Decoding the genome of Chlorella microalgae, a promising genus for biofuel production

The analysis of the complete genome of Chlorella microalgae, a promising genus for biofuel production, has now been completed. The detailed elucidation of the Chlorella genome, also widely used as a food supplement, will make it possible to rationalize its industrial use. This analysis has also brought to light unexpected findings at the fundamental level: it suggests that Chlorella could have a...

Today's mystery bird for you to identify

'Prima donna' protein doesn't work well in pairs

A new study by Rice University bioengineers finds that the workhorse proteins that move cargo inside living cells behave like prima donnas. The protein, called kinesin, is a two-legged molecular machine. Rice's scientists invented tools that could measure the pulling power of kinesin both singly and in pairs, and they report this week in Biophysical Journal that kinesins don't work well together...

A safety switch prevents a big bang

German scientists developed a new method to prevent explosions due to electrical sparks. For this development and the successful technology transfer, they received this year's Technology Transfer Prize of the Chamber of Industry and Commerce, Braunschweig.

Coastal dolphins quieter than thought

Dolphins are thought to be able to communicate with each other over vast expanses of ocean, between distances as far as 15 miles apart. Studies of dolphin whistles have suggested that they should carry that far in water, which transmits sound much better than air does.

Consumer Reports: Kinect not 'racist'

(AP) -- Looking to debunk a report that Microsoft's new motion-sensing video game controller might be racist, Consumer Reports says it found no evidence that Kinect has problems recognizing users with darker skin.

Engineers assessing Cassini spacecraft

Engineers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., are working to understand what caused NASA's Cassini spacecraft to put itself into "safe mode," a precautionary standby mode. Cassini entered safe mode around 4 p.m. PDT (7 p.m. EDT) on Tuesday, Nov. 2.

Looking older than your age may not be a sign of poor health: study

Even though most adults want to avoid looking older than their actual age, research led by St. Michael's Hospital shows that looking older does not necessarily point to poor health. The study found that a person needed to look at least 10 years older than their actual age before assumptions about their health could be made.

New strategy to eliminate malaria

UCSF global health experts have outlined a new strategy and action plan to help countries eliminate malaria and bring the world closer to global eradication of the deadly disease.

Not all clones the same

Despite their name, not all clones are created equal. This is especially true for the products of somatic cell nuclear transfer (SCNT), which entails the transplantation of the nucleus from a mature somatic cell, or non-reproductive cell, into an oocyte, or immature female ovum, whose nucleus has been removed. The result is a genomically reprogrammed cell that has been ‘tricked’ into...

Replacing faulty neurons

Researchers from the RIKEN Center for Developmental Biology, Kobe, have shown that neurons called Purkinje cells can not only be generated from embryonic stem (ES) cells, but can also become fully integrated into existing neuronal circuits when transplanted into the brains of mouse fetuses.

Selected hens give new genetic insights

Studies of heavy, fast-growing hens and small, slow-growing hens provide important new knowledge on the origin of the genetic variation that has enabled them to adapt rapidly to new extreme environments. This is shown by new research findings published in the online scientific periodical PLOS Genetics.
