Study Shows Weight Loss From Calorie Reduction Not Low Fat or Low Carb
Essentially the study showed that the calories had an impact on weight loss but the makeup of those calories did not. Don’t forget this is just one study. Listen to interview with the Author, Frank Sacks, on Science Friday on NPR.
Evolution, Methane, Jobs, Food and More

Science Friday is a great National Public Radio show. The week was a great show covering Antimicrobial Copper, Top Jobs for Math and Science, Human-Driven Evolution, Methane On Mars, Fish with Mercury and more. This show, in particular did a great job of showing the scientific inquiry process in action.
Very interesting stuff, listen for more details. A part of what happens is those individuals that chose to focus on reproducing early (instead of investing in growing larger, to reproduce later) are those that are favored (they gain advantage) by the conditions of human activity. I am amazed how quickly the scientists says the changes in populations are taking place.
And Methane On Mars is another potentially amazing discovery. While it is far from providing proof of live on Mars it is possibly evidence of life on Mars. Which would then be looked back on as one of the most important scientific discoveries ever. And in any even the podcast is a great overview of scientists in action.
StoryCorps: Passion for Mechanical Engineering
StoryCorps is an effort to record and archive conversations. NPR plays excerpts of one of the conversations each week, and they are often inspiring. They are conversation between two people who are important to each other: a son asking his mother about her childhood, an immigrant telling his friend about coming to America, or a couple reminiscing on their 50th wedding anniversary. By helping people to connect, and to talk about the questions that matter powerful recording are made. Yesterday I heard this one – A Bent For Building, From Father To Daughter:
Anne loved to take her things apart. It was mostly her toys — until the day she took a clock apart and spread its contents out.
When her father asked what had happened, his daughter answered, “Oh, I took it apart. Daddy fix.”
And as her dad put things back together, Anne would sit by, watching intently to see how things were made. “Did you ever notice that I always followed you around the shop, watching?” Anne asked Ledo.
“I thought there was a magnet hooked up to me and to you.”
Science and the City: Science Barge
Science and the City is (among other things) an excellent podcast series from the New York Academy of Science. The latest podcast discusses the science barge project we posted about earlier. They discuss looking at commercially viable urban farms (on rooftops in NYC) and the establishing educational gardens at schools.
See the Curious Cat Science and Engineering Podcast Directory for some great resources for podcasts. Don’t miss the naked scientists from the BBC.
Wabash Valley, Illinois Earthquakes
The Wabash Valley Seismic zone is adjacent to the more seismically active New Madrid seismic zone on the seismic zone’s north and west. The recent earthquake is also within the Illinois basin – Ozark dome region that covers parts of Indiana, Kentucky, Illinois, Missouri, and Arkansas and stretches from Indianapolis and St. Louis to Memphis. Moderately frequent earthquakes occur at irregular intervals throughout the region. The largest historical earthquake in the Illinois Basin region (magnitude 5.4) damaged southern Illinois in 1968. Moderately damaging earthquakes strike somewhere in the region each decade or two, and smaller earthquakes are felt about once or twice a year.
Earthquakes in the central and eastern U.S., although less frequent than in the western U.S., are typically felt over a much broader region. East of the Rockies, an earthquake can be felt over an area as much as ten times larger than a similar magnitude earthquake on the west coast.
The Woz Speaks
The Woz speaks at AlwaysOn 2006. Steve Wozniak, Apple co-founder, speaks on the development of the Apple II technology.
Science Education in the 21st Century
Science Education in the 21st Century: Using the Tools of Science to Teach Science podcast by Dr. Carl Wieman, recipient of the Nobel Prize in Physics in 2001. Also received the first NSF Distinguished teaching Scholars award (NSF’s “highest honor for excellence in both teaching and research”) and the National Professor Of The Year (CASE and Carnegie Foundation).
However, research is also providing insights on how to do much better. The combination of this research with modern information technology is setting the stage for a new more effective approach to science education based on using the tools of science. This can provide a relevant and effective science education to all students.

Quantum Mechanics Made Relatively Simple Podcasts
In 1999, legendary theoretical physicist Hans Bethe delivered three lectures on quantum theory to his neighbors at the Kendal of Ithaca retirement community (near Cornell University).
Intended for an audience of Professor Bethe’s neighbors at Kendal, the lectures hold appeal for experts and non-experts alike. The presentation makes use of limited mathematics while focusing on the personal and historical perspectives of one of the principal architects of quantum theory whose career in physics spans 75 years.
Soil Could Shed Light on Antibiotic Resistance
Soil Could Shed Light on Antibiotic Resistance, Science Friday podcast (7 minutes) from NPR. The podcast is an interview with Gerry Wright, McMaster University, Canada.
“New research points to drug resistance in soil-dwelling bacteria. Scientists say studying bacteria in the soil can help in understanding how the bacteria in humans develop resistance.”
