A Beverly Hills liposurgeon has been accused of using his patients’ liposuctioned fat to fuel his and his girlfriend’s SUVs. Perhaps the most surprising thing about this story is that no one came up with the lipo-fat-as-fuel idea before.

Give Dr. Alan Bittner this: He was never secretive about what happened to the leftover liposuction fat from his practice, Beverly Hills Liposculpture.  According to Forbes.com, he even ran a Web site dedicated to human fat fuel.  On the now defunct lipodiesel.com, Bittner wrote, “The vast majority of my patients request that I use their fat for fuel—and I have more fat than I can use… Not only do they get to lose their love handles or chubby belly but they get to take part in saving the Earth.”

Experts say animal fat is just as good as vegetable fat and a gallon of either will get you about the same mileage as a gallon of regular diesel.  The only caveat is that animal fat requires an additional processing step to remove free fatty acids.  Due to a recent surge in soybean oil prices, biodiesel manufacturers say that over half of this year’s biodiesel came from animal sources, such as pig lard.  Other new sources of biofuel include turkey feathers (see the DISCOVER story Anything Into Oil), coffee grounds, pond scum, and rainforest fungus.

Feeling stressed or sad? Before you succumb to the blues, try standing under a blue light. Several cities around the world claim to have reduced suicides, crime, and even traffic accidents by installing blue lights in the public spaces.

In Glasgow, Scotland, blue streetlights installed in 2000 have reduced street crimes noticeably. In Japan, a country notorious for its high suicide rates—authorities say in 2007 alone there were 640 suicides attempted by jumping in front of oncoming trains—two railroad companies have turned to light therapy. After blue lights were installed on station platforms and near railway crossings, the number of suicide attempts dropped to zero. Also in Japan, hundreds of blue lights have been installed along highways and rest stops. An expressway operator said trash cans near blue lights received 20 percent less garbage.

Jun Wang dumped fuel from his tanker trunk into Little Beaver Creek in Kettering, Ohio. Allesandro and Carlos Giordano, a father and son team, imported and sold cars that didn’t meet U.S. emissions standards. These are just some of the characters on the Environmental Protection Agency’s new “Most Wanted” list of environmental fugitives.

The list is posted on the agency’s website and includes mugshots of 23 people along with their alleged violations and suspected whereabouts. And the EPA wants your help in capturing them. The Web site has information on who to call if you see any of the suspects—it’s usually the Criminal Investigation Division office in the city where they were charged. There are also Wanted posters you can print out.

But don’t, they warn, take green justice into your own hands:

Last week a band of Somali pirates hijacked a Saudi Arabian tanker in just 16 minutes using Kalashnikovs and rocket launchers. This was just one of around 100 attacks in the area this year—leaving plenty of fear that the pirates are on their way to sabotaging one of the most important sea trade routes in the world. But the days of pirate victories may soon be over, thanks to a little scientific ingenuity. A British company called Anti-Piracy Maritime Security Solutions thinks the outlaws can be taken down using none other than a high-tech “sonic laser.”

Their plan is this: Hook up a long-range acoustic device (LRAD) to an MP3 player, and raise the volume to painful sound levels whenever pirates approach. The noise from the satellite dish-sized LRAD can get so loud that it causes permanent hearing damage. If threatened ships blast oncoming pirates with “precise beams” of warning messages, sirens, etc., it could be enough to cause “absolute agony” to any ambitious pirates, according to APMSS chief executive Nick Davis, and could make them turn back.

While anti-pirate sound doesn’t come cheap—the team and equipment costs $21,000 for three days of use—the technology is in high demand, with APMSS sending 10 teams out on on ships in the Gulf of Aden this week. Let’s just hope they’re armed with good ear plugs.

Look for this in a future episode of CSI: Detectives expose a piece of paper, a shard of glass, or even a scrap of fabric to a chemical vapor, and within hours, dark brown fingerprints appear. Scientists in the UK report a new method of fingerprint detection that makes fingerprints on almost any material visible to the naked eye. But that’s not all: They say the same method can also read a sealed letter without opening the envelope.

Researcher Paul Kelly stumbled upon the discovery while studying the compound disulfur dinitride. His team first noticed the compound’s fingerprint imaging properties on laboratory glassware. When exposed to vapors of the compound, even in low concentrations, fingerprints left on the glassware would stain a dark brown. Residues from the fingerprints were causing disulfur dinitride to form a dark brown polymer.

Just as the Census of Marine Life announces the existence of amazing new wonders in the Southern Oceans, a battle over the oceans’ largest inhabitants rages on. While many have criticized Japanese whalers for illegally terrorizing (and slaughtering) whales, the Japanese are now turning the tables and accusing the television channel Animal Planet of terrorizing their whaling ships.

The accusations stem from Animal Planet’s new seven-part series, Whale Wars, which documents the militant anti-whaling escapades of the Sea Shepherd Conservation Society. The Sea Shepherds have been using harsh and combative— though, they insist non-violent—strategies like hurling stink bombs, throwing acid, and spreading propeller-tripping steel cables to stop Japanese whaling ships from doing their job. The group says they prevented 300 whale deaths last winter. Japanese whalers have killed thousands of whales since the 1980s, and claimed they were in the name of research.

Murderers desperate to get rid of evidence might want to consider using bleach to wash away stains. But not just any bleach will do. When old-school chlorine-based bleach is splashed all over blood-stained clothing, even if the clothes are washed ten times, DNA is still detected.

So for the criminal aspiring for perfection, here’s the secret you’ll need to know: It’s the oxygen-producing detergents that will get rid of any incriminating evidence for good.

Researchers at the University of Valencia tested oxygen bleach on blood-stained clothing for two hours and found that it destroys all DNA evidence. Forensic tests such as luminal tests rely on the ability of blood to uptake oxygen: A protein in the blood called hemoglobin (responsible for transporting oxygen throughout the body) reacts with hydrogen peroxide and gives a positive test result.

Have you seen this child—looking like this? A new study suggests authorities are using the wrong kind of photos to locate missing children. Parents of missing children are usually asked to provide a recent school photo, which typically show smiling, clean, and dressed-up children. But these photos don’t accurately depict the state of kidnapped children (which is what the average missing child would be), who usually look upset, tired, and unkempt.

Researchers at Mississippi State University asked 150 adults to look at photos of children, some in “clean” states and others in “dirty” states. (For the “dirty” states, the children were photographed with makeup to simulate dirt and bruises.) The adults were then shown another set of photos and asked if they recognized the children from the previous photos. People were better at recognizing children shown in similar states, and the advantage became more apparent when the researchers inserted a delay (10 minutes, 3 weeks, 6 weeks, or 12 weeks) between the two sets of photos. This means that even someone who has seen a picture of a missing child might easily overlook the same child on the street.

If you’re flying to Australia anytime soon, be prepared to show a lot of skin at the airport. From now until the end of November, Melbourne airport is testing out new X-ray scanners that can see through clothing and leave little to the imagination. The scanners may soon replace pat downs with “virtual strip searches,” which officials say will save time at security check points. For the trial period, only passengers who volunteer will be scanned.

The full-body scanners use low-energy X-rays that reflect off skin to provide chalky images of naked bodies. They will reveal any hidden objects, even nonmetal ones that would be bypassed by traditional metal detectors.
