By definition, one can't see a black hole itself, only its effect on the light of intervening stars. And without some serious equipment, even that's a tall order. Luckily for all us amateur astronomers, Thomas Müller and Daniel Weiskopf of the University of Stuttgart, Germany, have created a simulation that uses actual star data to calculate exactly what seeing the Schwarzschild black hole would look like.

Scientistsu, engineers, and doctors yearn for tiny sensors to record a vast array of events in the world's many hard-to-reach places. And so far, the tradeoff between battery life and size has prevented sensors from becoming small enough to fit unobtrusively in the human body, or inside very small machines. Now, University of Michigan researchers seem to have solved that puzzle by creating a chip that draws energy through solar power, heat, or movement.

Bark beetles plague the forests of Canada so furiously you'd think rivers of blood and the death of the firstborn would follow hot on their heels. So far, no one has stopped the beetle rampage that has destroyed 33 million acres of trees in British Columbia. However, scientists at Northern Arizona University (NAU) may have devised a way to turn back the beetle tide using sound recordings.

The male birth control pill has lingered for years tantalizingly just out of reach, in the realm where rumor meets science. Recently developed hormonal and mechanical contraceptives never found an audience, serving only to highlight the absence of a male pill. Now, an examination of how smoking pot lowers fertility may make the male pill more than a persistent rumor.

The difficulty of supplying remote outposts across rugged terrain has contributed to many of the deadliest moments in the Afghan War, by preventing the delivery of weapons and ammo to engaged soldiers, forcing supplies to travel over dangerous roads, or turning helicopters into vulnerable targets. Last June, the Marines put out a call for a helicopter UAV to solve those problems. Now, with a successful demonstration at Utah's Dugway Proving Grounds, the Marines might have found their robocopter.

For cybersecurity wonks who see Chinese agents or al Qaeda hackers lurking behind every email from a Nigerian prince, this was one hell of a busy week.

The DIY miniature satellites known as CubeSats have a lot going for them. They're cheap, they're easy to program, and they're small. That last benefit also adds a downside, in that the CubeSats are too small to sport any propulsion systems. MIT is looking to change that by creating an ion propulsion system so small that it will take up less than 10 percent of the already tiny Cubes.

Over five years ago, scientists succeeded in teleporting information. Unfortunately, the advance failed to bring us any closer to the Star Trek future we all dream of. Now, researchers in Japan have used the same principles to prove that energy can be teleported in the same fashion as information. Rather than just hastening the dawn of quantum computing, this development could lead to practical, significant changes in energy distribution.

Over 70 years ago, scientists invented aerogel, the least dense solid known to man, and an insulator four times more efficient than fiberglass or foam. Famously, according to Dr. Peter Tsou of NASA's Jet Propulsion Laboratory, "you could take a two- or three-bedroom house, insulate it with aerogel, and you could heat the house with a candle. But eventually the house would become too hot."

Unfortunately, aerogels remained so expensive and unwieldy that only NASA used them with any regularity. However, thanks to recent production advances, aerogel insulation is now available and affordable for consumer purchase.

In a study that challenges the diagnosis of vegetative state, doctors found that the brain of a seemingly unconscious, vegetative man responded to yes-or-no questions in the same fashion as an alert, conscious person. This discovery not only complicates the medical definition of consciousness, but seems to call into question centuries of philosophy dealing with the nature of life and the self.
