A new view of 20,000-year old supernova remnant W50 provides more clues to the history of this giant cloud that resembles a beloved endangered species, the Florida Manatee. W50 is nearly 700 light years across,  so it covers two degrees on the sky - the span of four full Moons






The UK government needs to monitor surrogate pregnancy more carefully, says Eric Blyth, professor of social work at the University of Huddersfield. Couples seeking to build a family, and surrogate mothers overseas who help them, are in danger of emotional, physical and financial exploitation.


Wolves and dogs are genetically very similar, so why did dogs become "man's best friend" while wolves remain wild?

Kathryn Lord at the University of Massachusetts Amherst suggests the different behaviors are related to the animals' earliest sensory experiences and the critical period of socialization.  Not much is known about sensory development in wolf pups and assumptions are usually extrapolated from what is known for dogs - but there are significant differences in early development between wolf and dog pups, chief among them timing of the ability to walk. 


Most moons look ancient because their faces are pockmarked by thousands of craters but Titan, Saturn's largest moon, gets constant retouching because its craters are getting erased. Dunes of exotic, hydrocarbon sand are slowly but steadily filling in its craters, according to new research.

Titan is the only moon in the solar system with a thick atmosphere, and the only world besides Earth known to have lakes and seas on its surface. However, with a frigid surface temperature of around minus 290 degrees Fahrenheit (94 kelvins), the rain that falls from Titan's skies is not water but instead liquid methane and ethane, compounds that are normally gases on Earth.


In America, the government banned incandescent light bulbs, convinced that if they banned them, the free market would replace it with something affordable, effective and efficient. In reality, since there was no good alternative, people just horded light bulbs. The automobile did not supplant the horse and buggy because horses were banned and banning regular light bulbs was not going to make compact fluorescent bulbs or light emitting diodes popular. 


While every study ever done shows that people who consume fewer calories than they burn will lose weight, it is as well known that some people cannot or will not eat less or exercise. For those people, laparoscopic adjustable gastric banding – lap banding – is a safe and effective long-term strategy for managing their obesity, according to the findings of 15-year follow-up study of patients treated in Australia. 

The follow-up study found a significant number of lap band patients maintained an average weight loss of 26 kilograms for more than a decade after their procedure.
