Technology is transforming the way companies do business, creating new risks and opportunities.
Helen Teague's insight:

Post by Catherine Bolgar : The Internet is estimated to have accounted for 21% of economic growth in mature economies from 2006-2011...“The mistake businesses make is they assume technology is the answer,” Mr. Collins says. “Technology merely enables the answer. The answer is how do people interact and react to the world around them. The technology has to support customer demands and needs, even if the customer doesn’t know they need it today. The customer didn’t know what the Internet was until it appeared. Once it appeared it became indispensable.”

Especially  helpful are the steps for companies to take to remain nimble.

Study shows how epigenetic memory is passed across generations

Study shows how epigenetic memory is passed across generations | Thinking, Learning, and Laughing | Scoop.it

A growing body of evidence suggests that environmental stresses can cause changes in gene expression that are transmitted from parents to their offspring, making "epigenetics" a hot topic. Epigenetic modifications do not affect the DNA sequence of genes, but change how the DNA is packaged and how genes are expressed. Now, a study by scientists at UC Santa Cruz shows how epigenetic memory can be passed across generations and from cell to cell during development.

The study, published September 19, 2014 in Science, focused on one well studied epigenetic modification--the methylation of a DNA packaging protein called histone H3. Methylation of a particular amino acid (lysine 27) in histone H3 is known to turn off or "repress" genes, and this epigenetic mark is found in all multicellular animals, from humans to the tiny roundworm C. elegans that was used in this study.

 

"There has been ongoing debate about whether the methylation mark can be passed on through cell divisions and across generations, and we've now shown that it is," said corresponding author Susan Strome, a professor of molecular, cell and developmental biology at UC Santa Cruz.

 

Strome's lab created worms with a mutation that knocks out the enzyme responsible for making the methylation mark, then bred them with normal worms. Using fluorescent labels, they were able to track the fates of marked and unmarked chromosomes under the microscope, from egg cells and sperm to the dividing cells of embryos after fertilization. Embryos from mutant egg cells fertilized by normal sperm had six methylated chromosomes (from the sperm) and six unmarked or "naked" chromosomes (from the egg).

 

As embryos develop, the cells replicate their chromosomes and divide. The researchers found that when a marked chromosome replicates, the two daughter chromosomes are both marked. But without the enzyme needed for histone methylation, the marks become progressively diluted with each cell division.

 

"The mark stays on the chromosomes derived from the initial chromosome that had the mark, but there's not enough mark for both daughter chromosomes to be fully loaded," Strome said. "So the mark is bright in a one-cell embryo, less bright after the cell divides, dimmer still in a four-cell embryo, and by about 24 to 48 cells we can't see it anymore."

 

The researchers then did the converse experiment, fertilizing normal egg cells with mutant sperm. The methylation enzyme (called PRC2) is normally present in egg cells but not in sperm, which don't contribute much more than their chromosomes to the embryo. So the embryos in the new experiment still had six naked chromosomes (this time from the sperm) and six marked chromosomes, but now they also had the enzyme.

 

"Remarkably, when we watch the chromosomes through cell divisions, the marked chromosomes remain marked and stay bright, because the enzyme keeps restoring the mark, but the naked chromosomes stay naked, division after division," Strome said. "That shows that the pattern of marks that was inherited is being transmitted through multiple cell divisions."

This popped up in my KM daily feed, and so I simply had to pass it along!


Position Available Immediately: Apprentice Sith Lord, Dark Side Consulting Group

An unprecedented opening has occurred in the Dark Side Consulting Group for an Apprentice Sith Lord. The ideal candidate for this position would like galactic travel, and possess a complete understanding of and competence with the force, or demonstrate a willingness to learn.


Duties include: Performing competitive intelligence, hands-on
intervention in support of the Sith Master's planning initiatives,
ability to travel the galaxy widely, and operating a variety of
laser-powered hand weapons and high-powered space/air vehicles. Some slaying of enemies of the Dark Side is also required, though may be performed using the force, or hand weapons.

Qualified applicants would possess good communications skills
(especially when speaking in menacing whispers), and would be
action-oriented individuals and risk takers. A background in study of the force (light side or dark) is desirable, as would typically be acquired by those with advanced degrees or significant coursework in Jedi Arts from the University of Coruscant. Applicants should also be familiar with holographic projection equipment, possess a valid galactic pilot's license (for all classes of ships), and must show a willingness to give in to their hate.

A proven track record of using fear and/or jedi mind tricks to control others is also desirable, as is the ability to speak several galactic languages.

Ideal candidates for this position would also have no children, or
other living relatives who are strong in the ways of the force. (A new hire would be given several weeks to meet this requirement.) Compensation for this position is commensurate with experience, and is extremely competitive for this field. Benefits include a generous severance package, a company starship, and a dark-colored clothing allowance.

The Apprentice Sith Lord reports to and works closely with the Sith Master, and experience in such small, team-based organizations is vital to the success of the master's plans. Discretion is also highly valued, as is the ability to see the future before it happens.

Applications will be accepted until the end of June. Transmit them holographically to: jobs@darkside.com

*******************************************************************
Dark Side CG (tm) is a small and highly-focused organization, founded a long time ago. Our core values reflect the short-term advantages of harnessing hate for institutional power, and the long-term desirability of controlling the galaxy. We provide direction to our partner organizations through knowledge management, incident control and our rapid on-site intervention expertise. Our partnered organizations include the Imperial Senate, the Hutt Gambling Collective of Tattooine, and many large software companies.
