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.

DARPA Makes Uncharacteristic Bid For A Better Means To Declassify Government Docs

President Obama's A.M. Briefing We'd tell you how we got this photograph of the President's morning security run-down, but then we'd have to kill you. (Just kidding. It's public domain.)

From Popular Science:

DARPA is usually so tight-lipped about the technologies it seeks that we can do little but read through bidding solicitations and speculate on what the agency is up to. But in a new request, the DoD’s blue-sky research team is asking for help shining light on the deepest corners of the Pentagon’s archives, asking industry and academia for help in developing technology that will help the government sort through its endless pool of stored information for material suitable for declassification.

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.

Prehistoric Bird Sets Wingspan Record

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.

'Rapid' 2010 Melt For Arctic Ice - But No Record

The Arctic on 3rd September, as visualised using data from Nasa's Aqua satellite.

From The BBC:

Ice floating on the Arctic Ocean melted unusually quickly this year, but did not shrink down to the record minimum area seen in 2007.

That is the preliminary finding of US scientists who say the summer minimum seems to have passed and the ice has entered its winter growth phase.

2010's summer Arctic ice minimum is the third smallest in the satellite era.

Researchers say projections of summer ice disappearing entirely within the next few years increasingly look wrong.

Electron Vortex Could Trap Atoms

Optical vortices, made of twisting beams of light, have been used to spin or move micrometre-sized particles like cells. But electron vortices could potentially trap much smaller particles, says Verbeeck.

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.

The U.S. government doesn't keep an index of broadband internet prices by which to evaluate the success of its broadband promotion policies - the statistics they do have are mushed together with prices for dial-up access - so a couple of researchers at Northwestern University decided to build their own.

What they discovered is that broadband internet prices have remained nearly stagnant since 2004, despite the explosive pace of adoption since then - from approximately 20 percent of U.S. households in 2004 to more than 65 percent today.

'Blade' Of Water That Can Cut Through Steel To Be Used In Afghanistan To Destroy IEDs -- The Daily Mail

A device that shoots a blade of water capable of penetrating steel is to be used in Afghanistan to help soldiers disable improvised explosive devices, or IEDs.

The Stingray was developed by Sandia National Laboratories and 3,000 of the gadgets are heading out to U.S. soldiers in the region this year.

Stingrays are filled with water and an explosive material that - when detonated - creates a shockwave that travels through the water and speeds it up, creating a thin, powerful blade of water capable of penetrating steel.

Why Women Prefer 'Chill' Guys

From Live Science:

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.

Pricetag Set For Tiger Conservation

The Bengal tiger is one of the better protected varieties - but even that is in trouble

From The BBC:

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.

ScienceDaily (Sep. 13, 2010) — A new experiment proposed by physicists at the National Institute of Standards and Technology (NIST) may allow researchers to test the effects of gravity with unprecedented precision at very short distances -- a scale at which exotic new details of gravity's behavior may be detectable.

Why Do Teens Hurt Themselves? The Science Of Self-Injury

From Live Science:

Over the last couple decades, more young people appear to be pulling out razor blades and lighters in order to injure themselves, according to anecdotal reports from counselors. Their intent is not to die, just to inflict harm, a behavior known as non-suicidal self-injury.

A recent study on the mental health of college students, presented in August at the American Psychological Association Meeting, found empirical evidence to document these observations. The results show that at one university, the rate of non-suicidal self-injury doubled from 1997 to 2007.
