Songs in the key of sea Posted: 28 Sep 2012 09:53 AM PDT Scientists have used special algorithms to create musical patterns from data collected from microbes in the western English Channel.

Venice Lagoon research indicates rapid climate change in coastal regions Posted: 28 Sep 2012 09:53 AM PDT New research has revealed that the sea surface temperature in coastal regions is rising as much as ten times faster than the global average of 0.13 degrees per decade.

Exposure to herbicide may increase risk of rare disorder Posted: 28 Sep 2012 09:52 AM PDT A common herbicide used in the United States may be linked to an increased risk of a congenital abnormality of the nasal cavity known as choanal atresia, say researchers.

Bioengineers introduce 'Bi-Fi' -- The biological 'Internet' Posted: 28 Sep 2012 07:38 AM PDT Bioengineers have created a biological mechanism to send genetic messages from cell to cell -- something they've nicknamed the biological Internet, or "Bi-Fi."

Predatory bacterial crowdsourcing: Scientists ID simple formula that allows bacteria to engulf food in waves Posted: 28 Sep 2012 06:37 AM PDT Scientists have discovered the mechanism that allows one of the world's smallest predators -- the soil bacteria Myxococcus xanthus -- to form collective waves that spread and engulf bacterial prey. The study finds that the same mechanism helps M. xanthus spread quickly and stay atop prey until it is devoured.

Ancient stinging nettles reveal Bronze Age trade connections Posted: 28 Sep 2012 06:37 AM PDT A piece of nettle cloth retrieved from Denmark's richest known Bronze Age burial mound Lusehøj may actually derive from Austria, new findings suggest. The cloth thus tells a surprising story about long-distance Bronze Age trade connections around 800 BC.

Local funding supports open access sequencing of the Puerto Rican parrot genome Posted: 28 Sep 2012 05:53 AM PDT The critically endangered Puerto Rican parrot (Amazona vittata) is the only surviving parrot species native to the United States. A genomic sequencing project, funded by community donations, has just been completed, the first sequence of A. vittata, the first of the large Neotropical Amazona birds to be studied at the genomic level.

Loop the loop, DNA style: One- or two-way transcription depends on gene loops Posted: 28 Sep 2012 05:52 AM PDT Scientists have discovered that, by forming or undoing gene loops, cells manipulate the path of the transcription machinery – which reads out instructions from DNA – controlling whether it moves along the genetic material in one direction or two.

Fall calls bats to hibernate, scientists to study them Posted: 28 Sep 2012 05:49 AM PDT Bats are an important weapon in the battle against insect pests, but a deadly fungal disease is killing more and more of them. They flock to mines and caves in the fall, where scientists study them while they hibernate. New research helps track their origins, which could lead to better prevention and control of White Nose Syndrome.
