The spacecraft which made a spectacular landing on a comet last year has discovered a rich array of carbon compounds.
One leading scientist has even described the chemicals as “a frozen primordial soup”.
Kepler-452b is the most Earth-like planet ever discovered, a place with just enough sunlight to possibly support the crops and house plants of life forms like ourselves.
But don’t pack your bags just yet.
Humanity would only have a 12-hour warning about the arrival of a “coronal mass ejection” that could damage the National Grid, pipelines and railway signals, according to a newly released document from the UK Cabinet Office.
The brain is extraordinarily good at alerting us to threats. Loud noises, noxious smells, approaching predators: they all send electrical impulses buzzing down our sensory neurons, pinging our brain’s fear circuitry and, in some cases, causing us to fight or flee. The brain is also adept at knowing when an initially threatening or startling stimulus turns out to be harmless or resolved.
Background music in restaurants and stores may be having a more profound effect on you than you think. In a new study, researchers placed 10 volunteers in different rooms with music from one of three regions—the United States, China, or India—playing on loop.
As of yet, no single factor can explain what causes people to behave in ways labelled psychopathic. But research suggests our genes may play a role.
One gene in particular is linked with an increased risk of violent or aggressive behaviour, studies have found.
New evidence has emerged supporting the idea that marijuana may help rehab patients recover from and kick their addictions to painkillers. The study, published by researchers at Columbia University earlier this month, showed that patients given a form of THC during their recovery experienced less severe withdrawal symptoms and were more likely to complete their treatment course.

A few months back, two puffy, red eyes full of goop landed my toddler in the doctor’s office, where an exam also turned up two ear infections. This double-eye, double-ear whammy led to her first dose of antibiotics, post haste.
Starvation early in life can alter an organism for generations to come, according to a new study in roundworms.
The effects are what Duke University biologist Ryan Baugh terms a “bet-hedging strategy.” In nature, the worms live a boom-or-bust lifestyle in which the occasional famine will devastate the population, but not all of the worms are killed. The survivors are smaller and less fertile, and they acquire a toughness that lasts at least two generations.
THERE’S more to semen than sperm. In many animals, seminal fluid alters both the bodies and sometimes even the behaviour of females. Human semen, too, triggers changes in the uterus, and might have wider effects on women, aimed at just one goal.
For a long time, biologists have considered sex to be an inherent trait of multicellular life, while microbial eukaryotes were considered to be either optionally sexual or purely clonal. From this perspective, clonality in eukaryotes is seen as exceptional.
Look at the long, slender snout and small body of an African golden jackal, and you’d be forgiven if you confused it with the golden jackal of Eurasia. Even researchers have long considered them members of the same species, canis aureus. But a new study says the two are separate species despite their similar good looks
Virtually all experts agree that the happiness dogs feel is comparable to what humans experience, and that it’s similar to how humans feel towards each other.
A 2014 US Center for Disease Control and Prevention (CDC) report (pdf) found that, between 2009 and 2012, 9% of Americans were using a prescription antidepressant at least once a month. Now, a sizable bunch of birds are too.
Thirteen new species of spider have been discovered on Queensland’s Cape York peninsula – adding to the thousands of known species that give Australian wildlife its fearsome reputation.
When it comes to vaccinating their babies, bees don’t have a choice—they naturally immunize their offspring against specific diseases found in their environments. And now for the first time, scientists have discovered how they do it.
When you think about the deadliest animal in the world, what immediately springs to mind? Sharks? Hippos? Crocodiles? While these animals may look the part, the biggest killer amongst us is much more inconspicuous, and it can deliver that one potentially fatal bite without you even noticing. I am of course referring to the mosquito. Mosquitoes kill more people each year than all other animals combined, and on average they kill even more people than humans do.
