Growing Space Debris Problem has to be Tackled Urgently

Space debris is a growing problem, comparable to littering trash in orbit, because it has the tendency to multiplicate itself exponentially as soon as there are enough objects in space and they collide with each other. The urgent need to tackle this problem was now highlighted by the 6th European Co...

3D-Bioprinted Human Liver Tissue Functional, Replacement Organs the Goal

3D bioprinted human liver tissue was successfully created by the company Organovo, revealed at the annual Experimental Biology conference this week in Boston. The mini-livers are just half a millimetre deep and 4 millimetres across but can perform most functions of the real thing.

Sun Observing IRIS Satellite to Launch in May, Crucial for Better Space Weather Forecasts

Space weather, caused by the extremely energetic dynamics of the enormous fusion fire of our Sun, can have big effects on our technological infrastructure -- mostly on satellites orbiting around Earth, but in extreme cases even on the electrical and electronical infrastructure on the planet's surfac...

Atomic-Scale ReRAM Element Puzzle Solved, New Possibilities for Next-Gen Memory

Resistive memory cells (ReRAM), atomic scale elements with a huge potential to further accelerate microchips, were surprisngly found to have even greater potential than previously known. They are not purely passive components like current memory cells but must be regarded as tiny batteries, research...

Target Painting Cancer Cells is the Surprising Mechanism Behind Effective Compound

Thanks to a new laser-based microscopy method, scientists could discover why a particular cancer drug is surprisingly effective at killing cells -- findings that could in a next step be used to aid the design of future similar or even more effective cancer treatments. Turns out that the effect works...

Billion Year Old Submerged Crust Resurfaced From Volcano Found

Because oceanic crust sinks at certain points deep into Earth's mantle, scientists have long assumed that lava erupting from some oceanic volcanoes should contain materials from the early Earth's crust. But any prove of this phenomenon was missing -- until now.

Using Graphene to Grow Nanowires Yields Unexpected and Useful Structure

A new phenomenon was discovered by chance when experimenting with growing nanowires of a compound semiconductor on top of a sheet of graphene. The team of University of Illinois engineers that conducted the experiments were surprised to find the very useful trait that the self-assembled wires formed...
