KDVS Annual Fundraiser On Now
Hey everyone…
Every year, KDVS, the radio station that This Week in Science calls home has a fundraising drive. It’s that time of year again.
For the week, volunteers will be at the station answering phones, taking donations, and generally working their butts off to support the station. The goal is to raise $60,000.
That’s a small sum compared to so many other things in this world. It’s significantly less than most households in the San Francisco Bay Area make in a year.
In return for support, those who donate will receive gifts that have been specially chosen by people who work at the station. The music directors have put together amazing music packages, djs have crafted their own t-shirts and cds. Hundreds of hours of love and dedication have already gone into making this week something special with no expectation of gain in return other than to keep the station thriving.
That’s what is so special about KDVS. It is non-commercial, independent, free-form radio, and the people who work at the station truly love to be there.
So, show your support for the concept of KDVS, for the home of TWIS, for a station that continues to put science on the radio… donate.
Any amount is great, but we hope that people will be able to give $25 as students or $40 as community members.
TWIS is offering a limited number of the 2009 Science Music Compilation CDs as our special gift to people who donate at the student or community level in support of our show.
You can donate online here.
Oh, and PS… It’s tax-deductible.

Hey Everyone!
I’d like to invite you to join the new TWIS book club.
We’ll be reading a book a month about something science-y. At the end of each month we will get together online and discuss the books and the science. I’m really looking forward to getting to hear what others think about the books we read, and sharing my thoughts with other people.
So, check it out if you are so inclined. Let’s get smart together!

Persistent Free Radicals – Chemists have discovered a new class of air pollutant, persistent free-radicals, which form and last on fine airborne particles indefinitely, and might contribute substantially to cardio-pulmonary diseases.
Flesh-eating Bacteria’s Weapon Figured Out – Flesh-eating bacteria release a special compound called Strep pyogenes cell envelope protease or SpyCEP for short, which inactivates white blood cells and blocks the body from defending itself against the necrotizing infection.
Memory of a Robot Brain – Scientists are figuring out how the brain works by using rat brain cells to control a robot.
How to Stop Addiction – Researchers kept mice from becoming addicted to cocaine by blocking glutamate receptors on dopamine producing brain cells.
Eyes Do More than See – Mice were switched from night to daytime activity by messing with the amount of light in the room and the sensitivity of their eyes to light suggesting that they eyes play a major role in setting the body’s internal clock.
Depression is Bad for Driving – A study of 60 individuals found that people who were depressed and taking anti-depressant medication performed worse on simulated driving tests than both medicated and unmedicated individuals who weren’t depressed. So, don’t be depressed and drive.
Humans Like Pretty People – Analysis of contestant behavior on a Dutch game show called Shafted supports the idea that humans have a bias for beautiful people.
Beer Goggles – Beer goggles are for real! Drunk students rated pictures of people of both sexes more attractive.
A Reason For Sexual Preference? – Homosexual and bisexual men had female relatives with more children than heterosexual men. So, whatever makes women like men and have more children might make men like men as well.
Smell What You Like? –If you’re a woman on the contraceptive pill, you could be with the wrong partner. Women preferred different body odors before and after beginning to take the pill. It’s thought that women use smell to choose an immunologically compatible partner.

Where For Art Thou Meteorite? – Meteorites that landed here on earth are more like the space rocks in the asteroid belt between Mars and Jupiter than like low metal content LL chondrite asteroids found closer to the earth.
Something Like a Comet – Researchers using the Sloan Digital Sky Survey reported finding a comet-like object in a 22,500 year orbit around the sun. It doesn’t have a comet tail because it never gets close enough to the sun.
How to Get There – Theoretical physicists have come up with a new idea for space travel. They suggest manipulating dark energy through another dimension of space, shrinking space in front of a ship and expanding it behind. The trouble is that it requires a quantity of energy equal to converting something like the planet Jupiter into pure energy.
Entangled particles really are “spooky” – Nothing travels faster than light, but two entangled particles separated by 18 kilometers and located in two different Swiss towns were able to communicate with instantaneous precision, thereby validating quantum mechanics and spooky action at a distance.

