South Koreans clone cats that glow in the dark
In a side-effect, the cloned cats glow in the dark when exposed to ultraviolet beams.
A team of scientists led by Kong Il-keun, a cloning expert at Gyeongsang National University, produced three cats possessing altered fluorescence protein (RFP) genes, the Ministry of Science and Technology said.
"It marked the first time in the world that cats with RFP genes have been cloned," the ministry said in a statement.
"The ability to produce cloned cats with the manipulated genes is significant as it could be used for developing treatments for genetic diseases and for reproducing model (cloned) animals suffering from the same diseases as humans," it added...

Study hints that fruit flies have free will
Future research delving further into free will could lead to more advanced robots, scientists added. The result, joked neurobiologist Björn Brembs from the Free University Berlin, could be "world robot domination."
"Seriously though," Brembs said that programming robots with aspects of free will "may lead to more realistic and probably even more efficient behavior, which could be decisive in truly autonomous robots needed for planetary exploration"...

Waterfowl wage genital warfare
The genitalia of the females of these species have at times apparently evolved to make it harder for males to successfully impregnate them, according to new findings that shed light on the eternal war of the sexes.
Most birds lack phalluses, organs like human penises. Waterfowl are among the just 3 percent of all living bird species that retain the grooved phallus found in their reptilian ancestors.
Male waterfowl are especially unusual in that their phallus length varies greatly among different species, ranging from a half-inch to more than 15 inches long. They also display a remarkable level of diversity how elaborate they are, ranging from smooth to covered with spines and grooves.
Scientists had speculated that male waterfowl evolved longer phalluses to give them a competitive edge over those not as well-endowed when it came to successfully fertilizing females...

Genetic Discrimination Ban Clears House; Senate OK Expected
If legislation passed Wednesday by the House of Representatives becomes law, it will be illegal to deny a job or health insurance on the basis of a person's genetic makeup.
With more links drawn between genetic profiles and disease predispositions every day, supporters of the Genetic Information Nondiscrimination Act say the bill will ease patients' worries of being singled out for faulty genes.
“GINA will do more than stamp out a new form of discrimination,” said Louise Slaughter (D-New York) who introduced the bill. “It will allow us to realize the tremendous potential of genetic research without jeopardizing one of the most fundamental privacies that can be imagined.”
Such discrimination is rare, but supporters of the bill worry that as genetic testing becomes common and scientists chart the complex links between genes and health, profiling might also increase...

Marmosets may carry their sibling's sex cells
Marmosets (Callithrix kuhlii) are unusual in that most pregnancies result in non-identical twins, and a high proportion of those result in chimerism. Genetic analysis of these twins shows that all tissues - including skin, hair, brain, lung and muscle - may contain cells derived from the sibling twin...
