Visitors to Disneyland left with something more than just exhaustion and overpriced souvenirs this month. The Happiest Place on Earth has been identified as ground zero for an outbreak of Measles that has so far infected more than 84 people.

Scientists drilling in the Ross Ice Shelf in Antarctica have been surprised to find translucent fish and other aquatic animals living in perpetual darkness and cold, beneath a roof of ice 740 metres thick.

There's a promising new stem cell treatment for the most common form of Multiple Sclerosis. After three years, 86 percent of trial patients have had no relapses, and 91 percent are showing no signs of MS development.

In 2003, the Mars lander Beagle 2 was lost during its landing on Mars. Eleven years later the Mars Reconnaissance Orbiter has found it - intact but only partially deployed.

The 79AD eruption of Mount Vesuvius is famous for burying - and preserving - the city of Pompeii. But it also preserved another nearby town, Herculaneum. A new X-Ray technique is helping archaeologists read scrolls found there without opening and damaging them.

SoT Special 17: Dr. Karl Kruszelnickihttp://scienceontop.com/Special17Dr. Karl is one of Australia's best known science communicators. He is the author of 36 popular science books, appears regularly on radio in Australia and the UK, and he is the Julius Sumner Miller Fellow in the Science Foundation for Physics at the University of Sydney.Ed sat down with Dr. Karl in December, shortly after the National Skeptics Convention where Karl was a speaker. Together they discussed climate change, science coverage in the media, dealing with denialists on Twitter, a man who can hear what you say before he sees your lips moving, a rare cure for cancer, Alan Turing and the Apple logo, and the origins of the term 'selfie'.http://scienceontop.com/Special17

Some of our best science stories from 2014. Comet landings, Ebola outbreaks, retracted stem cell studies, faecal transplant capsules and more!

Rosetta has analysed the water found on comet 67P/Churyumov–Gerasimenko and found significant differences compared to water on Earth. This may weaken the theory that comets brought water to an early Earth.One of the most common minerals on our planet finally has a name. We've known Brigmanite exists for a long time, but it was a surprising source that gave scientists the opportunity to study it up close.The New Horizons spacecraft has just been successfully woken up, and is on track to giving us our first up-close look at Dwarf Planet Pluto next year.And the Dawn space probe has just taken its first low quality photo of minor planet Ceres, the largest object in the main asteroid belt. Dawn is expected to arrive at Ceres in early 2015.Traditional forensic DNA tests can't tell the difference between identical twins, but a new test may change that. A preliminary hearing is scheduled for early next year to determine whether evidence from the test is admissible in US Courts.A three-year-old child died and several young children fell ill in Victoria, Australia after drinking raw milk. We discuss why unpasteurised milk is legally sold in Australia as 'bath milk' and why some people choose to drink it.

Is HIV evolving in to a milder, less deadly virus? A new study suggests it's taking longer for HIV infections to cause AIDS and that this is the result of mutations in the virus.NASA's test launch and flight of the Orion Multi-Purpose Crew Vehicle was a success. This was an important step in an ambitious plan to send astronauts to an asteroid and then perhaps send astronauts to Mars.Biologists at Santa Fe College in Florida have found that our desire to drink alcohol, and our ability to break down the ethanol, dates back about 10 million years.Blood plasma from Ebola survivors contains antibodies that might trigger an immune system response in patients, a bit like a vaccine. This week the Bill & Melinda Gates Foundation announced that early next year it plans to begin clinical trials in Guinea to test if such blood transfusions are effective.Researchers from North Dakota State University have used Fructose to make a new type of plastic that breaks down completely after just three hours of UV light exposure. It can then be fully recycled.

Professor Rob Morrison and Dr Deane Hutton are Australian science communication heroes. Together they hosted the children's science TV show Curiosity Show, which ran for 18 consecutive years from 1972 to 1990. Ed and Lucas caught up with them at TEDxCanberra to talk about the show and its recent new episode, what they've done since then, and their views on science communication and education.

Rob mentions Duck Quacks Don't Echo (UK) as an example of good current science television.

More details on Philae's rough landings, and the future of the first probe to land on a comet. Professor Monica Grady's reaction to the landing, the sound of the landing, and the comet 'sings'.When a pair of scientists found their experiment contaminated from the DNA Isolation kits they were using, they set out to see if other experiments were similarly contaminated.Researchers at Australia's James Cook University have discovered tiny zircon crystals on Vanuatu. But surprisingly, they seem to have originally come from Australia.Scientists have descended into one of the three mysterious craters that have formed this year in Siberia, onto a frozen lake. The most likely explanation for the craters is a "catastrophic destabilization of Arctic methane stores due to human-caused warming".

Shayne and Ed are joined by Dr. George Aranda, curator of the Science Book A Day blog and co-host of the Big Ideas Book Club in Melbourne. George is running a Pozible crowdfunding campaign to investigate the use of 3D Printers in school education.Scientists from University of Bern in Switzerland have developed a new approach to the treatment of severe bacterial infections without the use of antibiotics.The prestigious Royal Society Winton Prize for Science Books has been awarded to Mark Miodownik, author of Stuff Matters. The book is an enthralling account of Mark's love of material science, and the extraordinary properties of the materials in our everyday lives.Cornell University’s Ruth Ley and her colleagues have identified one bacterial taxon, the family Christensenellaceae, as the most highly heritable group of microbes in the human gut.And for the first time ever, humans have landed a probe on a comet moving at 50,000kph.

A team of bioengineers is trying to make artificial milk in a lab and without animals. They call it "Muufri".In order to study penguins up close, without disturbing them, researchers from Centre National de la Recherche Scientifique used small baby-penguin sized rovers. The rover - cleverly disguised as a penguin - was able to monitor penguins and even quick-tempered elephant seals without alarming the animals.A man who had brain surgery for a serious medical condition unexpectedly found his arachnophobia cured.It was a bad week for commercial spaceflight, after Orbital Sciences' Antares rocket exploded seconds after launch and then Virgin Galactic's SpaceShipTwo broke apart during a test flight.
