Robopenguin rolled into our hearts
In November, researchers introduced the world to a rather cute remote-controlled rover disguised as a baby penguin, designed to monitor real penguin populations in the Antarctic. The bogus bird certainly had the real ones fooled – even notoriously shy emperor penguins tried to communicate with it and let it join a crèche of chicks. The pretend penguin will allow scientists to monitor the effects of climate change on wild populations without stressing the birds out or disrupting their natural behaviour.
The oldest fossilised sperm was found, and it was enormous
In May, scientists revealed supersized sperm fossils they’d found in Queensland, which are at least 16 million-years-old. The gargantuan gametes are ten times as long as the animals that produced them – crustaceans called ostracods – and 20 times the length of human sperm. The scientists used X-rays to figure out how the giant sperm fit inside the bodies of animals a tenth of their size, but just why the sperm are so large remains a mystery.
Female hurricanes were deadlier than males
Rudyard Kipling probably wasn’t thinking about the weather when he penned his poem ‘The female of the species is more deadly than the male’, but in June, US scientists claimed it may be true of hurricanes. Comparing the death tolls of hurricanes with male and female names between 1950 and 2012, they found the females have, on average, killed more than the males. Further experiments suggested the assumption that males are the more aggressive and dangerous sex may lead people to underestimate the danger posed by female hurricanes. The result is a reluctance to evacuate, increasing the number of fatalities. But the research was not without its critics – other scientists said the facts that all hurricanes were ‘female’ until 1979, and that average fatalities have generally decreased over time, rendered the results meaningless.
The oldest human poo revealed Neanderthals made friends with salad
In June, scientists announced the results of picking through some 50,000-year-old fossilised faeces they stumbled upon while studying an ancient Neanderthal fire-pit in Spain. Analysing the crystallised crap, which is the oldest human poop ever discovered, they found evidence of plant matter as well as meat, revealing that our ancient cousins enjoyed a side of berries, nuts and other vegetables with their mammoth steaks. The petrified poop also revealed the Neanderthals were infested with various types of parasitic worm, enough to make a modern human very sick indeed.
Scientists found a shocking way to induce Inception-style dreams
In May, German scientists said they’d found a way to induce lucid dreaming – the state in which you are conscious during a dream, aware you’re dreaming, and able to control the dream’s plot. Delivering a mild electric current to the frontal and temporal brain regions of 27 dreamers altered their neural patterns. A particular type of brain wave activity called gamma activity increased, and the subjects became aware they were dreaming, and were able to exert greater control over the dreamworld.
