Protozoan parasite Toxoplasma gondii rendered mice unafraid of cat odor, even after the infection cleared, according to a study published in PLoS ONE.
Ever wanted to completely forget a bad memory? Anthony reports on the discovery of a gene that could aid in memory extinction and bring to life a real Eternal Sunshine of the Spotless Mind.
Scientists in China have visualized the molecular structure of a hydrogen bond, using a technique called high-resolution atomic force microscopy (AFM).
Sleep consumes a sizable portion of each of our days, but what would happen if we significantly reduced the amount we got on a daily basis? Is your lack of sleep slowly killing you?
Featuring Michael Pollan and based on his best-selling book, this special takes viewers on an eye-opening exploration of the human relationship with the plant world, seen from the plants’ point of view. The program shows how four familiar species — the apple, the tulip, cannabis and the potato — evolved to satisfy our yearnings for […]
With a thick atmosphere, clouds, a rain cycle and giant lakes, Saturn’s large moon Titan is a surprisingly Earthlike place. But unlike on Earth, Titan’s surface is far too cold for liquid water – instead, Titan’s clouds, rain, and lakes consist of liquid hydrocarbons like methane and ethane (which exist as gases here on Earth). When these hydrocarbons evaporate and encounter ultraviolet radiation in Titan’s upper atmosphere, some of the molecules are broken apart and reassembled into longer hydrocarbons like ethylene and propane.
In mediaeval times lefties were believed to be in league with Beelzebub himself, this gave rise to the word sinister from the Latin ‘sinistra’ meaning of the left. Later on scientists proposed that left-handed people had their brains wired differently, which turned out to be only partially true.
We usually don’t think about ice too much, unless there’s none in the freezer and all we have to drink is a warm can of Coke. But the cold, hard, slippery truth is that ice deserves more consideration than that- and not just the kind you put in your drink.
Why can’t we recall being born? It was kind of a big day, so you’d think we’d remember. Anthony looks at how the inner workings of a baby’s brain differs from that of a full grown adult.
Sprayable Energy is exactly what it sounds like — it’s liquid caffeine that you spray onto your skin. It’s also colorless and odorless. For us media folk who wake up early and work long hours, Sprayable Energy sounds like the most magical product ever. But, does it actually work? We made some of our co-workers trade in their morning cup of coffee for some sprays of Sprayable Energy.
Professor Stephen Hawking in a speak at premiere of the documentary film about his life, said that brain ‘could exist outside the body’ and like a program, could be copied onto a computer.
Does the order you’re born in really affect the kind of person you grow up to be? Trace explains if there’s really the impact people say there is.
Scientists at the University of Southampton explain the evolution of flight, with a month-long experiments of a life-sized Microraptor placed in a wind tunnel.
You know what’s funny? Why people laugh. Hank talks about the science of laughter: what makes us laugh, what purpose it serves, and even what it can tell us about our mental and physical health. Hilarious!