Nanotubes Are Strong – Experiments at Northwestern University proved that carbon nanotubes really are as strong as calculations predicted, and that radiation makes them even stronger. I’m still waiting for that space elevator.
A Limit to Tall – Physics imposes a limit on the height of trees. The maximum height to which Douglas Firs should be able to transport water is between 131 to 145 meters. That’s also the limit of their height.
Nature is the Best Teacher – Scientists mimicked photosynthesis in the lab, and were able to split water into hydrogen and oxygen using the power of light.
Asphalt into Energy – Hot asphalt roads and parking lots may produce energy one day. Scientists are experimenting with the idea of adding a heat exchanger that would convert the heat absorbed by asphalt into energy.
Planet Friendly Paper Coating – A replacement for the waterproof wax coating that’s used on paper products like drink boxes has been created from the lignin of sugarcane, which unlike wax leaves the paper it coats completely recyclable.
The Effect of Climate change – A recent study found that 9 out of 10 tree species measured in the Santa Rosa mountains of California have increased the elevation of their habitat by 213 feet. The change in growing range was linked to changes in local climate.
Antarctica is not Alone – Ice cores revealed that West Antarctica is highly affected by atmospheric and oceanic changes in the tropics of the Pacific Ocean.
Dead Zones of the World – The number of oxygen poor dead zones in the world’s oceans has doubled to 400 in just the past two years. These dead zones are linked to algae blooms fed by fertilizer run-off, sewage, and the burning of fossil fuels.

I’ve published another set of Science Word videos… the science headlines in brief. Here’s the first of the set of four:
Hubble Space Telescope – What’s up in space, travels 5 miles per second, and has offered us an unparalleled view of our universe? The Hubble Space telescope, which just passed 100,000 times around the planet.
Size Doesn’t Matter – In nanotech, it’s apparently not the size of the particle that determines cell penetration, but the shape. Rods do much better than spheres.
Invisibility? – Harry Potter might have worn invisibility chain mail instead of a cloak if J.K Rowling had been paying attention to science. Researchers have created a new metal material that bends light backwards through electromagnetic interactions with the light istelf.
Large Hadron Collider – The Large Hadron Collider will officially begin operations on September 10th, but won’t get to full strength until sometime next spring.
Bicycle Saddles and the Police – The results are in… bike seats without noses keep bike cops frisky. Cops testing the special saddles had less genital numbing and better penile sensation.
Is Infertility Treatment Worth It? – Intrauterine insemination was only 6% more effective in producing a live birth than no treatment at all in a group of 580 women experiencing unexplained infertility. However, women who had insemination felt more reassured during the process.
Females Are The Same – Sexual harassment doesn’t just bother human females. It also bugs female guppies who tend to prefer the risk of being eaten to hanging out around pushy males.
Complete Neanderthal Mitochondrial Genome – The most complete and accurate Neanderthal mitochondrial genome to date was produced from a 38,000 year old fossil. Whether or not humans and Neanderthals ever got jiggy wid it is still in question.
A Pill For Alcoholics – Researchers in Oregon are testing a drug called CRF 154,526, which blocks all of the good, but none of the bad effects of alcohol– none of the euphoria, and the hangover’s still waiting. They say CRF is meant for treating hedonistic dysregulation.
Gene Link to Smoking Addiction –
People who say they got hooked on the first puff of a cigarette are likely to have a gene variant called CHRNA5.

First Star in Universe Grew Fast – Computer simulations suggest the first stars started small, but grew 100 times larger than our sun in just 10,000 years.
Duck-Billed Dinos Outgrew Predators – Best predator defense? Grow fast and make babies. That’s what the duck-billed hadrosaur did as it grew up to 4.4 tons in 2-3 years. Gives a new meaning to “eat my dust.”
Moss, Insect Fossils Evince Once-Living Antarctica – Researchers found freeze-dried moss, crustaceans, insects, and pollen trapped in the glacial ice. 14 million years ago Antarctica was much warmer.
Hostile-to-Life Substance Found in Martian Soil – NASA thought they could grow vegetables on Mars, but then discovered perchlorate, a component of rocket fuel, in one of their tests. They have decided to perform more tests.
Dark Energy’s Fingerprint Found in Distant Galaxies – Researchers have made one of the most statistically probable measurements of dark energy to date, but they still don’t know what it is.
X-rays reveal Van Gogh portrait – A particle accelerator was used to blast a Van Gogh painting with high intensity x-rays. A second painting was discovered beneath the outer surface of paint.
‘Laser jumbo’ testing moves ahead – The US Air Force has begun fuel tests of their Airborne Laser system, which is designed to shoot down ballistic missiles from the inside of a 747 aircraft.
