Man-made electromagnetic noise is affecting migratory birds. But it's not wi-fi, microwaves or any of the usual culprits - just good old fashioned AM radio.

US scientists have developed artificial DNA - X and Y base pairs - which then replicated with the normal G, A, T and C molecules when the cell divides. This could pave the way for new methods of developing drugs and other chemicals. Or Godzilla.

A study with mice involving exercise, electric shocks and drugs have given new insights into how memories are formed, and why you can't remember being a baby.

When bacteria can't sense other bacteria around them, they begin to mutate faster. If we could trick them into thinking they're not alone, we could slow down the development of antibacterial resistance.

The average height of British soldiers fighting in the First World War was 168cm. Today the average height for men of the same age is 178cm. A new study suggests that height change was not because of diet, but rather urbanisation.

Sea turtle hatchlings, trying to find their way to the ocean have been confused by well-lit resorts and apartment buildings. A new project, funded in part by fines from the 2010 Deepwater Horizon oil spill, aims to fix this problem with new LED lights.

After being first discovered in 2010 by a team in Russia, super-heavy element 117 (Ununseptium) was found again by researchers in Germany. The confirmation means Ununseptium could shortly find its way onto the periodic table as the heaviest element ever made.

Evolutionary biologist and author of Sex, Genes & Rock 'n' Roll Professor Rob Brooks joins us to talk beards, monogamy and evolution.

Beards seem to be popular now, but we may be approaching 'peak beard', where beards are so common they lose their novelty appeal.

Do babies cry at night to stop their parents having more babies? Evolutionary biologist David Haig thinks they may be unintentionally sabotaging their parents' sex lives.

A ten year, worldwide project has finally sequenced the Tsetse fly genome. The findings from this massive effort could help in the fight against sleeping sickness, which kills nearly 10,000 people a year.

Some dolphins use sea spongers as tools to help forage for food, and it appears to be affecting their diet.

The US Food and Drug Administration has approved a new test for human papillomavirus, but while it could one day replace a pap smear, it still requires a cervical sample.

The world's longest continuously running lab experiment, The Pitch Drop, finally drops for the ninth time.

Cephalotes ants can glide to nearby trees when they find themselves skydiving. Also they use their heads as shields.

The most Earth-like exoplanet yet has been discovered, just 10% bigger than our planet.

We all know malaria is spread by mosquitoes, but in 1995 in Taiwan there was an outbreak that spread throughout a hospital without any mosquito assistance.

Continental drift could have been started by a massive meteorite impact 3 billion years ago.

Fossilised daddy longlegs reveal the arachnids had an extra pair of eyes 305 million years ago. And weren't cute then, either.

A new study suggests that even if there was liquid water on the surface of Mars billions of years ago, there wasn't enough atmospheric pressure to keep it liquid for long.

The UK Government has stockpiled over £500m worth of the antiviral drug Tamiflu. A study now finds that the drug would have little to know effect on the spread of influenza or the duration of flu symptoms. According to medical journalist Ben Goldacre, this finding is symbolic of substantial transparency issues within the pharmaceutical industry.

Ten world-class violinists tested expensive 'Old Italians' - Stradivarius and del Gesu violins - against modern, much cheaper instruments. The modern instruments were overwhelmingly preferred.

We have six basic facial expressions, but computer software has shown we combine them to display hybrid emotions, like 'happily surprised' or 'angrily surprised'.

Scientists have long suspected that Saturn's sixth largest moon, Enceladus, held large amounts of water beneath its icy surface. But now gravity measurements have found a large ocean below the southern polar region.

Genetic modification could allow us to grow plants that are more easily broken down to make biofuels and paper.

Contrary to a lot of media reporting, rats might not be completely off the hook when it comes to spreading the Black Death.

On April 21st, NASA plans to crash a recent lunar probe, LADEE, into the moon.

A woman with a bone disorder has had her cranium replaced with a 3D printed one, and shows no sign of rejection.

Skeletons unearthed last year from a burial ground in London may suggest that the Black Death plague was spread via the air, not tick bites from rats.

The rubber hand illusion is an old trick where your brain is fooled into thinking a rubber hand is your own. Psychologists in Italy have now made people believe the hands were made of marble. Because Italy.

Could the Permian extinction, the largest mass-extinction on Earth, have been caused by the farts of single-celled microbes?

Obakata, lead researcher in the STAP papers, found guilty of fabricating data. And an acupuncture trial gets undue media attention.

Giant pythons in Florida's everglades can navigate vast distances, and we're not sure how.

For the first time ever, an asteroid in our solar system has been discovered with a ring system.

Dark chocolate is good for you, but it's the bacteria in your gut that make it so.

Astronomers have discovered an icy body with an orbit so big it never gets closer than 12 billion kilometers from the Sun!

The most comprehensive infrared search of our skies has found no trace of "Planet X", the mythical giant planet on the edge of our solar system.

The troublesome Western Corn Rootworm is developing a resistance to the genetically modified corn designed to thwart it.

British archaeologists have found what they say is the world's oldest complete example of a human being with metastatic cancer.

Tracing human migration across the pacific 3,000 years ago is tricky, but tracing the chickens they brought with them might be a better method.

Climate For Change is a exciting grass-roots activism movement starting up in Melbourne, Australia. Katerina Gaita joins us to explain what they're doing and how you can be part of it.

Last Monday, astronomers announced what has been described as "the biggest thing since dark energy" - detection of gravitational waves from the afterglow of the big bang. We got astronomer Dr. Alan Duffy from Swinburne University on to tell us what that means, and what it says about the very early stages of our Universe.
