> Dramatic climate change is unpredictable (October 29, 2010) -- The
> fear that global temperature can change very quickly and cause
> dramatic climate changes is great around the world. But what causes
> climate change and is it possible to predict future climate change?
> New research shows that it may be due to an accumulation of
> different chaotic influences and as a result would be difficult to
> predict. ... > full story
> New strategy to kill bugs -- even those in hiding (October 29, 2010)
> -- New strategies to apply antibiotics more effectively to
> hibernating bugs have been developed by researchers in the UK. ... >

> Making better biosensors with electron density waves (October 29,
> 2010) -- An emerging field with the tongue-twisting name of
> "optofluidic plasmonics" promises a new way to detect and analyze
> biological molecules for drug discovery, medical diagnostics, and
> the detection of biochemical weapons. Researchers have succeeded in
> merging a microfluidics system with plasmonics -- sometimes called
> "light on a wire" -- onto a single platform. Plasmonics is based on
> electron waves on a metal surface excited by incoming light
> waves. ... > full story
> North Sea oil recovery using carbon dioxide is possible, but time is
> running out, expert says (October 29, 2010) -- Oil recovery using
> carbon dioxide could lead to a North Sea oil bonanza worth £150
> billion (0 billion) -- but only if the current infrastructure is

> (October 28, 2010) -- Scientists have identified a potential new

> measles, mumps and the flu. ... > full story
> Early sauropod dinosaur: First complete skeleton found (October 28,
> 2010) -- Scientists have discovered in China the first complete
> skeleton of a pivotal ancestor of Earth's largest land animals --
> the sauropod dinosaurs. The new species, tentatively dubbed
> Yizhousaurus sunae, lived on the flood plains around Lufeng in the
> Yunnan Province of South China about 200 million years ago. The

> defies past estimates (October 28, 2010) -- Countless people clung
> to life in the branches of trees hemming the shorelines during the
> deadly 2004 tsunami that killed more than 230,000 coastal residents
> in Indonesia, India, Thailand and Sri Lanka. In the aftermath of the
> disaster, land change scientist Chandra Giri from the US Geological
> Survey decided to explore to what degree those unique trees -- which
> make up valuable forest ecosystems called mangroves -- safeguard
> lives, property and beaches during hurricanes, tsunamis and
> floods. ... > full story
> Predicting smoggiest days: Experiments improve accuracy of ozone
> predictions in air-quality models (October 28, 2010) -- A research
> team has fully characterized a key chemical reaction that affects
> the formation of pollutants in smoggy air in the world's urban
> areas. When applied to Los Angeles, the laboratory results suggest
> that, on the most polluted days and in the most polluted parts of
> L.A., current models are underestimating ozone levels by 5 to 10
> percent. ... > full story
> Scientists 'cage' genetic off switches so they can be activated by
> UV light (October 28, 2010) -- Researchers have found a way to

> Speed gun for Earth's insides to help measure mantle motion (October
> 28, 2010) -- Researchers have developed a seismological "speed gun"
> for the inside of Earth. Using this technique they will be able to
> measure the way the Earth's deep interior slowly moves around. This
> mantle motion is what controls the location of our continents and
> oceans, and where the tectonic plates collide to shake the surface
> we live on. ... > full story
> Archaeological sites threatened by rising seas: Scientists issue
> call to action (October 28, 2010) -- Should global warming cause sea
> levels to rise as predicted in coming decades, thousands of
> archaeological sites in coastal areas around the world will be lost
> to erosion. With no hope of saving all of these sites,
> archaeologists have issued a call to action for scientists to assess
> the sites most at risk. ... > full story
> Into Africa? Fossils suggest earliest anthropoids colonized Africa
> (October 28, 2010) -- A new discovery suggests that anthropoids --
> the primate group including humans, apes and monkeys -- "colonized"
> Africa, rather than evolving in Africa as has been widely accepted.
> What is exceptional about these new fossils is the diversity of
> species: three distinct families that lived in North Africa at
> approximately the same time. This suggests that anthropoids
> underwent diversification, through evolution, previous to the time
> of these new fossils, which date to 39 million years ago. ... > full

> Structural genomics accelerates protein structure determination
> (October 28, 2010) -- Membrane proteins are of immense biological
> and pharmaceutical importance. But so far there are only a handful

> structure of an important ion channel via the analysis of related
> proteins. ... > full story
> New evidence supports 'Snowball Earth' as trigger for early animal
> evolution (October 27, 2010) -- A team of scientists has found new
> evidence linking "Snowball Earth" glacial events to the rise of
> early animals: marine phosphorus. The researchers tracked phosphorus
> concentrations through Earth's history and found a pronounced spike
> in marine phosphorus levels in the mid-Neoproterozoic. They say

> Active ingredient levels vary among red yeast rice supplements
> (October 27, 2010) -- Different formulations of red yeast rice, a

> Variable summer rainfall in U.S. southeast linked to climate change
> (October 27, 2010) -- A doubling of abnormally wet or dry summer
> weather in the southeastern United States in recent decades has come
> from an intensification of the summertime North Atlantic subtropical
> high (NASH), or "Bermuda High." And that intensification appears to
> be coming from global warming, according to a new analysis. ... >

> Small particles show big promise in beating unpleasant odors
> (October 27, 2010) -- Scientists are reporting development of a new
> approach for dealing with offensive household and other odors -- one
> that doesn't simply mask odors like today's room fresheners, but
> eliminates them at the source. Their research found that a deodorant
> made from nanoparticles -- hundreds of times smaller than peach fuzz
> -- eliminates odors up to twice as effectively as today's gold
> standard. ... > full story
> Tale of the headless dragonfly: Ancient struggle, preserved in amber
> (October 27, 2010) -- In a short, violent battle that could have
> happened somewhere this afternoon, the lizard made a fast lunge at
> the dragonfly, bit its head off and turned to run away. Lunch was
> served. But the battle didn't happen today, it happened about 100
> million years ago, probably with dinosaurs strolling nearby. And the
> lizard didn't get away, it was trapped in the same oozing, sticky
> tree sap that also entombed the now-headless dragonfly for
> perpetuity. ... > full story
> Uranium in groundwater? 'Fracking' mobilizes uranium in marcellus
> shale (October 27, 2010) -- Researchers have found that hydraulic

> environmental concerns. ... > full story
> Quakes don't completely shake China's environmental gains, thanks to
> conservation programs (October 27, 2010) -- The impact of China's
