S&P 500 CEO’s: Engineers Stay at the Top

2008 Data from Spencer Stuart on S&P 500 CEO (link broken so it was removed, it is so sad that companies still pay people to manage web sites that don’t even understand basic web usability principles such as web pages must live forever) shows once again more have undergraduate degrees in engineering than any other field, increasing to 22% of CEO’s this year.

Field
	2008	2007	2006	2005
Engineering	22	21	23	20
Economics	16	15	13	11
Business Administration	13	13	12	15
Accounting	9	8	8	7
Liberal Arts	6	6	8	9
No degree or no data	3	3

In 1990 Engineering majors accounted for 6% of the bachelor’s degrees in the USA (1970 5%, 1980 7%). Business accounted for 23% of the majors in 1990 (1970 14%, 1980 21%). Liberal arts 3% in 1980 (1970 1%, 1980 2%).

The report does not show the fields for the rest of the CEO’s. 39% of S&P CEOs have MBAs. 28% have other advanced degrees. The University of Wisconsin-Madison and Harvard tied for the most CEO’s with undergraduate degrees from their universities at 13. Princeton and the University of Texas had 9 and Stanford had 8.

While the CEO’s have engineering education backgrounds the work they have done is often in other functions. The top function that CEO’s that have worked in during their careers: Operations (42%), Finance (31%), Marketing (24%), Sales (17%), Engineering (11%).

Sequences capture the code of the common cold

Conducted by teams at the University of Maryland School of Medicine, UW-Madison and the J. Craig Venter Institute, the work to sequence and analyze the cold virus genomes lays a foundation for understanding the virus, its evolution and three-dimensional structure and, most importantly, for exposing vulnerabilities that could lead to the first effective cold remedies.

“We’ve had bits and pieces of these things for a long time,” says Ann Palmenberg, of UW-Madison’s Institute for Molecular Virology and the lead author of the new study. “Now, we have the full genome sequences and we can put them into evolutionary perspective.”

As its name implies, the common cold is an inescapable, highly contagious pathogen. Humans are constantly exposed to cold viruses, and each year adults may endure two to four infections, while schoolchildren can catch as many as 10 colds.

“We know a lot about the common cold virus,” Palmenberg explains, “but we didn’t know how their genomes encoded all that information. Now we do, and all kinds of new things are falling out.”
…
The newly sequenced viruses also show, says Palmenberg, why it is unlikely we will ever have an effective, all-purpose cold vaccine: The existing reservoir of viruses worldwide is huge and, according to the new study, they have a tendency to swap genetic sequences when cells are infected by more than one virus, a phenomenon that can lead to new virus strains and clinical manifestations.
…
The ability of different cold virus strains to swap genes and make entirely new strains was thought to be impossible, notes Claire M. Fraser-Liggett, a co-author of the new study and director of the Institute for Genome Sciences and professor of medicine and microbiology at the University of Maryland School of Medicine. “There is the possibility that this could lead to the emergence of a new rhinovirus strain with fairly dramatic properties,” says Fraser-Liggett.

Promoting Bio-Literacy

Wisconsin State Herbarium tries to ‘counteract bio-illiteracy’

“In a past century people could go outside and name the flowers or trees,” said Ken Cameron, the herbarium’s director. “Now you take a kid outside and the most they can say is, ‘It’s a tree.’ If we can get students in and get them excited, then I think we’ve helped to counteract bio-illiteracy.”
…
Herbaria are becoming more of a rarity. And the UW-Madison has the third largest collection of any public university in the country, behind the universities of California and Michigan. At many universities, botany has been absorbed into large biology departments, and collections put into storage. That has not happened at UW-Madison.

“The combination of having a botany department and a big herbarium is getting pretty rare,” said David Baum, botany department chairman. “And more and more herbaria are closing or making the decision to move off campus into storage, which has a real negative effect on research.”

The University of Wisconsin-Madison Herbarium, founded in 1849 (the year the University was founded), is a museum collection of dried, labeled plants of state, national and international importance, which is used extensively for taxonomic and ecological research, as well as for teaching and public service. It contains the world’s largest collection of Wisconsin plants, about one-third of its 1,000,000 specimens having been collected within the state. Most of the world’s floras are well represented, and the holdings from certain areas, such as the Upper Midwest, eastern North America and western Mexico, are widely recognized as resources of global significance.

Soil Mineral Degrades the Nearly Indestructible Prion

Warped pathogens that lack both DNA and RNA, prions are believed to cause such fatal brain ailments as chronic wasting disease (CWD) in deer and moose, mad cow disease in cattle, scrapie in sheep and Creutzfeldt-Jakob disease in humans. In addition to being perhaps the weirdest infectious agent know to science, the prion is also the most durable. It resists almost every method of destruction from fire and ionizing radiation to chemical disinfectants and autoclaving, which reduce prion infectivity but fail to completely eliminate it.

Other studies have shown that prions can survive in the soil for at least three years, and that soil is a plausible route of transmission for some animals, says Joel Pedersen, a UW-Madison environmental chemist. “We know that environmental contamination occurs in deer and sheep at least,” he notes.

Prion reservoirs in the soil, Pedersen explains, are likely critical links in the chain of infection because the agent does not appear to depend on vectors — intermediate organisms like mosquitoes or ticks — to spread from animal to animal.

That the birnessite family of minerals possessed the capacity to degrade prions was a surprise, Pedersen says. Manganese oxides like birnessite are commonly used in such things as batteries and are among the most potent oxidants occurring naturally in soils, capable of chemically transforming a substance by adding oxygen atoms and stripping away electrons. The mineral is most abundant in soils that are seasonally waterlogged or poorly drained.

