sci-universe:

I thought I should post something about my physics studies, sooo this is a practical work I did in a course called Physical Measurements. (I’m showing a fraction of it because it’s the fun part, I assume you don’t want to see the 5 pages of following calculations.) Among other tasks, I had to generate different figures (called Lissajous curves) for relationships between the frequencies of vertical and horizontal sinusoidal inputs by using an oscilloscope (see above). It’s a laboratory instrument which is used to display and analyze the waveform of electronic signals. In effect, the device draws a graph of the instantaneous signal voltage as a function of time. The gifs show what it looked like in practice, and graphs what it looks like in theory.

These Bacteria Are Wired to Hunt Like a Tiny Wolf Pack
There is an elaborate stealth communication network in the Earth beneath your feet. This smart web acts like a superorganism, fortifying defensive capabilities and coordinating deadly attacks on unsuspecting targets. But it’s not run by the NSA, the CIA, or the military. This web is made of bacteria.
A team of scientists led by Manfred Auer at Lawrence Berkeley National Laboratory have used cutting-edge 3-D microscopy to identify a new mechanism for bacterial networking. They observed elaborate webs of a common soil bacterium, Myxococcus xanthus, connected by thread-like membranes. This system of cellular pipelines suggests that some bacteria have evolved complex ways to deliver molecular cargo out of sight from snooping neighbors. Their work appears in the journal Environmental Microbiology.

Scientists See Chemical Bonds Between Atoms
In an amazing work of microscopy, scientists have gotten a high-resolution view of a molecule and its chemical bonds. What’s more, the Lawrence Berkeley National Laboratory researchers got a peek at the molecule as it broke and reformed bonds after undergoing a chemical reaction.
Their images show a molecule, on the left above, which has 26 carbon and 14 hydrogen atoms structured as three connected benzene rings. The molecules on the right are the two most common products that result after the molecule is heated to 90 degrees Celsius.

congenitaldisease:

Decellularization is a tissue engineering technique designed to strip out the cells from a donor organ, leaving nothing but connective tissue that used to hold the cells in place. This scaffold of connective tissue - called a "ghost organ" for its pale and almost translucent appearance - can then be reseeded with a patient’s own cells, with the goal of regenerating an organ that can be transplanted into the patient without fear of tissue rejection.This is in the experimental stage.
