2016/02/08

The seventh period on the periodic table is now complete, after four new elements have been officially verified. Elements with atomic numbers 113, 115, atomic numbers 113, 115, 117 and 118 have been confirmed and will get permanent names soon. The irukandji jellyfish - actually a number of species of jellyfish - are the most venomous box jellyfish in the world. A leading researcher has now warned that the jellyfish, usually found in the warmer northern waters of Australia, are being found further

Robin Ince is a celebrated British comedian. He has built his career mixing science and comedy, on television, radio, podcasts and in his stand-up routines. He's perhaps most famous as a co-host with astrophysicist Brian Cox on BBC4's Infinite Monkey Cage radio show and podcast.Ed managed to sit down with Robin in April last year, to discuss all things comedy and science. From raising sceptical and scientifically literate children, to whether science can bring happiness!

Fast Radio Bursts are sudden, very short but very intense blasts of radio waves that have so far defied explanation. But now the most detailed study so far has provided some clues to the origins of FRBs - they MIGHT come from starquakes. Probably not aliens. While bees are certainly the most efficient pollinators, a new study suggests that other insects - like flies, wasps, beetles and butterflies - are just as important for the success of the world's crops. It's like having a backup plan for

2015/12/09

Chinese scientists have found bacteria that are resistant to one the 'last resort' antibiotics. The gene for this resistance has been found in 15 percent of meat samples and can spread to other bacteria very easily. Biologists at Tufts University have induced flatworms to grow the heads and brains of other flatworm species, without altering the worm's genome. Researchers have sequenced the genome of the tardigrade, or 'water bear'. This tiny but nearly indestructible creature has the most foreign

For the first time, neurosurgeons at in Canada claim to have found a way to deliver chemotherapy drugs directly to the brain, crossing the famed blood brain barrier. Women infected with hookworms seem to have decreased fertility, while women with roundworms seem to be more fertile. Because parasitic worms are weird. There's some growing evidence that suggest repeated vaccination against different flu strains might diminish the flu vaccine’s effectiveness. You should still get the shot,

A study of 345 women by The University of Essex concludes that no woman is"totally straight". Well, it's a bit more complicated than that. In Australia, forty volunteers are about to have hookworms injected into their bodies to see if a radical treatment can alleviate some of the symptoms of coeliac disease. Two possible ice volcanoes have been identified on the surface of Pluto thanks to New Horizons' study of the minor dwarf planet. Instead of molten rock, these volcanoes would eject slushies of

The first case of a human falling ill from cancer cells contracted from a parasitic tapeworm has been reported in Columbia. And in an unrelated story, a Californian man has had a live tapeworm removed from his brain in a potentially life-saving operation. The Rosetta probe orbiting 67P/Churyumov–Gerasimenko has surprised everyone by detecting large amounts of molecular oxygen on the comet.

The World Health Organisation has officially classified processed meat as "carcinogenic", and red meat as "probably carcinogenic". However, this doesn't really tell you anything about the level of risk associated with meat. You're probably fine. Electric eels can deliver a strong shock, but they can deliver twice the shock by curling around and trapping their victim between head and tail.

Researchers have found neurons in nematode worms that help them learn when to prioritise mating over eating. This does not necessarily have anything to do with humans. A large team of scientists have published a paper about a strange star, KIC 8462852, which has an unusual pattern of dimming and brightening. One possible - though remote - explanation they have proposed is a Dyson's sphere. Thanks again to some zircon cyrstals, researchers may have found evidence of ancient microorganisms that lived

Dark streaks seen on the surface of Mars are likely to be periodic flows of liquid water – something previously though almost impossible. The tongues of the long-tongued bumblebees in Colorado are shorter than archived long-tongued bumblebees from forty years ago. This appears to be an adaptation to climate change and while it's good news for the bees, it could be bad news for the flowers they feed on. Four kinds of gut bacteria have been found to havea strong preventative link to asthma. But

A new theory about our solar system's history proposes that there was a fifth giant planet early on that influenced Neptune's orbit and was flung out into interstellar space. Two independent teams have manipulated a piece of viral protein so it can teach immune systems to fight whole groups of viruses, rather than a single strain. This could be the first step towards a universal flu vaccine and could eventually eradicate influenza altogether. Over the last three years Professor Brian Nosek from the

Scientists at the American Fisheries Society annual meeting have called for changes to how decisions are made in fisheries.

In an important step forward for human space exploration, astronauts on the ISS have eaten lettuce grown on the station. They liked it. Despite having only a 36% success rate, the new malaria vaccine called 'Mosquirix' has been endorsed for young African children.

In 2011 a tornado ripped through Joplin, Missouri, killing 158 people. It also brought with it a rare flesh-eating fungus that killed another five. The first two species of 'venomous' frogs have been discovered - the hard way - in the Caatinga forests of Brazil. And you really don't want them to headbutt you. There's a parasitic wasp that uses mind control on spiders to force them to spin cocoons. Because nature is like that. We mention this David Attenborough video about the Cordyceps fungi that
