A dark winter for UK physics

... by Sarah

Despite widespread financial gloom, 2009 has been an excellent vintage for physics and astronomy. The Hubble Space Telescope's final servicing mission was declared a resounding success, LHC finally powered up after last year's false start, several new astronomy satellites were launched and astronomers have tantalisingly reported a possible first-ever...

Brain implants show what attention looks like

Imagine you're playing a game of basketball--running down the length of the court, your shoes squeaking and you're fingers bouncing the ball about every 2 strides. You're darting left and right, about to sneak under the goal, leap over defenders, and slam it in for 2 points.

The fans cheer in a wave of pure elation. (Admittedly, a creative imagination.)

New Ultra hard diamond found in meteorite

Researchers at the Université de Lyon in France, have discovered what appears to be an unexpected new form of ultrahard diamond and a new ultrahard form that was previously predicted, both harder then commonly found diamond. These forms were found in the Havero meteorite, which fell to earth in Finland in 1971. The meteorite was split up and spread around research facilities around the world, with the Université de Lyon conducting research on the 30µm thick, 4mm by 4mm square piece of meteorite they were given.

Protein...evolution...

If you ignore for a second the constant forward-looking attention Internet news demands and stretch your mind back to the Mad Cow Disease scare of 2004, you might remember thinking "how strange that proteins can act as pathogens in the mammalian body!"

Mad Cow scares us because it's an enigma--a protein disease that acts like it has DNA. But now it's looking more familiar, as researchers prove it mutates very much like a DNA or RNA virus or bacteria.

Germany's Highest Court Rules On LHC: "Put Up, Or Shut Up!"

In February, Germany's Highest Court, the Bundesverfassungsgericht ruled on the motion of a German residing in the Swiss city of Zurich, to pressure the German government into trying to stop the operation of the Large Hadron Collider, the biggest machine ever built, and that also has an easy to misspell name.

Thought ATP was just an energy molecule? Think again.

ATP's new role in human health and disease...

As a undergraduate student, every microbiology/biochem professor i ever had relentlessly drilled into our heads: ATP=energy. Written in my notes on the side margin (and going round and round through my head as i crammed for tests ignored until the last minute) was: ATP=energy, ATP=energy, ATP=energy.

It's true, cells all over our body use Adenosine triphosphate for energy by ripping off one of the phosphate groups somehow (kinda had to reach back to remember that fact.) But, after decades of research into ATP receptor molecules, it seems there is a new way to look at our old familiar adenosine.

The Randomness of Translations - A Good Book, Spoiled

God does not play dice with the universe; He plays an ineffable game of His own devising which might be compared, from the perspective of any of the other players (i.e. everybody), to being involved in an obscure and complex version of poker in a pitch-dark room, with blank cards, for infinite stakes, with a Dealer who won't tell you the rules, and who smiles all the time.

Mediterranean sea filled quickly in a gargantuan flood?

It took me a many years (and many hours with a John McPhee book in my lap) to realize how slow things happen in geologic time. Ranges like the Rocky Mountains jut upward over millions of years, and bodies of water like Lake Superior fill rifts in techtonic plates over thousands of years.

The slower-than-glacial pace of the earth's changes is why I was surprised to hear recently that the Mediteranean sea filled up in a mere two years!

A dark winter for UK physics

The sun sets on the UK's involvement in Gemini
Despite widespread financial gloom, 2009 has been an excellent vintage for physics and astronomy. The Hubble Space Telescope's final servicing mission was declared a resounding success, LHC finally powered up after last year's false start, several new astronomy satellites were launched and astronomers have tantalisingly reported a possible first-ever detection of dark matter particles. But in the UK, the year was closed on a blue note following an ominous pre-budget report in early December and the subsequent announcement of drastic cuts to the particle physics and astronomy programmes by the country's Science and Technology Facilities Council, STFC.

Alistair Darling's pre-budget report released on 9 December projecting £600 million of savings from higher education by 2012 showed a glimpse of things to come. In the following week, in which Herschel astronomers showcased their first results in Madrid and the CDMS scientists reported their dark matter research results, British scientists received a cold shower when STFC announced wide-reaching cuts to its entire programme, to fill a hole of around £40 million.

How to Put the Moon on Your Blog

A number of people have asked me about the little moon widget you can see at the foot of this blog, which shows the phases of the moon in real-time. In fact, the image is generated by the U.S. Navy's Time Service Department.

These lunar phase images were created by R. Schmidt from ray-traced images of the Moon. A Clementine spacecraft mosaic of the lunar surface was mapped onto a sphere, and scenes were rendered as a virtual Sun "orbited" the Moon. The depiction of lunar surface features suffers geometric distortion but the terminator is correct with respect to the spherical Moon.
