Five-Star Friday: cancer centers, precision medicine, stem cell soup, and why science isn’t broken

Last week we reviewed three top-rated five-star stories on the site. This week we didn’t have anything that topped three stars cross our radar. That doesn’t mean there weren’t reporters and news release writers putting out exemplary pieces about health care — merely that we didn’t have an opportunity to review them. Show More Summary

5-Year-Old Girl's Stem Cells Help Put Twin Brother's Cancer In Remission

18 hours agoNews : Huffington Post

Sharing is caring, and no one knows that better than these young twins. When 5-year-old Bradley Godish required a stem cell transplant to help eliminate his leukemia, his twin sister, Charlotte “Charlie,” was the first to step up to the plate as the donor, WGN-TV reported. Show More Summary

Five-Year-Old’s Decision to Donate Stem Cells to Her Twin Brother With Cancer Saved His Life

In Illinois, a five-year-old girl made the selfless decision to give her twin brother her stem cells to help him fight an aggressive form of leukemia. In 2014, Bradley Godish was diagnosed with acute myeloid leukemia, which is the second most common form of leukemia in children. His parents asked his twin sister, Charlotte, if […]

Image-tracking technology helps scientists study nature v. nurture in neural stem cells

One of the longstanding debates in science, that has, perhaps unsurprisingly, permeated into the field of stem cell research, is the question of nature versus nurture influencing development. Science on stem cells thus far, has suggested that, as one side of the existential debate holds: their fate is not predestined. Show More Summary

Variations in Cell Programs Control Cancer and Normal Stem Cells

In the breast, cancer stem cells and normal stem cells can arise from different cell types and tap into distinct yet related stem cell programs, according to Whitehead Institute researchers. The differences between these stem cell programs may be significant enough to be exploited by future therapeutics.

Eating baked purple potatoes is discovered to fight cancer

According to Penn State News, baked purple potatoes are discovered by researchers to contain compounds that can help kill colon cancer stem cells and limit the spread of the cancer. The superfood that originally comes from South America is packed with antioxidants that kills tumors

Ars is hiring! Can you handle healthcare?

We're looking for a reporter who can nimbly leap from stem cells to Fitbits.

California's Stem Cell Bank is Open for Business

The largest publicly available stem cell bank in the world is now open for business. In September the bank is offering the first 300 different stem cell lines for researchers interested in gaining a deeper understanding of, and developing treatments for 11 common diseases and disorders.

Multiple Sclerosis vs. California's Stem Cell Agency: Disease-a-Week Challenge No.15

"He was born with the gift of laughter, and the sense that the world was mad." -- Rafael Sabatini That opening line (from the novel Scaramouche) would seem to have been written for the comedic genius Richard Pryor. His life was almost...Show More Summary

Come here and be quiet! Genes physically held in silencing 'lock-down' in embryonic stem cells

A strong physical gene interaction network has been discovered that is responsible for holding genes in a silencing grip during early development. In the same way that people can interact with others in close proximity, say within the...Show More Summary

Regular Stem Cell Transplants Extend Life in Normal Rats

4 days agoHealth / Aging : Fight Aging

Researchers here demonstrate extended life spans in rats as a result of life-long regular transplantation of stem cells. The specific mechanisms are unknown, but the researchers suggest that the proximate causes involve altered levels of various signal molecules leading to better operation and maintenance of native cells and tissues.

Generating potentially safer stem cells in the laboratory

A finding reveals why the transformation process of differentiated cells into stem cells results in significant damage to the DNA. Researchers have managed to rectify this damage using a simple modification to the culture medium, which produces potentially safer stem cells for use in regenerative medicine.

Researchers Mimic Viral Infection in Colon Cancer Stem Cells

Researchers targeting colorectal cancer stem cells - the root cause of disease, resistance to treatment and relapse - have discovered a mechanism to mimic a virus and potentially trigger an immune response to fight the cancer like an infection.

Morality bank in China rewards do-gooders

A rewards system in Yanji, China accredits points to individuals who do good — from mowing lawns to donating stem cells.

Colorful potatoes may pack powerful cancer prevention punch

Compounds found in purple potatoes may help kill colon cancer stem cells and limit the spread of the cancer, according to a team of researchers.

The Problem With Protein

Will growing hamburgers in Petri dishes be the solution to our future food demand? "Stem cell sliders" may sound laughable now, but not when confronted with the need to double global food production by 2050. With a population projected...Show More Summary

UCSF Researchers Control Embryonic Stem Cells with Light

UC San Francisco researchers have for the first time developed a method to precisely control embryonic stem cell differentiation with beams of light, enabling them to be transformed into neurons in response to a precise external cue...

A Boy Who Asked Obama About Stem Cell Research In 2007 Writes To Say It Saved His Life

A young cancer survivor sent President Barack Obama a moving letter thanking him for keeping a promise made during a 2007 campaign stop -- a promise the boy says saved his life. Gavin Nore, a teen from Fort Dodge, Iowa, told Obama in...Show More Summary

How do harmful chronic myelogenous leukemia stem cells obtain their nutrients?

Medical researchers have found a novel nutrient uptake process that maintains the activity of murine chronic myelogenous leukemia (CML) stem cells. Pharmacological inhibition of nutrient uptake decreased CML stem cell activity. Certain nutrients support CML stem cell activity in vivo, thus pointing towards a potential therapeutic target for CML therapy.
