This summer's crippling famine in Somalia, which has killed tens of thousands of people and led half a million more to seek refuge in Kenya, is notable for many reasons — but the theft and sale of life-saving aid is arguably one of the worst. A new project could be one way to prevent such atrocity in the future: Use drones to drop food and drugs right where they're needed, no human intervention required. Enter the Matternet.
The latest news from the Large Hadron Collider: scientists still cannot explain why we’re all here. In the most detailed analysis of strange beauty particles — that’s what they’re really called — physicists cannot find supersymmetric particles, which are shadow partners for every known particle in the standard model of modern physics. This could mean that they don’t exist, which would be very interesting news indeed.
This pointy-nosed shrew, a new fossil find from China, may be the earliest grandmother of all placental mammals, scientists report in a new study. Or perhaps she is the oldest great-aunt. Either way, it’s another big find this week in paleontology.
Social media can be problematic for professionals who don't want their bosses to see unflattering college party photos. But it’s even worse for people whose livelihood literally depends on anonymity, like undercover cops. What happens if the gang you’ve infiltrated finds your grinning mug in Facebook photos from the police union annual picnic?
If you live in the eastern time zone, odds are you're battening down the hatches in advance of Hurricane Irene, a Category 2 monster threatening much of the eastern seaboard. Coastal communities are under mandatory evacuation orders in several states. This NASA Goddard image from Friday morning makes it clear this storm is no joke.
Doctors whose bodies are regularly exposed to x-rays may be adapting at the cellular level to protect themselves against radiation, according to a new study. The research hints that humans could adapt to withstand radiation exposure.
Astronomers just spotted a brand-new supernova mere hours after it exploded, thanks to a robotic telescope and some smart computer algorithms. Now they’re scrambling to use as many telescopes as possible, on Earth and in space, to observe the star’s death throes.
Whether we’re engrossed in an activity or the alarm clock simply fails to chime, we’ve all been in situations when we say we’ve lost track of time. But our brains have not really lost track at all. A specific group of cells in the brain’s memory center is encoding for the passage of time, researchers report. These “time cells” are key to our perception of sequences of events.
A new tooth-regenerating paste could reverse bacterial-induced tooth decay, sweeping dental drills into the dustbin of history. Hopefully.
As your hygienist probably told you, tooth decay happens when bacteria in plaque dissolve your enamel, creating cavities. Eventually the cavity gets big enough that your dentist has to take out the decay and drill a hole that can be filled with resin, gold or something else. But a new treatment developed at the University of Leeds in the UK reverses the decay, allowing your teeth to rebuild themselves.
Using NASA’s Wide-field Infrared Survey Explorer telescope, astronomers have finally spotted a collection of ultra-cool brown dwarfs they have been hunting for more than a decade. These tepid almost-star orbs are nearly impossible to see with a normal telescope, but WISE’s infrared vision was able to pick them out.
