2008

Cheerio! [Jul 2008 - materials]
Anyone who enjoys a delicious bowl of mixed grain Cheerios in the morning, rather than being force-fed lumpy porridge, will know all about the "Cheerios Effect". This phenomenon is usually manifest at a particular point during breakfast when just a few torus-shaped ...

Winging it [Jul 2008 - astronomy]
You might expect that astronomers would know all there is to know about the composition of our nearby planetary neighbours, but apparently not. By measuring the charged particles in the planet Mercury's ...

Inconvenient ice sheets [Jul 2008 - earth]
The present environmental crisis over climate change hinges on the validity of global temperature measurements, observations of local conditions, such as changes in the ice caps, ...

 

Turning up the heat on quantum mechanics [Jun 2008 - physics]
Scientists have made a startling prediction about the quantum world that seems to show that simply "taking the temperature" of certain types ...

Pathological proteins produce polymers [Jun 2008 - chemistry]
Deposits of distorted or otherwise errant proteins are key to understanding various brain diseases including Alzheimer's, Parkinson's, and the prion disease variant-CJD, they are also implicated in the pathology of type II diabetes. However, while such "amyloids" are a medical nightmare, researchers ...

Size matters on a planetary scale [Jun 2008 - astronomy]
Steering well clear of Mars and Phoenix, the Intute Spotlight this month falls on the smallest planet yet discovered beyond our Solar System. An international team of astronomers led by David Bennett of the University of Notre Dame, Indiana, found ...

Flush with nanoparticles [May 2008 - chemistry,earth]
What happens to carbon-based nanoparticles when they enter groundwater? Can municipal water supplies filter them out? And, if they cannot will they cause health problems? These are crucial questions ...

Ocean oxygen starvation [May 2008 - earth,physics]
Oxygen-poor regions of tropical oceans are expanding as the oceans warm, limiting the areas in which predatory fishes and other marine organisms can live or enter in search of food, ...

Carbon spheres to the dinosaurs [May 2008 - earth]
Palaeontologists presume that an asteroid impact led to such enormous and widespread environmental upheaval that it wiped out the dinosaurs and thousands of other species when it struck the Earth.

Good-looking models [Apr 2008 - earth]
Climate change sceptics often cite the fact that predictions about global warming, droughts, increased hurricane activity and other harbingers of doom are based not on experimental science but merely ...

Filling up with hydrogen [Apr 2008 - chemistry]
Using renewable energy sources, such as wind, solar, and tidal, to convert biomass into hydrogen fuel, could underpin a future "hydrogen economy" based on fuel cell devices that then convert the hydrogen into water and release the pent up energy. However, ...

Black hole revelation [Apr 2008 - astronomy]
You wait for one for ages and then three come along all at once. First, the smallest black hole ever seen with a mass just 3.8 times that of our Sun and a diameter of about 20 km has been observed in the Milky Way Galaxy binary system XTE J1650-500 in the southern ...

Timeless puzzle solved [Mar 2008 - earth]
Canadian and UK geologists have revealed one of the inner secrets of rocks half a billion years old that harbour one of the most important fossil beds ...

Life's meteoric insights [Mar 2008 - chemistry]
Life is handed. Science has known that ever since the time of Louis Pasteur tweezing apart crystals of naturally produced tartaric acid into left-handed and right-handed forms. ...

Want optical chips with that? [Mar 2008 - materials]
Ever-smaller and ever-faster microelectronics devices with increased storage space, more communications and other functions, and much-reduced battery usage, are part of the incentive behind research into photonic crystals. ...

Nanoscopic gas cylinders [Feb 2008 - earth, materials]
New materials that act like nanoscopic gas cylinders complete with temperature-controlled gas taps have been developed by researchers in Canada. The materials hold the promise ...

Glassy water [Feb 2008 - physics, chemistry]
Water is an odd material. It can dissolve many different types of compounds far beyond the range of other molecular solvents. It expands when it freezes, retains much more heat than one might expect, has a much higher surface tension than it should, and exists in all three states, ...

The bitter-sweet chemistry of quinine [Feb 2008 - chemistry, pharma]
Bitter nitrogen-containing compounds found in the bark of the cinchona tree, native to South America, include the well-known antimalarial compound quinine. Quinine has been used as an additive for tonic water and is the compound that gives this drink its fluorescence.

The sparks of erosion [Jan 2008 - chemistry,earth,physics]
Improved climate models could result from a better understanding of how erosion occurs as US researchers discover that electricity as well as wind is involved ...

Less than green biofuels [Jan 2008 - earth]
Fuels derived from renewable resources, such as biomass and specifically cultivated fuel crops are currently being touted as a useful supplement and ultimate replacement for fossil fuels. The underlying principle in addition to their sustainability ...

Galactic mashup and the blue blobs [Jan 2008 - astronomy]
Astronomical news almost invariably focuses on unusually shaped objects, pretty nebulae that resemble earthly creatures, spitting jets from supernovae. However, odd blue blobs that mark the crash site of a galactic ...
