Science On Top
The Australian Podcast putting Science on Top of the agenda

More artifacts have been recovered from the Antikythera wreck, the 1st century BC shipwreck discovered in 1900 off the coast of the Greek island Antikythera. None of the newly found artifacts, however, appear to be related to the mysterious Antikythera Mechanism, widely known as the first analog computer.

It had long been thought that volcanic activity on the moon stopped around a billion years ago. Now high-resolution images from NASA’s Lunar Reconnaissance Orbiter (LRO) suggest there was activity as geologically recently as 50 million years ago.

The next stage in fecal transplants could be a simple oral pill. Researchers from the Massachusetts General Hospital have managed to put frozen fecal matter into capsules that can be taken orally. These capsules have a similar 90% success rate against Clostridium difficile infection.

In order to study energy trade-offs in voles, scientists had to shave 120 rodents before re-releasing the furry mammals back into the wild. And then they had to recapture them!

There's a symbiotic relationship that's developed over millions of years between brewer's yeast and fruit flies. Understanding this relationship could give brewers more techniques for making distinctive beers.

The Nobel Prize in Physiology or Medicine 2014 was awarded with one half to John O'Keefe and the other half jointly to May-Britt Moser and Edvard I. Moser "for their discoveries of cells that constitute a positioning system in the brain".
The Nobel Prize in Physics 2014 was awarded jointly to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources".
The Nobel Prize in Chemistry 2014 was awarded jointly to Eric Betzig, Stefan W. Hell and William E. Moerner "for the development of super-resolved fluorescence microscopy".
A team of scientists took soil samples at 596 sites across New York’s Central Park. They analysed the soil samples an discovered 167,000 different kinds of microbes, the vast majority of which were unknown to science.
The characteristics of a previous mate can affect the attributes of a fruit fly's offspring. Even if the previous mate is not the genetic father of the offspring.
Researchers at the Wake Forest Institute for Regenerative Medicine in Winston-Salem, North Carolina are developing artificial penises developed from a patient's own cells. The team is hoping to receive approval from the US FDA to begin human testing the lab-grown penises within five years.

The Ig Nobel Prizes honour achievements that first make us laugh, then make us think. We take a look at this year’s winners: from banana peels to people dressed as polar bears!

PHYSICS PRIZE
A team from Japan for measuring the amount of friction between a shoe and a banana skin, and between a banana skin and the floor, when a person steps on a banana skin that's on the floor.
Banana peel slipperiness wins IgNobel prize in physics

NEUROSCIENCE PRIZE
Scientists from China and Canada for trying to understand what happens in the brains of people who see the face of Jesus in a piece of toast.
University Of Toronto Researchers Find ‘Seeing Jesus In Toast’ Phenomenon Perfectly Normal

PSYCHOLOGY PRIZE
A team from Australia, the UK and the US for amassing evidence that people who habitually stay up late are, on average, more self-admiring, more manipulative, and more psychopathic than people who habitually arise early in the morning.
THE DARK TRIAD: People Who Love The Night Have Psychopathic Traits

PUBLIC HEALTH PRIZE
A number of scientists from the Czech Republic, Japan, the USA and India for investigating whether it is mentally hazardous for a human being to own a cat. Turns out it can be, if you get infected with our old friend Toxoplasma Gondii.
Parasite makes men dumb, women sexy

BIOLOGY PRIZE
A team from the Czech Republic, Germany and Zambia for carefully documenting that when dogs defecate and urinate, they prefer to align their body axis with Earth's north-south geomagnetic field lines.
Dogs align their bodies along a North-South axis when they poop
Do Dogs Line Themselves Up With the Earth’s Magnetic Field to Poop?

ART PRIZE
Three scientists from Italy, for measuring the relative pain people suffer while looking at an ugly painting, rather than a pretty painting, while being shot [in the hand] by a powerful laser beam.
ITALY: Beautiful art eases pain

ECONOMICS PRIZE
ISTAT — the Italian government's National Institute of Statistics, for proudly taking the lead in fulfilling the European Union mandate for each country to increase the official size of its national economy by including revenues from prostitution, illegal drug sales, smuggling, and all other unlawful financial transactions between willing participants.
In Italy, prostitutes and illegal drugs could shrink the deficit

MEDICINE PRIZE
A team from the USA and India for treating "uncontrollable" nosebleeds, using the method of nasal-packing-with-strips-of-cured-pork.
