What do 3D printing, jelly, liver transplants, chainmail, dental fillings, ferrofluids, and the Six Million Dollar man have to tell us about our future? Materials scientist and engineer Mark Miodownik lets us know in this Royal Institution lecture
"We measure, in a single experiment, both the radiation pressure and the torque due to a wide variety of propagating acoustic vortex beams.
The results validate, for the first time directly, the theoretically predicted ratio of the orbital angular momentum to linear momentum in a propagating beam. We experimentally determine this ratio using simultaneous measurements of both the levitation force and the torque on an acoustic absorber exerted by a broad range of helical ultrasonic beams produced by a 1000-element matrix transducer array." In other words, science has created the sonic screwdriver

Using a 3-D petri dish,
Researchers at Brown University and Women & Infants Hospital of Rhode Island have built a completely functional artificial human ovary
that will allow doctors to harvest immature human egg cells (oocytes) and grow them into mature, ready-to-be-fertilized human eggs
outside the body. (In vitro
) The advance could eventually help preserve fertility for women facing chemotherapy
or other medical treatments that may be destructive to ovarian folliculogenesis. Press Release.

Although a cellphone is about as close to a Star Trek communicator as you can get, something more practical has come along to make you feel like you're finally living in the future. The Standoff Patient Triage Tool (SPTT) is nearly a Starfleet medical tricorder
: it can detect pulse, body temperature, and respiration from an injured person at a distance of forty feet
, allowing first responders to identify the injured before setting foot into a dangerous situation.
Scientists Repurpose Adult Cells
- "Scientists have transformed one type of fully developed adult cell directly into another inside a living animal, a startling advance that could lead to cures for a variety of illnesses and sidestep the political and ethical quagmires associated with embryonic stem cell research."

"The next president of the United States of America will control a $150 billion annual research budget, 200,000 scientists, and 38 major research institutions and all their related labs. This president will shape human endeavors in space

to the Democratic
candidates' positions on science
issues. But to help further clarify their positions

Professor becomes world's first cyborg
Surgeons have carried out a ground-breaking operation on a cybernetics professor so that his nervous system can be wired up to a computer.
It is hoped that the procedure could lead to a medical breakthrough for people paralysed by spinal cord damage, like Superman actor Christopher Reeve.
Prof Warwick believes it also opens up the possibility of a sci-fi world of cyborgs, where the human brain can one day be upgraded with implants for extra memory, intelligence or X-ray vision.
The medical possibilities with this are amazing, so why does it make me feel so uneasy?
