The moon will take the smallest of dips through the Earth's shadow in a minor eclipse tonight (May 24) and you can watch the lunar event live online via a webcast. The lackluster lunar eclipse will star in a free webcast by the Slooh Space Camera, which offers live views of the night sky via remotely operated telescopes. The eclipse webcast will begin at 11:37 p.m. EDT (0337 May 25 GMT).

The event comes on the heels of a "ring of fire" solar eclipse on May 10 and another partial lunar eclipse on April 25. Stargazing experts predict that tonight's eclipse won't be anywhere near as impressive as the other recent eclipses because only a tiny sliver of the May full moon will pass through the penumbra, the outermost part of Earth's shadow.

"It will thus be impossible to notice anything out of the ordinary concerning the moon's overall appearance," SPACE.com's skywatching columnist Joe Rao explained in a viewing guide today. "It will, in fact look like any other full moon."

Technologies are tools for doing or making things. They are a means to transform what nature has given into food, clothing, shelter, means of mobility, means of communication. Technology is a means to an end; it is not an end in itself. But when we stop perceiving technology as a means mediating between nature and human needs and elevate it to an end in itself, we falsely give it the status of a religion.

The Green Revolution bred seeds to respond to chemical fertilisers - they were called "miracle seeds". The father of the Green Revolution, Norman Borlaug, called the 12 people he sent across the world to spread chemicals by introducing new seeds his "wheat apostles". This is the discourse of religion, not of science and technology.

When the Green Revolution was introduced in India in 1965-66, no assessment was made of the impact chemical fertiliser will have on soil organisms, soil structure and the soil's water-holding capacity. No attempt was made to compare the yields of Green Revolution varieties and the outputs of indigenous varieties and mixed farming system. When we started to conserve native seeds through the Navdanya movement in 1987, we found many of the indigenous varieties outperformed the Green Revolution varieties in grain yield. They also outperformed them in total biomass yield - this really matters because while the grain is eaten by humans, straw is food for soil organisms and farm animals. Our work on mixtures and biodiverse systems of farming shows that as a system, indigenous biodiversity produces more food and nutrition per acre.

GPs can now refer patients with a common iron overload disorder for prompt treatment using an app that could see the end of paper based referrals.

In a world first, doctors developed a simple web based app that quickly identifies patients with hereditary haemochromatosis (HH) and refers them directly to the Red Cross blood service for therapeutic blood donation.

Under the old paper based system, patients often have to wait up to three months for paperwork to be completed, delaying much needed treatment and potentially putting them at risk of organ damage.

Twelve years of supersized earthquakes have contaminated GPS sites around the world, a new study finds.

The Global Positioning System is a network of satellites and ground stations that provide location information anywhere on Earth. Except for spots in Australia, western Europe and the eastern tip of Canada, every GPS site on the ground underwent small but important shifts since 2000 because of big earthquakes, according to a study published May 6 in the Journal of Geophysical Research: Solid Earth.

The research confirms that great earthquakes, those bigger than magnitude 8.0, can have far-reaching effects on the Earth's crust. And because GPS is critical for everything from calculating satellite orbits to sea level rise to earthquake hazards, scientists can't ignore these tiny zigs and zags, the researchers conclude.

"We have to find a way to deal with it," said Paul Tregoning, lead study author and a geophysicist at Australia National University in Canberra. "The community needs to work out how to find all the offsets, estimate them accurately and get everyone to agree on how to correct them," he told LiveScience.

Tregoning and his colleagues modeled the sudden jolts in Earth's crust from each of the 15 biggest earthquakes since 2000. They discovered that crust thousands of miles away from the faults had moved horizontally by as much as a tenth of an inch (a few millimeters). The model was checked against a few spots around the planet. On average, the earthquakes deformed the crust by a hundredth of an inch every year (0.4 millimeters a year) - about the width of the lead in a mechanical pencil.

"It's quite amazing to us that we can see this and detect this," Tregoning said.

These tiny effects won't make a difference to the GPS in cars or phones, or the tough little units carried by hikers and mountaineers. But scientists who need precise measurements to calculate sea level rise or satellite orbits should be concerned, Tregoning said.

In September, the U.S. government will fire into orbit a two-stage rocket from a Virginia launchpad. Officially, the mission is a scientific one, designed to improve America's ability to send small satellites into space quickly and cheaply. But the launch will also have a second purpose: to help the elite forces of U.S. Special Operations Command hunt down people considered to be dangerous to the United States and its interests.

For years, special operators have used tiny "tags" to clandestinely mark their prey - and satellites to relay information from those beacons. But there are areas of the world where the satellite coverage is thin, and there aren't enough cell towers to provide an alternative. That's why SOCOM is putting eight miniature communications satellites, each about the size of a water jug, on top of the Minotaur rocket that's getting ready to launch from Wallops Island, Virginia. They'll sit more than 300 miles above the earth and provide a new way for the beacons to call back to their masters.

