Retina created from human embryonic stem cells
Scientists have created an eight-layer, early-stage retina from human embryonic stem cells, the first three-dimensional tissue structure to be made from stem cells.
AE-941, a standardised shark cartilage, does not improve lung cancer survival
The anti-cancer drug AE-941, a shark cartilage derivative, did not improve overall survival in patients with inoperable stage III non-small cell lung cancer, according to a study published online May...
Organic soil solids may aid bacteria
MADISON, Wis., May 26 (UPI) -- U.S. and German scientists say they've determined "mineral-breathing" bacteria found in many oxygen-free environments might be "carbon-breathing" as well.
Climate change: Greater risks than thought
STANFORD, Calif., May 26 (UPI) -- U.S. scientists say they've determined small mammals -- and rest of food chain -- are at a greater risk from global warming than...
What genes help blossoms last longer?
To help cut flowers and potted plants stay fresh longer, a plant physiologist is investigating the gene-controlled mechanisms of plants' aging.
Whales and dolphins - 'resource' or 'right'?
Discoveries of sophisticated intelligence in cetaceans raise new questions about how we relate to them - including whether we should hunt them.
Grin and bear it
Rice University bioengineering students really get their teeth into their senior design projects. This year, one team got everybody else's teeth into it, too...
Scripps Research scientists break barrier to creating potential therapeutic molecules
Scientists from The Scripps Research Institute have created a novel technique that for the first time will allow the efficient production of a molecular structure that is common to a...
Tissue engineering technique yields potential biological substitute for dental implants
A pioneering tissue engineering technique can orchestrate stem cells to migrate to a 3-D scaffold infused with growth factor, holding the translational potential to yield an anatomically correct tooth in...
Video: The 'Lost' Finale Virus
AT&T hikes early termination fees for smartphones, don't lose your way when searching for answers about "Lost," and Facebook CEO Mark Zuckerberg issues a half-apology for privacy gaffes.
Atlas of Gene Activity in Human Brain Launches

New research indicates that DNA sequence itself influences mutation rate
Genetic variation due to DNA mutation is a driving force of adaptation and evolution, as well as a contributing factor to disease. However, the mechanisms governing DNA mutation rate are...
'Stress' protein could halt aging process, say scientists
HSP10 (Heat Shock Protein), helps monitor and organise protein interactions in the body, and responds to environmental stresses, such as exercise and infection, by increasing its production inside cells. Researchers...
Harnessing the power of stem cells to unlock the secrets of motor neuron disease
The Motor Neurone Disease Association is funding its first ever stem cell research programme to help unlock the secrets of this fatal, neurological condition.
Tapping p53 to kill cancer cells more effectively while sparing normal cells
A new finding by researchers in Singapore makes a unique method of cancer treatment now feasible. Their work offers new insight on how to tap on the properties of p53,...
Ultraviolet radiation not culprit killing amphibians, research shows
In nature, ultraviolet radiation from sunlight is not the amphibian killer scientists once suspected. Naturally occurring murky water and females who choose to lay their eggs in the shade keep...
