The US military is considering testing the principle behind a type of space drive which holds the promise of reaching Mars in just three hours. The problem is, as New Scientist explains, it's entirely theoretical and many physicists admit they don't understand the science behind it

Scientists have developed artificial, super-strength muscles which are powered by alcohol and hydrogen.

And they could eventually be used to make more advanced prosthetic limbs, say researchers at University of Texas.

Writing in Science, they say these artificial muscles are 100 times more powerful than the body's own.

Scientists funded by the European Space Agency have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Under certain special conditions the effect is much larger than expected from general relativity and could help physicists to make a significant step towards the long-sought-after quantum theory of gravity.

Scientists can grow frog and mouse meat in the lab, and are now working on pork, beef and chicken. Their goal is to develop an industrial version of the process in five years.

If they succeed, cultured or in vitro meat could be coming to a supermarket near you. Consumers could buy hamburger patties and chicken nuggets made from meat cultivated from muscle cells in a giant incubator rather than cut from a farm animal.

Home chefs could make meat in a countertop device the size of a coffee maker. Before bed, throw starter cells and a package of growth medium into the meat maker and wake up to harvest fresh sausage for breakfast.

Military researchers believe the tongue could be key in their quest to create the super warrior of the future, giving soldiers sensory powers similar to owls, snakes and fish.

Army Rangers with 360-degree unobstructed night vision, Navy SEALs sensing sonar in their heads while maintaining normal vision underwater - scientists at the Florida Institute for Human and Machine Cognition are turning sci-fi into reality.

For the first time, scientists at the Max-Planck Institute for Biochemistry in Martinsried near Munich coupled living brain tissue to a chip equivalent to the chips that run computers. The researchers under Peter Fromherz have reported this news in the online edition of the Journal of Neurophysiology (May 10, 2006).

...The scientists in Martinsried developed a revolutionary non-invasive technique that enables them to record neural communication between thousands of nerve cells in the tissue of a brain slice with high spatial resolution. This technique involves culturing razor-thin slices of the hippocampus region on semiconductor chips. These chips were developed in collaboration with Infineon Technologies AG and excel in their density of sensory transistors: 16384 transistors on an area of one square millimeter record the neural activity in the brain.

...With the resulting novel hybrid system of neural tissue and semiconductor, the scientists take a great step forward towards neurochip prosthetics and neurocomputation.

Scientists at SUNY Downstate Medical Center have discovered a molecular mechanism that maintains memories in the brain. In an article in Science magazine, they demonstrate that by inhibiting the molecule they can erase long-term memories, much as you might erase a computer disc.
