<p>Science brought us snotty weapons, computers with DNA and UFOs over Texas. And this is just a few of the stories we found.</p><p> Check these out.</p>
Deadly medical mystery solved
<p> A blood type that can turn blood transfusions deadly has proven a perplexing mystery for 60 years. Now researchers have finally identified the secret behind the blood type known as "Vel," findings that could help make blood safer for hundreds of thousands of people worldwide.</p>
<p> The mystery began in 1952, when a 66-year-old woman in New York, sick with colon cancer, received a blood transfusion and unexpectedly suffered from a severe and potentially fatal rejection of the blood. Investigators referred to her, using her last name, simply as Patient Vel.</p>

Snotty weapon found
<p> Spiny lobsters have hard shells and strong jaws easily capable of turning the soft-bodied, sluglike sea hare into an easy meal. But new research finds that sea hares have a snotty solution: Clog up potential lobster predators' nostrils.</p>
<p> When threatened, the sea hares excrete a white, sticky substance called opaline that stuffs up the lobsters' sensory organs. While the lobster struggles to deal with this sudden lack of smell, the sea hare can often escape its clutches.

Green meteorite from Mercury?
<p> Scientists may have discovered the first meteorite from Mercury.</p>
<p> The green rock found in Morocco last year may be the first known visitor from the solar system's innermost planet, according to meteorite scientist Anthony Irving, who unveiled the new findings this month at the 44th annual Lunar and Planetary Science Conference in The Woodlands, Texas. The study suggests that a space rock called NWA 7325 came from Mercury, and not an asteroid or Mars.

Will next computers be alive?
<p> The transistor revolutionized electronics and computing. Now, researchers have made a biological transistor from DNA that could be used to create living computers.</p>
<p> A transistor is a device that controls the flow of electrons in an electrical circuit, which acts as an on-off switch. Similarly, the biological transistor — termed a transcriptor — controls the flow of an enzyme as it moves along a strand of DNA (deoxyribonucleic acid). These cellular building blocks could be used to do anything from monitoring their environment to turning processes on and off in the cells. The findings were reported today (March 28) in the journal Science.

Superman' particle found
<p> Physicists at an underground laboratory have caught an ultra-rare particle in the act of reappearing.</p>
<p> For only the third time, scientists have detected elementary particles called neutrinos in the act of changing from one type, called muon, to another, called tau, on the several-hundred-mile trip between two laboratories.

UFOs over Texas IDed
<p> A strange sight in the Texas night sky over the weekend had many people talking about fireballs and alien invasions. But, alas, the real culprit has been identified, a much more Earthly one.</p>
<p> Police in East Liberty County got a 911 emergency call at around 8:30 p.m. on Saturday from a person reporting "red fireballs in the sky." Responding police officers, along with a dozen locals, described seeing four orange lights moving slowly in a line high in the sky. Police scopes revealed that the objects looked like hot air balloons — complete with flames — but were much smaller and did not have the signature gondola at the bottom.

Master violins mimic human voice
<p> Virtuosos who describe the singing voice of a violin may be on to something. The great violin makers, such as Stradivari and Guarneri, may have designed violins to mimic the human voice, new research suggests.</p>
<p> The research, described in the current issue of Savart Journal, found the violin produced several vowel sounds, including the Italian "i" and "e" sounds and several vowel sounds from French and English.

101 beetles named with phone book
<p> What do you do when you run across hundreds of nameless species of beetle in the wilderness of New Guinea?</p>
<p> No, the correct answer is not "run away screaming" — at least if you're a scientist dedicated to discovering the massive diversity of insect life. Instead, researchers from the German Natural History Museum Karlsruhe and the Zoological State Collection in Munich turned to the phone book to label all the new species.

Strange creature has 7 sexes!
<p> With seven different sexes to choose from, the single-celled organism <i>Tetrahymena thermophila</i> determines its biological mating type in a game of molecular chance, new research finds.</p>
<p> <i>Tetrahymena</i> are oval-shaped protozoa that live in freshwater. These microscopic organisms come in seven different "sexes," or mating types. Any <i>Tetrahymena</i> sex can mate with any other mating type except its own.

Stone Age phallus found
<p> Some remarkable traces of Stone Age life were unearthed recently in northern Israel, including a pit of burned bean seeds and a carving of a penis that's more than 6,000 years old, the Israeli Antiquities Authority (IAA) reported.</p>
<p> Archaeologists are excavating at Ahihud Junction ahead of the construction of a new Israeli railroad line to the city of Karmiel. They found evidence of ancient settlements from two eras: the Pre-Pottery Neolithic period and the Early Chalcolithic period (seventh millennium B.C. to fifth millennium B.C.).
