Damage Control: Recovering from Radiation And Chemotherapy
Published: May 1, 2014.
Released by University of California - San Diego
Researchers at the University of California, San Diego School of Medicine report that a protein called beta-catenin plays a critical, and previously unappreciated, role in promoting recovery of stricken hematopoietic stem cells after radiation exposure.

Why the Seahorse's Tail Is Square
Why is the seahorse's tail square? An international team of researchers has found the answer and it could lead to building better robots and medical devices. In a nutshell, a tail made of square, overlapping segments makes for better armor than a cylindrical tail. It's also better at gripping and grasping. Researchers describe their findings in the July 3 issue of Science.
We're Not Alone - but the Universe May Be Less Crowded Than We Think
There may be far fewer galaxies further out in the Universe then might be expected, suggests a new study based on simulations conducted using the Blue Waters supercomputer at the National Center for Supercomputing Applications, with resulting data transferred to SDSC Cloud at the San Diego Supercomputer Center at the University of California, San Diego, for future analysis.
Protein's Impact on Colorectal Cancer Is Dappled
Researchers at University of California, San Diego School of Medicine have discovered a cell signaling pathway that appears to exert some control over initiation and progression of colorectal cancer, the third leading cause of cancer-related death in the United States. A key protein in the pathway also appears to be predictive of cancer survival rates. The study is reported in the June 30 issue of eLife.
Exit Dinosaurs, Enter Fishes
A pair of paleobiologists from Scripps Institution of Oceanography, UC San Diego have determined that the world's most numerous and diverse vertebrates ¬- ray-finned fishes - began their ecological dominance of the oceans 66 million years ago, aided by the mass extinction event that killed off dinosaurs.
Flatworms Could Replace Mammals for Some Toxicology Tests
Laboratories that test chemicals for neurological toxicity could reduce their use of laboratory mice and rats by replacing these animal models with tiny aquatic flatworms known as freshwater planarians.
Braking Mechanism Identified for Cell Growth Pathway Linked to Several Cancers
Researchers at University of California, San Diego School of Medicine have discovered a self-regulating loop in the Hippo pathway, a signaling channel garnering increased attention from cancer researchers due to its role in controlling organ size, cell proliferation and cell death.
Multiple Pathways Progressing to Alzheimer's Disease
The amyloid cascade hypothesis of Alzheimer's disease (AD) posits that sticky aggregations or plaques of amyloid-beta peptides accumulate over time in the brain, triggering a series of events that ultimately result in the full-blown neurodegenerative disorder. The hypothesis has been a major driver of AD research for more than 20 years.
Electrical Engineers Break Power And Distance Barriers for Fiber Optic Communication
Electrical engineers have broken key barriers that limit the distance information can travel in fiber optic cables and still be accurately deciphered by a receiver. Photonics researchers at the University of California, San Diego have increased the maximum power -- and therefore distance -- at which optical signals can be sent through optical fibers. This advance has the potential to increase the data transmission rates for the fiber optic cables that serve as the backbone of the internet, cable, wireless and landline networks.
