 Write a Review of Science Friday Podcast
Always a good listen, September 26, 2007
Reviewer: ckazilek
This is one show that always has some great content. I look forward to Fridays.
 
Solid content; some discretion advised, September 17, 2007
Reviewer: jct405
An earlier reviewer's critique labeling this program 'poor science' was based on one program. One would have to agree with him that it is frustrating to waste time listening to shoddy science. But do not throw the baby out with the bathwater. Mr. Flatow has interviewed many, many good scientists along with a few nimrods. His recent interview of Jonathan Graff is one darn good reason to listen regularly. Graff's team at UTSW has published a stunningly important finding: a gene that regulates fat accumulation and metabolism in organisms from fruit flies, worms and mammals that could reasonably (given the current findings) turn out to be the cure for diabetes. It has all the markings of rigorous scientific investigation. And what is more interesting is that the major media has yet to pick up on it. Good work, Mr. Flatow! Yes, screen out the nimrods. But, wow, keep this stuff coming. Thanks.

There is really something for everyone in these shows. From leeches and stem cells, to new planets and weight reduction surgery, Science Friday covers a wide range of topics in layman’s terms. The host’s inquisitive and direct questions dissect the issues and help to shed light on the mystery of everyday and esoteric science and related issues. Never boring and always chock full of info, these are a great listen.

Scientists Mark 25 Years of HIV Research
Fri, May 09, 2008
In May 1983, the first scientific papers were published describing the possible connection between a retrovirus and the development of AIDS. The virus went on to become known as HIV. Experts discuss whether, 25 years later, scientists any closer to a cure for AIDS or to a vaccine to prevent HIV transmission.

Study: Sahara Gradually Dried Up Over 6,000 Years
Fri, May 09, 2008
What made the Sahara Desert go dry — and are there ancient waters still hidden below the sands? In a controversial study published in the journal Science researchers argue that the drying of the Sahara took place over thousands of years — not suddenly as was previously thought.

Mysterious Memristor: Electronics' Missing Link?
Fri, May 09, 2008
Introductory electronics classes focus on circuit diagrams involving combinations of resistors, capacitors and inductors. Now, researchers have discovered a fourth passive circuit element — one that fills in a gap in equations describing relationships between voltage, current and magnetic flux.

Common Weedkiller May Cause Hormonal Problems
Fri, May 09, 2008
Researchers report that atrazine, the second-most-applied weedkiller in the U.S., may be able to disrupt hormonal signaling in humans. The herbicide, which has been banned in Europe, is suspected of playing a role in sexual abnormalities in fish, frogs and other aquatic organisms.

Is It Better to Eat Locally or Eat Differently?
Fri, May 09, 2008
When it comes to greenhouse gas emissions, what you eat may be more important than where your food comes from. A new study finds that replacing red meat and dairy products with chicken, fish or vegetables could have the same impact as shifting to an entirely locally-grown diet.

Advances in Gene Therapy Treatment for Blindness
Fri, May 02, 2008
Researchers using a gene therapy technique to treat one form of congenital blindness have reported some success. Two teams of scientists have used modified viruses injected into the eye to partially restore vision to people who have Leber congenital amaurosis, an illness that results in the degradation of the retina.

T. Rex Protein Evidence Links Dinosaurs to Birds
Fri, Apr 25, 2008
Analysis of proteins found in a scrap of collagen from a 68-million-year-old Tyrannosaurus rex leg bone provides strong evidence for the idea that dinosaurs are the ancestors of modern-day birds. Paleontologist Mary Higby Schweitzer talks about the finding and what it means for our understanding of evolution.

PETA Offers Incentive for Test-Tube Meat Research
Fri, Apr 25, 2008
Animal rights group PETA is offering a $1 million prize for the development of commercially-viable "test-tube meat" — real meat grown through a lab process, not from a live animal. To win, the lab-grown meat must have a taste and texture indistinguishable from real chicken flesh.

Pine Forests Destroyed by Beetle Takeover
Fri, Apr 25, 2008
Canadian forests are being hit hard by an outbreak of the mountain pine beetle. Though the beetles are small — less than 1/3 of an inch long — they're hungry, and bore through the wood of a variety of pine tree species. Ecologists are worried that the death of so many trees will have a significant impact on the carbon balance in North America.
