New method for watching proteins fold (December 23, 2011) -- A protein's function depends on both the chains of molecules it is made of and the way those chains are folded. And while figuring out the former is relatively easy, the latter represents a huge challenge with serious implications because many diseases are the result of misfolded proteins. Now, a team of chemists has devised a way to watch proteins fold in "real-time," which could lead to a better understanding of protein folding and misfolding in general. ... > full story

Chinese fossils shed light on evolutionary origin of animals from single-cell ancestors (December 23, 2011) -- Evidence of the single-celled ancestors of animals, dating from the interval in the Earth's history just before multicellular animals appeared, has been discovered in 570 million-year-old rocks from South China. ... > full story

Possible cure for leukemia found in fish oil (December 23, 2011) -- A compound produced from fish oil that appears to target leukemia stem cells could lead to a cure for the disease, according to researchers. ... > full story

Built-in 'self-destruct timer' causes ultimate death of messenger RNA in cells (December 22, 2011) -- Researchers have discovered the first known mechanism by which cells control the survival of messenger RNA (mRNA) -- arguably biology's most important molecule. The findings pertain to mRNAs that help regulate cell division and could therefore have implications for reversing cancer's out-of-control cell division. ... > full story

Long intervening non-coding RNAs play pivotal roles in brain development (December 22, 2011) -- Scientists have identified conserved, long intervening non-coding RNAs that play key roles during brain development in zebrafish, and went on to show that the human versions of these RNAs can substitute for the zebrafish lincRNAs. Until now, lincRNAs have been studied primarily in cell lines rather than at the organismal level, which has precluded research into how lincRNAs affect growth and development. ... > full story

Reclaiming land after a forest fire (December 22, 2011) -- Researchers treated burnt soil with an organic polymer used in agriculture. Applying granules of the non-toxic polymer cut soil erosion by half in both laboratory and field experiments. ... > full story

Starlings help explain irrational preferences (December 22, 2011) -- Research into decision-making by European starlings may help explain why many animals, including humans, sometimes exhibit irrational preferences. ... > full story

First ever direct measurement of Earth's rotation (December 22, 2011) -- Scientists have just plotted changes in Earth's axis through laboratory measurements. To do this, they constructed the world's most stable ring laser. Previously, scientists were only able to track shifts in the axis indirectly by monitoring fixed objects in space. Capturing these shifts is crucial for navigation systems. ... > full story

High genetic diversity in an ancient Hawaiian clone (December 22, 2011) -- The entire Hawaiian population of the peat moss Sphagnum palustre appears to be a clone that has been in existence for some 50,000 years, researchers have discovered. ... > full story

Jaguar photo shows conservation success in Bolivia (December 22, 2011) -- A dramatic photo of a female jaguar and her two cubs near the Isoso Station of the Santa Cruz-Puerto Suarez Gas Pipeline in Kaa Iya National Park in Bolivia has just been released. The adult jaguar, nicknamed Kaaiyana, has been seen with her cubs in the area for over a month; though conservationists have confirmed she has been a resident in the vicinity for at least six years. ... > full story

'Alien' eggs benefit mockingbirds (December 22, 2011) -- Mockingbirds rarely remove the 'alien' eggs parasitic cowbirds lay in their nests because keeping them dilutes the risk of their own eggs being attacked. ... > full story

Promising results in mice on needle-free candidate universal vaccine against various flu viruses (December 22, 2011) -- Scientists have discovered that an antigen common to most influenza viruses, and commonly referred to as matrix protein 2, when administered under the tongue could protect mice against experimental infection caused by various influenza viruses, including the highly pathogenic avian H5 virus and the pandemic H1 virus. ... > full story
