whether ancient or modern – sights such as the Great Pyramids of Giza, the Taj Mahal, or the Grand Canyon in Colorado with its awesome grandeur. These are not, however, necessarily the sights you have to see, because the word 'wonder' can apply to so many other locations around the globe. Here are a selection of stunning places to see, if you ever get the chance.

The New Twitter Isn't Nearly New Enough



From Daily Finance:


As a Twitter user, I was interested in seeing just how different Twitter.com's new incarnation actually is, especially because it's been billed as the most significant product release for the micro-messaging service in a long time.

Would it finally give me a reason to ditch my Twitter client and go back to Twitter.com? Would it finally produce a revenue model commensurate with the company's stiff venture capital valuation and immense promise? Would it leap tall buildings in a single bound? Alas, none of the above. The new Twitter is fairly tame -- and fairly indicative of the troubles that have beset the popular but not easily monetizable company.

From Physorg.com:

(PhysOrg.com) -- Sunspot formation is triggered by a magnetic field, which scientists say is steadily declining. They predict that by 2016 there may be no remaining sunspots, and the sun may stay spotless for several decades. The last time the sunspots disappeared altogether was in the 17th and 18th century, and coincided with a lengthy cool period on the planet known as the Little Ice Age.

US Assessment Of Terrorist Threats Poor, Says Panel


From New Scientist:

Only "low confidence" should be placed in most of the risk analyses of terrorist threats conducted by the US Department of Homeland Security, concludes a review by a National Research Council panel.

Created after the 9/11 attacks to cover national perils ranging from terrorism to natural disasters, the DHS got off to a rough start. Critics blasted its lack of attention to natural disasters after its bungled response to hurricane Katrina.

Yet the panel finds that DHS models for natural disaster risks are "near the state of the art" and well suited to assess the effects of earthquakes, floods and hurricanes.

Why Some Quakes Cause Killer Tsunamis


From Futurity:

U. SOUTHAMPTON (UK)—Researchers have uncovered clues as to why some undersea earthquakes generate huge tsunamis. Their findings, published recently in the journal Science, may help explain why the 2004 Sumatra “Boxing Day Tsunami” was so devastating.

Early in the morning of December 26, 2004, a powerful undersea earthquake started close to Simeulue Island off the west coast of Sumatra, Indonesia, and extended more than 1,200 kilometers to the north.

How Mass Migration Might Have Evolved


From Wired Science:

Just a few small changes in the social behaviors of even solitary animals may set in motion an evolutionary cascade ending in massive, globe-spanning migrations, suggests a study of migration’s origins.

Such migrations — caribou across the Arctic and wildebeest across the Serengeti, birds and butterflies over oceans — are among nature’s most beautiful and mystifying phenomena. Many models suggest how migration works now, in terms of individual actions producing collective behavior; but how it could have started in the first place is far harder to explain.

Progress of waves through open sea sends vibrations that magnify with height up the entire atmospheric column.

The signals of GPS satellites could be used to monitor tsunamis as they sweep across the ocean. In the most detailed study to date of the effect, scientists have shown that even though open ocean tsunami waves are only a few centimetres high, they are powerful enough to create atmospheric vibrations extending all the way to the ionosphere, 300 kilometres up in the atmosphere.

Glacial Armour Lets Mountains Rise High

Ripe for the buzz saw (Image: Egner Photography/iStock)

From New Scientist:

Glaciers limit mountain height by stripping rock off the top – but not always. If conditions are right, glacial ice will protect the rocks beneath to let mountains grow.

The upper reaches of high mountains are covered with snow all year round, allowing glaciers to form. As these rivers of ice move slowly downhill, they wear away the rocks beneath them, meaning that mountains should not grow much beyond the height of their snowline: any rock that is pushed up above this altitude will eventually get worn away by the ice. This is called the buzz-saw hypothesis, because, like superhuman circular saws, the glaciers effectively cut the heads off mountains above a certain height.

Only Two Men Have Reached The Deepest Part Of The Sea

Explorers Jacques Picard and Don Walsh reached the very deepest point of the ocean on January 23, 1960

As Director James Cameron Plans To Film Avatar Sequel Seven Miles Below The Sea's Surface, We Go Into The Deadly Deep With The Only Two Men Who've Been There -- The Daily Mail

Five thousand fathoms under the waves, a deafening clang rang out through the cramped, freezing submarine, causing the whole ­vessel to shake like a leaf.

Squinting through their tiny Plexiglas window into the abyss, the two explorers’ hearts missed
a beat.

‘It was a pretty hairy experience,’ they said afterwards with some understatement. The outer
layer of their porthole had cracked under the ­unimaginable weight of six miles of seawater — and they still had more than a mile to descend.

From Discovery News:

At 17 feet, the bird's wingspan may exceed that of any other flying animal ever to exist. Size, however, has its drawbacks.

Soaring the Chilean skies 5-10 million years ago, an enormous bony-toothed bird has set the world wingspan record. The bird's wingspan was at least 17 feet, according to scientists.

The measurement is based on well preserved wing bones from the newly named bird species, Pelagornis chilensis, a.k.a. "huge pseudoteeth" from Chile. The animal weighed about 64 pounds and belonged to a group known as pelagornithids -- birds characterized by long, slender beaks bearing many spiny, tooth-like projections.

Top 10 Animal Recruits in War


From Live Science:

Humans have enlisted animals to help fight their battles since the dawn of war, and today's militaries use an even wider range of creatures for everything from bomb sniffing to coastline patrolling.

That may seem remarkable, considering that dogs, horses and other animals certainly did not evolve for the purpose of human conflict. Yet nature's designs have not only stood the test of time, but have also inspired human engineers to try to harness their power directly or through mechanical imitations.

Here we count down some of the creatures that have become unwitting recruits in both ancient and modern warfare.

Women generally find calm, collected men more attractive, and scientists now suggest they know the biology of why that is.

Investigations into what makes men desirable often focus on testosterone. The hormone is linked with masculine facial traits, such as larger jaws and heavier brows, and is typically associated with better long-term health. As such, it might at first glance make sense from an evolutionary point of view if women found testosterone-laden men especially attractive.

The cost of keeping tigers alive in the wild is about $80m (£50m) per year, say conservationists - but only about $50m (£30m) per year is being pledged.

The figures come from a new assessment that suggests targeting efforts in 42 selected breeding sites.

Building tiger populations in these sites would enable other areas to be re-populated later, the researchers report in the journal PLoS Biology.

About 3,500 tigers remain in the wild, and only about 1,000 breeding females.
