The result is the first ultrasound imaging agent based on genetically encoded gas-containing structures. Shapiro team utilized photosynthetic microorganisms that form gas nanostructures called as vesicles
which the researchers discovered were excellent imaging agents for ultrasound, with several unique properties making them especially useful in biomedical applications.
BETTER THAN MICROBUBBLES Previously, most ultrasound imaging agents were based on small gas bubbles, which ultrasound can detect
The researchers wanted to find another way of making gas-filled structures that could be nanoscale.
In particular, certain photosynthetic microorganisms regulate their buoyancy by forming protein-shelled gas nanostructures called as vesiclesinside the cell body.
These structures interact with gas in a way that is fundamentally different from microbubbles, allowing them to have nanometer size.
In this study, they discovered that gas vesicles are excellent imaging agents for ultrasound. The researchers showed that they were able to easily attach biomolecules to the gas vesicle surface to enable targeting.
In addition, because these structures are encoded as genes, they now have a chance to modify these genes to optimize gas vesiclesultrasound properties.
Already the team has shown that gas vesicles from different species, which vary in genetic sequence, exhibit different properties that can be used to,
for example, distinguish them from each other in an ultrasound image. The journal Nature Nanotechnology reported the team findings e

#Quantum gas goes below absolute zero It may sound less likely than hell freezing over, but physicists have created an atomic gas with a sub-absolute-zero temperature for the first time1.
Their technique opens the door to generating negative-Kelvin materials and new quantum devices, and it could even help to solve a cosmological mystery.
Physicists later realized that the absolute temperature of a gas is related to the average energy of its particles.
Schneider and his colleagues reached such sub-absolute-zero temperatures with an ultracold quantum gas made up of potassium atoms.
This result, described today in Science1, marks the gas s transition from just above absolute zero to a few billionths of a Kelvin below absolute zero.
Another peculiarity of the sub-absolute-zero gas is that it mimics'dark energy''the mysterious force that pushes the Universe to expand at an ever-faster rate against the inward pull of gravity.

The colours show how this gas was moving: blue represents gas that is moving towards us
while red indicates gas that is moving away. Out of 37 galaxies observed these 30 all show gas rotating around the centre of the galaxy meaning they are disc galaxies in the making.
For the first time there is observational evidence for merging galaxies that could result in disc galaxies. This is a large and unexpected step towards understanding the mystery of the birth of disc galaxies says Junko Ueda from the Japan Society for the Promotion of Science.
