Single-use Bioreactor System Enhances Cell Culture Performance

May 23, 2014 12:32 pm | Product Releases | Comments

Pall Corporation offers the XRS 20 Bioreactor System, a  bioreactor with unique agitation properties that incorporates a single-use, easy-to-use Allegro 3-D biocontainer. This next generation “rocker” bioreactor is designed for cultivation of mammalian cells in suspension culture.

Misguided DNA-Repair Proteins Caught in the Act

May 23, 2014 12:06 pm | News | Comments

Accumulation of DNA damage can cause aggressive forms of cancer and accelerated aging, so the body’s DNA repair mechanisms are normally key to good health. However, in some diseases the DNA repair machinery can become harmful. Now, scientists have discovered some of the key proteins involved in one type of DNA repair gone awry.

Study Shows How Common Obesity Gene Contributes to Weight Gain

May 23, 2014 12:01 pm | News | Comments

Researchers have discovered how a gene commonly linked to obesity—FTO—contributes to weight gain. The study shows that variations in FTO indirectly affect the function of the primary cilium, a little-understood hair-like appendage on brain and other cells.

Researchers Identify Key Mechanism in Metabolic Pathway that Fuels Cancers

May 23, 2014 11:41 am | News | Comments

In a discovery at the Children’s Medical Center Research Institute at UT Southwestern (CRI), a research team has taken a significant step in cracking the code of an atypical metabolic pathway that allows certain cancerous tumors to thrive, providing a possible roadmap for defeating such cancers.

Fruit Flies “Think” Before They Act

May 23, 2014 11:24 am | News | Comments

Oxford University neuroscientists have shown that fruit flies take longer to make more difficult decisions. In experiments asking fruit flies to distinguish between ever closer concentrations of an odor, the researchers found that the flies don’t act instinctively or impulsively. Instead they appear to accumulate information before committing to a choice.

Alzheimer’s, Other Conditions Linked to Prion-like Proteins

May 23, 2014 11:22 am | News | Comments

A new theory about disorders that attack the brain and spinal column has received a significant boost from scientists. The theory attributes these disorders to proteins that act like prions, which are copies of a normal protein that have been corrupted in ways that cause diseases.