Correlation is Not Causation: “Fat is Catching” Theory Exposed

“Fat is catching” theory exposed

Their study was reported to have shown that you can “catch” obesity from having fat friends and that obesity is so contagious, it can be spread long-distance by email and instant messaging. Even healthcare professionals, who didn’t understand the etiology of true obesity or how statistics can be misused, failed to detect the implausibility of “second-hand obesity.” In fact, some doctors became so enamored with the new “science of networking” they believed it should be a new medical specialty: network medicine.
…
Jason M. Fletcher, Ph.D., assistant professor at the Yale School of Public Health in New Haven, Connecticut, along with Boston economist, Ethan Cohen-Cole, Ph.D., designed an ingenious study. They selected conditions that no one would seriously believe were spread by social networking and online friendships: height, headaches and acne. They then applied the same standard statistical methods used in Christakis and Fowler’s social networking research to “find” that acne, height and headaches have the same “social network effect.”
…
As they explained, patterns of association among people can lead to correlations in health conditions between friends that are not caused by direct social network effects at all.
…
There is a need for caution when attributing causality to correlations in health outcomes between friends using non-experimental data. Confounding is only one of many empirical challenges to estimating social network effects.

Excellent reminder of the risks of analyzing data for correlations. We continue to, far to often, fail to interpret data properly. Both authors of the study, received PhD’s from the University of Wisconsin-Madison which strengthens my belief that it is teaching students well (just kidding).

Also another example of the scientific inquiry process where scientists challenge the conclusions drawn by other scientists. It is a wonderful system, even if confusing and not the clean idea so many have of how science works.

Making Embryonic Stem Cells

Holy Grail of stem cell research within reach by Mark Johnson

It was time to test the 14 genes she had selected as the best candidates to reprogram a cell.

Using viruses to deliver the genes, she inserted all 14 at once into human cells. On the morning of July 1, 2006, Yu arrived at the lab and examined the culture dishes. Her eyes focused on a few colonies, each resembling a crowded city viewed from space. They looked like embryonic stem cells.
…
Cells must pass certain tests. They must multiply for weeks while remaining in their delicate, primitive state. When they are allowed to develop, they must turn into all the other cell types.

Bad things happen. Cells develop too soon. Cells die. There is no “aha!” moment, Thomson has said, only stress. He looked at the colonies and suppressed any excitement. He told Yu, essentially: OK, well get back to me in a couple of weeks.
…
In the fall of 2006, Yu was preparing to whittle down her list of genes when she fell ill. The pain in her gut was awful. She struggled to eat. Her doctor thought it was a stomach flu. Instead, in late October, Yu’s appendix burst. She was laid up for a month. When she returned to the lab, the problem with the culture medium struck again.

Not until January 2007 was she able to begin narrowing the list of genes. She spent several months testing subsets of them, finally arriving at four. Two, Oct4 and Sox2, were “Yamanaka factors,” the name given to the genes the Japanese scientist had used to reprogram mouse cells. Two, Nanog and Lin28, were not.

Using a virus to deliver the four genes, she reprogrammed a line of fetal cells, then repeated the experiments with more mature cells. Although the process was inefficient, succeeding with only a small fraction of cells, it did work.

Backyard Wildlife: Crows

bird dives at crow

Here is an action shot of a bird diving at a crow in my backyard, presumably to get the crow to leave. I noticed this for going on for several weeks (follow link for better view of the dive-bombing bird). The crow didn’t seem to mind too much most of the time.

I visited Madison this week and saw 4 wild turkeys wandering around in a residential area. I didn’t have my camera handy however, so I didn’t get a photo 🙁 It was a strange and cool site.

Crows Carry Cameras for Science:

The cameras look through the legs of the birds, transmitting what they record to a person holding a receiver several hundred meters away.
…
To understand more about how and why the crows use tools, researchers need a lot of details about their lives in the wild
…
Videos included footage of the crows using plant stems as tools to probe for food and even carrying a tool from one place to another. The images showed that birds on the ground pick up just 8 bits of food an hour.

Photos of Parfrey’s Glen, Wisconsin

See more photos from my visit to Parfrey’s Glen Natural Area in Wisconsin, about an hour outside of Madison. It really was amazingly beautiful – the pictures do not do it justice. The Parfrey’s Glen trail is under a mile but well worth visiting. If you want to hike more try the Ice Age National Scenic Trail or nearby Devil’s Lake State Park. The top photo is of me (John Hunter) at nearby Durwood’s Glen. The yellow flower is from Parfrey’s Glen.

Parfrey’s Glen is Wisconsin’s first State Natural Area, is a spectacular gorge deeply incised into the sandstone conglomerate of the south flank of the Baraboo Hills. The exposed Cambrian strata provide excellent opportunities for geological interpretation. The walls of the glen – a Scottish word for a narrow, rocky ravine – are sandstone with embedded pebbles and boulders of quartzite.

Finding the Host Genes Viruses Require

Flu-infected fly cells reveal dependencies of the virus

The new study is important because it demonstrates a rapid-fire technique for identifying host factors such as proteins and carbohydrates that a virus commandeers to successfully infect a cell. By exposing the virus’s dependencies, the Wisconsin team has uncovered a target-rich environment for influenza drug developers.
…
By working in fly cells, the Wisconsin team was able to deploy a technique to rapidly and selectively silence thousands of genes to see which were used by the flu virus. Screening a library of some 13,000 genes, the group identified more than 100 whose suppression in fly cells hindered the virus’s ability to successfully take over the cell and make new viruses.