A solar radiation storm is in progress on May 22nd following an M5-class explosion on the sun's western limb. The source of the flare, which peaked at 1332 UT, was departing sunspot AR1745. SOHO coronagraphs observed a magnificent CME emerging from the blast site.

Play the movie again. The speckles dancing across the image are caused by high-energy solar protons striking the CCD camera in SOHO's coronagraph. Those protons were guided toward Earth by magnetic field lines that connect our planet to the blast site. The rain of protons is what forecasters mean by a "radiation storm." This storm ranks S2 on NOAA storm scales.

A new rifle goes on sale on Wednesday, and it's not like any other. It uses lasers and computers to make shooters very accurate. A startup gun company in Texas developed the rifle, which is so effective that some in the shooting community say it should not be sold to the public.

It's called the TrackingPoint rifle. On a firing range just outside Austin in the city of Liberty Hill, a novice shooter holds one and takes aim at a target 500 yards away. Normally it takes years of practice to hit something at that distance. But this shooter nails it on the first try.

The rifle's scope features a sophisticated . The shooter locks a laser on the target by pushing a small button by the trigger. It's like a video game. But here's where it's different: You pull the trigger but the gun decides when to shoot. It fires only when the weapon has been pointed in exactly the right place, taking into account dozens of variables, including wind, shake and distance to the target.

Now they're just messing with us. Physicists have long known that quantum mechanics allows for a subtle connection between quantum particles called entanglement, in which measuring one particle can instantly set the otherwise uncertain condition, or "state," of another particle -- even if it's light years away. Now, experimenters in Israel have shown that they can entangle two photons that don't even exist at the same time.

"It's really cool," says Jeremy O'Brien, an experimenter at the University of Bristol in the United Kingdom, who was not involved in the work.

Such time-separated entanglement is predicted by standard quantum theory, O'Brien says, "but it's certainly not widely appreciated, and I don't know if it's been clearly articulated before."

Entanglement is a kind of order that lurks within the uncertainty of quantum theory. Suppose you have a quantum particle of light, or photon. It can be polarized so that it wriggles either vertically or horizontally.

The quantum realm is also hazed over with unavoidable uncertainty, and thanks to such quantum uncertainty, a photon can also be polarized vertically and horizontally at the same time. If you then measure the photon, however, you will find it either horizontally polarized or vertically polarized, as the two-ways-at-once state randomly "collapses" one way or the other.

Entanglement can come in if you have two photons. Each can be put into the uncertain vertical-and-horizontal state. However, the photons can be entangled so that their polarizations are correlated even while they remain undetermined. For example, if you measure the first photon and find it horizontally polarized, you'll know that the other photon has instantaneously collapsed into the vertical state and vice versa -- no matter how far away it is. Because the collapse happens instantly, Albert Einstein dubbed the effect "spooky action at a distance." It doesn't violate relativity, though: It's impossible to control the outcome of the measurement of the first photon, so the quantum link can't be used to send a message faster than light.

While comets can't tell lies, they do sometimes grow long noses. As the weeks click by and our perspective on Comet L4 PANSTARRS changes, its original plume-like dust tail has shrunk and faded while a second tail just won't stop growing. I'm talking about the anti-tail, so called because it points toward the sun instead of away. Like the normal dust tail, an anti-tail is formed from fresh dust blown back from the comet's head by the pressure of sunlight. As the comet continues along its orbital path, last week's dust lingers behind, forming a "trail of breadcrumbs" in its wake. Right now those breadcrumbs look like a light saber straight out of Star Wars. Time exposure photographs show a striking sunward-pointing appendage more than 6 degrees (12 full moons) long. I've been keeping an eye on Comet PANSTARRS here at home and can report that the anti-tail is plainly visible with a telescope under dark skies. Watching it grow from a short nub to the most dominant feature of this remarkable object has been the highlight of many a clear night.

Australian scientists have charted the path of insulin action in cells in precise detail like never before. This provides a comprehensive blueprint for understanding what goes wrong in diabetes.

The breakthrough study, conducted by Sean Humphrey and Professor David James from Sydney's Garvan Institute of Medical Research, is now published in the early online edition of the journal Cell Metabolism.

First discovered in 1921, the insulin hormone plays a very important role in the body because it helps us lower blood sugar after a meal, by enabling the movement of sugar from the blood into cells.

Until now, although scientists have understood the purpose of insulin at a broad level, they have struggled to understand exactly how it achieves its task.

The latest analytical devices called mass spectrometers now provide the tool that has been missing -- the means of looking into the vastly complex molecular maze that exists in every single cell in the human body.

These powerful devices have opened up a field known as 'proteomics', the study of proteins on a very large scale. Proteins represent the working parts of cells, using energy to perform all essential functions such as muscle contraction, heartbeat or even memory.
